A refrigeration cycle having a coefficient of performance of 3.0 maintains a computer laboratory of 18 C on a day when the outside temperature is 30 C. The thermal load at steady state consists of energy entering through the walls and windows at a rate of 30,000 kJ/h and from the occupants, computers, and lighting at a rate of 6,000 kJ/h. Determine the power required by this air conditioner and compare this with the minimum theoretical power required for any refrigeration cycle operating under these conditions, each in kW.
