Abstract

An Earth Tube Heat Exchanger uses the massive thermal energy of the ground for the air heating in winter due to the temperature difference between the air and underground surface. With the help of ETHE we can reduce the energy consumption required for space. However, for determining the surface heat convection, due to lack of available methods it is difficult to make accurate energy simulation and design. Research of ETHE was carried out at beginning as a field investigation. But now CFD simulation is used for accurate heat transfer. In use of complex dimensioning process required such a system, which involves optimization of numerous parameters such as the diameter, air flow rate depth, tube length and condensation in the meantime have to be considered. For the CFD simulation analysis the pipe of 30m length, 0.003m thickness and 0.15 m diameter, The temperature value considered for inlet is days in month of January from 5 Jan 2017 to 11Jan 2017 at hourly according the climate of Bhopal, M.P. has been taken to observed for the outlet blow with different velocities. Using the CFD analysis it is observed at low air velocity that rate of heat transfer and performance increases in winter.
