Book excerpt: Air compressors are a significant industrial energy user and therefore a prime target for industrial energy audits. The project goals were to develop a software tool, AIRMaster, develop a methodology for performing compressed air system audits, and conduct field audits to refine the methodology and assess savings potential from six common Operation and Maintenance (O & M) measures. AIRMaster and supporting manuals are designed for general auditors or plant personnel to evaluate compressed air system operation with simple instrumentation during a short-term audit. AIRMaster provides a systematic approach to compressed air system audits, analyzing collected data, and reporting results. AIRMaster focuses on inexpensive Operation and Maintenance measures, such as fixing air leaks and improving controls, that can significantly improve performance and reliability of the compressed air system, without significant risk to production. An experienced auditor can perform an audit, analyze collected data, and produce results in 2-3 days. AIRMaster reduces the cost of an audit, thus freeing funds to implement recommendations. AIRMaster proved to be a fast and effective tool. In seven audits AIRMaster identified energy savings of 4,056,000 kWh, or 49.2% of annual compressor energy use, for a cost savings of $152,000. Total implementation costs were $94,700 for a project payback period of 0.6 years. Available airflow increased between 11% and 51% of plant compressor capacity.
