Description

  The present invention relates to an air conditioning apparatus and an air conditioning system. More specifically, the present invention relates to a device in which the vicinity of the installation location of the air conditioner is not contaminated with water condensed on the heat generating portion.

  2. Description of the Related Art Conventionally, an air conditioner using radiant heat of a heat exchanger has been used in order to eliminate a draft feeling that is generated by a blow-type air conditioner and is uncomfortable for a person around. As such an air conditioner, for example, an air conditioner described in Patent Document 1 has been proposed in which a plurality of heat exchangers are horizontally arranged and arranged in the vertical direction.

  An air conditioner 9 described in Patent Document 1 shown in FIG. 12 circulates a heat medium inside a flow path member and heats or cools the outside of the flow path member by heat exchange with the heat medium. The heat exchanger 90, in which the core member is accommodated inside the flow path member and the flow path for circulating the heat medium is formed by the surface of the core member and the inner surface of the flow path member, is arranged in the vertical direction. Alternatively, they are arranged side by side in the horizontal direction or in other directions, and the heat medium is circulated through the heat exchanger 90.

  By providing the above-described configuration, the air conditioner 9 can eliminate a draft feeling that is uncomfortable for a person in the vicinity during operation, and the temperature rise on the surface of the flow path member, which is a heat exchange unit, can be accelerated. High convenience.

International Publication No. WO2009 / 130764

  On the other hand, in the air conditioner 9 described in Patent Document 1, since the heat exchanger 90 is in the shape of a rod and is arranged in the vertical direction, the dew condensation water generated in the heat exchanger 90 during cooling operation is reduced. In some cases, the air conditioner 9 may drip on the front side or the back side of the air conditioner 9 to contaminate the vicinity where the air conditioner 9 is installed.

  In addition, as shown in FIG. 13, when the reflector 91 is arranged on the back side of the air conditioner 9 in order to improve the heat radiation efficiency, indoor convection occurs and the air exchanges heat with the reflector 91. May enter the gap between the heat exchangers 90 and flow in a direction opposite to the reflector 96 from between the heat exchangers 90. At this time, splashes of condensed water generated in the heat exchanger 90 ride on the convection air and scatter to the front side of the air conditioner 9 and may contaminate the surroundings. Such dirt caused by condensed water is unfavorable for hygiene because it looks bad and causes mold and the like.

  The present invention was devised in view of the above points, and an air conditioner and an air in which the surroundings of the installation location are prevented from being contaminated by dripping or scattering of water condensed on the heat generating portion. The purpose is to provide a harmony system.

  In order to achieve the above object, an air conditioner according to the present invention includes a support frame that has a support portion that is erected with respect to an installation surface and that is spaced apart in the horizontal direction, and the support portion of the support frame. In the region between the two, each is horizontally suspended with a space in the vertical direction, the flowable heat medium can flow through the inside, and each flow tube is covered, and the outer shape of the cross section is flat or elliptical And a heat generating part having a structure capable of dissipating heat conducted from the flow pipe to the outside, and an outer shell body attached so that a major axis direction orthogonal to the longitudinal direction is inclined in the same direction; And a reflection surface that reflects radiant heat from the heat generating portion and is impermeable to water, and the lower edge in the major axis direction of the outer shell and the reflection surface are spaced apart from each other. A reflector disposed so as to be below and below the heat generating part Is placed under the reflector, the upper part is provided with a trough-shaped receiving portion is open.

  Here, the support frame horizontally supports the heat generating portion in a region between the support portions, and supports the outer shell body of the heat generating portion with an interval in the vertical direction.

  When a fluid heat medium flows through a flow pipe that fits inside the heat generating part, the heat is transferred to the outer shell body that can dissipate the heat conducted from the flow pipe to the outside, and radiant heat is radiated around the heat generating part. To do. In addition, the outer shell that covers the flow pipe prevents the flow pipe from being deformed or damaged by pressure or impact from the outside, and has a larger surface area than when the heat generating portion is a simple pipe body. The heat exchange efficiency is improved.

  The heat generating part is arranged in the horizontal direction and the outer shell constituting the heat generating part has a cross section (the term “cross section” is used to mean a cross section in a direction perpendicular to the longitudinal direction of the heat generating part. The same is applied to the outer shape of the heat generating part, so that the condensed water produced on the surface of the heat generating part is inclined. It flows down only to the reflector side which is the direction.

The reflector reflects the radiant heat radiated to the reflector side of the heat generating part, and releases the radiant heat to the outside of the air conditioner through the gap between the heat generating parts. In addition, if the dew condensation water generated from the heat generating part adheres to the reflection plate, the dew condensation water that has adhered flows down to the receiving part located below along the plate surface.
The gap between the lower edge portion and the reflecting surface in the major axis direction of the outer shell of the heat generating portion serves as a flow path when the air heated or cooled by the heat generating portion rises or falls.

  The receiving part receives the condensed water dripping through the heat generating part or the condensed water dripping through the reflecting plate. In addition, the receiving portion prevents condensation from convection in the downward direction from the top during cooling, so as to prevent condensation, and induces the chill to flow out of the apparatus by changing the direction of convection.

