(2) A standard vapor compression system produces 20 tons
of refrigeration using R-12 as a refrigerant while operating
between a condenser temperature of 41.6 C and an evaporator
temperature of -25°C. Determine (a) the refrigerating effect in
kJ/kg, (b) the circulating rate in kg/s, (c) the power supplied,
(d) the COP, (e) the heat rejected in kW, and (f) the volume flow
rate in L/s.
Ans. (a) 100.26 kJ/kg, (b) 0.7022 kg/s, (c) 25.69 kW,
(d) 2.74, (e) 96.09 kW, (f) 92.18 L/s
