Electric Vehicle Air Conditioning Compressor
Our Electric Air Conditioning Compressor (EACC) incorporates a permanent magnet synchronous motor, directly powered by the vehicle's high-voltage battery. As the core power component for both in-vehicle cooling and auxiliary heating (in a heat pump system), it ensures comfortable interior temperatures while maximizing energy efficiency and extending the vehicle's driving range.
Description
If you're looking for the electric vehicle air conditioning compressor, welcome to wholesale the product from our factory. As one of the leading manufacturers and suppliers in China, we will offer you the best service and fast delivery. Now, check the quotation with our seller.
Electric Vehicle Air Conditioning Compressor
Product Introduction
The mechanical structure (usually a scroll type) is driven by a built-in high-voltage permanent magnet synchronous motor (or brushless DC motor) to draw in low-pressure gaseous refrigerant, compress it into high-temperature and high-pressure gas, and then discharge it to the condenser.
Structural composition: It is an integrated unit consisting of a compressor housing, a scroll compressor mechanism, a motor, and a controller (Inverter), and can operate independently of the engine.
Key Advantage
Key Advantages
Energy Saving and Variable Frequency: Utilizing electric control, it can adjust speed according to demand, significantly reducing energy consumption.
Quiet and Efficient: Employing a scroll-type structure, it features low noise, low vibration, and high cooling efficiency.
Intelligent: Controlled by the vehicle control unit (VCU), and combined with heat pump technology, it achieves efficient thermal management of the passenger compartment and battery.
