Ref
rigeration dryers of ID type contain high efficient refrigerant R410A of the HFC
group
Compressor (5) delivers hot, high-pressure refrigerant gas which flows through condenser (6) where
most of the refrigerant condenses.
The liquid refrigerant flows through liquid refrigerant dryer/filter (7) to capillary tube (8). The
refrigerant leaves the capillary tube at about evaporating pressure.
The refrigerant enters evaporator (2) where it withdraws heat from the compressed air by further
evaporation at about constant pressure. The heated refrigerant leaves the evaporator and is sucked in
by the compressor
(5) through a liquid separator (12).
By-pass valve (9) regulates the refrigerant flow. Fan (10) is switched on or off by switch (11) depending
on the pressure degree of the condensate.
