【Abstract】 By k ε turbulence model, the indoor air flow and solid heat transfer programs are resolved by finite element method, and the air distribution of the velocity and temperature fields in the chamber are numerically simulated. The effect of supply air velocity and supply air mode on airflow fields, and the effect of supply air temperature on temperature fields in the chamber are specially researched. It provides a basis for the optimized design of air distribution and comfortable study in the compartment with air conditioner.更多还原
