2. ( 15 points) Your process will need to recycle the ammonia. An equipment vendor has a process to return the ammonia to the thermodynamic state that supplies the freezer in a three-step process. First, the ammonia vapor is compressed to \( 1200 \mathrm{kPa} \) and \( 140^{\circ} \mathrm{C} \). Second, the ammonia is passed through a heat exchanger where it is cooled and condensed to saturated liquid at \( 1200 \mathrm{kPa} \). Third, the liquid is adiabatically throttled (passed through a valve to reduce pressure) to \( 120 \mathrm{kPa} \). a. How much heat must be removed by the condenser? b. Calculate the final quality of the throttled ammonia. c. Will this equipment work for your process? How might it be modified to make it work if it doesn't meet your needs?
