Performance of Automotive Air Conditioning System with R134a and R1234yf

International Journal of Air-Conditioning and Refrigeration, 2020
A steady-state mathematical model of a small-capacity Automotive Air Conditioning System (AACS) working with the refrigerants R134a (1,1,1,2-tetrafluoroethane) and R1234yf (2,3,3,3-tetrafluoropropene) is developed. The model considers the major components of the system, namely, the swash plate compressor with fixed stroke, thermostatic expansion valve (

Techno‐Economic Analysis of Hydrocarbon‐CO2 Binary Mixtures in Heat Pump‐Based Thermal Energy Storages

Energy Technology, Volume 14, Issue 4, April 2026.
Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
