Air-conditioning compressors
|
The compressor circulates refrigerant through the air conditioning system. Axial piston compressors are one of the most common types used.
|
Condensers & evaporators
|
The condenser transfers heat from the refrigerant to the outside air. The evaporator draws heat from air in the passenger compartment.
|
Receiver drier
|
The receiver drier acts as a storage volume for liquid refrigerant. It also contains filters and desiccants.
|
Lines & hoses
|
Hoses and pipes must be capable of withstanding the high pressures and temperatures that are found in the air-conditioning system.
|
TX valve construction
|
The thermal expansion valve controls the amount of refrigerant entering the evaporator coils. It also causes a drop in pressure with out causing a change of state.
|
Temperature monitoring thermostat
|
The thermostat monitors the temperature of the evaporator fins and controls system operation within set limits.
|
Refrigerants
|
The refrigerant is used to absorb, transfer and release heat in the air-conditioning circuit.
|
Pressure switches
|
Pressure switches protect the system from excessively high or low pressures. |
Heating elements
|
Most vehicles contain a heated rear window.
|
| Heater cores |
The heater core uses heated coolant to blow heated hair into the passenger compartment of the vehicle. |
