摘　　要：在超低能耗住宅项目的供暖空调设计方案中,外墙热桥对平均传热系数的影响、冷热源方案、新风机组选型及卫生间通风方案对建筑能耗影响极大。通过热桥模拟、冷热源系统方案对比、新风量排风量对比计算等方案分析讨论以上问题,验证了设计方案的实施效果。In the heating and air conditioning design scheme of ultra-low energy residential projects,the influence of external wall thermal bridges on the average heat transfer coefficient,cold and heat source schemes,selection of fresh air units,and bathroom ventilation schemes have a significant impact on energy consumption calculation.This article analyzes and discusses the above issues through thermal bridge simulation,comparison of cold and heat source system schemes,and comparison calculation of fresh air volume and exhaust air volume,and verifies the implementation effect of the design scheme.

关 键 词：超低能耗建筑 热桥模拟 冷热源系统 新风量
