Résumé

The objective of the present paper is to investigate the indoor environmental characteristics of an office building with an underfloor air-conditioning system. Thermal conditions in the room were monitored, including horizontal and vertical temperature distributions, supply and exhaust air temperatures, and globe temperature. Indoor air quality was investigated by measuring carbon monoxide, carbon dioxide and airborne particulate levels. Velocity distributions around a floor air terminal, and thermal comfort around a supply air terminal were also investigated. Room ventilation characteristics were obtained by a pulsed tracer gas technique. It shows that the underfloor air-conditioning system provides good ventilation characteristics in cooling modes, while airborne particulate levels are comparable with those found in conventional ceiling supply systems.
