144V DC Compressor, an Efficient Solution for EV Air Conditioning System
The core of an air-conditioning system for an electric vehicle is its compressor. Guchen GC27A144 27cc 144V electric compressor is a
variable speed compressor, which provides a reliable solution for EV AC system. It consists of an inverter, a high-speed brushless DC motor, rotating scroll and fixed scroll, oil-gas separator etc. Each component of the compressor have been innovatively designed and fully validated individually.
◆
An inverter is used to precisely regulate the temperature via controlling the motor speed - slowing down or speeding up depending on the real-time climate demands of the EV. Variable-speed inverter technology reduces power consumption, making GC27A144 144V air conditioning compressor a higher energy-efficiency solution for EVs.
◆
Brushless DC motor is used to drive the compressor. It has variable speed ranges 1000-5000rpm, and can be regulated smoothly. The electric motor is featured by good regulation performance, high speed and electronic control.
◆
Scroll type compressor: one scroll is fixed, whereas the other scroll is moving. Refrigerant is compressed through the moving scroll in a smooth motion. The 144V scroll compressor is with higher efficiency and quiet operation, being a reliable solution for EV AC System.
They are finally coupled together making up an electric all-in-one compressor unit to ensure the overall cooling performance of EV air conditioning system.
