Refrigerant Flow Diagram
Low pressure liquid refrigerant enters the cooler and is evaporated and superheated by the heat energy absorbed
from the chilled water passing through the cooler tubes. The low pressure vapour is returned to the compressor
where the pressure and temperature are increased. The high pressure and temperature refrigerant vapour enters the
condenser and is condensed. The fully condensed and subcooled liquid refrigerant then enters the throttling device
where pressure reduction and further cooling takes place before returning to the cooler.
