The Energy Consumption Calculation of the Fan Coil Chilled Water System Based on Variable Chilled Water Temperature and Flux

The article builds up the mathematics model about the fan coil chilled water system energy consumption. By the model, it calculates the energy consumption under the different flux ratio, the result shows that the optimal water parameter is different from the design parameter, it has relation with the chilled water pump head. When the pump head value is larger, adopting the smaller design flux’s parameter; when the pump head value is smaller, adopting the larger design flux’s parameter. So to make the energy consumption minimum, the water parameter should be computered.
