Kältemaschinen werden offenbar die größten Dienste leisten, wenn sie ebenso_: einfach und. wirtschaftlich gestaltet sind wie Heizvorrichtungen. Diesen Bedingungen genügen die bisher bekannten Vorrichtungen nicht,' bei denen z. B. die Abkühlung des Wassers durch Vorbeiströmen an durch Eis gekühlten Körpern geschieht. Vielmehr soll nach der neuen Erfindung die bekannte Abkühlung bezw. das Gefrieren von Wasser durch Verdampfung im Vakuum benutzt werden, wie dies z. B., bei der bekannten Carre'schen Maschine der Fall ist. Bisher aber^xwurde bei allen diesen Vorrichtungen Schwefelsäure zur Absorption des Wassers benutzt, dagegen soll bei der neuen Vorrichtung die Absorption des Dampfes durch einen wassergekühlten Kondensator geschehen. . ' Es sei angenommen, d^ß Dampf einem sso Dampfkessel von ioo°, also unter Atmosphärendruck, entnommen werde, nämlich wie bei Heizanlagen. Der Ejektor kann aber hur dann wirken, wenn er in einen Kondensator ragt, in welchem ein Druck unterhalb der aj Atmosphäre herrschtChillers will obviously do the greatest service if they are just as _: simple and. are designed as economical as heating devices. These conditions do not meet the previously known devices, 'where z. B. the cooling of the water is done by flowing past bodies cooled by ice. Rather, according to the new invention, the known cooling BEZW. the freezing of water by evaporation in a vacuum can be used, as z. B., is the case with the well-known Carre's machine. So far, but ^x in all these devices was used sulfuric acid for absorption of the water, on the other hand to be achieved by a water-cooled condenser with the new device, the absorption of the vapor. . 'It is assumed, d ^ ß steam sso a steam boiler of ioo °, ie below atmospheric pressure, will withdrawn, namely, as in heating systems. The ejector can only work when it protrudes into a condenser in which the pressure is below the aj atmosphere

Die Erfindung wird aus den Figuren verständlich! The invention can be understood from the figures!

Die Vorrichtung ist in Fig, 1 veranschaulicht. Die Öffnung 1 ist in Verbindung mit einem 3<s Wasser von ioo° enthaltenden Kessel. Von dieser Öffnung aus ragt eine Düse 2 in eine Kammer 3, die durch Stutzen 4 mit dem Gefäß in Verbindung steht, in welchem man das Wasser unter Luftleere zum Sieden bringen will. Der Düse 2 gegenüber ragt in die Kammer 3 der Kegel 5 des Ejektors; mit dem anderen Ende mündet der Kegel in die Kondensationskammer 6. Das Kondensationswasser tritt unter Druck in diese Kammer durch Rohr 7, das mit seiner Mündung gegen einen zweiten Kegel 8 gerichtet ist, der am anderen Ende in eine Kammer 9 mündet; in letzterer herrscht ein Druck, der ein wenig höher als der Atmosphärendruck ist.The device is illustrated in FIG. The opening 1 is in communication with a 3 <s water from a boiler containing 100 °. from This opening protrudes from a nozzle 2 into a chamber 3, which is connected to the vessel by connecting piece 4 in which the water is boiled in a vacuum wants to bring. Opposite the nozzle 2, the cone 5 of the ejector protrudes into the chamber 3; the other end of the cone opens into the condensation chamber 6. The condensation water enters this chamber under pressure through tube 7 connected to its mouth is directed against a second cone 8, which at the other end into a chamber 9 flows out; in the latter there is a pressure which is a little higher than atmospheric pressure.

