Abstract

Maintaining a cold chain by arranging a Kälteschleiersystems, characterized in that a Kälteschleiersystems (17) with vertically arranged cooling coil (11) in modular design by horizontal ausblasende cross-flow fans (16) at intended locations (1) are mounted. The modules of the cooling coil (11) can be switched on or off depending on the need for the degree of cold. The cold fogging system (17) can also be used without cooling register (18) only as horizontally generating shielding of the entrances / exits (4) of the respective building.

Description

Fresh produce, refrigerated and frozen goods, frozen food, natural and ice cream, as well as pharmaceutical and cosmetic products, require a closed cold chain during production, storage and delivery. Each interruption of this cold chain leads to incidents, to the deterioration of the quality of these products to spoilage.

Starting with the production and storage at the producer, the loading / unloading of transport vehicles with refrigerated boxes, cooling or cold boxes at transfer stations (loading / unloading) and during transport to storage and intermediate storage in cold stores and cold storage.

Thus, for example, the cooling in the transport vehicles no longer has an effect if the cold air in the interior of the refrigerator loses the effect of warm air flowing in when opening the hatch. Production and storage facilities are not protected from heat in the area of loading / unloading.

Cold stores are currently being cooled by chillers that attract heat from the adjoining buildings (production, storage) at the opening of the loading / unloading, thus causing dangerous icing of the loading / unloading, in addition to the long cooling times of the cold stores.

These problems are solved with the features listed in the protection claim 1-7.

With this invention, a closed cold chain from production, on the transport, the cold store to the cooling and cooling chambers and the refrigeration furniture is achieved in the trade. The heat sources are eliminated by the arrangement of the horizontal working cold air curtain systems. Also, the newly developed cooling or cold air curtain system technology means a significant reduction in energy costs. Buildings to be cooled no longer require elaborate insulation of the walls, ceilings, doors and gates. This means that considerable savings can be expected in the structural part and the materials used in the building.

An embodiment of the invention will be described with reference to 1 - 7 explained. The mentioned embodiments can be changed according to the given requirements of the building and the cooling situation. Show it

This arrangement of the cold air curtain system ( 17 ) aims at the uniform cooling of the refrigerated box. Also when opening the loading door on the refrigerated box ( 8th ), the cold chain is not interrupted.

To further secure the cold chain, at the loading gate of the delivery, production / storage ( 9 ) a cold air curtain system ( 17 ) are used.

( 4 ) Due to the horizontal cooling capacity of the cold air curtain systems ( 17 ), the cooling capacity can be adjusted as required by switching on the cooling modules ( 11 ) be adjusted. The by cross-flow fans ( 6 ) horizontally generated cooling capacity allows at the entrances a cooling shower ( 21 ), so that no unwanted heat when loading / unloading the goods ( 22 ) into the building to be cooled.

Also, by the horizontal cooling performance of the cold air curtain systems, a temperature zone varying in height ( 11 ) be generated.

( 1 ) Should the cold store, as in this example, be used directly for production or storage ( 2 ), the transitions into the different climatic zones (loading-unloading, production, storage, cooling) through the cold air curtain system ( 17 ) protected.

( 7 ) Furthermore, the positioning of the cold air curtain system ( 17 ) an ice formation ( 19 ) in the transitional area of the different climatic zones ( 20 ) prevented. Thus, an important point of accident prevention by ice formation in the gate area is excluded.

( 1 ) The cold store itself is equipped with a number of cold air curtain systems 17 ) equip. Due to the horizontally generated cooling capacity and the arrangement of the cold air curtain systems ( 17 ) directly on the inside of the building ( 2 ) and the additionally rounded corners of the building ( 17 ), due to the cold air flow ( 6 ) and with the help of the Coanda effect ( 15 ), among other things, the heat of transmission ( 14 ) prevented from entering the building to be cooled.

When opening loading / unloading gates ( 4 ) there is now no unwanted temperature exchange and the associated moisture ( 19 ) can no longer penetrate into the building to be cooled or the cold room or the cold chamber. Thus, the power-consuming cooling is completed by the current cooling methods.
