摘要:

根据太阳能资源分布和建筑气候条件将西北地区划分为7类典型区域,以各区域典型建筑为模型建筑,从能源支撑、经济特性、技术特性及环境效益等方面对燃煤锅炉、燃油锅炉、燃气壁挂炉、电锅炉、空气源热泵、生物质锅炉6种太阳能供暖辅助热源进行了综合分析,并对其进行了模糊定量处理。结果表明:生物质锅炉作为西北乡村地区太阳能供暖辅助热源适宜性优度最高,燃油锅炉、电锅炉优度最低;燃煤锅炉、生物质锅炉的适宜性优度随经济性权重的降低而降低,家庭收入较高的地区更倾向于选择空气源热泵、燃气壁挂炉等新型供暖形式。

Abstract:

The areas of Northwest China is divided into seven typical regions according to the distribution of solar energy resources and climate conditions. Taking the typical buildings in each region as model buildings, choosing the coal-fired boiler, oil-fired boiler, gas-fired boiler, electric boiler, air-source heat pump and biomass boiler as the representative auxiliary heat sources, performs a comprehensive analysis from the aspects of energy support, economical efficiency, technical characteristics and environment influence by using the fuzzy mathematic methods. The results show that the biomass boiler has the highest suitability as the auxiliary heat source of solar heating, and the oil-fired boiler and electric boiler get the lowest priority-degree. The priority-degrees of coal-fired boiler and biomass boiler decrease with the decrease of economic weight, and the areas with higher family income are more likely to choose the air-source heat pump, gas-fired boiler and other new heating modes.
