Description

Cœur de pompe à chaleur compact de type eau/eau, et pompe à chaleur comportant un tel cœur de pompe Heart of a compact water / water type heat pump, and heat pump comprising such a pump core
L'invention concerne les pompes à chaleur de type eau/eau. Ces équipements permettent de capter l'énergie thermique disponible dans l'air, dans les couches supérieures de la terre ou encore dans de l'eau libre, de concentrer cette énergie et de la restituer sous cette forme concentrée (à température plus élevée) pour alimenter un circuit de chauf¬ fage à eau chaude. Par « eau/eau » on entendra un type de pompe à chaleur dans lequel le circuit de captage de chaleur et le circuit de restitution de chaleur (chauf¬ fage) sont tous deux des circuits où circule un liquide, par opposition aux systèmes « eau/air » ou « air/air », étant bien entendu qu'en fonction des besoins l'eau peut être remplacée ou complétée par un autre liquide. En particulier, dans le circuit de captage de chaleur l'eau est souvent addi¬ tionnée d'éthylène-glycol ou autre additif faisant fonction d'antigel. L'intérêt d'une pompe à chaleur réside dans le fait que l'énergie néces¬ saire pour son alimentation est inférieure à l'énergie restituée dans le cir¬ cuit de chauffage. On désigne par « coefficient de performance » (COP) le ratio entre l'énergie restituée et l'énergie consommée par le système, ratio qui peut atteindre typiquement une valeur de 5 avec les meilleurs systèmes actuellement disponibles sur le marché. Plus précisément, une pompe à chaleur comporte un bloc compresseur et deux échangeurs de chaleur reliés respectivement aux réseaux de cap- tage et de restitution de chaleur. Les échangeurs de chaleur sont par ail¬ leurs couplés au compresseur et au circuit frigorigène associé à ce der¬ nier, comprenant un condenseur, un détendeur et un évaporateur. Le compresseur concentre côté condenseur l'énergie captée et restitue côté évaporateur l'énergie à restituer au circuit de chauffage. La performance globale de la pompe à chaleur est d'autant meilleure que l'échange thermique est complet et que l'ensemble des actions du com¬ presseur et des échangeurs s'opèrent avec la meilleure isolation thermi¬ que possible vis-à-vis de l'environnement extérieur. Le compresseur, son circuit de fluide frigorigène associé ainsi que les deux échangeurs de chaleur sont regroupés en un même bloc fonctionnel, ci-après désigné « cœur de pompe à chaleur », qui constitue un ensemble intégré destiné à être par ailleurs associé aux différents éléments des cir¬ cuits de captage et de restitution de chaleur (tuyauterie, pompes de circu¬ lation, capteur thermostatique, etc.) ainsi qu'aux équipements d'alimenta- tion et de régulation du système.The invention relates to water / water type heat pumps. This equipment makes it possible to capture the thermal energy available in the air, in the upper layers of the earth or in open water, to concentrate this energy and to return it in this concentrated form (at a higher temperature) to supply a heating circuit with hot water. By "water / water" we mean a type of heat pump in which the heat collection circuit and the heat recovery circuit (heating) are both circuits in which a liquid circulates, as opposed to water systems. / air "or" air / air ", it being understood that, depending on the needs, the water may be replaced or supplemented by another liquid. In particular, in the heat capture circuit water is often addi¬ tioned ethylene glycol or other additive acting as antifreeze. The advantage of a heat pump lies in the fact that the energy required for its power supply is lower than the energy returned in the heating circuit. The term "coefficient of performance" (COP) refers to the ratio between the energy returned and the energy consumed by the system, a ratio that can typically reach a value of 5 with the best systems currently available on the market. More specifically, a heat pump comprises a compressor block and two heat exchangers respectively connected to the networks for collecting and recovering heat. The heat exchangers are, in addition, coupled to the compressor and the refrigerant circuit associated therewith, comprising a condenser, an expander and an evaporator. The compressor concentrates condenser side energy captured and restores the evaporator side energy to be returned to the heating circuit. The overall performance of the heat pump is all the better as the heat exchange is complete and all the actions of the com¬ presser and exchangers operate with the best thermal insulation possible vis-à-vis of the external environment. The compressor, its associated refrigerant circuit as well as the two heat exchangers are grouped together in one and the same functional block, hereinafter referred to as "heat pump core", which constitutes an integrated assembly intended to be associated with the various elements of heat recovery and recovery circuits (piping, circu¬ tion pumps, thermostatic sensor, etc. .) as well as system power and control equipment.
