Description

  The present invention relates to a liquid transport device, an adsorption heat pump, and a heat storage system.

  The heat storage device described in Patent Document 1 includes an evaporation condenser that is a pressure reduction system. And this evaporative condenser has a water reservoir (liquid layer) inside.

Unexamined-Japanese-Patent No. 2013-216763

  When the evaporation condenser (pressure reduction vessel) is used as an evaporator, at least a part of the flowing water pipe in which the heat medium flows must be disposed in the liquid phase inside the evaporation condenser. On the other hand, when the evaporation condenser is used as a condenser, at least a part of the flowing water pipe must be disposed in the air layer.

  For this reason, a water reservoir is provided separately from the main body of the evaporative condenser, water is supplied to the evaporative condenser from this water reservoir, and the water level of the evaporative condenser is adjusted by recovering water from the evaporative condenser. There is. Thus, when a water reservoir is provided separately from the evaporative condenser, it is conceivable to pressurize the water (liquid) of the water reservoir to supply water to the evaporative condenser. When pressurizing water, for example, a pressurizing member such as a plunger head may be moved relative to a container in which the water is stored to pressurize the water stored in the container. However, in such a configuration, gas may enter the water from between the pressurizing member and the container.

  An object of the present invention is to suppress entry of gas into a liquid to be transported when transporting the liquid to and from a decompression container whose inside is decompressed.

  A liquid transport apparatus according to a first aspect of the present invention is a container in which a liquid is stored inside and a pressure reducing layer which is reduced in pressure relative to atmospheric pressure in the inside, a reduced pressure container which is reduced in pressure, and the container In the interior of the container so as to divide the communication layer communicating with the portion in which the liquid is stored, the layer of liquid stored in the interior of the container, and the depressurized layer, and increase or decrease the volume of the layer of liquid And a movably provided partition portion.

  According to the above configuration, when the liquid is supplied to the decompression container, the partition part of the liquid transport device is moved to the liquid stored in the container, and the liquid stored in the container is pressurized. The liquid transport device supplies the liquid to the vacuum container. On the other hand, in the case of recovering the liquid from the decompression container, the partition of the liquid transport device is moved to the opposite side to the liquid side stored inside the container, and the part where the liquid is stored inside the container By decompressing the liquid, the liquid transport device recovers the liquid from the vacuum vessel.

  Here, the partition portion movably provided inside the container is disposed so as to separate the liquid layer stored inside the container and the pressure reduction layer decompressed relative to the atmospheric pressure. There is. For this reason, compared with the case where a pressure reduction layer is atmospheric pressure, it is suppressed that a gas entraps into the layer of a liquid from between a container and a partition part.

  In other words, when transporting the liquid to and from the decompression container, it is possible to suppress gas from entering the transported liquid.

  A liquid transport apparatus according to a second aspect of the present invention is the liquid transport apparatus according to the first aspect, wherein the inside of the container is divided into the decompression layer and a layer of gas different from the decompression layer, and It is characterized by comprising: a dividing portion provided so as to be movable in the same direction as the moving direction of the dividing portion; and a connecting portion connecting the dividing portion and the dividing portion.

  According to the above configuration, the dividing portion connected to the dividing portion by the connecting portion divides the decompression layer and the layer of gas different from the decompression layer. Thereby, even if the partition part moves, it can be suppressed that the volume of the pressure reduction layer changes.

  A liquid transport apparatus according to a third aspect of the present invention is the liquid transport apparatus according to the second aspect, wherein the container is provided with a separation part that separates the layer of the gas from the outside of the container. It is characterized by including an increase / decrease member that increases / decreases the pressure of the layer.

  According to the above configuration, the partition member is moved to the liquid side stored inside the container by the increase / decrease members increasing the pressure of the gas layer. Thereby, the liquid transport device supplies the liquid to the decompression container. Further, the decrease and increase members decrease the pressure of the gas layer, whereby the partition moves to the side opposite to the liquid stored in the container. Thereby, the liquid transport device recovers the liquid from the decompression container.

  Thus, the liquid transport device can transport the liquid to and from the decompression container by the increase and decrease members increasing and decreasing the pressure of the gas layer.

  An adsorption type heat pump according to claim 4 of the present invention is an adsorption device provided with an adsorbent which adsorbs an adsorption medium which is steam and desorbs the adsorption medium, and a decompression vessel whose inside is decompressed, and the liquid is evaporated To generate an adsorption medium to be adsorbed by the adsorbent, and to condense the adsorption medium desorbed by the adsorbent, and to supply the liquid to the evaporation condenser and recover the liquid from the evaporation condenser Item 4. The liquid transport device according to any one of items 1 to 3.

