Polyolester (POE) oil and mineral (Min) oil are widely used in household refrigerators as compressors lubricants in India. An experimental calculation on the thermal, chemical, corrosion, and nature‐friendly properties of POE oil and Min oil suspended with silica nanoparticles is conducted for confirming its practicality to adopt in refrigeration compressors as nanolubricant. No surfactants were used for synthesizing the nanolubricants. The mass fractions from 0.01% to 0.2% and temperatures from 25°C to 85°C are considered. The thermal conductivity and fire point increased as SiO₂ mass proportions increased. The pour and cloud points decreased, and in the corrosive nature, apparently little effect was observed by adding SiO₂ nanoparticles. The total acid number (TAN) and saponification number increased with the increase in SiO₂ nanoparticle concentration. All the synthesized nanolubricants were biodegradable and a little toxic. Refrigerant compressors with long life, with smooth and safe working are expected using POE oil and Min oil with up to 0.2% SiO₂ (without surfactants) because of augmented thermal properties and less influenced corrosive, chemical, and eco‐friendly properties.
