The soil thermal analysis in the neighbor of ground source heat exchanger of the heat pump

Abstract

The aim of this article is thermal behavior of ground source heat exchanger during the one year measured period. It represents soil temperature dependences on the depth under the terrain during the time. The ground source heat exchangers introduce a very interesting and important alternative source of energy which has a very good possibility for using not only in residential buildings in future.
In the article, daily, monthly and annual dependences of soil temperatures from particular sensors, placed in the system of ground source heat exchanger are analyzed.
Generally known rule that with the growing depth under the terrain the temperature of soil is less influenced by the weather conditions with the measured dates is validated. At the same time stands up the question, to which depth the soil is able to regenerate itself and when it cannot be revive by reason of big depth under the terrain.
Than it is necessary to consider the local conditions if it is better to use ground source heat exchanger or to make a borehole.
