Abstract

The invention pertains to improvements brought to a heating facility which includes an associated absorbing heat pump cycle. The facility is designed for direct thermosiphon heating of the absorption solution to be regenerated upon contact with a panelling (15) which surrounds the combustion chamber (9). The separation of the solution to be regenerated is performed inside a separation column (14) which is connected to a dephlegmator (16) which improves the yield of the separation, the yield of the absorbing cycle and the recovery yield of heat supplied by the burner. Furthermore a heat exchanger (8) enables the operation of the facility with a de-activation of the absorbing cycle. The invention applies especially to central heating and to the heating of hygienic water.

Description

La présente invention a pour objet des perfectionnements à une installation de chauffage équipée d'une pompe à chaleur à absorption.The present invention relates to improvements in a heating installation equipped with an absorption heat pump.

Dans certaines installations de chauffage d'un fluide, teL par exemple que de l'eau, en particulier pour Le chauffage de bâtiments et La production d'eau chaude sanitaire, installations comprenant au moins un brûleur à combustible solide, liquide et/ou gazeux produisant des "fumées" à température relativement élevée, on utilise parfois une pompe à chaleur à absorption afin d'améliorer Le rendement thermique du chauffage.In certain installations for heating a fluid, for example water, in particular for heating buildings and producing domestic hot water, installations comprising at least one solid, liquid and / or gaseous fuel burner producing relatively high temperature "fumes", an absorption heat pump is sometimes used in order to improve the thermal efficiency of the heating.

Dans un teL cas habituellement, Le brûleur sert à faire bouillir La solution d'absorption utilisée dans Le cycle d'absorption de La pompe à chaleur de façon à séparer les constituants de La solution et régénérer Le fluide d'absorption utilisé dans Le cycle.In such a case usually, the burner is used to boil the absorption solution used in the absorption cycle of the heat pump so as to separate the constituents of the solution and regenerate the absorption fluid used in the cycle.

Au niveau de l'échange de chaleur fumées/solution d'absorption à régénérer, Le rendement est médiocre du fait que compte tenu des conditions de l'échange thermique les fumées quittent l'installation à une température généralement élevée supérieure à 200°C entrainant à La cheminée de grandes quantités d'énergie qui sont perdues.At the level of the heat exchange of smoke / absorption solution to be regenerated, the yield is poor because, taking into account the conditions of the heat exchange, the smoke leaves the installation at a generally high temperature above 200 ° C. à The chimney large amounts of energy that are lost.

Dans La plupart des cas cette situation défavorable est tolérée car au niveau du cycle de La pompe à chaleur on récupère dans Le milieu ambiant au niveau de l'évaporateur du cycle nettement plus d'énergie qu'on en a laissé échapper à La cheminée, de sorte que Le rendement global de l'installation apparaît relativement bon. Ceci n'est cependant vrai que si les conditions de fonctionnement de L'évaporateur sont satisfaisantes, c'est-à-dire généralement si Le niveau de La "source froide" dans laquelle est "pompée" La chaleur délivrée à l'installation est suffisamment élevé. Ce phénomène bien connu conduit du reste les installateurs à installer en parallèle sur l'installation de chauffage équipée d'une pompe à chaleur une chaudière de type classique qui chauffera directement Le fluide à chauffer lorsque les conditions d'exploitation de La source froide seront défavorables (généralement- par temps froid plus particulièrement si l'évaporateur emprunte sa chaleur à l'air ambiant)In most cases this unfavorable situation is tolerated because at the level of the heat pump cycle we recover in the ambient environment at the level of the cycle evaporator much more energy than we left escape the chimney, so that the overall performance of the installation appears relatively good. This is only true, however, if the operating conditions of the evaporator are satisfactory, that is to say generally if the level of the "cold source" into which the heat supplied to the installation is "pumped" is high enough. This well known phenomenon leads the installers to install in parallel on the heating installation equipped with a heat pump a boiler of conventional type which will directly heat the fluid to be heated when the operating conditions of the cold source are unfavorable. (usually- especially in cold weather if the evaporator borrows its heat from the ambient air)

De façon à réduire les pertes de chaleur à la cheminée, il a également été proposé de disposer des échangeurs récupérateurs de chaleur sur le circuit des fumées, lesquels échangeurs récupérateurs seront en échange thermique avec le fluide à chauffer. En pratique, cependant ces échangeurs ne donnent pas satisfaction, essentiellement pour les deux raisons suivantes.

