Simulation of operating conditions and working fluids for organic Rankine cycles
Operating conditions for different fluids in Organic Rankine Cycles using low grade energies were compared. The following fluids were used: R152a (1,1-difluroethane), R-290 (propane), R-600a (2-methylpropane or isobutane), R-744 (CO2) y R-1270 (propylene). Simulation with HYSYS v3.2 was used to supp...

| description |
Operating conditions for different fluids in Organic Rankine Cycles using low grade energies were compared. The following fluids were used: R152a (1,1-difluroethane), R-290 (propane), R-600a (2-methylpropane or isobutane), R-744 (CO2) y R-1270 (propylene). Simulation with HYSYS v3.2 was used to support the research. Organic Rankine cycle was studied. Also, the following modifications were studied: reheating, regeneration and reheating-regeneration. Regeneration cycle showed the best results, however, thermal efficiencies were lower than 10%. Operating conditions were simulated in order to increase this value. It was determined that the fluid that presented the best behavior was the R-600a refrigerant, using a Rankine with regeneration cycle operating between 3 500 kPa and 150 ºC at the turbine entrance and 700 kPa in the condenser. A thermal efficiency of 15.33 % was obtained and 7.11 kW of electric power can be produced. |

Los fluidos estudiados fueron: R152a (1,1-difluroetano), R-290 (propano), R-600a (2-metilpropano o isobutano), R-744 (dióxido de carbono), y R-1270 (propileno). Se realizó la simulación del ciclo de Rankine orgánico y de sus modificaciones: ciclo con recalentamiento intermedio, ciclo de regeneración y ciclo con recalentamiento y regeneración. Se usó el simulador de procesos HYSYS v3.2. Los mejores resultados se alcanzaron para el ciclo con regeneración, aunque los rendimientos térmicos fueron inferiores al 10%. Se simularon condiciones de operación que permitieran superar este valor, lo cual se logró con el refrigerante R-600a en el ciclo Rankine con regeneración, que opere entre 3 500 kPa y 150 ºC a la entrada de la turbina, y 700 kPa en el condensador. Con ello se obtiene un rendimiento térmico de 15,33% y se producen 7,11 kW de potencia eléctrica.application/pdftext/xmlspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/investigacion_duitama/article/view/10213/9004https://revistas.uptc.edu.co/index.php/investigacion_duitama/article/view/10213/11227Derechos de autor 2020 REVISTA DE INVESTIGACIÓN, DESARROLLO E INNOVACIÓNinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Revista de Investigación, Desarrollo e Innovación; Vol. 10 No. 2 (2020): Enero-Junio; 349-358Revista de Investigación, Desarrollo e Innovación; Vol. 10 Núm. 2 (2020): Enero-Junio; 349-3582389-94172027-8306Power cycleOrganic Rankine cycleOrganic fluidsProcess simulationCiclos de potenciaCiclo Rankine orgánicoFluidos orgánicosSimulador de procesosSimulation of operating conditions and working fluids for organic Rankine cyclesSimulación de condiciones de operación y fluidos de trabajo para ciclos Rankine orgánicosArtículo de revistahttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTexthttps://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85Hernández Fernández, Nerio JoséZumalacárregui de Cárdenas, LourdesPérez Ones, OsneyPublicationORIGINAL9004.htmltext/html44460https://repositorio.uptc.edu.co/bitstreams/7e9bbc7b-d651-40f2-baa7-43664ab17c6b/downloadda4e3dcc0e5e4510cd58eb682e6fb70cMD51trueAnonymousREAD11227.htmltext/html43940https://repositorio.uptc.edu.co/bitstreams/9c95470f-f4a3-4af2-86c3-80ae0a6faedf/download17820885f9ab2254b4a64019230c0b36MD52falseAnonymousREADTEXT9004.html.txt9004.html.txtExtracted texttext/plain7828https://repositorio.uptc.edu.co/bitstreams/b7f3ca07-55d3-4c31-b8c8-2d82b30f18ef/download5cefed57935a892864724ac482aed839MD53falseAnonymousREAD11227.html.txt11227.html.txtExtracted texttext/plain7537https://repositorio.uptc.edu.co/bitstreams/09704f7d-d349-46d6-be9b-2de04d1776a0/download7aa82e21dcd68a188afe544deb53f806MD54falseAnonymousREAD001/10318oai:repositorio.uptc.edu.co:001/103182026-10-29 18:05:42.069open.accesshttps://repositorio.uptc.edu.coRepositorio Institucional UPTCbdigital@metabiblioteca.com |