Dans les cœurs de pompe à chaleur proposés jusqu'à présent, les diffé¬ rents éléments sont reliés entre eux par des tubes assemblés selon les techniques usuelles bien connues des chauffagistes et frigoristes. Plus précisément, les liaisons entre compresseur et échangeurs, et entre échangeurs et prises d'entrée/sortie des réseaux de captage et de restitu¬ tion de chaleur, y sont réalisées au moyen de tubes en cuivre, assemblés par brasage.In the heat pump cores proposed so far, the various elements are interconnected by tubes assembled according to the usual techniques well known to heating and refrigeration technicians. More specifically, the connections between compressor and heat exchangers, and between heat exchangers and input / output outlets of the collection and heat recovery networks, are made by means of copper tubes, assembled by soldering.
Toutefois, dans l'application aux pompes à chaleur, l'utilisation de tubes en cuivre, et l'assemblage des tubes par brasage, n'est pas sans présen- ter certains inconvénients.However, in the application to heat pumps, the use of copper tubes, and the assembly of tubes by brazing, is not without certain disadvantages.
En premier lieu, le cuivre se caractérise par une grande conductibilité ther¬ mique, qui n'est pas recherchée dans cette application puisqu'elle est gé¬ nératrice de pertes par échanges thermiques avec l'environnement. En second lieu, les assemblages réalisés par brasage, s'ils garantissent une bonne étanchéité, ne sont pas d'une résistance mécanique et à la corrosion très élevée. En effet, comme on le sait, le brasage consiste à assembler des métaux différents par apport d'un métal tiers (brasure à l'argent, dans le cas d'un brasage fort) porté à une température supé¬ rieure à son point de fusion. Du fait que les éléments du compresseur sont généralement en acier noir et les échangeurs en acier noir ou acier inoxydable, et que ces éléments sont reliés entre eux par des tubes en cuivre, on va se trouver à l'endroit des liaisons brasées en présence de solutions de continuité acier/cuivre ou acier inox/cuivre, avec en outre in¬ terposition du métal d'apport. Or ces liaisons sont sujettes en provenance du compresseur à des vibra¬ tions qui conduiraient rapidement à des fuites ou même des détériorations dans le cas d'un assemblage trop rigide.In the first place, copper is characterized by high thermic conductivity, which is not sought after in this application since it generates losses by heat exchanges with the environment. Secondly, the assemblies made by brazing, if they guarantee a good seal, are not of a very high mechanical strength and corrosion. Indeed, as is known, brazing is to assemble different metals by providing a third metal (silver solder, in the case of a brazing) raised to a temperature above its point of fusion. Since the elements of the compressor are generally made of black steel and the exchangers are made of black steel or stainless steel, and these elements are connected to each other by copper tubes, we will find ourselves at the place of the brazed connections in the presence of continuity solutions steel / copper or stainless steel / copper, with in¬ terposition of the filler metal. But these connections are subject from the compressor vibra¬ tions that would lead quickly to leaks or even damage in the case of too rigid assembly.
Pour éviter cet écueil, les liaisons en cuivre sont généralement réalisées de manière à procurer à l'ensemble une certaine souplesse, grâce à des liaisons assez longues et/ou une géométrie particulière (lyres, serpentins, etc.) permettant de mieux disperser les contraintes résultant notamment de la propagation des vibrations dans les canalisations en cuivre. L'augmentation des longueurs de tubes a cependant pour effet d'augmen¬ ter la surface d'échange avec l'atmosphère ambiante, donc les pertes, et aussi d'augmenter inutilement le volume de gaz frigorigène du circuit du compresseur.To avoid this pitfall, the copper bonds are generally made so as to provide the whole with a certain flexibility, thanks to rather long connections and / or a particular geometry (lyres, coils, etc.) to better disperse the stresses resulting in particular from the propagation of vibrations in the copper pipes. Increasing the lengths of tubes, however, has the effect of increasing the exchange surface with the ambient atmosphere, thus the losses, and also unnecessarily increase the volume of refrigerant gas of the compressor circuit.
