Abstract

The invention belongs to the technical field of air conditioners, and particularly provides an air conditioning unit with a compressor cooling branch and a compressor cooling control method. The air conditioning unit with the compressor cooling branch and the compressor cooling control method aim to solve the problem that an existing mode for reducing the exhaust temperature of a compressor is notgood. For the reason, the air conditioning unit comprises a main circulation loop, the compressor, an outdoor coil and an indoor coil, wherein the compressor, the outdoor coil and the indoor coil arearranged on the main circulation loop, the compressor is provided with an air supplementing port, at least a part of the compressor cooling branch is attached to the compressor so that a refrigerantin the compressor cooling branch can primarily cool the compressor outside the compressor, one end of the compressor cooling branch is connected with the air supplementing port, the other end of the compressor cooling branch is connected with a liquid pipe so that the refrigerant in the compressor cooling branch can enter the compressor to secondarily cool the compressor. According to the air conditioning unit with the compressor cooling branch and the compressor cooling control method, through primary cooling, pre-cooling is achieved, and then through secondary cooling, the temperature of thecompressor is further reduced, so that the cooling effect of the compressor is improved to the greatest extent conveniently, and the heat exchange efficiency of the air conditioning unit is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner unit with a compressor cooling branch and a compressor cooling control method. 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-conditioning units have become an essential device in people's lives. At the same time, people have put forward higher and higher requirements for the heating efficiency of air conditioning units; generally, the heating efficiency of heat pump air conditioning units is generally low when the outdoor ambient temperature is low, which makes it difficult to Meet the heat exchange needs of users. Specifically, when the external ambient temperature is low, the evaporation pressure of the air-conditioning unit is relatively low, resul...
