Simulations of Task-Ambient Air-Conditioning Systems by Computational Fluid Dynamics, Refrigerating-Cycle Simulator, and Pedestrian-Behavior Model

چکیده
The effects of task-ambient (TA) air-conditioning systems on the air-conditioning loads in small and large spaces and the thermal comfort of occupants were studied using computational fluid dynamics (CFD), pedestrian-behavior model, and refrigerating-cycle simulator. Task areas were set up to match with crowdedness as predicted by the pedestrian-behavior simulations. Subsequently, a variety of TA air-conditioning systems were designed to selectively control the microclimate of the task areas. Their effects on the thermal environment in the objective spaces in winter were predicted by CFD. The results were evaluated in relation to the thermal comfort of occupants and the air-conditioning loads. The results of simulations showed that adequate arrangements of TA airconditioning systems improved thermal comfort and decreased air-conditioning loads simultaneously.
