Résumé

Microenvironment of a typical office workplace consisting movable panel (MP) task conditioning systems was studied by numerical simulation. Numerical simulation by k-epsilon 3-D turbulent model was conducted to study the influence of supply velocity, air blowing distance and size of MP supply outlet on microenvironment of MP task conditioning system. Temperature and velocity distribution, draught rating and predicted percentage of dissatisfied of the room and workstation were studied. Results showed that room temperature was distributed by region, and occupant was exactly in supplying area. Temperature around occupant was apparently lower than surrounding temperature. Results also showed that task conditioning can provide excellent working environment when supply velocity, and size of supply outlet were well designed. To summarize, flexible control of task conditioning system can create a more comfortable indoor environment.
