摘要
分析了太阳能季节性地下水池蓄热供热系统的运行原理,建立了蓄热水池的数学模型,以哈尔滨一栋采用该供热模式的别墅建筑为实例,以满足太阳能保证率为目标、地下水池中水温为约束,通过改变集热器面积和地下水池的体积及其他相关参数,模拟计算得到太阳集热器面积和地下水池半径的最佳匹配、系统集热量与热损失量和水温与集热效率的关系。
The operation principle of a central solar heating system with seasonal thermal energy storage reservoir was analyzed, and the mathematic model of its thermal energy storage underground reservoir was developed. This was followed by a simulation investigation of a villa situated in Harbin, based on the local assurance factor of solar fraction and the temperature of the water in the reservoir. The relations between the solar collector area and the radius of the reservoir, and between the quantity of heat collected and lost in the system and the water temperature and the efficiency of the heat collection through changing the solar collector area and the volume of the underground reservoir were simulated and discussed. This may be helpful to design such a energy-saving and environmental friendly system.
