The invention discloses a refrigerant circulation system and refrigeration equipment. The refrigerant circulation system comprises a compressor, a condenser and an evaporator; an air-returning pipe is connected between the compressor and the evaporator, and a capillary pipe is connected between the condenser and the refrigerant evaporator; the refrigerant circulation system further comprises a connecting pipe and a control valve, the control valve comprises a flow-in end, a first flow-out end and a second flow-out end, the flow-in end is communicated with the compressor, the first flow-out end is communicated with the condenser, the second flow-out end is communicated with one end of the connecting pipe, and the other end of the connecting pipe is communicated with the capillary pipe. According to the refrigerant circulation system and the refrigeration equipment, the control valve and the connecting pipe are arranged, so that liquid-state refrigerants in the capillary pipe and the air-returning pipe are evaporated by high-temperature refrigerants in the evaporator, and 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, 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] At present, when the compressor of our refrigerator is started, since the refrigerant in the refrigerant circulation system has not undergone heat exchange, the temperature is relatively low, and the refrigerant in the return air pipe and 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] To achieve the above object, the refrigeran...
