DAMPER TYPES

34

Responsible for pumping refrigerant through the air conditioning system and increasing the pressure of incoming refrigerant gases. Located under the hood. Belt driven. Problems with inadequate lubrication inside the compressor are the cause of excessive wear, contamination and the spread of particles throughout the A/C system.

MANIFOLD

Connects the suction and discharge lines to the compressor.Metal particles adhering to the internal walls are evidence of system-wide contamination.

54

CONDENSER

Heat exchanger responsible for changing refrigerant from ahigh-pressure gas state to a high-pressure liquid state through principles of condensation. Located in front of radiator. The small passages inside the condenser are very susceptible to clogging from the particles that enter under high pressure.

LIQUID LINE

Moves the high-pressure liquid through the system. Particles frequently cling to the interior walls and catch other particles as they flow through.

64

ORIFICE TUBE

Responsible for regulating refrigerant flow to the evaporator and changing refrigerant pressure from high to low. Located under the hood.

65

ACCUMULATOR

Responsible for storing excess refrigerant not utilized byevaporator, filtering contaminants out of refrigerant and removing any moisture that is in system. Located under the hood. Due to the concentrations of particles that are trapped here, the accumulator frequently requires replacement.

EVAPORATOR

Responsible for changing state of refrigerant fromlow-pressure liquid to low-pressure gas through principles of evaporation. Located in the passenger compartment. In all but the most serious instances of system contamination, the evaporator is the one major component that does not need replacement. Any particles that reach the evaporator tend to flow through.
