摘要
通过对全年干球温度概率分布的双波简化模型中分布参数物理意义的分析,在考虑冬夏季方差不相等的条件下提出了确定分布参数的方法,建立了全年干球温度的截尾正态分布简化模型。该模型的应用更为方便和精确,可方便地用来估算暖通空调建筑物的能耗、计算度日数和温频,可供暖通空调系统的设计、运行作参考。
Based on the analysis on physical meaning of probability distribution parameters in simplified double-wave model for probability distribution of annual dry-bulb temperature, this paper creates the truncated normal distribu-tion model, and puts forward a new method of determining distribution parameters in the case of unequal standard errorin winter and summer temperature wave in order to utilize the model more correctly and conveniently. This model can beused in estimating energy consumption of HVAC system, calculating degree-days number and temperature frequency,and can serve as a reference to the design and operation of HVAC system.
