The location of the kitchen must be more than 20 meters away from the residential area. When the height of the building where the kitchen is located is less than 15 meters, the air outlet must be placed on the top of the building. If the height of the building where the kitchen is located is more than 15 meters and the kitchen is more than 15 meters, the height of the smoke exhaust outlet should be higher than the location of the kitchen.
The height of the gas collection hood from the ground should not be less than 1.9 meters and not more than 2.3 meters. If it is too low from the ground, the chef may encounter it. If it is too high, it is not conducive to the collection hood collecting oil fumes. The length and width of the gas collection hood should exceed 100mm of the equipment, which means that the gas collection hood should fully cover the equipment.
When designing the direction of the exhaust duct, it is important to avoid fire and air conditioning ducts. Once in conflict with them, installation in the later stages can be very troublesome. When designing, minimize the number of air duct bends and diameter changes as much as possible. When elbows occur, the angle should be within 90 degrees, and the exhaust effect of straight pipes is the best.
The air volume of the oil fume purifier is generally slightly larger than that of the smoke exhaust fan. As for the selection of corresponding oil fume purifier and smoke exhaust fan air volume, it can correspond to the parameter table of the manufacturer, and the formal and qualified manufacturers can refer to the table with similar differences.
When connecting the fan to the air duct, there should be no bends within the length range of twice the impeller diameter of the fan inlet and outlet. If there are bends, the inlet may cause abnormal performance of the fan, and the outlet may cause an increase in pipeline resistance, leading to a decrease in fan air output.
