Solution dehumidification system and operation method for dehumidification in cold storage hallway

Abstract

The invention discloses a solution dehumidification system aimed at the dehumidification of cold storage corridors, which includes a liquid storage tank, and the liquid storage tank is respectively connected to a first liquid-gas heat exchanger in a refrigerating room and a second liquid-gas heat exchanger in a freezing room through a branch circuit The first heat exchanger communicates with the first dehumidifier, the outlet of the first dehumidifier communicates with the first liquid-gas heat exchanger through a branch, and communicates with the solution regenerator through another branch, and the first dehumidifier communicates with the first liquid-gas heat exchanger through another branch. The second liquid-gas heat exchanger communicates with the second dehumidifier, the outlet of the second dehumidifier communicates with the second liquid-gas heat exchanger through a branch, and communicates with the solution regenerator through another branch, the first dehumidifier The air inlet is connected to the fan, and the air outlet is respectively connected to the cold storage hallway and the second dehumidifier through pipes. The invention suppresses the occurrence of frosting in the cold storage at the root, does not affect the normal operation of the refrigeration system of the cold storage, ensures the product quality of the refrigerated objects, and satisfies the economical and energy-saving performance of the cold storage operation.

Description

technical field [0001] The invention relates to a refrigeration and air conditioning system and its operation, in particular to a solution dehumidification system and an operation method for the dehumidification of a cold storage hallway. Background technique [0002] At present, with the continuous improvement of people's living standards and the vigorous development of online shopping, my country's cold chain logistics industry has entered a stage of rapid development, and various cold storages play a vital role in it. In my country, the energy consumption of cold storage accounts for more than 70% of the energy consumption of the entire cold chain logistics industry, and its unit energy consumption level has a large gap compared with developed countries. Therefore, reducing the energy consumption level of cold storage is of great significance to the cause of energy conservation and emission reduction in my country. [0003] Generally speaking, all kinds of cold storages ...
