建筑室内热环境舒适区间确定方法

Determination Method of Comfortable Zone for Indoor Thermal Environment

科学合理的建筑室内热环境舒适区间的确定,对于提高室内人员舒适度,降低建筑能耗具有重要意义。本文介绍了用于确定室内热环境舒适区间的方法,包括经典的PMV方法,以及线性回归和Logistic回归2种基于实测数据的方法。然后,基于中国热舒适数据库对于各种方法的预测精度进行了对比和分析,结果发现Logistic回归方法对于满意率有较好的预测效果。进而使用Logistic回归方法计算得到了室内热环境舒适区间,发现不同气候区、不同季节和不同建筑类型下人体对热环境的需求存在一定的差异,指出应根据不同情况确定室内热环境参数。本文可为室内热环境精细化、多样化的设计以及暖通空调室内设计计算参数的确定提供参考。

The scientific and reasonable indoor thermal comfortable zone design is of great significance for improving thermal comfort and reducing building energy consumption.This paper introduced several methods to determine the comfortable zone for indoor thermal environment,including the classic PMV method and the linear regression and logistic regression methods based on actual data.The Chinese Thermal Comfort Database was used to compare the prediction accuracy of different methods.It is found that the logistic regression method has a higher accuracy in predicting the percentage of thermal satisfied.Logistic regression method was then used to derive the comfort zone,and found that there are certain differences in human demands for the thermal environment in different climate zones,seasons,and building types,suggesting that the thermal environment parameters should be determined according to different conditions.This paper can provide references for the refined and diversified design of the indoor thermal environment and the determination of calculation parameters for HVAC buildings.
