Self-checking method of sensors in chiller plants based on energy conservation with BMS monitoring data

Focusing on temperature sensors and flow rate sensors which have great influence on the analysis of energy performance of chiller plants, through the analysis of the physical and conservation relationships between the typical equipment and systems of the chiller plant, proposes an accurate self-checking method of sensors based on BMS monitoring data. With this method, the accuracy of sensors can be checked timely and the historical data can be amended. Taking an actual project as an example, corrects the deviation of historical data by this method, and analyses the actual operation performance of the system, and verifies the actual application effect of the method.
