我厂是六十年代设计,采用大气式凉水塔,塔下部有四台75m~2淋浇式冷凝器,均安装在车间屋顶上,配用170m~3/小时离心式水泵循环用水(见图1)。其优点是能够充分利用自然风力,冷凝效果很好。但在冬季气温较低,特别在春节前后,会出现以下一些情况: (1)因我厂生产季节性较强,冬季冷库热负荷很小平均为80000 Kcae/h(93.04KW),占设计负荷490000Kcae/h(569.87KW)16％左右。冬季开机,当继
Our factory is designed in the 1960s, using atmospheric cooling tower, the bottom of the tower has four 75m ~ 2 pouring pouring condenser, are installed in the workshop roof, equipped with 170m ~ 3 / hour centrifugal water pump cycle (see Figure 1). Its advantage is to make full use of natural wind, condensation effect is very good. However, in the winter, the temperature is low, especially during the Spring Festival, some of the following will occur: (1) Due to the seasonal production in our plant, the average heat load in cold storage in winter is 80000 Kcae / h (93.04 KW), accounting for the design load 490000Kcae / h (569.87KW) about 16%. Winter boot, when the next
