Potential of Nanorefrigerant and Nanolubricant on Energy Saving in Refrigeration System – A Review

Refrigeration system is one of the biggest reason of the expanding pattern of energy consumption, thus, energy saving is one of the best approach to overcome this issue. Nanofluids show extraordinary potential in upgrading the thermodynamic and mechanical performance of the refrigeration system. In...
