<Embodiment>
<Structure>
FIG. 1 is a diagram showing an example in which a liquefaction promoting device 1 suitable for a heat pump system in a data center is used in a heat pump system. The heat pump system includes various forms such as an air conditioner, a refrigerator, a refrigerator, a water heater, a freezer warehouse, and a chiller. It is applicable not only to those that consume electric power but also to those that use other energy such as gas heaton. Moreover, not only when designing a new heat pump system, it is also possible to additionally install it in an existing heat pump system later.

A heat pump system is a device that draws heat from a cold object and gives it to a hot object. It is used for the purpose of further cooling cold objects and further warming hot objects. A device that performs both cooling and heating by switching is also a heat pump.
The fluid referred to in the present specification is a fluid that circulates in a compressor, a pipe, a heat exchanger, and the like in a heat pump cycle. Includes refrigerant and refrigerating machine oil. The fluid is in a gas state, a liquid state, or a gas-liquid mixture state depending on which process in the heat pump cycle. CFCs are no longer used as refrigerants from the viewpoint of protecting the global environment, and alternative CFCs are used.

In FIG. 1, a heat pump cycle is schematically shown by taking a general air conditioner as an example, and the apparatus according to the present invention is shown in a cross-sectional view so that the inside thereof can be seen. FIG. 1 (a) shows that the direction of the fluid flow during cooling is counterclockwise. FIG. 1 (b) shows that the direction of the fluid flow during heating is clockwise.

In terms of cooling, the heat pump cycle includes four components: a compression unit 83, a condensation unit (outdoor unit 84), an expansion unit 81, and an evaporation unit (indoor unit 82). The fluid circulates in the sealed piping that connects these components. The arrows in FIGS. 1 (a) and 1 (b) indicate the direction of fluid flow.

Shows. Dashed arrows indicate the transfer of heat between indoors and outdoors. LT is low temperature and HT is high temperature.

In FIG. 1, a liquefaction promoting device 1 suitable for a heat pump system in a data center is installed on a pipe connecting the outdoor unit 84 and the expansion unit 81. The location where the liquefaction accelerator 1 suitable for the heat pump system of the data center is installed may be any position on the piping of the heat pump cycle. The installation position in FIG. 1 is an example.

In FIGS. 1 (a) and 1 (b), an upper three-way valve 42 and a lower three-way valve 43 are provided on the piping of the heat pump cycle, and they are an upper solenoid valve or an upper electric valve 44, a lower solenoid valve or a lower electric valve, respectively. Switching is performed by the valve 45. The switching between the two valves is performed by the control device 58, and as a result, whether the fluid in the pipe passes through the bypass pipe 40, the upper pipe body 60, the inside of the cylindrical housing, and the lower pipe body 70. It is possible to choose alternatives.
A three-way valve is a valve that has fluid inlets and outlets in three directions. Also called a three-way valve.
A solenoid valve has a mechanism to open and close a valve by moving an iron piece called a plunger by using the magnetic force of an electromagnet (solenoid). Also called a solenoid valve or solenoid valve.
An electric valve opens and closes a valve with an electric motor.

An upper temperature sensor 52, an upper flow rate sensor 54 and / and an upper pressure sensor 56 are provided on a pipe (main pipe before branching) near the upper three-way valve 42. Further, a lower temperature sensor 53, a lower flow rate sensor 55 and / and a lower pressure sensor 57 are provided on a pipe (main pipe before branching) near the lower three-way valve 43.
The upper temperature sensor 52 and the lower temperature sensor 53 measure the temperature of the fluid inside the pipe and send the measurement signal to the control device 58.
The upper flow rate sensor 54 and the lower flow rate sensor 55 measure the flow rate of the fluid inside the pipe and send the measurement signal to the control device 58.
The upper pressure sensor 56 and the lower pressure sensor 57 measure the pressure of the fluid inside the pipe and send the measurement signal to the control device 58.
An outdoor unit / compression unit temperature sensor 152, an outdoor unit / compression unit flow sensor 154 and / and an outdoor unit / compression unit pressure sensor 156 are provided on the piping between the outdoor unit 84 and the compression unit 83. .. Further, on the piping between the indoor unit 82 and the compression unit 83, a temperature sensor 153 between the indoor unit and the compression unit, a flow sensor 155 between the indoor unit and the compression unit, and / and a pressure sensor 157 between the indoor unit and the compression unit are placed. It will be provided.
The outdoor unit / compression unit temperature sensor 152 and the indoor unit / compression unit temperature sensor 153 measure the temperature of the fluid inside the pipe and send the measurement signal to the control device 58.
The outdoor unit / compression unit flow rate sensor 154 and the indoor unit / compression unit flow rate sensor 155 measure the flow rate of the fluid inside the pipe and send the measurement signal to the control device 58.
The outdoor unit / compression unit pressure sensor 156 and the indoor unit / compression unit pressure sensor 157 measure the pressure of the fluid inside the pipe and send the measurement signal to the control device 58.
By writing "or / and" here, it means that any one of them or a combination of a plurality of selected ones can be used.

Further, the compression unit 83 constituting the heat pump cycle has a motor 83a as a power source thereof, and a power meter 83b is installed in the power line supplied to the motor 83a. The output signal of the power meter 83b is sent to the control device 58.
The control device 58 includes the above-mentioned upper temperature sensor 52, lower temperature sensor 53, upper flow sensor 54, lower flow sensor 55, upper pressure sensor 56, lower pressure sensor 57, outdoor unit / compression unit temperature sensor 152, indoor unit / Temperature sensor between compression section 153, Flow sensor between outdoor unit and compression section 154, Flow sensor between indoor unit and compression section 155, Pressure sensor between outdoor unit and compression section 156, Pressure sensor between indoor unit and compression section 157, Power meter 83b Based on the measurement signal from any of the above, or a combination thereof, the upper and lower valves (upper electromagnetic valve or upper electric valve 44, lower electromagnetic valve or lower electric valve 45) are simultaneously controlled to control the fluid in the pipe. Switch the flow.

