An air-conditioning system with R134a as the working fluid operates on an ideal vapor compression refrigeration cycle. The working pressure of the evaporator and the condenser are 200 kPa and 1.0 MPa, respectively. The refrigerant flow rate is 0.03 kg/s.
a) Draw the process cycle on a T-s diagram with labels.
b) Determine the power input and COP of the system.
c) Determine the tons of refrigeration.
d) What is the SEER rating of the system?
e) What is the size of the system in hp .
f) What is the maximum COP based on the reversed Carnot cycle operates at the same temperature range? Determine the percent of increment of the COP compared to the ideal cycle.
g) Suggest ways to improve the COP of vapor compression refrigeration cycl
