HVAC(Heating, Ventilation and Air Conditioning)

Hanon Systems’s broad collection of HVAC architectures combines optimized heat exchangers with globally supplied, standardized components to provide a tailored solution to meet customer requirements for comfort and cost-effective function. Hanon Systems’s vehicle and systems experience are advantageous when providing thermal management for vehicle occupants and automotive manufacturers. Leading edge design and validation tools deliver fast product development, while Hanon Systems’s global manufacturing footprint and capabilities enable it to better serve customers worldwide. Hanon Systems offers new, innovative HVAC architectures, including ultra-flat HVAC and straight airflow path HVAC, in addition to traditional HVAC architectures.

  • Ultra-Flat HVAC

    Hanon Systems has developed an ultra-flat HVAC for innovative utilization of unused or unconventional package space in the floor pan or body sides. When designed as a main unit, it can be completely relocated out of the cockpit for greater flexibility in cabin styling and roominess. As a rear auxiliary unit, the flat HVAC provides rear occupant comfort and improved airflow performance without penalizing cabin space.

  • Super Slim HVAC System

    The Super Slim HVAC system, which obtained a New Excellent Technology(NET) certificate from the Ministry of Knowledge Economy in 2012, is the world’s first technology that allows reducing the physical size and weight of HVAC by integrating each of the airflow and temperature control rotary doors, which are crucial cooling components in HVAC, into a sliding door. Since it affects on vehicle architecture in an efficient way, it can secure broader interior and buffer space of the vehicle and, which will reduce damages and improve safety in case of a crash with pedestrians. Therefore, Hanon Systems has acquired the technology responding to Euro NCAP Pedestrian Protection.

  • Straight Airflow Path HVAC

    This unique straight air flow path HVAC architecture provides efficient, high airflow to quickly heat or cool vehicle occupants. Less pressure loss through the straight air ducts allows a smaller blower motor for improved fuel efficiency and quieter a/c operation. Its compact package gives more cabin space and greater cockpit design flexibility whether applied to luxury vehicles or today’s smaller cars.

Hanon Systems’s compressor is a key component of air-conditioning system and functions like the heart of a person. It is operated by force originating from the vehicle engine, and repeats a cycle of inhalation, compression and circulation of the refrigerant. It compresses low-pressure and low-temperature gas from the evaporator, converts it into high-pressure gas and relays it to the condenser. Hanon Systems is manufacturing 3 types of compressors such as Fixed Type (HS), Variable Type, and Rotary Suction Valve Type Compressors. Hanon Systems also manufactures the Electric Compressors, which are being developed by our advanced eco-friendly technology.

  • Fixed Swash Plate Compressor

    HS Compressor which has been Hanon Systems’s first development compressor is fixed swash plate type. It maintains the constant compression ratio and discharge rate of refrigerant. Also, HS Compressor is able to adjust the cooling load through the on/off function of Clutch that is compressor’s component. It has been one of the Hanon Systems's competitive products as a low-cost product.

  • Rotary Suction Compressor

    Hanon Systems’s rotary suction compressor has a fixed displacement swashplate design that draws refrigerant through the center shaft. It delivers improved fuel economy by creating less suction loss compared to a traditional suction valve. The fixed-angle sliding plate mechanism drives five low-friction, double-acting pistons that prevent seizure under extreme operating conditions. The integral pulse reducing design and available integrated mufflers reduce pressure pulses and improve NVH.

  • Variable Swash Plate Compressor

    Hanon Systems's variable swash plate compressor can vary its duty cycle and change the amount of displaced refrigerant. This appropriate sizing of compressor displacement improves power consumption and fuel economy. To meet consumer demand for cabin cooling, available electronic controls provide consistent discharge air temperature, independent of drive conditions. Passengers feel more comfortable without a chance for over dehumidification

  • Electric Compressor

    For traditional internal combustion vehicles, the air conditioning compressor is driven by a belt connected to the engine; therefore, it can only operate when the engine is running. Electric and hybrid vehicles operate under different conditions that preclude conventional compressor designs. For both “green” vehicle applications, Hanon Systems has developed an innovative solution – the electric compressor.
    Hanon Systems’s state-of-the-art design includes an efficient scroll compressor controlled by an on-board electric motor and integrated power electronics. The electric compressor operates independently, enabling the cabin to be cooled even when the engine is off. Its compact design fits within the traditional belt-driven compressor package space, minimizing vehicle complexity in platforms that offer hybrid-electric model variants.

Fluid Transport

Hanon Systems’s fluid transport portfolio consists of refrigerant lines, coolant lines, transmission oil cooler lines, accumulators, receiver driers and internal heat exchangers (IHX) FT. Applications include underhood and underbody lines for cars, trucks, hybrid and electric vehicles. Also available is a portfolio of customer fittings, including an innovative, patented metal seal fitting (MSF) FT that stops refrigerant from leaking into the environment. Industry leading design and global manufacturing capability has resulted in Hanon Systems becoming the largest automotive fluid transport supplier. Hanon Systems is relentlessly pursuing improved passenger comfort and fuel economy while reducing carbon emissions. Combined with a global manufacturing footprint, Hanon Systems provides customers with a superior performing product at a low cost.


Hanon Systems's climate controls offer automatic and manual front and rear temperature controls that operate the Heating, Ventilation and Air Conditioning System (HVAC). Through advanced development tools and hardware/software standardization, Hanon Systems is committed to delivering innovations that meet the market demands for reduced cost, high consumer perceived quality, improved occupant comfort, new Human-Machine Interaction (HMI) solutions and rapid development.


A cluster ion generator known as ‘CLIOGEN’ developed with domestic technology is a product which can completely remove chronic odors that are being generated from the use of Air-Conditioner/Heater. It provides pleasant driving environment through its ability to remove over 90% of the steam from the fan, bacteria and floating germs. An Air-Filtration device with application of CLIOGEN has already proven its outstanding superiority at ‘IR52 Jang Yeong Sil Award’ in 2009. Presently, it is applied on most of the luxury cars from Hyundai and Kia Motors namely, Genesis, Grandeur TG and YF Sonata. Air contains a number of minute pollutants that can be harmful to people's health, such as heavy metals that are less than O.5㎛, tire dust and soot. Hanon Systems's Air Filter prevents the inflow of airborne particles of over O.3㎛ that can be harmful to the people, while supplying fresh air to the driver and passengers.

Cooling Module

The cooling module consists of a radiator, condenser, and fan & shroud. In particular, as an integrated module, it reduces the labor and time needed to the airconditioning system and helps to ensure optimal performance through strict quality-control inspect ion of each modular component.

  • Condenser

    Located at the very front of an auto engine compartment, the condenser cools and converts the heated and high-pressure refrigerant received from the compressor into a liquid form. The condenser can be installed separately or integrated into a cooling module with the radiator.
