Summary

During the electricity defrosting of air cooler, some issues would arise, such as that temperature field would be damaged, energy would be lost , the refrigeration load would be increased, so a set of electric isolation device was designed. At the typical operating condition that cold storage temperature is -18°C, electric defrosting of air cooler was studied after using the partition device. Then the questions that how the partition board to influence the cold storage temperature, the temperature field around the air-cooler and the consumption of electric heating defrosting was studied through comparing the experimental data whether the defrosting partition device was used or not.The results indicate that after using the partition device, the variation of cold storage temperature is reduced, the maximum change is decreased by 5°C; ambient temperature uniformity around the air cooler is improved, the maximum change is increased by 10°C; defrosting energy consumption is reduced by 1/3. So the energy utilization rate for electricity defrosting was improved when partition board was applied.
