Abstract
Description
L'invention a pour objet une installation de deshumidification à circuits multiples d'évaporation-condensation, et à pompe à chaleur. The subject of the invention is a dehumidification installation with multiple evaporation-condensation circuits and with a heat pump.
On connait déjà des installations de deshunidification ou sé
chage comportant une pompe à chaZeur, c'estadire, un compresseur de fluide frigorigène, un échangeur jouant Ze rôZe d'évaporateur, un échan
geur jouant Ze rôZe de condenseur et un organe de détente.We already know deshunidification or se
chage comprising a chaZeur pump, that is, a refrigerant compressor, an exchanger playing Ze rôZe evaporator, an echan
geur playing Ze rôZe of condenser and an expansion device.
Lorsqu'une teZZe instaZZation est prévue pour la deshumidifi
cation d'un milieux gazeux par exemple pour une piscine couverte, Ze
coéfficient de performance - rapport de la puissance calorifique produi
te à la puissance absorbée - est faible, en raison de l'importance de la puissance absorbée eZZe-même due aux irréversibiZités des échanges thermiques.When a teZZe instaZZation is planned for dehumidifi
cation of a gaseous medium for example for an indoor swimming pool, Ze
coefficient of performance - ratio of the calorific power produced
te to the absorbed power - is low, due to the importance of the absorbed power eZZe itself due to the irreversibility of the heat exchanges.
On a déjà proposé, pour pallier l'inconvénient lié aux fortes
irréversibilités des échanges thermiques, de fractionner l'installation,
c'est-à-dire de constituer ceZle-ci suivant plusieurs étages de pompe à
chaleur. On a égaZement proposé de rempZacer un étage de pompe à chaleur par un récupérateur statique. De telles installations ne sont pas toutefois entièrement satisfaisantes, car la récupération de chaZeur étagée
séffectue toujours dans des appareils différents, ce qui conduit, d'une part, à des fuites d'air entre Zes deux flux gazeux et à des pertes de
charge importantes sur Zes circuits aérauliques, et, d'autre part, à de graves problèmes pour l'évacuation des condensats.Par aiZZeurs, Zes dispositifs de réguZation de récupérateur statique sont toujours complexes.We have already proposed, to overcome the drawback associated with strong
irreversibility of heat exchanges, of splitting up the installation,
that is to say to constitute this following several stages of pump to
heat. It has also been proposed to replace a heat pump stage with a static recuperator. However, such installations are not entirely satisfactory, since the recovery of storied heat
is always carried out in different devices, which leads, on the one hand, to air leaks between Zes two gas streams and to losses of
significant load on the aeraulic circuits, and, on the other hand, to serious problems for the evacuation of condensates.
Dans Zes installations de deshumidification par systeme de pompe à cha
leur, des problèmes importants de surchauffe de Z'air envoyé dans Ze Zo
caZ existent, des dispositifs complexes de régulation ont été proposés mais ne donnent pas satisfaction.In dehumidification systems using a heat pump system
their, significant problems of Z'air overheating sent in Ze Zo
caZ exist, complex regulation devices have been proposed but are not satisfactory.
C'est , d'une manière générale, un but de Z'invention de four
nir une installation qui ne présente pas Zes inconvénients, rappelés cidessus, des instaZZations connues.It is, generally speaking, an object of the oven invention
nir an installation which does not have the disadvantages, recalled above, of known instaZZations.
C'est, en particulier, un but de Z'invention de fournir une
installation dont la récupération de chaZeur sur la source froide s'effectue dans un évaporateur monobloc muitizone. It is, in particular, an object of the invention to provide a
installation whose recovery of heat from the cold source is carried out in a mono-block evaporator muitizone.
C'est aussi un but de Z'invention de fournir une telle instaZ-
Zation qui ne fasse appel qu'à un condenseur monobloc muitizone pour Ze
chauffage de la source chaude.It is also an object of the invention to provide such an installation.
Zation which uses only a mono-block condenser muitizone for Ze
heating the hot spring.
C'est encore un but de Z'invention de fournir une installation dans ZaqueZZe la circulation de fluide frigorigène entre Ze condenseur multizone et l'évaporateur multizone s'effectue partiellement ou totalement par thermosiphon avex changement d'état physique du fluide. It is also an aim of the invention to provide an installation in ZaqueZZe the circulation of refrigerant between the multizone condenser and the multizone evaporator takes place partially or totally by thermosyphon with change of physical state of the fluid.
