CFD Simulation Studies on Integrated Approach of Solar Chimney and Borehole Heat Exchanger for Building Space Conditioning

摘要

In this communication, integrated approach of solar chimney and borehole heat exchanger has been studied by using computational fluid dynamics software. It is observed that, the room temperature can be maintained at 25-30 °C, at 4.9 ACH with this integrated approach in both peak summer and winter conditions. The cooling and heating effects are evaluated as 4.73-5.55 kW at 40 °C in summer and 8.27-10.56 kW at 5 °C in winter. The SC-BHE integrated system approach produced 21-37 % higher heating effect than the BHE alone system. In?cooling mode SC fitted after the room in fluid circuit and it produces the induce effect for air suction from BHE along the air blower. So, integrated approach is a feasible solution for building space conditioning.
