Résumé
In the past few years, various applications have been proposed for nanofluids in the Heating, Ventilation, Air Conditioning and Refrigeration (HVAC&R) field; their use as primary and secondary fluids, also as lubricants, was kept into account to improve the systems performance. The present work was developed to test the applicability of nanofluids as lubricants in the compressors of heat pump systems, with the purpose to experimentally detect the possible positive effects of nanolubricants. Several nanolubricants, formed by Polyolester (POE) or mineral oil as base fluid, and titanium oxide (TiO2) or single wall carbon nano-horns (SWCNH) as nanoparticles, were studied in a dedicated test rig. In contrast with the published literature, no improvement was detected using nanofluids instead of commercial oil. All results will be discussed in detail in the paper.
