川西藏区居住建筑可再生能源供暖热源适宜性研究

Suitability of renewable energy heating sources for residential buildings in Tibetan area of western Sichuan

通过分析川西藏区太阳能集热量与建筑供暖耗热量之间的平衡关系,以太阳能供暖保证率20%,50%,100%作为供暖能源划分依据,对川西藏区太阳能、空气源热泵与其他可再生能源供暖适宜区间进行了划分,得到4个区分别为Ⅰ区(太阳能系统)、Ⅱ区(空气源热泵辅助太阳能系统)、Ⅲ区(太阳能辅助空气源热泵系统)及Ⅳ区(其他可再生能源辅助空气源热泵系统),提出了居住建筑可再生能源供暖模式优选图谱。选择川西藏区的6个地区进行分析,在建筑与集热器面积比为3.0的条件下,根据建筑热指标和优选图谱得到6个地区的供暖能源形式及其适用条件。

By analysing the balance between solar heat collection and building heating consumption in the Tibetan area of western Sichuan,taking the solar heating guarantee rate of 20%,50%,100%as the basis for the division of heating energy,divides the appropriate heating range of solar energy,air-source heat pump and other renewable energy sources in Tibetan area of western Sichuan.Obtains four zones:zone I(solar system),zone II(air-source heat pump assisted solar system),zone III(solar-assisted air-source heat pump system),and zone IV(other renewable energy assisted air-source heat pump system),and proposes a choose-the-best diagram of the renewable energy heating mode for residential buildings.Analyses six selected regions in Tibetan area of western Sichuan.At the building to collector area ratio of 3.0,obtains the heating energy forms and applicable conditions of six regions according to the building heat index and the choose-the-best diagram.
