甘肃河西地区太阳能与沼气互补供暖系统研究

Study on Solar Energy & Biogas Complementary Heating System in Hexi Region of Gansu Province

以甘肃河西地区典型农宅为例,结合当地丰富的太阳能资源和完善的农业产业化体系,建立了以太阳能和沼气互补的低温热水地板辐射供暖系统.针对太阳能应用的间歇性,提出了以沼气作为辅助热源,以应对极端恶劣天气下用户供暖的可靠性问题.该系统的适用性分析表明,太阳能与沼气作为互补热源可较好地解决该地区全天候供暖的问题,具有良好的经济性和环境效益,是改善当地人居环境的有效途径,有一定的应用推广价值.

Taking a typical farm-house in the Hexi region of Gansu province as an example,a solar-biogas as a heat source of low-temperature hot water radiant floor heating system is established based on the solar energy resource and perfect agricultural engineering system.It has been proposed to install auxiliary heat source biogas energy on the system for intermittent solar energy to the heating problems of the users in extremely bad weather,and its applicability is analyzed.The results show that solar-biogas heating system can solve the all-weather heating problem.The new system is an effective way to improve human settlements with good economic and environmental benefits,and has the good application promotion value.
