Technical Description

TrueDRY DR90/DR120 uses a refrigeration system similar
STRAINER/FILTER
COMPRESSOR
DRIER
to an air conditioner to remove heat and moisture from
incoming air and add heat to the air that is discharged.
Hot, high-pressure refrigerant gas is routed from the
compressor to the condenser coil. The refrigerant is
CONDENSER
cooled and condensed by giving up its heat to the air that
is about to be discharged from the unit. The refrigerant
CAPILLARY
liquid then passes through a filter drier and capillary tubing
TUBES
which causes the refrigerant pressure and temperature to
drop. It next enters the evaporator coil where it absorbs
heat from the incoming air and evaporates. The evaporator
EVAPORATOR
operates in a flooded condition, which means that all the
ACCUMULATOR
evaporator tubes contain liquid refrigerant during normal
operation. A flooded evaporator should maintain nearly
M27404
constant pressure and temperature across the entire coil,
from inlet to outlet.
