Abstract

This article introduces and analyzes the thermodynamic and economic performance of two triple hybrid systems that generate power, thermal, and refrigeration energy. The primary innovations of this research are the implementation of single-effect and double-effect absorption chillers downstream of the system and the use of a repetition algorithm to analyze and compare the performance of the two systems. given the significance of fuel cells in this system, detailed thermodynamic, thermal, and electrochemical analyses have been conducted to ensure accurate calculations. The study examines the impact of compressor pressure ratio and air-to-fuel ratio on energy and exergy efficiency, exergy destruction and exergy loss rates, system costs, and heating and cooling production. Results indicate that increasing the compressor pressure ratio enhances electrical and exergy efficiency system while reducing exergy destruction rates and electricity costs. Additionally, switching from a single-effect to a double-effect absorption chiller reduces exergy destruction by 5.4% but increases electricity production costs by 28%.
