An adiabatic compressor used in a refrigeration system compresses R-134a at P equal to 180 kPa and superheated by 2.73C to a pressure P equal to 600 kPa. Please answer the following questions. a. For an adiabatic and reversible compression, determine the final temperature of the compression, in C. Represent the process on a T-s diagram including the relevant isobars. b. For the adiabatic and reversible compression determine the compression work. Would you consider your result to be equal to the minimum work per unit mass that a R-134a compressor will require to operate between P and P? c. Now you wish to compare the adiabatic and reversible compressor against an actual compressor operating between the same pressures and inlet conditions for which the temperature at the exit of the compressor is equal to 50C. Determine the enthalpy at the exit of the actual compressor and the work per unit mass needed for the compressor. d. Determine the isentropic efficiency of the actual compressor.
