Analysis demonstrates enhanced cooling performance in a coupled solar ventilation-evaporative cooling system, indicating optimal conditions for natural ventilation.
This study presents an innovative design for a sustainable Coupled Solar Ventilation-Evaporative Cooling (SVEC) system. It utilizes a wall solar chimney to generate natural ventilation, directing waste hot, dry air through a humid hay bed on the roof to induce evaporation and create a cooling effect. The resulting cold is transferred via a thermally conductive plate, while a membrane condenser recovers moisture for reusing it. A mathematical model governing the evaporation process permits to analyse steady-state cooling performance. Simulations explore how inlet air temperature, airflow rate, humidity ratio and hay moisture content influence cooling, revealing optimal conditions for enhanced performance.
