An air conditioning unit has a cooling capacity of 24,000 Btu/hr. If the unit has a rated energy efficiency ratio (EER) of 11, how much electrical energy is consumed by the unit in 1 h? If a power company charges 14 cents per kW-hr usage, how much would it cost to run the air conditioning unit for a month (31 days), assuming the unit runs 8 hrs a day? What is the coefficient of performance (COP) for the given air conditioning unit?
What will be an ideal response?
We compute the energy consumption of the given air conditioning unit
Energy input to the unit for one hour of operation = 2181 W-hr = 2.181 kW-hr
The cost to run the unit for a month for a period of 8 hours a day is calculated in
the following manner:
