空调冷冻水系统大温差设计的能耗分析

Analysis on Energy Consumption of Large Temperature Difference in Air Conditioning Chilled Water System

从水泵、制冷机及空调系统的基本理论出发，分析了空调冷冻水系统大温差设计的能耗，并提出了冷冻水系统大温差设计的使用场合。由于系统虽节约了水量，减少水泵扬程及耗电量，但蒸发温度下降，冷水机组制冷效率下降，能耗增大，所以一般适用于要求水泵扬程H＞31.7m的高层建筑空调系统。

Analyses the energy consumption in air conditioning chilled water systemdesigned for large temperature difference. The system, though can reduce water flow, pumpinghead and powr correspondingly, decreases evaporate temperatureand chiller efficiency.Therefore, it is commonly appied to high-rise buildings air conditioning system that demandspumping head more than 31. 7m.
