摘　　要：文章以PMV-PPD指标作为衡量室内热舒适的指标,以广州地区某办公建筑为例,分析了温度、相对湿度、空气流速对空调能耗的影响。研究表明:在相同人体热舒适条件下,相对湿度大、温度低的室内设计参数组合需要的空调能耗比相对湿度小、温度高的室内设计参数组合需要的空调能耗小。根据研究结果,文章提出了在相同人体热舒适条件下,室内设计参数选取的方法,可供工程设计人员参考。Utilizing the indoor thermal comfort index of PMV - PPD, this paper investigated the influence of tem perature, relative humidity and air velocity on the energy consumption of air conditioning by means of the software VE to simulate a developed air conditioning model of office building in Guangzhou. The simulated results showed that under a same indoor thermal comfort level, the required energy consumption of air conditioning for a combina tion of higher relative humidity and lower temperature was less than that for a combination of lower relative humidi ty and higher temperature. Based on the study results, a method which can be referenced by air - conditioning de signer was proposed for selecting the indoor design parameter combination under a same indoor thermal comfort lev el.
