Inquiry
The electric compressor is the core of the new energy vehicle air conditioning system. It integrates the motor, controller and compressor into an organic whole. It has good automatic control performance and realizes information exchange with the vehicle control system. It is an important implementation of intelligent vehicle environmental engineering unit. The heat pump type electric vehicle air-conditioning compressor developed by Guchen improves the efficiency of the heat pump cycle and solves the problem of electric vehicle heating and defrosting in extremely cold areas that consume a lot of electricity. After the provincial and ministerial level scientific and technological achievements are firm, its technical indicators have reached the international advanced and domestic leading levels.
Guchen heat pump type electric air-conditioning compressor LDH27A72AB is suitable for all cars with DC72V DC power supply.

Outstanding feature of Low Voltage Electric Compressor
  • Integrated structure: Scroll compressor, permanent magnet brushless DC motor, drive controller is composed of 3 parts, the motor and drive controller get a cryogenic gas refrigerant for good cooling.
  • Oil separator mechanism: The refrigerated oil is separated from the gas refrigerant in the oil separator, circulates in the compressor, improves lubrication, reduces the heat exchanger resistance of the air conditioning system, and increases the refrigerating capacity of the air conditioning system by 5-10%.
  • Ring pin anti-rotation mechanism: simple structure, high reliability, low noise, low cost.
  • Vortex profile with variable cross section: thick inner wall, high compressive strength, thin outer wall, the displacement can be made larger under the same vortex height.
  • Aluminium light-weight construction, compact scroll compressor, this can save the vehicle space, easy installation, also save material and reduce power consumption.
  • Robust designed, long-lasting electromotor, reliability performance, and the vehicle air-conditioning compressor can operate in the harsh conditions.
  • Have a good shock resistance performance, the vehicle can bump on the rough roads and it would not damage the vehicle air conditioning.
  • A large speed range, the compressor have a greater cooling capacity and higher efficiency whatever the compressor in any conditions.
  • The refrigeration compressor with very economical, and have a long service life.
