Drop-in analysis of an internal heat exchanger in a vapour compression system using R1234ze(E) and R450A as alternatives for R134a

Mota Babiloni, Adrián; Navarro Esbrí, Joaquín; Barragán Cervera, Ángel; Moles, F.; Peris, B. (Elsevier, 2015-10-15)

The IHX (internal heat exchanger) is introduced in some refrigeration systems in order to achieve higher energy performances. Results obtained vary greatly depending on the refrigerant used and working conditions. This ...
Evaluation of R448A and R450A as Low-GWP alternatives for R404A and R134a using a micro-fin tubes evaporator model

Mendoza Miranda, Juan Manuel; Mota-Babiloni, Adrián; Navarro Esbri, Joaquin (Elsevier, 2016-04-05)

[EN] When retrofitting new refrigerants in an existing vapour compression system, their adaptation to the heat exchangers is a major concern. R450A and R448A are commercial non-flammable mixtures with low GWP developed to ...
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 ...
