Problems solved by technology

[0003] Since the outdoor heat exchanger absorbs heat from the outdoor air, when the temperature around the outdoor heat exchanger is low, the water vapor in the air will condense into frost and adhere to the surface of the outdoor heat exchanger, affecting the heat transfer capacity of the outdoor heat exchanger. Decreased heating capacity, affecting people's comfort
[0004] In order to solve the defrosting problem of air conditioners, most air conditioners currently use four-way valve reversing control; when defrosting, the four-way valve is reversing, the outdoor heat exchanger releases heat, and the indoor heat exchanger absorbs heat; when the air conditioner is running refrigeration In the process of defrosting, since the frost at the bottom of the outdoor heat exchanger is difficult to remove, when the upper part has been defrosted, it must wait until the lower part of the heat exchanger is completely defrosted. The defrosting time is longer; in addition, some enterprises currently adopt the four-way valve non-reversing defrosting method, but the air supply temperature of the indoor unit is low during the defrosting process, and there is a risk of blowing cool air. Phenomena, the above-mentioned discomforts that people feel

Abstract

The invention relates to an air conditioner comprising an indoor heat exchanger, a first outdoor heat exchanger, a compressor, a throttling device and a four-way valve. The air conditioner is characterized by further comprising a second outdoor heat exchanger, a first two-way valve, a second two-way valve, a third two-way valve, a fourth two-way valve, a one-way valve, a first flow adjusting control part, a second flow adjusting control part and a two-position three-way change valve. The air conditioner can improve the heating amount at a lower-temperature environment and can continuously heat and rapidly and cleanly defrost; and the temperature fluctuation of an indoor environment is small and the comfort of a user is greatly improved.

Description

technical field [0001] The invention relates to an air conditioner and a control method thereof, and belongs to the technical improvement of an air conditioner that operates in a hot gas bypass and independent defrosting mode linked to the indoor air supply temperature and coil temperature. Background technique [0002] During the heating operation of the heat pump air conditioner, the refrigerant exchanges heat with the outdoor air through the outdoor heat exchanger, absorbs heat from the outdoor air and evaporates, and the compressor compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant vapor, which enters the room. The heat exchanger releases heat; through the indoor heat exchanger, the heat is released to heat the indoor air, so that people can enjoy a more comfortable environment. [0003] Since the outdoor heat exchanger absorbs heat from the outdoor air, when the temperature around the outdoor heat exchanger i...
