Optimal operating condition interval and performance of chiller in district cooling system

Taking the performance characteristics of various types of large-scale chillers in district cooling system as the object, briefly discusses the main factors affecting the performance of the chiller. Based on the mearsured experimental performance data of different chillers, analyses the energy efficiency ratio of centrifugal chiller, flue gas, steam and hot water type lithium-bromide absorption water chillers in different operating conditions, and also gives out the optimal operating condition interval and the performance model formula for several types of large-scale chillers, which provide a theoretical basis for the optimal allocation and energy efficient operation of chillers.
