Secrets of high-speed ice: preparing the hockey arena for competition

Despite the fact that the speed of installation of engineering systems and construction of building structures of ice arenas is impressive even for specialists, after the completion of the main works, the staff do not have to rest on their laurels. The formation of ice cover itself is a complex multi-stage process.

Ice laying process

On the technology of freezing on the example of the preparation of the hockey arena, we were told by the engineers of the design and construction company Proxima, which in the last 10 years created more than 50 top-class specialized objects in Russia.

Slow rising fast ice

You can get acquainted with the typology of ice fields, types of necessary engineering communications and machines on the site procsima.com. Within the framework of this article, we will tell you how and what 50 tons of special purified water are spent before putting the object into operation.

There is such a concept - the optimal coating thickness.Exceeding the standard is fraught with a decrease in the quality of the upper layer: refrigeration equipment may not cope with maintaining the required temperature (from -3 ° C to -5 ° C) due to the fact that the air temperature is positive. Thin ice is dangerous the formation of through cracks.

Ice fill layers

On professional arenas they try to “manage” the inch thickness of the finished ice (about 25 mm), provided that the top layer is constantly updated.

Special combines for pouring coating spray water in a state of fine mist. This creates the first two layers, each one less than 1 mm thick. Then a layer of water mixed with a white dye is applied. Without it, the ice would look gray. In addition to being not aesthetically pleasing, from a functional point of view, the visual contrast between the surface and the puck would be insufficient.

The third sprayed layer is slightly thicker - about 1.5 mm. A marking of the site, club logos and advertising images is applied on top of it. Then the final 8 to 10 layers of ice are formed, but this work is already done with the help of machines of another type.

It is believed that the less water is frozen at each of these stages,the higher the final quality of all the work carried out.

Temperature: good and bad ice

Figure skating and hockey have different requirements for coating temperature. In order to get an effective repulsion for jumping, you need a "soft" platform with the temperature of the upper layer not lower than -3 ° C. Hockey players will crush such ice in a few minutes of the game. But below -5 ° C to cool the arena does not make sense, since the fragility of the coating increases, and it becomes prone to the formation of deep cracks and breaking off large pieces.

Thus, engineering communications of sports facilities should support operating modes in very narrow ranges. Moreover, coordinated work is required for both refrigeration systems and equipment for air conditioning and drying air in the room.
