Algorithmic method for the opening rate of the on-off fan-coil unit water system

Based on the probability theory, defines three methods for computing the whole opening rate of the on-off fan-coil unit water system, including the actual survey method, the weighted mean method and the binomial distribution method. After the comparative analysis, obtains the variation range of the opening rates: that of the first method is equal to the second one but less than the third one. Because the binomial distribution method does not need to calculate the opening rate of each fan-coil unit at every moment in the actual application, it is a preferable choice.
