3- Three refrigerators in Figure 4, shown with the designations A, B, and C are working in a temperature range of TH=32 °C and T1=3 °C. Among these three refrigerators, while the first refrigerator (A) is known to be a reversible, on the other hand, the other two (B and C) are known to be an irreversible and an impossible type, respectively. So, a) Calculate the COPR value of the refrigerator A under these temperature limits. b) Based on your Carnot calculations, give a COPR value for B which can be accepted as an irreversible refrigerator. And discuss why the value that you had chosen can be chosen as an irreversible refrigerator COP value. c) Again, based on your Carnot calculations, give a COPR value for C which can be accepted as an impossible refrigerator.
