Description

  The present invention relates to a temperature control device and an air conditioner in an air conditioner installed in a building such as a commercial building.

  As an air conditioner provided in a building such as a commercial building or a private house, an air conditioner provided with an indoor unit that supplies cold air indoors and an outdoor unit that condenses refrigerant is generally used. The outdoor unit has a built-in heat exchanger (condenser) in the housing, and condenses the high-temperature refrigerant evaporated in the indoor unit for generating cold air by the heat exchanger. The condensed refrigerant becomes a liquid cooled to a predetermined temperature, and is sent to the indoor unit through a pipe line.

  In many cases, outdoor units are installed outdoors with good sunlight, and particularly in the summer, they tend to be exposed to direct sunlight. Under such circumstances, there is a problem that the thermal efficiency of the outdoor unit is lowered and the power consumption is also increased. Therefore, conventionally, an apparatus has been proposed in which a net is attached to a frame assembled around an outdoor unit, and the entire outdoor unit is covered with the net (see Patent Document 1). According to this, since the outdoor unit is in a cool shaded environment covered with a net, it can be expected to efficiently condense and liquefy the refrigerant with low power consumption.

Utility Model Registration No. 3171945

  However, in the above prior art, there are the following problems due to the mounting mode of the net. In other words, the outdoor unit needs to release the heat extracted from the room to the atmosphere, but since the entire outdoor unit is covered with the net, the released heat tends to accumulate inside the net. Therefore, the space covered with the net becomes high temperature, and hot air circulates to the intake port of the outdoor unit, so that there is a problem that the thermal efficiency of the outdoor unit is lowered and the power consumption is also increased.

  Accordingly, an object of the present invention is to provide a temperature control device and an air conditioner in an air conditioner that can improve the thermal efficiency and save power without being affected by the heat released from the outdoor unit.

  A temperature control device for an air conditioner according to the present invention is an indoor unit that is installed in a room of a building and supplies cold air generated by the heat of vaporization of the refrigerant to the room, and is installed outside the building and performs condensation of the refrigerant. An outdoor unit, and the outdoor unit has an intake port for sucking air into the one side surface, and an exhaust port for discharging air containing heat taken from the room into another side surface different from the one side surface A temperature adjusting device in the air conditioner that adjusts the temperature of the air sucked into the air intake of the air conditioner having a housing formed with an infinite number of meshes, and the air outlet and the exhaust A mesh member that covers the air inlet, and a frame member to which the mesh member is attached.

(Embodiment 1)
First, an overall configuration of an air conditioner according to an embodiment of the present invention will be described with reference to FIG. Hereinafter, one horizontal direction is defined as an X direction, a direction orthogonal to the X direction in a horizontal plane is defined as a Y direction, and a direction orthogonal to the XY plane is defined as a Z direction. The air conditioner 1 harmonizes the air in the room 2a of a building 2 such as a commercial building, and includes an indoor unit 3 and an outdoor unit 4. The indoor unit 3 and the outdoor unit 4 are connected via a pipe 5 through which a refrigerant such as chlorofluorocarbon circulates.

  FIG. 2 is a block diagram showing an outline of the air conditioner 1. Here, the case where the room 2a is cooled by the air conditioner 1 is illustrated. The indoor unit 3 is installed in the room 2 a and includes an evaporator (evaporator) 6 and a fan 7. The evaporator 6 has fins for heat dissipation, and evaporates the low-temperature and low-pressure liquid refrigerant sent from the outdoor unit 4 through the pipe 5. When the refrigerant evaporates by evaporation, the heat taken from the room 2a is transmitted to the refrigerant. The fan 7 supplies the air in the vicinity of the evaporator 6, which has become a low temperature due to the transfer of heat to the refrigerant, to the room 2 a (arrow a shown in FIG. 1). The refrigerant containing heat is sent to the outdoor unit 4 through the pipe 5.

