The general principle of design and layout of display cooler refrigeration system

The general principle of design and layout of display cooler refrigeration system 1. The determination of the type of refrigerant mainly decides whether to use ammonia (R717) or Freon. Generally speaking, if it is a large-tonnage, large-bay display cooler for aquatic products and low-temperature meat display cooler, and the control accuracy is not high, you can use the ammonia display cooler. ...