  • 1) Le surcoût de l'installation que leur utilisation entraine n'est pas du point de vue économique rentable;
  • 2) l'aménagement de circuits d'échange, nécessitant de longues dimensions de canalisations fait qu'on reperd par pertes en ligne dans ces canalisations la plus grande partie de la chaleur que l'on a tenté de récupérer.
In order to reduce the heat losses to the chimney, it has also been proposed to have heat recovery exchangers on the smoke circuit, which recovery heat exchangers will be in heat exchange with the fluid to be heated. In practice, however, these exchangers are not satisfactory, essentially for the following two reasons.
  • 1) The additional cost of the installation that their use entails is not economically profitable;
  • 2) the arrangement of exchange circuits, requiring long dimensions of pipes, means that most of the heat that we have tried to recover is lost by losses in line in these pipes.

Dans la demande de brevet antérieure N° 82 19510 déposée le 22 novembre 1982 par le même demandeur, on a proposé une installation perfectionnée permettant de résoudre certaines des difficultés exposées.In prior patent application No. 82 19510 filed on November 22, 1982 by the same applicant, an improved installation was proposed which makes it possible to resolve some of the difficulties exposed.

A cet effet dans cette demande antérieure, l'échangeur pour bouilleur de pompe à chaleur comprend deux étages disposés en série, le premier formant bouilleur servant à porter à température adéquate la solution d'absorption, le second formant récupérateur servant à réchauffer le fluide de chauffage au voisinage de son entrée dans l'installation. Les deux échangeurs sont constitués de façon originale par deux bitubes disposés en série, le tube intérieur des deux bitubes servant de passage de sortie pour les fumées produites dans la chambre de combustion de l'installation. En outre une connexion est prévue au niveau du premier échangeur à l'endroit où la solution à régénérer quitte cet échangeur après chauffage, cette connexion débouchant dans un ballon séparateur dans lequel s'effectue la séparation de la solution enrichie volatile et de la solution appauvrie plus lourde en vue de l'utilisation de ces deux solutions séparées dans le cycle d'absorption de l'installation.To this end in this previous application, the heat pump boiler exchanger comprises two stages arranged in series, the first forming a boiler serving to bring the absorption solution to the appropriate temperature, the second forming a recuperator serving to heat the fluid of heating in the vicinity of its entry into the installation. The two exchangers are constituted in an original way by two twin tubes arranged in series, the inner tube of the two twin tubes serving as an outlet passage for the fumes produced in the combustion chamber of the installation. In addition, a connection is provided at the level of the first exchanger at the place where the solution to be regenerated leaves this exchanger after heating, this connection opening into a separator flask in which the separation of the volatile enriched solution and the depleted solution takes place. heavier for the use of these two separate solutions in the absorption cycle of the installation.

La présente invention utilise les principes généraux de cette demande antérieure à laquelle elle apporte des perfectionnements spécifiques assurant une mise en oeuvre bien plus "performante" et une plus grande souplesse d'emploi.The present invention uses the general principles of this earlier application to which it brings specific improvements ensuring much more "efficient" implementation and greater flexibility of use.