  According to the above configuration, when the adsorption type heat pump includes the liquid transport device according to any one of claims 1 to 3, the entry of gas into the liquid transported to the evaporation condenser is suppressed. This improves the thermal efficiency of the adsorption device.

  By improving the thermal efficiency of the adsorption device, for example, the amount of latent heat of vaporization generated in the evaporation condenser can be increased in the adsorption step in which the adsorption device adsorbs the adsorption medium.

  A heat storage system according to claim 5 of the present invention is a heat storage apparatus having a heat storage material for adsorbing an adsorption medium which is steam and desorbing the adsorption medium, and a decompression vessel whose inside is decompressed, and the liquid is evaporated The evaporation condenser which generates the adsorption medium which the heat storage material adsorbs, condenses the adsorption medium which the heat storage material desorbed, liquid is supplied to the evaporation condenser, and the liquid is recovered from the evaporation condenser. And the liquid transport device according to any one of the items 1 to 3.

  According to the above configuration, when the heat storage system includes the liquid transport device according to any one of claims 1 to 3, the entry of gas into the liquid transported to the evaporation condenser is suppressed. Thereby, the thermal efficiency of the heat storage device is improved.

  By improving the thermal efficiency of the heat storage device, for example, the amount of heat stored by the heat storage device can be increased.

(Action)
Next, the operation of the liquid transfer device 10 will be described by a method of supplying water to the evaporation condenser 80 using the liquid transfer device 10 and a method of recovering water from the evaporation condenser 80 using the liquid transfer device 10 .

[Supply of water]
First, a method of supplying water (an example of liquid) to the evaporation condenser 80 using the liquid transport device 10 will be described. The water is supplied to the evaporative condenser 80 when the evaporative condenser 80 generates water vapor.

  Before the water is supplied to the evaporation condenser 80, as shown in FIG. 1, the on-off valve 16 is closed, and water is stored inside the container 12.

  The temperature and pressure inside the evaporation condenser 80 are, for example, 5 [° C.] and 0.9 [kPa]. Thus, the inside of the container 82 of the evaporative condenser 80 is an environment in which water vapor and water are in equilibrium.

  On the other hand, as described above, the pressure of the depressurized layer 18 of the container 12 is, for example, 0.1 [kPa].

  In this state, as shown in FIG. 2, the on-off valve 16 is opened from the closed state.

  Then, the drive member 34 moves the partition portion 20 downward via the support rod 28. As a result, the water stored inside the container 12 is pressed by the dividing section 20 and supplied to the inside of the container 82 of the evaporative condenser 80 through the communication pipe 14.

  Then, the heat exchange between the fluid flowing through the flow path pipe 84 and the water supplied to the inside of the container 82 generates steam.

  When the supply of water to the evaporation condenser 80 is ended, the open / close valve 16 is closed from the open state, and the drive member 34 stops the movement of the partition portion 20. Thus, the supply of water to the evaporation condenser 80 is completed.

[Collection of water]
Next, a method of recovering water (an example of the liquid) from the evaporation condenser 80 using the liquid transport device 10 will be described. The water is recovered from the evaporative condenser 80 when the evaporative condenser 80 condenses water vapor.

  Before the water is recovered from the evaporation condenser 80, as shown in FIG. 3, the on-off valve 16 is closed, and no water is stored inside the container 12. This is because all the water stored in the container 12 was supplied to the evaporative condenser 80 when the water was supplied to the evaporative condenser 80 using the liquid transport device 10.

  The temperature and pressure inside the evaporation condenser 80 are 90 [° C.] and 69.0 [kPa], for example, as the adsorber 90 deaerates the water vapor. Thus, the inside of the container 82 of the evaporative condenser 80 is an environment in which water vapor and water are in equilibrium.

  Then, when the steam desorbed by the adsorbent 94 flows into the inside of the container 82 of the evaporation condenser 80 through the pipe 88, the steam exchanges heat with the fluid flowing through the flow pipe 84, as shown in FIG. Condensed by

  Furthermore, the on-off valve 16 is opened from the closed state. Then, the drive member 34 moves the partition portion 20 upward through the support rod 28.

  As a result, the pressure in the communication pipe 14 is reduced, and the water condensed in the container 82 flows into the container 12 through the communication pipe 14 and is stored in the container 12. Thus, the water condensed by the evaporative condenser 80 is recovered.

  When the recovery of water from the evaporative condenser 80 is to be ended, the on-off valve 16 is closed from the open state, and the drive member 34 stops the movement of the partition section 20. Thus, the recovery of water from the evaporative condenser 80 is completed.

