摘要
通过把我国北方某地区4 000 m2二层高温冷库改造成为2 300 t的高温(0±3)℃冷库及1 000 t的低温(-18±1)℃冷库的过程,分析了制冷工质的选择以及进行了围护结构的校核和负荷计算,并依据冷库实际情况对满足设计工况下的螺杆机、活塞机、多联机的节能效果做了比较,结果表明在冷库负荷变化大或冷库低负荷运行时间长的情况下所选机器中多联机最节能.
By reconstructing in China northern region 4 000 m^2 high temperature cold storage into 2 300 tons of cold storage at high temperature （0 ± 3）℃ and 1 000 tons of cold storage at low temperature （ - 18 ± 1 ） ℃ , this paper analyzes the choice of refrigerants, checks the external walls and calculates the load of cold storage, according to practical situation of cold storage compared the screw rod machine the piston machine and the parallel machines about effect of energy conservation under the designed operating mode , the result showes that the parallel machines are best about energy conservation than others when the cold storage load changed frequently or the cold storage load last in a low level.
