Features Tour

HVAC Components
  • Blower
  • Control Electronics
  • Air Filter
  • Expansion Valve
  • Orifice Tube
  • Evaporator
  • Heater Core

The drive motor and fan propels the air within the cabin through the HVAC system.

Control Electronics

Regulates the blower power and speed.

Air Filter

Cleanses the air of pollutants and helps prevent the windows from soiling.

Orifice Tube
+ Expansion Valve

The orifice tube expands the refrigerant and decreases its pressure. The expansion valve controls the drop in pressure of refrigerant evaporation and cold generation, the flow rate, and the output temperature.


Works for the cabin air conditioning to cool and dry the airflow entering the vehicle, reduces air humidity levels, and ensures efficient windshield demisting.

Heater Core

The heater core is an air/water exchanger using engine cooling coolant heat to increase the cabin temperature, and demist and defrost the windshields.
