The cooling system was designed taking into account the space available to the investor. In the absence of rooms and space around the hall, selected units had to be placed on the roof together with tank and pump units.
Maintaining high efficiency and compact size led to the choice of a two-temperature cooling system based on SIREG and BRW units. The separation of temperatures in this case, in addition to the energy efficiency resulting from the use of the freecooler only for cooling the hydraulic units, allowed to locate the cold stores on different levels of the small roof space provided by the investor.
The Sireg type unit provides comfort of water use despite the external location of the entire system.
