Supplementary material - Selection of relevant features to detect and diagnose single and multiple simultaneous soft faults in air-source heat pumps

This data is from an air-source heat pump model developed to introduce the impact of single and double simultaneous faults and obtain detailed system performance. These faults are Refrigerant Undercharge (UC), Refrigerant Overcharge (OC), Evaporator Fouling (EF), Condenser Fouling (CF), and Compressor Valve Leakages or reversing valve leakages (CVL). The provided data includes the contour plots of different system variables or features with double soft faults at three studied conditions. It also contains the data from the simulations from which the plots were created.
