Description

Anordning for uppvarmning av en markyta medelst en rtircirkulationskrets Rireliggande uppfirming avser en anordning for uppvarmning av en markyta fiiretradesvis en fotbollsplan med hjalp av ett i en rordragning strommande transport-medium. Harigenom erhalles ett mycket billigt och effektivt sat att exempelvis en fotbollsplan aft kunna anvandas aven under kalla fOrhallanden strax fore eller efter en vinterperiod. The present invention relates to a device for heating a ground surface, preferably a football field with the aid of a transport medium flowing in a pipe drawing. This results in a very cheap and efficient way that, for example, a football pitch can be used even during cold conditions just before or after a winter period.

Ett syfte med foreliggande uppfinning är aft astadkomma anordning fdor uppvarmning av exempelvis fotbollsplaner, sa aft dessa kan anvandas en langre tid under aret. De for uppfinningen utmarkande sardragen firms angivna i efterfOljande patentkrav. An object of the present invention is to provide a device for heating, for example, football pitches, so that these can be used for a longer period of time during the year. The features of the invention are set forth in the appended claims.

Tack vare uppfinningen liar man nu astadkommit en anordning, som pa ett utmarkt satt uppfyller sift syfte samtidigt som den dessutom är bade billig och Ian aft tillverka. Genom den rdrcirkulationskrets som innefattas i anordningen enligt uppfinningen kan man varma upp en markyta genom art ta vara pa den varme som finns nere i jorden och transportera upp denna till markytan med riireirkulationskretsen enligt uppfinningen. Genom aft tidigt pa sommaren och hela den varma perioden utnyttja den varma ytjordvarmen aft Was ner till lagsta gravda slangposition i marken uppvarms och accumuleras jordmassan runt derma slangpossition och kan tillsammans med den naturliga jordvarmen anvandas till uppvarmning av ytor vintertid och genom aft fiirlagga de varme hamtande slangama sidoforskjutna de varmeavgivande slangarna, sett fran ovan, och sammanbundna till ett slutet system, kan stone varmeupptagningsomrade erhallas. Thanks to the invention, a device has now been provided which in an excellent way fulfills its purpose, while at the same time it is both cheap and easy to manufacture. Through the tube circulation circuit included in the device according to the invention, it is possible to heat a ground surface by taking advantage of the heat present in the earth and transporting it up to the ground surface with the tube circulation circuit according to the invention. Through the early summer and the whole warm period, use the warm surface geothermal heat from Was down to the lowest buried hose position in the ground, the soil mass around this hose position is heated and accumulated and can be used together with the natural geothermal heat to heat surfaces in winter. the hoses laterally displaced by the heat-dissipating hoses, seen from above, and connected to a closed system, stone heat absorption area can be obtained.

Uppfinningen beskrivs narmare nedan med hjalp av foredragna utforingsexempel under hanvisning till bifogade ritningar, pa vilka fig. 1 visar en schematisk vy av en anordning enligt uppfinningen, som Overst ar en sidovy av nagra sarnmankopplade rOrcirkulationskretsar och darunder en vy ovanifran samt slutligen en forstorad delvy fran fig. 2, och 1 fig. 2 visar en schematisk sidovy av hur en rordragning enligt fig. 1 kan se ut langs snitt a-a och av vilken en uppforstorad delvy visas underst i fig. 1. &Isom framgar av fig. 1 och 2 visas har en firsts utfdringsform av uppfinningen vid vilken en anordning 1 är utford aft medelst ett transportmedium 3, exempelvis vatten uppvanna en markniva 7 t.ex en fotbollsplan, vilket medium 3 hamtar vanne nerifran marken vid en varmeniva 9. Anordningen 1 innefattar en rorcirkulationslcrets 4 med en rordragning 5, 6 innehallande namnda transportmedium 3 och vilken omvaxlande fOrloper en fdrsta forutbestamd stracka strax under en markniva 7 som utgor en uppvarmningsyta 8 dar sjalva varmeavlamningen fran transportmediet 3 ager rum och en andra forutbestarnd stracka belagen betydligt under namnda markniva 7 som utgor varmenivan 9 dar transportmediet 3 vans upp av omkringliggande jord och sand 15, vilken krets 4 uppvisar tva andpartier 10 och 11 dar rtirdragningen 5,6 uppvisar en 1800 krokning samt mellan dessa korsningsstallen 12 av rordragningen 5,6 dar derma altemerar fran sin ovre strackning i uppvammingsytan 8 till sin djupare strackning i vannenivan 9. The invention is described in more detail below with the aid of preferred exemplary embodiments with reference to the accompanying drawings, in which Fig. 1 shows a schematic view of a device according to the invention, which is a side view of some interconnected circulating circuits and below a top view and finally an enlarged partial view. Fig. 2, and Fig. 2 shows a schematic side view of what a pipe drawing according to Fig. 1 can look like along section aa and of which an enlarged partial view is shown at the bottom of Fig. 1. & As can be seen from Figs. 1 and 2, a first embodiment of the invention in which a device 1 is challenged by means of a transport medium 3, for example water, to obtain a ground level 7, for example a football pitch, which medium 3 retrieves water from the ground at a heating level 9. The device 1 comprises a rudder circulation circuit 4 with a rudder 5, 6 containing said transport medium 3 and which alternately runs a first predetermined distance just below a ground level 7 which constitutes a u heating surface 8 where the actual heat dissipation from the transport medium 3 takes place and a second pre-existing stretch significantly below the said ground level 7 which constitutes the heating level 9 where the transport medium 3 is raised by surrounding soil and sand 15, which circuit 4 has two duct portions 10 and 11 where the traction 5, 6 has a 1800 hook and between these crossing stalls 12 of the pipe drawing 5,6 where it alternates from its upper stretch in the heating surface 8 to its deeper stretch in the water level 9.