A cet effet, une installation de chauffage d'un fluide tel par exemple que de l'eau, en particulier pour le chauffage de bâtiments et la production d'eau chaude sanitaire conforme à l'invention, du type comprenant au moins un brûleur à combustible solide, liquide et/ou gazeux produisant des "fumées" à température relativement élevée comprenant un premier échangeur pour bouilleur de pompe à chaleur et un deuxième échangeur récupérateur placé en série avec le premier et servant à chauffer ledit fluide, ledit premier échangeur communiquant avec un séparateur dans lequel s'effectue la séparation du "distillat" et du "résidu". de la solution d'absorption à régénérer après travail dans le cycle de l'installation, se caractérise en ce que ledit brûleur comporte une chambre de combustion en contact de laquelle est placé un chemisage qui communique directement avec la partie d'une colonne de séparation formant le séparateur précité, ladite colonne étant placée juste au-dessus et danslaquelle sont introduits les retours de la solution d'absorption à régénérer. Pour des facilités d'expression et de compréhension du texte, on dénommera dans la suite "distillat" la partie plus volatile ou solution "enrichie" de la solution d'absorption après sa régénération et "résidu"'la partie plus lourde constituant la solution "appauvrie" de la solution d'absorption après sa régénération.To this end, an installation for heating a fluid such as for example water, in particular for heating buildings and producing domestic hot water according to the invention, of the type comprising at least one burner with solid, liquid and / or gaseous fuel producing "fumes" at relatively high temperature comprising a first exchanger for a heat pump boiler and a second recuperator exchanger placed in series with the first and serving to heat said fluid, said first exchanger communicating with a separator in which the separation of the "distillate" and the "residue" takes place. of the absorption solution to be regenerated after work in the installation cycle, is characterized in that said burner comprises a combustion chamber in contact with which is placed a liner which communicates directly with the part of a separation column forming the aforementioned separator, said column being placed just above and into which are introduced the returns of the absorption solution to be regenerated. For ease of expression and understanding of the text, hereinafter "distillate" the more volatile part or solution "enriched" of the absorption solution after its regeneration and "residue" the heavier part constituting the solution "depleted" of the absorption solution after its regeneration.

En opérant de la façon ci-dessus indiquée on améliore considérablement les conditions de fonctionnement de l'installation car cela permet non seulement d'améliorer la récupération de la chaleur au niveau du brûleur et au profit de l'installation, mais également d'élever la température de la solution d'absorption à régénérer et d'améliorer simultanément l'efficacité de la séparation, donc le rendement thermique du cycle d'absorption.By operating in the manner indicated above, the operating conditions of the installation are considerably improved as this not only improves heat recovery at the burner and for the benefit of the installation, but also increases the temperature of the absorption solution to be regenerated and simultaneously improve the efficiency of the separation, therefore the thermal efficiency of the absorption cycle.

Avantageusement ledit chemisage est divisé en deux chambres contiguës,la première dans laquelle sont admis lesdits retours de la solution à régénérer avant d'être introduits dans ladite colonne de séparation, la seconde qui communique directement avec la solution présente à la base de ladite colonne par au moins une large ouverture favorisant les échanges thermiques par thermosiphon, une telle conception de la construction, de technique simple assurant naturellement et automatiquement un excellent chauffage homogène de la solution d'absorption à régénérer directement au niveau de la base de la colonne de séparation.Advantageously, said lining is divided into two adjoining chambers, the first in which said returns of the solution to be regenerated are admitted, before being introduced into said separation column, the second which communicates directly with the solution present at the base of said column by at least one large opening favoring heat exchanges by thermosyphon, such a construction design, of simple technique naturally and automatically ensuring excellent homogeneous heating of the absorption solution to regenerate directly at the base of the separation column.

Dans l'exemple de réalisation illustré le chemisage 15, est divisé par une cloison 18 en deux chambres respectivement 19 et 20. La chambre 19 est en communication par deux conduits de section relativement importante 21, 22 avec la base de la colonne 14.

The chamber 19 is in communication by two relatively large cross-sections 21, 22 with the base of the column 14. In this way it is established under the effect of the heating which takes place in the combustion chamber 17 efficient circulation in thermosyphon of the solution to be regenerated present up to the level marked 23 in column 14. This gives good homogenization of the temperature of the solution to be regenerated in column 14.

La plus grande partie du chemisage 20 entourant la chambre de combustion 17 reçoit, comme il apparaitra plus clairement plus loin les retours de la solution d'absorption provenant de l'absorbeur 5 et après qu'ils auront traversé l'échangeur de chaleur 10 en vue de leur admission par le conduit 24 dans la colonne 14. De cette façon on obtient un chauffage plus efficace et à plus haute température de la solution d'absorption améliorant le processus de régénération de la qualité duquel dépend en grande partie le rendement du cycle d'absorption.Most of the lining 20 surrounding the combustion chamber 17 receives, as will appear more clearly below, the returns of the absorption solution coming from the absorber 5 and after they have passed through the heat exchanger 10 in view of their admission by the conduit 24 in column 14. In this way a more efficient and higher temperature heating of the absorption solution is obtained, improving the regeneration process of the quality on which the yield of the absorption cycle largely depends.

