There are no international standards guiding tribological testing in oil-refrigerant mixtures. The conditions for tribological tests, including sliding velocity, are chosen arbitrarily. The article presents an attempt to examine the influence of the sliding velocity of friction pair elements on the coefficient of friction and lubricating properties of compressor polyester oil (POE) and its mixture with the R452A refrigerant (POE/R452A) under starved lubrication conditions. The R452A refrigerant is currently widely used in transportation refrigeration. The authors’ original test procedure with the use of a model block-on-ring type friction pair was applied to evaluate the lubricating properties of the oil-refrigerant mixture. Tests were conducted in three operational situations: no lubrication, starved lubrication with POE oil, and starved lubrication with the POE/R452A mixture. In each case, the tests were performed at different sliding velocities and the same sliding distance. A series of tests was also conducted where the load was increased in steps by 20 N to determine the relationship between the coefficient of friction, sliding velocity, and load on the friction pair The results support the potential use of higher sliding velocities and the reduction in test duration. For starved lubrication with the POE oil and the POE/R452A mixture, the differences in wear at specific velocities for the same sliding distance reached up to 30%, and the rankings of lubricating properties at different velocities remained unchanged.

Badania tribologiczne w mieszaninie olejczynnik chłodniczy nie są objęte żadnymi międzynarodowymi normami. Stosowane warunki testów tribologicznych, w tym prędkość ślizgania, są dobierane w sposób uznaniowy. W artykule przedstawiono próbę sprawdzenia wpływu prędkości ślizgania elementów węzła tarcia na wartość współczynnika tarcia i właściwości smarne sprężarkowego oleju poliestrowego (POE) i jego mieszaniny z czynnikiem chłodniczym R452A (POE/R452A) w warunkach skąpego smarowania. Czynnik chłodniczy R452A jest aktualnie szeroko wprowadzany do stosowania w chłodnictwie transportowym.Wykorzystano własną metodę oceny właściwości smarnych mieszaniny olej–czynnik chłodniczy z wykorzystaniem modelowego węzła tarcia typu rolka–klocek. Wykonano badania przy trzech sytuacjach eksploatacyjnych: bez smarowania, przy skąpym smarowaniu olejem POE i przy skąpym smarowaniu mieszaniną POE/R452A. W każdym przypadku wykonano testy przy różnych prędkościach ślizgania i takiej samej drodze tarcia. Wykonano również serię testów, w której skokowo zwiększano obciążenie ze skokiem 20 N celem określenia zależności współczynnika tarcia od prędkości ślizgania i obciążenia węzła tarcia.Wyniki badań potwierdzają możliwość wykorzystania większych prędkości ślizgania i skrócenia czasu przeprowadzania testów. Przy skąpym smarowaniu olejem POE i mieszaniną POE-R452A różnice dla poszczególnych stopni prędkości przy tej samej drodze tarcia wznosiły maksymalnie 30%, a rankingi właściwości smarnych dla różnych prędkości pozostają takie same.
