33 DAMPER TYPES 33

34 DAMPER TYPES 34

35 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. COMPRESSOR 35

54 MANIFOLD Connects the suction and discharge lines to the compressor. Metal particles adhering to the internal walls are evidence of system-wide contamination. 54

55 CONDENSER Heat exchanger responsible for changing refrigerant from a high-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. 55

56 CONDENSER 56

57 CONDENSER TYPE 57

58 CONDENSER TYPE 58

59 SUB-COOL CONDENSER 59

61 SUB-COOL CONDENSER 61

62 SUB-COOL CONDENSER 62

63 CONDENSER COOLING 63

64 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

65 ORIFICE TUBE Responsible for regulating refrigerant flow to the evaporator and changing refrigerant pressure from high to low. Located under the hood. 65

66 ACCUMULATOR Responsible for storing excess refrigerant not utilized by evaporator, 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. 66

71 REFRIGERANT VOLUME ADJUSTING 71

72 BOX TYPE EXPANSION VALVE 72

73 EXPANSION VALVE 73

74 EVAPORATOR Responsible for changing state of refrigerant from low-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. 74