〔heat pump〕
Next, the operation of the heat pump 100 will be described.

  Here, the operation of the heat pump will be described by taking the case where two heat pumps 100 are provided as an example.

  As shown in FIG. 2, in one adsorption device 90, the adsorbent 94 adsorbs the water vapor supplied to the inside of the container 92 of the adsorption device 90 by heat exchange with the first heat medium. Then, the adsorbent 94 adsorbs the water vapor, whereby the adsorbent 94 generates heat (radiates heat) while adsorbing the water vapor (adsorption step).

  On the other hand, as shown in FIG. 4, in the other adsorption device 90, the adsorbent 94 desorbs the adsorbed water vapor by heat exchange with the second heat medium. Then, the adsorbent 94 desorbs the water vapor, whereby the adsorbent 94 absorbs heat while desorbing the water vapor (desorption step).

  Next, the adsorbent 94 which has adsorbed the water vapor desorbs the water vapor, and the adsorbent 94 which has desorbed the water vapor adsorbs the water vapor. Thus, one adsorbent 94 repeats adsorption and desorption, and the other adsorbent 94 repeats desorption and adsorption.

  Thereby, in the adsorption step, the fluid flowing through the flow passage pipe 84 of the evaporation condenser 80 is cooled.

(Summary)
As described above, the depressurized layer 18 of the container 12 is depressurized with respect to the atmospheric pressure. Thereby, it is possible to suppress gas from entering the water stored in the container 12 from between the seal member 24 and the inner peripheral surface of the container 12 as compared with the case where the pressure reducing layer 18 is at atmospheric pressure. . In other words, when water is transported to and from the evaporative condenser 80, entry of gas into the transported water can be suppressed.

  In addition, it is possible to improve the transport efficiency of water between the evaporative condenser 80 and the liquid transport device 10 by suppressing the gas from entering the water transported between the evaporative condenser 80.

  Further, in the heat pump 100, the transport efficiency of water between the evaporation condenser 80 and the liquid transport device 10 is improved, whereby the thermal efficiency of the adsorption device 90 can be improved.

  Further, by improving the thermal efficiency of the adsorption device 90, it is possible to effectively cool the fluid flowing through the flow path pipe 84 of the evaporative condenser 80, for example, in the adsorption step in which the adsorbent 94 adsorbs water vapor.

Second Embodiment
Next, an example of a liquid transport apparatus and a heat pump according to a second embodiment of the present invention will be described using FIGS. 5 to 8. The same members as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted, and parts different from the first embodiment will be mainly described.

(Constitution)
The liquid transport device 110 provided in the heat pump 200 according to the second embodiment includes a container 112 whose upper side is opened as shown in FIG. Specifically, the container 112 includes a bottom plate 112A and a side plate 112B.

  Furthermore, the liquid transport device 110 divides the inside of the container 112 into a pressure reduction layer 118 and an external layer 134 (an example of a gas layer) communicating with the outside of the container 12 and moves the partition unit 20 in the moving direction In the embodiment, the dividing unit 138 is movable in the same direction as the vertical direction.

  The dividing portion 138 is fixed to the dividing plate 140 which is sandwiched between the outer layer 134 and the depressurizing layer 118 while the plate surface is directed in the vertical direction, the end of the dividing plate 140, and the dividing plate 140 and the inner circumferential surface of the container 112 And a seal member 142 for sealing between them. Further, in the dividing plate 140, a pressure adjustment hole 144 used when the pressure reducing layer 118 is depressurized is formed.

  Further, the support rods 28 are integrally formed with the dividing plate 140 so as to penetrate the front and back of the dividing plate 140. Thus, the support rod 28 is an example of a connecting portion that connects the dividing portion 138 and the dividing portion 20. Thereby, the division part 138 and the partition part 20 move similarly.

(Action)
Next, the operation of the liquid transfer device 110 will be described by a method of supplying water to the evaporation condenser 80 using the liquid transfer device 110 and a method of recovering water from the evaporation condenser 80 using the liquid transfer device 10 .

[Supply of water]
A method of supplying water (an example of liquid) to the evaporation condenser 80 using the liquid transport device 110 will be described.

  The method of supplying water to the evaporation condenser 80 is the same as in the first embodiment, and as shown in FIGS. 5 and 6, the on-off valve 16 is opened from the closed state, and the drive member 34 is a support rod. The water is supplied to the inside of the container 82 of the evaporative condenser 80 by moving the partition unit 20 downward through the space 28.

