为了解决冷风机融霜时周围温度场遭破坏﹑能量损失﹑制冷负荷增加等问题，设计了一套电动隔断装置。在库温为_18℃的这一典型工况下，对增加隔断装置后，冷风机电热融霜情况进行了研究，并与未增加隔断装置的实验数据进行了对比，讨论了电热融霜时，有无融霜隔断装置对融霜过程中冷库库温变化﹑融霜结束时冷风机周围温度场分布及融霜能耗的影响。结果表明；增加隔断装置后，融霜对冷库库温影响变小，库温最大变化量降低了5℃；冷风机周围的温度均匀性得到提高，最大温差降低了10℃；融霜能耗降低了1∕3。应用隔断装置可以提高电热融霜的能量利用率。

During the electricity defrosting of air cooler, some issues would arise, such as that temperature field would be damaged, ener_gy 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 ℃, 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 con_sumption 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 ℃; ambient temperature uniformity around the air cooler is improved, the maximum change is increased by 10℃; defrosting energy consumption is reduced by 1 ∕3.So the energy utilization rate for electricity defrosting was improved when partition board was applied.
