| 摘 要： | 目前集成式蒸发冷凝冷水机组在地铁车站得到较广泛的应用,但对于该系统的实际运行状况研究较少。为了研究系统实际运行特点进而提高系统现有运行性能优化运行,对杭州市采用蒸发冷凝冷水机组和采用常规冷水机组的两座地铁站进行性能测试,分析蒸发冷凝冷水机组的能耗特点,分析室外温湿度对不同负载下蒸发冷凝机组性能系数(coefficient of performance,COP)的影响。当系统负载较低时COP的主要影响因素是进风空气相对湿度,满负载时压缩机COP同时受干球温度和相对湿度影响,当室外空气焓值增加时压缩机COP随之降低。同时对两座地铁站的运行能耗进行实测分析并研究两者的能耗运行特性。

| Abstract: | A performance test on a metro station in Hangzhou was conducted using an evaporative condensing chiller and a conventional chiller, and the energy consumption characteristics of the evaporative condensing chiller were analyzed. The influence of outdoor temperature and humidity on the coefficient of performance (COP) of the evaporative condensing unit under different loads was analyzed. The results show that the COP of a subway station using the evaporative condensing chiller was higher than that of the conventional chilled water system. When the system load was low, the main influencing factor of COP was the relative humidity of the inlet air. At full load, the compressor COP was affected by both the dry bulb temperature and the relative humidity. When the outdoor air enthalpy increases, the compressor COP decreases. |
