Question:

A vapor-compression refrigerator using R-134a has a maximum pressure of 120 psia and a minimum pressure of 15 psia. The R-134a leaves the condenser as a saturated liquid and leaves the evaporator as a saturated vapor. The compressor is reversible and adiabatic. Determine:

(a) The maximum room temperature,

(b) The minimum food-compartment temperature, and 

(c) The coefficient of performance.
