【摘要】 通过理论分析阐述了空调用冷却水系统变流量运行的可行性.与只改变冷水机组和冷却水泵运行台数的运行管理方式相比较,冷却水系统通过水泵变频调速,实现变流量运行,其经济性相当显著.同时分析了变流量运行时附加设备的回收期.更多还原

【Abstract】 The paper analyses the cooling water system, and demonstrates that it is available to apply the variable flow water operation in the cooling water system. It compares the variable flow water operation with the operation that the number of the refrigerators and the cooling pumps is changed. By applying speed control by frequency converter in the cooling water system to verify the water flow, it testifies the remarkable economical efficiency. It also calculates the recycling period of the auxiliary equipment for the variable flow operation.更多还原