La présente invention a pour objet de remédier à ces inconvénients, en proposant un cœur de pompe à chaleur optimisé tant du point de vue du rendement que de la compacité et de la fiabilité de fonctionnement. Le cœur de pompe à chaleur de l'invention est un cœur de pompe de type eau/eau tel que décrit plus haut, c'est-à-dire comprenant, plus précisé¬ ment et de manière en elle-même connue : un bloc compresseur, compre¬ nant un circuit fermé chargé de fluide frigorigène avec compresseur, con¬ denseur, détendeur et évaporateur ; une prise d'entrée et une prise de sortie vers un réseau de captage de chaleur ; une prise d'entrée et une prise de sortie vers un réseau de restitution de chaleur ; un premier é- changeur de chaleur, couplé côté primaire à l'évaporateur du bloc com¬ presseur et côté secondaire aux prises du réseau de captage de chaleur ; et un second échangeur de chaleur, couplé côté primaire au condenseur du bloc compresseur et côté secondaire aux prises du réseau de restitu¬ tion de chaleur.The object of the present invention is to remedy these drawbacks by proposing an optimized heat pump core both from the point of view of efficiency and compactness and reliability of operation. The heat pump core of the invention is a pump core of water / water type as described above, that is to say comprising, more precisely and in a manner known in itself: a block compressor, comprising a closed circuit charged with refrigerant with compressor, con¬ denser, expander and evaporator; an input socket and an output socket to a heat collection network; an input socket and an output socket to a heat transfer network; a first heat exchanger, coupled on the primary side to the evaporator of the compressor block and the secondary side to the heat collection network taps; and a second heat exchanger, coupled on the primary side to the condenser of the compressor block and the secondary side to the outlets of the heat recovery network.
De façon caractéristique de l'invention, les tubulures de liaison entre les échangeurs de chaleur et le bloc compresseur, et/ou les tubulures de liai¬ son entre les échangeurs de chaleur et les prises des réseaux de captage et de restitution de chaleur sont des tubulures de liaison non brasées, for¬ mées par des tubes en acier inoxydable soudés.Characteristically according to the invention, the connection pipes between the heat exchangers and the compressor block, and / or the liai¬ son pipes between the heat exchangers and the catches of the collection and heat recovery networks are unbridged connection pipes, forged by welded stainless steel tubes.
En remplaçant les tubes en cuivre utilisés jusqu'à présent par des tubes en acier, et en remplaçant les assemblages brasés par des assemblages soudés, les diverses liaisons ainsi réalisées au sein du cœur de pompe à chaleur ne présentent plus de solution de continuité, ce qui leur procure une qualité de résistance mécanique - notamment aux vibrations - et une qualité de résistance à la corrosion incomparablement supérieures à ce qu'elles étaient avec des assemblages brasés. En effet, dans le cas d'un soudage, si celui-ci est bien réalisé, en termes de tenue mécanique et d'étanchéité le résultat est équivalent à celui du tube d'origine.By replacing the copper tubes used until now with steel tubes, and by replacing the brazed assemblies with welded joints, the various connections thus made within the heat pump core no longer present a continuity solution. which gives them a quality of mechanical resistance - especially to vibrations - and a quality of resistance to corrosion incomparably superior to what they were with brazed assemblies. Indeed, in the case of welding, if it is well done, in terms of mechanical strength and sealing the result is equivalent to that of the original tube.
En particulier, les vibrations engendrées par le compresseur ne peuvent pas entraîner de détérioration de ces assemblages, et la tenue mécani¬ que, la géométrie et la souplesse des tubes et des échangeurs en acier inoxydable peuvent être définies de façon à absorber sans rupture ces vibrations par des liaisons courtes et de faible diamètre, à l'opposé des liaisons en cuivre utilisées jusqu'à présent. Cette réduction dimensionnelle permet d'abaisser d'autant les échanges thermiques du fluide avec l'environnement, donc les pertes, ainsi que le volume de fluide frigorigène nécessaire. De plus, outre la moindre surface exposée, les échanges thermiques seront également réduits par le fait que l'acier est bien moins bon conducteur de chaleur que le cuivre et qu'aucune patte de fixation au châssis n'est plus nécessaire pour le main¬ tien des échangeurs (suppression des ponts thermiques lorsque les é- changeurs de chaleur sont essentiellement dépourvus de telles pattes). Il est ainsi possible d'augmenter notablement le coefficient de performan¬ ce de la pompe à chaleur, typiquement de 1 à 2 points, c'est-à-dire qu'il devient possible d'atteindre des valeurs de COP de l'ordre de 6 à 7, per¬ formances bien au-dessus des meilleurs systèmes proposés jusqu'à pré¬ sent.In particular, the vibrations generated by the compressor can not cause deterioration of these assemblies, and the mechanical strength, geometry and flexibility of the tubes and stainless steel heat exchangers can be defined so as to absorb without breaking these vibrations. by short links and small diameter, as opposed to the copper links used so far. This dimensional reduction makes it possible to lower the thermal exchanges of the fluid with the environment, thus the losses, as well as the volume of refrigerant required. In addition, in addition to the least exposed surface, heat exchange will also be reduced by the fact that steel is much less good heat conductor than copper and no bracket to the frame is no longer necessary for the main¬ heat exchangers (removal of thermal bridges when the heat exchangers are essentially free of such lugs). It is thus possible to significantly increase the coefficient of performance of the heat pump, typically from 1 to 2 points, that is to say that it becomes possible to achieve COP values of the order from 6 to 7, performances far above the best systems proposed until now.
