The Four Sides Sub-Wet Bulb Cell (4SSBC) is an innovative evaporative cooling system designed for outdoor environments, particularly in dry and hot regions. Unlike conventional indirect evaporative cooling systems, which typically rely on two-sided heat exchange, the 4SSBC introduces a four-sided heat exchange process. This unique configuration significantly enhances cooling efficiency while reducing water consumption. The 4SSBC utilizes porous materials, including ceramics and synthetic media, for optimized heat and mass transfer. Furthermore, the 4SSBC is designed to be integrated into decorative cooling structures for recreational outdoor spaces, providing a more comfortable environment for occupants. The system ensures that fresh air is produced without excessive humidity, offering a sustainable and efficient solution for outdoor comfort in recreational areas during night time.
