Thermo-Economic Analysis of Triple Production System, Combination with Solid Oxide Fuel Cell and Absorption Chiller

This article introduces and analyzes the thermodynamic and economic performance of two triple hybrid systems that generate power, thermal and refrigeration energy. The primary drive is a hybrid cycle consisting of a gas turbine and solid oxide fuel cell, supplemented by single-effect and double-effect absorption chillers as the secondary drive. Given the significance of the fuel cells in this system, detailed thermodynamic and thermal and electrochemical analyses have been conducted to ensure accurate calculations. The study examines that the impact of the 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%.
