DYNAMIC SIMULATION AND OPTIMIZATION OF START-UP PROCESS OF PROPYLENE HEAT PUMP COMPRESSOR
In response to the problems of working condition fluctuations,frequent vibration,and high energy consumption during the start-up process of the propylene heat pump compressor,the working point variation curve of compressor was studied by establishing a dynamic simulation model in order to verify the rationality of start-up program.Based on dynamic simulation results and combined with actual situations,the problems in the existed start-up program were analyzed to provide theoretical support for the optimization of the start-up program.
