Abstract

The invention discloses a refrigerant circulation system and refrigeration equipment. The refrigerant circulation system comprises a compressor, a condenser and an evaporator, refrigerants in the compressor pass through the condenser and the evaporator sequentially and then return to the compressor, and an air-returning pipe is connected between the compressor and the evaporator; the refrigerant circulation system further comprises a heating piece which is connected with the air-returning pipe. According to the embodiment, the heating piece is arranged to evaporate liquid-state refrigerants in a capillary pipe and the air-returning pipe, so that the refrigerants sucked into the compressor when the compressor is started are gaseous-state refrigerants; accordingly, the liquid-state refrigerants can be prevented from being sucked into the compressor, the liquid impact phenomenon can be prevented from occurring in the compressor, and the normal operation of the compressor is facilitated, and the service life of the compressor can be prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerant circulation system and refrigeration equipment. Background technique [0002] When the compressor of the existing refrigerator is started, since the refrigerant in the refrigerant circulation system has not been subjected to heat exchange, the temperature is relatively low, and the refrigerant in the air return pipe and the capillary of the compressor may be liquid refrigerant. The compressor starts to suck air at the moment of starting, so that the liquid refrigerant in the return pipe and capillary tube is sucked into the compressor, causing liquid hammer to occur in the compressor, thereby affecting the life of the compressor. Contents of the invention [0003] The main purpose of the present invention is to provide a refrigerant circulation system, aiming at avoiding liquid hammer phenomenon in the compressor. [0004] In order to achieve the above obje...