Le soudage est avantageusement réalisé par soudage TIG orbital, qui est une technique parfaitement maîtrisée pouvant être mise en œuvre de fa- çon automatique, donc avec un contrôle précis des différents paramètres et une excellente reproductibilité, conduisant ici encore à un accroisse¬ ment de la fiabilité d'ensemble de l'appareil. De plus, le soudage automa¬ tique TIG orbital permet de limiter au minimum l'élévation de température du corps de compresseur, évitant ainsi toute fragilisation de celui-ci. De préférence, les échangeurs de chaleur sont des échangeurs tubulaires en acier inoxydable.The welding is advantageously performed by orbital TIG welding, which is a perfectly controlled technique that can be implemented automatically, thus with precise control of the various parameters and excellent reproducibility, again leading to an increase in the overall reliability of the device. In addition, automatic welding TIG orbital allows to minimize the temperature rise of the compressor body, thus avoiding any embrittlement thereof. Preferably, the heat exchangers are stainless steel tubular exchangers.
Ce type d'échangeur, qui convient parfaitement à une pompe à chaleur selon l'invention où les différentes liaisons sont des liaisons soudées, peut remplacer avantageusement les échangeurs à plaques assemblés par brasage jusqu'à présent généralement utilisés dans le domaine des pom- pes à chaleur. Même s'ils assurent un bon échange thermique, les échan- geurs à plaques sont en effet fragiles et ne supportent pas longtemps une eau chargée en sels minéraux, qui peut provoquer un bouchage par ac¬ cumulation de dépôts ou d'impuretés solides. Enfin, leur tenue en pré- sence de vibrations continues reste limitée.This type of exchanger, which is perfectly suitable for a heat pump according to the invention where the various connections are soldered connections, can advantageously replace the solder-assembled plate heat exchangers hitherto generally used in the field of heat pumps. heat pes. Even if they ensure a good heat exchange, the plate exchangers are indeed fragile and do not long support a water loaded with mineral salts, which can cause clogging by accumulation of deposits or solid impurities. Finally, their behavior in the presence of continuous vibrations remains limited.
Du fait de l'accroissement considérable de fiabilité, il devient inutile de mé¬ nager une possibilité d'accès aux différents éléments internes du cœur de pompe après fabrication. Ces différents éléments (bloc compresseur, é- changeurs de chaleur, tubulures de liaison entre échangeurs et bloc com- presseur, et tubulures de liaison entre échangeurs et prises des réseaux de captage et de restitution de chaleur) peuvent donc être confinés dans une enceinte formant un unique bloc fonctionnel étanche et isotherme. Cette enceinte étanche de confinement peut en particulier comprendre une base support, supportant le bloc compresseur et les échangeurs de chaleur, et un capot rapporté sur cette base support, la base support et le capot étant solidarisés entre eux de manière permanente, par exemple par soudage s'ils sont en métal. Il est entendu que cette "base support" peut constituer tout ou partie de l'une quelconque ou de certaines de fa¬ ces de l'ensemble, et pas seulement sa partie inférieure. L'espace libre résiduel de l'enceinte de confinement peut être rempli d'un matériau isolant, la base support comportant alors un orifice occultable d'introduction de ce matériau isolant.Because of the considerable increase in reliability, it becomes unnecessary to man¬ a possibility of access to the various internal elements of the pump core after manufacture. These various elements (compressor block, heat exchangers, connection pipes between heat exchangers and compressor block, and connection pipes between heat exchangers and catches of heat capture and return networks) can therefore be confined in a chamber forming a unique waterproof and isothermal functional block. This sealed confinement enclosure may in particular comprise a support base, supporting the compressor block and the heat exchangers, and a cover attached to this support base, the support base and the cover being permanently joined to each other, for example by welding if they are metal. It is understood that this "base support" may constitute all or part of any one or some fa¬ these of the whole, and not only its lower part. The residual free space of the confinement chamber may be filled with an insulating material, the support base then comprising an occultable orifice for introducing this insulating material.
