严寒地区农宅附加阳光间能耗及效益评价分析

Analysis on energy consumption and benefit evaluation of solar house of rural residences in severe cold areas

在我国严寒地区农村住宅外附加阳光间可以提高室内温度,减缓温度波动并减少采暖能耗。以安达市某农村住宅为例,基于EnergyPlus进行采暖期能耗模拟,并进行经济和环保效益的评价分析。结果表明:当采暖设计温度为18℃时农村住宅附加阳光间的节能效率最高,可达22.73%。室内采暖设计温度每升高2℃,总能耗呈1.4~2.7倍增长,采暖设计温度为20℃的采暖能耗为14℃的6.7倍。在经济效益方面,在寿命期15 a内均能收回成本,在环保方面,阳光间在寿命期内可以减少排放二氧化碳13.52 t、二氧化硫238.80 kg、氮氧化物205.20 kg及粉尘99.63 kg,同时节约碳排放税35272.0$,经济和环保效益非常显著。

Adding solar house to rural residences in the severe cold areas can increase indoor temperature,slow down temperature fluctuations and reduce heating consumption.Take a rural residence in Anda City as an example,based on EnergyPlus the energy consumption during the heating period is simulated,and the economic and environmental benefits are evaluated.The results show that when the heating design temperature is 18℃,the energy saving efficiency of rural residential additional solar house is reaching 22.73%.For every 2℃increase in indoor heating design temperature,the total energy consumption increases by 1.4 to 2.7 times,and energy consumption at the heating design temperature of 20℃is 6.7 times that of 14℃.In terms of economic benefits,the cost can be recovered within 15 years of life.In terms of environmental protection,the solar house can reduce emissions of 13.52 tons of carbon dioxide,238.80 kg of sulfur dioxide,205.20 kg of nitrogen oxides and 99.63 kg of dust during the lifetime,while saving carbon emissions,with tax 35,272.0 CHY,and the economic and environmental benefits are very significant.
