Instructions by student:
Design a vapor-compression refrigeration system using
r134a capable of cooling a space to a temperature of -
25 °C with a lifting capacity of 10 kW. The system must
be able to reject heat to surroundings with a maximum
temperature of 40 °C. The maximum pressure ratio
across a compressor is 5 with an isentropic efficiency
of 90%. Determine a) the heat rejected at the
condenser and b) the refrigeration system's coefficient
of performance (COP). Bonus, demonstrate you have
developed a design which maximizes performance
under the prescribed conditions (10 pts).
