Consider a vapor-compression refrigeration cycle that uses R134a as the working fluid. The condenser, which yields saturated liquid, is operated at 45C; the evaporator, which yields saturated vapor, is operated at -10.C. The compressor is 80.% efficient. Using data from the table below, determine:
1. The amount of cooling per kg of R134a
2. The amount of heat rejected per kg of R134a
3. The coefficient of performance.
