Thermal performance analysis of EAHE with and without fins arrangements

( Volume 2 Issue 6,June 2015 ) OPEN ACCESS

Rahul Rathee, Dr. Atul lanjewar


An Earth air heat exchanger(EAHE) uses  the earth as the thermal source and sink for economical, energy efficient, space heating and cooling. The temperature of earth at a certain depth about 4m the  temperature  of  ground  remains nearly constant throughout the year.This  constant temperature is called the undisturbed temperature of earth  which  remains  higher than the outside temperature  in  winter  and  lower  than  the  outside temperature in summer.When air is passing throught buried pipes it will become hot in winter and cold in summer as compared to outside temperature.EAHE generally uses for passive heating or cooling.This paper presents effect of temperature drop or rise due to fins in horizontal arrangement. In this paper comparsion of COP v/s Reynolds number,temp difference v/s Reynolds number and Nusselt number v/s  Reynolds number will be done.