Comme il apparaît à la figure 2 le conduit 24 débouche par son orifice supérieur en 25 sensiblement à mi-hauteur de la colonne 14, laquelle comporte un certain nombre de chicanes 26, 27, 28 formant plateaux simplifiés de distillation dans cette colonne. Ainsi est obtenué une séparation plus efficace entre le "distillat" et le "résidu" séparés dans cette colonne à partir de la solution d'absorption provenant de l'absorbeur 5. Ainsi est également réduit l'entraînement par le distillat de fractions de résidus liquides sous forme de fines gouttelettes.As it appears in FIG. 2, the conduit 24 opens through its upper orifice 25 at substantially mid-height of the column 14, which comprises a number of baffles 26, 27, 28 forming simplified distillation plates in this column. Thus a more efficient separation is obtained between the "distillate" and the "residue" separated in this column from the absorption solution coming from the absorber 5. This also reduces the entrainment by the distillate of residue fractions liquids in the form of fine droplets.

Le résidu liquide sort de la colonne de séparation par le conduit 29 en base de colonne, tandis que le distillat sort en haut de colonne par le conduit 30.The liquid residue leaves the separation column through line 29 at the base of the column, while the distillate leaves at the top of the column through line 30.

,On se référera maintenant aux . figures 3 et 4 pour décrire la réalisation du "déflegmateur"., We will now refer to. Figures 3 and 4 to describe the implementation of the "de-phlegmator".

Les distillats sortant de la colonne 14 par le conduit 30 entrent dans le déflegmateur 16 à la partie supérieure d'un volume 31 ménagé entre la paroi 32 cylindrique circulaire verticale du déflegmateur 16, et une paroi 33 concentrique plus interne. A.1 'intérieur du volume 31 est également disposée une hélice tubulaire 34 dans laquelle circule comme indiqué par les flèches le fluide à chauffer formant fluide réfrigérant pénétrant dans le déflegmateur par le conduit 35 et en sortant par le-conduit 36 qui forme le départ chauffage de l'installation.The distillates leaving the column 14 through the conduit 30 enter the deflegmator 16 at the upper part of a volume 31 formed between the vertical circular cylindrical wall 32 of the dephlegmator 16, and a more internal concentric wall 33. A.1 'inside the volume 31 is also arranged a tubular helix 34 in which circulates as indicated by the arrows the fluid to be heated forming a refrigerant entering the de-phlegmator through the conduit 35 and leaving through the conduit 36 which forms the start heating of the installation.

Les distillats introduits en 30 dans le déflegmateur sont donc canalisés selon un trajet hélicoïdal périphérique descendant à contre-courant avec le fluide à chauffer parcourant l'hélice 34 et débochentvers la base de l'appareillage dans le volume repéré 37. Les distillats subissent ainsi à la fois un effet de centrifugation et un effet de réfrigération qui tendent à condenser les parties de résidu entrainées avec . les distillats et à les séparer des distillats plus légers. Dans ces conditions, les résidus condensés s'échappent du déflegmateur par le conduit 38 situé à la base de l'appareil tandis que les distillats sous forme gazeuse s'échappent de l'appareil par le conduit 39 dont le débouché est placé en 40 en partie haute de l'appareil.The distillates introduced at 30 into the de-phlegmator are therefore channeled along a peripheral helical path descending against the current with the fluid to be heated traversing the propeller 34 and unblock towards the base of the apparatus in the volume marked 37. The distillates are thus subjected to both a centrifugation effect and a refrigeration effect which tend to condense the parts of residue entrained with. distillates and to separate them from lighter distillates. Under these conditions, the condensed residues escape from the de-phlegmator through the conduit 38 located at the base of the apparatus while the distillates in gaseous form escape from the apparatus through the conduit 39, the outlet of which is placed at 40 in upper part of the appliance.

Comme il apparaît à la figure 1 les résidus séparés et recueillis en.38 dans le déflegmateur sont retournés à la colonne de séparation 14 vers la partie haute de cette colonne. De cette façon, on améliore très notablement la séparation de la solution d'absorption en ses distillats légers et résidus lourds, ce qui améliore le fonctionnement du cycle d'absorption.As it appears in figure 1 the separated residues and collected in 38 in the de-phlegmator are returned to the separation column 14 towards the upper part of this column. In this way, the separation of the absorption solution into its light distillates and heavy residues is very markedly improved, which improves the functioning of the absorption cycle.