L'atmosphère interne de l'enceinte de confinement peut être sous vide, ou remplie d'un gaz sec isolant, la base support comportant alors un orifice occultable, en communication avec ladite atmosphère, pour l'application du vide ou l'introduction du gaz.The internal atmosphere of the confinement chamber may be under vacuum, or filled with an insulating dry gas, the support base then comprising an occultable orifice, in communication with said atmosphere, for the application of the vacuum or the introduction of the gas.
De préférence, les prises du réseau de captage de chaleur, les prises du réseau de restitution de chaleur, et le(s)dit(s) orifice(s) occultable(s) sont regroupés sur la base support. L'invention couvre également, en tant que telle, une pompe à chaleur comprenant, en combinaison, un cœur de pompe tel que ci-dessus asso¬ cié à des organes de couplage, comprenant au moins un circulateur, à un circuit de captage de chaleur et à un circuit de restitution de chaleur, ainsi que des organes de régulation thermique, et des organes d'alimentation électrique de l'ensemble. 0Preferably, the catches of the heat collection network, the outlets of the heat transfer network, and the said occultable port (s) are grouped on the support base. The invention also covers, as such, a heat pump comprising, in combination, a pump core as above asso¬ cied to coupling members, comprising at least one circulator, a sensing circuit of heat and a heat recovery circuit, as well as thermal regulating members, and power supply members of the assembly. 0
On va maintenant décrire un exemple de pompe à chaleur réalisée selon les enseignements de l'invention, en référence à la figure unique annexée qui est une vue schématique, en perspective cavalière, des différents élé¬ ments constituant ce cœur de pompe.An example of a heat pump made according to the teachings of the invention will now be described, with reference to the single appended figure which is a schematic view, in cavalier perspective, of the various elements constituting this pump core.

Sur la figure, la référence 10 désigne le bloc compresseur, qui est un en¬ semble avec un circuit fermé, chargé en fluide frigorigène, comprenant un compresseur 11 , un évaporateur 12, un condenseur 13 et un détendeur 14. Le moteur du compresseur est par exemple un moteur électrique ali- mente de l'extérieur par le secteur.In the figure, reference numeral 10 denotes the compressor block, which is an en¬ appears with a closed circuit, charged with refrigerant, comprising a compressor 11, an evaporator 12, a condenser 13 and a pressure regulator 14. The compressor motor is for example an electric motor supplied from outside by the mains.
Un premier échangeur de chaleur 20 est couplé côté primaire à l'évapora- teur 12 du bloc compresseur 10 via deux liaisons 21 et 22. Côté secon¬ daire, il est relié à des prises 23, 24 d'entrée et de sortie de fluide desti¬ nées à être reliées à un réseau de captage de chaleur ; les liaisons aux prises 23, 24 sont réalisées par des tubulures 25, 26.A first heat exchanger 20 is coupled on the primary side to the evaporator 12 of the compressor block 10 via two links 21 and 22. On the second side, it is connected to sockets 23, 24 for inlet and outlet of fluid desti¬ to be connected to a heat collection network; the connections to the sockets 23, 24 are made by pipes 25, 26.
Un second échangeur de chaleur 30 est couplé côté primaire au conden¬ seur 13 du bloc compresseur 10 via deux liaisons 31 et 32. Côté secon¬ daire, il est relié à des prises 33, 34 d'entrée et de sortie de fluide desti¬ nées à être reliées à un réseau de restitution de chaleur (réseau de chauf- fage) ; les liaisons aux prises 33, 34 sont réalisées par des tubulures 35, 36.A second heat exchanger 30 is coupled on the primary side to the condenser 13 of the compressor unit 10 via two links 31 and 32. On the second side, it is connected to sockets 33, 34 for the inlet and the outlet of the fluid. to be connected to a heat transfer network (heating network); the connections to the taps 33, 34 are produced by tubes 35, 36.
