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. Please, make it typeable, written in virtual text, do not do it by hand and do not take a photo, it interferes with the understanding of the lyrics.
