Answer :
The rejected by the air conditioner system is 2.75 kilowatts.
An air conditioner system involves a refrigeration cycle. It uses power to get heat from the cold reservoir before sending it to the hot reservoir. The model is described by the First Law of Thermodynamics:
QL+W-QH=0
Where:
QL- Heat rate from the cold reservoir, measured in kilowatts.
QH = Heat rate liberated to the hot reservoir, measured in kilowatts.
W = Power input, measured in kilowatts.
The heat rejected is now cleared:
QH=QL+W
If QL=2kW and W=0.75kW
QH=2.75kW
The rejected by the air conditioning system is 2.75 kilowatts.
