  Tour de réfrigération à circuit fermé fonctionnant en deux

  
étapes.

  
La présente invention se réfère à un type d'appareil appelé tour de réfrigération à circuit fermé, dans lequel un fluide est refroidi sans contact direct avec  l'air.

  
A cet effet, on fait circuler ce fluide à travers l'intérieur d'un faisceau tubulaire qui est en contact avec l'eau refroidie par de l'air mû par un ventilateur.

  
La Fig. 1 illustre l'appareil présentant les caractéristiques faisant l'objet de l'invention. 

  
Sur cette figure, 1 est le ventilateur; 2 est le garnissage et 3 l'ajutage pulvérisateur d'eau, tout ces éléments faisant partie d'une tour de réfrigération classique.

  
En premier lieu l'eau refroidie est recueillie dans la piscine 4 de la tour dans laquelle est placé le faisceau tubulaire 5 à travers lequel circule le fluide à réfrigérer, proveliant de et retournant à l'extérieur, et en second lieu l'eau réfrigérée à l'intervention d'une pompe 6 est refoulée par le circuit 7 vers le système de pulvérisation 3.

  
La Fig. 2 est une vue schématique du faisceau tubulaire.

  
 <EMI ID=1.1> 

  
du fluide à réfrigérer, 9 est la chambre de distribution d'eau du faisceau tubulaire 10 et 11 est la chambre de distri-bution postérieure pour le retour du fluide.

  
De même, 12 est la prise latérale de l'eau de

  
la piscine pour le circuit extérieur du faisceau, 13 sont les communications entre les divers secteurs du dit faisceau et 14 est la sortie à raccorder à la pompe de recirculation 6. 

  
La caractéristique essentielle de cet appareil réside dans le fait que le processus de refroidissement s'effectue en deux étapes, à savoir : l'eau du circuit secondaire se refroidit dans le garnissage comme dans une tour de réfrigération classique.

  
Le fluide du circuit primaire se refroidit dans' un faisceau tubulaire submergé dans la piscine de la tour

  
en cédant de la chaleur à l'eau.

  
De cette manière, la somme des surfaces

  
d'échange des deux étapes est largement supérieure à

  
celle obtenue avec les systèmes classiques dans lesquels l'eau mouille les tubes du faisceau en étant dans l'ensem-ble directement réfrigérée par l'air. Cependant, la majeure partie de la surface d'échange correspond au garnissage de la tour- de réfrigération, cette surface d'échange étant d'un coût bien infé-
- rieur à celui de la surface d'échange des tubes du faisceau.

  
Le coût peu élevé de cette surface d'échange permet d'utiliser une très grande étendue de cette surface dans le garnissage agencé d'une manière compacte, ce qui permet d'obtenir des appareils avantageux de par leurs dimensions et de par la puissance consommée par leurs moyens mécaniques.

  
Ni l'agencement de la tour classique de l'appareil, ni

  Closed circuit refrigeration tower operating in two

  
steps.

  
The present invention relates to a type of apparatus called a closed circuit refrigeration tower, in which a fluid is cooled without direct contact with air.

  
To this end, this fluid is circulated through the interior of a tube bundle which is in contact with the water cooled by air moved by a fan.

  
Fig. 1 illustrates the apparatus exhibiting the characteristics forming the subject of the invention.

  
In this figure, 1 is the fan; 2 is the packing and 3 the water spray nozzle, all of these elements being part of a conventional refrigeration tower.

  
In the first place the cooled water is collected in the pool 4 of the tower in which the tube bundle 5 is placed through which the fluid to be refrigerated circulates, coming from and returning to the outside, and secondly the refrigerated water at the intervention of a pump 6 is delivered through the circuit 7 to the spraying system 3.

  
Fig. 2 is a schematic view of the tube bundle.

  
 <EMI ID = 1.1>

  
of the fluid to be refrigerated, 9 is the water distribution chamber of the tubular bundle 10 and 11 is the posterior distribution chamber for the return of the fluid.

  
Likewise, 12 is the lateral water intake of

  
the pool for the external circuit of the bundle, 13 are the communications between the various sectors of said bundle and 14 is the outlet to be connected to the recirculation pump 6.

  
The essential characteristic of this device lies in the fact that the cooling process is carried out in two stages, namely: the water of the secondary circuit is cooled in the packing as in a conventional refrigeration tower.

  
The primary circuit fluid cools in a tube bundle submerged in the tower pool

  
by releasing heat to the water.

  
In this way, the sum of the areas

  
exchange of the two stages is much greater than

  
that obtained with the conventional systems in which the water wets the tubes of the bundle while being in the assembly directly refrigerated by air. However, the major part of the exchange surface corresponds to the lining of the cooling tower, this exchange surface being of a much lower cost.
- laughing to that of the exchange surface of the tubes of the bundle.

  
The low cost of this exchange surface makes it possible to use a very large extent of this surface in the packing arranged in a compact manner, which makes it possible to obtain devices which are advantageous by virtue of their dimensions and by the power consumed. by their mechanical means.

  
Neither the classical tower arrangement of the device, nor

  
 <EMI ID = 2.1>

  
tube bundle do not constitute essential characteristics of the apparatus according to the invention.
