WebShown in Fig. 1 is a schematic of earth-air heat exchanger. It is a very simple configuration, a large diameter tube is put into the soil, through which the air flows. The resulting temperature profile is shown in Fig.1 on the right. The soil temperature was set at 10 ºC, and air inlet temperature was taken to be 25 ºC.
