Abstract
In this paper, the experimental research method was used to explore the effect of the temperature and the angle of the air supply on the indoor thermal comfort in the condition of stratum ventilation. The temperature range of air supply was 19~22 Celsius degrees and the air supply angle range was 30~150 degrees. When the supply air temperature was 19 degrees Celsius, the indoor PPD at different angles were large relatively and reached the maximal value when the angle of the air supply was 90 degrees. When the air supply temperature was 22Celsius degrees, the effect of air supply angle on the PPD value was less and reached minimal value when angle of the air supply was 45degrees. When the air supply angle was 90 degrees, the PPD value was more than 10% in different air supply temperatures which did not meet the requirement of indoor thermal comfort. The PPD value could meet the requirement in other conditions.
