Coal-fired heating in rural areas of northern China has led to a significant increase in pollutant emissions in winter, and clean heating can effectively promote the sustainable low-carbon development of rural areas in northern China. In this paper, the rural residential buildings in Shenyang in the cold region were selected as the research object. By the questionnaire research and site investigation, the heating status and heating effect of the existing rural residential buildings were analyzed. Through the four types of clean heating technologies: gas wall-hung boilers, low ambient temperature air source heat pump hot air fan, low-temperature air-source heat pumps water heaters and photovoltaic and auxiliary heat sources, and the heating effect after heat source transformation was summarized. Among the four clean heating schemes, the gas wall-hung boilers had the best heating effect, with an average indoor temperature of up to 19.0 ℃.

摘要

Coal-fired heating in rural areas of northern China has led to a significant increase in pollutant emissions in winter, and clean heating can effectively promote the sustainable low-carbon development of rural areas in northern China. In this paper, the rural residential buildings in Shenyang in the cold region were selected as the research object. By the questionnaire research and site investigation, the heating status and heating effect of the existing rural residential buildings were analyzed. Through the four types of clean heating technologies: gas wall-hung boilers, low ambient temperature air source heat pump hot air fan, low-temperature air-source heat pumps water heaters and photovoltaic and auxiliary heat sources, and the heating effect after heat source transformation was summarized. Among the four clean heating schemes, the gas wall-hung boilers had the best heating effect, with an average indoor temperature of up to 19.0 ℃.
