(a) enfriamiento de ios alabes condensadores rotatorios (4).(a) cooling of the rotary condenser blades (4).

Como se ilustra en las figuras, se prevé que los alabes rotatorios se encuentren parcialmente inmersos en agua fría contenida en un contenedor (8). De preferencia, los alabes se encuentra sumergidos entre un tercio y la mitad de su diámetro.As illustrated in the figures, it is envisaged that the rotating vanes are partially immersed in cold water contained in a container (8). Preferably, the blades are submerged between a third and half of its diameter.

En contacto con el deposito de agua fría, la temperatura de los alabes condensadores rotatorios (4) desciende a entre cero y diez grados centígrados. Tal enfriamiento es alcanzado en virtud de que la temperatura del agua contenida enel deposito (8) se encuentra a una temperatura entre 0o y 10° C.In contact with the cold water tank, the temperature of the rotating condenser vanes (4) drops to between zero and ten degrees Celsius. Such cooling is achieved by virtue of the temperature of the water contained inthe tank (8) is at a temperature between 0 ° and 10 ° C.

En la segunda etapa, los alabes rotatorios (4) inmersos en el agua fría rotan y la porción que estaba inmersa en el contenedor de agua fría, emerge.In the second stage, the rotating vanes (4) immersed in the cold water rotate and the portion that was immersed in the cold water container emerges.

En virtud de que los alabes se encuentran mojados con agua fría, se proveen medios de barrido mecánico (6 A) de refrigerante para retirar la capa de agua que moja la superficie de los alabes (4) enfriados. Dichos medios de barrido de refrigerante (6 A) consisten en una pluralidad de bandas de barrido de refrigerante que se extienden horizontalmente desde aproximadamente el centro hasta el extremo de los alabes (4). Dichas bandas se encuentran en estrecho contacto con la superficie de cada alabe que emerge del contenedor de agua fría.Because the blades are wet with cold water, mechanical sweeping means (6 A) of refrigerant are provided to remove the layer of water that wets the surface of the cooled blades (4). Said coolant scanning means (6 A) consists of a plurality of coolant sweeping bands that extend horizontally from about the center to the end of the blades (4). These bands are in close contact with the surface of each blade that emerges from the cold water container.

Preferentemente se dispone una banda entre cada disco, de modo que las orillas laterales de cada banda se estrechen contra las caras de los alabes adyacentes. Pero como será evidente a un técnico en la materia es posible disponer una banda de barrido de refrigerante adyacente a cada alabe rotatorio. Además puede disponerse opcionalmente un medio mecánico de tensión, tal como un resorte, de manera que la banda de barrido ejerza cierta presión sobre la superficie del alabe rotatorio.Preferably a band is arranged between each disc, so that the lateral edges of each band are pressed against the faces of the adjacent blades. But as will be apparent to a person skilled in the art it is possible to arrange a sweeping band of coolant adjacent to each rotary vane. In addition, a mechanical tensioning means, such as a spring, can optionally be arranged so that the sweeping band exerts some pressure on the surface of the rotating blade.

Las bandas de barrido de refrigerante tienen por objeto retirar el agua fría que moja la superficie del alabe rotatorio enfriado. Las bandas de barrido en estrecho contacto con la superficie de cada alabe, retiran substancialmente el agua que moja la superficie de los alabes. Además, dichas bandas de barrido de refrigerante tienen por objeto proveer una cubierta de protección para el agua contenida en el contendor. Dicha cubierta tiene por objeto evitar que el agua contenida en el contenedor se evapore al contacto con la corriente de aire.The purpose of sweeping coolant strips is to remove cold water that wets the surface of the cooled rotary vane. The sweeping bands in close contact with the surface of each blade substantially remove the water that wets the surface of the blades. In addition, said coolant sweeping bands are intended to provide a protective cover for the water contained in the container. Said cover is intended to prevent the water contained in the container from evaporating on contact with the air flow.

Para la fabricación de las bandas de barrido se prefiere el empleo de hule o plástico, Dichos materiales poseen la flexibilidad adecuada para operar sin que se fracturen. Las bandas de barrido de hule pueden ser semejantes a los hues de limpiadores de parabrisas de autos.The use of rubber or plastic is preferred for the manufacture of the sweeping bands.

(10) a través del canal (3).(10) through the channel (3).

En virtud del gradiente de temperatura entre la corriente de aire ambiental y la superficie de los alabes rotatorios, el vapor de aire cede su calor latente a los alabes rotatorios y se condensa sobre la superficie de los alabes. De esta manera aparecen gotas de agua sobre cada una de las caras de los alabes del conjunto de alabes rotatorios.By virtue of the temperature gradient between the ambient air stream and the surface of the rotating blades, the air vapor gives its latent heat to the rotating blades and condenses on the surface of the blades. In this way drops of water appear on each of the faces of the blades of the set of rotary blades.

Con el agua condensada sobre su superficie, los alabes rotatorios vuelven a introducirse en el contenedor (8) de agua fría, en donde vuelven a enfriarse.With the condensed water on its surface, the rotating blades are reintroduced into the cold water container (8), where they are cooled again.

B) consisten de una sola banda, la porción de barrido de condensado de dicha banda tiene una cierta inclinación que tiene por objeto permitir que el agua condensada escurra hacia el centro de la banda hacia un orificio provisto en dicha banda por medio del cuál el agua condensada cae al interior del contendor (15).B) consist of a single band, the condensate sweep portion of said band has a certain inclination which is intended to allow the condensed water to drain towards the center of the band towards a hole provided in said band by means of which the water condensed falls into the container (15).

Aún cuando no se emplee bandas de barrido de condensado (6 B), se prefiere disponer una banda en el espacio definido entre los alabes (4). Dicha banda tiene por objeto impedir que el a're ambiental se ponga en contacto con la superficie de agua del contenedor (8) y la evapore.Even if no condensate sweeping bands (6 B) are used, it is preferred to arrange a band in the defined space between the blades (4).
