Problem 2.069 SI 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 0.7 kW and has a coefficient of performance of 5.5. Determine the rate that energy is removed from the room air, in kw. If electricity is valued at $0.1/kW·h, determine the cost of operation for 24 hours of operation. ▼ Part A...