As a result, the fluid in the pipe passes from the upper three-way valve 42 to the upper pipe body 60, the inside of the cylindrical housing, and the lower pipe body 70 during cooling as shown in FIG. 1 (a), and reaches the lower three-way valve 43. Switching is realized in which an alternative choice of whether to take a route to reach or a route from the upper three-way valve 42 to the lower three-way valve 43 through the bypass pipe 40 is realized.
During heating as shown in FIG. 1 (b), the lower three-way valve 43 passes through the lower pipe body 70, the inside of the cylindrical housing, the upper pipe body 60, and the path to the upper three-way valve, or the lower three-way valve. Switching is realized in which the route from 43 to the upper three-way valve 42 through the bypass pipe 40 is selectively selected.

As a control method for simultaneously controlling the upper electromagnetic valve or the upper electric valve 44, the lower electromagnetic valve or the lower electric valve 45 by the control device 58, as described above, the measurement signals of the temperature sensor, the flow rate sensor, the pressure sensor, and the power meter are used. In addition to the control method of monitoring and controlling based on the change, it is also possible to perform planned control.
For example, when the liquefaction accelerator 1 suitable for the heat pump system of this data center is first installed, the bypass pipe 40 is passed through the bypass pipe 40 for a predetermined period (one day, one week, one month, etc.). After that, it is passed through the upper tube body 60 and the lower tube body 70 for the next predetermined period (similarly, one day, one week, one month, etc.). Then, during those operations, it is possible to analyze the measurement signal of the power meter 83b and compare how much the power consumption differs between the two cases.

If the heat pump system is a gas heapon (power of the compressor is a gas engine), the same energy consumption can be achieved by installing a flow meter of fuel gas supplied to the gas engine instead of the power meter 83b. Can be measured.

≪Cycle during indoor cooling≫
In the indoor cooling cycle of FIG. 1A, the compression unit 83 includes a compressor for compressing the low-pressure gas refrigerant in the closed container. In the closed container containing the compressor, an oil reservoir (bottom part in the figure) for storing refrigerating machine oil (compressor oil) is usually provided. The gaseous refrigerant is compressed into a high pressure and higher temperature gas. This gaseous refrigerant is mixed with the refrigerating machine oil and then discharged from the compression unit 83 to the condensing unit (outdoor unit 84). The condensing part includes a capacitor. During cooling, the outdoor unit 84 exchanges heat as a condensing unit. The high-temperature and high-pressure gas fluid that has flowed into the condensing portion is condensed by releasing heat to the outside to become a low-temperature liquid fluid. This liquid fluid is ideally a liquid refrigerant in which refrigerating machine oil is dissolved (or uniformly mixed).

However, when the refrigerant changes from a gas to a liquid in the condensing unit (outdoor unit 84), a part of the refrigerating machine oil may separate without being dissolved (uniformly mixed) in the refrigerant. In addition, the oil phase of the fused refrigerating machine oil may confine the liquid refrigerant. Further, the refrigerant that has almost passed through the condensing portion (outdoor unit 84) may remain as a high-temperature gas. Due to such a phenomenon, the liquid fluid flowing out from the condensing unit (outdoor unit 84) may include the separated refrigerating machine oil, the liquid refrigerant captured in the oil phase of the refrigerating machine oil, and / or the gaseous refrigerant.

The separated refrigerating machine oil is said to reduce the efficiency of heat exchange because it stays in various parts of the heat exchanger during heat exchange in the condensing unit (outdoor unit 84). Using the liquefaction promoting device 1 suitable for the heat pump system of the data center according to the present invention, the upper pipe body 60, the inside of the cylindrical housing, and the lower pipe body 70 pass between the upper three-way valve 42 and the lower three-way valve 43. When controlling to do so, the fluid passes through the cylindrical housing, and as will be described later, the refrigerating machine oil and the refrigerant are mixed in a finely divided state due to the shearing effect, so that the fluid is repeatedly heat pumped. By circulating the inside, the refrigerating machine oil does not stay in the heat exchanger, and the effect of increasing the efficiency of heat exchange is expected.

At the time of indoor cooling shown in FIG. 1 (a), the liquefaction promoting device 1 suitable for the heat pump system of the data center of the present invention is inserted between the condensing unit (outdoor unit 84) and the expanding unit 81. The upper tube 60 of the liquefaction promoting device 1 suitable for the heat pump system of the data center is connected to the outlet side of the condensing portion which is the outdoor unit 84, and the lower tube 70 of the liquefaction promoting device 1 is connected to the inlet side of the expanding portion 81. It is connected. When the fluid flowing out of the condensing portion 84 is guided to the upper tubular body 60 by the upper three-way valve 42, a sufficient shearing effect is given inside the cylindrical housing and the fluid is mixed. As a result, the separated refrigerating machine oil is uniformly mixed with the liquid refrigerant, the liquid solvent captured in the oil phase of the refrigerating machine oil is released, and the temperature of the remaining gaseous refrigerant drops to become the liquid refrigerant. After that, the fluid flowing out of the liquefaction promoting device 1 is sent to the expansion unit 81.

