Problems solved by technology

The air return pipe is mostly made of aluminum pipes. Because of the low surface temperature, it is easy to absorb the surrounding moisture. The capillary pipes are copper pipes. Electrochemical corrosion is prone to occur between the copper and aluminum pipes in a humid environment. Corrosion of the aluminum pipes will easily lead to refrigeration in the refrigeration system agent leak
[0004] The capillary is longer than the return pipe. The traditional design is to coil the non-parallel segment capillary at the inle

Abstract

The invention discloses a high-efficiency heat regenerator with an inner layer coated with a film, and relates to the technical field of vapor compression type refrigerating systems. The device comprises a capillary tube and an air return tube. The capillary tube comprises a capillary tube inlet section and a capillary tube outlet section. The air return tube comprises an air return tube inlet section and an air return tube outlet section. The air return tube outlet section is sequentially connected with a compressor, a condenser, the capillary tube and an evaporator. The outlet section of the evaporator is connected with the air return tube inlet section to form a circulating refrigeration system. The circulating refrigeration system is filled with a refrigerant. The refrigerant flows out from the outlet end of the compressor, sequentially flows through the condenser, the capillary tube, the evaporator and the air return tube and finally flows into the inlet end of the compressor. The outer surface of the air return tube is covered with a plastic film, the risk of electrochemical corrosion between the air return tube and the capillary tube is reduced, and the capillary tube is arranged to be of a reciprocating folding structure, so that the heat exchange efficiency of the heat regenerator is improved.

Description

technical field [0001] The invention belongs to the technical field of vapor compression refrigeration systems, and in particular relates to an inner film-coated high-efficiency regenerator. Background technique [0002] The vapor compression refrigeration system is a closed circuit. The compressor drives the refrigerant to circulate in the condenser, capillary, evaporator, return pipe and other components in order to realize the transfer of heat. The parallel heat exchange part of the return pipe and the capillary is called refrigeration. The regenerator of the system, the refrigerant in the regenerator undergoes countercurrent heat exchange. Through countercurrent heat exchange, on the one hand, the subcooling degree of the refrigerant in the capillary tube is reduced, and on the other hand, under the heating effect of the capillary tube, the temperature of the return air pipe It is beneficial to improve the efficiency of the refrigeration system. [0003] Refrigerators a...
