某冷冻库电热融霜和热气融霜功耗对比分析

Comparative analysis of power consumption of electric defrosting and hot vapor defrosting in a frozen storage

通过分析制冷和融霜运行流程,对3个工况下某冷冻库的电热融霜和热气融霜功耗进行对比分析。结果表明,热气融霜是较为节能的融霜方式,其融霜功耗降低20%以上,制冷系统运行功耗降低12%以上。

By analyzing the operation process of refrigeration and defrosting,the power consumption of electric defrosting and hot vapor defrosting in a frozen storage is compared under three working conditions.The results show that the hot vapor defrosting is more energy-saving,its defrosting power consumption is reduced by above 20%,and the opera-tion power consumption of refrigeration system is reduced by above 12%.