Une installation de deshumidification selon l'invention, comprenant des échangeurs multizones, et caractérisée en ce que Zes zones des échangeurs de chaleur sont diposées,respectivement, en série et adjacentes Zes unes aux autres sur Zes flux gazeux baZayant respectivement Zes dites zones des échangeurs. Chaque échangeur est empZi d'un fZuide frigorigène . A dehumidification installation according to the invention, comprising multizone exchangers, and characterized in that Zes zones of the heat exchangers are arranged, respectively, in series and adjacent Zes to each other on Zes gaseous flows baZay respectively Zes said zones of exchangers. Each exchanger is equipped with a refrigerant.
Selon une autre caractéristique de l'invention, un premier miZieu gazeux balaie successivement Zes zones de l'échangeur jouant Ze rôZe d'évaporateurs de la première zone, de la seconde, de la troisième, etc... de la nième zone, tandis qu'un second miZieu gazeux baZaie successivement Zes zones de Z'échangeur jouant Ze rôle de condenseurs de la n lème zone, de la n-2ème zone, etc...de la troisième zone, de la seconde zone, de la première zone et de la nième zone, la circulation du fluide frigorigène entre Ze condenseur et l'évaporateur des zones 1 à n-1 s'effectuant par circulation naturelle, aZors de la circuZation de fluide de la nième zone s'effectue par l'intermédiaire d'un compresseur. According to another characteristic of the invention, a first gaseous miZieu scans successively Zes of the exchanger playing Ze rôZe of evaporators of the first zone, of the second, of the third, etc ... of the nth zone, while that a second gaseous medium successively sweeps the zones of the exchanger playing the role of condensers of the nth zone, of the n-2nd zone, etc. of the third zone, of the second zone, of the first zone and from the nth zone, the circulation of the refrigerant between the condenser and the evaporator of zones 1 to n-1 takes place by natural circulation, during the circulation of fluid from the nth zone takes place via 'a compressor.
L'invention sera bien comprise par la description qui suit, faite à titre d'exemple et en référence aux dessins annexés dans ZequeZ : - la figure 1 est un schéma d'une installation seZon Z'invention - la figure 2 est un schéma analogue à celui de la figure 1 mais pour
une variante permettant des entrées et sorties d'air intermédiaires - Zes figures 3 et 4 représentent un éZément constitutif de l'installa-
tion - Zes figures 5 et 6 en sont une variante.The invention will be better understood from the following description, given by way of example and with reference to the drawings appended in ZequeZ: - Figure 1 is a diagram of an installation according to the invention - Figure 2 is a similar diagram to that of figure 1 but for
a variant allowing intermediate air inlets and outlets - Zes Figures 3 and 4 represent a component of the installation
tion - Zes Figures 5 and 6 are a variant.
Une installation de deshumidification selon Z'invention lOi figure 1, comprend une entrée d'air humide a. L'air humide est refroidi par Zes évaporateurs statiques 15, au cours de ce refroidissement, iZ se forme une première condensation de Z'eau contenue dans L'air humide a. A dehumidification installation according to the invention 10 FIG. 1, comprises a humid air inlet a. The humid air is cooled by Zes static evaporators 15, during this cooling, iZ forms a first condensation of the water contained in the humid air a.
L'air est ensuite admis sur un évaporateur 16 formant partie constitutive d'une trompe à chaleur. Sur cet échangeur, Z'air humide est refroidi à nouveau, de façon plus intense, ce qui permet de condenser la plus grande partie de l'eau contenue dans l'air. The air is then admitted to an evaporator 16 forming a constituent part of a heat pump. On this exchanger, the humid air is cooled again, more intensively, which makes it possible to condense most of the water contained in the air.
Les condensats sont recueillis dans un bac d et sont évacués par l'intermédiaire de la tuyauterie c. The condensates are collected in a tank d and are evacuated via the piping c.
Après deshumidification, Z'air froid est admis en partie supérieure de l'appareil où iZ recueiZZe dans Zes condenseurs statiques il la chaleur qui a été prélevée par Zes évaporateurs statiques 11. After dehumidification, cold air is admitted into the upper part of the apparatus where iZ collects in the static condensers the heat which has been taken up by the static evaporators 11.
L'air réchauffé est ensuite admis sur Ze condenseur 12 du circuit de pompe à chaleur, Z'air chaud et sec est ensuite soufflé dans Ze
ZocaZ, par l'intermédiaire du ventiZateur 13. The heated air is then admitted to the condenser 12 of the heat pump circuit, the hot and dry air is then blown into Ze
ZocaZ, via the ventilator 13.
