How to correctly distinguish different types of air curtains?

According to the type of fan, it is divided into tubular type, centrifugal type and axial type air curtain.

Centrifugal air curtain machine, the air outlet is more concentrated, the air flow enters from one end (along the axis), and then discharges from the vertical direction, so the wind pressure is relatively large, suitable for large spaces.

Axial air curtains, the airflow enters from one end and flows out in the same direction, not vertically. Axial flow air volume is large, suitable for places with low height and large space.

The cross-flow air curtain is usually a motor. The airflow enters from the direction perpendicular to the axis and is discharged from the opposite direction. The wind pressure is small, the wind speed is uniform, and the noise is small.

We can see that each type of air curtain has different principles and characteristics, and the applicable occasions are also different. In addition to the common fixed model parameters, special-shaped air curtains can also be customized, such as the models of air curtains above the turnstiles of shopping malls. Therefore, before purchasing an air curtain machine, you need to consult professional staff to provide you with more professional advice, so that you can use it more comfortably and save energy.

What is the value of the existence of the air curtain?

Because the air curtain machine can blow out high-speed airflow, one can be used for indoor temperature regulation, and the hot and cold air blown out can effectively block the influence of outdoor cold and hot air on the indoor temperature; The damper can effectively block outdoor dust, mosquitoes, smoke, etc. from entering the room, keeping the indoor air environment clean.

Due to these two "powerful" advantages, air curtains are widely used in shopping malls, cinemas, hotels, restaurants, gymnasiums and other public places.

How to choose the hot air curtain machine according to the size?

The main function of the air curtain is to seal the door, and the hot air blowing down isolates the exchange of cold and hot air indoors and outdoors. Therefore, the width of the air curtain machine must be at least equal to the width of the door where the air curtain machine is installed, in order to play the role of sealing the door.

For example: the door width is 1.8M, and two machines of 0.9 meters must be configured. If only one 1.5-meter air curtain is configured, it will not play the role of completely closing the door.

Meihao air curtain was chosen before for National Exhibition And Convention Center (Shanghai) phase 1 total about 600pcs.After the great work between Meihao and SCG, This project is been proved to be a great success. Nodaway according to customer needs, National Exhibition And Convention Center (Shanghai) construction department planning to extend the exhibition center.
