Heat exchange cooling system

Abstract

The invention discloses a heat exchange cooling system. The heat exchange cooling system comprises a compressor, an evaporator, an expansion valve and a condenser which are sequentially connected end to end through a refrigerant pipeline to form a circulation loop, wherein the refrigerant pipeline comprises a first refrigerant pipeline used for communicating the compressor with the evaporator, and a second refrigerant pipeline used for communicating the expansion valve with the condenser. The heat exchange cooling system further comprises a heat transfer element, wherein the heat transfer element is connected with the first refrigerant pipeline and the second refrigerant pipeline respectively, and is capable of conducting the heat of a refrigerant in the second refrigerant pipeline to a refrigerant in the first refrigerant pipeline, so that the temperature of the refrigerant in the second refrigerant pipeline is lowered, the evaporation efficiency of the refrigerant is increased, and refrigeration energy consumption is reduced; and moreover, the ungasified liquid-state refrigerant in the first refrigerant pipeline can absorb heat to be gasified, and the liquid impact generated by the ungasified liquid on the compressor is reduced, so as to prolong the service life of the compressor.

Description

technical field [0001] The invention relates to a freezer, in particular to a heat exchange cooling system on the freezer. Background technique [0002] In places such as supermarkets, chain stores, and restaurants, it is often necessary to use freezers to store foods that require low-temperature preservation. A freezer generally includes a cabinet body and a refrigeration system installed on the cabinet body. Existing freezer refrigeration systems are generally composed of compressors, condensers, expansion valves, evaporators and other components, and the above components are connected from end to end through pipelines conveying refrigerant to form a circulation loop. The compressor compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gas and sends it to the condenser. When the high-temperature and high-pressure gaseous refrigerant flows through the condenser, it dissipates heat to the surrounding air and condenses ...

AI Technical Summary

Problems solved by technology

In addition, there will still be part of the liquid refrigerant in the refrigerant coming out of the evaporator that has not been vaporized, so that some liquid droplets are mixed in the gaseous refrigerant. If the liquid droplets enter the compressor, it will cause liquid shock to the compressor and cause the compressor to run. When the noise increases, it will shorten the service life of the compressor. If the content of liquid droplets in the gaseous refrigerant entering the compressor can be reduced, it will have a positive effect on improving the service life of the compressor.
