摘　　要：提出了一个合理选择同时发生的太阳辐射、干球温度和湿球温度的统计方法。该方法基于热传递的基本原理,将三个气象参数与建筑特征组成一个单一的被称为等效温度的影响因子,确保三个同时发生的气象参数的联合概率能满足所要求的空调系统的容量可靠性水平。将该方法应用于香港的气象数据得出同时发生的设计气象参数,与传统方法得到的气象参数进行了对比,结果表明,传统方法得到的参数在许多情况下可能被显著地高估,新方法可以直接确定峰值冷负荷,简化设计冷负荷的计算。Presents a statistic method for rationally selecting coincident solar irradiation, dry bulb and wet bulb temperatures. The method combines the three weather parameters and building characteristics into a single impact factor equivalent temperature--based on the principle of heat transfer, ensuring that the joint probability of occurrence of the three parameters can match the capacity reliability level of air conditioning systems. Applies the method to weather data of Hong Kong to generate the coincident design weather parameters and compares them with those data obtained by conventional method. The results indicate that the latter data may be significantly overestimated in some conditions, and that the new method can calculate peak cooling load directly and simplifies design cooling load calculation.
