  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

<First Embodiment>
Initially, the structure and operation | movement outline | summary are demonstrated about the air conditioner of 1st Embodiment of this invention using FIGS. 1-4. FIG.1 and FIG.2 is a schematic block diagram of an air conditioner, respectively, and shows a state during cooling operation and heating operation. FIG. 3 is an external perspective view of the outdoor unit of the air conditioner, and FIG. 4 is a perspective view of the outdoor unit with the exterior cover removed.

  The air conditioner 1 is a separate type air conditioner that includes an outdoor unit 10 and an indoor unit 30 as shown in FIGS. 1 and 2.

  The outdoor unit 10 is installed on, for example, an outdoor floor surface, and includes a rectangular box-shaped casing 11 composed of synthetic resin parts and sheet metal parts (see FIG. 3). The compressor 12, the switching valve 13, the expansion valve 14, the outdoor blower 15, the outdoor heat exchanger 16, and the like shown in FIGS. 1, 2, and 4 are accommodated in the housing 11.

  The switching valve 13 is a four-way valve for switching the refrigerant flow direction in different operation modes such as cooling operation and heating operation. As the expansion valve 14, a valve whose opening degree can be controlled is used.

  The outdoor blower 15 is a combination of a propeller fan provided adjacent to the inner wall of the housing 11 and a motor that rotates the propeller fan. The housing 11 is provided with an inlet (not shown) and an outlet 11b. The outdoor heat exchanger 16 is disposed in the vicinity of the outdoor fan 15. When the outdoor blower 15 is driven, the outside air sucked into the housing 11 from the outside through the suction port passes through the outdoor heat exchanger 16, and heat exchange is performed between the outdoor heat exchanger 16 and the outside air. Is called.

  The outdoor unit 10 is connected to the indoor unit 30 through two refrigerant pipes 17 and 18. Liquid refrigerant flows through the refrigerant pipe 17, and a thinner pipe than the refrigerant pipe 18 is used. Therefore, the refrigerant pipe 17 is sometimes referred to as “liquid pipe”, “narrow pipe”, or the like. A gaseous refrigerant flows through the refrigerant pipe 18, and a thicker pipe than the refrigerant pipe 17 is used. Therefore, the refrigerant pipe 18 may be referred to as “gas pipe”, “thick pipe”, or the like, for example. For example, HFC R410A or R32 is used as the refrigerant.

  Regarding the refrigerant pipes 19 and 20 inside the outdoor unit 10, the refrigerant pipe 19 connected to the refrigerant pipe 17 is provided with a two-way valve 21, and the refrigerant pipe 20 connected to the refrigerant pipe 18 is provided with a three-way valve 22. It is done. The two-way valve 21 and the three-way valve 22 are closed when the refrigerant pipes 17 and 18 are removed from the outdoor unit 10 to prevent the refrigerant from leaking from the outdoor unit 10 to the outside. When the refrigerant needs to be recovered from the outdoor unit 10 or the entire air conditioner 1, the recovery is performed through the three-way valve 22.

  The indoor unit 30 is installed near, for example, an indoor wall ceiling, and includes a housing 31 made of a synthetic resin component. The casing 31 houses the indoor blower 32, the indoor heat exchanger 33, and the like shown in FIGS.

  The indoor blower 32 is a combination of a cross flow fan that extends horizontally in the horizontal direction along the shape of the housing 31 and a motor that rotates the fan. The housing 31 is provided with a suction port and an air outlet which are not shown. The indoor heat exchanger 33 extends in the horizontal direction like the cross flow fan, and is configured by combining three pieces (indoor heat exchangers 33A, 33B, 33C). The three indoor heat exchangers 33 are arranged so as to cover the top and front of the crossflow fan of the indoor blower 32. When the indoor blower 32 is driven, the indoor air sucked into the housing 31 through the suction port passes through the indoor heat exchanger 33, and the indoor heat exchanger 33 exchanges heat with the indoor air. .

  FIG. 1 shows a state in which the air conditioner 1 is performing a cooling operation or a defrosting operation. At this time, the compressor 12 circulates the refrigerant in a cooling mode, that is, in a circulation mode in which the refrigerant discharged from the compressor 12 first enters the outdoor heat exchanger 16. The refrigerant circulates in the direction of the arrow drawn close to the refrigerant pipes 17 to 20 in FIG.

  The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 12 enters the outdoor heat exchanger 16 where heat exchange with the outside air is performed. The refrigerant dissipates heat to the outside air and condenses. The refrigerant that has condensed into a liquid is decompressed by the expansion valve 14 from the outdoor heat exchanger 16. The decompressed refrigerant is sent to the indoor heat exchanger 33, expands to a low temperature and low pressure, and lowers the surface temperature of the indoor heat exchanger 33. The indoor heat exchanger 33 whose surface temperature has dropped absorbs heat from the room air, and thereby the room air is cooled. After the heat absorption, the low-temperature gaseous refrigerant returns to the compressor 12. The air flow generated by the outdoor blower 15 promotes heat dissipation from the outdoor heat exchanger 16, and the air flow generated by the indoor blower 32 promotes heat absorption of the indoor heat exchanger 33.

  FIG. 2 shows a state where the air conditioner 1 is performing a heating operation. At this time, the switching valve 13 is switched, and the refrigerant flow is reversed from that during the cooling operation. The compressor 12 circulates the refrigerant in a circulation mode during heating, that is, in a circulation mode in which the refrigerant discharged from the compressor 12 first enters the indoor heat exchanger 33. The refrigerant circulates in the direction of the arrow drawn close to the refrigerant pipes 17 to 20 in FIG.

  The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 12 enters the indoor heat exchanger 33 where heat exchange with the indoor air is performed. The refrigerant dissipates heat to the room air, and the room air is warmed. The refrigerant that has radiated heat and condensed to become liquid is decompressed by the expansion valve 14 from the indoor heat exchanger 33. The decompressed refrigerant is sent to the outdoor heat exchanger 16 and expands to a low temperature and low pressure, thereby lowering the surface temperature of the outdoor heat exchanger 16. The outdoor heat exchanger 16 whose surface temperature has dropped absorbs heat from the outside air. After the heat absorption, the low-temperature gaseous refrigerant returns to the compressor 12. The air flow generated by the indoor blower 32 promotes heat dissipation from the indoor heat exchanger 33, and the air flow generated by the outdoor blower 15 promotes heat absorption by the outdoor heat exchanger 16.
