Question

A standard vapor compression system produces 70.4 kW of refrigeration using R-12
as a refrigerant while operating between a condenser temperature of 42 °C and an
evaporator temperature of –25 °C.
2.1 Draw the p-h diagram of the cycle. 
2.2 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 m3
/s.
