: Earth Tube Heat Exchanger (ETHE), Computational Fluid Dynamics (CFD), Heating, Different Velocities
The consumption of high-grade energy has increased considerably with growing needs to achieve thermal comfort conditions inside buildings, residential, greenhouses, livestock buildings, etc. Numerous alternative techniques are being currently explored to achieve thermal comfort conditions inside buildings. The earth–air heat exchanger (EAHE) is a promising technique which can effectively be used to reduce the heating/cooling load of a building by preheating the air in winter and vice versa in summer. With the help of ETHE we can reduce the energy consumption required for space. Research of ETHE was carried out at beginning as a field investigation. For the CFD simulation analysis the pipe of 30 m length, 0.005m thickness and 0.195 m diameter, The temperature value considered for inlet is days in month of January from 5 Jan 2018 to 11Jan 2018 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.
