| 摘 要： | 提出一种在设计阶段对冷水机组方案进行优化配置的方法.首先,冷水机组的能耗计算简化为制冷机的实际制冷量和冷却水进口温度两个独立变量的函数.进一步,通过建筑动态负荷计算获得全年冷负荷频率特性以及相应的室外湿球温度分布,其中湿球温度决定了冷却水最低进口温度.最终,计算出各种冷水机组配置方案的全年以及不同冷负荷需求工况下的运行电耗,并得出最优化的节能方案.

| Abstract: | Proposes a method for selecting optimal chiller unit configuration in design phase, in which the energy consumption of chillers is simplified to the function of actual cooling capacity and entering water temperature of the condenser, then the all-year building load frequency distribution under different outdoor wet-bulb temperature that determines the minimum entering cooling water temperature is obtained by dynamic load calculation, and finally, calculates the all-year energy consumption and energy consump... |
