Description

Diffuser filter device for ventilation port {FILTER DEVICE OF DIFFUSER FOR AIR CONDITIONER}

The present invention relates to a diffuser filter device for ventilation.

In general, a duct and a diffuser are installed on the ceiling or wall of a building as an air conditioning system for controlling the amount of air supplied for cooling or heating or for controlling the ventilation of the room.

In particular, high buildings such as department stores and offices have noise and safety problems, so the windows on the outer walls are often formed in a closed manner, and even if the windows are made, they are made to be very small, so fresh air from outside is circulated into the interior. A separate duct system is required for ventilation control, such as sending out turbid indoor air to the outside, and a duct and a diffuser are indispensably installed for air conditioning systems for cooling and heating in summer and winter.

In general, ducts are installed in each room on each floor of a building by dividing into a main duct in the ceiling or wall and branched ducts that are divided into several branches, and a diffuser is installed on the ceiling or wall of each room so as to be connected to the branch ducts. , It is installed in a structure in which air supplied through the main duct is evenly distributed and supplied through a diffuser.

In general, a diffuser is installed such that a round damper blade is raised and lowered by a screw on the front surface of the air diffusion unit. The air is diffused and supplied while spreading radially by the blades.

At this time, the air supplied through the diffuser passes through the main duct and the branch duct, and is discharged in a state in which dust and foreign substances are contained in the air. Therefore, many people inhale air containing fine dust, which can cause health problems.
