Embodiment Construction
[0026] The embodiment of the present invention firstly provides an air conditioner, including: a refrigerant circulation system formed by sequentially connecting a compressor 100 , an outdoor unit heat exchanger 200 and an indoor unit heat exchanger 300 . The supercooling tube group 400 is arranged downstream of the refrigerant flow path of the outdoor unit heat exchanger 200. The above-mentioned "downstream" refers to the refrigerant that is directly or indirectly connected to the outdoor unit heat exchanger 200 by the supercooling tube group 400 under the normal cooling state of the air conditioner. exit. In the cooling state, the refrigerant flows sequentially through the compressor 100, the outdoor unit heat exchanger 200, the subcooling tube group 400 and the indoor unit heat exchanger 300, and in the heating state, the refrigerant starts to circulate in the opposite direction from the compressor 100 . The subcooling tube group 400 includes: a main capillary 410 , a seco...
