Air curtain principle and classification

First, the principle of air curtain machine

The air curtain machine uses a special high-speed motor to drive a cross-flow, centrifugal or axial-flow wind wheel to create a powerful airflow barrier, effectively maintaining the indoor and outdoor air environment, effectively keeping indoor air clean and preventing cold. Hot air convection, reducing the energy consumption of air conditioners, preventing the intrusion of dust, insects, and harmful gases. It is installed at the entrances and exits of factories, shops, restaurants, cold storage, hotels, airports, stations, etc., and all places with air conditioners. Provide a comfortable working, shopping and leisure environment.

Second, the classification of air curtain machine (air curtain):

1, according to the use of functions: air curtain machine is divided into natural wind and cold and warm, heat can be divided into water heat and electric heat (air curtain);

2, according to the motor and wind wheel structure: air curtain machine can be divided into cross flow, axial flow, centrifugal (air curtain)

3. According to the diameter of the wind wheel: the air curtain machine is divided into 90mm, 125mm, 130mm and 150mm, etc., the size is different, and the generated air volume is also different;

4. According to the installation height: the air curtain machine can be divided into 125, 15, 20, 25, 30, 45, etc., corresponding to the installation height: 2.5 meters, 3.0 meters, 3.5 meters, 4.0 meters, 4.5 meters, 5 meters or more;

5, according to the length of the fuselage: air curtain machine can be divided into 900mm, 1000mm, 1200mm, 1500mm, 1800mm, etc.;