The expansion portion 81 includes an expansion valve, a capillary tube, or the like. The low-temperature and high-pressure liquid fluid becomes a low-temperature and even lower-temperature liquid by being passed through a narrow hole or a pipe. After that, this fluid is sent to the evaporation unit (indoor unit 82). The evaporation unit is equipped with an evaporator. During indoor cooling shown in FIG. 1 (a), the indoor unit 82 exchanges heat as an evaporation unit. The low-temperature low-pressure liquid fluid that has flowed into the evaporation section evaporates by absorbing heat from the outside and becomes a high-temperature gas fluid. This cools the air in the room. After that, the gas fluid is returned to the compression unit 83.

Even when heat exchange is performed in the indoor unit 82 (evaporation unit), the refrigerating machine oil and the refrigerant are mixed in a finely divided state due to the shearing effect as described above, so that the efficiency of heat exchange can be improved. There is expected.

≪Cycle during room heating≫
In the cycle during indoor heating in FIG. 1 (b), the circulation direction of the fluid is opposite to that during cooling in FIG. 1 (a). Well-known valves (eg, four-way valves) are used in heat pump systems to switch the direction of fluid circulation (illustration and description omitted). During heating, the high-temperature and high-pressure gas fluid discharged from the compression unit 83 is sent to the indoor unit 82 that exchanges heat as a condensing unit. The high-temperature and high-pressure gas fluid that has flowed into the condensing unit (indoor unit 82) is condensed by releasing heat to the outside to become a low-temperature liquid fluid. This warms the air in the room.

Here, when the refrigerant changes from gas to liquid in the condensing section (indoor unit 82), the liquid fluid flowing out of the condensing section is the separated refrigerating machine oil and refrigerating machine oil, as in the cooling cycle of FIG. 1 (a). May contain liquid and / or gaseous refrigerants trapped in the oil phase of. At the time of heating, the liquid fluid flowing out from the condensing unit (indoor unit 82) is further sent to the expansion unit 81 to become a low-pressure and lower-temperature liquid. Even after passing through the expansion portion 81, the separated refrigerating machine oil, the captured liquid refrigerant and / or the gaseous refrigerant may remain.
When the refrigerating machine oil and the refrigerant are mixed in a miniaturized state by the shearing effect as described above, it is expected that the efficiency of heat exchange will be improved.

At the time of indoor heating shown in FIG. 1 (b), the liquefaction promoting device 1 suitable for the heat pump system of the data center of the present invention is installed between the expansion unit 81 and the evaporation unit (outdoor unit 84). The lower pipe body 70 of the liquefaction promoting device 1 is connected to the outlet side of the expansion portion 81, and the upper pipe body 60 of the liquefaction promoting device 1 is connected to the inlet side of the evaporation unit which is the outdoor unit 84. The fluid flowing out of the expansion unit 81 is sufficiently uniformly mixed in the liquefaction promoting device 1. The separated refrigerating machine oil is uniformly mixed with the liquid refrigerant, the liquid solvent captured in the oil phase of the refrigerating machine oil is released, and the temperature of the remaining gaseous refrigerant drops to become the liquid refrigerant. After that, the fluid flowing out from the liquefaction promoting device 1 suitable for the heat pump system of the data center is sent to the evaporation unit (outdoor unit 84).

During the indoor heating shown in FIG. 1 (b), the outdoor unit 84 exchanges heat as an evaporation unit. The low-temperature low-pressure liquid fluid that has flowed into the evaporation section evaporates by absorbing heat from the outside and becomes a high-temperature gas fluid. After that, the gas fluid is returned to the compression unit 83. When the refrigerating machine oil and the refrigerant are mixed in a state of being miniaturized by the shearing effect as described above, it is expected that the efficiency of heat exchange will be improved even in the heat exchange in the outdoor unit during heating.

As shown in FIGS. 1A and 1B, the liquefaction promoting device 1 suitable for the heat pump system of the data center of the present invention is inserted in the path of the piping constituting the heat pump system. Since the actual pipe is formed by connecting a plurality of pipe members, for example, by removing one pipe member and replacing and connecting with the liquefaction promoting device 1 of the present invention, the liquefaction promoting device 1 can be easily attached. be able to. As shown in FIGS. 1 (a) and 1 (b), for example, it can be installed in an outdoor pipe near the outdoor unit. At this time, the pipe is made so as to draw a smooth curve of an appropriate size so that the fluid in the pipe can move smoothly.

In FIGS. 1A and 1B described above, an example in which the liquefaction promoting device 1 of the present invention is applied to the basic form of the heat pump system is shown. There are many applications in an actual heat pump system. The liquefaction promoting device 1 of the present invention is also applicable to a heat pump system in which various components are added to the basic form. For example, even in a system provided with a gas-liquid separator that separates a refrigerant in a gas-liquid two-phase state, a liquefaction promoting device 1 suitable for the heat pump system of the data center of the present invention can be used in combination. Further, for example, even in a system provided with an ejector and a gas-liquid separator in place of the expansion portion, the liquefaction promoting device 1 suitable for the heat pump system of the data center of the present invention can be used in combination.

