The National Speed Skating Oval has repeatedly set new Olympic records, and we can't help sighing that the "Ice Ribbon" deserves to be called "The fastest ice".

The "Ice" Surface Behind Success

In nature, water will form ice when the temperature is below 0 ℃, but it is not so simple to make ice for the Winter Olympics. It should not only achieve fast formation time and smooth surface, but also meet the different needs of different events for ice temperature, thickness and so on. Speed skating is an ice sport with extremely strict requirements on the ice surface. National Speed Skating Oval is the main venue of this year's Winter Olympics speed skating event. Olympic Committee, adhering to the concept of green Winter Olympics, with the support of the International Olympic Committee and international experts, has held many discussions with well-known experts in the refrigeration industry at home and abroad, abandoned the traditional ice-making method, and adopted carbon dioxide (R744) transcritical direct refrigeration system. Its advantages are high safety, low energy consumption and operation cost, and environmental friendliness. And all the heat can be recycled, which is one of the most promising projects in the energy system of ice venues. It can make the energy system of ice venues run efficiently, and has broad application prospects in the world.
