[0001] This invention relates to a refrigeration device and a method for assembling the refrigeration device. Background Technology

[0002] According to prior art, such as DE 10 2006 061 083 A1 or EP 4 172 542 A1, a refrigeration device is known, comprising: at least one internal container defining at least one internal space; at least one partition element dividing the at least one internal space into a storage area for storing contents and an evaporator area; and at least one sensor unit including at least one pressure sensor for detecting pressure in the internal space, wherein the at least one sensor unit is arranged in the storage area. Summary of the Invention

[0003] The objective of this invention is, in particular but not limited to, providing a similar refrigeration device that exhibits improved characteristics in terms of operational safety and / or reliability. This objective is achieved according to the invention through features of preferred technical solutions, while advantageous configurations and further improvements of the invention can be derived from alternative technical solutions.

[0004] The present invention is based on a refrigeration device comprising: at least one internal container defining at least one internal space; at least one partition element dividing the at least one internal space into a storage area for storing contents and an evaporator area; and at least one pressure sensor for detecting the pressure of the at least one internal space.

[0005] It is recommended that the at least one pressure sensor be arranged in the evaporator region.

[0006] This configuration advantageously provides high operational safety.

Furthermore, it advantageously provides high protection against environmental factors such as high humidity or sudden temperature fluctuations. Specifically, the effects of fluctuating environmental conditions in the evaporator region of the refrigeration unit are advantageously minimized compared to the housing area. This results in advantageously high reliability for subsequent processing of the detected pressure, as the influence of fluctuating environmental conditions on the detected pressure is advantageously minimized. Additionally, it advantageously provides high component efficiency because food-compatible and / or food-appropriate materials are not necessarily required in the evaporator region, particularly due to the spatial separation between the evaporator and housing areas.
