Summary

In order to reduce the effect of defrosting heat on the cold storage temperature change during defrosting process, a heat insulation defrosting device is additionally provided to the air cooler in the storage,and the experimental study on the defrosting process was carried out. The results showed that in the defrosting processes with and without heat insulation, the temperature of the upper area in the storage changed greatly. The temperature changes relatively small during the defrosting process with heat insulation,and the overall fluctuating temperature is 3.2°C lower than that without heat insulation. In the meantime, the defrosting time with heat insulation is shortened by nearly 300s, which proves that the insulation defrosting device can stabilize the storage temperature and shorten the defrosting time in the defrosting process.
