Abstract

This paper is performed to investigate of cooling effect and total enthalpy variation on EAHES(Earth-to-Air Heat Exchanger System) that is buried 3m depth and 60m length. Using EAHES, the reduction of the sensible heat is obviously but latent heat is showed increased trend. Although the outdoor average latent heat accounts for 53.2% of total enthalpy, latent heat of the exit air from EAHES was raised as 58%. For improving cooling effect of EAHES, it has to considered that how to remove the latent heat from EAHES.
