摘要
减少对辅助热源的依赖是太阳能建筑设计的一个重要目标,利用建筑自身的集热蓄热能力,可以减少辅助热源量。研究了根据一维热网络模型、温控下辅助热源量的计算公式及热平衡方程,计算不同辅助热源的控制常数以及设定温度下室内温度和辅助热源量的变化;分析了不同的热源控制常数取值和设定温度对室内温度和辅助热源量的影响;讨论了设定温度对墙体蓄热利用的影响。
A good design of passive solar house is to reduce the auxiliary heat demand by utilizing heat gain and thermal storage capacity of building envelope. Basing on one-dimensional thermal circuit network model and auxiliary heat demand formula with temperature control method, the change of auxiliary heat demand and indoor air temperature under different auxiliary heat control constant and set-point temperature were determined, and the effect of set-point temperature on thermal storage of wall was also discussed. This study provides the basic theory of auxiliary heating system design for passive solar house.
