摘　　要：我国北方乡镇目前供暖的污染主要来自于“散烧”,是实现清洁供暖的较大障碍.该研究以吉林建筑科技学院的近零能耗建筑为研究对象,提出了一种特别适合于乡镇小建筑的新型清洁能源相变蓄热供暖方式.通过两个面积相同(60 m^(2))房间的对比实验,同时升温致两房间温度22℃时,相变房间的温度峰值高于普通房间0.4℃,且延后28 min到达峰值,停止升温后17 h仍可保持室内温度19.5℃.普通房间停止升温13.6 h室温即降至19.5℃.可见,加入相变材料能使室温保持更长的人体舒适温度,从而降低室温波动,减少建筑供暖能耗,为建筑供暖领域“双碳”目标的实现提供了一种全新的供暖模式.Pollution from current heating in China’s northern townships mainly comes from"decentralized combustion".It's the greater obstacle to clean heating in this way.This study takes the near-zero energy building of Jilin College of Architecture and Technology as the research object,and proposes a new clean energy phase change thermal storage heating method especially suitable for small buildings in townships.The experiment compares two rooms of the same size.The peak temperature of the PCM room was 0.4℃higher than that of the concrete room when the temperature of the two rooms was 22℃,and the peak temperature is delayed for 28 minutes,and the indoor temperature can still be maintained at 19.5℃for 17 hours after stopping the heating.The room temperature of an ordinary room stops heating up for 13.6 hours and drops to 19.5℃.The addition of PCM keeps the room temperature at a comfortable human temperature for longer.The addition of PCM can reduce room temperature fluctuations and reduce energy consumption for building heating.It provides a new heating model to achieve the"carbon neutral and carbon peak"goal in the building heating sector.
