Description

       

   <EMI ID=1.1> 

  
Augmentation du rendement d'un circuit de chauffage à

  
partir d'un fluide chauffé par l'énergie solaire.

  
Description et 1ère revendication:

  
Le procédé, faisant l'objet du brevet, consiste à augmenter

  
la quantité d'énergie captée par le panneau solaire et transportée par le fluide caloporteur, en agissant sur le rendement de l'installation.

  
A cette fin, on utilise deux ou plusieurs boilers dont les circuits chauffants sont raccordés en série. Les circuits

  
d'eau à chauffer sont également placés en série de telle sorte

  
que le dernier boiler, celui de puisage, reçoive le fluide caloporteur chaud, venant des capteurs.

  
Le premier boiler, celui d'arrivée, reçoit le fluide caloporteur après sont passage dans les autres boilers, et le recycle vers la batterie de capteurs.

  
Le circuit d'eau à chauffer de ce premier boiler est raccordé

  
au réseau d'alimentation et la sortie de ce circuit passe dans

  
le circuit correspondant du second boiler, et ainsi de suite, jusqu'au dernier boiler de puisage.

INTERET DU SYSTEME.

  
Ce procédé consiste à favoriser un facteur essentiel du rendement d'une installation thermique: la différence de température existant entre les deux milieux appelés à réaliser les échanges thermiques.

  
Les boilers en cascade vont progressivement réduire la température du fluide caloporteur, au profit d'un échauffement progressif des réserves d'eau dans les différentes unités; eau

  
qui est supposée arriver froide du réseau d'entrée. 

  
On constitue donc avant le boiler de puisage, une ou plusieurs réserves d'eau tempérée.

  
Le rendement de ces échangeurs (boilers) est fonction du ^. température: au moment où la température du dernier boiler approchera celle du fluide caloporteur, son efficacité diminuera jusqu'au zéro et le boiler suivant prend la relève

  
en augmentant sa température; et ainsi de suite.

  
La réserve d'eau chaude et tiède se trouve donc augmentée,

  
ainsi que la chaleur en réserve. Ce rapport entre la quantité d'eau et celle de chaleur est assez évident, mais la disposition en étages permet ( outre la montée en température

  
au boiler de puisage ) d'obtenir avant recyclage, un fluide caloporteur froid (thermiquement épuisé), qui augmentera donc

  
 <EMI ID=2.1>

Increase in the efficiency of a heating circuit

  
from a fluid heated by solar energy.

  
Description and 1st claim:

  
The process, which is the subject of the patent, consists in increasing

  
the quantity of energy captured by the solar panel and transported by the heat transfer fluid, acting on the efficiency of the installation.

  
To this end, two or more boilers are used, the heating circuits of which are connected in series. The circuits

  
of water to be heated are also placed in series in such a way

  
that the last boiler, the draw-off boiler, receives the hot heat transfer fluid from the sensors.

  
The first boiler, the inlet one, receives the heat transfer fluid after passing through the other boilers, and recycles it to the battery of sensors.

  
The water circuit to be heated for this first boiler is connected

  
to the supply network and the output of this circuit passes through

  
the corresponding circuit of the second boiler, and so on, up to the last draw-off boiler.

INTEREST OF THE SYSTEM.

  
This process consists in favoring an essential factor of the efficiency of a thermal installation: the temperature difference existing between the two environments called upon to carry out the thermal exchanges.

  
The cascade boilers will gradually reduce the temperature of the heat transfer fluid, in favor of a gradual heating of the water reserves in the different units; water

  
which is supposed to arrive cold from the input network.

  
One or more reserves of tempered water are therefore constituted before the draw-off boiler.

  
The efficiency of these exchangers (boilers) depends on the ^. temperature: when the temperature of the last boiler approaches that of the heat transfer fluid, its efficiency will drop to zero and the next boiler takes over

  
by increasing its temperature; And so on.

  
The hot and lukewarm water reserve is therefore increased,

  
as well as the heat in reserve. This relationship between the quantity of water and that of heat is fairly obvious, but the arrangement in stages allows (in addition to the rise in temperature

  
before recycling, to obtain a cold heat transfer fluid (thermally exhausted), which will therefore increase

  
 <EMI ID = 2.1>

  
this.

Le fluide caloporteur d'une installation de chauffage solaire réchauffant successivement deux ou plusieurs boilers en série, The heat transfer fluid of a solar heating installation successively heating two or more boilers in series, sera recyclé le plus froid possible, de manière à ce qu'il will be recycled as cold as possible, so that it libère totalement ses calories en préchauffant le ou les boilers d'attente, ainsi le rendement du capteur solaire s'en trouve totally releases its calories by preheating the standby boiler (s), thus the efficiency of the solar collector is there augmenté. La réduction du débit caloporteur favorisera l'élévation de température du boiler de puisage, au détriment du facteur global d'efficacité, et inversement. increases. Reducing the heat transfer flow rate will increase the temperature of the draw-off boiler, to the detriment of the overall efficiency factor, and vice versa.
