空调冷冻水温的选择及节能效果研究

A Study of the Chilled Water Temperature and the Energy-saving Effect in Air Condition

本文分析了制冷主机、冷冻水泵在不同冷冻水出水温度和温差下的能耗特性,计算分析了末端设备在不同负荷特性下表冷器的热力特性及阻力特性,综合表述了冷冻水温度及温差的选择要素。

This paper analyzes the energy - dissipating character of the refrigerating main machine and the chilled water pump in different effluent chilled water temperature and temperature difference, calculates the thermodynamic characteristics and resistance characteristics of the surface cooler in the terminal in different loading and summarizes the key factors to decide the chilled water temperature and temperature difference.
