چکیده

Variable refrigerant flow (VRF) systems faults are inevitable due to installation errors, degradation, and other reasons. It is of great value quantitatively understand the impact on VRF performance clarify changing trends variables under different types through experiments. In particular, experimental analysis simultaneous situations helpful improve fault detection diagnosis technology systems. There have been some previous studies faults, but none them concerns modern their faults. This paper presents results from a laboratory study system with provides first published combinations triple in addition previously untested double The quantitative three crucial parameters, e.g. cooling capacity, power, COP, has analyzed. addition, influence variation trend parameter during single summarized. Results show that outdoor fouling greatest impact, which can cause 47.6% COP drop 80.27% capacity reduction. variable superimposed offset, also dominant characteristic.
