On the morning of January 24, the National Speed Skating Hall completed the ice making work of the speed skating track of the Beijing Winter Olympic Games, waiting for the Winter Olympic athletes to compete bravely. The National Speed Skating Hall is the world's first Winter Olympic speed skating venue using carbon dioxide transcritical direct cold ice, and it is also the largest carbon dioxide transcritical direct cold ice making system in China. The system can not only take into account the green and energy-saving requirements, but also make the ice surface temperature uniform, to ensure that the ice surface temperature difference does not exceed 0.5 °C, which is conducive to athletes to create better results.

For more information, stay tuned to the Winter Olympics.
