摘要
为降低盐城市快速增长的采暖及制冷能耗,以盐城市城镇分布最广的6层单元式住宅建立基本模型,通过模拟得出:盐城市居住建筑采暖需求远大于制冷需求,以此确定影响采暖和制冷能耗的空间设计改造方案和围护结构热工设计改造方案。首先讨论这些改造措施对采暖能耗的影响,然后优选出采暖节能效果较好的措施,讨论其对制冷能耗及总能耗的影响。EnergyPlus87软件模拟结果表明:南向阳光间的节能效果随阳光间进深的增大而下降,最多可节能662%。北向缓冲空间的节能效果随进深的增加而升高,可节能1344%。在北墙,屋顶增加聚苯乙烯泡沫保温层的节能效果最佳,南墙次之,东、西向则收效甚微。在北墙、屋顶、南墙增加40 mm厚聚苯乙烯泡沫保温板,分别可节能939%、1033%、424%。空间组织和围护结构改造后的节能模型较基础模型节能4407%。
In order to reduce the booming air-conditioning energy consumption in Yancheng,a basic model was established in Yancheng with the most widely distributed 6-story unit dwellings,and the space design elements and thermal design elements for the envelope that affected the energy consumption for heating and cooling were analyzed by EnergyPlus87.The simulation results showed that the energy saving effect of the southward sunlight room decreased with the increase of the depth of the sunlight room.The maximum energy-saving rate could be 662%.The energy saving effect of the northward buffer space increased with the increase of the depth,which could save energy by 1344%.It would be the best mothod for energy-saving to add EPS insulation boards outside north walls or roofs,the energy-saving effect would fall down if EPS boards would be installed outside sowth walls,and it would almost be useless to install EPS boards outside esat and west walls.Adding 40 mm thick EPS insulation boards to the north wall,roof and south wall could save energy by 939%,1033%and 424%respectively.The energy-saving model after the transformation of the space organization and the envelope structure was 4407%more energy efficient than the basic model.
