摘　　要：本文基于传递函数法,对办公、公共饮食、宾馆饭店、医疗这4种典型公共建筑的空调负荷进行了模拟计算,分析了各类建筑的最不利负荷率与平均负荷率的关系。结果表明:不同功能建筑的最不利负荷率与平均负荷率的比值有所不同,最大值为1.325,最小值为1;单一建筑不同时间的最不利负荷率与平均负荷率的比值也有所不同,上午最大,在1.1～1.325之间变化,午后较小,小于1.1;若各类建筑的平均负荷率降低,其最不利负荷率会随之降低,且当负荷率降低时,变水温调节是适用的。In this paper,based on the transfer function method,the air-conditioning load of four typical public buildings were simulated,including offices,hotels,public canteens and hospitals,and the relationships between the most unfavorable load rate and the averaged load rate were analyzed.The results indicated that the ratios of the most unfavorable load rate to the averaged load rate would be different for different buildings,the maximum and minimum ratios were 1.325 and 1,respectively.Furthermore,the ratios for one kind of building would change with time,the values were maximum in the morning and changed between 1.1 and 1.325,and less than 1.1 in the afternoon.The most unfavorable load rate would reduce following the decreased trend of the averaged load rate,also the variable chilled water temperature adjustment technology was applicable when the load rate decreased.
