Low pressure liquid refrigerant enters the cooler tubes
and is evaporated and superheated by the heat energy
absorbed from the chilled liquid passing through the cooler
shell. Low pressure vapor enters the compressor where
pressure and superheat are increased. High pressure va-
por is passed through the oil separator where compressor
oil is removed and recirculated to the compressor. High
pressure superheated refrigerant enters the condenser shell
where heat is rejected to the condenser water passing

through the tubes. The fully condensed and subcooled liq-
uid leaves the condenser and enters the expansion valve,
where pressure reduction and further cooling takes place.
The low pressure liquid refrigerant then returns to the cooler.
Each refrigerant circuit utilizes a refrigerant to refrigerant
suction line heat exchanger to maximize chiller capacity
and efficiency by subcooling liquid refrigerant delivered to
the expansion valve and superheating suction gas deliv-
ered to the compressor.
