Levels of Adaptation in Dry-hot and Dry-cold Climate Zone and Its Implications in Evaluation for Indoor Thermal Environment

摘要

To understand the characteristic of human adaptive thermal comfort in the districts with dry-hot and dry-cold climate type,approach of field survey of thermal comfort has been car ried out in Turfan of China.Statistical regression analysis has been used to find out the corre lation between human thermal sensation and the operative temperature in winter and summer,and adaptive coefficient(λ） proposed in adaptive PMV model (aPMV) has been used to ana lyze the levels of adaptation of people there.The adaptive coefficient（λ） is -0.48 for winter and 0.62 for summer.Theλ for summer varies from Evaluation Standardfor indoor therwial environment in civil buildings in China.This indicates that a special evaluation index of(λ) should be given for those districts with dry-hot climate type which is although in the same climate zone.
