Swirl air vents can send out rotating jets, with the characteristics of high induction ratio and fast wind speed attenuation. They can be used as large air volume and large temperature difference air supply in air conditioning and ventilation systems to reduce the number of air vents. They are installed on ceilings or ceilings and can be used for low spaces within 3 meters, or for two types of high altitude large-area air supply, with heights even exceeding 10 meters.

The swirl air vents produced by De Leng Air Conditioning Equipment Factory can be divided into two types: manual swirl air vents and electric swirl air vents.

Manual swirl air outlet: It is necessary to manually adjust the corresponding angle to supply air.

Electric actuator type: The electric swirl air outlet can be controlled by a switch, and the 220V electric control adjusts the blade to adjust the air volume and freely adjust the air supply angle..

Temperature controlled type (temperature sensing type): The neck of the temperature sensing swirl air outlet is equipped with a temperature sensing actuator, which can automatically sense the temperature of the airflow and automatically drive the inner blades to change the air supply angle. When the summer air supply temperature is ≤ 17 ℃, the blades can automatically adjust to the cooling mode, and the airflow is blown out horizontally; When the winter air supply temperature is ≥ 27 ℃, the blades can automatically adjust to the heating mode, and the airflow is blown out in a vertical direction. Can meet the air supply requirements under different working conditions in winter and summer. Temperature sensing actuators do not require manual labor or power or electrical control equipment, and have advantages such as energy saving, environmental protection, stable performance, easy installation, and maintenance free.
