Ice Ribbon: The fastest ice, constantly giving birth to new Olympic records
On the afternoon of February 17, at the final of the beijing winter olympics speed skating women's 1000 meters held at the "Ice Ribbon" of the National Speed Skating Hall, Japan's Mifan Takagi broke the Olympic record set by the project at the Pyeongchang Winter Olympics with a time of 1 minute 13.19 seconds. This is the tenth Olympic record for the birth of the "Ice Ribbon" during the Beijing Winter Olympics.
Before the opening of the Beijing Winter Olympics, many people were still relatively unfamiliar with the young ice venue of "Ice Ribbon". It is the only newly built ice competition venue for the Beijing Winter Olympics, which undertakes all the speed skating competitions during the competition, and the 12,000 square meters of ice surface in the venue is called "the fastest ice".
"So many new records have been set since the start of the race, which is enough to prove that this is the 'fastest ice'." Mark Maiser, a Canadian icemaker with ice-making experience at the 6-time Winter Olympics, recently said that the use of carbon dioxide (R744) transcritical direct refrigeration system is the basis for the "ice ribbon" to create the "fastest ice". This innovative refrigeration system makes the ice surface temperature uniform and the temperature difference controlled within ± 0.5 °C, which means that the hardness of the entire ice surface track is consistent, which is very conducive to athletes to achieve good results.
At the same time that the results of the competition "broke the record", the green "report card" of the "ice ribbon" also created a record in the history of the Olympic Games. Mark Maiser said the National Speed Skating Hall's carbon emissions are close to zero, greener and greener. It is understood that the "ice ribbon" will also recover the waste heat generated by the refrigeration system for athletes' domestic hot water, ice melting pool melting, ice surface maintenance and pouring ice, etc., which can save about 2 million kWh of electricity a year.

Ice Cube: From water to ice, the "old stadium" once again amazes the world
14 years ago, the Beijing Olympic Games let the world know and understand China, and also made the two Olympic venues of "Bird's Nest" and "Water Cube" become the iconic landscapes of Beijing and even China. 14 years later, the Beijing Winter Olympics was grandly opened at the "Bird's Nest", and the "Water Cube" was transformed into an "Ice Cube" through the "Water Ice Conversion", which served as a competition venue for curling and wheelchair curling at the Beijing Winter Olympics, allowing people to appreciate the magic of this blue cube again.
"Ice Cube" is the competition venue with the most events and the longest schedule of the Beijing Winter Olympic Games; it is the largest curling venue in the history of the Winter Olympic Games; and it is also the only "double Olympic venue" in the world that can operate both water and ice sports.
The "Ice Cube" curling track is set up on the swimming pool: the water in the pool is first drained, then a convertible frame is set up in the pool, and a detachable ice making system is installed to form a curling field with 4 standard tracks. This conversion mode not only enables the two-way conversion of water and ice to be realized, but also achieves the reuse of conversion materials, which greatly reduces the cost of demolition and transformation in the later stage.
During the Beijing Winter Olympics, "Ice Cube" exuded its unique sense of science and technology while using her gorgeous posture to once again amaze the world.
"I like the little details of the 2008 Beijing Olympics — there's a diving board or something like that behind the screen. You can see what the Summer Olympics and the Winter Olympics look like in the same building, which is amazing. British female curler Jennifer Dodds admits she still remembers that in 2008, swimmer Rebecca Adlington won two gold medals for Britain here, and the building is "absolutely historic" in her mind.

Crystal Shoes: Witness history, the ski jump is preserved forever
A few days ago, the Shougang Ski Jump ended all the competitions of the Winter Olympic Games. In this venue with only four Winter Olympic events, Chinese athletes ended perfectly with "two gold and two silver".
Shougang Ski Jump is the world's first permanently retained and used ski jump, and it is also the first newly built competition venue in the Beijing Winter Olympics area, known as "crystal shoes" because of its shape. At this Winter Olympics, it witnessed the "leap" moments of athletes such as Gu Ailing and Su Yiming, and became the "background board" of extreme sports with its unique "industrial style".
"This is the best track I've ever skated!" Gu Ailing said in an interview after winning the gold that the four Shougangyuan cooling towers next to the ski track fill the big jump with a cool atmosphere, and this is exactly the aura needed for the ski jump.
Shougang Ski Jump is located in the north area of the century-old Shougang Old Industrial Park. The cooling tower mentioned by Gu Ailing is the supporting equipment of the former Shougang Electric Power Plant. After the main steel process of Shougang's old plant was discontinued, four cooling towers were retained as characteristic landmarks of the plant.
Shougang Park let the "industrial wind" blow to the Winter Olympics, and the Beijing Winter Olympics also let the "ice and snow wind" blow into thousands of households. It is understood that the Shougang ski jumping platform in the design, construction at the beginning of the full consideration of the use of the game, after the Beijing Winter Olympics, will undertake domestic and foreign big jumping project sports competitions, become professional athletes and sports team training venue, youth reserve talent selection base, event management personnel training base, etc., directly serve the promotion of ice and snow sports in China.

Snow Dragon: Harmonious symbiosis, Haituo Mountain slides out of the world speed
Chinese athletes practice the Olympic spirit in the beijing Winter Olympic Games and create history again and again. In the men's steel frame snowmobile competition, Yan Wengang won the bronze medal with a total of 4 minutes 01.77 seconds in four rounds, winning the first medal of the project for the Chinese team, and was called "Haituoshan Car God" by netizens.
The steel frame bobsleigh race venue is at the National Bobsleigh Center in Haituoshan, Yanqing District, Beijing. The track "Snow Dragon" built here is the 17th bobsleigh track in the world, the 3rd in Asia and the 1st in China. The Yanqing Competition Area, where it is located, is one of the competition areas with the shortest construction period, the greatest construction difficulty and the highest construction standards in the history of the construction of Winter Olympic venues.
After five years, in Haituoshan, a "four noes" mountainous area that once had no roads, no water, no electricity and no communication, China's first alpine ski track that meets olympic standards and the first bobsleigh track have been built. At the same time, the Yanqing Competition Area combines the construction of Olympic venues with the promotion of ecological civilization construction, and strives to make the venues and supporting facilities harmoniously integrate with the natural landscape of Xiaohaituo Mountain: by the end of last year, a total of 313 trees were protected in situ in the competition area, 24,272 trees were transplanted from the site, and nearly 300 acres of ex-situ protection bases were built.
It is understood that Yanqing District is actively exploring the "Ice and Snow Experience +" model to promote the linkage development of ecology, tourism, events, culture, education, science and technology and other industries, enrich the supply of winter cultural tourism products after the "Winter Olympics", and enhance the ice and snow consumption experience.
