Refrigerant 134a is the working fluid in an ideal vapor-compression refrigeration cycle that communicates thermally with a cold region at 0°C and a warm region at 26°C. Saturated vapor enters the compressor at 0°C and saturated liquid leaves the condenser at 26°C. The mass flow rate of the refrigerant is 0.08 kg/s.
Determine:
(a) The compressor power
(b) The refrigeration capacity
(c) The coefficient of performance
(d) The theoretical maximum refrigeration coefficient of performance
