Features and Effects of Air Curtain


Effects of

Air Curtain Installation

Open Effects

Since the door can be opened at any time, access of customers is easy, resulting in effects of higher sales increase.

Circulation

Effects

Can circulate the indoor cooling/heating most effectively with circulation of indoor air by wave of air curtain.

Inspect

Repellent

Maintain higher health and hygiene standards by blocking harmful insects bearing pathogens.

Warm/Cool

Effects

Keeps hot air or cold air in the store with 60 ~ 80 efficiency, minimizing temperature change.

Anti-Vibration

Effects

Create a pleasant indoor environment by blocking harmful air such as fine dust and yellow dust.

Safety

There is no concern for children’s hands getting caught in the entrance door since it enables operation of business with the door opened.


Analysis of Thermal Efficiency & Economic Feature of Air Curtain

Understanding on Temperature Difference between Inside and Outside

Temperature change occurs between inside and outside due to air-conditioning inside the room in summer. When pressure difference occurs at the entrance/exit as shown in the following table. When the temperature difference between indoor and outdoor gets bigger, the power of wind will enter the room more strongly. There will be higher inflow and outflow of heat due to pressure of the jet flow. If the air curtain is installed to prevent this phenomenon, it catches the pressure formed by temperature difference. The model of air curtain shall be selected in consideration of the temperature difference and height.

Wind Speed Change according to Temperature Difference



There is little difference of pressure in the center and large difference on the upper and the lower part.

Wind is generated by pressure difference, resulting in inflow and outflow of heat naturally.


Analysis of Thermal Efficiency & Economic Feature of Air Curtain

Energy saving effect generated by installation of air curtain is as follows.

If it is installed at the automatic door, the efficiency may increase further to reach 90% or higher or result in higher effects.
