Embodiment Construction

[0040] in the attached figure 1 The container 1 shown in has a container wall 2 in which a vacuum insulation panel 2' is present as thermal insulation. The vacuum insulation panels 2 ′ of the illustrated exemplary embodiment are arranged in a covered manner in the wall 2 and are therefore only indicated by dashed lines. However, reference is made to the prior art described here.

[0041] The container 1 is closable by means of a lid 3 hinged on the container 1 , wherein the lid 3 is shown in an open position in the single illustration of the drawing. The cover 3 also has a thermally insulating insert in the form of a vacuum insulating panel or panels.

[0042] In order to be able to transport temperature-sensitive items 4 in the interior of the container 1 , there is a receiving space 5 in the interior of the container 1 . In the single illustration of the drawing, it is shown with dashed lines how the corresponding object 4 can be located in the receiving space 5 . The ar...

Abstract

The invention relates to a method for preconditioning at least one latent heat storage element (7), which is arranged in a heat-insulated closed container (1) with a receiving chamber for goods to be transported, wherein the latent heat storage Element (7) has a target temperature preferably slightly above 0°C. In this method it is particularly expedient to fill the receiving space of the container (1) with a certain amount of coolant (9), in particular water ice, and to close the container (1) and thereby release the The latent heat storage element (7) cools down to its target temperature.

Description

technical field [0001] The invention relates to a method for preconditioning at least one latent heat storage element. Background technique [0002] When heat is stored in a storage material suitable for this, its temperature generally increases. This form of heat storage is known as sensible or sensible heat storage. [0003] When a phase change occurs in a material suitable for this, such as from a solid phase to a liquid phase (or vice versa), then the difference between the temperature of the storage material and the heat absorbed (or released) by the storage material The relationship is no longer linear. Upon changing from solid to liquid, the thermal storage material begins to melt when the phase transition temperature is reached. With heat delivered, the storage material is maintained at this temperature until the storage material is completely melted. The increase in temperature occurs only afterward with continued heat absorption. [0004] Since no increase in ...
