Availability Performances of Ground-Coupled Heat Pump Systems

Abstract

The paper presents aspects regarding the reliability and availability of ground-coupled heat pump systems (GCHP). Basic concepts of predictive reliability are introduced and the two modes of reliability analyses (quantitative and qualitative) are shown specifically for PCSS. In order to be able to model the availability of GCHP systems, global reliability indicators must be determined. Furthermore, failure manners and their effects on system reliability, as well as the graphical-analytical methods that could be applied to GCHP systems are analyzed. Finally, a case study for the experimental system installed in Thermodynamics Laboratory belonging to Energy Engineering Faculty is shown