  The heat generating part, the reflecting plate and the receiving part are combined to receive the condensed water generated in the heat generating part so as not to leak.

  An air conditioner including a support frame, a heat generating unit, a reflecting plate, and a receiving unit does not feel an uncomfortable draft feeling during operation, and air heated or cooled by the heat generating unit is not reflected in the reflecting plate. In addition to directly heating or cooling the space in front of the convection, convection occurs in the installation space, so that the installation space can be efficiently heated or cooled.

  The outer shell body has a pair of shell members having the same shape, and each shell member has a contact portion formed with a concave surface that fits in close contact with the outer surface of the flow pipe, and the other shell. There is provided a fitting portion in which a protruding piece portion that is fitted and fitted in a concave portion formed in the member and a concave portion in which the protruding piece portion formed in the other shell member is fitted and fitted is formed. In the case of a structure in which the same shell member is fitted, it is a simple structure in which the provided protruding piece part and the recessed part are simply fitted together in the fitting part. Since no special technique is required, quick assembly is possible.

  Moreover, since the shell member is the same part, waste of parts procurement can be eliminated, and the manufacturing cost can be reduced. In addition, the concave surface portion formed in the fitting portion of the shell member holds the outer shell body and the flow pipe so that they do not move in a state of being fitted with the flow pipe interposed therebetween, and the flow Receives heat from the tube and transfers it to the surface side of the outer shell. Furthermore, the outer shell body does not adhere to the support frame, and by adjusting the adhesion with the flow pipe, the outer shell body can be rotated around the flow pipe to set the angle in the short direction to the required angle. The radiation efficiency can also be adjusted.

  When the fluid heat medium is hot water or cold water, it is easier to handle than when the fluid heat medium is oil or a chemical substance, and the environmental load can be suppressed during disposal.

  When the fluid heat medium is a refrigerant, the performance of the air conditioner such as temperature rise and maintainability can be improved by adopting a heat exchange efficiency, rust prevention property, etc. that is better than water. Can do. In this case, the refrigerant to be used may be dedicated to the air conditioner, or may be common to a refrigerant circuit of an air conditioner described later.

  In the case where the support frame includes a panel body that is attached to a region on the opposite side of the reflection plate with the heat generating portion interposed therebetween, and that has a clearance for ventilation between the ceiling direction or the installation surface. In addition, the panel body serves not only as a protective cover for protecting a heat generating part or a mechanism part such as a branch part of the flow pipe but also as a blindfold. Further, the panel body sandwiches the heat generating part together with the reflecting plate to produce a chimney effect, and warm air or cold air is released from the gap for ventilation to promote air convection, improving heating efficiency or cooling efficiency. .

  In the panel body, at least a portion covering the heat generating part has a structure through which the radiant heat generated by the heat generating part can pass, and the panel body serves as a protective cover for the heat generating part and passes through the panel body. The radiant heat can directly warm or cool the user and the surrounding air.

  When advertisements, signs, pictures, or photographs are displayed on the surface of the panel body, the panel body can be used as an advertisement panel or a sign board. In other words, the air conditioner is a form that is greatly exposed to the indoor space in which it is installed and has a large presence. Therefore, when displaying an advertisement, it can have a more effective function as an advertisement, and an art image. Etc., the interior can be produced in various ways, such as creating a gorgeous space with art images or a space where people around can relax.

  On the surface of the outer shell, one or more selected from knurling, anodizing, coating for heat radiation, coating for emitting far infrared rays, deodorizing function, antibacterial function, or adsorption / decomposition function of volatile organic compounds When processing or coating is performed, the heat generating portion can have various functions by performing these processing and the like.

  More specifically, by applying knurling, alumite processing or heat dissipation coating, the heat dissipation of the heat generating part is improved, heat exchange in the heat generating part is performed more efficiently, and if a far infrared emission coating is applied, The far-infrared rays emitted from the heat generating part are combined with the radiant heat to efficiently adjust the indoor temperature. Furthermore, by applying a coating having a deodorizing function, an antibacterial function, or a function of adsorbing and decomposing volatile organic compounds, the maintenance of the air conditioner can be simplified by these functionalities and can be used comfortably.

  In order to achieve the above object, an air conditioning system of the present invention includes a support frame that has a support portion that is erected with respect to an installation surface and that is spaced apart in the horizontal direction, and the support portion of the support frame. In the area between the two, each is installed horizontally with a space in the vertical direction, and the flowable heat medium can flow through the inside, covering each flow pipe, and the outer shape of the cross section is flat or oval A heat generating part including an outer shell body having a structure capable of radiating heat conducted from the flow pipe to the outside and attached so that a major axis direction perpendicular to the longitudinal direction is inclined in the same direction; A reflection surface that reflects radiant heat from the heat generation portion and is impermeable is formed, and the lower edge portion and the reflection surface are relatively spaced apart in the major axis direction of the outer shell. The reflector arranged so as to be below the heat generating part and the opposite An air conditioner having a bowl-shaped receiving portion disposed below the plate and having an upper portion opened, and operated in combination with the air conditioner, a compressor, an expansion valve, a flow path switching valve, and an indoor heat exchange And a refrigerant circuit that performs a refrigeration cycle by circulating a refrigerant and connecting the condenser and the outdoor heat exchanger, the air conditioner is incorporated in the refrigerant circuit, and the refrigerant and heat are heated in the indoor heat exchanger. An air conditioner for supplying the exchanged air into the room by a fan.

