Analysis based on EU Regulation No 517/2014 of new HFC/HFO mixtures as alternatives of high GWP refrigerants in refrigeration and HVAC systems

Mota Babiloni, Adrián; Navarro Esbri, Joaquin; Barragán Cervera, Ángel; Molés Ribera, Francisco; Peris Pérez, Bernardo (Elsevier, 2015-04)

[EN] The EU Regulation No 517/2014 is going to phase-out most of the refrigerants commonly used in refrigeration and air conditioning systems (R134a, R404A and R410A) because of their extended use and their high GWP values. ...
Effect of mean void fraction correlations on a shell-and-tube evaporator dynamic model performance

Navarro-Esbrí, J.; Milián Sánchez, Víctor; Mota Babiloni, Adrián; Molés Ribera, Francisco; Verdú Martín, Gumersindo Jesús (Taylor & Francis, 2015-10-03)

In this paper, the influence of different mean void fraction correlations on a shell-and-tube evaporator dynamic model performance has been evaluated. The model proposed is based on the moving boundary approach and includes ...
Evaluación energética de los refrigerantes R1234yf y R152a como alternativa al R134a en sistemas de refrigeración

Mendoza Miranda, Juan Manuel; Navarro Esbri, Joaquin; Mota Babiloni, Adrián; Belman Flores, Juan Manuel; Rubio Arana, José Cuauhtémoc; Peris Pérez, Bernardo; Molés Ribera, Francisco (Universidad Nacional de Educación a Distancia (UNED), 2013-10)

[EN] This paper presents a theoretical performance of R1234yf and R152a as possible replacements of R134a in refrigeration systems. The refrigeration system performance using R134a, R1234yf and R152a was carried out for ...
Experimental characterization of an ORC (organic Rankine cycle) for power and CHP (combined heat and power) applications from low grade heat sources

Peris Pérez, Bernardo; Navarro Esbri, Joaquin; Molés Ribera, Francisco; González, Manuel; Mota Babiloni, Adrián (Elsevier, 2015-03)

An ORC (organic Rankine cycle) module, designed and built for a specific CHP (combined heat and power)) application, is tested in this paper. The aim of the work is to characterize the system performance in the operating ...
Theoretical energy performance evaluation of different single stage vapour compression refrigeration configurations using R1234yf and R1234ze(E) as working fluids

Molés Ribera, Francisco; Navarro Esbri, Joaquin; Peris Pérez, Bernardo; Mota Babiloni, Adrián; Barragán Cervera, Ángel (Elsevier, 2014-08)

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 ...