En faisant référence maintenant aux figures 5 et 6, on aperçoit une implantation particulièrement efficace sur le plan thermique et commode sur le plan de la compacité de l'installation.Referring now to Figures 5 and 6, we see a particularly efficient layout thermally and convenient in terms of compactness of the installation.

On voit que la colonne de séparation 14, le déflegmateur 16, les échangeurs de chaleur 7 et 8 ont tous été logés à l'intérieur des deux hélices bitubes constituant l'échangeur de chaleur 10 pour le bouilleur de la pompe à chaleur et l'échangeur de chaleur 11 formant récupérateur de chaleur pour le fluide 'à chauffer. De cette façon sont améliorés les échanges thermiques dans l'installation, tous les échangeurs "chauds" étant placés à l'intérieur des deux échangeurs chauds 10,11.It can be seen that the separation column 14, the de-phlegmator 16, the heat exchangers 7 and 8 have all been housed inside the two twin-tube propellers constituting the heat exchanger 10 for the heat pump boiler and the heat exchanger 11 forming a heat recovery unit for the fluid to be heated. In this way the heat exchanges in the installation are improved, all the "hot" exchangers being placed inside the two hot exchangers 10, 11.

L'absorbeur 5 et le condenseur 2 trouvent leur place à l'extérieur des échangeurs 10,11, l'ensemble de l'installation, à l'exclusion de l'évaporateur 4 pouvant ainsi être logé dans une enveloppe formant habillage extérieur (non représentée)The absorber 5 and the condenser 2 find their place outside the exchangers 10, 11, the entire installation, excluding the evaporator 4, which can thus be housed in an envelope forming an external covering (not represented)

En faisant maintenant référence plus particulièrement aux figures 1 et 5, on décrira le fonctionnement de l'installation et les différents circuits de circulation.Referring now more particularly to FIGS. 1 and 5, the operation of the installation and the various circulation circuits will be described.

1) Circulation des distillats formant fluide calo- gène.1) Circulation of distillates forming heat transfer fluid.

Les distillats sont produits comme mentionnés ci-dessus dans la colonne de séparation 14 à partir de la solution d'absorption provenant de la colonne d'absorption 5. Les distillats s'échappent en tête de la colonne 14 par le conduit 30 pénétrant dans le déflegmateur 16. Après passage dans le déflegmateur qui assure la centrifugation et un refroidissement à contre courant avec le fluide à chauffer, les distillats débarrassés de leur "humidité" (les parties lourdes de "résidu" entrainées étant retournées à la colonne 14 par le conduit 38) sont amenés par le conduit 39 à l'intérieur du condenseur 2 refroidi à contre-courant par le circuit de fluide à chauffer dans lequel s'effectue la condensation. Les distillats condensés sont alors admis par le conduit 41 dans le détendeur 3 dans lequel s'effectue leur détente et refroidissement consécutif. Ils se réchauffent dans l'évaporateur 4 qui peut être un échangeur -à air échangeant de la chaleur avec le milieu ambiant ou par exemple à eau échangeant de la chaleur avec une eau résiduaire. C'est au niveau de cet appareil, comme il est connu que s'effectue l'emprunt de la chaleur au milieu extérieur. Les distillats ainsi détendus réchauffés à la sortie de l'évaporâteur 4 pénètrent par le conduit 43 en haut de la colonne d'absorption 5. Dans cette colonne, les distillats sont absorbés par les résidus lourds amenés par le conduit 44 dans l'absorbeur etauxquels ils se mélangent en libérant de la chaleur, laquelle est échangée en partie avec le fluide à chauffer comme il sera décrit ci-après en relation avec ce circuit. La solution de mélange quitte l'absorbeur par le conduit 45 d'où elle est reprise par la pompe 6 pour être ramenée après traversée de l'échangeur de chaleur 7 en contre courant avec les résidus chauds provenant de la colonne 14, avant de pénétrer dans l'échangeur 10 puis la chambre 20 formée autour de la chambre de combustion 17 avant d'être introduite dans la colonne de séparation 14 par le conduit 24.The distillates are produced as mentioned above in the separation column 14 from the absorption solution coming from the absorption column 5. The distillates escape at the top of the column 14 through the conduit 30 entering the de-phlegmator 16. After passing through the de-phlegmator which provides centrifugation and counter-current cooling with the fluid to be heated, the distillates rid of their "humidity" (the heavy parts of "residue" entrained being returned to column 14 through the conduit 38) are brought by the conduit 39 inside the condenser 2 cooled against the current by the fluid circuit to be heated in which the condensation takes place. The condensed distillates are then admitted via line 41 into the pressure reducer 3 in which their expansion and subsequent cooling takes place. They heat up in the evaporator 4 which can be an air exchanger exchanging heat with the ambient medium or for example water exchanging heat with waste water. It is at this device, as it is known that the heat is borrowed from the outside environment. The distilled distilled thus warmed at the outlet of the evaporator 4 penetrate by the conduit 43 at the top of the absorption column 5. In this column, the distillates are absorbed by the heavy residues brought by the conduit 44 into the absorber and to which they mix, releasing heat, which is partly exchanged with the fluid to be heated as will be described below in relation to this circuit. The mixing solution leaves the absorber via the conduit 45 from where it is taken up by the pump 6 to be brought back after crossing the heat exchanger 7 in counter current with the hot residues coming from the column 14, before entering in the exchanger 10 then the chamber 20 formed around the combustion chamber 17 before being introduced into the separation column 14 through the conduit 24.

