Heating and Air Conditioning

Radiator and Cap – Radiator uses air flow to dissipate heat from coolant and the rad cap controls system pressure lowering the boiling point.
Orifice Tube / Expansion Valve – Controls refrigerant flow in the A/C system.
Accumulator / Receiver / Drier Tank – Used on low/high pressure side to filter refrigerant.
Condenser – Dissipates heat from refrigerant and changes its state from gas to liquid.
Lines and Hoses – Circulates refrigerant through the system.
Compressor with Clutch – Compresses/pumps refrigerant within the A/C system.
Evaporator – Uses refrigerant to remove heat from the passenger compartment.
Pressure Sensor – Detects refrigerant pressure in the A/C system.
