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).

1st Step: Evaluate the performance of the Refrigerator 1.Refrigerator 1 operates as a reverse Carnot cycle using R-717 as the refrigerant at aflow of 1.8 kg/s. The condensing and evaporating temperatures are 25 °C and -5 °C, respectively.To evaluate the performance of Chiller 1, you must determine the following performance parameters:project:a) Rate of heat elimination in the condenser (Q );b) The power of the compressor;c) The COP of the cycle.For the energy balance, make the following considerations:- Permanent regime;- Variation of kinetic energy and potentials are negligible;- Compressor and turbine operate adiabatically;- Evaporation and condensation steps do not involve work.
