34CC 2KW Electric Scroll Automotive A/C Compressor
Product Description
This electric scroll compressor is a core integrated component specifically developed for the air conditioning and thermal management systems of new energy vehicles. Unlike traditional belt-driven mechanical compressors, it adopts a fully electric direct-drive design, integrating a high-efficiency permanent magnet synchronous motor, a precision scroll compressor mechanism, and a built-in intelligent variable frequency drive module into a compact unit.
This EV Air Conditioning Compressor features continuous variable frequency speed regulation, enabling precise stepless adjustment of cooling and heating capabilities. It supports cabin cooling and heat pump heating functions, perfectly meeting the thermal management needs of pure electric vehicles, hybrid vehicles, and special engineering vehicles. Thanks to its optimized scroll gear design, it ensures stable operation, high energy efficiency, and strong durability even under extreme vehicle operating conditions.
Product Advantage
1. High-efficiency scroll compression structure: Utilizes an interlocking static and dynamic scroll plate, eliminating reciprocating motion and the need for intake and exhaust valves. The continuously variable volumetric compression process ensures high volumetric efficiency and stable exhaust pressure, effectively improving the overall coefficient of performance (COP).
2. Integrated motor and inverter design: Built-in high-power-density permanent magnet motor and intelligent drive controller, eliminating the need for complex external transmission structures. Supports CAN bus communication and analog signal control, enabling seamless integration with the vehicle ECU for intelligent operation.
3. Ultra-low vibration and noise: The scroll plate's orbital motion replaces the traditional piston reciprocating motion, significantly reducing operating vibration and noise, and substantially improving vehicle ride comfort.
4. Wide operational adaptability: Supports operation over a wide voltage fluctuation range and a wide ambient temperature range (-40℃ to 85℃). Stable operation is possible in both high-temperature summer cooling and low-temperature winter heat pump heating scenarios, adapting to complex vehicle driving conditions.
5. High reliability and long service life: Fewer vulnerable parts and a compact sealing structure reduce the failure rate. Stringent automotive-grade manufacturing standards ensure excellent impact resistance, corrosion resistance, and long-term operational stability.
6. Environmentally friendly refrigerant compatibility: Fully compatible with mainstream automotive refrigerants, including R134a and R1234yf, meeting global environmental protection and automotive industry emission standards.
