Covering of heating load of object by using ground heat as a renewable energy source

Abstract

Rational use of energy, improving energy performance of buildings and use of renewable energy sources are the most important measures for reducing consumption of non-renewable primary energy (solid, liquid, and gaseous fuels), environmental protection and for the future sustainable development of mankind. In the total primary energy consumption great part is related to building industry, for heating spaces in which people stay and live. Renewable energy sources present natural resources and they are one of the alternatives that allow obtaining heat for heating buildings, and by that they provide a significant contribution to the energy balance of a country. This paper analyzes the participation of ground source as renewable energy sources, when the vertical (the probe in the ground) and horizontal (registry in the ground) heat exchangers are used for covering heating load of the building.
