Balance on Compressor

Just like the evaporator, the compressor is an open system, at steady state, with kinetic and potential energies negligible. The energy balance calculations are similar to the ones for the evaporator.

balance for steady state

 In the compressor case, Q and Wb both equal zero.
0=0-Ws-0+mH1-mH2

 Ws=m(H1-H2)
