Abstract
In constructing a hybrid solar updraft tower with an underground heat exchanger, this study provides a theoretical and experimental investigation. A valuable function that lowers energy consumption in the case of domestic buildings is the Underground Tube Heat Exchanger. The submerged underground heat exchanger tube for heating in winter season and cooling in summer and the air is to be supplied by the influence of solar updraft tower to the building. The findings show that at 3 m depth from the earth, which is called buried depth at a 152 mm outer diameter, the maximum efficiency of the underground heat exchanger system. In comparison, with rising velocity of air, the temperature of the outlet air from the ground heat exchanger increases, varying from (22.2- 28 °C) and also increases with increasing pipe diameter and decreases with increasing tube length. The difference between the findings of the theoretical and the experimental tests was 1.8 %. The combined geothermal heat exchanger and solar updraft tower system is used as an air conditioning system and was satisfactory efficient for thermal building loads.
