NF Air Conditioning Compressor For Electric or Hybrid Vehicle

Electric air conditioning compressor is the core standard configuration of air conditioning/thermal management systems for all electrified vehicle models, and it is also an important component for the upgrade of hybrid/fuel vehicles. The core application is applied to electric vehicle models without engine direct drive power, and also covers some energy-saving fuel/hybrid models. It is suitable for all categories of vehicles from passenger cars to commercial vehicles and special vehicles, and different specifications (vortex/blade, high pressure/low pressure, ordinary/heat pump special) will be matched according to the usage scenario and temperature control requirements in different vehicle models. The core application revolves around the two core requirements of cabin temperature control and vehicle thermal management.
1、 Core application models (covering all categories, with electric models as the absolute mainstay)
1. Pure electric vehicles (passenger cars+commercial vehicles)
Pure electric passenger vehicles: From micro mobility scooters (Wuling Hongguang MINIEV) to mid to high end sedans/SUVs (Tesla, BYD, NIO, etc.), the entire series is equipped with a high-pressure electric air conditioning compressor (mainstream vortex type for passenger cars), which is the only power source for cabin cooling/heat pump heating, and works together with BTMS to provide high-temperature auxiliary cooling for the power battery;
Pure electric commercial vehicles: electric buses, electric heavy-duty/light-duty trucks, logistics vehicles, equipped with large displacement and high-pressure blade type electric compressors, suitable for the high load requirements of commercial vehicles with large cabin space for rapid temperature control and ultra large capacity battery fast charging and cooling, while also considering the stability of all-weather operation.
2. Plug in/range extender vehicles (mainstream household passenger cars)
For example, BYD DM-i, Ideal ONE, Wenjie M5, etc., although they have engines, they are equipped with electric air conditioning compressors as standard to achieve independent operation of the air conditioning in pure electric mode (without engine belt drive during parking/low-speed pure electric driving). They also support mechanical and electric dual-mode switching during engine operation, balancing energy saving and cabin comfort.
3. Energy saving fuel/mild hybrid vehicles (MHEVs)
Some joint venture/self owned fuel vehicles (such as Toyota Corolla mild hybrid and Volkswagen Lavida energy-saving models) are equipped with low-pressure electric air conditioning compressors to reduce engine load and improve fuel economy, decoupling the air conditioning system from the engine. When parked, the air conditioning can be turned on separately to enhance the driving experience.
4. Special electric vehicles
Electric sanitation vehicles, electric forklifts, electric construction vehicles, electric RVs, airport shuttle buses, etc., are matched with customized electric compressors according to working conditions (such as anti vibration models for construction vehicles and low-noise energy-saving models for RVs) to meet the cabin temperature control and equipment auxiliary cooling needs in special scenarios.
2、 Core application scenarios (in car+vehicle grade full operating conditions, dual core cooling/heating)
The application of electric air conditioning compressors covers all working conditions of vehicle driving, parking, and fast charging, with the core functions of cooling, heat pump heating, and auxiliary temperature control. It is a dual guarantee of vehicle comfort and core component safety:
1. Cabin cooling (basic core application)
The universal essential requirement for all car models is that during high temperatures in summer, the compressor drives the refrigerant circulation to transfer the heat inside the car to the outside, achieving rapid cooling of the cabin. It is suitable for all scenarios such as urban commuting, long-distance driving, and parking rest, solving the problem of high temperature and stuffiness inside the car.
2. Heat pump heating (core application of energy-saving in new energy vehicles)
Exclusive core scenario for new energy vehicles, during low temperatures in winter, the compressor serves as the power core of the heat pump air conditioning system. By switching the refrigerant circuit through a four-way valve, low-grade heat energy from the outside air is "transported" to the interior for heating, with energy consumption only 1/3~1/2 of PTC heaters. This significantly reduces the range degradation of winter heating for new energy vehicles and is suitable for medium and low temperature environments above -5 ℃; When the temperature is below -5 ℃, it works in conjunction with PTC heaters to balance heating speed and energy saving.
3. Auxiliary temperature control for core components of the vehicle (for automotive grade safety applications)
As an important component of the vehicle thermal management system, the compressor provides a cold source for the core components of the vehicle, ensuring stable operation of the equipment
Power battery assisted cooling: During fast charging/high load driving, the power battery generates heat at high speed. If the water cooling efficiency is insufficient, the compressor provides a cold source for the BTMS to quickly reduce the battery temperature and avoid thermal runaway;
Motor/Electronic Control Refrigeration: When the vehicle is traveling at high speeds or climbing hills, the drive motor and vehicle controller generate a large amount of heat, and the compressor provides a cold source for their cooling circuit to ensure the normal operation of the power system;
Car mounted equipment refrigeration: providing a cold source for RV onboard refrigerators, engineering vehicle onboard electrical control equipment, etc., to meet the exclusive equipment requirements of special vehicles.
