Classification of air curtain machines Natural air curtain machines are mainly used in high-temperature and hot areas such as Central China and South China. The main goal is to stop the outflow of indoor cold air in summer, with simple structure and mature products. Generally, there is no heater to block the air outlet, so the wind and air volume are sufficient and the hanging height can be higher.

The hot air curtain machine is mainly electric heating, and PTC heater is installed at the air outlet for airflow heating, which is mainly used to block indoor hot air outflow in winter in North China, Northwest China and Northeast China. However, the density and volume of the heater at the air outlet are large, which leads to low air outlet speed and small air volume.

Dual-purpose air curtain machine uses the water of central air conditioning system as cold and heat source, and can use the cold water of central air conditioning system for refrigeration in summer and heating in winter. Compared with the general electric heating air curtain machine, it increases the cooling function in summer, thus expanding the efficiency of the air curtain machine.

According to the application situation, ordinary air curtain machines are suitable to be installed in quiet places such as hotels, hotels, office buildings, conference rooms, hospitals, shopping malls and other places with large traffic, as well as cold storage and constant temperature storage logistics centers.

Special-shaped air curtain machine is difficult for ordinary air curtain machine in some occasions, but in order to better pursue the effect of heat preservation and energy saving, some special air curtain machines will be customized according to the actual situation. Such as arc door air curtain machines and elevator air curtain machines.

Nonstandard air curtain machine nonstandard air curtain machine is also nonstandard air curtain machine. The standard air curtain machine specifications are generally 0.9 m, 1.2 m, 1.5 m. If customers need non-standard air curtain machines, they need to contact the manufacturer for customization.

According to the direction of air supply, an upward air curtain is installed at the upper part of the door, which is simple to install, does not occupy the building area and does not affect the architectural beauty. The sanitary condition of air supply airflow is good, which is suitable for general public buildings and is the most promising form.

The side air curtain is installed at one side of the doorway and divided into one side and two sides. Do not open the door inward. For industrial buildings, when the width of the external door is less than 3M, unilateral air supply should be adopted; When the width of the outer door is 3~ 18M, unilateral or bilateral air supply or top-down air supply should be adopted.

Downward air curtain is installed under the ground, and the wind-proof efficiency is the best when cold air invades from the lower part of the door opening in winter, which is not affected by the direction of opening the door. But it is easy to be blocked by stolen goods, and the downward airflow is easy to raise clothes, so it is rarely used.
