A reversed Carnot engine (refrigerator) has a coefficient of operation (COP) 2.79. The temperature of the cold reservoir is - 29°C. The input power used by this machine is 1235 kJ/h. a) Calculate the heat absorbed from the refrigerator. This engine is converted into a heat engine (Carnot engine); and the temperature of the hot reservoir and cold reservoir is maintained the same. b) Calculate the thermal efficiency of this heat engine.