Le circuit de la pompe à chaleur comporte un deuxième condenseur 26 permettant d'évacuer sur un autre circuit extérieur entrée sortie la chaZeur excédentaire qui n'est pas utiZe pour le ZocaZ à traiter. Pour une piscine couverte, la pompe de circulation 27 commandée par la régulation de température du ZocaZ permettra la mise en route de ce deuxième condenseur. The heat pump circuit includes a second condenser 26 allowing the excess heat which is not used for the ZocaZ to be treated to be removed to another external input / output circuit. For an indoor swimming pool, the circulation pump 27 controlled by the ZocaZ temperature regulation will allow this second condenser to be started.
Le condenseur 26 pourra être égaZement installé après Ze condenseur 12 ( sur la figure 1, iZ est placé avant ). The condenser 26 can also be installed after the condenser 12 (in FIG. 1, iZ is placed before).
Dans une variante, Ze fluide frigorigène contenu dans Ze circuit de la pompe à chaZeur pourra être un mélange de fZuide non azéotropique, ce qui permettra d'améliorer Zes performances en utiZisant des échangeurs 12 et 16 à contre courant et à température variable de condensation et d'évaporation. In a variant, the refrigerant contained in the circuit of the heat pump can be a mixture of non-azeotropic fuel, which will make it possible to improve their performance by using exchangers 12 and 16 against the current and at variable temperature of condensation and evaporation.
Dans une autre variante, la pompe à chaZeur peut etre équipée de deux ou trois circuits indépendants, Zes échangeurs 12 et 16 sont alors séparés en deux ou trois parties adjacentes Zes unes aux autres permettant ainsi une récupération de chaZeur étagée, d'une manière analogue à celle assurée par les circuits multiples du récupérateur comportant Zes échangeurs 11 et 25. In another variant, the chaZeur pump can be equipped with two or three independent circuits, the exchangers 12 and 16 are then separated into two or three adjacent parts Zes to each other thus allowing recovery of storied chaZer, in an analogous manner to that provided by the multiple circuits of the recuperator comprising Zes exchangers 11 and 25.
L'installation de deshumidification selon Z'invention comporte un dispositif 11 de transfert de chaleur et un dispositif 15 de captation de chaleur, figures 3 et 4. Le condenseur il estc3nstitué d'une série de condenseurs 111 , 112 , 113 , etc..., adjacents les uns aux autres. Chaque éZément se compose d'un ensemble de tubes horizontaux superposés 351v 352 353J etc... reliés entre eux par des coudes 361, 362,363, etc... de manière à former un serpentin de condensation. Les tubes 35, en cuivre,aZumi- nium,ou autre, sont Zisses ou poreux intérieurement, et extérieurement garnis d'aiglettes verticales 39 généralement en aluminium.L'évaporateur 15 est constitué d'une série d'évaporateurs 151,152,153, etc... adjacents Zes uns aux autres. Chaque élément se compose d'un ensemble de tubes horizontaux superposés 3?î, 3?2, 373, etc... reliés entre eux par des coudes 381, 382,383, etc... de manière à former un serpentin d'évaporation. The dehumidification installation according to the invention comprises a device 11 for transferring heat and a device 15 for collecting heat, FIGS. 3 and 4. The condenser is composed of a series of condensers 111, 112, 113, etc. ., adjacent to each other. Each element consists of a set of superimposed horizontal tubes 351v 352 353J etc ... connected together by elbows 361, 362,363, etc ... so as to form a condensing coil. The tubes 35, made of copper, aluminum, or other, are Zisses or porous internally, and externally lined with vertical tabs 39 generally made of aluminum. The evaporator 15 consists of a series of evaporators 151, 152, 153, etc. adjacent to each other. Each element consists of a set of superimposed horizontal tubes 3?, 3? 2, 373, etc ... connected together by elbows 381, 382,383, etc ... so as to form a coil of evaporation.
Les tubes 37, en cuivre, aluminium, ou autre, sont Zisses ou poreux intérieurement, et extérieurement garnis d'ailettes verticales 41, ce qui facilite l'écoulement des condensats. The tubes 37, made of copper, aluminum, or the like, are Zisses or porous internally, and externally furnished with vertical fins 41, which facilitates the flow of condensate.
Les éléments respectifs de condenseurs 21 et d'évaporateurs 15 sont reliés entre eux par des tuyauteries 17 et 18 afin de former des circuits fermés tel que représenté figure 3. Chaque circuit est équipé d'un orifice de tirage au vide et de remplissage 34 constitué d'une valve ou plus simplement d'un tube pincé soudé apres remplissage. The respective elements of condensers 21 and evaporators 15 are connected together by pipes 17 and 18 in order to form closed circuits as shown in FIG. 3. Each circuit is equipped with a vacuum and filling orifice 34 constituted a valve or more simply a pinched tube welded after filling.
