The problems with lubrication in refrigeration compressors are usually caused by the presence of the oil-refrigerant mixture in friction nodes. One cannot assess lubricity properties of oil under its operating conditions based on test results that characterize oil exclusively. For this purpose, it is necessary to test the lubricity properties of the oil-refrigerant mixture. The article presents the concept of an assessment method for the lubricity properties of oils for refrigeration compressors in a mixture with a refrigerant. The essential elements of the proposed method are the procedure for selecting wear test duration time (τ_t) and the oil-refrigerant mixture formation time (τ_m).

W sprężarkach chłodniczych problemy ze smarowaniem zazwyczaj spowodowane są obecnością mieszaniny olej–czynnik chłodniczy w węzłach tarcia. Nie można skutecznie ocenić właściwości smarnych oleju do sprężarek chłodniczych w warunkach jego eksploatacji na podstawie wyników badań charakteryzujących tylko olej. W tym celu konieczne jest wykonywanie badań mieszaniny olej–czynnik chłodniczy. W artykule przedstawiono koncepcję metody badań pozwalających na ocenę właściwości smarnych olejów do sprężarek chłodniczych w mieszaninie z czynnikiem chłodniczym. Istotne elementy proponowanej metody to procedura wyznaczania czasu trwania testu zużyciowego (τ_t) oraz czasu wytwarzania mieszaniny (τ_m).
