Abstract
Measurements on thermal environment were conducted in university lecture rooms underair-conditioning for various set temperatures in summer and winter. Simultaneous measurements in nine rooms showed the different results in agreement of measured temperature with set temperature from room to room and from case to case. Full measurements in the smallest room showed poor attainment of set temperature at the abdomen level of a sedentary person and much poorer at the foot. The vertical temperature difference more than four degrees between head and foot of a sedentary person in heating was reduced to less than three degrees using an air circulator under development, resulting in meeting to ASHRAE Standard 55-2004.
