A view of the entire system
Before compressed air can be used it must be generated, purified and distributed up to the respective application. Compressed air is a valuable form of energy. Nevertheless, too little is often done in order to lay out the overall system efficiently. Consumption is rarely measured or monitored. The cost situation is usually unclear.
This is where the Air Control System AirCS® comes in. The important aspects of making compressed air available and distributing it are examined within the framework of the AirCS® training project with regard to energy efficiency.
The AirCS® EduTrainer® serves as a basis to this end. It’s incorporated between compressed air generation (compressor) and the process. In combination with FluidLab®-AirCS® software, integrated measuring technology allows for innovative condition monitoring for the measurement of compressed air and energy consumption.
Generation and load management
The index number of the connected compressor is ascertained under the Condition Monitoring menu item. Various compressors can be compared and changes can be detected at an early stage. A calculation tool assists the user in ascertaining overall variable and fixed costs for compressed air generation.
In the case of load management, energy consumption is visualised for the compressor and an additional consuming device. Pressure thresholds are specified for switching the compressor on and off. In consideration of peak loads, the fundamentals of load management can then be imparted and tested.
As a prerequisite for the use of AirCS®, a system must be available for measurement, for example the MPS® distributing station or the equipment set TP 201 (basic level electro-pneumatics).
Distribution and monitoring
Long-term monitoring makes it possible to visualise consumption for individual applications. This allows for well-founded statements regarding energy costs. Targeted and actual statuses can be compared, for example in order to be able to detect and evaluate leaks.
Compressed air distribution components can be examined in the Flow Resistance menu. In this way, for example, the various resistances of different tubing lengths and diameters can be acquired and compared, as well as for T-connectors and elbow connectors. Furthermore, a calculation tool is available for determining the ideal pipe cross-section.
In the case of nominal flow measurement, a second, external pressure sensor can be used to ascertain the nominal flow rates of devices and components, in a manner similar to the ISO 6358 standard.

The FluidLab®-AirCS® software is an important component of the AirCS® equipment set. Just a few simple steps are needed to configure the interface and select the user language (German/English). Then the exercises can be started.
Exercises are supported by connection diagrams, descriptions and sample solutions taken from the AirCS® workbook. The measurement process is software-controlled. Results can be measured with measuring points, printed out or exported to a spreadsheet program. The software scope also includes the complete book of exercises in PDF format.
