多能源互补的农村绿色建筑试验研究
Experimental study on rural green buildings with multi-energy hybrid systems
摘要：
针对西北干旱、寒冷地区农村建筑体形系数大、保温性能差、供暖系统能耗高等问题，采取了加强围护结构保温，采用集热蓄热墙与附加阳光间相结合的被动式太阳房、太阳能集热器与生物质炉及地热盘管相结合的主动式供暖系统，采用地面保温蓄热系统、节能炕等多能源互补的系统等措施。结果表明：室内基础温度达到14 ℃以上；对于一个建筑面积121.2 m2的农村住宅来说，一个供暖季耗煤+秸秆的总量为3.75 t左右。
Abstract：
Aiming at the problems of high shape coefficient, poor thermal insulation performance and high energy consumption of heating systems in rural buildings in arid and cold areas of Northwest China, adopts some measures including strengthening the building envelope insulation, and adopting the passive solar house system combining with heat storage wall and additional sunlight rooms, the active heating system combining with solar collector, biomass furnace and geothermal coil, the underfloor thermal insulation and heat storage system, as well as the energy saving Kang and other energy hybrid systems. The results show that the basic indoor temperature reaches over 14 ℃, and the total consumption amount of coal and straw during a heating season is about 3.75 t for a rural residence of 121.2 m2.
