Core Concepts
Compressor-based machines offer rich time series data for fault detection, prediction, and forecasting, driving research in the field.
Abstract
Compressor-based machines are crucial in various sectors, including refrigeration, HVAC, and heat pumps.
IoT data collection enables proactive management and fault prediction in these machines.
The survey focuses on Fault Detection (FD), Fault Prediction (FP), Forecasting, and Change Point Detection (CPD).
Various algorithms and approaches are compared for each task, highlighting the importance of feature selection and model performance.
Challenges include dataset availability, feature extraction, and algorithm selection.
