Ice production using carbon dioxide transcritical direct refrigeration.
The National Speed ??Skating Stadium ("Ice Ribbon"), located at No. 2 Lincui Road, Chaoyang District, Beijing, near the Olympic Park, is the iconic venue and the only newly built ice venue for the 2022 Beijing Winter Olympics in the main competition area of ??Beijing. Competition venues.
The design concept of "Ice Ribbons" comes from an idea that combines ice and speed. The 22 ribbons are like the traces of athletes skating, symbolizing speed and passion.
Environmental protection technology:
The National Speed ??Skating Stadium is the first Winter Olympics speed skating venue in the world to use carbon dioxide transcritical direct cooling ice making technology. This technology is currently 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.
Since the ice surface area of ??the National Speed ??Skating Hall reaches 12,000 square meters, this ice has become the world’s largest multi-functional full ice surface using carbon dioxide transcritical direct cooling ice making technology.
After the game, the ice surface can be refrigerated by zones, and the temperature of each piece of ice can be controlled individually to achieve "simultaneous operation and different use" of the venue. Two key design solutions, the integrated design of the venue's ice-making system and the ice plate structural design, have been patented.
