This work presents an improvement of the air change rate efficiency for a closed-system broiler house with Multi Inlet System (MIS). Computational Fluid Dynamic (CFD) was applied to calculate and estimate the air flow in the house, 14 × 120 × 2.5 m3, which was selected for the study. The broiler house was installed with nine MIS channels along the house length and two channels at the front of the house. Then the air velocity, temperature and air change rate were measured and compared with the result of CFD. From the air flow testing in the broiler house, MIS can increase 57% of area that the air change rate is in the standard criteria. The average velocity was increased 25% and the fluctuation of air velocity was decreased. Furthermore, it was found that the experimental results of air velocity were similar to that calculated from CFD. Hence, the results of CFD of the flow can be used to explain the other points of the air flow and applied to further improve the air condition control in the closed-system broiler house.
