摘　　要：通过建立模型,优化了建筑体形,以降低建筑外区围护结构负荷;通过设定不同的外区组合方式,寻找合理的外区冷热单风道变风量系统划分方式;分析了冬季工况下围护结构散热与太阳辐射得热的相对关系,以及发生室内过热的概率,并探讨了外区冷热单风道变风量系统应对及缓解室内过热的措施。By establishing a model,the building shape is optimized to reduce the load of the envelope structure in the perimeter zone of the building.By setting different combination modes of the perimeter zone,a reasonable division of the cold and hot single duct VAV system in the perimeter zone is to be pursued.The relative relationship between the heat dissipation of the building envelope and solar radiation heat gain in winter as well as the probability of indoor overheating are also analysed.The measures to deal with and alleviate the indoor overheating of the cold and hot single duct VAV system in the perimeter zone are discussed.
