摘　　要：对陕西关中乡村典型建筑室内热环境进行调研和实地测试,发现当地建筑平面布局较为单一,围护结构构造简单,冬季室内热环境质量较差,提出合理划分建筑平面、设计节能窗、完善墙体构造和设置屋顶保温系统等被动式太阳能采暖设计策略。利用DesignBuilder软件模拟分析了上述几种因素对室内温度与建筑能耗的影响。结果表明,合理划分室内空间可使南向房间日均温度提升约0.3℃;搭配塑钢中空玻璃窗可有效降低建筑采暖能耗,当南、北向窗墙比分别设为0.40、0.20时,可使建筑采暖负荷最小;采用煤矸石多孔砖替代实心粘土砖并采用外保温技术,可使南向房间日均温度提升约1.6℃,同时使建筑能耗降低17.56%;采用EPS保温屋顶时,EPS的厚度宜设置在70~100 mm。The indoor thermal environment of typical rural buildings in Guanzhong Area of Shaanxi Province is investigated and tested.It is found that the layout of local buildings is relatively single,the enclosure structure is simple,and the quality of indoor thermal environment in winter is poor.The passive solar heating design strategy is proposed,such as dividing the building plane reasonably,designing the energy-saving window,perfecting the wall structure and setting up the roof insulation system.DesignBuilder software is applied to simulate and analyze the influence of the above these factors on indoor temperature and building energy consumption.The results show that the reasonable division of indoor space can increase the average daily temperature of southbound rooms by about 0.3 ℃.With plastic steel hollow glass window can effectively reduce building heating energy consumption.The building heating load can be minimized when the ratio of south and north window wall is 0.40 and 0.20.The average daily temperature of southbound rooms can be increased by about 1.6 ℃ and the building energy consumption can be reduced by 17.56% by using coal gangue porous brick instead of solid clay brick and using external insulation technology.The thickness of EPS should be set at 70~100 mm when setting up the EPS insulation roof.
