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.
