Résumé

Hydrofluorocarbon (HFCs), due to their high global warming impact, are not considered a desirable solution for future household application. In accordance to the Kigali Amendment to the Montreal Protocol, numerous countries committed the significant phase-down of the production and consumption of HFCs over the next two to three decades. Natural refrigerants as well as their blends are considered viable alternatives due to their low global warming potentials. Additionally, the use of non-azeotropic refrigerant blends can positively influence the cycle performance of refrigerators and heat pump tumble dryers. Moreover, the knowledge about the behaviour of the oil-refrigerant-mixture is a necessity to enable a more precise component design and dimensioning. While most pure refrigerants are experimentally well investigated, the properties of specific refrigerant blends and especially their oil-refrigerant-mixtures need to be measured. This paper describes the initial experimental investigations of pure propane (R290) and pure iso-butane (R600a) in mixture with a mineral oil (MO). The presented results serve as basis for further investigations and conclusions regarding the ternary mixture, i.e. the refrigerant blend with the mineral oil. Several test benches were built to investigate the properties of interest, such as vapour pressure, viscosity as well as the density of the mixtures.
