摘要
本文根据山东地区农房取暖现状的特点,提出热源端清洁化改造(空气源热泵取暖系统、碳晶板取暖系统、燃气壁挂炉取暖系统)、用户端建筑能效提升(外墙保温、门窗更换、屋顶保温、增设太阳房连廊)的冬季清洁取暖方案,并计算获得农房节能改造后热指标约41.3W/m^2。最后从设备造价、运行费用两方面对方案进行了经济分析,获得农房建筑在节能改造的前提下,空气源热泵取暖方式的经济性最优。
According to the characteristics of rural heating in Shandong area,a clean heating scheme in winter is proposed for the transformation of heat source end (air source heat pump heating system, carbon crystal board heating system,gas wall hanging furnace heating system) and the improvement of energy efficiency of user end buildings (exterior wall insulation, door and window replacement, roof insulation,adding solar corridor). The thermal index of rural house after energy saving transformation is calculated to be about 41.3W/m^2. Finally, the economic analysis is made from the two aspects of equipment cost and operation cost. Under the premise of energy saving reconstruction, the air source heat pump heating system has the best economic performance.
