Description

The invention relates to a walk-in refrigerator for the presentation of refrigerated goods.

It is an object of the invention to allow effective cooling in such a walk-in cold room.

This object is achieved with a cold room, which has the features of claim 1. Furthermore, a kit with the features of claim 13 is proposed to solve the problem. Advantageous embodiments and / or embodiments and / or aspects of the invention will become apparent from the subclaims, the following description and the figures.

A basic walk-in refrigerator for the presentation of refrigerated goods is bounded above by a ceiling, preferably bounded below by a bottom and laterally in a spatial direction by two, for example opposing side walls, of which at least one side wall is provided as Warenpräsentationswandung with at least one through hole , The refrigerated space has at least one merchandise display device accommodating refrigerated goods, which comprises a merchandise display page for presenting the refrigerated goods and is arranged between the sidewalls such that the merchandise display device faces with its merchandise display side the Warenpräsentationswandung and spaced therefrom to form a gap, so that the refrigerated goods of the merchandise display device can be removed via the passage opening from the outside, and between the goods presentation device and the other side wall a desirable space is formed.

With such a cooling space, a presentation of the chilled goods accommodated therein is made possible to the outside, ie to the outside of the cooling space, due to the passage opening of the at least one side wall. Likewise, a removal of the refrigerated goods, for example by a customer, can be made via the passage opening of the side wall. Through the walk-in space, the refrigerator allows refilling with chilled goods in a different way than via the passage opening of the side wall. It is thus to implement a filling with new refrigerated goods or other refrigerated goods, without affecting the goods presentation function and / or the goods removal function of the refrigerator, which is achieved through the passage opening of the at least one side wall.

For closing the passage opening of the side wall or the Warenpräsentationswandung can be provided at least one, preferably a plurality of doors or door elements. The at least one door may be a hinged door or sliding door. In order to maintain the presentation function, the doors have at least one area or section which is transparent, in particular transparent. For example, the at least one door is a glass door.

Furthermore, it is provided that the cooling space has at least one recirculation system. The circulating air system comprises at least one fan, at least one, preferably a plurality or a plurality of air outlet openings and at least one air inlet opening. At least part of the air outlet openings are directed onto the intermediate space in order to blow air, for example cold air and / or cooled air, into the intermediate space by means of the air outlet openings. Furthermore, the air inlet opening is arranged in the region of the accessible space, for example, by means of the blower to suck in a predetermined amount of air from the accessible space.

By the circulating air system, a circulating air movement, in particular a circulating air circulation movement, generated within the cooling space through which the goods presentation device specifically with air, especially cold air and / or cooled air, flows around and / or flows through. It has been shown that cooling of the refrigerated goods accommodated in the presentation device, in particular rapid cooling, is favored by this circulating air movement. It has also been found that the temperature of the refrigerated goods can be kept permanently at the desired temperature level by this circulating air movement.

By the air outlet openings are directed to the gap between the goods presentation side of the goods display device and the through-opening having side wall, the generation of an air curtain is favored, which extends in the region of the gap along the side wall and the opening surface of the passage opening overflows. As a result, any losses caused by the passage opening cooling losses is counteracted. It has been shown overall that an effective measure is taken by the recirculation system to cool the refrigerator and the goods contained therein energy-saving to the desired level and to keep energy-saving permanently at this level.

For example, the goods presentation device has a plurality of compartments arranged vertically one above the other, in particular with each one a shelf for supporting refrigerated goods or at least a part or at least more of the refrigerated goods. For example, at least one of the compartments is continuous, thus forming a passage which extends from the merchandise display side to the opposite side or rear side of the merchandise display device. As a result, a flow through the goods presentation device is favored with air, since the air can flow through the continuous compartment while cooling the refrigerated goods contained therein.

The goods presentation device can be a shelf, in particular shelf system. For example, the goods presentation device is a slide shelf. In this case, at least one of the shelves is inclined obliquely downwards towards the goods presentation side in order to effect or at least to favor slipping of the refrigerated goods on the shelf.

In an embodiment of the cooling space, it is provided that the circulating air system is arranged in the region of the ceiling, so that the air is blown from above into the intermediate space by means of the air outlet openings and the air is sucked in from above from the accessible space by means of the air inlet opening. The arrangement of the circulating air system in the region of the ceiling is to be understood in particular in the manner that the air outlet openings and / or the air inlet opening are arranged in the vicinity of the ceiling. In particular, it is important that the air outlet openings and / or the air inlet opening are arranged such that the air flowing in via the air inlet openings also reaches the chilled goods accommodated in the upper region of the goods presentation device.

