空调系统冷水大温差运行特性分析

Performance Analysis of Chilled Water Large Temperature Difference Operation For Air-conditioning system

本文通过对空调系统冷水大温差运行时制冷系统的能耗及有效能进行计算分析 ,并与名义工况下空调系统相比较 ;同时 ,分析了冷水泵的能耗 ,提出了节能运行的最佳冷水出口温度及进出口温差。

The article focuses on calculating and analyzing the energy consumption and exergy in an air-conditioning system of large temperature difference operation.Compared with the standard air-conditioning system,the optimal temperature of chilled water supply and temperature difference can be deduced from the point of view of saving energy.At the same time,the energy consumption of the chilled water pump and the characteristics of the energy saving are analyzed and give a good reference to the optimal operation and design of the air-conditioning system in our country.
