Abstract
Air will be cooled between stages in almost all applications of multi-stage compressors, a process known as intercooling. Compressor intercooling is essential for effective operation. The compression is closer to an isothermal compression with intercooling, requiring less power as a result. The compressed air is cooled between stages using an intercooler, which is essentially a heat exchanger. Power loss between the piston and cylinder occurs as a result of the unfavourable effect of friction. Nanoparticles may be added to lubricant to cool the air and increase compressor efficiency. The rolling action, greater cooling, protective coating, and anti-wear capabilities of nano particles in lubricant are the primary contributors increasing compressor efficiency. The objective of the performance enhancement study is to investigate the effects of incorporating graphene nanoparticles (GNP) into lubricating oil in a two-stage reciprocating compressor. Aim is to evaluate the potential improvements in compressor efficiency, reduced wear, and enhanced heat dissipation, leading to overall enhanced performance. High surface area graphene nanoparticles are combined with 500 ml of engine oil in the current study. To have three different samples a mixture of 0.5, 1.0, and 1.5 gram of graphene are added to 500 cc of engine oil. Temperatures before and after the intercooler, viscosity, volumetric efficiency, and the two-stage compressor’s isothermal efficiency are all measured. The results show that adding graphene nanoparticles to lubricant enhances compressor performance.