FIG. 2 is a cross-sectional view of a cylindrical housing portion of a liquefaction promoting device suitable for the heat pump system of the data center of the present invention. Further, FIG. 3 is a diagram illustrating the appearance of the cylindrical housing portion of the liquefaction promoting device suitable for the heat pump system of the data center of the present invention. The cylindrical housing portion of the liquefaction promoting device 1 suitable for the heat pump system of the data center has the housing 10. The housing 10 has a cylindrical body portion 11 having a central axis in the vertical direction, a hemispherical upper end plate 12 that closes the upper end side of the body portion, and a hemispherical lower end plate 13 that closes the lower end side of the body portion. Equipped with. Here, the liquefaction accelerator suitable for the heat pump system of the data center of the present invention passes a fluid containing a refrigerant and refrigerating machine oil at a pressure of about 0.2 megapascals to 10 megapascals, so that the pressure can be increased accordingly. It needs to be a structure that can withstand. Since the fluid in the liquefaction promoting device suitable for the heat pump system of the data center of the present invention is a pressure fluid discharged from the compressor at a predetermined pressure, it can be said that the housing 10 is also a pressure vessel. The "end plate" in a pressure vessel generally means a hemispherical lid member that closes the upper and lower ends of a cylindrical pressure vessel. The cross section of the upper end plate 12 and the lower end plate 13 shown in FIG. 3 is a semicircle with a central angle of 180 degrees, and the radius thereof is equal to the radius of the cylindrical body portion 11.

Two tubes, an upper tube 60 and a lower tube 70, are provided for the inflow or outflow of fluid into the housing 10. FIG. 3D shows the appearance of the liquefaction promoting device 1 as viewed from the side surface. It shows that the upper tube 60 is provided through the upper end plate 12 and the lower tube 70 is provided through the lower end plate 13. When the liquefaction accelerator 1 suitable for the heat pump system of the data center is inserted into the piping path of the heat pump system, one of the two pipe bodies, the upper pipe body 60 and the lower pipe body 70, is inserted at the insertion point. Connect to the end of the pipe and connect the other pipe to the end of the other pipe. As described with reference to FIGS. 1 (a) and 1 (b) described above, the direction of fluid circulation is opposite between cooling and heating. Therefore, the inlet at the time of cooling of the liquefaction promoting device 1 suitable for the heat pump system of the data center becomes the outlet at the time of heating, and the outlet at the time of cooling becomes the inlet at the time of heating. The effect of the liquefaction accelerator suitable for the heat pump system of the data center was demonstrated even during heating in which the circulation direction is reversed. Therefore, even if the cooling and heating of the air conditioner are switched, it is not necessary to change the mounting state of the liquefaction promoting device suitable for the heat pump system of the data center of the present invention.

The upper pipe body 60 serves as an inlet during cooling and an outlet during heating. Although the upper portion of the upper tubular body 60 is not shown in FIG. 3, it can be connected to an appropriate pipe of the heat pump system. Although the mounting state of the liquefaction promoting device 1 is not changed between cooling and heating, the fluid circulation direction is opposite, so that the upper tube 60 has a condensed portion (outdoor) during cooling shown in FIG. It is connected to the outlet side of the machine) and is connected to the inlet side of the evaporation unit (outdoor unit) during heating shown in FIG.

The upper tubular body 60 penetrates the upper end plate 12 in the vertical direction at a position away from the central axis. The upper tubular body 60 extends downward to the vicinity of the upper end of the body portion 11 in the housing 10, and the lower end 60a thereof opens downward. As shown in FIG. 2, it is preferable that the edge of the opening of the lower end 60a of the upper tubular body 60 is inclined so that the central axis side is low and the peripheral edge side is high. This tilt forms a good flow of fluid containing refrigerating machine oil and refrigerant, causing the large diameter spiral spring 20 and the small diameter spiral spring 30, that is, two large and small springs to swing and vibrate, due to the shear effect. It is for mixing fluids and, by extension, promoting liquefaction.

The lower pipe body 70 serves as an outlet during cooling and an inlet during heating. Although the lower portion of the lower pipe body 70 is not shown in FIGS. 2 and 3, it can be connected to an appropriate pipe of the heat pump system. The lower tube body 70 penetrates the lower end plate 13 in the vertical direction on the central axis. The lower tubular body 70 extends upward along the central axis to the vicinity of the upper end of the body portion 11 in the housing 10, and the upper end 70a thereof opens upward.

Further, a large-diameter spiral spring 20 is installed in the vicinity of the inner wall 1 mm to 10 mm away from the inner wall of the body portion 11. The central axis of the large-diameter spiral spring 20 is provided so as to coincide with the central axis of the body portion 11. The large-diameter spiral spring 20 is attached to the inner wall of the body portion 11 (for example, by welding) only at four locations of the spring mounting portions 21, 22, 23, 24, that is, only the upper end portion and the lower end portion of the large-diameter spiral spring 20. The fixed and non-fixed middle part can swing and vibrate (up and down). Here, the swing is to move in a direction perpendicular to the direction of expansion and contraction of the spring. It is also possible to have an example in which the upper end portion and the lower end portion are attached at two locations, three locations, and four locations.
As will be described in detail with reference to FIG. 4, the large-diameter spiral spring 20 is a spiral spring having an unequal pitch in which the pitch of the portion near the spring mounting portion is narrow and the pitch of the unfixed intermediate portion is widened. That is, it is preferable that it is wide → narrow → wide as shown in FIG. 8 (a), or narrow → wide → narrow as shown in FIG. 8 (b).

The materials of each component of the liquefaction promoting device of the present invention, that is, the housing 10, the upper pipe body 60, the lower pipe body 70, the large-diameter spiral spring 20, and the small-diameter spiral spring 30, can be used for piping of the heat pump system. Any material may be used, and without particular limitation, an appropriate material can be used for the pressure vessel. For example, it is made of steel.
The small-diameter spiral spring 30 is fixed to the outer wall of the lower tubular body 70 (for example, by welding) only at four mounting portions 31, 32, 33, 34, that is, only the upper end and the lower end of the small-diameter spiral spring 30. The middle part, which is not fixed, can swing and vibrate (up and down). It is also possible to have an example in which the upper end portion and the lower end portion are attached at two locations, three locations, and four locations. The small-diameter spiral spring 30 is preferably a spiral spring having an unequal pitch in which the pitch of the portion close to the spring mounting portion is narrow and the pitch of the unfixed intermediate portion is widened.

