【摘要】：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。
[Abstract]:The traditional heating mode of coal in northwest rural areas has low energy utilization and poor indoor thermal comfort. In order to use abundant solar energy to meet the thermal comfort of the single building in northwest rural areas. Taking two 117m2 single buildings in northwest rural area as the research object, one single building was transformed with heat preservation. The heating mode has been transformed into solar driven forced circulation radiator heating and solar energy driven forced circulation low temperature floor heating. Compared with the natural circulation radiator driven by traditional coal combustion in two heating seasons, the energy supply stability, indoor comfort and thermal economy of three different heating modes were studied. The results show that solar low temperature floor heating effect is the best in the environment minimum temperature? At 10 鈩，
