Faults happen. They can occur in unitary air-conditioning equipment and cause it to perform below its expected, rated or designed value, leaving owners/operators disappointed. Examples of faults include coil fouling, loss of refrigerant charge, excessive duct flow resistance, economizer faults, etc. This seminar shows results of recent groundbreaking research projects focusing on the effects of faults on unitary equipment, and presents new methods for modeling the effects of those faults. Attendees of the seminar will be prepared to account for these effects when designing, planning maintenance, or predicting building energy performance.
