DEVICE AND METHOD FOR MONITORING THE OPERATION OF AN HVAC SYSTEM, ASSEMBLY COMPRISING AN HVAC SYSTEM AND SUCH A MONITORING DEVICE, AND ASSOCIATED COMPUTER PROGRAM PRODUCT

摘要

This device (14) for monitoring the operation of an HVAC system (12) comprises first means (80) for acquiring values of measured quantities associated with the HVAC system, an estimation module (82), as a function of the values measured values and using a neural network, the value of at least one parameter representative of the operation of the HVAC system, each measured quantity being an input variable of the neural network and each representative parameter being an output variable of the neural network. The device (14) further includes a CVCA diagnostic module (86), wherein the diagnostic module (86) is configured to calculate CVCA fault probabilities using a Bayesian network, the defects being predefined, each input variable of the Bayesian network being associated with a respective representative parameter and each probability of a respective fault being an output variable of the Bayesian network.
