三江源地区超低能耗农房节能降碳技术研究

Research on Energy Conservation and Carbon Reduction Technology of Ultra-low Energy Farmhouse in Sanjiangyuan Area

本文以青海省玛多县某一超低能耗示范农房为对象,采用TRNSYS软件对围护结构和用能设备系统开展仿真模拟研究。结果表明,采用高性能围护结构的农房可在高寒地区实现超低能耗目标;减碳技术措施方面,太阳能光伏供暖和太阳能光热供生活热水具有良好的减碳效果,空气源热泵由于高寒气候导致效率较低,在减碳方面并不具备明显优势;供暖、生活热水和照明等三项用能需求中,前两者具有较大的减碳改造潜力,特别是充分利用太阳能进行供暖和供生活热水。

Taking an ultra-low energy demonstration farmhouse in Maduo County,Qinghai Province as example,TRNSYS software is used to simulate the envelope structure and energy use equipment system.The results show that the goal of ultra-low energy consumption can be achieved in the alpine cold areas by using the high-performance envelope structure in farmhouses.In terms of carbon reduction technical measures,solar photovoltaic heating and solar heat for domestic hot water have good carbon reduction effects,while air source heat pumps do not have obvious advantages in carbon reduction due to low efficiency caused by alpine cold climate.Among the three energy needs of heating,domestic hot water and lighting,the first two have great potential for carbon reduction transformation,especially making full use of solar energy for heating and domestic hot water.
