Description
Compressor (1) delivers hot, high-pressure refrigerant gas which flows through condenser (4)
where most of the refrigerant condenses.
The liquid flows through the refrigerant filter (6) to Expansion valve/capillary (7). The refrigerant
leaves the capillary tube at evaporating pressure.
The refrigerant enters evaporator (8) 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 (1).
