建筑围护结构传热得热量计算方法的比较
Comparison of calculation methods for heat gain by heat transfer of building envelopes
摘要：
比较了围护结构传热得热量的两种计算方法：周期性反应系数法和传递函数法。与传递函数法相比，周期性反应系数法简化了计算，而且周期性反应系数能反映围护结构对周期性扰量的热响应，可作为评价围护结构热稳定性的指标。推导了传递函数系数与周期性反应系数间的关系式，可根据ASHRAE的数据库RP-626建立典型围护结构周期性反应系数的数据库，从而减少周期性反应系数法的计算量。
Abstract：
Compares the periodic response factor method and the transfer function method. Compared with the transfer function factor method, the periodic response factor method simplifies the calculation procedure, and the periodic response factor can reflect thermal response of building envelopes to a periodic pulse and be taken as thermal stability indicator of building envelopes. Deduces the relation expression between the transfer function factor and the periodic response factor, by which a data base of the periodic response factor for typical building envelopes based on the existed data base RP-626 of ASHRAE can be built so as to simplify calculation by the periodic response factor method.
