沈阳市农村地区清洁取暖改造需求分析
Analysis of clean heating renovation demand in rural areas of Shenyang
摘要：
近年来,随着清洁取暖试点城市的深入推进,北方农村散煤替代工作取得显著进展。针对沈阳农村地区清洁取暖改造需求,开展了农村供暖现状调研,并监测了实际供暖效果,通过构建典型农房模型,计算分析了供暖负荷。通过分析沈阳地区供暖季室外温度特点,进行了空气源热泵结霜分析。归纳总结了沈阳农村地区清洁取暖需求,为科学开展农村清洁取暖改造提供准确依据和技术指导。沈阳农村地区清洁取暖设备应确保在-25 ℃时能正常工作,设备选型参考热负荷为132.85 W/m2,农户每个供暖季运行费用尽量不高于2 000元。
Abstract：
In recent years, with the in-depth promotion of clean heating pilot cities, significant progress has been made in the substitution of scattered coal in rural areas in northern China. In view of the clean heating renovation demand in rural areas of Shenyang, a survey on the current situation of rural heating is carried out, the actual heating effect is monitored, and the heating load is calculated and analysed by constructing a typical rural house model. By analysing the characteristics of outdoor temperature in the heating season in Shenyang, the frosting analysis of the air-source heat pump is carried out. This paper summarizes the clean heating demand in rural areas of Shenyang, and provides the accurate basis and technical guidance for the scientific renovation of rural clean heating. The clean heating equipment in rural areas of Shenyang should ensure that it can work normally at -25 ℃, the reference heating load of equipment selection is 132.85 W/m2, and the operating cost of each household in every heating season should not be higher than 2 000 yuan.
