Numerical Simulation of Air Distribution and Experimental Research of Testing Room for Air Conditioning Unit

An experimental system for measuring the performance of air conditioning unit is designed and constructed according to standard JB/T9066-1999. Based on the k-¿ turbulence model, three dimension distribution of testing room is numerically simulated with the computational fluid dynamics technique. The air flow and heat transfer problems are resolved by finite volume method in interlacing grid with SIMPLE algorithm. The simulation results show that supply air parameters and the location of testing unit have an obvious effect on the air distribution. The experimental data and simulation results prove that the velocity and temperature of testing room distribute homogenously, and the indoor air environment meets the testing request of air conditioning unit.