In this way, the gravity is used when blowing the air into the gap, since the air flow generated thereby has at least one component which is directed in the downward direction, that is directed towards the bottom of the cooling chamber. This results in advantages in terms of energy consumption of the refrigerator for cooling the refrigerated goods. The arrangement of the air inlet opening in the area of the ceiling takes into account that any heated air rises to the top. In this respect, this measure contributes to achieving a rapid cooling of the refrigerated goods and / or to realize the cooling of the refrigerated goods with high efficiency and thus as energy efficient as possible.

The air outlet openings can be arranged or aligned in different ways. In order to achieve the most uniform possible flow of the refrigerated goods, the air outlet openings should be distributed along the goods presentation page or Warenpräsentationswandung, in particular distributed uniformly. In the same direction aims the measure, according to which additionally or alternatively, the air outlet openings are arranged one behind the other in a direction along the goods presentation page or Warenpräsentationswandung. For this purpose, the air outlet openings are arranged one behind the other in a row according to a possible embodiment. According to another embodiment, the air outlet openings may be arranged in each case lying behind one another in at least two rows and the air outlet openings of one row and the air outlet openings of the other row alternate or alternate.

In a further embodiment of the cooling space, it is provided that at least a part of the air outlet openings, in particular at least one or one of the air outlet openings, are associated with a common air duct and at least one of the air outlet openings is formed by a flow outlet of a nozzle connected to the air duct nozzle tube. For example, the air duct is a supply air duct, via which the air flows to the air outlet openings or the nozzle tube. The nozzle tube itself is provided with a nozzle function, by means of which there is an increase in the flow velocity of the air flowing through the nozzle tube. By the nozzle tube thus the circulating air movement is supported for cooling the refrigerated goods.

It can be provided that the nozzle tube protrudes into the air channel with a portion having a flow inlet and in particular can be rotated relative to the air channel. It is advisable that the flow inlet has an inlet surface, which is present in a starting position at least partially transverse to the longitudinal axis of the air channel or has a direction transverse to the longitudinal axis of the air passage direction component and from the starting position, for example by rotation of the nozzle tube relative to the air duct can be moved out.

Thereby, the strength of the nozzle effect of the nozzle tube can be adjusted selectively by the nozzle tube is moved more or less or not at all out of the starting position relative to the air duct. The more, for example, the nozzle tube is moved out of the starting position relative to the air duct, the less the nozzle tube is detected by the air flow of the air channel. If a plurality of such nozzle tubes are provided, by adjusting the respective nozzle effect, the nozzle tubes can be matched to one another with regard to the air flowing out of them in the desired manner. The recirculation through the air circulation system can thereby individually and flexibly to the requirements within of the refrigerator for cooling the refrigerated goods are tuned and adjusted.

The projecting into the air passage portion of the nozzle tube may have or consist of a pipe bend. For example, the pipe bend is a 90 degree bend. For example, the nozzle tube is round in cross-section, in particular circular. In principle, the nozzle tube can also have a polygonal, for example, polygonal cross-section. The air duct may be made of plastic or plastic. Also, the nozzle tube may be made of plastic or plastic. The air duct and / or the nozzle tube may comprise or consist of a thermoplastic, such as PPE.

For this purpose, the respective channel section can have an insertion receptacle at one end and an insertion element for insertion into the insertion receptacle at another end or can be designed accordingly.

According to a possible embodiment of the cooling space, a heat exchanger connected in flow with the circulating air system is provided by which heat is withdrawn from an outside air stream and / or the air stream sucked in via the air inlet opening and then supplied to the air outlet openings as a cold air stream or cooled air stream. As a result, a cooling operation of the refrigerator is favored. It is provided in particular that the heat exchanger is arranged outside the cooling space, for example, is arranged on the ceiling or in the region of one of the side walls. As a result, a cooling operation of the cooling space is made possible, which counteracts condensation. It can be saved measures for condensate drainage or can be realized at least to a lesser extent.

The term "outside air" is to be understood in particular as meaning the air present outside the cooling space, which air is or can be supplied to the heat exchanger as air flow. This outside air can be the air of a sales room, for example a supermarket. Also, the outside air may be air taken from the outside. Due to the circulating air system, the air flowing out of the air outlet openings can originate from the suction via the air inlet opening or the air flowing out of the air outlet openings can originate from an external source or the combination of both variants is possible. The heat exchanger removes heat from this air, so that the desired cold air flows out of the air outlet openings.

One possible embodiment is that the heat exchanger is a part of a cooling unit, in particular a plug-in cooling unit. As a result, the refrigerator can be equipped in a technically simple manner with a cooling, since it can be used on already available on the market prefabricated refrigeration units.
