为了研究夜间机械通风对高校图书管建筑空调系统能耗和室内热舒适性的影响,选取湖南省某高校图书馆为研究对象。用EnergyPlus模拟了不同夜间通风工况时的能耗、墙体内壁面温度和PMV,并进行了对比分析。结果显示,通风量在57n/h时空调系统具有较好的节能效果,5月、6月、9月和10月存在不同的最佳夜间通风工况,最佳夜间通风工况时,供冷季节空调系统可减少耗电量2. 71kW·h/（m2·a）,节能率为10. 0%; 5月、6月、9月和10月墙体内表面月平均温度可分别降低1. 6℃、0. 6℃、0. 9℃和1. 7℃,并且室内热舒适性均有不同程度改善。

To investigate the effectiveness of night mechanical ventilation on air - conditioning energyconsumption and indoor thermal comfort of college library buildings, a university library in HunanProvince was selected to study. The energy consumption, inner surface temperature of wall and PMV（Predicted Mean Vote） at different night ventilation conditions were simulated by EnergyPlus. The resultsshow that air conditioning system can achieve distinct energy - saving effect when ventilation volume is 5~7 n,h - 1, and there were different optimum nigh...
