Theoretical Analysis on Application of Nanofluids in Ground Source Heat Pumps for Building Cooling

Abstract

A theoretical study has been carried out to compare the heat transfer and fluid dynamic performance of water-based nanofluids as working fluids. With different volumetric concentrations (0-4 %) of nanofluids, a theoretical analysis was done to study the performance of Heat Pump for space cooling application. Also, a comparison was made to study the effect of ground temperature on pumping power and heat transfer. One more comparison has drawn to study COP of the GSHP with ground temperature. The 4% CuO nanofluid possess highest COP index about 3.58 among all other nanofluids and basefluid. The present study reveals that nanofluids can be an effective heat transfer fluid for GSHP application which needs to be explored more in future.
