Cover Intended for a Pool Unit within a Pool System

Abstract

The present invention relates to a cover ( 10 ) intended for a pool system ( 1 ), the cover being lightly flexible and formed as a pool-covering structure and serving as a protection, where said cover ( 10 ) is adapted to cooperate in edge-related fashion with a guide arrangement ( 11 ) or similar means, said cover ( 10 ) being oriented by support means ( 112 ) at a predetermined distance from the upper surface of a body of liquid or body of water enclosed by the pool. Said cover is integrally formed with and/or adapted to support liquid-Tillable or liquid-filled channels ( 14, 14 a ) where said channels are adapted to be included in one or more thermal energy absorbing units ( 6 a ) included in one or more suntrap apparatuses ( 6 ). A liquid in these liquid-filled channels ( 14 ), heated by solar energy, is adapted to be heat exchanged with said body of liquid or body of water ( 2 ) enclosed by the pool.

         10 . A cover arrangement intended for a pool system, being lightly flexible and formed as a structure, covering a pool and serving as a protection, where said cover is adapted to be able to assume a first end position, covering the pool unit or pool, and a second end position exposing the pool unit or pool, and where necessary every interjacent position, in that said cover is adapted to cooperate, in an edge-related fashion with a guide arrangement or similar means, said cover being oriented, by supporting means, at a predetermined distance from the upper surface of a body of liquid or body of water enclosed by the pool, characterized in that said cover is integrally formed with and/or adapted to support liquid-fillable or liquid-filled channels, that said channels are adapted to be included in one or more thermal energy absorbing or radiating units, included in one or more suntrap apparatuses, and that a liquid, heated by solar energy in liquid-filled channels, is adapted to be heat exchanged with said body of liquid or water enclosed in the pool. 
     
     
         11 . A cover arrangement as claimed in  claim 10 , characterized in that said liquid-filled channels are, within a number of thermal energy absorbing units, integrally structured between two or more lightly flexible sheet strata. 
     
     
         12 . A cover arrangement as claimed in  claim 10 , characterized in that said liquid-filled channels are applied to the upper side of a sheet stratum, forming the cover within thermal energy absorbing or radiating units. 
     
     
         13 . A cover arrangement as claimed in  claim 10 , characterized in that sheet supporting or bearing means extend between guides associated with a guide arrangement. 
     
     
         14 . The cover arrangement as claimed in  claim 10 , characterized in that a pump unit is adapted to supply a liquid, to a heat exchanger, surrounded by the body of liquid enclosed in the pool or direct to the body of liquid enclosed in the pool. 
     
     
         15 . A cover arrangement as claimed in  claim 10 , characterized in that a selective number of carriages are disposed to cooperate with parallel guides included in said guide arrangement, that each sheet supporting means, in the form of a rod or a wire, is adapted to cooperate each with said guide arrangement. 
     
     
         16 . A cover arrangement as claimed in  claim 15 , characterized in that said liquid-filled channels are wholly or partly oriented at right angles to said rods. 
     
     
         17 . A cover arrangement as claimed in  claim 10 , characterized in that one or more thermal energy absorbing units, included in one or more suntrap apparatuses are exposed to thermal insulating air strata oriented on each side of the pool protection and will thereby be subjected substantially to an absorbing thermal radiation and/or sunlight directed towards an upper side. 
     
     
         18 . A cover arrangement as claimed in  claim 10 , characterized in that said units and associated components for the pool protection are structured with heat absorbing surfaces facing upwards and with thermally insulating surfaces facing downwards, for the formation of an upper surface for a safety distance. 
     
     
         19 . A cover arrangement as claimed in  claim 10 , characterized in that the utilized thermal energy absorbing units are oriented so that they may absorb thermal radiation and/or sunlight substantially from above and do not, or insignificantly, permit the absorption of heat from the water surface via thermal conduction. 
     
     
         20 . A cover arrangement as stated in the preamble of  claim 10 , characterized in that said cover being supported along the periphery of said cover above the body of water and above the upper end portion of the pool. 
     
     
         21 . A cover arrangement as stated in  claim 20 , characterized in that at least one energy absorbing unit, related to a suntrap arrangement, is attached to said cover. 
     
     
         22 . A cover arrangement as stated in  claim 20 , characterized in that a cover is formed from a material subject to be rolled or folded up. 
     
     
         23 . A cover arrangement as stated in  claim 20 , characterized in that said cover is supported by one or more pontoons. 
     
     
         24 . A cover arrangement as stated in  claim 23 , characterized in that said pontoons are fillable by compressed gas, especially compressed air. 
     
     
         25 . A cover arrangement as stated in  claim 24 , characterized in that said pontoons are distributed along the surface of water and are adapted to support any predetermined force acting on said cover. 
     
     
         26 . A cover arrangement as stated in  claim 20 , characterized in that said energy absorbing units may be emptied or filled with heat carrier liquid, such as water, and that the process of emptying is to be activated by a rolling up or folding sequence. 
     
     
         27 . A cover arrangement as stated in  claim 10 , characterized in that a reduction of the temperature within said channels is preformed by spraying a thin layer of water over the cover to be subject to evaporation.
