With the rapid development of modern agricultural technology, greenhouse facilities have become a cornerstone of agricultural production, and their application are becoming increasingly widespread. They play a significant role in enhancing agricultural productivity and crop quality. However, in practical application, particularly from morning to noon, the gradual increase in solar radiation intensifies the photosynthetic activity of plants inside greenhouses, leading to a significant rise in carbon dioxide consumption. This phenomenon not only reduces the concentration of carbon dioxide within greenhouses, but also limits the efficiency of photosynthesis to some extent, thereby adversely affecting the growth of greenhouse crops and potentially impacting the economic returns of agricultural production. To address this challenge, in this study, carbon dioxide release devices were introduced as a solution, and the effects of different placement positions of these devices on the distribution of carbon dioxide concentration within greenhouses were compared and analyzed applying analogue simulation methods. Through precise data collection and processing, this study aimed to determine the optimal placement position for carbon dioxide release devices to optimize the internal airflow distribution and enhance the utilization efficiency of carbon dioxide. |
