Konvekcinių šilumos mainų grunte įtakos šilumos polių efektyvumui modeliavimas ; Modeling of Influance of Convective Heat Transfer in Soil on Thermal Poles Efficiency
Geothermal energy is widely used in building to satisfy heating and cooling needs. The reason for this is that geothermal energy can be extracted almost all over the world and this renewable energy source very slightly depending on ambient conditions. There are many different types of collector for geothermal energy extracted from the ground, but in recent years, much attention is given to heat piles. Energy piles efficiency strongly depends on the soil parameters: soil thermal conductivity, heat capacity, soil medium porosity, water content in soil and its flow direction. Listed natural environmental parameters on the thermal efficiency of the energy pile is a well-studied, but so far very little attention is dedicated to artificial methods which can be used to increase the thermal efficiency of the piles. One such method - air well installation in the ground or pile. Thera only a few studies which analyzing the air well influence to energy pile efficiency whwn air well is installed in pile. But there is no studies which have evaluated the impact of air well influance to energy piles system. In the first part of this study I reviews the literature and research work related to geothermal energy, heat piles and soil parameters on the thermal efficiency of the energy piles. In the second part I describe in detail the model of energy piles system and air well witch is installled between piles. The third part contains the simulation results and conclusions.
