Résumé

Nowadays, sales of new refrigerators amount to 150 million units annually. Also, electricity consumption resulting from the use of refrigerators and cooling devices constitutes %6 of the global electricity consumption. Energy regulation and labelling which came in force last year urge all manufacturers to pull up the energy efficiency of all products. Since compressor is playing a heart-like role in the refrigerator energy efficiency, most of the engineering studies lens on the improving performance of the refrigerator compressors.
Basically, dividing performance of the compressor in three main parts such as electrical motor, thermodynamic and mechanical, compressor oil can be classified as main issue affecting not only mechanical efficiency but also reliability of the compressor. Therefore, research on understanding petrochemical ingredients in lubricating oils become an evolving field in recent years. From this point of view, ensuring higher mechanical efficiency in compressors basically depends on the improvements in the lubricant.
In this study, three different compressor oils have been chosen which have different chemical contents and viscosities. The performance of the oils has been evaluated with enhanced lifetime tests which simulate harsh operating conditions in the field. Used oils have been analyzed after the lifetime tests. The results between fresh oil and used oil have been compared. GC-MS and GC-SIMDIS have been used to determine organic molecules and their structural changes. Moreover, ICP-MS has been used for the inorganic particle changes. The main purpose of this study is to determine the compressor oil contents and how these structural changes could cause an effect over the wearing properties of the compressors. With developing these analysis and make the comparison between the oil and their used version, it can be simulated which oil is more effective for the compressor system than the others.
