A standard vapor refrigeration cycle using CO₂ operates with the following characteristics: Evaporator temperature is -15°C and the compressor (isentropic efficiency 0.85) draws saturated vapor. Condenser pressure is 7 MPa, and the throttle draws saturated liquid. Power to drive the compressor is 1.2 kW a) Make a table with the values of pressure, temperature, and enthalpy at the corner points. b) Make a list of the process elements and determine heat and work per mass for each sub-process. c) Determine the COP of the cycle and the cooling power. d) Determine the mass flow rate of CO₂.
