Selection Of Ventilation Fan Fans And Classification Of Ventilation Fan

Weifang Jianliang Machinery Co.,Ltd | Updated: Jul 26, 2017

  Selection of Ventilation Fan fans and classification of Ventilation Fan

  Ventilation Fan fan this concept is great, as long as it is able to ventilate the Ventilation Fan can be called Ventilation Fan fans. Driven by the electric fan to drive the air flow, so that indoor and outdoor air exchange of a class of air-conditioning appliances. Also known as Ventilation Fan fan. The purpose of Ventilation Fan is to remove the indoor dirty air, adjust the temperature, humidity and sensory effects. Ventilation Fan Fans are widely used in homes and public places. The following in a different way, give it a simple description and classification.

  First, the classification of Ventilation Fan fans

  Ventilation Fan Fan fan into the exhaust port is divided into wall type (partition wall on both sides are free space, from one side of the wall to the other side of the Ventilation Fan), duct exhaust type (one side from the free space intake, And the other side through the duct exhaust), the catheter into the air type (one side through the duct into the air, while the other side of the free space exhaust), the whole catheter type (Ventilation Fan fan on both sides of the catheter placement, gas). (Air flows in the direction parallel to the axis of rotation, parallel to the direction of the shaft), and the axial flow Type (air entering and discharging are perpendicular to the direction of the shaft).

  Second, the Ventilation Fan fan Ventilation Fan

  Ventilation Fan Fan Ventilation Fan methods are exhausted, inhaled, and used three. Discharge from the natural air inlet into the air, through the Ventilation Fan fan to discharge dirty air; inhalation through the Ventilation Fan fan inhalation of fresh air, from the natural exhaust port discharge dirty air; and the use of the type of suction and exhaust are completed by the Ventilation Fan fan.

  The amount of Ventilation Fan and the number of Ventilation Fan needs to be different in different places. The amount of fresh air required for a person or per square meter is called the required Ventilation Fan. The number of times to replace fresh air within 1 hour is called the number of Ventilation Fan.

  The structure of the blinds is the most widely used Ventilation Fan fans, mainly by the motor, fan, wind box, panel, blinds and dedicated cable switches and other ancillary components. Motors generally use single-phase capacitor running asynchronous motor. 150mm specifications of the following Ventilation Fan fans also use shaded pole motor. Fan leaves generally use ABS, AS plastic injection molding, light weight and high strength. Wind box is usually made of thin steel plate stamping and spot welding, but also the use of plastic injection molding. Panel with plastic injection molding. Blinds are usually stamped with thin steel or tinplate. 200mm or more for the industrial Ventilation Fan fans, fan blades, wind boxes, panels are metal, used in factories, warehouses, office buildings, cafeteria kitchen, basement and other general environment exhaust Ventilation Fan, heatstroke use.

  The specifications of the Ventilation Fan Fan are divided into 100, 150, 200, 250, 300, 350, 400, 450 and 500 mm according to their fan diameter.
