Automotive HVAC (HVAC is abbreviation for heating, ventilation and air conditioning systems) is a system consisting of three sub-systems that all work together to provide conditioned air to the cabin. The heating part can raise the temperature inside the car using heat from the engine. The ventilation part moves and directs the air within the cabin. And the air condition part can remove the heat from the car by cooling and dehumidifying the air with a refrigerant.
Automotive HVAC can make the drivers and passengers feel comfort and make driving pleasure, especially when the climate is harsh. The key components of a complete automotive HVAC system include heater core, thermostat, blower fan, HVAC controls, condenser, compressor and evaporator.