Das in den Kegel 9 einströmende Wasser sucht, indem es den in der Kammer 6 vorhandenen Dampf kondensiert und. die. mit ihm gemischte Luft mitreißt, in dieser Kammer Luftleere zu erzeugen. Der Druck, welcher sich in der Kammer 6 herzustellen sucht, ist gleich der der Temperatur des Kondensationswassers entsprechenden Dampfspannung. Diese Temperatur ist wenig verschieden von der atmosphärischen Temperatur und beträgt z. B. 35° C. Der Druck in der Kammer 6 5§ ist alsdann gleich 0,055 Atmosphäre,The inflowing water into the cone 9 studied by it condenses present in the chamber 6 and steam. the. entrains air mixed with it, creating a vacuum in this chamber. The pressure which seeks to establish itself in the chamber 6 is equal to the vapor tension corresponding to the temperature of the condensation water. This temperature is little different from the atmospheric temperature and is z. B. 35 ° C. The pressure in chamber 6 5§ is then equal to 0.055 atmosphere,

Der unter Atmosphärendruck durch die Öffnung ι einströmende Dampf strömt, indem er sich mit großer Geschwindigkeit durch die Kammer 3 und den Kegel 5 bewegt, in 6© die Kammer 6. Hierbei reißt, er den in der Kammer 3 vorhandenen Dampf mit und erzeugt daselbst eine Luftleere, welche stärker ist als die in der Kammer 6 unterhaltene.The steam flowing in through the opening under atmospheric pressure flows through it at high speed the chamber 3 and the cone 5 moves, in 6 © the chamber 6. This tears, he the in the Chamber 3 with existing steam and creates an air void there, which is stronger is than that maintained in Chamber 6.

Diese Temperaturerniedrigung wird um so größer sein, je geringer, das durch den This temperature decrease will be the greater, the lower that is caused by the

Claims

Nozzle 4 entering steam weight is what every kilogram of the steam flowing through the nozzle 2 has to be carried away.

This device, which forms the essential link of the present refrigeration machine, isi as simple as possible and can be a pipe be incorporated.

A boiler ro (Fig. 2) generates water vapor from atmospheric pressure. This steam initially flows through an engine 11 without Control of any system, at the most appropriate

. ' most moderate a rotating engine, and then enters the ejector 1,2 ... 8,9. The chamber 9 of the latter is in communication with the boiler through the intermediary of a with Swimmer equipped pot 12. «The The float keeps the water level in the kettle at the same level by gradually increasing it equal to the formed weight of steam

so lets in weight of water.

As the steam flows through the ejector, it creates a vacuum in the vessel 13. The latter contains water, which is held in it by means of a float 14 at the same level.

One driven by the engine 11 Pump 15 sucks the cooled in vessel 13 Water out and hurls it, in distribution to the rooms to be cooled of the House, in the form of rays in the air.

The water falls back in basins 17, 17 ... from which it leads a return line to the box 18, from where it recedes into the vessel 13.

Since the steam weight generated in the vessel 13 is necessarily greater than the weight condensed by the water jets Steam, box 18 would eventually become empty will. We now obtain a certain water level in the latter by mediating Feed the float tap water from a storage tank 19 provided in the upper part of the house. The latter must be withdrawn from the action of the sun. He also yeasts the condensation water, which is to be fed under pressure into the chamber 6 of the ejector. After this Water is warmed up by the condensation of the steam, it becomes by the Shower 20 poured into the atmosphere, so by contact with the outside air its initial temperature returned and collected from the basin, 21. One too driven by the engine 11 pump 22 conveys the water from the basin in the container 19 back.

To put the system into operation, after boiler 10 and container 19 has filled the fire. As soon as the steam flows out freely through valve 23, one needs only to open the cock 24.

The water of the container 19 flows into the chamber 6 of the ejector and creates a vacuum there; this causes the steam to flow into the ejector; the device is now in operation. To turn off the latter, one only needs to close the tap 24 and extinguish the fire.

As can be seen, the same water is always present in the device described reused what is essential to keep the kettle 10 and the vessel 13 free of scale to keep.

Sponsorship τ claim:

Cooling resp. Freezer in which the water is partially evaporated is cooled in vacuo, characterized in that the vacuum generated by a steam ejector, but the exhaust steam of the ejector by a downstream water jet condenser is precipitated.
