Find out what your air conditioner is costing you with energy calculator. Calculate the daily or monthly usage cost of your AC air conditioning unit. The AC Operating Cost is based on the factors like Equipment Size, Electric Rate Cost, Cooling Hours and SEER (Seasonal Energy Efficiency Ratio).
Formula Used:
Energy Consumed Watts = ( Equipment Size / SEER ), Energy Consumed (kWh) = Energy Consumed Watts / 1000, Cost = Energy Consumed (kWh) x Hours x Electric Rate.
Example:
How much does it cost to run a weight of 1 ton air conditioner for 5 hours per day, 168 hours per month, SEER as 10 and electric rate as 7?
Solution
Energy Consumed Watts = ( 12000 / 10 ) = 1200 Watts
Energy Consumed (kWh) = 1200 / 1000 = 1.2 kWh
Cost / day= 1.2 x 5 x 7 = Rs. 42
Cost / month = 1.2 x 168 x 7 = Rs. 1411.2
