临时用房室内热环境与围护结构热损失研究OA
Study on Indoor Thermal Environment and Heat Loss of Envelope Structure in Temporary Rooms
以北京冬奥会临时用房为研究对象,采用模拟方法,研究地面辐射供暖房间、散热器供暖房间的室内热环境与围护结构热损失.两种供暖房间人员活动区域的吹风感不明显,满足舒适度要求.地面辐射供暖房间的高度方向上空气温度梯度明显低于散热器供暖房间.散热器供暖房间在长度方向上的空气温度均匀性优于地面辐射供暖房间.在设定热源条件下,地面辐射供暖房间围护结构总热损失略高于散热器供暖房间.临时用房热损失主要由外窗、外门形成,应从提高外窗、外门保温性能入手,降低临时用房的供暖能耗.
Taking temporary buildings for the Beijing Winter Olympics as the research object,a simu-lation method was used to study the indoor thermal en-vironment and enclosure structure heat loss of floor ra-diation heating rooms and radiator heating rooms.The blowing sensation in the personnel activity area of the two types of heating rooms is not obvious,which meets the comfort requirements.The air temperature gradient in the height direction of the floor radiant heating room is significantly lower than that of the radiator heating room.The air temperature uniformity in the length direction of the radiator heating room is better than that of the floor radiant heating room.Under the set heat source conditions,the total heat loss of the enclosure structure in the floor radiant heating room is slightly higher than that in the radiator heating room.The heat loss of temporary rooms is mainly caused by external windows and external doors,and the thermal insulation performance of external win-dows and external doors should be improved to reduce the heating energy consumption of temporary rooms.
