As one kind of newly developed personalized ventilation (PV) system, relationship was explored between air movement perception/acceptability, preference/acceptability and perception/preference with tropical subjects, who had become passively acclimatized to hot conditions in the course of their day-to-day life. The tests were conducted in field environmental chamber (FEC) of National University of Singapore. 32 subjects (16 males and 16 females), performed normal office work, can choose to expose to four different PV airflow rates (4, 8, 12, 16 L/s) so as to simulating individual control. Ambient temperatures of 26°C and 23.5°C and PV air temperatures of 26°C, 23.5°C and 21°C were utilized to conduct parametric variation studies. Each combination was maintained for 15 minutes during which the subjects responded to computer-administered questionnaires. Under different PV airflow rates and ambient/PV temperature combinations, relationships between air movement perception/acceptability, preference/acceptability and perception/preference was analyzed.
