The absorption refrigeration machine comprises a heat-transmission tube (11) placed in a concentrating solar collector (12) whose end (6) is situated in the boiler (14). This refrigeration machine is therefore especially suitable for hot countries. <IMAGE>
Description
**ATTENTION** debut du champ DESC peut contenir fin de CLMS **.
REVENDICATIONS
1. Machine frigorifique à absorption, caractérisée en ce qu'elle comprend un tube de transfert de chaleur associé à un capteur solaire.
2. Machine frigorifique selon la revendication 1, caractérisée en ce que le tube de transfert de chaleur constitue une enceinte fermée hermétiquement, dont la paroi intérieure est tapissée d'un treillis métallique à structure capillaire.
L'invention a trait à une machine frigorifique à absorption.
Dans les installations et appareils frigorifiques connus utilisant le principe de l'absorption découvert par Carré en
France en 1859, on utilise un chauffage pour le bouilleur, ceci afin de vaporiser le fluide frigorigène, le chauffage étant réalisé à l'aide d'une résistance électrique ou d'une flamme de gaz ou de pétrole.
L'inconvénient de ce type de chauffage est donc de nécessiter un apport d'énergie électrique ou de carburant pour produire la quantité de chaleur nécessaire. L'invention remédie à cet inconvénient en proposant une machine frigorifique qui est caractérisée en ce qu'elle comprend un tube de transfert de chaleur ou caloduc associé à un capteur solaire.
On comprendra mieux l'invention à la lecutre de la description suivante faite à titre d'exemple et se rapportant aux dessins ci-joints:
-fig. 1: vue en coupe d'un tube de transfert de chaleur.
- fig. 2: vue de la machine frigorifique à absorption partiellement coupée, équipée d'un tube de transfert de chaleur.
Un tube de transfert de chaleur comme représenté à la fig.
1, est constitué d'un tube métallique appelé parfois réservoir formant une enceinte fermée hermétiquement dont les parois intérieures sont tapissées d'un fin treillis métallique (2) de fa çon à constituer une structure capillaire, et qui contient un fluide caloporteur, dont la nature et la quantité sont choisies de manière à ce que, dans les conditions souhaitées, il puisse se trouver à l'état d'équilibre liquide-vapeur, la phase liquide saturant la structure capillaire.
Si l'on chauffe une extrémité (3) du tube (1), le fluide caloporteur s'évapore à la température donnée dans la partie chauffée et la vapeur va se condenser à la même température dans la partie refroidie (4), libérant alors la plus grande partie de l'énergie thermique absorbée à l'extrémité chauffée. Le liquide revient ensuite par capillarité dans la structure capillaire (2) jusqu'à l'extrémité chauffée (3) où il s'évapore de nouveau et il s'établit ainsi un cycle de transfert de chaleur permanent.
Si nous plaçons une extrémité (11), fig. 2, d'un tel tube dans un dispositif concentrant les rayons du soleil, par exemple un réflecteur parabolique (12), I'autre extrémité (6) étant placée dans le bouilleur (14) d'une machine frigorifique à absorption comprenant par ailleurs les éléments communs aux machines de ce type, à savoir le condenseur (7), Absorbeur (5), I'évaporateur (8), I'échangeur (9) et le rectificateur (10), nous assurons en suffisance l'apport de chaleur nécessaire au fonctionnement de cette machine sans utiliser aucune autre énergie que l'énergie solaire. Le froid produit au niveau de l'évaporateur (8) permettra donc de réfrigérer l'enceinte (13) par ailleurs isolée thermiquement.
L'invention permet donc de réaliser des installations frigorifiques de toutes tailles, pouvant fonctionner à l'énergie solaire ou à l'aide de chaleur récupérée, ainsi amenée au bouilleur par le tube de transfert de chaleur, convenant particulièrement aux pays chauds qui sont fortement ensoleillés et où la conservation des aliments et le séjour des personnes sont malaisés sans les installations frigorifiques actuelles qui consomment beaucoup d'énergie, soit électrique, soit sous forme de pétrole ou de gaz.

CLAIMS
1. Refrigeration absorption machine, characterized in that it comprises a heat transfer tube associated with a solar collector.
2. Refrigerating machine according to claim 1, characterized in that the heat transfer tube constitutes a hermetically sealed enclosure, the inner wall of which is lined with a wire mesh with capillary structure.
The invention relates to an absorption refrigeration machine.
In known refrigeration systems and devices using the absorption principle discovered by Carré in
France in 1859, a heater is used for the boiler, this in order to vaporize the refrigerant, the heating being carried out using an electrical resistance or a gas or petroleum flame.
The disadvantage of this type of heating is therefore to require a supply of electrical energy or fuel to produce the amount of heat required. The invention overcomes this drawback by proposing a refrigeration machine which is characterized in that it comprises a heat transfer tube or heat pipe associated with a solar collector.
The invention will be better understood from the following description given by way of example and relating to the attached drawings:
-fig. 1: sectional view of a heat transfer tube.
- fig. 2: view of the partially cut absorption refrigeration machine, fitted with a heat transfer tube.
A heat transfer tube as shown in fig.
1, consists of a metal tube sometimes called a reservoir forming a hermetically sealed enclosure whose internal walls are lined with a fine metal mesh (2) so as to constitute a capillary structure, and which contains a heat transfer fluid, the nature and quantity are chosen so that, under the desired conditions, it can be in the liquid-vapor equilibrium state, the liquid phase saturating the capillary structure.
If one end (3) of the tube (1) is heated, the heat transfer fluid evaporates at the temperature given in the heated part and the vapor will condense at the same temperature in the cooled part (4), thus releasing most of the thermal energy absorbed at the heated end. The liquid then returns by capillarity in the capillary structure (2) to the heated end (3) where it evaporates again and there is established a permanent heat transfer cycle.
If we place one end (11), fig. 2, of such a tube in a device concentrating the rays of the sun, for example a parabolic reflector (12), the other end (6) being placed in the boiler (14) of an absorption refrigeration machine further comprising the elements common to machines of this type, namely the condenser (7), Absorber (5), the evaporator (8), the exchanger (9) and the rectifier (10), we ensure sufficient supply of heat necessary to operate this machine without using any energy other than solar energy. The cold produced at the evaporator (8) will therefore allow the enclosure (13), which is also thermally insulated, to be refrigerated.
The invention therefore makes it possible to produce refrigeration installations of all sizes, which can operate on solar energy or using recovered heat, thus brought to the boiler by the heat transfer tube, particularly suitable for hot countries which are strongly sunny and where the preservation of food and the stay of people are difficult without the current refrigeration installations which consume a lot of energy, either electric, or in the form of oil or gas.
