Abstract

The comfort range of inhaled air temperature is meaningful to the design of air conditioning parameters at breathing zone. In summer, eight college students and eight middle-aged people were recruited to conduct a thermal comfort study in the natural and air-conditioning environment respectively. The subjects were exposed to different inhaled air temperatures from 18 °C to 34 °C at an interval of 2 °C. The study found that the perceived air quality and thermal pleasure of warm inhaled air is better in the surrounding of natural environment than that of air-conditioning environment. The neutral temperature of inhaled air is 28 °C and 26 °C, respectively. The thermal sensation vote has no significant difference between middle-aged and young people, while the thermal pleasure, air freshness and perceived air quality of middle-aged people are better than that of the young people. When the temperature of the inhaled air is 2 °C higher than the ambient temperature, the SBS symptoms are significantly increased. Therefore, the comfort range of temperature of heated air in winter is worth to be further studied.
