问:在围护结构中,门窗对空调降温能耗有多大影响?答:在围护结构中,门窗的朝向、面积和遮阳状况,对空调降温能耗和影响很大。研究结果表明:当窗墙面积比为30%时,东西向房间的设计日冷负荷及运行负荷,分别比南向房间的要大37%~56%及24%~26%,随着窗墙面积比的增大,东西向房间设计日冷负荷及运行负荷增加的幅度比南北向的要大得多。例如,当窗墙面积比增加10%时,西向房间的设计
Q: How much impact do doors and windows have on energy consumption of cooling in air conditioners? A: In the enclosure structure, the orientation, area and shade status of doors and windows have a great impact on energy consumption and cooling of air conditioners. The results show that when the window wall area ratio is 30%, the design daily cooling load and the operating load of the east-west room are respectively 37% -56% and 24% -26% larger than those of the south room. As the window wall As the area ratio increases, the day-to-day room cooling load and operating load increase more greatly than the north-south direction. For example, when the window wall area ratio increased by 10%, the design of the room to the west
