Description

Die Neuerung betrifft eine Vorrichtung an einer Luftkühleinrichtung für dia Kühlung von Kornerfrachten, etwa Getreide, oder auch von Futterpreßlingen (Pellets)«The innovation relates to a device on an air cooling device for cooling grain loads such as grain, or from pellets «

Zur Durchführung der Kühlung stehen heute transportalle Luftlcühlvorrichtungen zur Verfügung, die mittels Schlauchleitungen an die jeweils zu kühlenden Silozellen, Schütthallen oder auch Durchlauf-Kuhler angeschlossen werden· Diese Vorrichtungen erzeugen einen Kaltluftstrom, der durch das aufgeschüttete oder herabrieselnde Getreide oder sonstige Gut streicht und diesem die abzuführende Wärme entzieht· Im allgemeinen ist mit diesem Wärmeaustausch auch ein Stoffaustausch verbunden, d.h. je nach des Wassergehalt des Kühlgutes erfährt dieses eine Trocknung oder Befeuchtung durch den Kaltluftstres* Luftfeuchtigkeit und Feuchtegrad der Kühlgüter sind durch dasTransport all are available today to carry out the cooling Air cooling devices are available by means of hose lines connected to the silo cells, bulk halls or continuous cooler to be cooled · These devices create a flow of cold air that flows through the heaped or brushing down grain or other goods and removing the heat to be dissipated from them · In general This heat exchange is also associated with a mass transfer, i.e. depending on the water content of the refrigerated goods this one drying or humidification through the cold air stream * The humidity and degree of humidity of the refrigerated goods are affected by the

gegenseitige Sorptloneglelchgewlcht miteinander verknüpft· Während die relative Feuchtigkeit der die Luftkühlvorrichtung verlassenden Kaltluft einen wenig veränderlichen Wert nahe der Sättigung aufweist, kann der Wasserciehalt der hier interessierenden Güter in weiten Grenzen schwanken· Das Sorptionsgleichgewicht BiIt nahezu gesättigter Luft liegt für die «eisten dieser Güter bei etwa 2Θ % Wassergehalt. Im Erntezustand liegen die Wassergehalte etwa in dieser Größenordnung, während für längere Lagerung ein Wassergehalt von 14 % angesetzt wird, der mit einer Luftfeuchtigkeit von etwa 60 % im Gleichgewicht steht. Für so trockenes Gut ist daher sins Kühlung mit gesättigter Luft nicht vorteilhaft. Andererseits ist diese bei vielen anderen Anwendungszwecken durchaus sinnvoll, insbesondere bei der Pufferlagerung erntefeuchten Getreides vor der Trocknung·Mutual Sorptloneglelchgewlcht linked with each other · While the relative humidity of the cold air leaving the air cooling device has a little changeable value close to saturation, the water content of the goods of interest here can fluctuate within wide limits · The sorption equilibrium BiIt of almost saturated air is for most of these goods around 2Θ % water content. When harvested, the water content is roughly in this order of magnitude, while a water content of 14 % is assumed for longer storage, which is in equilibrium with an air humidity of about 60 %. Cooling with saturated air is therefore not advantageous for such dry goods. On the other hand, this is quite useful for many other purposes, especially when buffer storage of harvest-moist grain before drying.

Der Heuerung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die eine Anpassung der Kühlluftfeuchtigkeit an den jeweiligen Bedarfsfall ermöglicht·The hiring is based on the task of a device to create an adjustment of the cooling air humidity to the respective need made possible

Vorteilhaft ist der zur Nachwärmung dienende Wärmeaustauscher im Nebenschluß zum Verflüssiger an den Kältekreislauf angeschlossen«.Cold air leaving the air cooler comes in after warming up Serving heat exchanger is arranged. The bypass heat exchanger used for reheating is advantageous connected to the refrigerant circuit to the condenser «.

Bei einer neuerungsgemäßen Vorrichtung ist es vorteilhaft, daß in einer Zuleitung zum Nachwärmer ein Hegelventil zur Dosierung der Nachwärmung eingebaut ist, um die relative Feuchtigkeit der kalten Luft dem jeweiligen Bedarfsfall anzupassen.In a device according to the invention, it is advantageous that a Hegel valve in a feed line to the reheater to dose the reheating is built in, to adjust the relative humidity of the cold air as required adapt.

For this purpose, a partial flow is passed hot refrigerant vapor after exiting the refrigerant compressor via the reheater · The amount of this partial flow can be regulated manually or automatically can be dosed by a humidity sensor in the air flow in such a way that the desired air humidity is achieved