  Here, the support frame horizontally supports the heat generating portion in a region between the support portions, and supports the outer shell body of the heat generating portion with an interval in the vertical direction.

  When a fluid heat medium flows through a flow pipe that fits inside the heat generating part, the heat is transferred to the outer shell body that can dissipate the heat conducted from the flow pipe to the outside, and radiant heat is radiated around the heat generating part. To do. In addition, the outer shell that covers the flow pipe prevents the flow pipe from being deformed or damaged by pressure or impact from the outside, and has a larger surface area than when the heat generating portion is a simple pipe body. The heat exchange efficiency is improved.

  The heat generating part is arranged in the horizontal direction and the outer shell constituting the heat generating part has a cross section (the term “cross section” is used to mean a cross section in a direction perpendicular to the longitudinal direction of the heat generating part. The same is applied to the outer shape of the heat generating part, so that the condensed water produced on the surface of the heat generating part is inclined. It flows down only to the reflector side which is the direction.

The reflector reflects the radiant heat radiated to the reflector side of the heat generating part, and releases the radiant heat to the outside of the air conditioner through the gap between the heat generating parts. In addition, if the dew condensation water generated from the heat generating part adheres to the reflection plate, the dew condensation water that has adhered flows down to the receiving part located below along the plate surface.
The gap between the lower edge portion and the reflecting surface in the major axis direction of the outer shell of the heat generating portion serves as a flow path when the air heated or cooled by the heat generating portion rises or falls.

  The receiving part receives the condensed water dripping through the heat generating part or the condensed water dripping through the reflecting plate. In addition, the receiving portion prevents condensation from convection in the downward direction from the top during cooling, so as to prevent condensation, and induces the chill to flow out of the apparatus by changing the direction of convection.

  The heat generating part, the reflecting plate and the receiving part are combined to receive the condensed water generated in the heat generating part so as not to leak.

  An air conditioner including a support frame, a heat generating unit, a reflecting plate, and a receiving unit does not feel an uncomfortable draft feeling during operation, and air heated or cooled by the heat generating unit is not reflected in the reflecting plate. In addition to directly heating or cooling the space in front of the convection, convection occurs in the installation space, so that the installation space can be efficiently heated or cooled.

  In addition, the air conditioner includes a refrigerant circuit that performs a refrigeration cycle by connecting a compressor, an expansion valve, a flow path switching valve, an indoor heat exchanger, and an outdoor heat exchanger, and circulating the refrigerant to perform an indoor heat exchanger. By supplying the air heat-exchanged with the refrigerant in the room by a fan, air-conditioning in the installation space can be performed by forced convection by air blowing.

  In addition, since the air conditioner is incorporated in the refrigerant circuit of the air conditioner, the refrigerant is supplied from the air conditioner side, so no equipment such as a compressor is required in the air conditioner, and control linked to the air conditioner is performed. It is also possible to do this.

  For example, the air conditioner has the advantage that the space can be quickly brought to the target temperature by forced convection by the air blown from the fan, but on the other hand, the air blown from the fan has the disadvantage that the human body feels uncomfortable (draft feeling). The radiation-type air conditioner has an advantage that it does not give such a draft feeling to those around it, but it has a disadvantage that it takes time to reach the target temperature in the space as compared with an air conditioner.

  On the other hand, by operating in combination with an air conditioner and an air conditioner, for example, the air conditioner can be brought close to the target temperature in a short time by operating mainly with the air conditioner. Since the temperature in the space can be maintained, the fan operating time of the indoor heat exchanger can be kept short, and air conditioning that does not give an unpleasant draft to the human body can be achieved.

  In addition, when the air conditioner and the air conditioner are operated at the same time, the radiant heat from the air conditioner directly affects the sensation of nearby people, and the air conditioner performs overall air conditioning. It takes less time to get comfort for those around you than driving on the road. Furthermore, the temperature in the space can be equalized quickly by convection of the radiant heat from the air conditioner and the blast from the fan.

  As described above, the air conditioning system of the present invention synergizes the advantages of an air conditioner that is supplied by a fan and the advantages of a radiant air conditioner and complements the disadvantages, so that the temperature control of the air conditioning is efficient and effective. To be done.

According to the air conditioner of the present invention, it is possible to prevent the periphery of the installation location of the air conditioner from being contaminated with water condensed on the heat generating portion.
According to the air conditioning system of the present invention, it is possible to prevent the surroundings of the installation location of the air conditioning apparatus from being contaminated with water condensed on the heat generating portion.

