| Abstract: | Hot gas defrosting applied in cold storage was presented and defrosting process investigated by experiment was studied under different cold storage temperatures. The influerence of hot gas defrosting on cold storage was analyzed through the aspects of cold storage temperature, quantity of condensate, temperature distribution variation and the working condition of refrigeration system. The results show that hot gas defrosting has advantages of short defrosting-time and little influence on cold storage, temperature and so on. |
