Exhaust air conditioning fan

Exhaust air conditioning fan

In general, air conditioning equipment and exhaust fans are designed and produced considering many criteria. In order to have a proper ventilation, you must make and use all the components of the air conditioning in the best possible way. These components include: suction ventilators (exhaust fan) and forward blower fans (positive pressure), air transfer channel network, heating heaters, silencers and filters.\r[http://nhttps://www.azintahvie.](http://nhttps://www.azintahvie.) com/Search/44/اگزاست-فن-ته? ?یه
Exhaust fan :
Centrifugal fan and axial fans can actually be called the heart of the ventilation system. And the air valves move in the desired direction. Fans in different sizes and shapes with unique abilities can be designed and produced. The main purpose of installing an exhaust fan is to remove hot air, moisture, unpleasant odors, dust and other pollutants.
Categories of exhaust fans
1- Centrifugal exhaust fan Utility Exhaust Fan
This category of fans can be used with two types of backward and forward propellers for air suction and blowing. This device consists of a working wheel that is connected to a special shaft, inlet and outlet pipe and spiral housing. Air (displaceable gas) is drawn several times and drawn from the rotating blades into the fan housing. Therefore, changing the direction of air flow (gas) from a parallel line directly to the axis becomes radial. Then, the centrifugal force pushes the air through a special opening in the chamber. Another name for this device is the spiral fan exhaust because of its spiral shape.
The rotation of the impeller in the spiral fan exhaust can be right-handed or left-handed. The number of blades affects the type and purpose of the device. There is one caveat: which way the blades themselves are positioned (front or back). In some cases, it is of fundamental importance. For example, a centrifugal fan equipped with curved back blades can save up to 20% in energy.
On the other hand, forward curved blades can reduce the diameter of the impeller they are attached to. and accordingly, the fan itself can be more compact. Another advantage: a little faster and the noise level is reduced.
Centrifugal fan exhaust can be used in forced extraction systems, kitchens, restaurants, laundries, metallurgical and chemical industries, oil refineries. In this case, note that if you intend to suck and discharge relatively clean, non-acidic air. It is enough to use carbon steel with a resistant paint coating for the propeller and snail parts. In cases where explosive gases are present, equipment with aluminum alloy or cast iron coating is used. And use anti-explosion engines for propeller rotation. At the same time, to move acidic air and corrosive gases, it is better to use plastic or stainless steel material to make the body and housing of the exhaust fan.
