循环水箱一般是用来为有特殊要求机组提供冷却水的。由于机组、水泵、管路长期运行后 ,大量水垢会淤积于水箱底部 ,部分还会附着于冷却盘管表面 ,当系统重新启动时 ,这些水垢又回到系统中进行循环。既影响系统正常运行 ,又降低冷却效果。常规的解决办法是使用软化水或加过滤器 Circulating water tank is generally used to provide cooling water for special requirements of the unit. As the chillers, pumps, and pipes run for a long time, a large amount of scale will accumulate on the bottom of the tank and some will adhere to the surface of the cooling coil. When the system is restarted, these scales will return to the system for circulation. Both affect the normal operation of the system, but also reduce the cooling effect. A common solution is to use demineralized water or add filters
