Refrigeration method of refrigeration system, control device and compression refrigeration system

The invention provides a refrigeration method of a refrigeration system, a control device and a compression refrigeration system, relates to the technical field of mine air conditioners, and aims to reduce the energy consumption of the refrigeration system. The cooling capacity of cooling water conveyed to the underground is utilized, the condenser of the refrigerating system is cooled, and meanwhile supplied air flowing through the evaporator is pre-cooled. Moreover, an automatic control strategy is designed, the flow of cooling water flowing through the condenser is distributed, and the rotating speed of a motor of the compressor is reduced under the condition that the air supply cooling load is met, so that the compressor operates under the working condition of lower energy consumption, and the energy consumption of the system is saved. 本发明提供了一种制冷系统的制冷方法、控制装置及压缩制冷系统，涉及矿井空调技术领域，用以降低制冷系统的能耗。本发明利用了输送至井下的冷却水的冷却能力，对制冷系统的冷凝器进行冷却，同时对流经蒸发器的送风进行预冷。并且，本专利发明设计了自动控制策略，分配流经冷凝器的冷却水流量，在满足送风冷负荷的条件下，降低压缩机的电机转速，使得压缩机在更低能耗的工
