Large-scale heat pumps can contribute towards the decarbonisation of district heating
systems and industrial processes. Unidentified faults can have a negative impact on the …

Variable-speed packaged rooftop units have been increasingly adopted in the commercial
sector in the last decade. Several studies, mainly focused on constant-speed rooftop units …

Faults and malfunctions occurring in engineering systems may cause additional resources
consumptions and economic expenditures, thus their detection and isolation is of great …

The purpose of this paper is to apply thermoeconomics in a HVAC&R facility in order to
implement the dynamic behaviour as well as to solve the direct problem of diagnosis. New …

Concerning the building environment HVAC facilities, even if a great effort has been made in
developing components and systems with high nominal efficiencies, less attention has been …

In order to investigate options for improving the maintenance protocol of commercial
refrigeration plants, two thermoeconomic diagnosis methods were evaluated on a state-of …

In order to improve the accuracy of gas-path fault detection and isolation for a marine three-
shaft gas turbine, a gas-path fault diagnosis method based on exergy loss and a …

When a malfunction occurs in a marine gas turbine, its thermal efficiency will decrease
slightly, and the gas path fault is often difficult to distinguish. In order to solve this problem …
