Résumé

Hot liquid defrosting is a new method of defrosting. This paper introduces experimental facilities on hot liquid defrosting.The influence of hot liquid defrosting on cold storage was analysed through the aspects of cold storage temperature, defrosting -time and the working condition of refrigeration system. The results show that hot liquid defrosting can recover cold energy by heat transfer between high-pressure liquid refrigerant and frost. After the defrosting process, temperature in cold storage increases considerably. The temperature still reduces during the defrosting process under no-load experimental conditions when the temperature is higher than -5 degree at the beginning of the experiment, which implies that the hot liquid defrosting program can be applied to the quick-freezing device.
