Description

Introduction The invention relates to a device for the temporary cooling of goods with - a heat-insulating covering that at least partially encloses a storage room, - a supporting structure for supporting the encasing, wherein the supporting structure transfers weight forces of the encasing and itself into a ground, - a shelving system for placement in the storage room, wherein the shelving system has a plurality of shelves on which the goods to be cooled can be placed, and - a cooling device for generating cooled gas and for cooling the storage room. Furthermore, the invention relates to a method for constructing a device for the temporary cooling of goods, comprising the following steps: a) Erecting a supporting structure to support a heat-insulating covering, wherein the weight forces of the covering and itself can be transferred into the ground by means of the supporting structure, b) Positioning the enclosure on the supporting structure so that a storage space is at least partially enclosed by the enclosure, c) Arranging a racking system in the storage room or erecting the supporting structure according to step a) and attaching the covering around the racking system according to step b), d) Connecting a cooling device to the storage room and commissioning the cooling device to generate and introduce cooled air into the interior for cooling purposes. State of the art Devices for cooling goods, such as food, are well-known and are required during the cleaning, repair, or maintenance of stationary refrigerated shelves or chests in supermarkets or discount food stores to keep the food inside chilled and prevent an interruption of the cold chain. For this purpose, the food is temporarily placed in the mobile cooling device and kept cool there. Once the cleaning, repair, or maintenance of the stationary refrigerated shelf is complete, the food can be removed from the temporary cooling device and returned to the original refrigerated shelf. Such a mobile cooling device is assumed to be, for example, from the DE 10 2016 113 728 B4 The cooling unit features a flexible hood that defines an interior space, a cold air generator, and an air supply duct. The goods to be cooled, particularly food, are removed from the stationary refrigerated display case and stacked on a pallet inside the hood. Above the pallet, within the hood, is the air supply duct with openings distributed along its length, through which cold air is blown towards the goods. The air supply duct extends approximately the entire length of the hood. The hood and the air supply duct conform to the contours of the food to minimize the volume to be cooled within the space and to avoid dead space. In a lower section of the mobile cooling unit, air is extracted from the interior and returned to the air supply unit. Another cooling device is installed in the US 2012 / 0 096 893 A1 revealed. In the case of terrorist attacks or natural disasters, for example, it may become necessary to recover bodies very quickly to prevent the spread of disease. The in the US 2012 / 0 096 893 A1 The described cooling device can be quickly set up at suitable locations and offers sufficient capacity to ensure adequate cooling performance even in hot climates. The cooling device consists of an enclosure surrounding an interior space and several shelving units arranged within that space. Each shelving unit comprises several shelves, each made up of individual struts spaced apart. A compressor generates cold air, which is introduced into the interior space via an air hose through an inlet opening in the enclosure. The air inside the interior exits through an outlet opening in the enclosure. Air can circulate through the openings between the struts within the interior space, ensuring adequate cooling of the bodies. To prevent the escape of germs from the interior space, the enclosure is designed to be airtight. The enclosure also features a pressure relief valve with a filter, which allows for pressure regulation within the interior space. Alternatively, the cooling device can also be used to cool food at parties or events. For the temporary cooling of goods, quick assembly and disassembly of the mobile unit and the ability to accommodate all goods typically found in the stationary refrigerated display case are particularly desirable. In addition to quick assembly and disassembly, it is also advantageous if the cooling system... The device occupies as little volume as possible in a transport state. Task The invention is based on the objective of providing a device for the temporary cooling of goods and a method for setting up such a device, which enables particularly efficient work, in particular in the sense that the transport volume of the device is reduced and the time required for setting up and dismantling the device is also reduced. Solution Starting from a device of the type described above, this problem is solved according to the invention in that the support structure is