2) Circulation des résidus.2) Circulation of residues.

Les résidus du cycle d'absorption quittant la base de la colonne 14 par le conduit 29 sont amenés par un circuit repéré 46 dans l'échangeur 7 en contre-courant avec la solution à régénérer qu'ils réchauffent. En suite de quoi les résidus passent par le conduit 47 dans l'échangeur de chaleur supplémentaire 8 lequel est refroidi à contre courant par le circuit du fluide à chauffer. A la sortie de l'échangeur 8 les résidus refroidis pénètrent par le conduit 44 en tête de la colonne d'absorption 5 pour s'y mélanger avec les distillats amenés à la colonne par le conduit 43.The residues of the absorption cycle leaving the base of the column 14 via the conduit 29 are brought by a circuit marked 46 in the exchanger 7 in counter-current with the solution to be regenerated which they heat. As a result of which the residues pass through the conduit 47 in the additional heat exchanger 8 which is cooled against the current by the circuit of the fluid to be heated. At the outlet of the exchanger 8, the cooled residues penetrate via the conduit 44 at the head of the absorption column 5 to mix therewith the distillates brought to the column by the conduit 43.

3) Circulation du fluide à chauffer.3) Circulation of the fluid to be heated.

L'entrée froide dû fluide à chauffer qui peut constituer par exemple les retours froids d'un chauffage central s'effectue en 48 à l'extrémité de l'échangeur 11 par lequel sont évacuées les fumées 13 de l'installation. En 49 est figurée l'évacuation des condensats provenant des fumées, la température des retours froids permettant généralement de récupérer au moins une grande partie de la chaleur de condensation des fumées.The cold inlet due to the fluid to be heated which can constitute, for example, the cold returns of a central heating takes place at 48 at the end of the exchanger 11 by which the fumes 13 from the installation are evacuated. In 49 is shown the evacuation of condensates from the fumes, the temperature of the cold returns generally making it possible to recover at least a large part of the heat of condensation of the fumes.

A la sortie de l'échangeur 11 le fluide de chauffage gagne par un conduit,49 l'absorbeur 5, ce qui permet un refroidissement optimal des condensats améliorant les conditions de travail du cycle d'absorption. Après l'absorbeur 5 le fluide de chauffage est amené par un conduit 50 dans l'échangeur de chaleur 8, ce qui dans la position normale de fonctionnement de l'installation jusqu'à présent décrite permet de récupérer une partie de la chaleur des résidus avant leur entrée dans la colonne d'absorption 5. A la sortie de l'échangeur 8, le fluide à.chauffer gagne par un conduit 51 le condenseur 2 dans lequel s'effectue la plus grande partie de l'apport de chaleur réalisé par le circuit d'absorption. A la sortie du condenseur 2 le fluide à chauffer gagne par un conduit 52 le déflegmateur 16 dans lequel s'effectue une dernière opération de chauffage, laquelle permet comme il a été décrit plus haut d'améliorer l'épuration et la séparation en distillat léger et résidu lourd de la solution d'absorption à la sortie de la colonne d'absorption 5.At the outlet of the exchanger 11, the heating fluid gains through a conduit, the absorber 5, which allows optimal cooling of the condensates improving the working conditions of the absorption cycle. After the absorber 5 the heating fluid is brought through a pipe 50 into the heat exchanger 8, which in the normal operating position of the installation hitherto described makes it possible to recover part of the heat from the residues before entering the absorption column 5. At the outlet of the exchanger 8, the fluid to be heated gains via a pipe 51 the condenser 2 in which most of the heat is supplied by the absorption circuit. At the outlet of the condenser 2, the fluid to be heated gains via a conduit 52 the de-phlegmator 16 in which a final heating operation takes place, which allows, as described above, to improve the purification and the separation. in light distillate and heavy residue of the absorption solution at the outlet of the absorption column 5.

