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。
On the basis of the hourly load of the whole building, a calculation method of annual energy efficiency of air conditioning system is put forward. The calculation method respectively considers the operation strategy of air-conditioning main engine and pump under the condition of hourly load change of the whole year and the energy efficiency ratio of main engine under partial load condition, which can more accurately calculate the air-conditioner water system Main equipment power consumption. Combined with the project of a constant flow primary pump system using a chiller unit for cooling in summer, the practical application of the above calculation method is introduced.
