Description

FIELD OF THE INVENTION

The invention relates to an insulating structure module and an insulating structure. In particular, but not exclusively, the invention relates to a cold and / or heat retaining insulation structure, for example for sports facilities or storage.

BACKGROUND OF THE INVENTION

10

It is known to use solid insulators as the thermal insulation of the warehouses. As an insulating material, such structures typically use a solid material such as fibrous insulators or solidifying insulating foams.

15 At sports venues, refrigerant for ski pipes and ice rinks is typically distributed through a distribution pipeline located below the floor to be cooled. The refrigerant is pumped through a distribution pipeline using, for example, carbon dioxide or a glycol solution as the flowing refrigerant. Ammonia has been used especially in refrigeration machinery for cold production. 20 Ammonia has the advantage of a better refrigeration factor than other refrigerant alternatives, but the use of ammonia is limited by safety regulations. The use of carbon dioxide in an enclosed space also always requires consideration of safety aspects. As a heavier gas than air, carbon dioxide sinks downwards.

o 25 New solutions have been sought to reduce the energy consumption of chilled sports facilities and storage facilities, including the placement of chilled facilities inside the country. According to some calculations, the cooling energy requirement for a x tunnel ski tunnel is reduced

CL

about 25% in 2-3 years compared to the first year because the heat flow from G> o 30 to the tunnel is halved in this time. However, the cost of farms being built deep into the rock and into the soil is high.
