摘要

This device (14) for monitoring the operation of a system hvac (12) comprises first means (80) of the acquisition of the values of the measured magnitudes associated with the system hvac, a module (82) of estimation, as a function of the values acquired of the measured values and with the aid of a neural network, the value of at least one parameter representative of the operation of the system hvac, each magnitude measured being a variable input of the neural network, and each being a variable parameter representative of the output of the neural network. The device (14) also comprises a module (86) of diagnosis of the system hvac, the diagnostic module (86) being configured to calculate the probability of defects of the system hvac with the aid of a network bayesian, the defects are predefined, each input variable of the network bayesian being associated with a parameter representative of the corresponding and each of the probability of a fault being a respective output of the network bayesian.
