The temperature of inhaled air is of great significance to the design of air conditioning air supply parameters in the respiratory zone.This study was conducted in natural environment as well as air conditioning environment in the summer,in which eight students and eight elderly people were involved,and the subjects evaluated the comfort of inhaled air ranged from 18℃ to 34℃.The result show that the evaluation of inhaled air is better in natural environment than in the air conditioning environment,and the neutral temperature are 28℃ and 26℃ respectively.There is no significant difference in the thermal sensation of inhalation of air temperature in old age and young people,but the thermal valence,freshness and air quality of the old age are better than that of young people.And when inhaled air temperature is 2℃ higher than neutral temperature,the subjects symptoms improved obviously,therefore,the comfort of heating in winter deserves further study.
