With the growing attention to environmental protection and CO2 emissions reduction, new energy vehicles are developing rapidly in the world. Pure electric vehicles and hybrid electric vehicles have been assigned a top priority in the further development of the worldwide new energy vehicle industry. Consequently, the needs for highly reliable and efficient electrically-driven compressors
are also increasing, to match with the air conditioning system of electric vehicles.
DQ34A350 Electric AC Compressor Basics
DQ34A350 electric compressor is dedicated designed by Guchen EAC Team
. It is a 350 volt high-voltage air conditioner compressor with super high efficiency, providing sufficient thermal comfort to the passenger compartment of electric vehicles.
The electric air conditioner compressor mainly comprises a scroll compressor
, an electric motor, and a drive controller.
: adopting latest variable speed technology
. It is used to compress R134a refrigerant of the HVAC system in electric vehicles.
Three-phase Electric Motor
: During operation, the ac compressor is driven by brush-less permanent magnet motor which is integrated into the EV's high voltage network.
Drive Controller: the variable frequency drive controller controls the inverter to provide a variable speed for precise temperature control and high efficiency.
