Just answer letters D, E, and F. Thank you.
Transcribed Image Text:1. A standard refrigerating system with a heat exchanger is operating with a condenser pressure of 1571.2 kPa and
evaporator pressure of 421.35 kPa using refrigerant R22. If the liquid line from the condenser is soldered to the
suction line from the evaporator to form a heat exchanger and if as a result of this, the saturated vapor leaving
the evaporator is superheated by 10.
Determine
(a) temperature of refrigerant entering the compressor
(b) temperature of refrigerant leaving the compressor
(c) degree superheat leaving the compressor
(d) temperature of subcooled liquid leaving heat exchanger
(e) degree subcooled leaving the heat exchanger
(f) mass of flash gas per kg refrigerant entering evaporator
(g) compression ratio
(h) clearance volumetric efficiency of compressor if the
clearance volume is 5%
