Cooperative variable flow control strategy for central air conditioning water system

Sets up a quinary quadratic regression model between total energy efficiency ratio and cooling load ratio, outdoor dry bulb temperature, air volume of cooling tower fan, cooling water flow rate, chilled water flow rate of central air conditioning water system by using the response surface methodology, obtains the corresponding air volume of the fan, chilled water flow rate and cooling water flow rate to the highest total energy efficiency ratio of the cooling system while load rate and dry bulb temperature changing, then obtains the power adjustment programs of cooling tower fans, cooling water pumps, chilled water pumps and chillers. The results show that cooperative variable flow control can effectively improve the total energy efficiency of the air conditioning system.
