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.

二氧化硅纳米颗粒对制冷剂压缩机润滑油的热，化学，腐蚀性和自然友好特性的影响—对比研究

聚酯油（POE）和矿物油（Min）在印度的冰箱中已广泛用作压缩机润滑剂。对悬浮在二氧化硅纳米颗粒上的POE油和Min油进行了热，化学，腐蚀和自然友好性质的实验计算，以确认其在制冷压缩机中用作纳米润滑剂的实用性。没有使用表面活性剂来合成纳米润滑剂。考虑质量分数为0.01％至0.2％和温度为25℃至85℃。随着SiO _2的质量比例增加，热导率和着火点增加。倾点和浊点降低，并且在腐蚀性质中，加入SiO ₂几乎没有观察到效果纳米粒子。总酸值（TAN）和皂化值随着SiO ₂纳米颗粒浓度的增加而增加。所有合成的纳米润滑剂都是可生物降解的，并且毒性很小。预期使用具有0.2％SiO ₂（不含表面活性剂）的POE油和Min油的长寿命，平稳，安全的制冷压缩机，因为它具有增强的热性能，并且对腐蚀，化学和环保性能的影响较小。