  Here, since the volume of the pressure reducing layer 118 does not change due to the movement of the partition portion 20, the pressure of the pressure reducing layer 118 is maintained at a predetermined value (for example, 0.1 [kPa]).

  Further, the temperature and pressure inside the evaporation condenser 80 are, for example, 90 [° C.] and 69.0 [kPa]. Therefore, the partition portion 20 attached to the tip end portion of the support rod 28 is in contact with the space decompressed from the lower side, and the dividing portion 138 integrally formed with the support rod 28 is the upper side. Contact the outer layer 134 which is at atmospheric pressure. Due to this pressure difference, a force that causes the partition unit 20 to move downward acts on the partition unit 20.

  Thus, in the liquid transport device 110, the drive member 34 can reduce the force of moving the partition 20 downward, or move the partition 20 by a pressure difference.

[Collection of water]
Next, a method of recovering water (an example of a liquid) from the evaporation condenser 80 using the liquid transport device 110 will be described.

  The method of recovering water from the evaporation condenser 80 is the same as in the first embodiment, and as shown in FIGS. 7 and 8, the on-off valve 16 is opened from the closed state, and the drive member 34 is a partition By moving 20 upward, water is recovered inside the container 82 of the evaporative condenser 80.

Third Embodiment
Next, an example of a liquid transport apparatus and a heat pump according to a third embodiment of the present invention will be described using FIGS. 9 to 12. The same members as those of the second embodiment are denoted by the same reference numerals, and description thereof is omitted. Parts different from the second embodiment will be mainly described.

(Constitution)
The liquid transport apparatus 210 provided in the heat pump 300 according to the third embodiment, as shown in FIG. 9, includes a container 212 whose upper side is closed. Specifically, the container 212 includes a bottom plate 212A, a side plate 212B, and a ceiling plate 212C.

  Further, the dividing portion 138 separates the inside of the container 12 into a pressure reducing layer 118 and an air layer 234 which is a layer between the ceiling plate 212C. The air layer 234 is an example of a gas layer, and the ceiling plate 212C is an example of a separation unit that separates the air layer 234 from the outside of the container 212.

  The support rod 28 passes through a through hole 230 formed in a ceiling plate 212C of the container 212, and the tip of the support rod 28 is exposed to the outside of the container 212. A seal member 232 is provided which seals the outer periphery of the support rod 28 and the edge of the through hole 230.

  Furthermore, in the side plate 212B of the container 212, a pressure adjustment hole 226 for communicating the pressure reducing layer 118 with the outside is formed.

  Furthermore, in the side plate 212B of the container 212, a pressure adjustment hole 246 that communicates the air layer 234 with the outside is formed. Then, the liquid transport device 210 extracts air from the air layer 234 through the pressure adjustment hole 246, and sends air to the air layer 234 through the pressure adjustment hole 246, thereby increasing or decreasing the pressure of the air layer 234. As an air pump 250 is provided.

(Action)

[Supply of water]
First, a method of supplying water (an example of liquid) to the evaporation condenser 80 using the liquid transport device 210 will be described.

  Before the water is supplied to the evaporation condenser 80, as shown in FIG. 9, the on-off valve 16 is closed, and water is stored in the container 212. In addition, the pressure of the air layer 234 is the same as the pressure inside the container 82 of the evaporation condenser 80.

  In this state, as shown in FIG. 10, the on-off valve 16 is opened from the closed state. Then, the air pump 250 pumps air into the air layer 234 through the pressure control hole 246. Thereby, the pressure of the air layer 234 is increased.

  As the pressure of the air layer 234 increases, the dividing portion 138, the support rod 28, and the dividing portion 20 move downward. As a result, the water stored inside the container 212 is pressed by the partition unit 20 and supplied to the inside of the container 82 of the evaporation condenser 80 through the communication pipe 14.

In addition, the pressure of the air layer 234 is the same as the pressure inside the container 82 of the evaporation condenser 80.

  In this state, as shown in FIG. 12, the on-off valve 16 is opened from the closed state. And then, the air pump 250 draws air from the air layer 234 through the pressure control hole 246. This reduces the pressure in the air layer 234.

  As the pressure of the air layer 234 decreases, the dividing portion 138, the support rod 28, and the dividing portion 20 move upward. As a result, the inside of the communication pipe 14 is depressurized, and the water condensed inside the container 82 flows into the inside of the container 212 through the communication pipe 14 and is recovered inside the container 12.

  When the recovery of water from the evaporation condenser 80 is ended, the open / close valve 16 is closed from the open state, and the air pump 250 stops the extraction of the air from the air layer 234 to Stop moving.