  The embodiment of the present invention will be described in more detail with reference to FIGS. In addition, the code | symbol in each figure is attached | subjected within the range which reduces complexity and makes it easy to understand. In addition, the term “front side” described below is used in the same meaning as the above-mentioned “region on the opposite side of the reflector plate with the heat generating portion interposed therebetween”.

[First Embodiment]
The air conditioner 1A includes a support frame 21, a heat generating portion 22 attached to the support frame 21, a reflecting plate 23 that reflects radiant heat from the heat generating portion 22, a bowl-shaped receiving portion 24, and a panel body 3a. Each part will be described below.

  Reference is made to FIG. The support frame 21 has a support part 210 that is erected with respect to the installation surface F (floor surface or the like if indoors) of the air conditioner 1A and is arranged with a gap in the horizontal direction. Each support portion 210 is housed inside so that connection portions located at both ends of a later-described flow pipe 221 are not visible from the outside (see FIG. 1A). Further, a reinforcing material 211 is provided horizontally on the upper side of the region between the support portions 210.

  The heat generating part 22 is disposed in a region between the support parts 210 of the support frame 21, and a heat transfer pipe 221 through which the fluid heat medium can flow and the heat that covers the flow pipe 221 and is conducted from the flow pipe 221. It is comprised by the outer shell body 222 which is the structure which can thermally radiate to the exterior.

  The flow pipes 221 meander in the vertical direction so as to be connected along the same plane in the vertical direction so as to be connected at both ends, and the outer shell bodies 222 are respectively attached to the horizontal portions arranged at regular intervals. It is a structure. Each outer shell body 222 is attached so that the major axis direction of the transverse section is inclined downward toward the reflecting plate 23 (see FIG. 1B).

  More specifically, the outer shell body 222 has a pair of shell members 223a and 223b having the same shape, and each shell member 223a and 223b is formed with a concave surface that fits in close contact with the outer surface of the flow pipe 221. Contacted portions 226a, 226b, a projecting piece 225a (225b) fitted into and fitted into a recess 224b (224a) formed in the other shell member 223b (223a), and the other shell member 223b ( 223a) is provided with a fitting portion formed with a recessed portion 224a (224b) into which the protruding piece portion 225b (225a) is fitted and fitted, and the shell members 223a and 223b are fitted together to The surface has a slightly flat and substantially elliptical structure (see FIG. 2).

  In addition, the surface of the outer shell 222 is subjected to knurling and anodizing which are unevenness extending in the longitudinal direction, thereby improving the corrosion resistance and increasing the surface area to improve the efficiency during heat exchange. It is improving.

  In the present embodiment, the inclination angle when attaching the outer shell body 222 may be within a range of 1 ° to 89 °, where the angle at which the major axis of the elliptical cross section of the outer shell body 222 is horizontal is 0 °. Furthermore, it is preferably within a range of 35 ° to 70 °. This is because the radiant flux generated from the lower surface side of the outer shell body 222 tends to be directed from the front side of the air conditioner 1A to the front side floor as long as it is within the same inclination angle range, as will be described later. Further, the outer shell body 222 may be fixed to the support frame 21 with screws or the like so as to maintain a predetermined inclination angle, or the outer shell body 222 is attached so as to be axially rotatable so that a person around can incline. You may enable it to set an angle suitably.

  In the present embodiment, the outer shell body 222 is knurled and anodized on the surface, but is not limited thereto. For example, when one or more processes or coatings selected from other heat radiation coatings, far-infrared emission coatings, deodorant functions, antibacterial functions, or coatings with adsorption and decomposition functions of volatile organic compounds are applied By performing these processes and the like, the heat generating portion can have various functions.

  In the present embodiment, the flow pipe 221 is a meander pipe as described above, but is not limited to this. For example, the flow pipe is spanned between a pair of vertical portions extending in the vertical direction and each vertical portion. Alternatively, a ladder-like configuration having a plurality of horizontal portions may be used. In addition, the flow pipe 221 has a connection part 227a connected to the fluid heat medium injection pipe at the upper end and a connection part 227b connected to the return pipe of the fluid heat medium at the lower end. For example, the connection part to the injection pipe / return pipe may be provided in the side part direction of the air conditioner 1A, or three or more may be provided. Moreover, you may provide both the connection parts to an injection pipe / return pipe toward the upper end or lower end of 1 A of air conditioning apparatuses.

  The reflection plate 23 is formed of a heat insulating material and has a reflection surface 231 that is impermeable to water. The reflection surface 231 is spaced from the lower edge portion in the major axis direction of the outer shell 222. They are arranged so as to face each other. A guide plate 232 bent at an obtuse angle toward the heat generating portion 22 is attached to the lower end of the reflecting plate 23. The tip of the guide plate 232 is positioned inside a receiving portion 24 described later (see FIG. 1B).

