In a vapor-compression refrigeration cycle, ammonia exits the
evaporator as saturated vapor at -22 °C. There are
irreversibilities in the compressor. The refrigerant enters the
condenser at 16 bar and 160 °C, and saturated liquid exits at 16
bar. There is no significant heat transfer between the compressor
and its surroundings, and the refrigerant passes through the
evaporator with a negligible change in pressure.
