according to the preamble of the main claim.

Cooling and freshness cells of the type mentioned are generally known and in use and therefore do not require any special printed documentation. The interior of the cells requires temperature monitoring and control, which is done via a temperature sensor connected to the cooling unit. These temperature sensors are usually located in the area next to the interior access. When the cell door is opened, it is inevitable that the warm ambient air flowing in briefly reaches the sensor. This leads to an internal temperature that is displayed too high, at least for a short time, and depending on the connection of the temperature sensor, the cooling unit may start operating unnecessarily. This could not be prevented by a plastic pipe surrounding the temperature sensor that is perforated to allow air to escape*

Temperature sensor in the access area opens a short-term opening! of the access should not at the same time result in a corresponding influence on the temperature sensor"

This object is achieved with a cooling and freshness cell of the type mentioned at the outset according to the innovation by the features stated in the characterizing part of the main claim. Advantageous further developments and practical embodiments are set out in the subclaims.

Thanks to this new design, which is extremely simple to implement, the temperature sensor is no longer exposed in front of the inner surface of the relevant wall part, but sits in the recess, offset against a surge of warm air, which the surge of warm air passes smoothly past without reaching the sensor. The arrangement in a wall recess does make the sensor respond somewhat more slowly, but this is not disadvantageous and is definitely desirable in relation to short-term openings of the cell.

In order to avoid having to make the necessary deformations in the outer skin of the cell or frame wall to form the wall recess, a corresponding opening is simply punched or cut out in the outer skin and the wall recess is inserted into the wall element in the form of a

Fig. 2 shows a longitudinal section through the preferred embodiment of the recess.

The cooling and freshness cell, not shown in its entirety, consists of wall elements 1 filled with heat-insulating foam that enclose the cell interior, with a temperature sensor 3 being arranged on the interior side in the area next to the interior access 2. The wall element 1 shown in Fig. 1 is part of the door frame. As can be seen from Fig. 1, the temperature sensor 3 is arranged in a wall recess U of the inner wall surface 5, with

the depth T of the wall recess *J is larger than the outside diameter of the sensor 3. The thermal recess 4 is designed in the form of a profile piece 6 which is foamed into the wall element 1 and is open towards the cell interior 5', for the arrangement of which the inner wall surface 5 has a correspondingly dimensioned cutout opening. In order to be able to arrange the sensor 3 easily and without problems in the recess 4, as shown, elastic sensor locking elements 7 are provided on the inside of the profile piece 6, which protrude into the profile interior like tongues and at appropriate distances, so that the sensor element can be fixed simply by pressing it into the profile piece 6. In order to avoid having to lead the supply line to the sensor from the outside, the recess H, as can be seen from Fig. 2, is provided with a wall element interior opening 8 through which the passage section 9 of the sensor cable 10 passes.
