An Evaluation of HVAC Failure and Maintenance Equipment Data for Facility Resiliency and Reliability

摘要

This paper presents a slice of an enormous facility equipment database containing failure and maintenance information for more than 100,000 power, mechanical, and electronic components. Motivated by a vested interest in the resilience of critical infrastructure, the U.S. Army Corps of Engineers collected the data. Heating, ventilating, and air-conditioning (HVAC) equipment is well represented in the database-some 13,000 unit-years of information describe the reliability and maintenance activity of over 1600 air-handling units and condensers. The analysis of this equipment sheds light on failures that are inherent to the design of equipment and those that can be influenced by preventative maintenance. These fascinating and often counterintuitive relationships between equipment maintenance and failure rates may change the application of reliability-centered maintenance.
