Abstract

The electrogasdynamic (EGD) generator is incorporated with one ejector refrigeration system to produce cooling, heating and power effects together. The performance of the combined cycle is comprehensively evaluated based on the first and second laws of thermodynamics. The thermodynamic analyses focus on the influence behaviors of the electrical current, the mass flow rate of the primary fluid, the operating temperatures on the system performance parameters. The key factors are further identified to effectively improve the system performance. It is found the combined cycle has the more desirable exergy and energy utilization efficiencies. The entrainment ratio is an underlying factor changing the system performance. The mixing process and the evaporating process are needed to be further improved for the more excellent combined cycle based on the eletrogasdynamic generator.
