Embodiment Construction

[0045] see in conjunction Figure 1 to Figure 6 As shown, according to the embodiment of the present application, the air conditioner includes an indoor unit and an outdoor unit, the indoor unit includes an indoor air inlet 1, an indoor heat exchanger 2, an indoor fan 3 and an auxiliary heater 4, and the outdoor unit includes a compressor 7, an outdoor Heat exchanger 8, four-way valve 9, gas-liquid separator 10 and throttle valve 6.

[0046] The auxiliary heater 4 is located between the indoor air inlet 1 and the indoor heat exchanger 2, and the auxiliary heater 4 is set outside the indoor heat exchanger 2. When the air conditioner is in the defrosting mode, the auxiliary heater 4 is used for heating The air that enters the indoor heat exchanger 2 through the tuyere is heated.

[0047] The air conditioner sets the auxiliary heater 4 between the indoor air inlet 1 and the indoor heat exchanger 2, so when defrosting the outdoor heat exchanger 8, the auxiliary heater 4 can be tu...

Abstract

The present application provides an air conditioner and a defrosting control method thereof. The air conditioner includes an indoor air inlet (1), an indoor heat exchanger (2), an indoor fan (3) and an auxiliary heater (4). The auxiliary heater (4) is located between the indoor air inlet (1) and the indoor heat exchanger. (2), and the auxiliary heater (4) is set outside the indoor heat exchanger (2), when the air conditioner is in the defrosting mode, the auxiliary heater (4) is used to (2) The air is heated. According to the air conditioner of the present application, during the defrosting process of the outdoor heat exchanger, it is possible to avoid the problem that the refrigerant absorbs heat indoors and causes the indoor temperature to drop, thereby reducing user comfort.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to an air conditioner and a defrosting control method thereof. Background technique [0002] The current household air conditioners realize cooling or heating through the circulation of refrigerant. As the air conditioner is turned on, the refrigerant begins to circulate inside the air conditioning system. In the cooling condition, the low-temperature and low-pressure refrigerant in the heat exchanger of the internal unit absorbs heat from the room; in the heating condition, the high-temperature and high-pressure refrigerant in the heat exchanger of the internal unit releases heat to the room. [0003] In the heating condition, the high-temperature and high-pressure refrigerant in the heat exchanger of the indoor unit releases heat to the room. When the air conditioner is heating for a long time, a frost layer will be formed on the heat exchanger of the outdoor un...
