Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 mpa and leaves as superheated vapor at 0.8 mpa and 60°c at a rate of 0.058 kg/s. determine the rates of energy transfers by mass into and out of the compressor. assume the kinetic and potential energies to be negligible. the enthalpies of refrigerant-134a at the inlet and the exit are 239.19 kj/kg and 296.82 kj/kg, respectively.

17.21kW and 13.97kW

Explanation:

To solve this question we have two data that are provided to us and correspond to the Enthalpy.

The energy in mass and enthalpy terms is given by.

Where the variables are,

We only proceed to replace the values.

Energy transfer rate by mass in the compressor is 13.97kW

Being analogs for the other part of the cycle,

Substituing,

Energy transfer rate by mass out of the compressor is 17.21 kW
