[0027] use Figure 1 to Figure 4 , the air conditioner 200 according to the first embodiment of the present invention will be described.
[0028] figure 1 A configuration diagram showing the refrigeration cycle of the air conditioner 200 of the first embodiment.
[0029] figure 1 The air conditioner 200 shown is a domestic room air conditioner. The air conditioner 200 includes: an indoor unit 110 for regulating the temperature in a building; an outdoor unit 100 for receiving / radiating heat from the air outside the building; Side connection piping 114 . Inside the indoor unit 110, an indoor heat exchanger 111 and a cross-flow fan 112 are provided. Inside the outdoor unit 100 are provided a compressor 101 , a four-way valve 102 , an outdoor heat exchanger 103 , a propeller fan 105 , a main expansion valve 104 , a sub-expansion valve 3 , and a first heat exchange unit 4 .
[0030] This system is composed of a main channel 1 and an auxiliary channel 2. The main channel 1 pas...

[0055] use Figure 5 , Figure 6 , the air conditioner 220 according to the second embodiment of the present invention will be described.
[0056] Figure 5 A configuration diagram showing the refrigeration cycle of the air conditioner 220 of the second embodiment.
[0057] The difference between the air conditioner 220 of the second embodiment and the air conditioner 200 of the first embodiment is that the secondary flow path 2 (second flow path B) between the first heat exchange part 4 and the flow path junction 5 passes through The second heat exchange unit 6 connected to the compressor 101 ; and the liquid phase side distributor 30 and the gas phase side distributor 31 are provided before and after the outdoor heat exchanger 103 .
[0058] The second heat exchange part 6 has a shape in which the sub-flow path 2 is in contact with the surface of the compressor 101 , and heats the refrigerant in the sub-flow path 2 passing through the surface of the compressor 101 with a ...

[0068] use Figure 7 , the air conditioner 230 according to the third embodiment of the present invention will be described.
[0069] Figure 7 A configuration diagram showing the refrigeration cycle of the air conditioner 230 of the third embodiment.
[0070]The air conditioner 230 of the third embodiment is a refrigeration cycle in which the sub expansion valve 3 and the sub channel 2 are removed from the air conditioner 220 of the second embodiment, and the third heat exchange unit 10 is provided instead of the first heat exchange unit 4 . The outlet of the gas-phase side distributor 31 is connected to the four-way valve 102 after passing through the first check valve 11 , the third heat exchange unit 10 , and the fourth heat exchange unit 16 . The flow path from the outlet of the gas-phase side distributor 31 to the inlet of the four-way valve 102 via the first check valve 11 , the third heat exchange unit 10 , and the fourth heat exchange unit 16 corresponds to the seco...
