Compared with the gas defrosting,the cold liquid refrigerant defrosting system has larger capacity of refrigeration,less influence on the efficiency of heat exchanger fins,less fluctuations in temperature.

Study on the Energy Saving and Defrosting Energy Analyse of the Dual Glass Island Case;

Investigation of the Frosting Performance and Improvement of the Defrosting Method for an Air-cooler under Low Temperature Condition;

The State-of-the-art of Forsting and Defrosting of Evaporators in Display Cabinets;

An Investigation of Improvement of defrosting system for open refrigerated food display cabinets;

In this paper, the current status of researches on display cases are introduced, including the heat load ofdisplay cases, CFD simulation computation of air curtain, frost or defrost properties of evaporators and optimizationdesign of display cases.

Eventually,defrost cycle is required and mitigate the performance degradation due to the frost in frost condition.

Experimental investigation of hot gas defrosting in cold storage;

This thesis treats of the two plans of the hot gas defrosting in the refrigeration system of showcases in super marketsa,nd analyzed the property of energy saving of hot gas defrosting qualitatively.
