Q2/ A refrigerator with tetrafluoroethane (R-134a) as refrigerant operate with an evaporation temperature of -34 °C and a condensation temperature of 18 °C. Saturated liquid refrigerant from the condenser flows through an expansion valve into the evaporator, from which it emerges as saturated vapor. What is the coefficient of performance (COP) of the refrigerator? (Note: The cycle is vapor compression cycle).
