Experimental and numerical investigation on cooling characteristics of partition air supply system

This paper evaluates the cooling performance of a personalized partition air supply system, a ceiling air supply system, and an underfloor air supply system using results obtained from full-scale chamber experiments and computational fluid dynamics simulations. The experimental and the simulation results indicate that the partition supply system provides better indoor thermal comfort levels than the ceiling supply system and the underfloor supply system. The partition supply system can reach the desired thermal comfort levels around the occupant faster than the other two systems. It can also reduce the cold draft affecting the occupant by adjusting the operable outlet grilles on the partition. The simulation results agree with the testing data for similar airflow and temperature distributions.
