CHANGE OF THERMAL COMFORT OF STUDENT BY INSTALLATION OF AIR-CONDITIONING SYSTEM IN A CLASSROOM

Abstract

The purpose of this study is to clarify the changes of thermal environment in a college classroom and to evaluate the improvement in thermal comfort of college students by installation of air-conditioning system in a classroom. The key findings from this study are as follows; 1) By the installation of air-conditioning, the classroom temperature fell within the Japanese school environmental sanitation guidelines in summer. 2) The students felt thermal neutrality and thermal comfort all the year round after air-conditioning was installed in the classroom. 3) If thermal environment in the classroom meets the boundaries of the comfort zone, the students will satisfy with the thermal environment. 4) Threshold of hot humid envrionment occurred at 27.1°C SET^* by probit regression analysis.
