Comparative experimental study of an open piston compressor working with R-1234yf, R-134a and R-290

Navarro-Peris, Emilio; Martínez Galván, Israel Octavio; Nohales Herraiz, Jesús Ángel; Gonzálvez Maciá, José (Elsevier, 2013-05)

Among the different alternatives proposed in the automotive field to replace R-134a and R-1234yf is a new generation fluid which has recently gained great importance for MAC (Mobile Air Conditioning) systems. This fluid ...
Drop-in energy performance evaluation of R1234yf and R1234ze(E) in a vapour compression system as R134a replacements

Mota-Babiloni, Adrián; Navarro-Esbrí, J.; Barragán Cervera, Ángel; Molés, Francisco; Peris, Bernardo (Elsevier, 2014)

[EN] This paper presents an energy performance evaluation of two low-GWP refrigerants, R1234yf and R1234ze(E), as drop-in replacements for R134a. Tests are carried out in a monitored vapor compression system combining ...
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 analysis of R1234yf as a drop-in replacement for R134a in a vapor compression system

Navarro Esbri, Joaquin; Mendoza Miranda, Juan Manuel; Mota Babiloni, Adrián; Barragán Cervera, Ángel; Belman Flores, Juan Manuel (Elsevier, 2013-05)

[EN] This paper presents an experimental analysis of a vapor compression system using R1234yf as a drop-in replacement for R134a. In this work, we compare the energy performance of both refrigerants, R134a and R1234yf, ...
Numerical Optimization of an Ejector for Waste Heat Recovery Used to Cool Down the Intake Air in an Internal Combustion Engine

Galindo, José; Gil, A.; Dolz, Vicente; Ponce-Mora, Alberto (American Society of Mechanical Engineers, 2020-10-01)

[EN] In the present paper, a numerical investigation of a jet-ejector is carried out using a real gas model of R1234yf. The prototype under investigation works with specific operating conditions of a jet-ejector refrigeration ...
Shell-and-tube evaporator model performance with different two-phase flow heat transfer correlations. Experimental analysis using R134a and R1234yf

Navarro-Esbrí, J.; Molés, Francisco; Peris, Bernardo; Barragan-Cervera, Angel; Mendoza-Miranda, Juan Manuel; Mota-Babiloni, Adrián; Belman Flores, Juan Manuel (Elsevier, 2014)

[EN] 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 ...
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 ...
