ANALYSIS OF LOW GLOBAL WARMING POTENTIAL FLUORIDE WORKING FLUIDS IN VAPOUR COMPRESSION SYSTEMS. EXPERIMENTAL EVALUATION OF COMMERCIAL REFRIGERATION ALTERNATIVES

Mota Babiloni, Adrián (Universitat Politècnica de València, 2016-04-18)

[EN] Climate change is one of the short term threats for the humanity because it can affect seriously to the environment and, consequently, to vegetal and animal life. If it is not stopped in next years, maybe this effect ...
Comparative study of the performance of a heat pump for heating with R410A and R32 as refrigerant, using the software IMST-ART

Sánchez-Moreno-Giner, Luis; López-Juárez, Emilio; Gonzálvez-Maciá, José (Universidad de Castilla-La Mancha José Antonio Almendros Ibáñez, 2019-06-14)

[EN] According to the European Commission, at this moment, heating and cooling in buildings account for half of the energy consumption, while only a 16% of the energy used in this issue is obtained employing renewable ...
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 ...
Estudio de emisiones, combustión y rendimiento de un motor de camión dual-fuel con e-diesel y gasolina

Rebollar López, Nicolás (Universitat Politècnica de València, 2024-09-04)

[ES] Los métodos de combustión alternativos buscan mejorar problemas presentes en los métodos convencionales. El método dual-mode dual-fuel (DMDF), desarrollado en el instituto CMT, se centra en la reducción de emisiones ...
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, ...
Experimental evaluation of HCFC-22 replacement by the drop-in fluids HFC-422A and HFC-417B for low temperature refrigeration applications

Llopis, R.; Cabello, R.; Sanchez, D.; Torrella Alcaraz, Enrique; Patino, J.; Sanchez, J. G. (Elsevier, 2011-05)

The Regulation CE-1005/2009 has banned the use of virgin HCFC-22 in Europe from the 31st December 2009, because it contains chlorine, although its use is allowed up to the 31st December 2014 if it is recycled. Now, ...
Experimental evaluation of R448A as R404A lower-GWP alternative in refrigeration systems

Mota Babiloni, Adrián; Navarro Esbrí, Joaquín; Peris, Bernardo; Moles, Francisco; Verdú Martín, Gumersindo Jesús (Elsevier, 2015-11-15)

Due to the adoption of EU Regulation No 517/2014, R404A is going to be banned in Europe in most of refrigeration applications, in which is typically used, due to its very high GWP value, 3943. In this paper an experimental ...
Experimental study of an R1234ze(E)/R134a mixture (R450A) as R134a replacement

Mota Babiloni, Adrián; Navarro Esbri, Joaquin; Barragán Cervera, Ángel; Moles Ribera, Francisco; Peris Pérez, Bernardo (Elsevier, 2015-03)

[EN] This work presents an experimental analysis of a non-flammable R1234ze(E)/R134a mixture (R450A) as R134a drop-in replacement. While R134a has a high GWP value (1430), the R450A GWP is only 547. The experimental tests ...
HCFC-22 replacement with drop-in and retrofit HFC refrigerants in a two-stage refrigeration plant for low temperature

Llopis, R.; Torrella Alcaraz, Enrique; Cabello, R.; Sanchez, D. (ELSEVIER SCI LTD, 2012)

[EN] The world community has committed to eliminate the HCFC-22 refrigerant to a series of deadlines according to the agreements taken during the 19th Montreal Protocol meeting in September 2007. This phase-out, which is ...
On-site study of HCFC-22 substitution for HFC non-azeotropic blends (R417A, R422D) on a water chiller of a centralized HVAC system

Torrella Alcaraz, Enrique; Cabello, R.; Sanchez, D.; Larumbe, J.A.; Llopis, R. (Elsevier, 2010)

[EN] The European Regulation no 2037/2000 has banned manufacturing HCFC refrigerants from January 1st 2010, although its use is allowed up to 2015 if the fluids come from a recycling process. This situation creates the ...
