4T--326U NIT/ SYSTEM INFORMATION1.1 WHAT IS AIR CONDITIONINGAir Conditioning is the cooling, heating, dehumidification, andfiltration of the air within the passenger compartment of a vehicle.1.2 SPLIT SYSTEMA 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 systemcomponents, along with specific data for each, is provided inParagraph 1.4.1.3 SYSTEM DESIGNATIONSTie--In System -- Is a Carrier evaporator and condenser connectedto an existing OEM compressor and dash evaporator. The OEMradiator type condenser is normally removed.Max System -- A Carrier system installed along with an existingOEM system. The systems operate independent of each other.Stand--Alone (Standard) System -- All Carrier componentsinstalled on a vehicle. These can be either single or dualcompressor systems.1.4 SYSTEM COMPONENTS (Refer To Figure 1-1)Return Air Thermostat/Sensor -- The system may be suppliedwith a thermostat or thermistor. Both of these devices aretemperature sensitive components which when activated, signalsthe Electro--Magnetic Clutch to engage/disengage. The return airthermostat is normally located in the drivers control panel while thereturn air thermistor is normally located in the return air flow of theevaporator assembly.Electro--Magnetic Clutch -- The Electro--Magnetic clutch controlsthe operation of the compressor. When engaged, the compressorcirculates refrigerant and provides cooling.Compressor -- The compressor is a belt driven, high--pressurepump, which circulates the refrigerant through the evaporator andcondenser . The operation of the compressor is controlled by theElectro--Magnetic clutch.Condenser -- The condenser is normally located in the skirt or onthe roof of the vehicle. Its primary function is to reject heat, whichwas transferred to the refrigerant by the evaporator from thepassenger compartment of the vehicle.
