The identification of the resistance characteristics of the pipe network in the air conditioning water system is a necessary condition for establishing an accurate and reliable pipe network simulation model,and it is also a very complex nonlinear function optimization problem.This paper proposes a method for identifying the resistance characteristics of the air conditioning water system based on the cuckoo search algorithm,which is based on the measured data under various operating conditions of the pipe network system,uses the cuckoo search algorithm to solve the objective function of the resistance characteristics of the pipe network,and has higher identification accuracy.The case study shows that the flow error of each end of the pipe network simulation model calibrated based on this method is within 3%,and the identification results can meet the needs of engineering applications.
