The effects show that the standard temperature inside the area with the anomaly was higher than 26 °C, although average temperatures within the comparison rooms have been between 22 °C and twenty five °C. An Investigation with the FCU´s Procedure confirmed the unit ran extended plus much more intensely in the home Along with the anomaly than in the opposite rooms, without giving relaxed circumstances, suggesting a malfunction of your system. It absolutely was also observed that the desired problems were being achieved in the in comparison rooms. The exact same basic principle was placed on detect faults in other rooms. Even though the design can detect anomalies Along with the implemented detection algorithm, even more assessments and diagnostics should be carried out to confirm faults and come across their genuine causes.