  The outdoor unit 4 is installed outside, and includes a compressor 9, a heat exchanger (condenser) 10, a fan 11, and an expansion valve 12 inside a housing 8 (FIG. 3). In FIG. 3, the housing 8 is supported from below by a flat support base 13. The compressor 9 compresses the refrigerant containing heat sent from the indoor unit 3 via the pipe 5. The compressed refrigerant changes to a high-temperature and high-pressure liquid. The heat exchanger 10 includes fins for heat dissipation. The fin is in a state of lower temperature than the refrigerant because the heat of the surface is taken away by the air blown by the fan 11. The heat exchanger 10 takes heat from the compressed refrigerant and condenses it. The expansion valve 12 expands the condensed refrigerant. The refrigerant changes to a low-temperature and low-pressure liquid by adiabatic cooling that occurs during the expansion process. The refrigerant that has become a low-temperature and low-pressure liquid is sent again to the indoor unit 3 through the pipe 5. Thus, the air conditioner 1 is installed in the room 2a of the building 2 and supplies the cold air generated by the heat of vaporization of the refrigerant to the room 2a, and is installed outside the building 2 to condense the refrigerant. And an outdoor unit 4.

  In FIG. 3, an air inlet 8 a for sucking air (outside air) into the outdoor unit 4 is formed on one side surface A of the housing 8. Further, on the other side B opposite to the one side A, there is formed an exhaust port 8b through which air including heat extracted from the room 2a is discharged. Air sucked into the housing 8 through the air inlet 8a (arrow b shown in FIG. 5B) passes through the heat exchanger 10. At this time, air becomes high temperature by heat exchange. The air containing heat is discharged out of the outdoor unit 4 through the exhaust port 8b (arrow c shown in FIG. 5B). In addition, the exhaust port 8b may be formed in the upper surface of the housing | casing 8, for example. As described above, the casing 8 constituting the outdoor unit 4 includes an intake port 8a for sucking air into one side surface A and heat taken from the room 2a into another side surface B different from the one side surface A. An exhaust port 8b for discharging air is formed.

  Next, with reference to FIG.4 and FIG.5, the temperature control apparatus (temperature control means) 14 in the air conditioner 1 is demonstrated. The temperature adjustment device 14 adjusts the temperature of the air taken into the outdoor unit 4 through the intake port 8 a and includes a frame member 15 and a net 16. For convenience, the illustration of the net 16 is omitted in FIG. In FIG. 4A, the frame member 15 is grounded on the support base 13 and has a substantially rectangular parallelepiped base portion 15a disposed on both sides outward in the Y direction of the side surface A on which the air inlet 8a is formed. The support base 13 and the frame member 15 are fastened and fixed by screwing bolts 17 from above the base portion 15a. That is, the base portion 15a and the bolt 17 function as a fixing means (first fixing means) for fixing the frame member 15 to the support base 13 that supports the housing 8 from below.

  In each base portion 15a, a first extension portion 15b and a second extension portion 15c extending in the vertical direction are formed at a predetermined interval. The upper ends of the first extension part 15 b and the second extension part 15 c are located further above the upper surface of the housing 8. The first extending portion 15 b extends in the vertical direction from a position in front of the side surface A of the housing 8 (FIG. 4A). The second extending portion 15 c extends in the vertical direction from a position behind the side surface A of the housing 8. Therefore, as shown in FIG. 5B, the air inlet 8a is located between the first extension part 15b and the second extension part 15c when the housing 8 is viewed from the side.

  A first erection part 15d extending in a substantially horizontal direction is installed over the upper ends of the first extension part 15b and the second extension part 15c. The connecting portion between the first extending portion 15b and the first erection portion 15d is rounded. A second erection part 15e extending in a substantially horizontal direction is provided over the upper portion of the housing 8 at the upper end of each second extension part 15c. Further, between each of the first extending portions 15b, a rod-like third erection portion 15f extending in a substantially horizontal direction from a plurality of (here, two) positions having different height directions, An erection part 15g is erected. The frame member 15 includes the base 15a, the first extension 15b, the second extension 15c, the first installation part 15d, the second installation part 15e, the third installation part 15f, and the fourth extension. It is configured to include the erection part 15g. The frame member 15 is formed of a metal such as SUS, for example.

  4 (b), 5 (a), and 5 (b), the net 16 is formed by weaving a dark thread having air permeability such as a cold chill in a net shape, and covers the intake port 8a. It is attached from the surface of the member 15. The net 16 needs to be attached to the frame member 15 so as not to cover at least the exhaust port 8b. The net 16 is specifically attached by driving a fixing tool (not shown) such as a nail having a head having a size larger than the inner size of the mesh to a predetermined portion of the frame member 15. Thus, the net 16 is a net-like member that has an infinite number of meshes and covers the intake port 8a among the intake port 8a and the exhaust port 8b, and is attached to the frame member 15. The net 16 may be a synthetic resin having an infinite number of meshes. In short, any net-like member may be used as long as it has innumerable meshes, air permeability is ensured, and direct incidence of sunlight on the intake port 8a can be suppressed.

