附加阳光房提升川西高原既有农宅太阳能利用潜力的研究
Study on additional sun houses to enhance solar energy utilization potential of existing residential rural buildings on Western Sichuan Plateau
摘要：
基于对甘孜和阿坝两州既有农宅建筑的调研和测试,分析了既有农宅的建筑布局特征和围护结构现状,模拟研究了附加阳光房及采取相应节能措施对农宅冬季温度的改善效果和节能效果。结果表明,通过附加阳光房及采取增设保温帘、敷设涂层、更换双层玻璃等节能措施可将川西高原农宅冬季典型日室内温度提升2～5 ℃,可减小约36.5%～57.2%的供暖负荷,太阳辐射利用率可达14%。
Abstract：
Based on the investigation and testing of existing residential rural buildings in Ganzi and Aba prefectures,this paper analyses the architectural layout characteristics and current situation of the envelope of the existing residential rural buildings,and simulates the effects of additional sun buildings and corresponding energy-saving measures on the winter temperature improvement and energy saving of the residential rural buildings.The results show that the typical daily indoor temperature of the residential rural buildings on the Western Sichuan Plateau in winter can be increased by 2 to 5 ℃ by additional sun houses and adopting energy-saving measures such as adding insulation curtains,laying coatings,and replacing double glazing,the heating load can be reduced by about 36.5% to 57.2%,and the solar radiation utilization rate can reach 14%.