4 (a) is a plan view of the large-diameter spiral spring 20 shown in FIG. 2, and FIG. 4 (b) is a sectional view taken along the line DD of FIG. 4 (a). The large-diameter spiral spring 20 is an unequal pitch spiral spring. The pitch gradually increases from the end to the middle. Now, the length direction of the large-diameter spiral spring in the expansion / contraction direction will be described by dividing it into nine regions of p1, p2, p3, ..., And p9. The pitch is considered to be the length of the gap created between the winding constituting the large-diameter spiral spring and the winding next to it. P1 and p9 have a pitch of 0.8 mm, and p2 and p8 have a pitch of 1.2 mm. p3 and p7 can have a pitch of 1.6 mm, p4 and p6 can have a pitch of 2.0 mm, and p5 can have a pitch of 2.5 mm. Looking at the size of the pitch, it is vertically symmetrical. That is, if the pitch of p1 is expressed as p1, the pitch of p2 is expressed as p2, ..., And the pitch of p9 is expressed as p9, then p1 <p2 <p3 <p4 <p5> p6> p7> p8> p9, and p1 = p9. , P2 = p8, p3 = p7, p4 = p6.

The pitch in each of the plurality of regions (p1, p2, p3, ...) Is constant, and not only the pitch of each region has a relationship of p1 <p2 <p3 <..., but also the inside of each region can be seen. The adjacent spacing between the windings of each spiral spring may be gradually changed.

When a fluid containing refrigerating machine oil and a refrigerant flows into the liquefaction promoting device 1, the large-diameter spiral spring 20 swings and vibrates, and exerts a shearing effect on the fluid. In addition, the surface of the spiral spring has various surfaces, and the unevenness itself exerts a shearing effect on the fluid. As a result, the fluid is made finer and more uniform, and liquefaction is promoted. The large-diameter spiral spring 20 is provided at a distance of 1 mm to 10 mm from the inner wall of the body portion 11 of the housing 10. Then, at the upper end and the lower end thereof, it is only fixed to the housing 10, and the other parts can freely swing and vibrate.

It is desirable that the small diameter spiral spring 30 shown in FIG. 2 is also an unequal pitch spiral spring. Similar to the large-diameter spiral spring 20, the pitch can be wide->narrow-> wide or narrow->wide-> narrow from the top.
The upper end of the small-diameter spiral spring 30 is fixed to the upper end of the lower tubular body 70, and the lower end of the small-diameter spiral spring 30 is fixed to the outer wall of the lower tubular body 70. The fixing method is, for example, by welding.
The small diameter spiral spring 30 is located so as to surround the lower tubular body 70. Therefore, it is possible to swing and vibrate in a region of 1 mm to 30 mm around the lower tubular body 70. The upper end 70a of the lower pipe body 70 may have a shape provided with a flange (flange, flange), for example. Then, the flange-shaped portions can be the spring mounting portions 31 and 32. As the fixing means, welding at a plurality of places, for example, four places can be used. By attaching the small diameter spring 30 to the flange-shaped portion, the small diameter spring 30 can be made to swing and vibrate in a region 1 mm to 30 mm away from the outer wall of the lower tubular body 70.

<Operation when fluid flows in from the upper pipe body 60>
When a fluid flows in from above through the upper tubular body 60 that opens at a position away from the central axis of the housing 10, the following fluid flow is generated. The inflowing fluid goes straight downward and then is turned upward (U-turn) by the lower end plate 13. This is realized by the shape of the lower end plate 13 being a hemispherical shape. The fluid that has changed direction goes straight upward and then is turned downward (U-turn) by the upper end plate 12. This is realized by the shape of the upper end plate 12 being a hemispherical shape. As a result, a strong vertical flow is formed, and as a result, the fluid is greatly agitated over the entire internal space of the housing 10. Further, the edge of the opening of the upper tube 60 located away from the central axis of the housing 10 is inclined so that the central axis side is low and the peripheral edge side is high, so that a flow traveling straight downward is formed. It will be easier. As a result, a vertical flow is smoothly generated. This upper and lower fluid flow causes the large-diameter spiral spring 20 and the small-diameter spiral spring 30 to swing and vibrate. Effective agitation of the fluid is realized by the synergistic effect of the fluid colliding with the windings of the large-diameter spiral spring 20 and the small-diameter spiral spring and the swing and vibration of the two spiral springs. After being sufficiently agitated, the fluid flows downward through the lower tubular body 70.

<Operation when fluid flows in from the lower tube 70>
When a fluid flows in from below through the lower tube 70 located on the central axis of the housing 10, the following fluid flow is generated. The fluid discharged from the opening of the upper end 70a of the lower tubular body 70 travels straight upward and then is turned downward (U-turn) by the upper end plate 12. This is realized by the shape of the upper end plate 12 being a hemispherical shape. Further, the fluid traveling straight downward is turned upward (U-turn) by the lower end plate 13. This is realized by the shape of the lower end plate 13 being a hemispherical shape. This creates a strong vertical fluid flow. As a result, the fluid is greatly agitated over the entire internal space of the housing 10. Further, the fluid flow in the vertical direction collides with the upper tube 60 located away from the central axis and the lower tube 70 located on the central axis when the direction is changed in the upper part of the housing 10. It branches into two and each produces a flow. A plurality of flows are formed one after another around the upper pipe body 60 and the lower pipe body 70. Further, a large-diameter spiral spring having a winding that can swing and vibrate due to friction and collision with a large-diameter spiral spring 20 provided on the inner surface of the body portion 11 and friction and collision with a small-diameter spiral spring. 20. The small-diameter spiral spring 30 causes vibration and vibration in the local area where it is subjected to friction or collision, respectively. In addition to swinging and vibration, the large-diameter spiral spring 20 and the small-diameter spiral spring each have a large number of uneven shapes, which also exert a shearing force on the fluid. As a result, the fluid is made finer and more uniform. The liquefaction promoting device 1 of the present invention realizes effective fluid agitation. After being sufficiently agitated, the fluid flows upward through the upper tubular body 60.

