Hose/Line HVAC: Description and Operation

A/C REFRIGERANT LINES DESCRIPTION

NOTE:  Replacement of the receiver/drier is not required when repairing the air conditioning system except when there is physical evidence of system
contamination from a failed A/C compressor or damage to the suction accumulator.

The condenser to evaporator line contains the high pressure liquid refrigerant upstream of the A/C evaporator core orifice.

The compressor manifold tube assembly is attached to the A/C compressor and has the following features:

-

The upstream side contains low pressure refrigerant gas.

-

The downstream side contains high pressure refrigerant gas and a fitting used to mount a serviceable high pressure A/C charge port valve.

-

The downstream side also contains a fitting used to mount the A/C pressure cut-off switch. A long-travel Schrader-type valve stem core is installed
in the fitting so that the A/C pressure cut-off switch can be removed without discharging the A/C system.
