摘要
Abstract
This paper establishes a simplified mathematical model for the variable frequency system of the primary pump in air conditioning chilled water systems using circuit simulation method.The parameters of the variable frequency system of the primary pump in air conditioning chilled water systems are calculated through this mathematical model.When the system adds or reduces the number of the chillers and the pumps,it compares the set differential pressure with the product of the resistance coefficient on the user side and the square of the minimum allowable flow rate of the system to determine whether the bypass valve should be opened.When multiple chillers operate simultaneously,in extreme cases,the designed bypass flow rate of the bypass pipeline is insufficient.关键词
