Air Curtain is a hygienic processing facility that is designed by mitzvah. The air curtains are suitable for every type of field like- warehouses, restaurants, shopping complexes, malls, salons, offices, etc. to keep the dust, flies, insects, bad odor away while maintaining the inside temperature. If you are looking for energy saving air curtains then, go through the Mitzvah air curtain website www.mitzvah.in.
In this blog, you will get to know how air curtain makes your environment clean and dirt free-
No matter what building you have, whether it’s an office, school, restaurant, or retail store, it can be difficult to prevent heat loss when there is a lot of traffic. For any building with more doors open than closed, energy-efficient air curtains have the potential to significantly reduce energy costs, but how do they work?
Opening or closing doors allow heat (and energy) to escape from the building. Warm air rises and flows out of the open door, followed by cooler air, replacing it at the lower level. Of course, this happens in any room or building, but doors that open and close frequently or stay open all the time can speed up the process. As more cooler/warmer air escapes, your cooling/heating system has to work harder to replace it, increasing your energy bills.
Energy-saving air curtains create airflow through the door, creating a “barrier” between the air inside the building and the air outside. These air curtains often have heating elements that increase the temperature of the air to reduce uncomfortable cold drafts as people pass through an open door.
Using air curtains as a barrier ensures that the energy used to heat the building space is not wasted. This results in an overall reduction in the building’s energy consumption, carbon footprint, and operating costs. In fact, recent research in Finland shows that air curtains can reduce door air leakage by up to 86%.
Do you know air curtains can help us save millions of hard-earned money?
A simple mathematical calculation can prove this. Let’s see how:
Energy Calculation
E = m C ∆T
m: Mass of Air
C: Specific heat of Air at a given Temperature
∆T: Temperature Difference
m = Density X Volume
The density of Air at 40˚C = 1.127 Kg/cu. Meter
C = Specific Heat = 1.005 KJ / (Kg ˚C)
∆T = Temperature Difference = 15˚C
(assuming the outside temperature is 40˚C and the inside is 25˚C)
Volume = Area X Velocity of Air from Door X Time of Opening
(Say : Door Size = 8ft X 4 ft
Velocity = 1 m/s = 200 fpm
Time of Opening = 1 min
Volume = 32 X 200 X 1 = 6400 cu. ft. = 181.22 cu. meter)
m = Density X Volume
(from Above = 1.127 Kg/cu. meter X 181.22 cu. meter
= 204 Kgs)
E = m C ∆T
= 204 kgs X 1.005 KJ / (Kg ˚C) X 15˚C
= 3075.3 KJ = 0.85425 KWh
Thus –
India if Per KWH cost of Power is Rs 8.10
The cost of Opening the Door of Size 8ft X 4ft for 1 min is = Rs 6.92
Cost of Running an Air Curtain of 4 ft = 400W (Input Power) for 1 minute = 6paise
Rate per kWh X Time X Power Input
8.10 X 1/60 X 0.4 = 5.4 paisa
Net Saving = Rs 6.92 – 0.06 = Rs 6.86
Saving per Hour= Rs.7*60min=Rs.420 per Hour
Thus, you can see how Air Curtains help us save Rs. 420/hour. Also, they create a comfortable and amiable environment by keeping mosquitoes, flies, and other pollutants away.
However, air curtains can only deliver on their energy-saving promises if they are properly designed, manufactured, and installed by experts in the field. As with most technologies aimed at reducing waste and increasing efficiency, air curtains must be sized and selected for the application or they will not achieve the desired thermal and energy savings. Therefore, to ensure that your investment is worthwhile, you should definitely use the services of a trusted provider.
