R-134a is compressed in an adiabatic compressor from saturated vapor at 100kPa to a final state at 1 MPa and 50 degrees Celcius. Before entering the compressor, the R-134a receives heat from air in a heat exchanger (evaporator). At the inlet of t he evaporator, the R-134a is at 100kPa and has quality 20%. The air flowing through the heat exchanger can be treated as an ideal gas with cp = 1.00 kJ/kg-K, and decreases 20K in temperature as it transfers heat to the R-134a. Assume that all flows are steady, all changes in kinetic and potential energy are negligible, and the heat exchanger involves no work.
Find:
R-134a temperature at evaporator inlet
R-134a temperature at evaporator outlet
R-134a mass flow rate through evaporator
R-134a mass flow rate through compressor
Phase of R-134a at compressor exit
Work input required for compressor
Air mass flow rate through evaporator
