Abstract

Based on the laws of thermodynamics and the principle of cascade energy utilization

a novel combined cooling heating and power(CCHP)system consisting of compressed air energy storage(CAES)technology and combustion engine is proposed to explore the strategy for efficient renewable energy application. The thermodynamic model of the system is established and the thermodynamic properties of the system are analyzed with a newly developed code. The thermodynamic analysis focuses on the performance of major equipment

including compressor

heat exchangers

turbine expander

and combustion engine. And the effects of key parameters such as the inlet pressure and temperature of turbine expander and the pressure ratio of compressor on the system performance are emphatically discussed. The simulation indicates that this system has higher value of both energy efficiency and exergy efficiency where system turbine expander

combustion engine and heat exchangers serve as the crucial roles. The energy efficiency

exergy efficiency and electricity conversion efficiency increase with the rising efficiency of system equipment

especially with the rising combustion engine efficiency.
