Abstract

To keep pace with advancements, we also need the energy to keep on running the system. Sustainable development has now become an integral part of development and thus renewable energy is getting the attention that was required for a long. The Ground Source Heat Pump (GSHP) is a passive energy system that can be installed in buildings to reduce the overall HVAC load. A novel pipe design is used to increase the overall heat transfer thus leading to a high heat transfer rate. The novel spirally corrugated pipe design is then tested for different working fluids numerically. The results show that spirally corrugated pipe receives higher temperature drop as compared to the plain pipe. A significant pressure drop is also observed for the spirally corrugated pipe. In cooling mode, a COP of 5.02 and 4.42 is observed for the spirally corrugated pipe and plain pipe respectively. The most economic and the most efficient combination are found.
