Nanofluids characterization and application as nanolubricants in heat pump systems
In the last years, various applications have been proposed for nanofluids in the HVAC&R field; their use as primary and secondary fluids, also as lubricants, has been kept into account to improve 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 or mineral oil as a base fluid, and titanium oxide (TiO2) or single-wall carbon nano-horns as nanoparticles, were studied in a dedicated test rig. In contrast with some published data, no improvement was detected with 0.05 to 0.5 wt% of TiO2 or 0.1 wt% of single-wall carbon nano-horns in tested commercial oils. All results will be discussed in depth in the article.