  By attaching the net 16 to the frame member 15, the air inlet 8 a is opened to one side surface A of the housing 8 and the space T (FIG. 5B) surrounded by the net 16. Thereby, air (outside air) is sucked into the intake port 8a through the space T. The net 16 is sucked toward the housing 8 by the suction force from the air inlet 8a, but the movement toward the housing 8 is restricted by the third erection part 15f and the fourth erection part 15g. As a result, the interference between the net 16 and the intake port 8a is prevented, and the space T is maintained. That is, the frame member 15 functions as a space forming means for forming a predetermined space T between the side surface A of the housing 8 in which the air inlet 8 a is formed and the net 16. If the space T is secured, the structure of the frame member 15 may be arbitrary. For example, the third erection part 15f and the fourth erection part 15g may be omitted.

  As described above, the following effects can be obtained by covering the intake port 8 a with the net 16 and opening the intake port 8 a in the space T surrounded by the side surface A of the housing 8 and the net 16. it can. That is, in the summer, the space T is in a shaded environment and is at a cool temperature lower than the outside temperature under the sun exposed to the sun S (FIG. 1). Therefore, since low-temperature air is sucked from the intake port 8a, the outdoor unit 4 can condense the refrigerant with high power consumption with less power consumption and further liquefy it.

  In winter, the air conditioner 1 mostly heats the room 2a. However, since the outdoor unit 4 needs to take in heat from the outside air, it is desirable that the air sucked from the intake port 8a is warm. Here, the space T has a certain hermeticity, and sunlight can slightly enter the space T through the mesh of the net 16. Further, since the net 16 serves as a windshield, it is difficult for cold wind to enter the space T, and the net 16 is somewhat warmed by absorbing sunlight. That is, in winter, the space T is in an environment where it is warmer than the outside temperature. Therefore, since relatively warm air is sucked from the intake port 8a, the outdoor unit 4 can evaporate the refrigerant with low power consumption and heat efficiency.

  Thus, by covering the intake port 8a with the net 16 attached to the frame member 15, the temperature of the air sucked into the intake port 8a can be adjusted. That is, the frame member 15 and the net 16 constitute a temperature adjusting device 14 (temperature adjusting means) that adjusts the temperature of the air sucked into the intake port 8a.

  As described above, according to the air conditioner 1 and the temperature control device 14 in the first embodiment, it is possible to improve the thermal efficiency and save power. Further, since the net 16 does not cover the exhaust port 8b of the housing 8, it is possible to prevent a situation in which air containing heat released from the exhaust port 8b is sucked into the intake port 8a.

(Embodiment 2)
Next, a second embodiment will be described with reference to FIG. Components common to those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The second embodiment is different from the first embodiment in that the frame member 15A is directly attached to the housing 8 of the outdoor unit 4. For convenience, the illustration of the net 16 is omitted in FIG.

  The frame member 15A has a configuration in which the base portion 15a in the first embodiment is omitted. Openings 15c1 that open in the horizontal direction are formed at predetermined positions of the individual second extending portions 15c. In addition, a plurality of (here, two) openings 15e1 opened in the vertical direction are formed at predetermined positions of the second erection part 15e. The frame member 15A is fixed to the housing 8 by screwing the bolt 17A into the housing 8 through the openings 15c1 and 15e1. That is, the second extending portion 15c, the second erection portion 15e, and the bolt 17A function as fixing means (second fixing means) for fixing the frame member 15A to the housing 8. Note that the frame member 15 </ b> A may be fixed to the housing 8 by pressing the bolts 17 </ b> A against the surface of the housing 8.

  The temperature control device 14 and the air conditioner 1 in the air conditioner 1 according to the present invention are not limited to the embodiments described so far, and may be changed in design without departing from the spirit of the invention. For example, the curtain rail may be fixed to the frame member so as to cover the casing 8, and a net may be attached to the curtain rail so as to cover the intake port. In addition, the air conditioner in the present specification refers to a device that repeatedly compresses, dissipates, and expands refrigerant using an outdoor unit, such as a gas-type air conditioner that uses water as a refrigerant in addition to a refrigerator, a water cooler, and the like. It is a concept that includes.

  According to the present invention, it is possible to improve the thermal efficiency and save power without being affected by the heat released from the outdoor unit, which is particularly useful in the field of manufacturing an air conditioner.