<Action / mechanism>
It is thought that the action and mechanism can be explained by the overtone resonance (scaling resonance) of sound.
When a fluid of several megapascals flows into the liquefaction promoting device according to the present invention, an impact is applied to the spring. Then, the impact causes the spring to vibrate and swing. By transmitting the vibration and fluctuation, sound (not limited to the audible range, including the possibility of lower sound or higher sound) is generated. Due to the continuous inflow of fluid, this noise also continues to occur.
On the other hand, when the refrigerant and the refrigerating machine oil are mixed, a sound is also generated when the clusters of molecules collide with each other. These two sounds can be in a harmonic relationship. The harmonics (harmonics) of the sound generated by the vibration and swing of the spring are harmonic resonance (scaling resonance) when the clusters of the refrigerant and refrigerating machine oil molecules collide with each other. As a result, the fluid is mixed and agitated, and eventually liquefaction is promoted.
Here, scaling resonance is a phenomenon of resonance in harmonics (harmonics) several tens of octaves higher. This is the concept used in "Protein Music" (Chikuma Primer Books by Yoichi Fukagawa).
Resonance and resonance are similar concepts, but in the present specification, they will be considered separately. For example, when two strings fixed to the same wooden frame (solid) vibrate one, the other also vibrates. In this case, the vibration is transmitted through a solid called a wooden frame, so that it is a resonance. On the other hand, it is resonance that the sound is transmitted through water, air, etc. (fluid) and vibrates as a result.
In the case of the liquefaction promoting device according to the present invention, vibration is transmitted from the spring to the refrigerant molecules and the refrigerating machine oil molecules via the fluid. Therefore, it should be called resonance. Therefore, it is considered that the harmonic resonance or scaling resonance of the sound is functioning.
Focusing on the macroscopic behavior of the fluid in the liquefaction promoting device according to the present invention, the fluid acts to give an impact to the spring by its high pressure to vibrate and swing the spring. On the other hand, focusing on the microscopic behavior of the fluid, the refrigerant and refrigerating machine oil clusters (a mass of several molecules stuck together) contained in the fluid are forced to reduce the size of the clusters by harmonic resonance or scaling resonance. Receive. As a result, under the shearing effect, the refrigerant and refrigerating machine oil make the cluster smaller and perform uniform mixing.

<Effect>
At a pressure of 0.2 megapascals to 10 megapascals, a fluid containing a refrigerant and refrigerating machine oil is passed through the liquefaction promoting device according to the present invention. As a result, the spring of the liquefaction promoting device according to the present invention receives an impact and causes vibration and rocking. This vibration and oscillation causes waves of various frequencies. Waves containing many harmonics are generated. If this wave is regarded as a sound wave, many harmonics can be regarded as many overtones. These harmonics act on the refrigerant and refrigerating machine oil clusters at the molecular level, resulting in a shearing effect that reduces the size of the mass. At this time, it is considered that the phenomenon of resonance due to harmonics or resonance due to overtones occurs. That is, in the spring, harmonic resonances or harmonic resonances at the molecular level also occur continuously in response to vibrations and oscillations. As a result, the shearing effect is evenly distributed throughout the refrigerant and refrigerating machine oil.
In this way, the refrigerant and the refrigerating machine oil are uniformly mixed.
Due to the shearing effect of the liquefaction accelerator, the refrigerant and refrigerating machine oil are uniformly mixed. Then, the heat exchange efficiency of CFC substitutes can be improved. The liquefaction promoting device of the present invention can be effective regardless of the types of the refrigerant and the refrigerating machine oil used in the heat pump cycle. In particular, by applying it to an alternative chlorofluorocarbon, which is inferior in compatibility with refrigerating machine oil as compared with a specific chlorofluorocarbon, the heat exchange efficiency of the alternative chlorofluorocarbon can be significantly improved.

<Power reduction, energy reduction>
The device of the present invention is a heat pump that exchanges heat, such as a heat pump that uses electricity as energy and a heat pump that uses gas as energy (an engine that uses gas as fuel instead of a motor in FIG. 1). It can be widely used in heat pumps that circulate a refrigerant and refrigerating machine oil, and brings about an energy reduction effect.

<< Hardware configuration of control unit 58 >>
FIG. 17 is a block diagram showing a hardware configuration of the control unit 58 shown in FIG. The control unit 58 has temperature sensors 52, 53, 152, 153, flow sensors 54, 55, 154, 155, pressure sensors 56, 57, 156, 157, a power meter 83b, and an outside temperature sensor on the bus of the microprocessor 58a. 51, an electromagnetic valve or an electric valve drive circuit 44a, 45a, a storage circuit 58b, and a communication circuit 58c are connected.
Here, the microprocessor is also called a microcomputer, a microprocessing unit, a CPU, or the like, and is an integrated circuit that executes processing, calculation, and the like according to a computer program.

