人体舒适度与室内热环境

Thermol Comfort and Indoor Environments

通过对自然通风环境、实际空调环境、实验空调环境与人体舒适度的关系的分析,发现在自然通风条件下人体热感觉随着温度变化是最小的,仅为0.0949(TSV)/℃,而在实际空调环境下,热感觉与温度关系最大,变化率为0.3245(TSV)/℃.说明在自然通风条件下,影响人体突然感觉的其他因素比实际空调环境以及实验空调环境的要多;本文对三种热环境下热不可接受率与实测不舒适度进行比较,发现实测不舒适度远高于热不可接受率,说明热感觉并不等同于热舒适;在自然通风环境下,高温高湿(28℃,80%以上)条件下,空气焓值大小对实测不舒适度的影响比温度、相对湿度更为明显.

By analyzing the human comfort under the natural ventilation environment,actual air-conditioned environment and experimental air-conditioned environment,it is revealed that under the conditions of natural ventilation,human thermal sensation is the smallest as the temperature changes,only 0.0949（TSV） / ℃,while in the actual air-conditioned environment,the relationship between thermal sensation and temperature change is closest at the rate of 0.3245（TSV） / ℃.Compared with the actual air-conditioned environment and experimental air-conditioned environment,there are more factors,which affect the human thermal sensation under the ratural ventilation conditions.In this paper,three kinds of thermal environment are compared.The results show that the actual thermal uncomfort is higher than the thermal unacceptable.In natural ventilation conditions with temperature and humidity（28 ℃,80%） the effects of air enthalpy value on the measured degree of discomfort are more obvious than the effects of temperature and relative humidity.
