A frost-free heat exchange system for cold storage

Abstract

The invention belongs to the refrigeration field of refrigeration houses, and discloses a frostless heat exchange system for a refrigeration house. The system comprises a fan, a heat exchanger, a moisture absorption assembly, a windward port and an air supply opening, wherein the windward port is connected with the refrigeration house to be treated, so that return air in the refrigeration house tobe treated enters the heat exchange system from the windward port; the fan rotates so as to enable the return air in the refrigeration house to be treated to enter the heat exchange system from the windward port; the moisture absorption assembly is arranged on the windward port, and is used for dehumidifying and drying the return air entered from the windward port, so that the dew point temperature of the dehumidified return air is lower than the temperature of the surface of the heat exchanger, and the surface of the heat exchanger is prevented from frosting; the heat exchanger is used for cooling the return air dehumidified through the moisture absorption assembly; and the air supply opening is connected with the refrigeration house to be treated, and is used for returning the return air treated by the heat exchanger into the refrigeration house to be treated. Through the frostless heat exchange system for the refrigeration house provided by the invention, the defrosting cycle is greatly prolonged, the heat exchanger is prevented from frosting, and the problems brought by defrosting are solved.

Description

technical field [0001] The invention belongs to the refrigeration field of cold storage, and more specifically relates to a frost-free heat exchange system for cold storage. Background technique [0002] Cold chain logistics is an important link in the food industry and the biomedical industry, and has a great impact on the quality of life of the people. Among them, cold storage is an important link in cold chain logistics, but the problem of frost on the heat exchanger in the cold storage is serious, which will seriously reduce the efficiency of the refrigeration system and even cause failure. [0003] In order to solve the above problems, there are two main solutions: use low energy consumption and high efficiency technology for defrosting, or suppress the occurrence of frosting. The currently used or proposed defrosting technologies mainly include manual defrosting, electric heating defrosting, hot air defrosting, water flushing defrosting, compressed air defrosting, mic...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a frost-free heat exchange system for cold storage. By setting its key component, the hygroscopic component, the air is cooled by the heat exchanger before being cooled. Dehumidification and drying, the purpose is to avoid frosting on the heat exchanger, thereby avoiding defrosting or reducing the frequency of defrosting, thereby solving the technical problems of low overall efficiency of the cold storage and large temperature fluctuations of the cold storage caused by defrosting
