新型跨临界CO2循环冷热电联供系统分析
Analysis of a novel trans-critical CO2 cycle Combined Cooling,Heating and Power system
摘要
Abstract
The Combined Cooling Heating and Power(CCHP)system boasts high energy conversion efficiency and exhibits clear advantages in harnessing medium to low temperature heat sources.In our study,we propose a Trans-Critical CO2 CCHP system composed of a Rankine cycle and an Ejector Refrigeration cycle,and analyze the thermodynamic performance of this CCHP system.The system is optimized based on the objective functions of maximum net output power and cooling capacity(in CCP mode),or maximum net output power and heating capacity(in CHP mode).Our findings indicate that within the range of the studied parameters,the system has an optimal net power output,and its cooling and heating capacities can be adjusted.These results carry great significance for the utilization of waste heat at medium to low temperatures.关键词
