What is the national speed skating hall, the iconic venue of Beijing 2020 Winter Olympics?
The National Speed Skating Hall (referred to as "Ice Belt" for short) is located at No.2, Cui Lin Road, near the Olympic Park in Chaoyang District, Beijing. It is the landmark venue of the Beijing main competition area of the 2022 Beijing Winter Olympics and the only newly-built ice competition venue.
The design concept of "ice belt" comes from the combination of ice and speed. These 22 ribbons are like the traces of athletes sliding, symbolizing speed and passion.
Environmental protection technology:
The National Speed Skating Hall is the world's first speed skating hall in the Winter Olympics that uses carbon dioxide transcritical direct cooling ice-making technology. This technology is the most advanced and environmentally friendly ice-making technology in the world at present. The carbon emission value approaches zero, and the energy efficiency of ice-making is greatly improved.
As the ice surface area of the National Speed Skating Hall has reached 6.5438+0.2 million square meters, this ice has become the world's largest multifunctional all-ice surface made of carbon dioxide transcritical direct cooling ice-making technology.
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 stadium. Two key design schemes, the integrated design of ice-making system and the structural design of ice tray, have been patented.
