摘要：The typical residential building in Changzhou City, Jiangsu Province was selected for natural ventilation measurement during the transitional season, the plum rainy season, summer and winter. In this paper, SF6 is used as the tracer gas, and tracer gas decay method was selected to obtain the air change rate in the room under each measuring condition. EnergyPlus(EP) was used to calculate the single-zone and multizone air change rate which can be compared with the measured values respectively. It was found that the calculated values of single-zone model were generally small and the errors were large. And the calculated values of multi-zone model have a significant reduction in error after considering the equivalent infiltration area. In addition, the effective infiltration area will be different due to the existence of the thermal expansion coefficient for different seasons.
