双温冷库经济运行分析

Analysis on Economical Operation for Cold Storage Building with Two Temperature Levels

许多冷库都具有两个温度不同的库区,即高温库和低温库。本文对这类冷库的经济运行进行分析,着重结合某冷库的实验测试结果,对低温库双级压缩制冷低压级带高温库蒸发系统的运行与低温库、高温库分别开机单独运行进行分析比较,探讨这些运行方式的可行性和经济性。

Many cold storage buildings have cold rooms with two temperature levels,i.e.cooling rooms and freezing ones. This paper analyzes their economical operation conditions. Some experimental results are given out. The emphasis is put on those where there are single stage compressors and double stage ones. The comparisons are made on the operational cost when one compressor is used for two rooms with different temperature levels and two compressors are separately used for different rooms with different temperature levels.The feasibility and economics are discussed.
