Résumé

This paper identifies important faults and their performance impacts for rooftop air conditioners. The frequencies of occurrence and the relative costs of service for different faults were estimated through analysis of service records. Several of the important and difficult to diagnose refrigeration cycle faults were simulated in the laboratory. Also, the impacts on several performance indices were quantified through transient testing for a range of conditions and fault levels. The average impacts of the faults on cooling capacity and coefficient of performance were also evaluated. Based upon the results, all of the faults are significant at the levels introduced, and should be detected and diagnosed by a fault detection and diagnostics system.
