1. The venue's spacious and open layout makes it difficult for traditional cooling equipment to cover the entire area, resulting in severe thermal stratification. In summer, the sports area becomes unbearably hot, leading to a poor viewing/training experience, discomfort for participants, and reduced efficiency.

2. Traditional cooling methods have significant drawbacks: small fans provide insufficient coverage and have limited effectiveness; central air conditioning is extremely energy-intensive and costly; localized cooling can cause excessive temperature differences, increasing the risk of colds and disrupting events.

3. Poor air circulation in high-humidity areas such as swimming pools promotes mold and odor growth, and condensation on the floor increases the risk of falls and equipment corrosion, shortening the venue's lifespan.

4. During events/training, the high density of people generates significant amounts of heat, carbon dioxide, and sweat. Poor air circulation leads to odor buildup, bacterial growth, discomfort, health risks, and reduced visitor retention.

5. The complex equipment and traffic flow within the venue, along with the numerous wiring connections for floor cooling equipment, increases the risk of collisions, electric shocks, and other safety accidents. It also occupies sports space and hinders events and training.

6. Large venues need to cover a huge cooling area. Traditional systems occupy a lot of space and consume a lot of energy, which greatly increases operating costs and does not meet the requirements for energy conservation and cost reduction.
