Abstract：To address the issues of significant heat loss,high energy consumption and large temperature field fluctuations during the thermal defrosting process of cold air fans in cold storage,a cold air fan equipped with a heat isolation device is proposed,and its performance under different initial defrosting temperatures and defrosting amounts is studied through experiments.The results show that after installing the heat isolation device,the temperature fluctuation in the environmental chamber is significantly reduced,the defrosting energy consumption is greatly decreased,the temperature distribution is more uniform,and the defrosting time is shortened.When the frosting amount is 3.0 kg,the device saves energy by 57.41%to 64.08%.When the frosting amount is 4.5 kg,energy savings range from 58.1%to 61.42%.This device effectively suppresses the temperature fluctuations inside the cabin during the defrosting stage,shortens the defrosting time,saves defrosting energy consumption,and significantly improves the storage quality and operational efficiency of the cold storage.
