Core Functions

1. Convert 312V high-voltage DC power into compression power, compress low-pressure gaseous R134a refrigerant into high-temperature high-pressure gas to complete vehicle refrigeration cycle
2. Built-in intelligent inverter dynamically adjusts compressor rotation speed via CAN bus according to cabin temperature, low power consumption design specially optimized for VF3 small-capacity battery to reduce range loss
3. Independent cooling operation without relying on drive motor operation; stable cold air output during static charging, urban low-speed idle and high-speed driving
4. Auxiliary dual function: Cabin air conditioning cooling + LFP battery passive temperature control heat dissipation to protect battery cycle life in high-temperature tropical environments
5. Multi-layer built-in protection logic: overvoltage, undervoltage, overheat, liquid hammer, locked rotor protection, effectively prevent high-voltage circuit short circuit and compressor burnout

Common Malfunctions Resolved

• No cold air blowing while vehicle high-voltage system starts normally during driving or charging
• Intermittent AC automatic shutdown, central control screen pops up air conditioning system fault warning codes
• Abnormal buzzing vibration noise when compressor starts, severe locked rotor leading to complete cooling failure
• Insufficient cooling capacity, slow cabin temperature drop under high summer ambient temperature
• Compressor CAN communication failure triggering vehicle high-voltage system alarm fault codes
• Refrigerant leakage from compressor shell or pipeline joints resulting in full loss of cooling function

Product Advantages

1. Authentic BENLING OEM dedicated compressor, fully matched VinFast VF3 312V low-voltage communication protocol, no coding mismatch failure after replacement
2. Compact 27cc small-displacement design, low energy consumption, minimizes battery power loss and retains vehicle cruising range
3. One-piece integrated inverter structure, no separate drive board replacement required, greatly shorten maintenance working hours
4. Fully matched original mounting lugs, HV plug and refrigerant pipeline interfaces, zero modification required during installation
5. Strict high-voltage insulation production process, effectively eliminate electric leakage safety risks under long-term urban stop-start driving
6. Two interchangeable supersession OEM numbers cover all VF3 production batches, simplify warehouse spare parts matching and customer lookup efficiency

Installation Guidance

1. Critical HV Safety Step: Complete high-voltage battery discharge & isolation operation following VinFast VF3 official maintenance procedure, wear professional high-voltage insulating protective gloves and clothing
2. Fully recover R134a refrigerant from the whole vehicle AC circuit through dedicated refrigerant recovery machine
3. Remove front bumper and lower radiator guard plate to expose compressor assembly position
4. Disconnect high-voltage HV plug first, then separate refrigerant pipeline joints and compressor fixing bolts in sequence
5. Install new Benling compressor, lock all pipeline joints and HV connectors per factory specified torque standard
6. Evacuate AC system with vacuum pump for minimum 90 minutes to fully remove internal pipeline moisture
7. Refill specified capacity R134a refrigerant and matched volume POE refrigeration oil according to VinFast VF3 service manual parameters
8. Reactivate vehicle high-voltage power supply system, use VinFast dedicated diagnostic scanner to clear AC and high-voltage related fault codes, complete compressor communication matching calibration
9. Test cooling effect under static charging, idle and driving conditions respectively, inspect all pipeline connection positions for refrigerant leakage
