Optimized chiller unit configuration based on all-year dynamic cooling load

Proposes a method for selecting optimal chiller unit configuration in design phase, in which the energy consumption of chillers is simplified  to the function of actual cooling capacity and entering water temperature of the condenser, then the all-year building load frequency distribution under different outdoor wet-bulb temperature that determines the minimum entering cooling water temperature is obtained by dynamic load calculation, and finally, calculates the all-year energy consumption and energy consumption under different building load demand based on different chiller unit configurations, accordingly obtaining the optimal chiller unit configuration.
