空气侧经济器(Air-side economizer)由于其具有节能效果显著、可提高室内空气品质等优点越来越受到行业内人们的关注。然而在我国，应用空气侧经济器的空调系统的实际可以达到的最大新风比往往远达不到全新风工况的100%。选择北京、上海、成都、西安和哈尔滨5个城市，利用eQUEST能耗模拟软件针对1栋商场建筑的典型模型，对焓差控制、温差控制和固定温度控制3种控制策略下的空气侧经济器在不同可达新风比下的节能量进行了模拟计算，并对计算结果进行对比，分析了不同气候、不同控制策略下，空气侧经济器的节能效果对最大可达新风比的敏感性。

As air-side economizer has a significant energy saving rate, the ability to improve IAQ and other advantages, it is being paid more and more attention by industry insiders. However, many air-side economizers implemented in China could not achieve 100% ratio of maximum introduced outdoor air to total supply air. Therefore, this study employed the dynamic building energy simulation program eQUEST to compute the energy savings of a prototype shopping mall model applying economizers under dual-enthalpy, dual-temperature and fixed temperature control strategies in Beijing, Shanghai, Chengdu, Xi’an and Harbin to analyze how the energy-saving ratio(ESR) of economizer re-sponds to variable ratio of maximum outdoor air to supply air.
