Low pressure liquid refrigerant enters the cooler and

is evaporated and superheated by the heat energy ab-

sorbed from the chilled liquid passing through the

cooler shell. Low pressure vapor enters at the compres-

sor where pressure and superheat are increased. The

high pressure vapor is fed to the air cooled condenser

coil and fans where the heat is removed. The fully con-

densed and subcooled liquid passes through the expan-

sion valve where pressure is reduced and further cool-

ing takes place before entering to the cooler.
