Climate change is demonstrated through global surface temperatures increase in the last
century. To stop this phenomenon, new regulations that ban or tax greenhouse gas fluids …

The use of vapor compression system-based air-conditioning units is predominant in
conventional fossil-fueled and electric vehicles. Mobile air-conditioning (MAC) units play a …

Due to the entry into force in 2014 of the European F-Gas Regulation n° 517/2014 and the
subsequent Kigali amendment, the phase-out of the medium and high-GWP refrigerants has …

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 …

In this paper we present two different analyses of R1234yf and R1234ze (E) as drop-in
replacements for R134a in a small power refrigeration system. The first analysis is based on …

The global implementation of the Montreal Protocol has accelerated research in the last
decade to develop low GWP refrigerants, and numerous low GWP refrigerants have been …

The latest international regulations on the reduction of greenhouse gases are strongly
redesigning the scenario of use of refrigerants, gradually eliminating the possibility of …

R1234yf has been considered as an alternative refrigerant with the low global warming
potential (GWP), but it is flammable. Therefore, it is necessary to study the reduction or …

This paper presents an energy and exergy analysis of a domestic refrigeration system using
R1234yf as a drop-in replacement for R134a. We base our analysis on a series of …

This paper presents an experimental study of the R1234yf drop-in performance in an R134a
small power vapor-compression refrigeration system. Experiments were performed for two …
