Refrigerant-134a enters an adiabatic compressor as saturated vapor at -24C and leaves at 0.8 MPa and 60C. When the mass flow rate of the refrigerant is 1.2 kg/s, determine the power input to the compressor.

= 287kW

Explanation:

Knowing the enthalpy data, we have to

So,

Here,

m=mass flow rate

h= Enthalpy of refrigerant at the compressor

Replacing

= 1.2 × 239.16

= 287kW
