EXPERIMENTAL STUDY OF AIRFLOW UTILIZATION FOR THERMAL COMFORT IMPROVEMENT IN SUMMER HOT-HUMID CONDITIONS

摘要

The use of airflow to improve summer hot-humid conditions is regarded as effective method from a standpoint of the saving energy.However, excessive addition of airflow contains danger to let thermal dissatisfaction rate increase. This paper consideration that made much of thermal comfort about adjustment of the summer environment by the use of airflow through an experiment. The following results were obtained. 1)Increase of airflow of 0.27m/s was demanded by every difference of air temperature 1 deg C from 24 degCin order to turn thermal sensation into neutral. 2)Even if gave suitable airflow, as room air temperature became high, thermal comfort improved took a low value. 3)The limit of Room air temperature that comfortable range was provided by assistance of airflow was 29deg C.
