What is climate control?
Did you know the automotive climate control system is ranked ahead of anti-lock braking systems (ABS), aerodynamics and diesel engines as the most innovative technology in automotive history*? * By Channel 4, a British public-service television broadcaster
Automotive climate control by definition refers to the car’s integrated heating, ventilation and air conditioning system. Other manufacturers’ names for this include climatronic or intelligent air conditioning. As implied by the name, “automotive climate control” is the technology that creates ambient comfort within the vehicle.
Initially achieved through the use of ice plates, air conditioning went electric in 1902 thanks to the work of the American engineer, Willis Carrier. This paved the way for GM’s Cadillac division to introduce the first built-in air conditioner in 1939, and for Chrysler to introduce the first trunk-mounted system in 1953, using a refrigerant known as R22.
Today, suppliers of automotive climate control technologies are constantly challenged in three core areas: increasing environmental pressures, changing market/industry needs and rising customer/consumer expectations. Accordingly, priorities have grown to encompass not only the technology itself, but also passenger comfort, eco-friendliness and fuel efficiency – the key drivers of Hanon Systems's research and development activities.

What are the main roles that climate control play?
What are the key roles that climate control plays?
Provides fresh air from outside the vehicle into the cabin
“Re-circulation” function which takes in cabin air and sends it through the HVAC back into the cabin
- Purifies polluted air or removes unpleasant odors
- Reduces “time-to-comfort”
- Improves efficiency/ reduces system energy consumption
Heats the air with a heater core or another heating device
Cools the air with an evaporator and a refrigerant buffer
De-humidifies the air by first cooling it and then re-heating it to the desired comfort temperature

What is powertrain cooling?
How does Powertrain Cooling relate to Climate Control?
What is the Thermal Management System?
Why does an electric vehicle require thermal Management?
One method through which an engine can understand that it’s getting close to overheating involves lithium ion batteries. As their name suggests, these are batteries that are charged and discharged by the movement of lithium ions through an electrolyte. If the temperature moves out of the optimum working range, the conductivity of the electrolyte decreases, indicating that the engine needs to be cooled down.

Air Conditioning System (=A/C System = Climate control):
Modern climate control systems offer additional features for enhanced occupant comfort
- Multi-zone HVAC system - allowing up to four individual temperature zones in a vehicle
- Auxilliary HVAC module - a second unit to provide better comfort for rear occupants, especially in large vehicle cabins such as vans or SUVs
- Heat pump system - a very energy-efficient way to provide heating from a modified refrigerant system, already used for electric vehicles
- Cabin air quality features - better filteration, ionization, fragrancing of cabin air for enhanced health and well-being
ICE Thermal Management
Enables an optimum operating temperature for the cooling of additional devices by using:
- Automatic transmission oil
- Engine oil of high performance motors
- Exhaust gas recirculation (EGR) cooler for better exhaust emissions
- Charge air cooler (air- or water-cooler designs), etc
Electrified Vehicle Thermal
Powertrains of full electric and hybrid electric vehicles pose modified and new requirements:
- A low-temperature coolant circuit for the electric motor and inverter
- Active cooling of the lithium batteris
- A heat pump system for cabin heating