Lorsque les conditions de fonctionnement du cycle d'absorption ne sont pas favorables, c'est-à-dire par exemple lorsque la température de la source froide à laquelle la chaleur extérieure est emprunté esttrop basse, on peut arrêter la fonctionnement du cycle d'absorption, c'est-à-dire le fonctionnement du déflegmateur 16, du condenseur 2,du détendeur 3 et de l'évaporateur 4, ainsi que le fonctionnement de l'échangeur 7 qui est court-circuité par un conduit 53 disposé en parallèle sur l'échangeur 7 et commandé par une vanne 54.When the operating conditions of the absorption cycle are not favorable, that is to say for example when the temperature of the cold source from which the external heat is borrowed is too low, the operation of the cycle can be stopped. absorption, that is to say the operation of the de-phlegmator 16, the condenser 2, the regulator 3 and the evaporator 4, as well as the operation of the exchanger 7 which is short-circuited by a conduit 53 arranged in parallel on the exchanger 7 and controlled by a valve 54.

Dans de telles conditions de fonctionnement, on voit que le fluide à chauffer est chauffé essentiellement dans l'échangeur 11 puis dans l'échangeur 8, lequel est chauffé par le circuit de la solution traversant l'échangeur 10, la base de la colonne 14 le conduit 29, la dérivation 53,1'échangeur 8 et retournant à l'échangeur 10 après traversée de d'absorbeur 5 (qui ne fonctionne plus en tant qu'absorbeur) et le conduit de retour 45 via la pompe de circulation 6.Under such operating conditions, it can be seen that the fluid to be heated is heated essentially in the exchanger 11 then in the exchanger 8, which is heated by the circuit of the solution passing through the exchanger 10, the base of the column 14 the duct 29, the bypass 53, exchanger 8 and returning to the exchanger 10 after passing through the absorber 5 (which no longer functions as an absorber) and the return conduit 45 via the circulation pump 6.

De la description qui précède, il apparaît que l'installation conçue selon l'invention et utilisant des appareillages simples et peu nombreux présente une très grande souplesse d'emploi, autorise une grande compacité de construction, et permet le fonctionnement de l'installation avec mise hors circuit ou en circuit selon les conditions les plus favorables du cycle d'absorption formant pompe à chaleur. En outre dans son fonctionnement associé à la pompe à chaleur, l'installation permet d'obtenir des rendements améliorés par rapport aux installations connues, grâce à une meilleure séparation des distillats et résidus produits dans le cycle d'absorption, permettant de meilleurs rendements de ce cycle et parallèlement une meilleure récupération de la chaleur latente - et de condensation des fumées et également latente et de condensation au niveau du cycle d'absorption et notamment des distillats dans la colonne de séparation 14 et dans le déflegmateur 16.From the foregoing description, it appears that the installation designed according to the invention and using few and simple apparatuses has very great flexibility of use, allows great compactness of construction, and allows the operation of the installation with switching off or on according to the most favorable conditions of the absorption cycle forming the heat pump. In addition, in its operation associated with the heat pump, the installation makes it possible to obtain improved yields compared to known installations, thanks to better separation of the distillates and residues produced in the absorption cycle, allowing better yields of this cycle and at the same time better recovery of the latent heat - and of condensation of the fumes and also latent and of condensation at the level of the absorption cycle and in particular of the distillates in the separation column 14 and in the de-phlegmator 16.
