High Voltage (265V~450V) Electric Air Conditioning Compressor

Original price was: $450.00.Current price is: $400.00.

an electric A/C compressor is a crucial component for the air conditioning system. It operates using electricity from the car’s battery to compress and circulate refrigerant, allowing the air conditioning to function without relying on the traditional engine-driven compressor found in internal combustion engine vehicles. This leads to increased energy efficiency and reduced emissions. These compressors are specially designed to meet the specific requirements of electric vehicles, considering their power consumption and overall performance.

 Maximum drive voltage The main power supply voltage shall not be higher than 450VDC, otherwise the controller internal components.
Suction and exhaust pressure connection The torque of the compressor suction and exhaust port of pressure bolt is 11 ± 1 N.M。
 Compressor installation Angle The compressor body should not be tilted (the angle between the compressor main axis and the horizon should not be greater than 5°).
else  The electric compressor shall be avoided in the air outlet of the condenser to ensure adequate cooling of the controller.
 The compressor needs the refrigerant cooling motor and the controller, the suction pipe should be added insulation pipe.
 In order to avoid the insulation drop caused by excessive moisture in the system, the compressor suction and vent should be installed into the closed system immediately (within 5 minutes) after opening.
 The compressor shall be installed with vibration reduction footpad to achieve vibration reduction and noise reduction purposes.
·  The heat dissipation capacity of the condenser should meet the system requirements, and the installation position should have enough heat dissipation space.

·  There is energy storage filter capacitor inside the compressor controller. When high voltage is charged, precharging shall be adopted; otherwise, charged pulse current will cause impact damage to the relay and insurance.

·  Compressor branches recommend separate fuses and are not suitable for combination and use with parts related to vehicle safety (e. g., the same set of relays and insurance).

·  It is recommended to start the condenser fan 6 seconds before the compressor starts to reduce the pipe pressure; After the compressor stops, the condenser fan delays off for 6-10 seconds.

· Under the extreme working pressure and abnormal working pressure, it will increase the failure rate of the compressor and shorten the service life of the compressor.
