Abstract

In the rural areas of northwest China, winter poses severe challenges due to its harsh conditions and inadequate heating systems. The assessment of indoor environments in rural houses across three regions in Shaanxi Province reveals that the existing heating systems are inadequate to meet the thermal requirements of residents. A comprehensive examination was conducted on the climate and available resources within six selected cities in rural Shaanxi. Economic evaluations were performed using the levelized cost of heat (LCoH) method to compare suitable heating schemes for these cities. The results demonstrate that considering both price and reserves of natural gas and biomass, the biomass boiler (BB) and gas boiler (GB) heating system are preferred. In four cities located in central and southern Shaanxi, BB offers the most economical solution with a minimum LCoH at 0.0963 CNY/kWh. GB proves to be more cost-effective in two cities in northern Shaanxi. Additionally, it is recommended to consider implementing a solar-air source heat pump composite heating system (S-ASHP). The suggested solar fraction ranges from 9% −14% in central and southern Shaanxi, while reaching 27% in Yulin. These findings effectively inform decision-making regarding the selection of clean heating modes based on economic considerations in rural areas.

陕西农村住宅供暖系统的实地调查、测量与经济评价

在中国西北的农村地区，由于恶劣的条件和供暖系统的不足，冬天带来了严峻的挑战。对陕西省三个地区农村住宅室内环境的评估表明，现有的供暖系统不足以满足居民的热需求。对陕西农村6个城市的气候和可利用资源进行了综合考察。使用平均供热成本（LCoH）方法进行经济评价，比较这些城市的合适供暖方案。结果表明，综合考虑天然气和生物质的价格和储量，生物质锅炉（BB）和燃气锅炉（GB）供暖系统是首选。在陕西中南部的四个城市，BB提供了最经济的解决方案，最低LCoH为0.0963元/千瓦时。事实证明，在陕北的两个城市，GB的成本效益更高。另外，建议考虑采用太阳能-空气源热泵复合供暖系统（S-ASHP）。陕中、南部地区建议的日照比例为9% ~ 14%，榆林地区可达27%。这些发现有效地为农村地区基于经济考虑选择清洁供暖模式的决策提供了信息。