The temperature sensors 52, 53, 152, and 153 are an upper temperature sensor 52, a lower temperature sensor 53, an outdoor unit / compression unit temperature sensor 152, and an indoor unit / compression unit temperature sensor 153 shown in FIG.
The flow rate sensors 54, 55, 154, and 155 are an upper flow rate sensor 54, a lower flow rate sensor 55, an outdoor unit / compression unit temperature sensor 152, and an indoor unit / compression unit temperature sensor 153 shown in FIG.
The pressure sensors 56, 57, 156, and 157 are an upper pressure sensor 56, a lower pressure sensor 57, an outdoor unit / compression unit pressure sensor 156, and an indoor unit / compression unit pressure sensor 153 shown in FIG.
Although the outside air temperature sensor 51 is not shown in FIG. 1, a temperature sensor is installed at a position in contact with the outside of the liquefaction promoting device 1 suitable for the heat pump system of the data center according to the present invention, and the output signal thereof is a microprocessor. It can be configured to be delivered to 58a.
The solenoid valve or electric valve drive circuits 44a and 45a generate a drive signal for driving the upper solenoid valve or electric valve 42, the lower solenoid valve or the electric valve 43 based on the instruction of the microprocessor 58a, and generate a drive signal to the valve. It is a circuit that drives them by sending the electrical signals.

By the action of the communication circuit 58c, an input signal from the outside is received and passed to the microprocessor 58a. It also functions to communicate from the microprocessor 58a to an external device (for example, the terminal device of the administrator of the heat pump system).

≪Effect confirmation process at the time of installation≫
The installation effect confirmation process shown in FIG. 18 is a process for confirming the effect before and after installing a liquefaction promoting device suitable for the heat pump system of the data center according to the present invention. It is the microprocessor 58a that performs this process.
When installing a liquefaction promoting device suitable for the heat pump system of the data center according to the present invention in an existing heat pump system, the operation of the heat pump system is temporarily stopped to drain the refrigerant and refrigerating machine oil inside the piping. Then, a liquefaction promoting device suitable for the heat pump system of the data center according to the present invention is installed in the middle of piping of the heat pump system (for example, near an outdoor unit). Then, the refrigerant and the refrigerating machine oil are filled. In this way, when the heat pump system is ready to be restarted, the program for confirming the effect at the time of installation shown in FIG. 18 is executed. This program is started by the microprocessor 58a reading and executing the program file stored in the storage circuit 58b in advance.

At the time of starting this program, for example, the microprocessor 58a can display the menu display on a liquid crystal display device (not shown), and the operator can be configured to start the program by operating the menu.
Also, from an external device (for example, the terminal device of the operator of the heat pump system), access the microprocessor 58a by communication (wireless communication, PHS communication, Internet communication, etc.), select the program, and execute it. You may do it.

When the installation effect confirmation process shown in FIG. 18 starts, first, whether the bypass pipe 40 is enabled, that is, the piping of the heat pump system is performed by the action of the upper solenoid valve or the electric valve 42, the lower solenoid valve or the electric valve 43. It is determined whether or not the fluid in which the refrigerant and the refrigerating machine oil circulating in the valve are mixed passes through the bypass 40 (step 1801).
Actually, the solenoid valve or the electric valve drive circuits 44a and 45a have information describing the state of the upper solenoid valve or the electric valve 42, the lower solenoid valve or the electric valve 43, respectively, and the microprocessor has the information for the information. With the access of 58a, the determination of step 1801 can be made.

If the bypass 40 is in a functioning state, it is determined to be YES in step 1801 and the process proceeds to step 1803. If the bypass 40 is not functioning, a process of switching to the bypass tube is performed (step 1802), and then the process proceeds to step 1803.
Here, in the process of switching to the bypass tube, the solenoid valve or the electric valve drive circuits 44a and 45a generate a drive signal in response to the command sent by the microprocessor 58a, and the upper solenoid valve or the electric valve 42 and the lower solenoid are generated. It is realized by operating each valve based on sending to the valve or the electric valve 43.

In step 1803, the microprocessor 58a outputs an "operable signal" indicating that the heat pump system has become operable to the outside. The output to the outside is sent to an external device, that is, a terminal device of the operator of the heat pump system by the communication circuit 58c. Upon receiving this signal, the operator of the heat pump system resumes the operation of the heat pump system. In this state, the fluid in which the refrigerant circulating in the heat pump system and the refrigerating machine oil are mixed passes through the bypass pipe 40, and therefore does not pass through the inside of the cylindrical housing. Therefore, the refrigerant and the refrigerating machine oil circulate without being mixed, sheared, or the like.

In this state, the output of each sensor (temperature sensor, flow sensor, pressure sensor, wattmeter) is recorded and analyzed by the microprocessor 58a, and the result is stored in the storage circuit 58b (step 1804). For example, data can be measured and saved every 6 seconds. The data of the stored measurement signal may be output to an external device when it has accumulated to some extent so as not to exceed the storage capacity of the storage circuit 58b.
Step 1804 and step 1805 are repeatedly executed until a predetermined time elapses, for example, one day, one week, one month, and the like, and the recording and analysis of the measurement signal are repeated.

When the predetermined time has elapsed (YES in step 1805), the valve is switched to switch to the flow to the upper pipe body and the lower pipe body (step 1806). This valve switching is performed by a command sent by the microprocessor 58a to the solenoid valve or the electric valve drive circuits 44a and 45a, which causes the drive circuit to generate a drive signal and send a signal to the respective solenoid valve or the electric valve. To. As a result, the mixed fluid of the refrigerant and the refrigerating machine oil circulating in the heat pump pipe repeatedly passes through the upper pipe body 60, the inside of the cylindrical housing, and the lower pipe body 70, and is mixed and sheared in the heat pump system. It has the effect of increasing the heat exchange efficiency of the heat exchanger.

