给出了风机盘管空调冷水系统中冷水机组与水泵能耗的计算模型,计算了不同冷水供水温度下的系统总能耗。在文中计算条件下,水泵扬程为15～33.2m时,冷水供水温度7℃、供回水温差5℃情况下,系统能耗最小;水泵扬程为33.2～40m时,冷水供水温度6℃、供回水温差6.17℃情况下,系统能耗最小。
The calculation model of energy consumption of water chiller and water pump in air-condition chiller system of fan-coil unit is given, and the total system energy consumption of different chilled water supply temperature is calculated. Under the calculation conditions, the system consumes the least energy when the pump head is 15 ~ 33.2m, the cold water supply temperature is 7 ℃ and the supply and return water temperature difference is 5 ℃. When the pump lift is 33.2 ~ 40m, the cold water supply temperature is 6 ℃. Backwater temperature difference of 6.17 ℃ case, the system minimum energy consumption.
