entire length of the Kiihliaöfoels the same. However, it would be desirable to keep several compartments next to each other at different temperatures in one and the same refrigeration cabinet. It would be conceivable to divide the refrigeration unit into several adjacent compartments by means of vertical partition walls and to set and maintain different temperatures in these compartments by means of different air speeds. The temperature could then be changed by changing from one air speed to another therefore practically not

because the airworthiness in all parts must be adjusted to a certain value. Beia lowering the LuftgeseSwiadigkeit different Nadhteile occur, particularly check forms too low at

a vertical stratification of different zones across each other. However, it is desirable that all refrigerated compartments are located one above the other in one compartment be kept at the same temperature

It would be possible to selectively set temperatures in the individual adjacent a Compartmenting of a piece of refrigerated furniture by making each 'compartment' separate cooling unit is assigned. Through this it ^ hohts However, the technical effort and thus the price of the refrigerated cabinet are considerable.

In contrast, the invention is based on the object " a refrigeration unit with several side by side Create departments that are either on the same or can be set to different temperatures, with all compartments of only one cooling unit with only one Thermostat can be cooled and the air speed

nearly
/ is in all compartments the same * This object is achieved according to the invention in 'that the refrigeration units is divided into at least two juxtaposed compartments with separate air circulation, and in that an adjustable baffle is provided in each compartment, the 3® on the position of the the The air flow flowing into the heat sink branches off and is combined with the air cooled by it behind the heat sink.

In such a refrigeration unit in a compartment with the same temperature in the near-next compartment, to go over to a higher or lower temperature It is possible to change the operating status of the refrigeration unit and the air speed, in general, for each compartment a continuous control of the temperature between a minimum and a maximum value depending on the temperature in the feasible compartments.

The guiding device is twofold as a slide plate formed, by shifting a path for the branched off partial flow opened and at the same time the den Airflow sweeping through the heat sink is throttled. Herewith the flow resistance is easily kept the same for every position of the guide device »see above that the air speed also remains unchanged

In a further embodiment of the invention, the guide device is designed in such a way that it is in its end position in a manner known per se from. d © r from the heat sink flowing "cold air branches off a portion and snap Bingangsseit © heatsink & tax * fiefefühs" t · In this Endstoliwsig the Leit "device will a © ice certain proportion dew carbonated Lwüt SKr YorktjMlmag the back flowing from the refrigeration units the heatsink air used.

Further advantages and features of the invention result from »see from the description of an exemplary embodiment © based on the Drawing·

Figs. 1 and 2 soap a queue, you eh. a compartment of the established & measured refrigerated shelf »where see the head of the department 'different positions are located *

The refrigerated shelf has a cabinet-like housing, which from the front 1 is accessible. About the interior of the The shelf is divided into two or more by vertical partitions la

adjacent compartments divided. Each compartment is divided into individual cooling compartments by intermediate floors 2. The cooling body 3 is located on the bottom of the cooling shelf and extends uniformly through all compartments over the entire length of the cooling shelf. Pie cold air flows from the heat sink 3 between the rear wall 4 of the Kühlregal® and a "perforated partition S upwards" parallel to it. The cooling air is distributed over the individual cooling compartments. The cooling air is mau deflected downward at the front side mixed with Deia v © j above kosaaenden airflow, s © © * ice that check veil-like »by usiten directed airflow: forms. This circulation is generated by the ventilator β, which sucks in the air from above and pushes it through the heat sink 3.

According to the invention is tight Wset? the heat sink 3 formed a kind of raised floor. The upper plate of this raised floor leaves a slot for the sucked in air on the audience side and a slot for the rising cold air on the back. The lower base plate is divided into a sliding plate 7 located directly above the heat sink 3 and a fixed plate 8. The fan 6 is inserted into an opening in the stationary plate δ. A® bar 9 extends between the lower and upper floor panels.

The sliding plate 7 is in a position in which it rests with its right edge against the left edge of the fixed plate 8, in the direction of the rear wall 4.

push. A gap 10 opens in the direction of flow in front of the heat sink 3, while the gap 11 between the rear wall 4 and the heat sink 3 narrows Walk through the intermediate floor without being cooled. The cooled and the uncooled air mix in the shaft asi of the rear wall 4t so that the overall temperature in the refrigerated shelf is higher.

The upper base plate 12 has a section 12a of greater thickness and a section 12b of smaller thickness, the top of both sections being at the same height * The strip 9 between the upper plate and the ustter plate is located outside the chest of the refrigerated shelf. Therefore, the upper B © «ä © © saplafct 12 is in the one position (Fig.l) with their portion 12a of greater thickness on the upper edge uer d®r bar 9. This separates the suction side of the fan from the rear side. If, on the other hand, the upper base plate is laid turned by 18 °, the section 12b of the smaller bead is above the strip 9, so that the cross-flow cross-section above the strip 9 remains free (see FIG. 2). In the same position, the Sehiebeplatt © 7 is shifted to its right © end position, so that the Selilits 10 gsscSilossea lsi in this position becomes a feil d®rv®m heat sink

Cold air is branched off and guided between the inlet side of the heat sink. In this partial flow, the air is pre-cooled to the heat sink, so that there is a lower temperature overall at its exit end and thus a lower temperature is set in the cooling shelf.

Further © advantageous cooling properties result from the fact that the Äfesehnitt 12a has a larger seal, so cüafö <äl & base plate In larger ^ sad eiaea Afesöhnitt geriagöres *

You Hh & p the isolated section 12a stored goods, however, is not affected by hes down "by the warmer air.
