Application Analysis of the Pharmaceutical Purification and Low Temperature Air-conditioning and Refrigeration System

This paper introduces the structure and principle of purification and air-conditioning system,and analyzes the cooling and defrosting modes from aspects of technique application and energy saving.Defrosting is the key link of low-temperature purification air-conditioning system.The system mentioned in this paper adopted double air-conditioning boxes.Each box is equipped with separate refrigeration system and is able to cool and defrost alternately,thus to meet the demand of manufacturing technique to the environment.
