As global climate change worsens and temperatures rise year after year, people are prone to discomfort and even heat stroke during outdoor activities. people to feel uncomfortable during outdoor activities and even increase the risk of heat stroke, thus reducing their willingness to go out. This has led to an increase in the risk of heatstroke and a decrease in people's willingness to go out. In order to improve this situation, we apply Bernoulli's principle and Jarley's elements (geometric array) to design innovative The public facilities for outdoor cooling are designed by applying Bernoulli's principle and Jali's elements (geometric array) to enhance the air flow and cooling effect of the environment. ventilation and environmental cooling effect, to create a more pleasant activity environment for the city and public space, so that the people The design of outdoor cooling public facilities is based on scientific principles to enhance air circulation and environmental cooling effect, creating a more pleasant environment for urban and public spaces, and enabling people to enjoy outdoor life comfortably even in hot weather. The design will enable people to enjoy outdoor life comfortably in hot weather. Translated with DeepL.com (free version)
