This study describes an experiment on a Task Unit and reports the results. The Task Unit coolsthe upper half of the body by isothermal air flow and warms the lower half of the body by a radiant panel. Tests were designed to compare heat removal by moving air after identifying the metabolic rate and how the thermal sensation and comfort sensation improve during the summer season. As a result, when the room temperature rises, the activity ratio of the Task Unit rises, too. Regardless of metabolic rate, subjects thermal sensation and comfortable sensation changes to "neutral" and "comfortable" after using the Task Unit for 5 minutes. Some subjects felt discomfort when exposed to the air current for a long time.
