Simulation Study of Thermal Performance of the Approximate Ericsson Cycle for Waste Heat Utilization
In order to improve the efficiency and quality of waste heat resources,an approximate Ericsson cycle is proposed in this paper.And EBSILON software is used to model and simulate the approximate Ericsson power cycle waste heat utilization system.Using the validated model,this paper separately investigates the effects of factors such as work mass flow rate,compressor efficiency,expander efficiency and heat source temperature on the cycle efficiency and waste heat utilization efficiency.The results show that the cycle efficiency is basically stable when the work mass flow rate is within a certain range.And after exceeding a certain value,the cycle efficiency decreases rapidly,while the waste heat utilisation efficiency continues to be improved;the increase of the compressor efficiency and expander efficiency can obviously improve the cycle efficiency and the waste heat utilization efficiency;the increase of the heat source temperature can improve the cycle efficiency,but it will lead to the decrease of the waste heat utilisation efficiency.The significant analysis of the influence of the factors on the cycle efficiency shows that the expander efficiency has the greatest influence on the cycle efficiency,and the work mass flow rate has the least influence.The research results provide a new way for waste heat utilisation,which can effectively improve the quality of energy utilisation and at the same time provide a reference for engineering applications.
