1 . In January, 2021, the ice-making work on the ”Ice Ribbon“, a landmark venue for the Beijing Winter Olympics, was completed.
In the Winter Olympics, where races can be won or lost by a small time gap, tiny imperfections in the ice can make all the differences. ”It’s not just a hunk of ice like you’d normally think of, like ice cubes sitting in your freezer,“ told Kenneth Golden, a U. S. mathematician who studies the structures of ice. ”It’s a much more fascinating and complex substance than people would normally think.“
The first step for building any ice rink is to purify the water to remove dissolved solids like salts and minerals. Such impurities don’t fit in the regular hexagonal(六边形的)structure of ice that forms as water freezes. The purer the water, the more consistent the ice surface.
In addition to the need for excellence in the raw materials of ice-making, technology is also very important, As one of the most advanced technologies for winter sports venues, a carbon dioxide cooling technology has been applied on a large scale for the Beijing Winter Olympic Games. CO2 , is not new when it comes to ice-making. However, it has been gradually replaced by the man-made refrigerant, like Freon.
With increasing attention toward climate change, the old refrigerant has come into use again. As an element of the atmosphere, CO2, doesn’t damage the ozone layer. Although CO2 is a greenhouse gas, its greenhouse effect is much lower than that of other synthetic refrigerants. The Winter Olympics venues adopted CO2 instead of Freon as a refrigerant in ice-making, which will reduce carbon dioxide emissions greatly.
”We believe these technological innovations will bring Beijing 2022 to spectators all over the world in a more impressive way.“ told Gao Bo from the Media Operations Department of the Beijing Organizing Committee for the 2022 Olympic and Paralympic Winter Games.

Having won the bid for the 2022 Olympic Winter Games on July 31, 2015, Beijing is set to become the first city in the world to have hosted both the summer and winter editions of the Olympic Games.
With a vision of “Joyful Rendezvous upon Pure Ice and Snow”, Beijing 2022 Olympic Winter Games will build on the legacies of the landmark Beijing 2008 Olympic Games and expects to encourage millions of people across China to embrace winter sports.
The 109 events in seven Olympic winter sports will be held in the three competition zones of central Beijing, Yanqing and Zhangjiakou.
Three Competition Zones
Beijing will host all the ice events (curling, ice hockey and skating) and four snow events, making full use of the legacy venues of Beijing 2008 in the spirit of Olympic Agenda 2020.
Yanqing, a suburban district of Beijing (80km to the northwest) and home to the famous Badaling and Juyongguan stretches of the Great Wall, is to host the alpine skiing and sliding events.
Zhangjiakou, further to the northwest in the neighboring Hebei province, will host all the other snow events in its Chongli district, a popular skiing destination.
Seven new events
The addition of seven new events—women’s monobob, freestyle skiing big air (men’s and women’s) and mixed team events in short track speed skating team relay, ski jumping. Freestyle skiing aerials and snowboard cross-to Beijing 2022’s sports programme will bring about the most gender-balanced Winter Olympic Games to date, with more female athletes (45.44 percent) and women’s events than at any previous Games.
Spring Festival (Chinese New Year)
2022 Olympic Winter Games will take place in February 2022, coinciding with the Chinese New Year, the most important holiday in China.
