Özet
Ground temperature distribution is crucially important for ground source heat pump applications. Ground
can be composed of one or multi-layers. In this study, one and multi-layer ground temperatures were calculated
numerically considering the climatic conditions of Adana-Turkey. The accuracy of the results obtained from
numerical method was controlled using the ones analytically obtained for exactly the same simplifying assumptions.
It was shown that the simplifying assumptions for analytical calculations were not realistic. In the numerical
calculations, daily values of solar energy, relative humidity, wind velocity and ambient temperature were used for
yearly calculations of ground temperature distribution. Variation of ground surface properties with the months in a
year has significant effects upon temperature distribution. The depths for maximum and minimum temperatures in the
ground were very different in case of multi-layered grounds existing naturally or built artificially. Above mentioned
effects can be used to control ground temperature distributions in winter and summer.
