The use of exergetic skills to design a trigeneration system (CCHP) in a hotel complex in Xalapa, Veracruz

Abstract

In the present work developed as part of the professional intervention of the master’s degree in energy engineering, shows the use of exergetic skills, including some thermal software, and shows how, together, could demonstrate which alternative could be allows the modeling of a wide range of thermal systems such as combined gas turbine cycles, steam plants, power generation systems, cogeneration and a wide range of power plant system. A) The thermal and electrical consumptions of the hotel complex were determined. B) The selection of the possible components and the probabilities of accommodation in an energy staggering were made. C) The system was shown in a Thermal software. D).- Border and environmental conditions were established for the derate adjustment and the initial exergetic conditions. E) Thermodynamic modeling was performed. .F) Each step was validated by direct calculation, First Law Analysis of Thermodynamics, Second Law of Thermodynamics and Exergetic Analysis to determinate wich component has the higher exergetic destruction.Thermoeconomically when implementing the trigeneration system in the hotel complex and through a cash flow, it is necessary understood ,that the joint trigeneration project of the two hotels is economically viable where the return on investment is 6.51 years and from that year will begin To generate savings, the internal rate of return of 18% higher than the 12% that was taken as reference and the net present value of $ 6, 271,739.30
