| 摘 要： | 对冬季建筑物南壁面的太阳辐射强度、南外窗和南外墙的内壁温进行了逐时计算，并结合冬季太阳辐射的特点进行了逐时热负荷计算。结果表明在冬季供暖空调标准工况下，太阳辐射使南外墙内表面壁温全天整体小幅上升，并使南外墙的逐时热负荷较北外墙降低约20％；在节能达标居住建筑的南向房间，中午时段内室内空气所吸收的南外窗太阳辐射得热量已超过该房间的逐时热负荷，供暖空调系统在冬季运行时有必要充分利用这部分能量。

| Abstract: | Solar irradiance in south wall of buildings and inner surface temperature of south windows and wall in winter has been calculated hourly. Based on the property of solar irradiation in winter and the calculating method of unsteady heat load of air conditioner in summer, calculating and analyzing of unsteady heat load in south rooms of building was made. This will provide reference for heating and air conditioning systems of buildings to utilize solar energy possibly in winter. |
