An air conditioner running with R-134a on a cycle executed under the saturationdome between the pressure limits of 0.8 MPa and 0.12 MPa. Calculate themaximum Coefficient of Performance of this heat pump.

The COP of the system is = 4.6

Explanation:

Given data

Higher pressure  = 1.8 M pa

Lower pressure = 0.12 M pa

Now we have to find out high & ow temperatures at these pressure limits.

Higher temperature corresponding to pressure 1.8 M pa

°c = 335.9 K

Lower temperature corresponding to pressure 0.2 M pa

°c = 262.9 K

COP of the system is given by

COP = 4.6

Therefore the COP of the system is = 4.6

attach the statements so i can answer : )
