Compressed air system audit is an essential element in improving the energy efficiency of industrial facilities. As part of the audit, a comprehensive testing and verification of system components are conducted. The audit aims to determine the correct operation of individual components, detect potential damages and leaks, and determine the extent of losses caused by them in the compressed air system, which delivers compressed air at pressure from the compressor to the devices.
The basic industrial components of a compressed air installation include compressors, compressed air treatment systems (comprising coolers, dryers, filters, separators), a pressure tank, and the network of pipelines used for air transport. During the audit, measurements of compressor performance, workload, air production quantity, power values, and equipment configurations are conducted. An important aspect of the audit is also the verification of air-tightness, which allows even the smallest defects to be detected. Additionally, spot measurements of compressed air pressure are taken at several key points in the installation.
The audit results are compiled into a report, which… includes measurements, a description of identified issues, and an estimate of the costs of corrective actions. This report serves as the basis for planning the optimization of compressor operation and improving the energy efficiency of the installation. It’s worth noting that a compressed air audit is not a standard examination, and each case requires an individual approach and adaptation to the specific characteristics of the installation and equipment.
