However, many air-side economizers implemented in China could not achieve 1% 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 responds to variable ratio of maximum outdoor air to supply air. air-side economizer; free cooling; maximum ratio of outdoor air to supply air; shopping mall; energy simulation (air-side economizer) % 1995 (water-side economizer) 15 m (free cooling) [1]
