The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner and an oil return control method thereof. The air conditioner and the oil return control method thereof aim to solve the problem that the exhaust temperature of a compressor is too high due to the oil return mode of the existing air conditioner. The air conditioner comprises a compressor, a heat exchanger and an oil separator, wherein a first oil return branch and a second oil return branch are arranged between an air inlet of the compressor and an oil outlet of the oil separator inparallel, the first oil return branch directly makes the air inlet of the compressor connect with the oil outlet of the oil separator, and the second oil return branch makes the air inlet of the compressor with the oil outlet of the oil separator after flowing near the heat exchanger. The oil return control method comprises the following steps that1, outdoor ambient temperature is acquired; 2, according to the outdoor ambient temperature, the first oil return branch or the second oil return branch is selectively communicated to adaptively change the oil return temperature of the lubricating oil, so that the reflux temperature of the lubricating oil can always be matched with the exhaust temperature required by the compressor.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and an oil return control method thereof. Background technique [0002] With the continuous improvement of people's living standards, people have also put forward higher and higher requirements for the living environment. In order to maintain a comfortable ambient temperature, air conditioners have become an essential device in people's lives. Generally, an air conditioner includes an indoor unit, an outdoor unit, and a circulation loop for connecting the indoor unit and the outdoor unit. The refrigerant in the air conditioner continuously exchanges heat between the outdoor unit and the indoor unit through the circulation loop, thereby achieving the effect of changing the room temperature. . At the same time, the refrigerant needs the auxiliary function of the compressor in the process of gas-liquid change, and some existing compressors m...
