Mutual solubility and VLLE correlation for the R32 + R290 system
Fluid Phase Equilibria, 2003Following our recent study on vapourliquid-equilibrium (VLE) of the difluoromethane (R32) + propane (R290) system, that covered the temperature range between 248.13 and 294.91 K, the present study focused on the behaviour of the liquid phase down to 215 K.

Ticari Buzdolabında R290 Soğutucu Akışkan Performansı
2023In this study, we investigated the impact of the environmentally friendly R290 refrigerant, which has a higher Coefficient of Performance (COP), on the operating performance of the cooling system, as an alternative to the commonly used R404A refrigerant, which has a negative effect on global warming.

Lubricity evaluation of oil–refrigerant mixtures with R134a and R290
International Journal of Refrigeration, 2016Abstract The article presents an assessment method of lubricity properties of oils for refrigeration compressors in a mixture with a refrigerant. The assessment has been based on sample wear volume in the block-on-ring node under the conditions similar to the operation of the compressor following an extensive standstill.

ABOUT EFFICIENCY OF MIXTURES R125/R290 AND R134a/R290 AS WORKING MEDIA OF REFRIGERATING PLANTS
2015The thermodynamic behavior of mixtures R125/R290 and R134a/R290 having different composition in saturation state was considered. The existence of aseotropic mixtures containing 0,6 molar part of R125 and 0,4 molar part of R134a was mentioned. The dependences of saturated vapor and liquid temperatures` differences of mixtures on isobars from pressure ...

PROSPECTS FOR THE USE OF R290 REFRIGERANT IN MARINE REFRIGERATION EQUIPMENT
Journal of Marine Technology and EnvironmentThe need to replace traditional refrigerants in marine refrigeration equipment with low-GWP alternatives is growing due to international climate regulations. This paper discusses the current status and potential of R290 (propane) as a long-term substitute in marine air conditioning systems.
