空调水系统综合能效比的计算方法
Calculation method of energy efficiency ratio for air conditioning water systems
摘要：
以建筑全年逐时负荷为基础，提出了一种空调水系统全年综合能效比的计算方法。该计算方法分别考虑了建筑全年逐时负荷不断变化情况下空调主机及水泵的运行策略，以及主机在部分负荷工况下的能效比等因素，可更准确地计算出制冷机房内空调水系统主要设备耗电量。结合某夏季采用冷水机组制冷的定流量一级泵系统项目，介绍了以上计算方法的实际应用。

Abstract：
Based on the building all-year hourly air conditioning load, presents a calculation method, in which mainly considered are the operation strategy of water chiller units and water pumps when the hourly load changed, the energy efficiency ratio of the water chiller unit under the part load condition. This method can be used for calculating the power consumption of the main equipment in refrigerating plant room more accurately. Based on an example project with constant flow distribution with primary pump chilled water system, states a practical application of this calculation method.
