1.5 Air dryer on GA Workplace Full-feature
(Figs. 1.2 and 3.5)
GA Workplace Full-feature are provided with a dryer which
removes moisture from the compressed air.
1.5.1 Compressed air circuit (Fig. 1.2)
Compressed air enters heat exchanger (13) and is cooled by
the outgoing, cold, dried air. Water in the incoming air starts
to condense. The air then flows through heat exchanger/
evaporator (15) where the refrigerant evaporates causing the
air to be further cooled to close to the evaporating temperature
of the refrigerant. More water in the air condenses. The cold
air then flows through separator (3) where all the condensate
is separated from the air. The condensate collects in
condensate trap (4) and is automatically drained. The cold,
dried air flows through heat exchanger (13), where it is warmed
up by the incoming air. Condensation in the air net cannot
occur unless the air is cooled to below the pressure dewpoint.
1.5.2 Refrigeration circuit (Fig. 1.2)
Compressor (M3) delivers hot, high-pressure refrigerant gas
which flows through condenser (2) where most of the
refrigerant condenses.
The liquid flows through liquid refrigerant dryer/filter (12) to
capillary tube (7). The refrigerant leaves the capillary tube at
evaporating pressure.
The refrigerant enters evaporator (15) where it withdraws heat
from the compressed air by further evaporation at constant
pressure. The heated refrigerant leaves the evaporator and is
sucked in by the compressor.
