- Reduce compressor operation due to unnecessary pressure fluctuations. Appropriate loading, unloading, and stopping of compressors.
- Use of PID control. Reduction of set pressure is possible due to an increase in pressure stability.
To cut energy use by compressors, is it enough to control the number of compressors and to use inverter drives?
* Figures are for operation of four 150-kW compressors on weekdays (260 days x 20 hours)
and one on weekends (100 days x 10 hours).
From the viewpoint of energy savings, there is always some waste somewhere. But I don't know where the energy is being wasted...
Usually, when the number of compressors is controlled,
|It's a case of playing catch-up, such as when compressors are started/stopped after pressure has already reached a maximum/minimum point.||Pressure fluctuation occurs.|
|It's a case of automatic starting/stopping at a scheduled time or in a predetermined order.||Not so effective if device capacity or compression methods differ|
Usually these measures don't work as well as you expect.
You can reduce waste by roughly 10%!
With all this improvement, I want to know how much energy we're saving.
ENEOPT™comp compressor optimization control ensures supply of the right amount of compressed air for production.
Example of pressure control improvement by PID control
Energy savings that match the production schedule
- Operation automatically matches the production schedule for weekdays, holidays, and production start time. In addition to compressor operating status (load/unload/off), settings for pressure, wait time between unloading and shutdown, etc. can also be scheduled.
Increased efficiency by using a device with good load adjustment efficiency as the capacity controller
Ability to monitor power usage, CO2 emissions, and air unit consumption rate to quickly determine the actual energy savings and efficiency.
Energy efficiency by individually supplying the necessary amount of air to each system
Control of air-pressure reduction with ENEOPTairdep
The supply air pressure for each production line is controlled by adjusting the pressure from the air compressor.
