Description
Verfahren zur Erzeugung von Kälte Die Erfindung betrifft ein Verfahren zur Kälteerzeugung, bei dem eine Lösung von Ammoniak in Wasser als Kältemittel benutzt wird. Es kommen Lösungen solcher Konzentration zur Anwendung, die unter normalen Temperatur- und Druckverhältnissen ohne besondere Vorsichtsmaßregeln behandelt werden können, wie z. B. der 25o/oige Salmiakgeist des Handels.Method for generating cold The invention relates to a method for refrigeration, in which a solution of ammonia in water is used as a refrigerant will. Solutions of such a concentration are used that are below normal Temperature and pressure conditions are treated without special precautionary measures can, such as B. the 25% salmiak spirit of the trade.
Nach dem Verfahren wird das Kältemittel dadurch zur Verdampfung gebracht, daß es in einem geschlossenen Behälter unter verminderten Druck gesetzt wird, wobei die zur Verdampfung erforderliche Wärmemenge der Umgebung entzogen wird und diese abkühlt. Die Evakuierung des Gefäßes erfolgt mit Hilfe einer Wasserstrahlpumpe, deren Treibwasser das ammoniakhaltige verdampfte Kältemittel wieder löst und fortführt. Bei diesem Verfahren geht das Kältemittel mit dem wegfließenden Treibwasser verloren. Es lassen sich bei Verdampfung einer 25°/oigen Salmiakgeistlösung unter Benutzung einer einfachen Wasserstrahlpumpe, die mit Leitungswasser von üblicher Temperatur betrieben wird, in kürzester Zeit Temperaturen von -20° C erzielen.After the process, the refrigerant is made to evaporate, that it is placed under reduced pressure in a closed container, whereby the amount of heat required for evaporation is withdrawn from the environment and this cools down. The vessel is evacuated with the help of a water jet pump, whose motive water dissolves the ammonia-containing evaporated refrigerant again and carries it away. In this process, the refrigerant is lost with the driving water flowing away. It can be used with evaporation of a 25% strength ammonia solution a simple water jet pump that works with tap water at normal temperature is operated, can reach temperatures of -20 ° C in a very short time.
Da Salmiakgeist überall billig im Handel zu haben ist, so läßt sich mit Hilfe der auch überall vorhandenen Wasserleitung unter Benutzung der sehr einfachen und billigen Apparatur eine für jeden Haushalt erschwingliche Kühlvorrichtung betreiben.Since ammonia is cheap everywhere in the trade, so can with the help of the water pipe that is also everywhere using the very simple and cheap equipment to operate a cooling device that is affordable for every household.
Die beiliegende Zeichnung veranschaulicht eine Vorrichtung zur Ausführung desVerfahrens. Das Kältemittel wird in einen zylindrischen vakuumdichten Behälter :i eingefüllt, der innen zweckmäßig mit Dochtgewebe 2 ausgekleidet ist, wodurch unabhängig vom Niveau des Kältemittels eine Verdampfung auf der ganzen Gefäßwand stattfindet. Oben trägt der Behälter einen Rohrkrümnier, der mittels des Vakuumschlauches 3 mit der Wasserstrahlpumpe q. in Verbindung steht, die an einen normalen Wasserleitungshahn 5 angeschlossen ist.The accompanying drawing illustrates an apparatus for implementation of the procedure. The refrigerant is placed in a cylindrical vacuum-tight container : i filled, the inside is suitably lined with wick fabric 2, whereby evaporation on the entire vessel wall regardless of the level of the refrigerant takes place. At the top, the container has a pipe elbow that is connected to it by means of the vacuum hose 3 with the water jet pump q. that communicates with a normal water tap 5 is connected.
Das Verdampfergefäß z kann je nach dem gewünschten Verwendungszweck in der verschiedensten Form und Größe ausgebildet werden. In der dargestellten Kerzenform kann es zur Kühlung des Inhaltes enghalsiger, doppelwandiger Vakuumflaschen 6, sozusagen als Tauchkühler, mit Erfolg verwendet werden.The evaporation vessel z can depending on the desired use can be designed in a wide variety of shapes and sizes. In the illustrated candle shape it can be used to cool the contents of narrow-necked, double-walled vacuum bottles 6, so to speak as an immersion cooler, can be used with success.
Entsprechend größer, evtl. mit Kühlrippen versehen, eignet sich ein derartiger Verdampfer auch für größere Kühlschränke und Kühlräume. Durch Einbau von Gefäßen zur Aufnahme von Wasser oder anderen zu gefrierenden Flüssigkeiten kann er zur Kristall- oder Speiseerzeugung ausgestaltet werden. Es lassen sich auch für intermittierenden Betrieb bei Kühlschränken mantelförmige Kältespeicher für Eis oder Sole anordnen.Correspondingly larger, possibly provided with cooling fins, is suitable Such an evaporator also for larger refrigerators and cold rooms. Through installation of vessels for holding water or other liquids to be frozen it can be designed for crystal or food production. It can also be used for intermittent operation in refrigerators jacket-shaped cold storage for ice or arrange brine.
Die Zuführung des Kältemittels zum Verdampfer geschieht bei kleineren Apparaturen durch bedarfsweise Füllung, bei größeren Anlagen kann das Kältemittel kontinuierlich aus Vorratsbehältern nachgefördert werden. Die im Verdampfer zurückbleibende verarmte Lösung ist von Zeit zu Zeit abzulassen.The refrigerant is fed to the evaporator for smaller ones Apparatus by filling as required, in larger systems the refrigerant can be continuously replenished from storage containers. The one left in the evaporator impoverished solution is drained from time to time.
Statt die Wasserstrahlpumpe mit Leitungswasser zu betreiben, kann der nötige Betriebsdruck in einem geschlossenen Wasserkreislauf auch durch eine Druckpumpe erzeugt werden. wobei das Wasser, wenn es sich zu weit mit Ammoniak angereichert hat, erneuert werden muß. Das mitAmmoniak angereicherte Lösungswasser kann in dem Verdampfer erneut zur Kälteerzeugung benutzt werden.Instead of operating the water jet pump with tap water, you can the necessary operating pressure in a closed water circuit also through a Pressure pump are generated. taking the water when it becomes too enriched with ammonia has to be renewed. The solution water enriched with ammonia can be in the The evaporator can be used again to generate cold.
