Classification of exhaust fans

Classification of exhaust fans

Divided by intake and exhaust ports The exhaust fan is divided into partition type (both sides of the partition hole are free spaces, and air is exchanged from one side of the partition to the other), duct exhaust type (one side is intake from the free space, and the other side is exhaust through the duct), duct intake type (one side is intake through the duct, and the other side is exhaust to the free space), and full duct type (both sides of the exhaust fan are equipped with ducts, and air is intake and exhaust through the duct). According to the form of airflow, it is divided into centrifugal (air enters parallel to the axis of rotation and exits perpendicular to the axis), axial (air enters parallel to the axis of rotation and exits parallel to the axis), and cross flow (air enters and exits perpendicular to the axis).

The issue of indoor odor should not be underestimated

Little knowledge about home ventilation fans Although household ventilation fans have been widely used in cities, many people still do not understand some basic knowledge of ventilation fans. A ventilation fan is a type of air conditioning device that is driven by an electric motor to rotate the blades and drive the airflow, allowing for the exchange of indoor and outdoor air. It is also known as a ventilation fan. The purpose of ventilation is to remove indoor polluted air and regulate temperature and humidity effectively. Generally speaking, there are three types of ventilation methods for household ventilation fans: exhaust, suction, and combined. The exhaust type enters the air from the natural intake and expels polluted air through a ventilation fan; The suction type draws in fresh air through a ventilation fan and expels polluted air from the natural exhaust outlet; The combination of intake and exhaust is completed by a ventilation fan.
