The working process of the embodiment of the present invention will be described in detail below in conjunction with FIG. 2:

The cold water of the refrigerating unit is transported through the water supply pipeline to the air cooler installed in the air intake lane of the high-temperature mine, and the air cooler cools the air in the high-temperature mine, and the cold water is cooled by the air After the device, it flows back into the refrigerating unit through the return pipeline.

The liquid dehumidifier installed in the air intake lane of the high-temperature mine dehumidifies the air, and the heat released during the dehumidification process is absorbed and taken away by the dehumidification liquid, and the dehumidification liquid becomes a dilute solution, and the dilute solution enters the dehumidifier Before the reduction system, heat exchange is carried out with the high-temperature concentrated solution from the dehumidifier reduction system, and the dilute solution is preheated, which can effectively reduce the heat supply of the heat pump.

The heat pump system absorbs the heat released by the condensation of the refrigeration unit and indirectly provides the energy required by the desiccant reduction system. The dilute solution is heated and reduced to the high-temperature concentrated solution by the desiccant reduction system. The dilute solution flowing out of the dehumidifier undergoes heat exchange, and the heat-exchanged concentrated solution enters the liquid dehumidifier for dehumidification and forms a circulation.
