Consider a building whose annual air-conditioning load is estimated to be 120,000 kWh in an area where the unit cost of electricity is $.10/kWh. Two air conditioners are considered for the building.
Air conditioner "A" has a seasonal average COP of 3.2 and cost $5500.00 to purchase and install.
Air Conditioner "B" has a seasonal average COP of 5.0 and cost $7000.00 to purchase and install.
All else being equal, determine which air conditioner is a better buy.
