The difference between the number of larger kitchen, kitchen area and kitchen, stove is not directly proportionalto, the same pollutants and heat generation range also the difference is very big. In fact, kitchen ventilation isnot full ventilation, ventilation frequency design according to the air flow will have great error.
The actual situation actually catering to complex: the size of a stove, wide type, Su type stove burner andrespectively; in addition, pot soup pot, steamer oven; in the function, there are cooking, cooking, pastry,barbecue, Western-style food processing room, washing room, heat and pollutant emissions are different, according todetermine the number of simple stove exhaust volume is not appropriate.
3 kitchen exhaust should avoid air conditioning space within a large air is pumping. Need through the naturalventilation and mechanical make-up air to avoid. Both the natural ventilation or the mechanical ventilation shouldconsider the path through the fresh air to avoid dead zones, in order to indoor air pollution drainage. Themechanical ventilation through the wind pipe and outlet, piping system can't be complex, while avoiding the localwind speed is too high. Supply of fresh air to exhaust air volume is suitable for the 70%-80%.
Because kitchen ventilation volume is larger, the kitchen is arranged in the air conditioning had no effect. Througha small amount of air conditioning air extraction lobby to spout form directly make cook wind in the bath, canimprove the high temperature in summer, the stove in the kitchen to cook baked caused by bad working environment.
