摘要
大力推广清洁取暖是关系国计民生的重要工作,然而清洁取暖不是单纯的能源替代,特别在农村地区,同时需要考虑经济性和可推广性等。为此,提出了加装保温窗帘降低建筑整体热负荷,利用符合生活习惯的电热炕来满足局部热舒适需求,以及引入热泵热风机进行总体环境控制的策略。以山西农村某典型农宅为研究对象,利用TRNSYS对提出的清洁取暖方案进行模拟分析。结果表明,在取暖初期、室外温度最低时、取暖末期3个典型日均能够满足人体舒适性要求;在整个取暖期年运行费用可节约37.9%,费用年值没有显著的差异;同时SO_(2)、NO_(x)、PM_(2.5)和CO_(2)排放量分别降低了99.1%、92.1%、98.9%、89.4%。可为北方农村地区推广清洁取暖提供路线指导。
Promoting clean heating vigorously is an important task that concerns the national economy and people’s livelihood.However,clean heating is not just a simple substitution of energy,especially in rural areas,where economic and promotional factors need to be considered.Therefore,this study proposes strategies such as installing thermal insulation curtains to reduce the overall building heat load,using electric heated“kang”beds that meet local heat comfort needs and introducing heat pump heaters for overall environmental control.The study used a typical rural farmhouse in Shanxi as the object of simulation analysis using TRNSYS to evaluate the proposed clean heating solution.The results show that during three typical days of heating initiation,when outdoor temperatures are the lowest and at the end of the heating period,human comfort requirements can be met.During the entire heating period,the annual operating costs can be reduced by 37.9%,with no significant difference in annual cost values.Additionally,there are significant reductions in emissions,with decreases of 99.1%for SO_(2),92.1%for NO_(x),98.9%for PM_(2.5),and 89.4%for CO_(2).This study can provide a route guidance for promoting clean heating in northern rural areas.
