Factors Affecting AC Power Consumption
Your AC’s use and how much power it takes depend on many things. These include how many people are in the room and the room’s size. Also, the outside and inside temperatures matter. And don’t forget about heat sources like computers or ovens. They add to your AC’s work. Knowing about these factors is your first step to smart power use.
Using the Power Consumption Formula for Cost Estimation
There’s a simple formula to find out how much energy your AC needs.
It is:
Units per month = Maximum Cooling Capacity/ ISEER rating = Result / 1000 = Result X 8 Hrs
= Result X 30 Days
For example, a 1.2 kW AC running 8 hours a day uses about 360 units a month. If one unit costs ₹10, you spend about ₹3600 monthly. But, choosing a more efficient AC can save you a lot of money.
Let’s compare a 3 Star and a 5 Star model. A 5 Star, 1.5-ton AC uses 1.5 units an hour. On the other hand, a 3 Star model uses 1.6 units an hour. Though the difference might not seem big, it adds up over time. Doing a comparison shows the 5 Star AC is better value. It cuts your bill from ₹1000 to ₹1500 a month, with the same usage.
Energy Saving Potential with High Star Rated ACs
