Belt Looseness Fault Simulation in an HVAC Testbed

This testbed focuses on simulating and diagnosing belt looseness in a belt-driven HVAC (Heating, Ventilation, and Air Conditioning) system. Current (R-, S-, T-phase; sampling rate=100kHz), Vibration (x-, y-axis; sampling rate=25.6kHz), RPM (motor, fan; sampling rate=100kHz) are included. Four different conditions are emulated (normal(d0), weak(d1), moderate(d2), strong(d3), critical(d4)). For more informations, please visit open-access journal "Data in Brief".
