Overview
As the air outlet or return air outlet of the air conditioning system, it can be used for the air outlet or return air system and can also be used as decoration, which is beautiful and elegant.
Two types

Double-layer louvered air inlets can be used directly with fan coil units or can also be used in central air conditioning systems. The end blade angle can be at r

~

A single-layer louvered air outlet is often used as a return air outlet, and a multi-leaf split regulating valve can also be installed behind it to control the air volume.
The side wall grille-type rainproof air vent blades are fixed and are often used for the return air of washrooms and toilets, and the decoration of elevator pipe openings and inspection openings.
The openable side wall grill door hinged air outlet has a flap-type air outlet, and the door and frame can be opened and closed freely, which is convenient for installation and matching use of filters. It is often used for return air in guest rooms.
Self-vertical louver type air outlet This air outlet is used for automatic exhaust in air-conditioned rooms with positive pressure. Normally, the louvers at the air vents naturally droop under their own weight, isolating outdoor air exchange. When the indoor air pressure is greater than the outdoor air pressure, the airflow will blow the louvers open and exhaust air outwards. On the contrary, when the indoor air pressure is less than the outdoor air pressure, the airflow cannot flow into the room in the reverse direction. , the air outlet has a one-way check function.
The square diffuser is suitable for broadcast studios, hospitals, theaters, classrooms, concert halls, libraries, offices, etc. In order to prevent people from noise interference and discomfort in various environments, in addition to determining the neck wind speed according to performance, the installation height and occasion also need to be considered.
Circular diffusers are usually installed on the ceiling. The airflow they blow out is of a flat delivery type, and its structure is a multi-layer cone type.
The swirling air outlet sends out a rotating jet, which has the characteristic of inducing attenuation faster than high wind speed. In air conditioning and ventilation systems, it can be used to supply air with large air volume and temperature difference to reduce the number of air outlets. Installed on the ceiling, it can be used for low spaces within r
meters, and can also be used for air supply in large areas at medium heights, even up to r
meters or more.