Le Ziquide frigorigène descend dans l'évaporateur par la tuyautreie 18 et un siphon 33. La chialeur puisée à Z'air humide fait entrer le liquide en ébullition à l'intérieur des tubes 37, Zes vapeurs ainsi formées montent dans Ze condenseur par Ze tuyauterie 17; Zes vapeurs se condensent dans Zes tubes 35 cédant ainsi de la chaleur à Z'air neuf, le liquide formé retourne gravitairement dans Z'évaporateur par la tuyauterie 18. The refrigerant Ziquide descends into the evaporator through the pipe 18 and a siphon 33. The chialeur drawn from the humid air brings the boiling liquid inside the tubes 37, the vapors thus formed rise in Ze condenser through Ze piping 17; The vapors condense in the tubes 35 thus yielding heat to the fresh air, the liquid formed returns gravitatively to the evaporator through the pipe 18.
Tous les éléments du condenseur 11, hormis Zes coudes 36, sont insérés dans une gaine 40 commune destinée à canaliser l'air; le (ou les) condenseur(s) 12 du (ou des) circuit(s) de pompe(s) de chaZeur peuvent avantageusement etre insérés dans la même gaine 40 formant ainsi une seule batterie ailettée. De même, tous Zes éléments de l'évaporateur 15, hormis les coudes 38, sont insérés dans une gaine 42 destinée à canaliser Z'air; Ze (ou ZesJ évaporateur(s) 16 du ( ou des) circuit(s) de pompe(s) à chaleur peuvent également etre insérés dans la même gaine 42 formant ainsi une seule batterie aiZettée. All the elements of the condenser 11, apart from the elbows 36, are inserted into a common sheath 40 intended to channel the air; the condenser (s) 12 of the chaZer pump circuit (s) can advantageously be inserted into the same sheath 40 thus forming a single finned battery. Likewise, all the elements of the evaporator 15, except the elbows 38, are inserted into a sheath 42 intended to channel the air; Ze (or ZesJ evaporator (s) 16 of the heat pump circuit (s) can also be inserted in the same sheath 42 thus forming a single coil aiZettée.
La disposition selon Z'invention permet ainsi une séparation phy sique complète par la plaque 25 entre Zes deux flux gazeux. The arrangement according to the invention thus allows complete physical separation by the plate 25 between Zes two gas streams.
Dans une autrevariante,le dispositif d'échange thermique formé par Zes échangeurs 21 et 15 est remplacé par Ze dispositif d'échange thermique à caloducs des figures 5 et 6. In another variant, the heat exchange device formed by the exchangers 21 and 15 is replaced by the heat exchange device with heat pipes of FIGS. 5 and 6.
Dans ce dispositif l'échangeur est constitué d'une série de tubes verticaux 50 reliés en partie haute est en partie basse par des coudes 51. In this device, the exchanger consists of a series of vertical tubes 50 connected in the upper part and in the lower part by elbows 51.
Chaque nappe de tubes comporte un orifice de remplissage 52. Une cloison 53 permet de séparer Zes deux flux d'air, air humide et chaud en partie basse, air froid et sec en partie haute.Each layer of tubes has a filling orifice 52. A partition 53 makes it possible to separate Zes from two air flows, humid and hot air at the bottom, cold and dry air at the top.
Le transfert de chaZeur s'effectue dans chaque tube par Z'évaporation du liquide frigorigène 54 dans Ze partie basse, Zes vapeurs remontent dans Ze tube en partie haute où elles se condensent sur les parois internes du tube réchauffant ainsi l'air du circuit supérieur. Le Ziquide retourne par gravité dans la partie basse de Z'échangeur pour former un nouveau cycle. The transfer of heat takes place in each tube by the evaporation of the refrigerant 54 in the lower part, the vapors rise in the upper tube where they condense on the internal walls of the tube thus heating the air in the upper circuit. . The Ziquide returns by gravity to the lower part of the exchanger to form a new cycle.
L'invention n'est pas limitée bien sûr à son application pour la deshumidification des piscines ni pour Ze séchage de diverses denrées. The invention is of course not limited to its application for dehumidifying swimming pools or for drying various foods.
L'invention est applicable également à la récupération de la cha Zeur de fluides gazeux au même titre que Zes récupérateurs de chaZeur traditionnels mais d'une façon plus intéressante. The invention is also applicable to the recovery of cha Zeur from gaseous fluids in the same way as Zes recuperators of traditional chaZeur but in a more advantageous manner.
L'instaZZation peut etre utiZisée également pour Ze refroidissement de Z'air conditionné Zorsque les pompes à chaZeur sont du type à cycle réversible. The installation can also be used for cooling the air conditioning when the heat pumps are of the reversible cycle type.
