Working Principle

The entire working principle process can be roughly divided into three parts: water circulation system, refrigeration circulation system, and main control system. The water circulation system is also a part that directly reflects the function of industrial chillers. It transfers cold water to the equipment that needs to be cooled, absorbs the heat from the equipment, and then transfers it back. A refrigeration cycle system is the process of cooling cold water that absorbs heat. The refrigerant sublimates and then compresses, carrying the heat from the cold water outdoors for heat dissipation. The main control system is part of power control and internal structural component control.
