I am trying to design refrigeration cycle with propylene refrigerant. I am planning to use heat exchanger for subcooling of liquid and superheating of vapor. I choose centrifugal compressor and water-cooled type of condenser. Evaporating temperature is -38C. It is needed to cool down light hydrocarbons from -26C to -35C. Could you please check the datas I wrote?
In Pressure-Enthaply
A - after condenser (0.62 MPa , 5C)
A* - after subcooling HE (0.62MPa, -10C)
B - after throttling valve (0.16MPa, -38C)
C - after evaporator (0.16 MPa, -38C)
C* - after superheating HE (0.16MPa, -14C)
D - after compressor (0.62 MPa, 50C)
E - condenser (0.62 MPa, 5C)
