Basic situation of energy consumption of air compressor

The electricity cost of air compressors generally accounts for more than 40% of the total electricity cost of the factory. Most production environments have fluctuations in air demand, ranging from 40% to 100%, and users always choose air compressors based on the maximum gas consumption.

Ordinary air compressors meet the fluctuation of air demand by maintaining a high pressure throughout the system, adjusting the opening degree of the intake valve (throttling) to adjust the air volume at partial loads, and venting at low loads (no-load operation), all of which result in energy waste at low air consumption.





energy saving principle

The AEDV frequency conversion series air compressor from Aineng has leading frequency conversion technology. By changing the motor speed, it accurately tracks the user's gas demand and meets the user's gas demand while maintaining stable exhaust pressure. When the user's gas consumption decreases, it reduces the national speed and energy consumption. When there is little or no gas consumption, the motor can completely stop running to avoid energy consumption caused by motor idling. The AEDV variable frequency series air compressor perfectly combines the displacement of the compressor with the user's air consumption, completely avoiding energy loss caused by compressor throttling (capacity adjustment) control or ON/OFF control, and can reduce energy consumption by up to 35% or even more.




Pioneers in energy conservation and emission reduction, allowing users to benefit from advanced technology:
Accurately changing the motor speed according to the user's gas consumption, reducing system pressure, and greatly saving energy consumption;
Eliminating the inefficient process of capacity (throttling) regulation under partial load;
Maintain pressure fluctuations within the range of 0.1 bar to stabilize pipeline pressure;
► Reduced the average working pressure, eliminating the need to choose a P-press machine that is 1-2 bar higher than the system pressure;
Low system pressure reduces system leakage;
Variable frequency starting avoids electrical shock, allowing for unlimited start stop cycles;
► Avoiding the energy consumption of ordinary air compressors during no-load operation.

●Advanced frequency conversion technology, stable and reliable, seamlessly integrated with the compressor

The frequency converter used in the AEDV variable frequency series air compressor adopts cutting-edge vector control technology, which has unparalleled advantages:
► Precise control of the electromagnetic torque of the motor, so that the motor can ensure the appropriate torque to drive the compressor smoothly with minimal loss (motor temperature rise) within an extremely wide speed range;
Excellent technical platform, enabling the input power factor of the motor to reach 0.92 or above;
Efficient DC/AC inverter conversion reduces energy consumption and improves reliability, while minimizing noise and harmful harmonics;
► Configure high-power inverter power module with super overload capability;
► Standard equipped with DC reactors, effectively improving the power factor on the input side, eliminating the influence of high-order harmonics on the frequency converter on the input side, and reducing external conduction and radiation interference;
► High reliability and long-life design, the variable frequency body allows operation in environments up to 50 ℃, suitable for long-term heavy-duty work;
► It has a comprehensive safety self diagnosis function and provides users with multiple fault protections.

●Advanced control functions

Advanced control, monitoring, and communication systems maximize the overall efficiency and reliability of air compressors while minimizing maintenance costs, while also providing remote control and communication capabilities.
