摘要
农村清洁取暖是提高环保水平、促进能源结构调整、解决冬季取暖问题及创造就业机会等多重原因的综合考虑。以山西省某典型农宅为例,在考虑建筑围护结构节能改造及用户行为节能的因素下,对生物质采暖、电采暖、太阳能采暖等几种分散式供热技术进行了全寿命周期的经济性对比分析。结果表明,在确保炉具及生物质颗粒的来源和质量安全可靠条件下,生物质炊暖炉经济性最优;空气源热泵热风机兼具使用灵活和节能高效的特点,适宜在农村电网基础条件好或具备电网改造条件的地区推广。
Rural clean heating is a comprehensive consideration of multiple factors such as improving environmental protection,promoting energy structure adjustment,solving winter heating problems,and creating employment opportunities.This article takes a typical rural house in Shanxi Province as an example,and considers building energy-saving transformation and user behavior energy-saving factors to conduct a full life cycle economic comparison analysis of several distributed heating technologies such as biomass heating,electric heating,and solar heating.The results show that the economic efficiency of biomass heating technology is the best.And the air-to-air heat pumps(AAHPs)has the characteristics of flexible use and high energy efficiency,which is suitable for promotion in rural areas with good electric grid or electric grid capacity expansion.
