F. PALLAUSCH m VIENNA. Air cooler.

Patented in the German Empire on September 3, 1878.

According to the inventor, this cooling device differs from all other devices of this genus in that a stream of air is driven over humidified rough evaporation surfaces, which with it Are surrounded by ice in such a way that the current of air does not come into contact with this ice comes. The advantage which is achieved thereby consists in that the The heat used up by evaporation is partly withdrawn from the ice, so that it does so not only melts much more slowly and thereby the need for ice is much lower, and at lively evaporation even creates new ice respectively. the existing on one lower temperature level can be brought.

The liquid brought to evaporation can be water, ether, alcohol or something else any easily flowing substance or a mixture of such substances.

The accompanying drawing shows in Fig. 1 a top view, in Fig. 2 a view of a such a cooling device, used when cooling beer in the fermentation vats.

In this case, B is a horseshoe-shaped box, which is surrounded on all sides with ice Z> -: -. And E. The same is inside with oblique, mutually facing strips or plates α α made of wood, tinned iron, zinc or other suitable material, which are covered with felt or cotton fabrics, with coarse fabrics or other porous material to prevent the evaporating liquid to give the largest possible surface.

G is a perforated channel that runs around the inside of the box B on its upper edge and is filled with pieces of ice; or water is introduced into it.

A is the supply pipe through which a forceful flow of air created in some way is fed into the box. According to the peculiar arrangement of the strips or plates α α, it must stroke in a zigzag path over the damp evaporation surfaces. A part of the air flow is used to melt the pieces of ice lying in the channel G. The water A gradually accumulating in box B is drained through a tap located close to the bottom of the box

The water which collects in the box F which surrounds the vessel B with the ice can be drained off through another tap. The cooled air is after it has passed the box B , through the pipe C into the room to be cooled, here .z. B. thus by means of the two pipes //, passed around the cooling vessels K , which float in the fermentation vats M on the beer. J are taps for regulating the incoming air. L are the outflow pipes for the stale air.

By means of this apparatus it is possible to have air of ordinary room temperature in some To cool for a few seconds to a few degrees above zero.

Finally, it should be emphasized again here that it was constructed analogously, even if in form or refrigerators modified in insignificant details this system also for the distillery, in the sugar production and in all Apply to those branches of manufacture where a cooling of the temperature is necessary is. They can also be used for ventilation or cooling in theaters, buildings, Ships, railroad cars, for keeping food cool during transport and similar purposes are used.

Claims (1)

Patent claim: A cooling apparatus in which the lowering of the temperature is achieved by the fact that one conducts a stream of air over rough, moist, porous materials with a large surface, which are surrounded by ice in such a way that the current of air does not get in with this ice at all Touch comes; an apparatus in which the cooling is not done by evaporation alone and not through the ice alone, but through mutual interaction of these two factors is achieved,
