Study on the Optimized Layout of CO₂ Emission Devices from the Perspective of Greenhouse Flow Field Dynamics

Abstract In the rapid development of modern agricultural technology, greenhouse facilities have become an important cornerstone of agricultural production, with increasingly wide applications and significant implications for improving agricultural production efficiency and crop quality. However, in practical applications, especially during the morning to noon period, due to the gradual increase of solar radiation, the photosynthesis activity of plants in the greenhouse also intensifies, resulting in a significant increase in carbon dioxide consumption. This phenomenon not only reduces the carbon dioxide concentration in the greenhouse, but also limits the efficiency of photosynthesis to a certain extent, thereby adversely affecting the growth of greenhouse crops and ultimately potentially affecting the economic benefits of agricultural crops. To address this challenge, this study introduces carbon dioxide release devices as a solution, and through simulation methods, comparatively analyzes the impact of carbon dioxide release devices placed in different positions on the carbon dioxide concentration distribution in the greenhouse. Through precise data collection and processing, this study aims to determine the optimal placement position of carbon dioxide release devices to achieve the optimization of airflow distribution inside the greenhouse and improve the utilization efficiency of carbon dioxide.
