HVAC 835 HVAC Refrigerant flow through A/CSystem is as follows: (1) Compressor draws Low pressure, heat laden vapour refrigerant from the Evaporator. (Suction port - large line), and compresses the vapour. (2) High pressure, heat laden vapour from the compressor goes into the Condenser. The vapour gives up its latent heat to the cooler outside air through the Condenser and changes back to liquid due to condensation. Now it is a high pressure liquid. (3) The high pressure liquid now encounters an orifice (small opening) either an Orifice tube or Expansion Valve. When the liquid passes through this opening, its pressure is reduced and it gets very cold. (4) The lowpressure sub cooled liquid absorbs heat from the cabin through the evaporator and the liquid inside turns into vapour (like water absorbing heat and turning to steam) (5) This Low pressure, heat laden vapour from the evaporator is now drawn into the compressor and cycle continues to flow.
