1.7 Air dryer on SF Full-Feature (Fig. 1.15)

Compressed air circuit

Wet 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 (11) where the refrigerant evaporates and withdraws heat from the air. More water in the air condenses. The cold air then flows through condensate separator (3) where the condensate is separated from the air. The condensate is automatically drained through outlet (5). The cold, dried air then flows through heat exchanger (13), where it is warmed up by the incoming air.

Refrigerant circuit

Compressor (M1) delivers hot, high-pressure refrigerant gas which flows through condenser (9) 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 (11) 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.
