中央空调系统质调节运行方案模拟分析

The Simulation and Analysis about Constant Flow Control Operation of Central Air-conditioning

冷水机组作为空调系统中的主要耗能设备,实际运行中的绝大多时间是处于部分负荷。本文针对上海某公共建筑的空调系统进行了实例分析,提出了分阶段变冷水温度的运行方案。利用De ST-c软件对冷水机组进行了全工况模拟,预测了其节能效果。

Chiller as the major energy-consuming equipment in central air-conditioning system, the majority of its actual operating time is in part load. This paper gives the operating scheme about changing the chilled water temperature in different time for the central air-conditioning system of a public building in Shanghai. Finally a simulation about the chillers in its whole operating time is made to verify our scheme＇s energy saving effect.
