National Speed Skating Oval, the "Ice Ribbon" laid the first stake.

After 1095 days and nights

Another landmark building in the Beijing Olympic Winter Games has completed its first ice making.

Formally have the conditions to meet the test event.

The reporter entered the venue for the first time with excitement.

Floating Frost Jade Comparing Colors, Same Standards for Photographic Mirrors

Thousands of valleys of cold floating silver, a river of cold soaking jade.

This is a number of poems thrown out by educated colleagues in an instant.

Reporter will only say:

Wow, that's amazing!

"Ice Ribbon" has a total ice surface area of nearly 12000 square meters.

Not only big

And is expected to be the "Fastest Ice Making".

Let the athletes fly in the Winter Olympics.

How did we do that? There's a lot of fastidiousness in it.

First of all,need to be flat!

The horizontal deviation of the ice plate is within 4 mm.

It is rare in the world.

Secondly, be uniform!

The smaller the temperature difference, the more uniform the hardness.

According to the requirements of the International Skating Union

The temperature difference on the ice surface should not exceed 1.5 degrees.

Ice Ribbon: 1.5? No, the temperature difference is too big.

Required 0.5！

Even the water for making ice has a requirement.

The water used at home is not used.

It has to be purified first.

And then mixed with common water according to a certain proportion

Achieve optimum conductivity

Lighting, dehumidification, ventilation and other aspects are also taken into account.

For the athletes to achieve good results.

It really breaks my heart.

Behind the "Fastest Ice Making", of course, the blessing of "Black Technology" is indispensable.

It is more appropriate to say "Green Technology".

Because the whole process of making ice is a capital "Green".

In order to practice the concept of "Green Olympics"

"Ice Ribbon" uses the most environmentally friendly ice-making technology.

[High energy ahead]

Carbon dioxide transcritical direct cooling ice-making technology!

Yes, it's the same carbon dioxide in "Fat Otaku Happy Water"!

As a natural refrigerant

Compared with traditional Freon, etc.

Its ODP (ozone depleting potential) is 0.

Waste heat from the ice-making process will also be recycled.

It means

The carbon emissions of this technology are close to zero.

The reduction in carbon emissions is approximately equal to

Annual carbon emissions of 3,900 vehicles

Or the reduction in carbon emissions from planting 1.2 million trees

Because of the large area of "Ice Ribbon"

Can not directly apply foreign technology

Means the development of a new system.

There is no precedent to follow.

What to do?

The answer of "Ice Ribbon" is: Dare to be the first in the world!

Through scientific and technological research

The National Speed Skating Oval has not only become

The World's First Winter Olympic Speed Skating Stadium Using Carbon Dioxide Ice Making

And in two of the most critical design options

The integrated design of the ice-making system and the structural design of the ice plate have obtained utility model patents.

The "China Solution" of this technology was put forward.

After Beijing Olympic Winter Games, the "Ice Ribbon" will be open to the public.

Make ice according to different projects, regions and standards.

It can receive more than 2000 citizens at the same time.

Ice hockey, speed skating, figure skating, curling and other sports

First, watch the world's top players compete for gold and silver in the Winter Olympics.

And then go to the same venue to participate in ice sports.

Rounding up, you and I are Olympic champions.

Let's go! See you at Ice Ribbon!

Looking back on the construction of "Ice Ribbon", Song Jiafeng, executive vice president of National Speed Skating Oval Company, said:

"I think it's difficult for sure."

But I think I prefer to see it as a challenge.

And I think the builders of the Winter Olympics are also willing to meet this challenge.

"Everyone is amazing."

To the builders of the Winter Olympics

The champion behind the scenes

Salute
