Abstract

In the method and its devices according to the invention is room air conditioning (cooling, heating, humidification and dehumidification, air cleaning, hygiene, etc.), which is specifically designed for the requirements in storage systems and can be made on this basis to extremely rational conditions.

Description

The method (s) according to the invention and their devices are proposals for the central processing of air for the latent conditioning of the indoor air of closed technical storage systems in accordance with the respective application-specific requirements.

The quality requirements for warehousing goods in industry and commerce are steadily increasing - especially in the field of electronics production, pharmacy, medicine, chemicals, etc., the storage criteria are sometimes a dominant quality feature.

The relevant, specific requirements include the media: cooling / heating / dehumidification / humidification / air purity / hygiene etc. - in each case independently or in combinations.

The problem solutions available from the relevant prior art are based on the installation technology conceived for rooms in buildings (inter alia DIN 1946 ) and can only be used with reservations for technical storage systems with highly complex internal geometry. A significant reservation is the high investment costs, which stand in the way of the realization of this technology. In the case of renunciation based on this, risks in the quality area are often accepted with approval.

With the proposals according to the invention, this problem situation is to be eliminated and make solutions with high efficiency in price and performance available through a system technology designed exclusively for technical storage systems. At most, the investment required for the innovative technology will not stand in the way of customer acceptance. reference numeral

function Description

- Air distribution systems -

The use of conventional room air conditioning (cooling / heating / humidification / dehumidification / air cleaning etc.) in closed technical storage systems ( 1 ) each with two storage areas ( 2 ) and a transport area ( 3 ) - shown in 3 / 4 indicates that the air conditioning unit ( 7 ) in recirculation mode conditioned room air via a supply air duct with air inlet nozzles ( 8th ) the storage system transport area ( 3 ) and via at least one return air duct ( 9 ) the circulating air circulation is produced.

With this classic form of relevant air-conditioning technology, all parameters of the specific requirements in the secondary transport sector ( 3 ) without compromise - insofar fulfilled - the opposite is true for the primary storage areas ( 2 ) - the actual goal of the action.

The storage areas ( 2 ) are due to a variety of shelves ( 5 ) in stacking position with little clearance ( 13 ) largely excluded from the indispensable air circulation. At best, with a considerable increase in the amount of air can be produced by induction effects improvements. Basically technical compromises with irrational effort in terms of investment and operating costs.

• – Die konditionierte Zuluft vom Klimagerät (7) wird über vier Düsenkanäle (10), die spiegelbildlich, vertikal an der Außenseiten rechts und links des Lagersystems (1) positioniert sind, unmittelbar den Lagerbereichen (2) zugeführt (5/6/7). Die Düsen (12) im Düsenkanal (10) sind im Höhenabstand auf den Freiraum (13) zwischen den Regalböden (5) bei maximaler Belegung positioniert. Die horizontale Wurfweite der Düsen (12) ist größer als die maximale Breite des jeweiligen Lagersystems (1) – aus der hieraus resultierenden gegenläufigen Luftströmung ergeben sich Verwirbelungen/Turbulenzen, die letztlich die erforderliche Homogenität herstellen. Derartige Luftführung bewirkt, dass die zugeführten Leistungen primär in den Lagerbereichen (2) wirksam werden und hierdurch im Vergleich zu alternativen Zuluftführungen mit deutlich geringeren Luftmengen identische Ergebnisse erreicht werden. Die Rückluft zum Klimagerät (7) erfolgt über ein Rückluftgitter mit Kanalanschluss (11) in der Oberseite Transportbereich des Lagersystems (1).
• – Weitere technische Problemlösungen mit akzeptabler Funktion und Effizienz sind verfügbar:

With the following suggestions, the problem situation is eliminated by the fact that the room air conditioning - as required - exclusively on the storage areas ( 2 ) is related.

• - The conditioned supply air from the air conditioner ( 7 ) is connected via four nozzle channels ( 10 ), the mirror image, vertically on the outsides on the right and left of the storage system ( 1 ), directly to the storage areas ( 2 ) ( 5 / 6 / 7 ). The nozzles ( 12 ) in the nozzle channel ( 10 ) are at height clearance on the free space ( 13 ) between the shelves ( 5 ) positioned at maximum occupancy. The horizontal throw of the nozzles ( 12 ) is greater than the maximum width of the respective storage system ( 1 ) - resulting from the opposite flow of air turbulence / turbulence, which ultimately produce the required homogeneity. Such air guidance causes the supplied power primarily in the storage areas ( 2 ) and thereby achieve identical results compared to alternative supply air ducts with significantly lower air volumes. The return air to the air conditioner ( 7 ) via a return air grille with duct connection ( 11 ) in the top transport area of the storage system ( 1 ).
• - Other technical solutions with acceptable functionality and efficiency are available:

• When producing a functional group air conditioning with storage system technology

This is a principle conventional air conditioning technology accordingly 3 + 4 used - the identified disadvantages of this technique are compensated by the fact that the storage system component goods transport system ( 6 ) is used for air distribution of the air conditioning technology ( 8th - 9 - 10 ).

features

The goods transport system ( 6 ) is moved in a time factor (3 to 4 times / h) from the rest position via the floor via a time-switching logic from "bottom to top" - in this case the high-speed over the Zulufteinlässe (jet nozzles) ( 8th ) deflected vertical air volumes by about 90 ° and intended horizontal storage areas ( 2 ) and subsequently via the return air duct ( 9 ) of the air conditioner ( 7 sucked).

For this purpose, a circuit can be produced, which assigns the goods transport system 2 to 3 rest positions in different height positions, which are taken in temporary intervals and resolved.

• When using nozzle channels in the transport area ( 3 ) of the storage system ( 1 ) (Fig. 11/12)

On both outer sides of the transport area are inside - or outside of the storage system vertical - at least three - nozzle channels ( 10 ) ( 12 ). The nozzles (circular or slots) are at an angle of about 30 ° to the storage areas ( 2 ). Via at least one return air duct ( 9 ) to the air conditioner ( 7 ) the air circulation is established.

Function:

The storage areas ( 2 ) are supplied as intended by indirectly, with high air velocity supplied supply air quantities.

- Air conditioning technology -

The indoor air requirements of indoor technical storage systems ( 1 ) are varied in practical use and differ z. T. authoritative - z. B. latent cooling or latent heating, etc.

For the realization of this, to be met in the required rationality, specifications is a modular air conditioning ( 14.5 ) ( 12 / 13 ) indispensable and provided.

The modular design of the air conditioner ( 14 ) is divided into two basic modules ( 14.1 + 14.2 ) as well as in variable individual modules ( 14.1 to 14.7 ) - the form-fitting according to the application-specific needs with the base module ( 14.1 ) get connected.

Additional functions are available through components in the return air duct ( 9 ) of the air conditioner ( 7 ) can be used. For this purpose, the hygiene function ( 14.8 ) ( 13 ) by UV sterilization. The latter has a capacity control, which is defined by predeterminable air flow rate - two louvers are provided for this purpose ( 14.7 ) in the bypass of the return air channel ( 7 ).

Another function "overpressure in the storage system" can be produced via two louvers ( 15 ) with servomotor - positioned 1 × in the return air duct ( 7 ) and 1 × in an outdoor air connection. Such overpressure device replaces a possibly required lock in the operating opening.

The dimensioning of the air conditioning technology is directly dependent on the quality of the insulation of all surfaces of the storage system.

Isolation on the insides of the bearing system surfaces is the most rational problem solution with the option of prefabricated components.

All components / components of the air conditioning technology are prefabricated in a quality that ensures assembly by fitters without professional qualifications.
