Unter dem Begriff "Warenpräsentationsmöbel" seien Möbel jeglicher Art, die der Präsentation und/oder Lagerung von Waren dienen, insbesondere (Tiefkühl- bzw. Kühl)Regale bzw. -schränke, (Tiefkühl- bzw. Kühl)Truhen, (Tiefkühl- bzw. Kühl)Inseln, (Kühl)Theken, etc., zu verstehen.Under the term "goods presentation furniture" furniture of any kind that the Serve presentation and / or storage of goods, in particular (frozen or Cooling) shelves or cupboards, (freezer or cooling) chests, (freezer or cooling) islands, (Refrigerated) counters, etc. to understand.

Für die Kühlung derartiger Warenpräsentationsmöbel wird die benötigte Kühlluft aus der Umgebung des Warenpräsentationsmöbels angesaugt, mittels dafür vorgesehener Einrichtungen innerhalb des Warenpräsentationsmöbels abgekühlt und in den oder die zu kühlenden Warenräume des Warenpräsentationsmöbels eingeleitet.The cooling air required is used to cool such goods display furniture sucked in the environment of the goods presentation furniture by means of Facilities inside the merchandise display unit cooled and in the or initiated for cooling goods rooms of the goods presentation furniture.

Alternativ oder zusätzlich kann eine sog. "stille Kühlung" vorgesehen werden. Im Falle einer sog. "stillen Kühlung" erfolgt die Kühlung ohne eine Luftumwälzung mittels eines Ventilators. Stattdessen wird die Kühlung mittels in dem Möbelkorpus angeordneter Kühlschlangen und/oder Wärmetauscher bzw. Verdampfer, durch die ein Kältemittel oder eine Sole geleitet wird, realisiert.As an alternative or in addition, so-called "silent cooling" can be provided. In the event of A so-called "silent cooling" takes place without air circulation by means of a cooling system Fan. Instead, the cooling is arranged in the furniture body Cooling coils and / or heat exchangers or evaporators through which a refrigerant or a brine is conducted.

Bisher wird dem Schadstoffanteil in dem Luftstrom, der in das Warenpräsentationsmöbel eintritt bzw. der aus diesem austritt, keine Beachtung geschenkt. Es läßt sich jedoch nicht vermeiden, dass gelegentlich Waren-beispielsweise aufgrund einer vorangegangenen unsachgemäßen Lagerung - auch während der sachgemäßen Lagerung in einem Warenpräsentationsmöbel verderben. Die dabei gebildeten Schadstoffe können über den Kühlluftstrom an die Raumluft abgegeben und u. U. wieder einem anderen Warenpräsentationsmöbel und damit den darin gelagerten Waren zugeführt werden. So far, the proportion of pollutants in the airflow that is in the Product presentation furniture entering or leaving this, no attention given. However, it cannot be avoided that goods occasionally - for example due to previous improper storage - too spoil during proper storage in a merchandise display cabinet. The pollutants formed can be released into the room air via the cooling air flow submitted and u. U. again another product presentation furniture and thus the goods stored therein are fed.

Auch erfolgt bei Warenpräsentationsmöbeln bisher keine Warnung, wenn es zu einer Bildung von Schadstoffen, wie beispielsweise Schimmelpilzen, Sporen oder sonstigen schädlichen Kulturen, im Kühlluftkreislauf des Warenpräsentationsmöbels kommt.So far, no warning has been given for merchandise display furniture if there is a problem Formation of pollutants, such as mold, spores or others harmful cultures, in the cooling air circuit of the goods display unit.
