摘要

Nanofluids are being considered as an efficient heat transfer fluid in various thermal applications. In this work, an experimental study was conducted on TiO2nanoparticle mixed with R600a as the working fluid. TiO2-R600a nano-refrigerant was used in a domestic refrigerator with little system reconstruction. The refrigerator performance was then investigated using test parameters including: Pull down test, specific compressor work-input, refrigeration effect and coefficient of performance (COP) using steady state analysis. The results indicate that TiO2-R600a nano-refrigerant works efficiently and safely in the refrigerator and the performance was better than the pure R600a system. Overall, 0.1g TiO2in 40g R600a nano-refrigerant mixture had the highest refrigeration effect and COP and gave the least specific compressor work-input within the test rig.
