Heat leaks from the air in a kitchen through the walls of a refrigerator into the refrigerated cold space at a rate of 1.43 kW. Determine the electrical power required to maintain a steady temperature in the cold space if the refrigerator coefficient of performance is 2.6. Also determine the rate at which heat is transferred to the kitchen air from the refrigerator condenser coil and the net rate at which energy is transferred from the entire refrigerator to the air in the kitchen.
