Prоblem 3 – 30 pts Pаrt (а) A vаpоr cоmpression cycle has a mass flow rate of 0.05 kg/s. R-22 enters the compressor (η = 80%) at 2.5 bar, 15 °C and then is compressed to 9.0 bar. The R-22 exits the condenser as a saturated liquid. To approximate entropy: first two decimal places should match (a) 18 pts – Determine the cooling capacity of the cycle (tons) 1 ton = 200 kJ/min PDFs: ME3523_FormulaSheet_Exam3.pdf ME3523_ThermoTables_MoranShapiro_9thEd.pdf
