Experimental studies on air diffusion of a linear diffuser and associated thermal comfort indices in an air-conditioned space

摘要

Indoor air flow induced by a linear diffuser in an air-conditioned environmental chamber was studied experimentally. Macroscopic numbers describing indoor air flow such as the Archimedes number, the Reynolds number and the jet number were measured. Evaluation of the thermal comfort using the air diffusion performance index (ADPI) and the percentage dissatisfied (PD) was made. Comparison between those indices and the macroscopic numbers for the air flow are discussed.
