Evaluation of Environmental Sustainability of Nanofluid Use in Cooling Systems

Nanofluids are used to increase cooling efficiency in many areas such as electronic cooling systems, solar energy, aviation and space sectors, nuclear facilities. Nanofluids are obtained by homogeneous dispersion of nanometre sized particles in base fluids such as water, ethylene, glycol, oil. The production of nanoparticles consists of stages such as preparation of nanofluids, mixing of nanoparticles and increasing stability. These stages include important environmental parameters such as water use, waste generation, energy consumption, carbon footprint formation. The use of nanofluids in cooling systems has many negative effects on environmental sustainability such as toxicity, corrosion when metal-based nanoparticles are used, high energy requirement during nanoparticle production, excessive and expensive use of natural resources, water pollution. In this study, important issues such as the classification of environmental impacts that occur during the production and use stages of nanofluids and increasing environmental sustainability will be examined in detail. Opinions on how the design of sustainable cooling systems can be realised by reducing the environmental damages caused by the use of nanofluid will be given.
