1, the insulation function:

The air curtain makes it difficult for customers, such as restaurants, shops and entertainment, to keep in and out of the door. This can be 60-80% efficiency to keep the indoor cold, warm air temperature. But will only allow a slight temperature change.

2, pest control function: can be found most of the annoying insects can not pass through the wind curtain wall. This can be better and easier to keep fruit counters, fast food restaurants and other places of health.

3, dust-proof function: If the precision machinery factory or the face of the bus shop in the food store or clothing store hall installed in the air curtain, you can effectively shield the dust outside, to 60-80% level to keep clean The

4, fresh function: air curtain can prevent from the chemical laboratory or store storage room and frozen meat machinery exudes a strange smell. And can block the harmful emissions of vehicles outside the gas. How to prevent air conditioning cold, hot air outflow, the experts made the proposal: air curtain with air-conditioning combination of organic use, can effectively solve the air conditioning cold, hot air outflow of these problems.

5, anion function to produce reactive oxygen species, improve lung function, promote metabolism, improve sleep, sterilization, make fresh air, smoke and dust, prevent myopia, static to prevent hair split.

6, remote control function Many brands are coupled with infrared receiver function of the wind curtain machine. But in the application is not very popular, because the wind curtain machine than the wind curtain to change the temperature from time to time.

Product selection points

1. Air curtain selection of the main control parameters for the rated air volume, noise, export wind speed, installation height, installation and so on.

2. Air curtain unit classification, characteristics

3. A hot air curtain should be set when one of the following conditions is met:

1) located in cold areas, cold areas of public buildings and industrial buildings, often open the door, and no fighting and front room;

2) public buildings and industrial buildings, when the production or use requirements are not allowed to reduce the indoor temperature or when compared with the technical economy set hot air curtain reasonable.

4. Air curtain air temperature should be ≤ 50 ℃. High outside the door air temperature ≤ 70 ℃. The export wind speed is generally 4 ~ 9m / s.

5. Use the air curtain, should pay attention to export wind speed and noise two indicators. These two indicators directly reflect the merits of product quality. The noise of the air curtain (sound pressure level) does not exceed the limits specified in Table 1.

6. Hot water, steam air curtain working environment temperature of 5 ℃ ~ 40 ℃, relative humidity <90%.

7. Electric air curtain working environment temperature -10 ℃ ~ 40 ℃, relative humidity <90%. There is one of the following circumstances, can not use the electric air curtain: a corrosive gas; flammable and explosive places; dust larger; steam diffuse condensation; can damage the electrical insulation of the gas or dust.
