Application of response surface methodology in optimization of automotive air-conditioning performance operating with SiO2/PAG nanolubricant

The effect of compressor speed, initial refrigerant charge and volume concentrations of SiO2/PAG nanolubricant on the performance of automotive air-conditioning (AAC) system are investigated in this study. Response surface method (RSM) was used in designing the experimental work and is based on face...
