Abstract

This research investigates the effects of the physical properties of air ducts and air supply conditions on 60% RH humidity distribution and human comfort in air-conditioned research laboratories. The study uses computational fluid dynamics in combination with the Taguchi experimental design to analyse the data. For the supply air, 25 fabric air ducts were used. The simulation results show the isometric flow trajectories of the relative humidity distribution in the room and the contours of the ankle and neck planes of a male Thai subject with a humidity distribution between 50% and 55% RH. By focusing on the ankle and neck plane, researchers understand how moisture control can be optimized to enhance comfort and performance.
