Abstract
Subjective experiments with task conditioning system, RCU, were conducted to investigate the impact of different types of task-conditioning system on occupants with regard to their thermal comfort and productivity in a climate chamber. The subjects were indicated to perform the addition test. Also they were indicated to answer to the questionnaire relating to thermal sensation, comfort sensation, psychological and physiological responses, and the fatigue feeling both before and after the test. From the environmental measurements, it was checked that the ambient region and the task region were mostly controlled as the setting condition.
