Packaged rooftop units (RTUs) condition 69% of cooled commercial floor space in the U.S., and 60% of U.S. homes use central air-conditioning equipment, yet many of these systems are poorly operated and maintained. Fault detection and diagnostics (FDD) and new control approaches provide means to improve operations and transform how maintenance is performed. Recent activities are linking control of air conditioners and other equipment, integrating requirements for FDD into energy codes, developing standard laboratory test methods to support such requirements, and developing and field testing FDD methods for residential and commercial units. This seminar provides the latest on these developments.