Les échangeurs 20 et 30 sont de préférence des échangeurs tubulaires torsadés en acier inoxydable soudé, dont la taille est adaptée à la puis¬ sance du compresseur pour garantir un échange optimum tant vers le cir- cuit de chauffage que depuis le circuit de captage de chaleur.The exchangers 20 and 30 are preferably twisted tubular heat exchangers made of welded stainless steel, the size of which is adapted to the power of the compressor to guarantee optimum exchange both towards the heating circuit and from the heat capture circuit. .
De façon caractéristique de l'invention, les liaisons 21 , 22, 31 , 32 entre le compresseur 10 et les échangeurs de chaleur 20 et 30, ainsi que les liai¬ sons 25, 26, 35, 36 entre les échangeurs 20 et 30 et les prises 23, 24, 33, 34 d'entrée et de sortie des réseaux de captage et de restitution de cha- leur, sont assurées au moyen de tubes en acier inoxydable soudés. Le diamètre de ces tubes est optimisé pour assurer cette liaison sans créer d'entrave pour le fluide (fluide frigorigène, ou fluide circulant dans les ré¬ seaux), avec une longueur et une géométrie étudiées pour réaliser cette liaison par le plus court chemin possible. De plus, grâce à l'excellente so- lidité mécanique des liaisons soudées, les échangeurs peuvent être sim¬ plement suspendus par les tubes 21 , 22, 25, 26 (ou 31 , 32, 35, 36, res¬ pectivement), qui les retiennent en place sans qu'il soit nécessaire de pré¬ voir pour les soutenir des pattes de fixation au châssis ou moyens analo¬ gues, générateurs de ponts thermiques. Un tube de petit diamètre 16, qui peut également être réalisé en acier inoxydable en forme de spire ou de multispire, assure un accès étanche pour le chargement du compresseur en fluide frigorigène et le contrôle de cette charge. À l'extérieur de l'enceinte, ce tube en acier inoxydable pour¬ ra être prolongé d'un tube en cuivre permettant la jonction à la réserve de gaz frigorigène par des méthodes habituellement utilisées par les frigoris- tes.In a characteristic manner of the invention, the connections 21, 22, 31, 32 between the compressor 10 and the heat exchangers 20 and 30, as well as the connections 25, 26, 35, 36 between the exchangers 20 and 30 and Inlets and outlets 23, 24, 33, 34 for input and output from heat capture and return networks are provided by means of welded stainless steel tubes. The The diameter of these tubes is optimized to ensure this connection without creating any obstacle for the fluid (refrigerant, or fluid flowing in the networks), with a length and a geometry studied to achieve this connection by the shortest path possible. Moreover, thanks to the excellent mechanical strength of the welded connections, the exchangers can be simply suspended by the tubes 21, 22, 25, 26 (or 31, 32, 35, 36, respectively), which they are held in place without the need to pre¬ see to support the mounting brackets to the frame or analog means, generators thermal bridges. A small diameter tube 16, which may also be made of spiral or multispire-shaped stainless steel, provides sealed access for refrigerant charging of the compressor and control of this charge. Outside the enclosure, this stainless steel tube may be extended by a copper tube allowing the connection to the refrigerant gas reserve by methods usually used by refrigerators.
