Homework Statement
The temperature in a refrigerator evaporator coil is -6oC and that in the condenser coil is 22oC. Assuming that the machine operates on the reversed Carnot cycle, calculate the COPref , the refrigerant effect per kW of input work, and the heat rejected to the condenser.
Answers: 9.54, 9.54 kW, 10.54 kW
Homework Equations
The Attempt at a Solution
COPref = 1/((TH/TL)-1)
CoPref = 1/ (28/627)
COPref = 9.53
I have no idea how to find the the input of work and the heat rejected. Could you please help? Thank you.
