1. General Overview of the Energy-saving VSD
Schneider Sunshine air compressor VSD series (inverter driven compressor) and YC series (permanent magnetic
variable frequency compressor) is a new-conception energy-saving product. By varying the speed of the drive motor
in accordance to the change of the air capacity required, it regulates the actual power accordingly and thus saves
the energy effectively. By adopting the electronic inverter system and the technology of supplying the exact air
capacity required and precise pressure controlling, SD air compressor not only directly reduces energy consumption
by 30% but also brings many other benefits, such as stabilizing the network pressure, eliminating the peak current
on starting, etc. VSD compressor serves as the best choice for the modern industrial and mining enterprises to
Evaluation and Assessment of the saved energy
While electricity consumed by industrial air compressors accounts for a great part of a manufacturing facility’s total electricity bill, VSD air compressors can provide valuable energy saving for manufactures. However, an accurate assessment of the varying air capacity required before settling on the investment program is indispensable to getting a good return for the investment.
(1) Stable Pressure
The variable speed air compressor adopts PID for precision speed adjustment. Changes in the air amount of
the system will be automatically tracked. The compressor will supply air at a constant pressure, which is the
preset desired pressure plus or minus 0.1bar, to reduce power consumption.
(2) Variable Flow Control
Adopt inverter to drive the compressor can adjust the rotation speed of the motor in real time according to
the actual air compression. In case of high air consumption, the pressure remains unchanged, but the
speed compensates automatically to meet the supply needs. When the air consumption is low, pressure
is maintained constant and speed is automatically reduced to supply compressed air which is just enough.
(3) No Current Impact during Starting
The air compressor is started via invert. The maximum starting current is 1.2 times the rated current for
power frequency start. Hence, our variable speed air compressor exerts little impact on the grid during
starting. It enjoys reduced stress and consequently prolonged service life.
(4) High Economical Efficiency
Throughout the operating life of the air compressor, energy costs account for most of all costs. However,
by using VSD, energy consumption is reduced by 30%.Therefore, the energy cost saved by a variable
speed air compressor for three years is roughly equivalent to purchase price of the unit.
Life of compressor air end
Rotors are asymmetric in profile and backed up by ball bearings and roller bearings and operate at a low speed. Helical gears can produce axial force to kill some acting force, which reduces the load of the bearing of compressor air end. Thereby low in abrasion and maintenance and repair expenses and the compressor air end being long in service life.
More reliable operation
With frequency conversion soft start reduce in-rush starting current, reduce wear on electrical switch gears and motor windings. Also maintain less power during starting and stopping of motors and increase protection to motors. Also reduce peak demand and improve power factor.
Efficiency and energy conservation
Thanks to the variable-speed control technology, the capacity of compressors can be perfectly combined with the air use of users, which downright avoid the unloading power loss. In intermittent air use, the minimized load of soft start eliminates the starting frequency of the peak current and further smooth start can reduce the power supply, equipment costs as well as the impact on the network power.
In the case of rated power license setting desired pressure at discretion, and maintaining constant pressure at discretion, and maintaining constant pressure
User to choose any delivery pressure between 4-13bar without any gears or belt change. When the use of air increases the unit increases air output through automatic acceleration of rotational speed to avoid a falling pressure and ensure volume at constant pressure. When the use of air decreases, the unit reduces air output by automatically lowering the rotational speed to avoid pressure increase and ensure continued air supply constant pressure.
