A magnetic refrigeration module includes a housing, low and high temperature inflow paths, low and high temperature outflow paths, and first and second intermediate flow paths. The housing houses a magnetic working substance, and forms a flow path. The low and high temperature inflow paths carry heating medium into first and second ends of the flow path. First and second spaces are formed between the first and second ends and the low and high temperature inflow paths. The low and high temperature outflow paths receive the heating medium from the first and second ends of the flow path. The first and second intermediate flow paths communicate with the low and high temperature inflow paths and the first and second spaces. The first and second intermediate flow paths expand heating medium flow from the low and high temperature inflow paths to the first and second spaces.

The present invention relates to a wet evaporation-based cold concentration system, which is mainly applied to the technical field of air conditioners, and particularly applied to the technical field of heat-source tower heat-pump air conditioners. By utilizing a wet evaporation theory, a low-temperature low-concentration anti-freezing solution is enabled to contact low-temperature air in a wet evaporator to perform the heat and mass transfer, and water in the anti-freezing solution is vaporized at a low temperature into the air, thereby obtaining the high-concentration anti-freezing solution. By reasonably utilizing the concentration pool and the storage pool, the low-concentration anti-freezing solution is separated from the high-concentration anti-freezing solution, thereby achieving a purpose of simultaneously concentrating and storing the anti-freezing solution
