摘要
提出了一种适用于被动式太阳能空气供暖的混凝土地板蓄热系统,并对该蓄热系统在寒冷地区农村住宅中的应用进行了热特性及其影响因素实验研究。讨论了该蓄热系统对室内热环境的作用,不同集热器朝向、热气流湿度及供风速度作用下地板蓄热系统的蓄放热特性。实验结果表明,太阳能空气集热耦合混凝土地板蓄热系统充分利用建筑本体结构蓄热,有效提高了太阳能供暖房间的室内温度及其稳定性。
In this paper, we proposed a concrete floor thermal storage system suitable for passive solar air heating, we proceed experimental study on the thermal characteristics and influencing factors of heat storage system for rural residential in the cold regions; discussed the indoor thermal environment impact of heat storage system; analyzed the store-release characteristics of floor thermal storage system with different collector orientation, different air humidity and different supply wind speed. Experimental result shows that, the concrete floor thermal storage system combined with solar air collector take full advantage of building mechanical structure thermal storage, and improve the indoor temperature and stability of solar heating house effectively.
