Earth Air Heat Exchanger (EAHE) exploits the earth’s ground temperature to its maximum potential so as to carry out
the heat transfer. This paper mainly focuses on the methods that are being used to improve the thermal efficiency of
the EAHE, during its course of operation. Studies conducted by various researchers in the field of EAHE, regarding the
method and modification done on the EAHE so as to improve its performance of heat exchange has been discussed in
this paper. The paper also deals with the design aspects and parameters affecting the performance of the EAHE, which
help in dealing with its installation and implementation.