By step 1807 and step 1808, the output of each sensor (temperature sensor, flow sensor, pressure sensor, wattmeter) is micron until a predetermined time (one day, one week, one month, etc.) has passed. The processor 58a records and analyzes and stores the result in the storage circuit 58b (step 1807). For example, the data can be saved every 6 seconds. The data of the stored measurement signal may be output to an external device when it has accumulated to some extent so as not to exceed the storage capacity of the storage circuit 58b.

When a predetermined time has passed (YES in step 1808), the recording / analysis result is output to an external device (step 1809). For example, when the terminal device of the operator of the heat pump system receives the recording / analysis result, the operator compares the outside temperature and the power consumption under similar time conditions to obtain the data of the present invention. It is possible to confirm the effect of installing a liquefaction promotion device suitable for the heat pump system of the center.

≪Emergency evacuation processing≫
The emergency evacuation process shown in the flowchart in FIG. 19 monitors the output of each sensor and thereby switches to the bypass pipe 40. Performing this process as a normal process in case of an emergency that may occur is suitable as a liquefaction accelerator suitable for a heat pump system in a data center. This is because the data center handles a large amount of important customer data, and if important data should be lost, great damage will occur.

This emergency evacuation process is performed when the heat pump system shears and mixes the mixed fluid using the upper tube body 60, the inside of the cylindrical housing, and the lower tube body 70.
First, the valve position is confirmed (step 1901). This process can be done by the microprocessor 58a inquiring the solenoid valve or the electric valve drive circuits 44a, 45a about the valve status.
If normal, that is, the mixed fluid flows through the upper tube, the inside of the cylindrical housing, and the lower tube, the process proceeds to step 1904. If it is not normal, the valve position is corrected (step 1903) and the process proceeds to step 1904. The correction of the valve position is made by receiving a command from the microprocessor 58a to the solenoid valve or the electric valve drive circuits 44a and 45a, the drive circuit generating a drive signal, and sending the signal to each valve. To.

In step 1904, the output of each sensor (temperature sensor, flow sensor, pressure sensor, wattmeter) is measured, for example, every 6 seconds, the microprocessor 58a records and analyzes it, and the result is stored in the storage circuit 58b. (Step 1904). The microprocessor 58a analyzes the measurement data and monitors the occurrence of an abnormality. For example, anticipate changes in flow rate and pressure that may occur if the spring inside the cylindrical housing, the upper pipe body, or the lower pipe body is damaged, and continue monitoring in preparation for such a situation. Can be considered.
If no abnormality is found, NO is determined in step 1905, and steps 1904 and 1905 are repeatedly executed.

In the unlikely event that an abnormality is suspected (YES in step 1905), the pipe is switched to the bypass pipe (step 1906). This switching is made by the microprocessor 58a issuing a command to the solenoid valve or the electric valve drive circuits 44a, 45a.
After switching the valve, a report is output (step 1907), and this process is completed. The output of this report informs the terminal equipment of the operator of the heat pump system, and the operator recognizes that the operation of the heat pump system has been switched to the operation without shearing and mixing of the fluid. Because.
Even after this switching, the heat pump system can continue to operate without stopping.

≪Parts replacement process≫
The component replacement process shown in FIG. 20 is a process performed when it becomes necessary to replace a portion of the cylindrical housing. This parts replacement is performed not only when the parts are assumed to be broken, but also when the product life reaches a predetermined period of 3 years, or when a new technology is developed for the cylindrical housing part. It is possible to replace it with a new one.
First, it is determined whether or not the bypass is currently used (step 2001). If the bypass is used, the process proceeds to step 2003. When the bypass is not used, the microprocessor 58a switches to the bypass tube (step 2002) and proceeds to step 2003.

In step 2003, the microprocessor 58a outputs a replaceable signal to the external device. As a result, the heat pump system operator (maintenance contractor) carries out the work of replacing the portion of the cylindrical housing. Then, when the work is completed, the heat pump system operator (maintenance company) notifies the microprocessor 58a to that effect by using an external device. After outputting the replaceable signal in step 2003, the microprocessor 58a continues to wait for the notification of "replacement end" from the external device (NO in step 2004).
When the notification of "replacement completion" is received from the external device, valve switching is executed (step 2005). As a result, the operation of the heat pump system in the state where the mixed fluid in the heat pump system is sheared and mixed is restarted by using the replaced part (cylindrical housing). During the replacement, the heat pump system itself will not be shut down.
When the operation using the new parts is restarted, the process of recording and analyzing the output of each sensor (step 2006) and the process of outputting the report to the external device (step 2007) are performed, and the parts replacement process is completed.

<< Modification example of emergency evacuation >>
In the above-mentioned emergency evacuation process, switching to the bypass tube in the event of an abnormality is executed according to a program pre-assembled by the microprocessor 58a. However, it can be difficult to make a decision with a pre-configured program. Therefore, when it seems that there is an abnormality, a report is output to an external device, and at that time, a specialist such as a maintenance company examines the measurement data before and after that in detail, makes a judgment, and uses a communication circuit. Valve switching may be performed by instructing the microprocessor 58a.
So to speak, it enables remote control. Further, the external device may request the measurement data when necessary, and the microprocessor 58a may output the measurement data in response to the request.

≪How much is included in one housing≫

Is. In particular, the power meter 83b can be made possible by passing a power line supplied to the motor 83a near the control unit 58.
When the power meter 83b is installed away from the control unit 58, the control unit 58 can acquire the measurement signal by performing wireless communication or the like between the power meter 83b and the control unit 58.

In this way, examples of cloud computing and IoT are possible.
