A window-mounted room air conditioner removes energy by heat transfer from a room and rejects energy by heat transfer to the outside air. For steady -state operation, the air conditioner cycle requires a power input of 0.434kw and has a coefficient of performance of 6.22.
a) Determine the rate that energy is removed from the room air, in kW.
b) If electricity is valued at $0.1/kW*h , determine the cost of operation for 24 hours of operation.
