(6) An R-12 standard refrigeration cycle operates at an evaporating pressure of 386 kPa and a condensing pressure of 1009 kPa. Show the effects of decreasing the vaporizing pressure to 270 kPa on the following: For a unit mass, (a) refrigerating effect, (b) COP, and (c) work. For a refrigerating capacity of 1 kW, (d) power, (e) mass flow rate, (f) heat rejected, and (g) volume flow rate.
