In the previous paper, the measured data of temperature distribution and energy consumption of a real kitchen was presented and the effectiveness of the displacement ventilation system with ceiling air supply openings was discussed. Even if the airflow rate was decreased in displacement ventilation system, the thermal environment was almost same as conventional system with lager airflow rate. This paper describes CFD simulation to demonstrate the airflow and temperature distributions in the real kitchen. The simulated results are similar to the measured one and further studies are conducted to examine the shape and position of ceiling exhaust openings. This paper also shows that estimated outdoor air cooling period for the displacement ventilation is much longer than for the conventional one.
