– The system of mats (tubes) base of the ice arena. – Refrigerant () – the working fluid refrigeration system. Refrigeration unit (chiller) for the rink 60h30 m weighs about 9 -10 tons (length 10-12 m, width of 2.5 m). Installed on a concrete base or a flat, sturdy construction. Automatic Control Panel refrigeration unit (chiller), based on a microprocessor and an electric (power) panel (chiller 300 tons: 380V/50Hz/3 ') Connection of tubing (mats) to the rink pipes feed refrigerant from the refrigeration unit (on the photo – a seasonal ice rink) for the system of the ice arena should be about 8-9 tons of refrigerant (32-40% solution of ethylene glycol) system is a seasonal rink mats, prepared to fill. In steady-state Ice Hockey rink basics design may be such as shown in Figure 1 (on a concrete base) or the same as shown in Figure 2 (a sand-based).

The absence of a concrete foundation (Fig. 2) significantly reduces the overall cost of the project to build the ice arena, while not reducing the quality of the ice arena and the operational capabilities of life. Figure 1 Figure 2 The cooling unit cools the solution of ethylene glycol in the system to temperature of -9 . Chemical structure of the solution of refrigerant does not allow it to freeze and crystallize. Technical Support Personnel work roller, sets the temperature of the refrigeration unit, manually, based on of outdoor temperature and indoor temperature rink. Modern refrigeration systems are equipped with a microprocessor and a system of temperature sensors and air pressure both outside and inside temperature and pressure in the system that lets you manage the entire system rink or semi-automatically, allowing you to control the operation of the refrigeration unit with remote control via mobile phone or pager. To create the ice, the system pumps approximately 9.000 gallons (35 tons) of coolant through the mats and cools the concrete base mat or a skating rink, which is located on the ice surface. Solution refrigerant is pumped (B) in the system of tubes inside the concrete slab on which the ice surface (C). The concrete slab is located between the ice surface (D) and a layer of heat-and moisture-exclusion (E), which allows the ice
