In this paper, the combined performances of a solar chimney and Earth-to-Air Heat Exchanger (EAHE) system have been computationally studied. The study focuses on improving passive solar heating and ventilation in buildings by blending the natural ventilation effects of a solar chimney with thermal moderation provided using an EAHE. Airflow patterns and temperature distributions are then modeled using CFD simulations. Performance parameters such as airflow rates and temperature distribution are examined. The integration of these two technologies offers a sustainable solution to improve energy efficiency and indoor air quality. Results provide important valuable insights on design optimization and operational performance of such systems, which establish a basis for future developments in the field of sustainable building design.

摘要

In this paper, the combined performances of a solar chimney and Earth-to-Air Heat Exchanger (EAHE) system have been computationally studied. The study focuses on improving passive solar heating and ventilation in buildings by blending the natural ventilation effects of a solar chimney with thermal moderation provided using an EAHE. Airflow patterns and temperature distributions are then modeled using CFD simulations. Performance parameters such as airflow rates and temperature distribution are examined. The integration of these two technologies offers a sustainable solution to improve energy efficiency and indoor air quality. Results provide important valuable insights on design optimization and operational performance of such systems, which establish a basis for future developments in the field of sustainable building design.