  The receiving part 24 is below the lowermost one of the outer shells 222 of the heat generating part 22 and below the reflecting plate 23 (more specifically, below the guide plate 232 attached to the reflecting plate 23). It has a structure in which the upper part is opened so that it can be received through the guide plate 232 or dropped from the heat generating part 22.

  Panel body 3a is formed of punching metal, and is attached to the lower front side of air conditioner 1A. The panel body 3a covers the receiving portion 24, the piping portion (not shown) and the like so as to be blind when viewed from the front direction. Moreover, the panel body 3a is attached so that a clearance for ventilation may be formed between the panel body 3a and the installation surface F.

  In the present embodiment, the panel body is attached to the lower front side of the air conditioner. However, the present invention is not limited to this, and when a pipe part (not shown) or the like is provided in the upper part, The aspect attached to the front side upper direction of a harmony device may be sufficient.

  Examples of the fluid heat medium that circulates through the circulation pipe 221 include liquid (phase) heat (hot) water, steam, cold water, liquid-phase refrigerants such as hydro-chlorofluoro-carbon, hydro-fluoro-carbon, gas-liquid two-phase refrigerant, gas Although a phase refrigerant is mentioned, it is not limited to this, You may employ | adopt other well-known fluid heat | fever media.

As a modification of the heat generating part, the surface of the outer shell body facing the reflector side is subjected to water-repellent treatment or a process that easily causes condensed water to flow down, such as a guide groove, on the opposite side of the reflector plate. The region may be a mode in which processing for enhancing the heat radiation effect such as knurling is performed. In this case, the dew condensation water generated in the heat generating portion or the dew condensation water dropped from the outer shell body located on the heat generating part easily flows down to the reflecting plate side and is difficult to face the front side of the air conditioner 1A. In addition, the countermeasure against the dew condensation water by performing hydrophilic processes, such as a blast process, on the surface of the area | region which faced the reflector side is not excluded.
On the other hand, since the surface facing the front of the air conditioner 1A on the surface of the outer shell is subjected to knurling or the like, the heat dissipation efficiency to a person or space located on the front side is good.

  The operation of the air conditioner 1A of the present invention will be described with reference to FIGS. 1 to 6, particularly FIGS. 4 to 6. FIG.

  When the fluid heat medium is circulated through the flow pipe 221, the heat of the heat generating part 22 is transmitted to the outer shell 222 and is radiated to the outside. The outer shell 222 prevents the flow pipe 221 from being deformed or damaged by pressure or impact from the outside, and has a larger surface area than that in the case where the heat generation part is simply the flow pipe 221, thereby improving heat exchange efficiency. I am letting. The reflecting plate 23 reflects the radiant heat radiated to the reflecting plate 23 side of the heat generating part 22 and releases the radiant heat to the front direction side of the air conditioner 1 </ b> A through the gap formed in the heat generating part 22.

  Further, as described above, the outer shell 222 of the heat generating part 22 is attached at an inclination, so that the condensed water T generated on the surface of the outer shell 222 of the heat generating part 22 flows only to the reflector 23 side. To do. Condensed water T generated from the heat generating part 22 and adhered to the reflecting plate 23 flows down to the receiving part 24 positioned below along the plate surface (see FIG. 5).

  In addition, as described above, since the heat generating portion 22 is attached at an inclination, the radiant heat generated from the lower surface side of the outer shell 222 of the heat generating portion 22 is changed from the front direction of the air conditioner 1A to the floor direction. Since it is radiated | directly toward, the person who is in the front side of 1 A of air conditioning apparatuses can directly feel either radiant heat of cooling or heating.

  As shown in FIG. 4 or FIG. 6, during the cooling / heating operation, a main flow of air that rises or falls along the reflecting plate 23 is generated, and the air passing through the gaps of the outer shells 222 of the respective heat generating units 22 In the case of joining or splitting, the inclined outer shell body 222 guides air easily and increases the flow velocity of air passing through the gap. Further, during heating, the radiant heat generated by the portion on the lower surface side of the outer shell body 222 warms the floor surface in the direction of the radiant flux, thereby enhancing the upward convection effect of the indoor air generated thereby.

  The outer shell body 222 has the above-described structure, and is a simple structure in which the provided protruding piece portions 225a and 225b and the recessed portions 224a and 224b are fitted together by the fitting portion. At this time, since special tools and special techniques are not required, quick assembly is possible.

  Moreover, since the shell members 223a and 223b are the same parts, it is possible to reduce the cost of manufacturing by reducing the waste of parts procurement. In addition, the outer shell body 222 and the flow pipe 221 move in close contact with each other with the flow pipes 221 fitted by the contact parts 226a and 226b formed in the fitting parts of the shell members 223a and 223b. It is held so that there is no.

  In the present embodiment, the outer shell body 222 is fixed to the support frame 21 using a fixing means such as a screw and is held at a predetermined mounting angle. However, the present invention is not limited to this. By adjusting the close contact with the flow pipe 221 without adhering to the frame 21, the angle in the short direction can be set to the required angle by rotating around the flow pipe 221, thereby adjusting the radiation efficiency. You may be able to do that.

