摘　　要：本文介绍了北京密云地区某弃用冷库的改造方案,具体的改造内容包括对库址、围护结构、自控系统及冷库设备方面的选取及安装。改造方案的核心是通过引入自然冷源并添加温湿度控制系统的方式来降低冷库的能耗并提高对果蔬的保鲜能力。冷库改造后,选取适宜的时间段进行为期一百天的改造冷库实际效果测试,测试记录了相同外部环境条件下改造库和旧地库的能耗总量等参数,测试结果表明在测试期内改造冷库的能耗节约为76.34%。This paper introduces the renovation plan of an abandoned cold storage in Miyun of Beijing.The specific reconstruction includes the selection and installation of storage site,maintenance structure,automatic control system and equipment.The core of the reconstruction plan is to reduce the energy consumption problem and enhance the preservation ability of the storage by adding natural cooling source and temperature and humidity control system.After the cold storage renovation is completed,a 100-day practical effect test is carried out,and the total energy consumption and other parameters of the reconstructed storage and the old underground storage which are under the same circumstances are recorded.The results of test show that the energy saving rate during the 100-day test period is up to 76.34%.
