Question
b) Refrigerators are systems that are used to remove heat from a cooled space then reject
heat to a space of higher temperature. Consider a refrigerator operating at normal
conditions, removing heat from a cool space at a rate of 150 kJ/min to ensure the
refrigerated space is kept at -5 °C. If the surrounding air is at 27 °C and assuming that
the refrigerator is operating as a Carnot cycle, determine:
1)
The rate of heat being rejected to the surrounding in kJ/min
The coefficient of performance of this refrigeration process
11)
111)
The minimum required power on this process (give your answer in kW)
