"Black Technology" Helps Create a Green Winter Olympics
During the construction of the three Winter Olympics venues, low-carbon environmental protection has become the main development direction, and green has become the background color of Beijing Winter Olympics construction.
1, "ice belt" realizes the most environmentally friendly and low-carbon ice surface.
The National Speed Skating Gymnasium "Ice Belt" is the world's first speed skating gymnasium in the Winter Olympics that adopts the ice-making technology of transcritical direct cooling of carbon dioxide. This technology is the most advanced and environmentally friendly ice-making technology in the world. The carbon emission value is close to zero, and the energy efficiency of ice-making is greatly improved. It is understood that after the competition, the ice surface can be refrigerated in different zones, and the temperature of each ice can be controlled separately, so as to realize the "simultaneous operation and different use" of the venues. Two key design schemes, the integrated design of ice-making system and the structural design of ice tray, have been patented.
2. Winter and summer events are converted into venue standards in both directions.
The venues of the 2008 Beijing Olympic Games are widely used in the Beijing Division of the Beijing Winter Olympics to realize the two-way conversion from winter and summer events to standard venues in the Beijing Division. The National Aquatics Center "Water Cube" is the venue for swimming, diving and synchronized swimming in the 2008 Olympic Games. During the 2022 Beijing Winter Olympics, the "Water Cube" will be transformed into the "ice cube" to host curling and wheelchair curling events.
In order to realize the "ice-water conversion", it is necessary to set up a curling track in the swimming pool, and increase the ice function on the basis of maintaining the water function, that is, to build a convertible structure in the middle of the competition hall and install a detachable ice-making system, which is the first time in the history of the Winter Olympics.
