室内空气热舒适评价及空调系统控制模式探讨

Affecting of Indoor Air for Thermal Comfort and Applications of Air-conditioning System Control Modes

利用热舒适仪测试了温湿度等参数,分析了这些参数对人体热舒适指标PMV值的影响,研究结果表明室内空气温度是影响人体舒适性的最主要因素,相对湿度在60%时,温度每升高1℃,PMV值约增加0.3;室内温度在26℃时,相对湿度每升高10%,PMV值约增加0.1,相对湿度对人体舒适性的影响不容忽视。基于PMV的控制方法对于提高人们的舒适性和空调节能有重要意义。

After tested the room temperature and relative humidity by Thermal Comfort Data Logger, the difference of the factors on index of thermal comfort of people -PMV value were analyzed. The results show that room temperature is the main factor of effecting the thermal comfort of people. In relative humidity 60%, when room temperature rise 1 ℃, the PMV value increase 0.3 approximately; In 26℃ room temperature, when relative humidity increase 10%, the PMV value increase 0.1 approximately. Relative humidity has a little effect for thermal comfort of people. The control method of PMV is very important for improving people＇s thermal comfort and air-conditioning energy saving.
