西北农村以煤炭为主的传统采暖方式能源利用率低、室内热舒适度差。为了利用丰富的太阳能满足西北农村单体建筑的热舒适度,以西北农村2座117 m2的单体建筑为研究对象,将一座单体建筑进行保温改造后,将其采暖方式先后改造成了太阳能驱动的强制循环散热器采暖和太阳能驱动的强制循环低温地板采暖,并在2个采暖季与传统煤炭燃烧驱动的自然循环散热器采暖相比较,试验研究了3种不同采暖方式的供能稳定性、室内舒适度和热经济性,研究结果表明:太阳能低温地板采暖效果最好,在环境最低气温?10℃时,室内平均温度能达到14℃,太阳能保证率为60.3%,二氧化碳减排量为6.22 t,静态投资回收期3.34 a,具有良好的经济环保效益。
Northwest China’s traditional coal-based heating methods have low energy efficiency and poor indoor thermal comfort. In order to make full use of abundant solar energy to meet the thermal comfort of single buildings in rural Northwest China, two single buildings of 117 m2 in rural areas of northwestern China are taken as research objects. After a single building is heat-insulated and transformed, its heating mode has been transformed into solar energy Driven forced circulation radiator heating and solar driven forced circulation low temperature floor heating. Compared with the traditional coal combustion driven natural circulation radiator heating in two heating seasons, the energy supply stability of three different heating methods was studied. Indoor comfort and thermal economy. The results show that the solar heating effect is the best, when the minimum temperature is 10 ℃, the average indoor temperature can reach 14 ℃, the guaranteed rate of solar energy is 60.3%, and the emission of carbon dioxide is 6.22 t, static investment recovery period 3.34 a, with good economic and environmental benefits.
