1. Roof exhaust fan shall be set preferentially if heat or steam exhaust is required. 2. When heating, cooling or fresh air supply is required, warm air or cold air flow should be allowed to flow through the position of the staff as much as possible, so pipe fans or side wall fans are often used. 3. For fire fighting and smoke exhaust, roof fans or hoisted air ducts shall be preferred, so pipe fans are often used. Note: Make full use of natural wind and air flow (fan position and form shall be reasonably set). Fan selection in specific occasions 1. Warehouse ventilation (1) To check whether the goods in storage are flammable and explosive, such as paint warehouse, explosion-proof fans must be selected. (2) Depending on the noise requirements, roof fans or environment-friendly centrifugal fans can be selected. (3) The most conventional fan or exhaust fan can be selected according to the air exchange volume required by the warehouse. picture 2. Kitchen ventilation (1) For kitchens that directly discharge lampblack indoors (that is, the air outlet is on the indoor wall), fans or exhaust fans can be selected according to the size of lampblack. (2) For kitchens with large lampblack, lampblack needs to pass through long pipes, and there is bending treatment in the pipes, it is strongly recommended to use centrifugal fans (4-72 centrifugal fans are the most common, and 11-62 low-noise and environment-friendly centrifugal fans are also very practical). This is because the pressure of centrifugal fans is higher than that of axial flow fans, and lampblack does not pass through the motor, so it is easier to maintain and replace the motor. (3) It is suggested that the kitchen with strong lampblack should use the above two schemes together for better effect.
