Abstract
A monitoring method to monitor efficiency of air-blowing devices in a ventilation system. First, an optimal system curve is provided. Then, the air-blowing devices are activated with a first current frequency to obtain a first fan performance curve of the air-blowing devices according to the first current frequency and a test record. Next, first flow rates of the air-blowing devices are detected, and first system curves and efficiencies of the air-blowing devices are obtained by comparing the first flow rates with the first fan performance curve.
