用度时数与反应系数评价围护结构隔热性能

Evaluation of the envelope heat insulation performance by using thermal comfort degree-hour and envelope response factor

引入了围护结构的"热稳定性度时数(DH)"和"反应系数(BER)"的概念,分析了不同形式的围护结构对室内空调冷负荷及室内空气热稳定性的影响.结果表明:用DH和EER可较全面地评价围护结构的隔热性能.

The influence of the building envelope on indoor thermal comfort and cooling load of air conditioning is presented by two introduced factors: thermal comfort degree-hour (DH) and building envelope response factor (BER). The developed result shows that the envelope heat insulation performance can be evaluated comprehensively by thermal comfort degree-hour (DH) and envelope response factor (BER).
