Indoor environment of house kitchens and adjacent living rooms is influenced by capture efficiency of an exhaust hood. When thermal plume over a cooking range is captured well by a hood, indoor environment can be kept in comfortable condition. However, in real house kitchens, there exists air disturbance due to air supply from ventilation system or air-conditioning system, and a part of thermal plume flows into a living room. Therefore ventilation system should be designed appropriately to keep capture efficiency of an exhaust hood high. In this paper, the relationship between position of air supply and indoor environment is studied by experiments and airflow visualization tests. Three typical air supplies at different position are supposed in the experiment and indoor environment is examined by the flow visualization and measurement of distributions of temperature and humidity. Secondly, the influence of air disturbance with cooking operations was examined by the experiments.
