摘要
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。
Establishes the calculation models of energy consumption of the water chiller and pump in fan-coil unit air coditioning chilled water system, and calculates the total energy consumption under different supply water temperatures. Under the calculation condition of this article, when the head of water pump is between 15 m and 33.2 m, and the chilled water supply temperature is 7 ℃ and the supplyreturn water temperature difference is 5 ℃, the system energy consumption is the lowest; when the head of water pump is between 33.2 m and 40 m, and the chilled water supply temperature is 6 ℃ and the supplyreturn water temperature difference is 6.17 ℃, the system energy consumption is the minimum.
