Abstract

Because of the temperatures differential between the environment and the subsurface, an Earth Air Tube Heat Exchanger (EATHE) uses the thermal energy of the ground for air conditioners in the winter and air cooling in the summer. Everyone can lower the amount of energy needed for space heating or cooling with the aid of EATHE. However, it is challenging to create precise energy simulations and designs for calculating surface heat convection as because there aren’t many techniques available. The initial research on EATHE was conducted as an independent study. But now software simulation is used for the measurement of heat transfer. It necessitates a sophisticated system that optimizes a number of parameters, including the diameter, air flow rate depth, tube length, and condensation, all while taking into account other factors. For simulation and modeling, ANSYS software will be utilized. Computational Fluid Dynamics (CFD Fluent) workbench will be used to simulate the 45-meter-long, 0.004-meter-thick, and 0.08-meter-diameter pipe. Air velocity is measured at 1 m/s and the pipe is 5 m below the surface of the earth. The temperature value was considered for the inlet for a day from June (2016) to May (2017) according to the climate of Bhopal, M.P. which has been declared by the government of Madhya Pradesh. The effect of heat transpiration the magnitude to different parameters of the design can be analyzed using the CFD model, and the parameters that were found to be influential were noted. To determine the statistical connections between the parameters specified in the design and the local heat convection rate, a large number of CFD simulations may be run based on the actual situations. The rate of heat transfer, mid-temperature, and outlet temperature are likely to change between the two seasons at a faster speed.