Les différents éléments du cœur de pompe à chaleur que l'on vient de dé¬ crire sont regroupés à l'intérieur d'un boîtier 40 constitué d'une base sup¬ port 41 et d'un capot 42. Avantageusement, toutes les entrées et sorties utiles et tous les accès aux éléments du cœur de pompe sont regroupés au niveau de la base support 41 , notamment les prises 23, 24, 33, 34 aux réseaux de captage et de restitution de chaleur. On y trouve également la traversée 43 pour l'alimentation électrique du compresseur 11 , ainsi qu'un orifice occultable 44 permettant la communication avec Ie volume intérieur de l'enceinte une fois le capot 42 fermé, et une traversée 45 pour la con¬ duite 16 de charge du fluide frigorigène. Sur la figure 1 la base support occupe toute la partie inférieure de l'ensemble. Mais elle peut aussi bien occuper tout ou partie de l'une quelconque ou de certaines faces de l'en¬ semble, suivant le besoin dans la réalisation de la pompe à chaleur. Le capot 42 peut donc être aisément rendu étanche, formé d'une seule pièce, par exemple métallique, sans aucune traversée. Il peut être fixé de façon étanche à la base support 41 pour constituer une enveloppe isolant complètement le coeur de pompe à chaleur de son environnement. Lors¬ que le capot et la base support sont tous deux réalisés en métal, cette fixation étanche peut même être avantageusement réalisée par soudage des deux éléments de manière à constituer un bloc fonctionnel unique, non démontable. D'autres solutions de solidarisation permanente peuvent être envisagées, par exemple un collage, lorsque capot et/ou base sup¬ port ne sont pas réalisés en un matériau métallique apte au soudage. Avantageusement, après fermeture de l'enveloppe, on introduit par l'orifi¬ ce 44 une matière isolante venant remplir complètement le volume inté¬ rieur du cœur de pompe, par exemple une matière pulvérulente ou une mousse expansible, qui va minimiser les échanges thermiques non sou¬ haitables et accroître d'autant les performances du système. En outre, ce garnissage réduit la transmission des vibrations mécaniques et acousti¬ ques produites par le compresseur vers l'extérieur. Après remplissage, l'enceinte étanche peut enfin être tirée au vide ou remplie d'un gaz sec procurant des caractéristiques d'isolement thermique meilleures que l'air, par exemple l'argon ou l'hexafluorure de soufre. Enfin, pour le cas où la base support est constituée de la face inférieure et dans la mesure où les tubes 26 et 36 conduisant aux points hauts respec¬ tifs des circuits de captage de chaleur et de chauffage ne sont pas cou¬ dés, il est possible d'y glisser des systèmes de purge comprenant un pur¬ geur automatique 46 relié à une conduite 48 se terminant en partie basse, hors du bloc 40, par un évent 50 monté sur un manchon 52 emboîté à l'embouchure de la conduite homologue 26 ou 36. Ces systèmes de purge, mis en place depuis l'extérieur (comme on peut le voir sur la vue éclatée de la figure), peuvent être aisément remplacés plus tard, si né¬ cessaire. The various elements of the heat pump core that have just been described are grouped together inside a housing 40 consisting of a sup¬ base 41 and a hood 42. Advantageously, all the inputs and useful outputs and all access to the elements of the pump core are grouped at the support base 41, including the sockets 23, 24, 33, 34 to the heat capture and recovery networks. There is also the crossing 43 for the power supply of the compressor 11, and an occultable orifice 44 for communication with the interior volume of the enclosure once the cover 42 closed, and a passage 45 for con¬ duite 16 charging the refrigerant. In Figure 1 the support base occupies the entire lower part of the assembly. But it can also occupy all or part of any one or some sides of en¬ seems, as needed in the realization of the heat pump. The cover 42 can therefore be easily sealed, formed in one piece, for example metal, without any crossing. It can be sealed to the support base 41 to form an envelope completely isolating the heat pump core from its environment. When the cover and the support base are both made of metal, this waterproof fastening can even be advantageously achieved by welding. of the two elements so as to constitute a single functional block, not removable. Other permanent joining solutions may be envisaged, for example gluing, when the hood and / or base sup¬ port are not made of a metal material suitable for welding. Advantageously, after closure of the casing, an insulating material is introduced through the ori fi cation 44 to completely fill the internal volume of the pump core, for example a pulverulent material or an expandable foam, which will minimize heat exchange. unsustainable and increase the performance of the system. In addition, this lining reduces the transmission of mechanical and acoustic vibrations produced by the compressor to the outside. After filling, the sealed enclosure can finally be drawn to vacuum or filled with a dry gas providing better thermal insulation characteristics than air, for example argon or sulfur hexafluoride. Finally, in the case where the support base is made up of the lower face and insofar as the tubes 26 and 36 leading to the respective high points respec¬ tif heat and heating capture circuits are not cou¬ dice, it is It is possible to slide purge systems therein comprising an automatic purifier 46 connected to a pipe 48 terminating in the lower part, outside the block 40, by a vent 50 mounted on a sleeve 52 fitted at the mouth of the homologous pipe. 26 or 36. These purge systems, installed from the outside (as can be seen in the exploded view of the figure), can be easily replaced later, if necessary.
