济南酒店排烟罩排风量计算依据

各家厨房差别较大,厨房面积与厨具、炉灶的数量不成正比,同样灶的产生的污染物和热量也差别很大。实际上厨房通风并非是全面通风,按换气次数设计风量会有很大的误差。

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.

实际上饮食业的实际情况要复杂:炉灶大小,炉灶有广式、苏式等分别;除了灶头外还有汤锅、煲仔、蒸锅烤箱等;在功能上,有烹调间,蒸煮间,面点间,烧烤间,西餐加工间,洗碗间等,散热量及污染物散发量都不同,简单按灶头数量确定排风量是不适当的。

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.厨房排风应避免大量的空调空间内的空气被抽排。需要通过自然补风和机械补风避免之。无论是自然补风还是机械补风都要考虑新风通过的路径,避免死区,以利于室内污染空气的抽排。机械补风要通过风管和送风口进行,管路系统不可复杂,同时避免局部风速过大。新风补充量以排风量的70%-80%为宜。

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%.

因厨房换气量较大,厨房内设置空调没有效果。通过抽取前厅少量的空调空气以喷口的形式直接使厨师处于风浴中,可以改善厨房内夏季高温、炉灶的烘烤给厨师造成的恶劣工作环境。

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.
