摘要(Abstract)：

为减少被动式超低能耗建筑的新风负荷对常规能源的消耗,同时,保持室内良好的空气品质,提出了一种太阳能集热系统与带热回收的新风系统相结合的方案。以西宁市为例,分析计算了该太阳能新风系统在不同集热器安装倾角、不同太阳能保证率下的集热器采光面积。结果表明在太阳能集热器的安装倾角为90°、对新风负荷的太阳能保证率为80%时每户住宅所需的集热器采光面积为4.7 m2,同时系统一年可节约能耗4 022.13 MJ,换算成电量约1 117.26 k W·h,表明该太阳能新风系统在被动式超低能耗建筑中的应用是经济可行的。
A combined system of solar collector and new air system with heat recovery is proposed to reduce the conventional energy consumption for fresh air heating load of passive low-energy buildings and maintain the indoor comfort. And taking Xining as an example, the collector aperture area about the solar energy system is analyzed and calculated in different installation angle of collector and different solar fraction.The results show that when the solar collector installation angle is 90°, the solar assurance rate is 80%, the required collector area of per household residence is 4.7 m2, and the system can save energy 4 022.13 MJ/a,converting into electricity is about 1 117.26 k W·h/a, which indicates that the solar fresh air system application in passive low-energy buildings is economically feasible.
