The heat pump is a refrigeration system that uses the heat released by the condenser to heat the regulated environment. The heat pump type electric vehicle air-conditioning compressor GCH20A72 developed by Guchen has the advantages of compact structure, intelligent speed regulation, low noise and high efficiency, safety and reliability. This product 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.
