An experimental system was established for cross ventilation in a model room,it can be realized several cases under various opening configurations and different flow rates.The aim of the experiment was to examine the flow rates and pressure differences through every opening.And on this basis,according to the principle of building ventilation,the change laws of dis-charge coefficients of windward opening,leeward opening and the model room were analyzed.The result of the investigation will play a positive role in forecasting flow rate of buildings.