  During the cooling operation shown in FIGS. 4 and 5, the air in the installation space convects from above to below as indicated by arrows. Further, the gap formed in the heat generating part 22 also becomes an air flow path by the induction by the inclined surface of the outer shell 222 of the heat generating part 22, and the air passing through the gap formed in the heat generating part 22 is reflected from the heat generating part 22. The air gap between the plates 23 merges with the air descending along the reflecting plate 23. At this time, even if the condensed water T generated in the heat generating part 22 is dropped on the outer shell body 222 located below, the outer shell body 222 is inclined toward the reflector 23 as described above. It does not scatter to the front side of 1A.

  When the condensed water T that has been dropped contacts the lower outer shell body 222 and scatters and adheres to the reflection plate 23 (see the enlarged view of FIG. 5), the condensed water T that adheres travels down the plate surface. It flows down to the receiving part 24 located. As described above, the heat generating part 22, the reflecting plate 23 including the guide plate 232, and the receiving part 24 receive the condensed water T generated in the heat generating part 22 so as not to leak.

  In addition, the receiving part 24 prevents the cold air that convects from the top to the bottom when cooling down from condensing on the installation surface F so that it does not directly hit the installation surface, and changes the direction of convection to the outside of the apparatus. Guide the cold air to flow.

  During the heating operation shown in FIG. 6, the air in the installation space convects from below to above as indicated by arrows. In addition, since the dew condensation water T does not arise in the heat generating part 22 at the time of heating operation, even if air flows from the clearance gap formed in the heat generating part 22 to the front side of the air conditioner 1A, the contamination by the dew condensation water T does not occur. .

  Thus, according to the air conditioner 1 </ b> A, the periphery of the place where the air conditioner 1 </ b> A is installed can be prevented from being contaminated with the dew condensation water T generated in the heat generating part 22. In addition, the air conditioner 1A is not blasted by forced convection as in the conventional air conditioner (air conditioner) during operation, but the air flow generated in the space in the installation area is a natural convection due to the temperature difference in the space. Therefore, the person who is in the surroundings does not feel an uncomfortable draft, and the air heated or cooled by the heat generating part 22 directly heats or cools the space in front of the reflector 23 and also in the installation space. Since convection occurs, the installation space can be efficiently heated or cooled.

[Second Embodiment]
The air conditioner 1B shown in FIG. 7 is a mode in which panel bodies 3b and 3c that cover the heat generating part 22 are further provided on the front side of the air conditioner 1A. Since structural parts other than the panel bodies 3b and 3c are the same as those of the air conditioner 1A, common structural parts are denoted by the same reference numerals as those of the air conditioner 1A, and description thereof is omitted.

  The panel bodies 3b and 3c are formed of punching metal, and are attached so as not to be seen from the upper part of the front side of the air conditioner 1B over the intermediate part so as to cover the heat generating part 22. Moreover, the panel body 3c is attached so that the clearance for ventilation | gas_flowing may be formed between ceiling surfaces.

  Since the panel bodies 3b and 3c serve as a protective cover for the heat generating part 22 and have a structure through which the radiant heat generated by the heat generating part 22 can pass, the radiant heat that passes through the surrounding person and the surrounding air directly. Can be warmed or cooled.

  Further, as shown in FIG. 7, advertisements are displayed on the surfaces of the panel bodies 3b and 3c, and the panel body portion can be used as an advertisement panel or a sign board. In other words, the air conditioner 1B has a large presence and a large presence in the indoor space where it is installed. Therefore, when displaying an advertisement, the air conditioner 1B can have a more effective function as an advertisement. When displaying an image or the like, it is possible to produce various interiors such as creating a gorgeous space or a space where people in the surroundings can relax by using art images.

  In addition, the panel bodies 3b and 3c sandwich the heat generating part 22 together with the reflecting plate 23 to generate a chimney effect. Warm air or cold air is released from a gap for ventilation, and air convection is promoted. Efficiency or cooling efficiency is improved. Further, the panel bodies 3b and 3c have a large number of holes through which the radiant heat passing through the inner and outer surfaces can pass, so that the gaps formed in the heat generating part 22 along the outer shell body 222 of the heat generating part 22 are fast. When air flows at a speed, the pressure in the gap decreases (from Bernoulli's theorem), air is taken into the gap from the holes formed in the panel bodies 3b and 3c, and the area inside the panel bodies 3b and 3c. The flow rate of air through the air flow increases, and the convection of room air is further promoted.

  Furthermore, the panel members 3b and 3c are attached so that the heat generating part 22 is built in, and the heat generating part 22 cannot be directly touched by hand. Therefore, although the heat generating part 22 may become high temperature during heating with a gas phase refrigerant or the like, it is safe for those around because the person around it does not touch the heat generating part 22 by mistake.

In addition, since it is the same as that of 1 A of air conditioning apparatuses except the structure part of a flow pipe, the same code | symbol as the air conditioning apparatus 1A is attached | subjected to a common structural part, and description is abbreviate | omitted.

