This short communication presents an evaluation of cooling efficiency in an agricultural greenhouse located at Al Kuwaitat Research Station, Al Ain, UAE, under the climatic conditions of Abu Dhabi. The study focused on comparing fan configurations, with particular attention to the performance of upper fans. Among the tested scenarios, running only the upper fans (Scenario 2) demonstrated the most effective cooling performance, as indicated by significant temperature differences recorded across multiple sensors. This enhanced cooling effect is likely due to improved airflow patterns and heat dissipation facilitated by the strategic placement of the upper fans. To ensure the accuracy and continuity of temperature data, sensors were regularly maintained and calibrated, and a redundant system was implemented to prevent data loss. These measures helped avoid gaps in the dataset, which are critical for reliable analysis. The findings highlight the importance of fan configuration and data integrity in optimizing greenhouse climate control under arid conditions.
