REFRIGERANT FLOW DIAGRAM
LD06385
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 shell.
Low pressure vapor enters the compressor where pres-
sure and superheat are increased. The high pressure va-
por is fed to the Air-cooled condenser coil and fans where
the heat is removed. The fully condensed liquid enters the
economizer. The subcooled refrigerant then passes
through the expansion valve where pressure is reduced
and further cooling takes place before returning to the
cooler.
