Embodiment Construction
[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0049] The invention provides a defrosting control method of an air conditioner.
[0050] according to figure 1 Shown is a structural schematic diagram of a heat pump air conditioner. The heat pump air conditioner includes a compressor 10, a four-way valve 20, an outdoor heat exchanger 30, a throttling component 40, and an indoor heat exchanger 50, wherein the throttling component 40 may be an electronic expansion valve. During the heating process of the air conditioner, the high-temperature and high-pressure refrigerant discharged from the exhaust port 11 of the compressor 10 flows into the indoor heat exchanger 50 after being reversed by the four-way valve 20, and flows into the room through the air duct system of the indoor heat exchanger 50. Provide continuous heat, at the same time, the refrigerant is condensed...