  The circulation pipe 221a is meandering in the up-down direction so as to be connected along the same plane in the vertical direction so as to be connected at both ends, and more specifically, unlike the circulation pipe 221, a plurality of pipes are formed from the first vertical portion. A structure that branches as horizontal portions (six in this embodiment), and each horizontal portion is connected to a second vertical portion that is spaced from the first vertical portion and merges into one again Such a structure is continuously provided in the vertical direction (see FIG. 8). In addition, although the flow of the fluid heat medium is indicated by an arrow, the present invention is not limited to this, and for example, when the flow of the fluid heat medium is reversed by operation switching as in a fifth embodiment described later. There is also.

  According to the air conditioner 1C using the flow pipe 221a, the resistance value of the fluid heat medium flowing through the flow pipe 221a is lower than that in the case of a simple meander pipe, thereby sending out the fluid heat medium. Therefore, the load applied to the compressor or pump can be reduced.

[Fourth Embodiment]
The air conditioner 1D shown in FIG. 9 is an aspect in which the height of the air conditioner 1A is lowered. In addition, since it is substantially the same as that of the air conditioner 1A, common structural parts are denoted by the same reference numerals as those of the air conditioner 1A, and description thereof is omitted.

[Fifth Embodiment]

  In the fifth embodiment of the present invention shown in FIGS. 10 and 11, an air conditioning system S is configured by one outdoor unit 40 and two indoor units connected in series to the outdoor unit 40. Yes. One of the two indoor units is a general convection type indoor unit 41, and the other is the air conditioner 1A. The convection type indoor unit 41 and the air conditioning apparatus 1A are installed in a room or the like having an air conditioning target area, and have a function of cooling or heating the air conditioning target area.

  The outdoor unit 40 and the convection type indoor unit 41, the refrigerant pipe 42, the compressor 43, the outdoor heat exchanger 44, the expansion valve 45, the indoor side heat exchanger 46, and the four-way switching valve 47, which will be described later, are a so-called air blower. Hereinafter, in the description of the operation, the device may be simply referred to as “air conditioner”. Moreover, about the air conditioning apparatus 1A used in this embodiment, since a structure and an effect | action are as having stated previously, description is abbreviate | omitted.

  The convection type indoor unit 41 and the air conditioner 1 </ b> A are connected to each other through a refrigerant pipe 42. Therefore, the convection type indoor unit 41 and the air conditioner 1A form a part of the refrigerant circuit, and can circulate the refrigerant in the refrigerant circuit to perform a cooling operation or a heating operation. 10 and 11, the air conditioning system S has one outdoor unit, one convection type indoor unit 41, and one air conditioning apparatus 1A, but is limited to the number shown. Not what you want.

  As shown in FIGS. 10 and 11, the outdoor unit 40 has a known structure including a compressor 43, an outdoor heat exchanger 44, and an expansion valve 45. The convection indoor unit 41 has a known structure including an indoor heat exchanger 46 and a blower fan (not shown) that sends air to the indoor heat exchanger 46.

  The indoor heat exchanger 46 functions as an evaporator during cooling operation, and functions as a condenser (heat radiator) during heating operation, and performs heat exchange between air supplied from a blower such as a fan (not shown) and the refrigerant. Then, heating air or cooling air to be supplied to the air conditioning target area is created. The above-described devices are connected by the refrigerant pipe 42 and constitute a part of the refrigeration cycle (refrigerant circuit) of the air conditioning system S.

With reference to FIG. 10 and FIG. 11, the flow of the refrigerant at the time of various operations of the air conditioning system S will be described.
(During cooling operation, FIG. 11 (a))
When the cooling operation is executed by the air conditioning system S, the four-way switching valve 47 is switched so that the refrigerant discharged from the compressor 43 flows into the outdoor heat exchanger 44, and the compressor 43 is driven.

  The refrigerant sucked into the compressor 43 is discharged in a high-pressure and high-temperature gas state by the compressor 43 and flows into the outdoor heat exchanger 44 through the four-way switching valve 47. The refrigerant that has flowed into the outdoor heat exchanger 44 is cooled while dissipating heat to air supplied from a blower (not shown), and flows out of the outdoor heat exchanger 44 as a low-pressure and high-temperature liquid refrigerant.

  The liquid refrigerant flowing out of the outdoor heat exchanger 44 passes through the expansion valve 45 and flows into the convection type indoor unit 41. The refrigerant flowing into the convection indoor unit 41 becomes a two-phase refrigerant. The low-pressure two-phase refrigerant flows into the indoor heat exchanger 46 and is evaporated and gasified by absorbing heat from air supplied from a blower (not shown). At this time, cooling air is supplied to an air conditioning target space such as a room, and cooling operation of the air conditioning target space is realized.

  The two-phase refrigerant that has flowed out of the indoor heat exchanger 46 flows out of the convection type indoor unit 41, flows into the air conditioner 1 </ b> A, and passes through the heat generating unit 22. At this time, the atmosphere of the air-conditioning target space such as the room, that is, the air is cooled together with the endothermic action with the atmosphere, and the air-conditioning target space is cooled.

