摘要
The ir-reversibility at the process of vapour-compression refrigeration system (VCRS) with nanoparticles in the working fluid was investigated experimentally. Mineral oil (MO) with 0.1 g L-1 TiO2 nanoparticles mixtures were used as the lubricant instead of SUNISO 4GSI oil in R22, R134a, R290 and R40.7C VCRSs. The VCRS exergy efficiency at the process with the nanoparticles was then investigated using second law of thermodynamics. The results indicate that R22, R134a, R290 and R407C, and MO with TiO2 nanoparticles work normally and safely in the VCRS. The VCRS exergy efficiency at different process was better than the R22, R134a, R290 and R407C and SUNISO 4GSI oil system. Thus, TiO2 nanoparticles can be used in VCRS with rotary compressor to considerably increase the exergy efficiency at the process.
