摘要：以夏热冬冷地区的杭州市西湖吉鸿未来社区幼儿园为例，采用CFD软件进行幼儿园建筑通风模拟，以典型污染物代表CO2为标志物，分析室内CO2浓度场的变化情况。结果显示，过渡季节，幼儿园教室能够通过开窗的自然通风方式改善室内空气质量；冬夏季幼儿园教室应采用上部机械通风方式的新风净化系统，解决冬夏季幼儿园教室内CO2浓度偏高的问题。

Abstract：This paper starts with the kindergarten building of West Lake Jihong Future Community in hot summer and cold winter area，CFD software is used to simulate the ventilation of kindergarten buildings，and research is conducted on the representative of typical pollutant CO2. Change condition of indoor CO2 concentration field is analyzed. The results show that in transition season，kindergarten classrooms improve indoor air quality through natural ventilation by opening windows. Kindergartens should adopt fresh air purification system with upper mechanical ventilation in winter and summer to solve the problem of high CO2 concentration in the classrooms.
