THE ESTIMATION OF THE INFLUENCE OF MIXTURE COMPRESSOR OILS AND REFRIGERANTS ON THE DURABILITY OF NODES OF FRICTION IN COLLING COMPRESSORS
Journal Title: Tribologia - Year 2010, Vol 232, Issue 4
Abstract
At present lasts the process of changing an old refrigerating mediums (freon which contain chlorine) for new ones, which are more environmental friendly. Apart from an important matter of oils mixing with refrigerating mediums in a wide range of temperatures and pressures, it’s necessary to provide those mentioned mixtures with adequate form of anti-friction and anti-wearing out properties. That’s why the report contain of literature informations about the scientific researches of quantitative estimate of wearing out of cooling compressors parts in the oil environment which is polluted by refrigerating mediums. The trial of the definition of the influence of the mixture of oil with the refrigerating medium for wearing out the steel and cast iron parts were made.<br/><br/>
