摘要
以冬季北方地区是否可以建造地下冷库的问题进行了讨论.选择两个相同外形尺寸、墙体厚度、贮存品种的冷库,分别逐月计算了-18℃冷藏库、5℃高温库的热流量;并对相同冷间温度下,地上、地下两种形式冷库热流量、机器设备选择、初投资、运行费用方面进行了分析比较.研究得出相同冷间温度的地上、地下两种冷库在初投资、设备选择方面相差不大,但高温库建在地下,低温库建在地上可减少年运行费用.
This paper discusses on building the underground cold storage in the northern area with rich natural cold sources in winter . Chooses two identical profile size, wall thickness, storage varieties of cold storage, calculated monthly the heat flow for - 18 ℃ cold storage, 5 ℃ high-temperature storage; at the same cold storage temperature, ground and underground cold storage heat flow, equipment selection, initial investment and operating costs are analyzed and compared. Result is that the ground and underground are similar at the same cold storage temperature in initial investment and equipment selection , but this method of the high-temperature storage is built under the ground and the cold storage is built on the ground can reduce operating costs.
