The picture shows the gymnastics competition venue for the Chengdu Universiade. Zhang Lang took a few hours to achieve "ice basket" conversion, intelligent control of venue temperature, and recycling of rainwater for green irrigation... The Chengdu Universiade is about to open. Recently, reporters from China News Network visited multiple competition venues and learned that many "black technologies" will effectively ensure the smooth progress of the event, while achieving green and low-carbon development. The picture shows the basketball final venue of the Chengdu Universiade. Zhang Langzhao quickly achieved the "ice basket conversion" into a standard multi-functional hall located in Dong'an Lake Sports Park, Chengdu. It is a super large Grade A sports hall that can accommodate 18000 people and has approximately 18000 seats. During the Chengdu Universiade, this venue will undertake gymnastics group events and finals, resulting in a total of 14 gold medals. In addition to gymnastics competitions, this place can also host 16 sports events such as basketball, ice hockey, badminton, as well as large-scale cultural and artistic performances, commercial activities, etc. Standing in the center of the venue, Luo Xingxing, deputy manager of the logistics support department of the gymnastics venue center in Dong'an Lake Sports Park, told reporters that as it is a multi-functional venue, the speed of conversion between various competition venues is crucial, with the most eye-catching being the 4-hour conversion between ice hockey and basketball competition venues. Pointing to the gray concrete ground under his feet, Luo Xingxing said that there is "a lot of heaven and earth" in it. It is understood that there is a layer of cold water pipe and a layer of hot water pipe under the court. When the Basketball court is converted to an ice court, the movable wood floor is first removed, and then the cold water pipe is used to keep cooling down to minus 9 degrees Celsius. After that, the ice is sprayed and frozen continuously, and finally a 9 cm thick ice surface is formed, then the ice hockey game can be played. This technology of quickly converting competition venues seems to have become a "standard" feature in some of the venues of the Universiade. The Phoenix Mountain Sports Park Ice Basket Gymnasium, which undertakes the basketball finals of the Universiade, can achieve a 3-hour "ice basket conversion". This rapid venue conversion technology provides a technological foundation for venues to host various competitions, "said Liu Decheng, Deputy Chief Architect of China Southwest Design Institute No. 9.

Recently, Chengdu has issued a continuous high-temperature orange warning, and the outdoor temperature of Dong'an Lake Sports Park in Chengdu has exceeded 36 degrees Celsius. But as soon as the reporter walked into the multi-functional hall responsible for the gymnastics competition at the Universiade, he felt a chill. Even more surprising is that the venue does not have air conditioning on. Why can we achieve low temperature without turning on the air conditioning? Luo Xingxing introduced that this is related to the geographical location, orientation, and insulation materials of the external walls of the venue. "When there are few people, the venue does not need to turn on air conditioning, and when there are many people, it is necessary." "All the stands of our entire venue, including the center area, are equipped with temperature sensors, which can analyze the overall data at any time." Luo Xingxing said that gymnastics competitions require a constant room temperature between 23 degrees Celsius and 24 degrees Celsius, At this point, the temperature sensing probe plays a crucial role. And inside the ice hockey and basketball stadium of Fenghuangshan Sports Park, the temperature is also comfortable. Liu Decheng introduced that the black circular pipes above the center of the stadium are high-altitude air conditioning vents, located at a height of 35 meters, but the wind can blow up to an area 1.5 meters above the ground. When the wind reaches a height of 1.5 meters above the ground, the wind speed control of the entire area
