The countercurrent often occur at smoke protect opening on the pressure type smoke extraction system. This paper is reported the occurrence condition of countercurrent and the result used punched panel on supply opening to countercurrent measures. The measurement results are compared with the simulation results. The measurement results are similar to the simulation results except the airflow field upper smoke protect opening. In case of supply opening position at the middle of wall and the under of wall against the smoke protect opening, the countercurrent occur upper the smoke protect opening. The experiment used punched panel is not able to prevent the countercurrent. On the contrary, the simulation result shows the condition of non-countercurrent.
