Screw Chillers Model Suitable for Variable Operating Condition

摘要：

For predict the performance of screw chillers working at variable operating conditions, a simulation model based on TRNSYS was presented. Based on the primary physics,fluid and heat transfer theory, the sonmodels including the compressor, shell and tube condenser, and f looded evaporator were present.Taken TRNSYS as the simulation platform, a simulation of a chillers was completed. Compared the prediction and experimental value, the errors are within ±8％.The results show that the model has high accuracy and are suitable for simulation at part-load.
