UNIT/SYSTEM INFORMATION
1.1 WHAT IS AIR CONDITIONING
Air Conditioning is the cooling, heating, dehumidification, and filtration of the air within the passenger compartment of a vehicle.
1.2 SPLIT SYSTEM
A Split System normally includes an Evaporator(s), a Condenser(s) a Compressor(s) and interconnecting refrigerant hoses, fittings, and electrical harnesses and controls. A listing of the system components, along with specific data for each, is provided in Paragraph 1.4.
1.3 SYSTEM DESIGNATIONS
Tie--In System --Is a Carrier evaporator and condenser connected to an existing OEM compressor and dash evaporator. The OEM radiator type condenser is normally removed.
Max System --A Carrier system installed along with an existing OEM system. The systems operate independent of each other.
Stand--Alone (Standard) System -- All Carrier components installed on a vehicle. These can be either single or dual compressor systems.
1.4 SYSTEM COMPONENTS (Refer To Figure 1-1)
Return Air Thermostat/Sensor -- The system may be supplied with a thermostat or thermistor. Both of these devices are temperature sensitive components which when activated, signals the Electro--Magnetic Clutch to engage/disengage. The return air thermostat is normally located in the drivers control panel while the return air thermistor is normally located in the return air flow of the evaporator assembly.
Electro--Magnetic Clutch --The Electro--Magnetic clutch controls the operation of the compressor. When engaged, the compressor circulates refrigerant and provides cooling.
Compressor --The compressor is a belt driven, high--pressure pump, which circulates the refrigerant through the evaporator and condenser . The operation of the compressor is controlled by the Electro--Magnetic clutch.
Condenser --The condenser is normally located in the skirt or on the roof of the vehicle. Its primary function is to reject heat, which was transferred to the refrigerant by the evaporator from the passenger compartment of the vehicle.
