Ice skating is one of the most enjoyed sports around the world. When doing this exercise on natural ice, either an appropriately sized outdoor or indoor link should be provided. The construction and management of outdoor links depends on moody weather and such links cannot be used in warm climates or in warm seasons. Indoor links using natural ice, on the other hand, must be equipped with a centralized cooling system to keep the ice surface at an appropriate temperature and to prevent the ice from melting. Ice skating rinks made of natural ice, whether outdoors or indoors, should be resurfaced periodically to maintain a smooth ice surface and enough to skate. Such resurfacing typically consists of an expensive self-propelled ice surface retouching device, often referred to as a Zamboni device.

Artificial ice links have a number of advantages over natural ice links as shown in the following table.

Table 1

division Natural Ice Link Artificial Ice Link Constraints  There are many restrictions on the environment such as climate.  It is hardly affected by the environment such as climate, so it can be easily installed and used inside and outside. maintain  Maintenance cost is high (I need ice management using jam bonnie)  Low maintenance costs. link  Use is limited.  It can be used for multipurpose purposes. Ice  Depending on the weather conditions, after about three hours the ice will fall below 80%.  80% to 90% retention for 10 years. Mobility   It is fixed.  Regardless of place (free movement and installation possible) Facility Management  Aging of equipment due to moisture and moisture.  Deterioration and delay of equipment due to lack of moisture and moisture. Profitability  Expensive maintenance fee.  Management cost and facility cost reduction effect.

As shown in Table 1 above, the natural ice link is fixed and cannot be moved once constructed, whereas the artificial ice link has the advantage of being easily installed anywhere and convenient to move and install as needed. It boasts excellent ice quality and its semi-permanent lifespan, which is incomparable with conventional ice rinks.

Natural ice link suffers from financial deficits due to huge investment costs and maintenance costs such as ice machines and electric charges, but artificial ice link can be maximized at a low cost because it rarely costs maintenance, maintenance and management. It is an economical product that solves the shortcomings of natural ice rink that the ice does not freeze due to fluctuating fluctuations or the ice sheet is easy to fall due to snow or rain.
