Numerical studies of airflows induced by mechanical ventilation and air-conditioning (MVAC) systems

摘要

Indoor air flows induced by mechanical ventilation and air-conditioning (MVAC) systems are simulated by the technique of computational fluid dynamics (CFD). Examples are taken to illustrate the capability of the technique. These include the evaluation of basic ventilation system designs, ventilation systems in an enclosed car-park, spot cooling system, air-con- ditioning system with chilled ceilling, cold air distribution system, effect of casual heat gain on the air diffuser induced air flow and the underfloor air supply system.
