An air-conditioning unit has a cooling capacity of 18,000 Btu/h. If the unit has a rated energy efficiency ratio (EER) of 11, how much electrical energy is consumed by the unit in one hour? If a power company charges 12 cents per kWh for usage, how much would it cost to run the air-conditioning unit for a month (31 days), assuming the unit runs eight hours a day?
What will be an ideal response?
energy input to the unit = 1,636 Wh = 1.636 kWh
The cost to run the air-conditioning unit for a month for a period of 8 hours a day is
calculated in the following matter.
