Outdoor skating doesn't just happen in winter.On August 8, skating lovers can go to the outdoor ice rink of the Olympic Park on the South Bank of Hunhe River to skate the real ice!In order to meet the "National Fitness Day" in Liaoning and Shenyang on August 8, the Liaoning Provincial Sports Bureau and the Shenyang Sports Bureau will launch a series of national fitness activities, of which "Summer snow and ice" is an important item. Ice hockey and figure skaters will perform in the 150 square meter open-air real ice rink.

At the site of the Olympic park ice rink, a large tent covering nearly 200 square meters, with a height of 4 meters, stands in the center of the site, next to it is a giant generator and refrigerating machine.Entering the tent, you can see that there is a smooth ice surface in the center of the baffle.Lou Huichuan, the project leader of Beijing Ouyue ice and snow sports company, who is responsible for casting of the outdoor ice rink, introduces:"It is much more difficult to water an ice rink outdoors in summer than indoors, this several days Shenyang daytime highest temperature at 30 ℃ above, the ground the highest temperature can reach 50-60 ℃, ice-making equipment quality must be up to standard.We first set up a large tent on top of the ice-pouring site to prevent the sun from shining directly on the ice, because outdoor ice should avoid direct sunlight.In addition, the tent also keeps the air above the ice relatively cool.When the players perform on the ice, the curtain around the tent can be lifted up and the audiences can watch from around.When the ice field is not in use, all the curtain will be put down and the ice field will be kept warm."

。In the summer, when making ice outside, the cooling equipment under the ice must be strengthened. According to Lou Huichuan, the ice is poured using the advanced ice making technology of Austria. First, the site is covered with "intelligent pipes", which are called absorption pipes, inside flowed a carrier coolant, used for rapid cooling.The coolant temperature in the absorption tube can be changed from 15 ℃ below zero to 20℃ below zero through the control of the refrigerating machine.After the completion of the intelligent pipeline, the generators, refrigerating machine and water pipes are all connected.The baffle around the site is closed to form a impounding reservoir, and then the bottom ice can be poured.The pump pumps the water into the ice rink, and then the refrigerating machine take 15 ℃ below zero to 20 ℃ below zero coolant through intelligent pipe to the surface.After 48 hours, 2 cm thick ice on the bottom of the ice rink is finished.

After the bottom ice is finished, the ice rink starts to work on the second layers of ice.Lou Huichuan said:Compared with the bottom ice, the second layer of ice surface is much more complicated.In order to achieve the professional competition ice surface effect, The first thing to do is to whiten the bottom ice.It is to spray white paint on the surface of the bottom ice, so that the ice will look very white and beautiful.Then spray the red paint line on the ice.This time in order to meet the Liaoning National Fitness Day, highlight the Liaoning sports elements, the design of the ice rink center is the flag of the Liaoning sports delegation compared with the general competition ice rink.In order to display the logo clearly in the center of the rink, we have adopted the professional painting technology.Now the water on the second layer of ice has been filled and is currently being frozen. It is estimated that it will take another full day."

Shenyang's first summer outdoor ice rink will be open to skating enthusiasts for a period of time after the National Fitness Day on August 8.
