Calculation of air volume of kitchen exhaust fan
How to determine the air volume of kitchen exhaust fans: number of ventilation fans = room volume x required air changes per hour (n)? Divide the displacement of the ventilator by X60. In other words, if your 20-square kitchen is 2 meters high, its volume is 40 cubic meters. 8 inches to 10 inch fan air volume is generally 120~200/ hour.
Characteristics of kitchen exhaust fan
The invention has the advantages of low price, large air volume, fast air exchange speed, low noise, low energy consumption, stable operation and high efficiency. The blades in the kitchen exhaust fan can also play a dustproof and waterproof role. The kitchen exhaust fan is not only used, but also elegant in appearance design, environmental protection and energy saving, which is the best choice for kitchen ventilation.
Installation method of kitchen exhaust fan
Install the kitchen exhaust fan first? Choose a good location, and then make sure the installation is smooth. The kitchen exhaust fan should be installed within 2.5-3 meters away from the air outlet without big obstacles, and it is best to install it more than 5 meters away from the roof. In addition, the bracket of kitchen exhaust fan must be kept horizontal and stable, and angle iron can also be installed next to it for fixing.
Ventilation principle of kitchen exhaust fan
When the kitchen exhaust fan exhausts air, the air pressure in the kitchen will drop, and the air in the kitchen will become thin, forming a negative pressure area. Due to pressure difference compensation, outside air will flow into the room. This is the principle of air pressure in physics. Some kitchen exhaust fans also have the function of cooling, and the principle of cooling is the principle of temperature leveling.
Precautions for kitchen exhaust fan:
1. Before installing the kitchen exhaust fan: Before installing the fan, carefully check whether the fan is intact, whether the fasteners and bolts are loose or fall off, and whether the impeller collides with the range hood. Carefully check whether the fan blades or shutters are deformed or damaged during transportation; When installing and selecting the air outlet environment, it should be noted that there should be no too big obstacles within 2.5-3m opposite the air outlet.
2. When installing the kitchen exhaust fan: the installation is smooth: when installing the fan, pay attention to the horizontal position of the fan and adjust it to the level and stability of the fan and the foundation plane. After installation, the motor shall not tilt; When installing the fan, the adjusting bolt of the motor should be in a convenient position to adjust the belt tightness when using; When installing the fan bracket, make sure that the bracket is horizontal and stable with the foundation plane. If necessary, install angle iron next to the fan for reinforcement. After the fan is installed, check the sealing around it. If there is any gap, it can be sealed with sunlight board or glass glue.
Today, Bian Xiao introduces the calculation of air volume of so many exhaust fans. I believe everyone has a certain understanding of the calculation of exhaust fan air volume. When choosing, you might as well consider these methods introduced by Bian Xiao. In fact, the kitchen exhaust fan plays a great role, which can help us to remove oil fume, keep the family clean and tidy, and let us have a clean and beautiful kitchen environment. Through the above detailed introduction, I believe everyone is familiar with the calculation of exhaust fan air volume, and I hope my introduction can help readers.
