Optimized Electronic Expansion Valve Control for Automotive Air Conditioning

Modern automotive air conditioning performance depends heavily on the precision of its control valves. With over 25 years of specialization, we design and manufacture high-efficiency electronic expansion valve (EEV) control systems that enhance energy efficiency, reliability, and passenger comfort.

Why Electronic Expansion Valves Are Replacing Mechanical Systems

As vehicles become more electrified, traditional mechanical expansion valves are being phased out in favor of intelligent electronic systems. Our adaptive EEV controllers adjust valve opening in real-time based on operating conditions—improving system Energy Efficiency Ratio (EER) by over 15%.

Core Technologies in Our EEV Control Systems

1. Adaptive PID Control Strategy

Our algorithm dynamically tunes valve control based on evaporator superheat and compressor load, ensuring precision under all conditions.

2. Multi-Sensor Fusion Technology

We integrate temperature, pressure, and humidity sensors to improve system accuracy and response time.

3. Fault Diagnosis & Self-Repair

Built-in intelligence detects common faults and makes automatic adjustments to ensure continuous operation.

Performance Benefits

• 15%+ improvement in Energy Efficiency Ratio (EER)
• 12% reduction in energy consumption
• Faster cooling and better cabin temperature uniformity
• Reliable operation with self-diagnosis features

Our systems are already used by leading global automotive manufacturers in their latest models.
