Hose/Line HVAC: Description and Operation
NOTE: Replacement of the suction accumulator/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/drier.
The condenser to evaporator tube contains the high pressure liquid refrigerant upstream of the A/C evaporator core orifice.
The A/C manifold and tube is attached to the A/C compressor with O-ring seals 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.
