Résumé

The evolution of air conditioning systems, alongside new refrigerants, highlights the importance of studying compressor lubricants. Employing nanolubricants in heating, ventilation, and air conditioning (HVAC) systems will result in improvement in heat transfer, reduction in energy consumption, and overall system performance enhancement, thereby advancing efficiency in HVAC systems operations. In this work, we integrated short single-walled carbon nanotubes (Short-SWCNTs), short multi-walled carbon nanotubes (Short-MWCNTs) as well as graphene into POE32 oil to enhance the overall thermophysical and tribological properties of the mixture for compressors applications. Stability characteristics such as dispersion stability and sedimentation behavior were assessed using the two-step method to ensure the uniform dispersion of nanoparticles within the oil and enhance the homogeneity of nanolubricant. In this study, the investigated nanoparticles were analyzed at various volume fractions (0.01, 0.025, 0.05, and 0.1 vol.%) to identify the concentration for optimal stability performance. The experimental results showed that the samples have long term stability with short-MWCNT that has the highest stability. In summary, this study is pivotal for optimizing nanofluid stability in energy-efficient air conditioning compressors.
