空调房间舒适温度及热舒适性参数的计算研究

摘要

分析讨论了影响人体热舒适性的舒适温度以及热舒适性指标的定义及公式表达。热舒适性参数涉及预测平均热舒适度,自适应预测平均热舒适度,热感觉舒适度,热接受度等指标。空调房间舒适温度可采用平均室外温度简化计算,也可考虑室内温度的影响。热舒适性参数通常为室内温度以及中性温度的函数。当然,也可以考虑热感觉舒适度以及热接受度等与预测平均热舒适度之间的函数关系。分析结果表明,对于不同的建筑类型及气候区域,函数关系式中的系数取值不同。建立针对特定区域的室内温度及热舒适性标准具有极其重要的意义。%The definition and formulation of comfort temperature and thermal comfort parameters for human thermal accept-ability are discussed in this study.The thermal comfort parameters include predicted mean vote,adaptive predicted mean vote,thermal sensation vote,and thermal acceptability.The room comfort temperature can be simply calculated by the mean outdoor air temperature and/or indoor air temperature.The thermal comfort parameter is usually a function of indoor operative temperature and neutral temperature.Also,the relation between thermal comfort and thermal sensation vote or thermal acceptability can be applied.The results show that,for different building types or climatic regions,the coefficient assignments in the function are quite different.It is meaningful to explore an available formulation to express the indoor thermal comfort in a specific region or zone.
