摘　　要：机械新风系统作为超低能耗建筑满足室内环境的必要组成,其实际负荷与能耗关系到建筑整体系统能耗水平。本文结合当前严寒和寒冷地区超低能耗建筑中,由于实际开启时段差异造成的新风系统实新风热负荷及能耗计算偏差,提出计算修正,同时分析办公建筑及居住建筑中由于系统运行时间不同造成的负荷及能耗差异,为新风系统热负荷及能耗的设计计算提供参考。With the extremely low energy consumption,Ultra-low energy building has become an important direction of the construction development in recent years. The mechanical ventilation system has becoming a key factor that affecting the quality of indoor air and the overall energy consumption level of the building because of the high-level air tightness. This paper focuses on the impact of actual operating schedule when calculating the preheating load in cold and severe cold regions. Thus, a correcting calculation and difference analysis on mechanical ventilation analysis between office building and residential building will be proposed aiming at different operating schedule.
