Return air grilles classification

(1) Double louvered tuyere is usually used as a gas supply port. It can also be used directly in fan coils. It is widely used at the end of centralized air conditioning systems. It can also be used with multi-leaf control valves to regulate air volume.

(2) The single-layer blinds can be adjusted to the up and down wind direction, and the return air outlet can be used together with the tuyere filter. The blade angle can be adjusted and the ABS plastic mounting bracket is placed between the blades. After cleaning the fixed filter, remove the filter from the slide, then clean it, then push it in from the slide and continue to use it.

(3) The fixed air vent is used for heating and cooling of the air conditioning system and can be installed on the side wall or ceiling.

(4) The air-conditioned room with positive pressure of the louver vents is automatically ventilated. Typically, the louvers of the tuyere naturally hang down and sag, thereby isolating the air exchange between the interior and exterior. When the indoor air pressure is greater than the outdoor air pressure, the air blows the louver and vents outward.

(5) The diffuser is a common air supply port in an air conditioning system. It has uniform flow characteristics and a simple and aesthetic appearance. It can be made square or rectangular according to the requirements of use, to meet the decoration requirements of any ceiling. The inner core portion of the diffuser can be removed from the outer frame for ease of installation and cleaning. The rear can be equipped with a tuyere regulating valve to control the air volume. Suitable for broadcast studios, hospitals, theaters, classrooms, concert halls, libraries, entertainment halls, theatre lounges, general offices, shops, hotels, restaurants and stadiums. In order to avoid noise interference and discomfort in various environments, in addition to determining the neck wind speed according to the performance table, it is also necessary to consider the installation height and installation occasions.

(6) The spherical adjustable air outlet is a nozzle type air supply port. The high-speed airflow is supplied to the specified direction through the nozzle of the valve body, and the direction of the airflow can be conveniently adjusted in a conical space of 30° in the apex angle. The gas flow rate can also be adjusted by the degree to which the valve opens and closes. It is suitable for high-speed roof air supply or partial cooling, such as airport terminal, indoor stadium, hotel kitchen and other occasions.

(7) The swirling air outlet emits a rotating jet, which has the characteristics of large induction ratio and rapid attenuation of wind speed. It can be used as a large air volume in air conditioning ventilation systems. Large temperature difference air supply can reduce the number of air outlets and can be installed on the ceiling or ceiling. The low space within 3 meters can also be used for two kinds of high-altitude air supply, and the height can even reach more than 10 meters.
