全年制冷如何解决冬季室外冷冻站水系统防冻和室内加湿困难问题

For Refrigeration and How to Solve the Winter Outdoor Refrigeration Station Antifreeze Water System and Indoor Humidifying Difficult Problem

我们都知道冬季(尤其是长江以北),为了防止新风机组、空调机组的表冷盘管和加热盘管以及相关管道的冻裂,都必须采取措施如新风预热或放尽停止工作的加热和表冷管内剩水等等。那么,对于全年制冷工况下冬季室外冷冻站的设备,如冷水机组、水泵及冷冻水、冷却水系统管路,在都不能放尽水的情况下,如何防止冻裂事故呢?另外,冬季采用高压喷雾加湿,喷口附近积水严重如何解决?就某项目实例,对这方面的问题及如何预防进行简单阐述。

We all know that the winter （especially north of the Yangtze river）, In order to prevent air units, air conditioning units table cold tube frosty and heating coil and related piping. All measures must be taken, such as fresh air preheat or try to stop working heating and cooling tube with water, etc. So, For cooling conditions throughout the year winter outdoor refrigeration station equipment, such as chiller, water pump and chilled water and cooling water system piping, in the case of can＇t put water, how to prevent frost crack accident？ In addition, Winter use high-pressure spray humidification, vent water how to solve the serious？ In this paper, a project example, the problems and how to prevent briefly.
