西安地区中小学校教室室内物理环境和学生热舒适研究

he physical classroom environment and the student thermal comfort are the important factors to influence the teaching quality. Firstly, by theoretical analyzing, the heat dissipating capacity and the moisture loss of teachers and students should become the factors of classroom energy-saving calculation, because the classroom is a densely populated place. Studies the Classroom Thermal Comfort comparatively of two primary and middle schools, in a synchronous way of the field measurement and questionnaire survey．The results show that Under natural ventilation condition, the suitable temperature limit could be increased to 25℃ in classroom in summer. In western China with dry climate (humidity <30%), when temperatures is above20℃， the thermal comfort in classroom could be improved by raising the relative humidity and enhancing natural ventilation.
