The cost of modern ice rinks can be tens or hundreds of millions of dollars. In the refrigeration unit used to create the ice arena or ice rink used the same principle as a conventional air conditioner or refrigerator. However, the main difference is that the refrigerant () refrigeration system is not in direct contact with water (ice) is no effect on the water / ice directly. Instead, up to sub-zero temperatures cooled a special solution (this may be a solution calcium chloride, propylene glycol, or 32-40% solution dvumolekulyarnogo alcohol – ethylene glycol), which, passing under pressure through a complex system of tubes (the mat – the base rink) allows you to create and maintain the ice in the arena. The system of mats, basic skating rink may be made of steel or plastic tubes. For seasonal rink mat system is usually installed on a sand-based or similar ground-based. In most stationary roller system of pipes (mats rink) is installed on a concrete or sand-based (see below).
The basis of the rink – Ice Arena At some professional arenas to create the most transparent ice is used prepared by de- water, but plain tap water is also well suited for this purpose. For ice rinks open, you can use a river of fresh water, pre-cleaned of sand or other mechanical impurities. The system of the ice arena consists of 4 main elements: – One or more refrigeration (chiller) – The system of pipes to connect the mats to the ice arena refrigeration unit.
