摘要
比较了房间空调逐时冷负荷的两种计算方法——Z-传递函数法和辐射时间序列法。与Z-传递函数法相比,在将得热量的辐射部分转化为逐时冷负荷时,辐射时间序列法无需迭代,计算简便,而且辐射时间因子能反应围护结构的热响应特性,可作为评价围护结构蓄热能力的指标。推导了房间传递函数系数与辐射时间因子的关系式,可通过现有的ASHRAE房间传递函数系数数据库计算典型房间的辐射时间因子。
Two methods for performing hourly room air-conditioning cooling load calculations are compared, that is the transfer function method （TFM） and the radiant time series method （RTSM）. Compared to the transfer function method, the radiant time series method needs no iteration and is convenient to convert radiant portions of heat gains to cooling loads. Besides, RTF can reflect the thermal response of building envelopes and be taken as the thermal storage capacity indicator. The relation between the weighting factors and RTF is deduced, by which RTF of typical rooms can be calculated on the basis of the existing ASHRAE database of weighting factors.
