摘　　要：水蓄冷系统能够提供满足热湿分控空气处理模式中新风除湿要求的低温水,将两者组合构成的复合系统,既能获得较好的室内空气品质,又能扩大蓄冷温差,达到更好的移峰填谷效果.文章对比分析了复合水蓄冷前后热湿分控空调系统的运行能耗和运行费用,并与2种常规空调系统进行了比较.结果显示,热湿分控空调系统能耗均低于常规热湿耦合空调系统,能耗分别为常规热湿耦合空调系统的95%和88%;由于存在蓄冷槽损失,各系统与水蓄冷槽组成复合系统后,能耗均略有上升,但运行费用均有明显降低,运行费用分别是原系统的81%、61%和48%,而且具有显著的移峰填谷效果;与复合蓄冷槽的常规热湿耦合系统相比,热湿分控空调系统能有效增加蓄冷槽的蓄冷温差,由传统的5℃温差蓄冷,变成15℃温差蓄冷.The chilled water storage system （CWS） can provide low temperature chilled water which satisfies fresh air dehumidification demand of the temperature and humidity independent controllingair conditioning system（THIC） ,and the system compositing CWS and THIC （THIC ＋ CWS） can not only obtain better indoor air quality（ IAQ）, but also extend temperature difference of CWS, and achieve better effect of power grid peak load shift. The system operation energy consumption and cost before and after compositing THIC and CWS is analyzed, and then compared with those of the two conventional air conditioning systems the fan-coil unit with fresh air system（FCU-FA） and the compositing CWS and FCU-FA（ FCU-FA ＋ CWS）. The results show that the energy consumption of THICs is 95% and 88% of conventional FCU-FA, and energy consumption of THICs ＋ CWS rises slightly as chilled water tank loss, and the operating costs are 48% and 61% of THICs. THICs ＋ CWS system can effectively increase the chilled water temperature difference of water storage tank compared with the conventional FCU-FA ＋ CWS,from 5 ℃ to 15 ℃, and has significant peak load shift effect.
