An ideal air-conditioning system uses R134a as the refrigerant. The compressor has an inlet pressure of 20 psia and an exit pressure of 260 psia with a mass flow rate of 0.6 lbm/s.
Refer to Fig. 10.17 and determine:

(i) The lowest cycle temperature
(ii) The highest cycle temperature
(iii) The cooling load from the evaporator
(iv) The heat rejection from the condenser
(v) The compressor horsepower
(vi) The coefficient of performance for the system
