摘 要: 对长沙市非空调环境下的人体热舒适性进行了问卷调查,分析了长期生活在湖南的本地人与北方人对同一环境的冷热感和湿度感,发现本地人耐寒性与耐湿性更强。研究了空气比焓、温度、湿度等参数对热感觉平均投票值的影响规律,发现在低温区域相对湿度对人体舒适感有明显作用。统计了不同环境下相应的热感觉平均投票值、湿度感以及实际不满意率的对应关系,并与Fanger提出的PMV-PPD指标进行了对比。 Investigates the thermal sensation by questionnaires in Changsha, analyses the thermal sensation and humid sensation, and finds that natives have better cold endurance and humid endurance than northlanders. Discusses effects of thermal environment parameters such as specific enthalpy, temperature, relative humidity on the mean thermal sensation vote, and obtains that under low temperature the relative humidity has evident effect on thermal comfort. Analyses the relations between the mean thermal sensation vote, humid sensation and actual dissatisfied percentage, and compares the results with the PMV-PPD indexes by Professor Fanger.