The refrigerant flowing out of the air conditioner 1A flows into the outdoor unit 40, passes through the four-way switching valve 47 of the outdoor unit 40, and is sucked into the compressor 43 again.
The cooling cycle is performed by repeating the above refrigerant cycle.

(During heating operation, FIG. 11 (b))
When the heating operation is executed by the air conditioning system S, the four-way switching valve 47 is switched so that the refrigerant discharged from the compressor 43 flows into the indoor heat exchanger 46, and the compressor 43 is driven. The refrigerant sucked into the compressor 43 is discharged in a high-pressure and high-temperature gas state by the compressor 43, and flows into the air conditioner 1A through the four-way switching valve 47.

  The refrigerant that has flowed into the air conditioning apparatus 1A releases radiant heat at the heat generating unit 22 and warms the atmosphere of the air conditioning target space such as a room. The refrigerant that has flowed out of the air conditioner 1A flows into the indoor heat exchanger 46 of the convection indoor unit 41. The refrigerant flowing into the indoor heat exchanger 46 is cooled while dissipating heat to air supplied from a blower (not shown), and becomes a liquid refrigerant. At this time, heating air is supplied to an air conditioning target space such as a room, and a heating operation of the air conditioning target space is realized.

The liquid refrigerant that has flowed out of the indoor heat exchanger 46 is decompressed by the expansion valve 45 and becomes a low-pressure two-phase refrigerant. This low-pressure two-phase refrigerant flows into the outdoor heat exchanger 44 of the outdoor unit 40. The low-pressure two-phase refrigerant that has flowed into the outdoor heat exchanger 44 is evaporated and gasified by absorbing heat from air supplied from a blower (not shown). The low-pressure gas refrigerant flows out of the outdoor heat exchanger 44, passes through the four-way switching valve 47, and is sucked into the compressor 43 again.
A heating operation is performed by repeating the above refrigerant cycle.

  As described above, in the air conditioning system S, the advantages of the air conditioner (convection type indoor unit 41) and the advantages of the air conditioning apparatus 1A can be combined to complement each other, so that the temperature control of the air conditioning can be efficiently and effectively performed. Can be done automatically.

  During heating, air in the vicinity of the heat generating portion 22 is heated by conduction heat or radiant heat, and air that rises upward from below along the reflecting plate 23 through the gap between the reflecting plate 23 and the heat generating portion 22. The air from below is heated by the heat generating portion 22 while rising, and the above flow is continued.

  The heated air that has risen and reaches the ceiling has an increased flow velocity, and reaches a position considerably away from the air conditioner 1A along the ceiling surface. In addition, the air exchanges heat with the room air along with this movement, is cooled, descends, moves to the installation surface side, enters again from the lower part of the air conditioner 1A, and is heated and raised by the heat generating unit 22. In this way, the room air circulates and convects the entire room while being heated by the heat generating portion 22.

  In addition, the radiant heat radiated from the heat generating part 22 is emitted into the room from the front side of the air conditioner 1A, and the radiant heat reflected by the reflecting plate 23 passes through a gap formed in the heat generating part 22 in part. Since it is released into the room and propagates to those around it, the person around can directly feel the warmth. The radiant heat is effectively used to warm the wall, ceiling, installation surface F, etc., and the indoor air is indirectly heated by the warmed wall, ceiling, installation surface F, etc.

  Thus, since the air conditioning apparatus 1A repeats the reflection and release of radiant heat, the entire room is well heated by the radiant heat together with the heat moving by the convection of the air, and the air conditioning can be effectively performed. It becomes possible to reduce the amount of air blown by the fan of the inner heat exchanger 46 or to stop the fan, and consequently suppress or eliminate the draft feeling due to the air blown from the fan that is felt by those around. Can do.

  In the above-described cooling, unlike the case where heating is performed, the air is cooled by the heat generating portion 22, and thus the air flow along the heat generating portion 22 and the reflector 23 is directed downward from the top and cooled. Although the air flow is almost opposite to that in the case of heating, the air conditioning of the entire room can be effectively performed, and the draft feeling due to the air blown from the fans felt by those around can be suppressed. About a point etc., it is the same as that of the case of heating.

  Further, since the air conditioner 1A is incorporated in the refrigerant circuit of the air conditioner, the refrigerant is supplied from the air conditioner side, so that the air conditioner 1A does not require a device such as a compressor, and is controlled in conjunction with the air conditioner. Can also be performed.

  In this specification and the claims, the term “radiation” can be restated as “radiation”. In addition, the term “chimney effect” as used in the present specification covers the part of the side of the heat generating part, or covers all of the side of the heat generating part in a cylindrical shape to cover the air in the gap. Used to include the effect of increasing the flow velocity.

  The terms and expressions used in the present specification and claims are for illustrative purposes only, and are not intended to be limiting in any way. The features described in the present specification and claims and their There is no intention of excluding some equivalent terms and expressions. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
