A window-mounted room air conditioner removes energy by heat transfer from a room and rejects energy by heat transfer to the outside air. The air conditioner cycle requires a power input of 0.434 kW and has a coefficient of performance of 6.22.
1. Draw a schematic of the system and label and show the direction of all energy rate terms.
2. Determine the rate that energy is removed from the room air, in kW.
3. If the air conditioner is left on over the weekend (full 2 days) how much energy in does the AC use?
