Control Strategies For Air Compression System
Performance and overall efficiency improvement of Air Compressor system performance needs the detail attention to each of its components and it is necessary to examine both the supply and demand sides of the system and how they interact, particularly during times of peak demand.

Supply And Demand
System dynamics (changes in demand over time) are particularly significant in compressed air systems. A efficient Air Compression system relies on the use of controls, storage, and demand management to properly design a system that fulfils peak requirements while still operating effectively at part-load. The lack of coordinated compressor controls in many systems can cause compressors to operate in conflict with one another, short cycle, or blow off, all of which are indicators of inefficient system operation.
Manufacturers of compressors have created a variety of various control systems over the years. When the need for air decreases, controls like load/unload and start/stop turn the compressor off or unload it to stop the Supply of the Air. By adjusting the inlet and multi-stage control, the compressor can operate at part load and deliver less air when demand is low. In non – peak hours, the compressor’s speed is decreased with variable speed controllers. Part-load compressors typically operate at a lower efficiency than full-load compressors.
Control System with Multiple Air Compressors
For efficient compressor operation and air delivery to the system, numerous compressors need far more sophisticated controls. Network controls make decisions to stop/start, load/unload, modulate, and adjust displacement and speed through a chain of communication involving the on-board microprocessors and microcontroller based Air Compression System . Typically, one compressor takes on the lead position, with the rest following its instructions.
The functions required to coordinate compressed air as a utility, optimally are controlled by system master controls. The capacity to monitor and regulate all system components along with trends to improve maintenance procedures and lower operating costs are just a few of the many functional features of system master controls. The majority of multiple compressor controls maintain the optimum number of compressors at full load while trimming (running at part load) one compressor to balance supply and demand.
Flow and Pressure Controllers
Along with single and multiple Compressed Air System Controls mentioned above, the pressure/flow controllers (P/FC) which are system pressure controls can operate in coordination. A P/FC is a device that separates the supply side from the demand side of a compressor system and uses storage. Intermittent loads, which can have an impact on system reliability and system pressure, can be addressed via controlled storage. The major plant distribution system should receive compressed air at the lowest steady pressure possible, and compressed air that has been stored should be used as much as possible to support transient events. In general, maintaining stable system pressure with a highly fluctuating demand load will require a more complex control technique than doing so with a constant, steady demand load.
