(1) The double-layer louver air outlet is generally used as an air outlet, and can also be used directly with the fan coil. It is widely used at the end of the centralized air conditioning system, and can also be used with a split multi-leaf regulating valve to adjust the air volume.


(2) The single-layer louver air outlet can be adjusted up and down, the return air outlet can be combined with the air outlet filter, the angle of the blade can be adjusted, and there is an ABS plastic fixed bracket between the blades. The fixed filter can be taken out of the slideway during cleaning, and then pushed into the slideway after cleaning to continue to use.


(3) The fixed strip tuyere is used in heating and cooling air-conditioning systems and can be installed on side walls or ceilings.


(4) Automatically exhaust air-conditioned rooms with positive pressure from self-hanging louvered tuyere. Under normal circumstances, the louvers relying on the tuyere sag naturally to isolate the indoor and outdoor air exchanges. When the indoor air pressure is greater than the outdoor air pressure, the airflow blows the louvers out and exhausts it. Conversely, when the indoor air pressure is less than the outdoor air pressure, the airflow cannot reverse Flowing into the room, the tuyere has a one-way check function.


(5) The diffuser is a commonly used air supply port in the air conditioning system. It has a uniform diffused characteristic and a simple and beautiful appearance. It can be made into a square or a rectangle according to the requirements of use, and can meet the decoration requirements of any ceiling. The inner core part of the diffuser can be detached from the outer frame, which is convenient for installation and cleaning. The air outlet adjustment valve can be equipped in the back to control and adjust the air volume. It is suitable for broadcasting studios, hospitals, theaters, classrooms, concert halls, libraries, entertainment halls, theater lounges, general offices, shops, hotels, restaurants, and gymnasiums. In order to make people 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 occasion.


(6) The spherical adjustable tuyere is a nozzle-type air supply vent. The high-speed airflow sends air to the specified direction through the valve body spout. The jet direction of the airflow can be conveniently adjusted in the conical space with a vertex angle of 35 °. The gas flow can also be adjusted by the degree of valve opening and closing. It is used for high-speed air supply or local cooling in tall floors, such as airport waiting halls, indoor stadiums, hotel kitchens, etc.


(7) The swirling air outlet sends out a rotating jet, which has the characteristics of large induction ratio and fast wind speed decay. It can be used as a large air volume in the air-conditioning ventilation system and a large temperature difference to reduce the number of air outlets. The low space within 3 meters can also be supplied with two kinds of heights and large areas, and the height can even reach more than 10 meters. Swirl tuyere can be installed not only in public places with large floor height (such as industrial plants, airports, theaters, bank business halls, etc.), but also indoors with floor height ≥ 380m (such as conference rooms), especially suitable for sending The place where the temperature difference of wind changes from -10K + 15K.
