摘 要：对国内有代表性的冷冻食品加工企业全年耗电变化趋势、各个设备系统耗电所占比例进行了计量和调查统计，统计结果显示：全年制冷系统耗电比例为65.6%左右，照明系统耗电比例为29.1%左右,其它部分仅占5.3%左右；而1~3月份照明系统占37.9%、速冻间33.6%、冷冻库20.1%、冷藏库6%，4~5月份和9~12月份速冻间占40.3%、照明系统占35.1%、冷冻库占28.4%、冷藏库占9.1%，6~8月份速冻间占31.6%、冷冻库占26.6%、照明系统占22.7%、冷藏库占9.6%，照明系统节电与速冻间、冷冻库同等重要。调查了企业现行氨制冷系统运行中普遍存在的问题现象，分析了导致系统能效偏低的主要原­因、节能渠道和节能 空间，为企业提高系统能效和节能减排工作提供参考。

Abstract The annual energy consumption trend and the energy consumption proportion of equipment in typical domestic frozen food processing enterprises were investigated. The results show that the energy consumption of refrigeration systems, lighting systems, and the others is 65.6%, 29.1%, and only about5.3%of the total year energy consumption, respectively. From January to March, the energy consumption proportion of lighting systems, the quick-freezing rooms, freeze rooms, and cold storage rooms is 37.9%, 33.6%, 20.1%, and6%, respectively while in April and May and from September to December, the proportion above is35.1%,40.3%,28.4%,9.1%,respectively. From June to August, the proportion is 22.7%,31.6%,26.6%, and9.6%, respectively. The data show that energy-saving of light

ing systems also is important. In addition, the existing problems in ammonia refrigeration systems were analyzed. 2Refs. In Chinese.
