Heat-insulated storage container and method for designing a heat-insulated storage container

Abstract

A storage container and a method for designing same, including a wall that forms the storage container and has an inner face and an outer face, and an insulation layer that rests against the outer face of the wall, encloses the storage container and has different thicknesses in different regions of the wall. The insulation layer is thicker in a region that has an above-average temperature difference between the inner face and the outer face of the wall than in a region that has a smaller temperature difference between the inner face and the outer face of the wall.

1 : A heat-insulated storage container, comprising a wall ( 1 ) that forms the storage container and has an inner face and an outer face, and an insulation layer ( 2 ) that rests against the outer face of the wall ( 1 ), encloses the storage container and is configured to have different thicknesses on different regions ( 1 . 1 ,  1 . 2 ) of the wall ( 1 ),
 wherein   the insulation layer ( 2 ) is configured to be thicker on a region ( 1 . 1 ) that has an above-average sized temperature difference between the inner face and the outer face of the wall ( 1 ) than on a region ( 1 . 2 ) that has a smaller temperature difference between the inner face and the outer face of the wall ( 1 ).   
     
     
         2 : The heat-insulated storage container according to  claim 1 ,
 wherein   the wall ( 1 ) is configured to be curved in a concave manner on the outside and correspondingly curved in a convex manner on the inside on the region ( 1 . 1 ) that has an above-average sized temperature difference, in order to receive the thicker insulation layer ( 2 ).   
     
     
         3 : The heat-insulated storage container according to  claim 1 ,
 wherein   the wall ( 1 ) is configured to be curved on a region ( 1 . 3 ) that has a container internal pressure of above-average size, in order to increase the pressure stability of the storage container.   
     
     
         4 : The heat-insulated storage container according to  claim 1 ,
 wherein   the insulation layer ( 2 ) enclosing the storage container has a cuboidal shape.   
     
     
         5 : The heat-insulated storage container according to  claim 1 ,
 wherein   this storage container is arranged in a housing of a heat pump, in particular a heat pump provided for installation in the interior of a building.   
     
     
         6 : The heat-insulated storage container according to  claim 1 ,
 wherein   this storage container is configured as a defrosting buffer of a heat pump.   
     
     
         7 : The heat-insulated storage container according to  claim 1 ,
 wherein   the insulation layer ( 2 ) is configured to be thicker on the region ( 1 . 1 ) on which the inner face of the wall ( 1 ) is particularly cold relative to other regions ( 1 . 2 ) and colder than the outer face of the wall ( 1 ) during the operation of the storage container.   
     
     
         8 : A method for designing a heat-insulated storage container, in which a thickness of an insulation layer ( 2 ) that rests against a wall ( 1 ) of the storage container, that has an inner face and an outer face, and encloses the storage container is specified,
 wherein   a region ( 1 . 1 ) of the wall ( 1 ) that has an above-average sized temperature difference between the inner face and the outer face of the wall ( 1 ) during the operation of the storage container is determined, and a greater thickness of the insulation layer ( 2 ) is specified on the determined region ( 1 . 1 ) than on any other region ( 1 . 2 ) of the wall ( 1 ).   
     
     
         9 : The method according to  claim 8 ,
 wherein   a region ( 1 . 3 ) of the wall ( 1 ) that has a container internal pressure of above-average size is deter-mined and is configured to be curved in order to avoid a deformation.   
     
     
         10 : The method according to  claim 8 ,
 wherein   a mode of operation of the storage container is selected in which the inner face of the wall ( 1 ) is colder than the outer face of the wall ( 1 ), in order to determine the above-average sized temperature difference on a region ( 1 . 1 ).
