Problems solved by technology
However, when the evaporating temperature is low and the condensing temperature is high (especially in winter in the north), the discharge temperature of the compressor (that is, the temperature of the refrigerating fluid flowing out of the refrigerating fluid outlet of the compressor) may increase and the working efficiency may increase. Lowering the problem
If the compressor works in this state for a long time, it will cause serious damage to the compressor itself

Temperature control equipment for a compressor, a compressor component, and a refrigeration system. The temperature control equipment comprises a temperature detection device, used for detecting the temperature of refrigeration fluid at a refrigeration fluid outlet of the compressor; a liquid supply pipeline, used for supplying a liquid refrigerant to the compressor; a liquid supply valve, arranged in the liquid supply pipeline and used for controlling the flow of the liquid refrigerant supplied to the compressor; and a control device, used for receiving the temperature value detected by the temperature detection device and controlling the liquid supply valve according to the temperature value, so that the flow of the liquid refrigerant is increased when the temperature value is greater than a first threshold value and the flow of the liquid refrigerant is reduced when the temperature value is smaller than a second threshold value; where the second threshold value is not greater than the first threshold value. The temperature control equipment and the temperature control method can avoid the problem of the reduced work performance of the compressor caused by rising of the exhaust temperature and guarantee the stable and high-efficiency operation of the compressor.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a temperature control device for a compressor, a compressor assembly, a refrigeration system and a temperature control method for a compressor. Background technique [0002] As a key component in refrigeration equipment, the compressor has received extensive attention for its working efficiency and stability. In typical refrigeration equipment, the compressor operates in conjunction with the condenser, throttle valve, and evaporator to complete the refrigeration cycle. However, when the evaporating temperature is low and the condensing temperature is high (especially in winter in the north), the discharge temperature of the compressor (that is, the temperature of the refrigerating fluid flowing out of the refrigerating fluid outlet of the compressor) may increase and the working efficiency may increase. Lowering the problem. If the compressor works in this state for a long time, it w...
