The role of precision chillers in various industries

In the precision chiller, the heat absorbed from the evaporator and refrigeration compressor and in the pipeline is transferred to the surrounding medium to take away, and the refrigerant high-pressure superheated vapor recondenses into a liquid. In the cooling process of the chiller, the condenser plays a role in outputting heat energy and condensing the refrigeran
