Performance evaluation of an Organic Rankine Cycle (ORC) for power applications from low grade heat sources
Peris, Bernardo; Navarro-Esbrí, Joaquín; Moles, Fran; Martí, José Pascual; Mota-Babiloni, Adrián Elsevier (2015-01-22)In this paper the performance of an Organic Rankine Cycle (ORC) module, which was designed and built for a specific power application, is experimentally characterized. The ORC tested satisfies the main specifications for ... -
Shell-and-tube evaporator model performance with different two-phase flow heat transfer correlations. Experimental analysis using R134a and R1234yf
Navarro-Esbrí, Joaquín; Moles, Fran; Peris, Bernardo; Barragán Cervera, Angel; Mendoza-Miranda, Juan Manuel; Mota-Babiloni, Adrián; Belman, Juan Elsevier (2014-01)This work presents a model of a shell-and-tube evaporator using R1234yf and R134a as working fluids. The model uses the effectiveness-NTU method to predict the evaporation pressure and the refrigerant and secondary fluid ... -
Theoretical comparison of low GWP alternatives for different refrigeration configurations taking R404A as baseline
Mota-Babiloni, Adrián; Navarro-Esbrí, Joaquín; Barragán Cervera, Angel; Molés Ribera, Francisco; Peris, Bernardo Elsevier (2014-04-25)Six refrigerants are evaluated as low GWP replacements for R404A using different configurations, including two-stage system architectures. These refrigerants are selected according to similar characteristics to R404A, and ... -
Theoretical energy performance evaluation of different single stage vapour compression refrigeration configurations using R1234yf and R1234ze(E) as working fluids
Molés, Francisco; Navarro-Esbrí, Joaquín; Peris, Bernardo; Mota-Babiloni, Adrián; Barragán Cervera, Angel Elsevier (2014-05-10)R1234yf and R1234ze(E) have been proposed as alternatives for R134a in order to work with low GWP refrigerants, but this replacement results generally in a decrease of the performance. For this reason, it is interesting ... -
Thermo-economic optimization of small-scale Organic Rankine Cycle: A case study for low-grade industrial waste heat recovery
Peris, Bernardo; Navarro-Esbrí, Joaquín; Mateu-Royo, Carlos; Mota-Babiloni, Adrián; Molés, Francisco; Gutierrez Trashorras, Antonio J.; Amat-Albuixech, Marta Elsevier (2020-10-01)This work is focused on a case study of a small-scale Organic Rankine Cycle (ORC) adopted for electricity production from low-grade industrial waste heat recovery. This kind of applications raises a great interest due to ... -
Thermodynamic analysis of a combined organic Rankine cycle and vapor compression cycle system activated with low temperature heat sources using low GWP fluids
Moles, Fran; Navarro-Esbrí, Joaquín; Peris, Bernardo; Mota-Babiloni, Adrián; Kontomaris, Konstantinos Elsevier (2015-08-05)A combined organic Rankine cycle and vapor compression cycle (ORC–VCC) system activated by low temperature heat sources was studied. Two low GWP fluids were considered as working fluids for the VCC and two different low ...
