Abstract

The project is about a research on thermophysical properties of copper (II) oxide nanoparticles suspended into host refrigerant and the heat transfer performance of a condenser. Increasing the heat transfer rate of thermal system is something that researchers and engineers are aiming for. This is to increase the thermal efficiency of the system and thus, improves energy consumption savings. So, the idea of having nanoparticles suspended into a refrigerant makes it an important field to be studied due to its amazing enhancement in thermal conductivity and heat transfer rate. In this research, R407-C is selected as the host refrigerant and the design of the condenser is a simple horizontal tube of 0.5 meter in length and 11.7 millimeter in diameter. The mathematical modeling is used to investigate the thermal conductivity, viscosity and heat transfer of the nanorefrigerant with the volume fraction of the nanoparticles as its variable from 1% to 5%. The CFD simulation is also used to investigate the heat transfer performance of a condenser. These methods prove that there is big enhancement in thermal conductivity, viscosity and heat transfer with the effect of copper (II) oxide nanoparticles in R407-C.
