An actual refrigerator absorbs 500 kJ of heat from a sink at 250 K and reject 660 kJ of heat to environment at 300 K. T0 = 300 K. the heat transfer processes are reversible. Determine The entropy generation s for the refrigerator, in kJ/K. The irreversibility of the device, in kJ and The exergy deposited in the TL cold space, in kJ.
