Description

La présente invention concerne une pompe à chaleur du type air-eau ou air-air.The present invention relates to a heat pump of the air-water or air-air type.

Une pompe à chaleur de ce type décrite dans le document U.S. 4 138 859 comprend un châssis qui supporte un évaporateur et un ventilateur, l'évaporateur comprenant un serpentin hélicoidal d'axe général vertical. En fonctionnement, l'évaporateur est parcouru par un fluide caloporteur pour prélever des calories sur l'air ambiant déplacé par le ventilateur. Le serpentin est placé dans le châssis et il est protégé par un habillage doté d'orifices ou de fentes d'entrée d'air.A heat pump of this type described in U.S. 4,138,859 includes a frame which supports an evaporator and a fan, the evaporator comprising a helical coil of generally vertical axis. In operation, the evaporator is traversed by a heat transfer fluid to take calories from the ambient air displaced by the fan. The coil is placed in the chassis and is protected by a covering provided with air intake holes or slots.

Lors de la mise en oeuvre de telles pompes à chaleur, on observe que les facteurs climatiques tels que le vent et le soleil entraînent des conséquences fâcheuses pour la fiabilité et la longévité de la pompe.When using such heat pumps, it is observed that climatic factors such as wind and sun have unfortunate consequences for the reliability and longevity of the pump.

En effet, d'une part, le rayonnement solaire peut frapper directement à certaines heures divers points du serpentin et peut donc causer des échauffements différentiels ou des surchauffes locales risquant d'altérer le fonctionnement du compresseur notamment au démarrage ; d'autre part, les fluctuations de force et d'orientation du vent déterminent des variations du débit d'air extrait par le ventilateur et par suite une charge irrégulière de l'évaporateur.Indeed, on the one hand, the solar radiation can strike directly at certain times various points of the coil and can therefore cause differential heating or local overheating risking altering the operation of the compressor, in particular at start-up; on the other hand, the fluctuations in force and orientation of the wind determine variations in the flow of air extracted by the fan and consequently an irregular charge of the evaporator.

Il est proposé par le document U.S. 4 157 368 de réaliser des moyens d'entrée d'air par des lames verticales ménageant entre elles des passages d'écoulement d'air. Toutefois, ce document se rapporte à une tour de refroidissement, ce qui est un domaine différent de celui des pompes à chaleur et la disposition des lames verticales est choisie afin de favoriser la formation d'un tourbillon dans la tour ; cette disposition n'a pas pour but et, de toute façon, n'a pas pour résultat, de soustraire les passages d'écoulement à l'impact du vent ou du rayonnement solaire et d'amener un débit d'air sans variations de charge.It is proposed by document US 4 157 368 to produce air intake means by vertical blades providing between them air flow passages. However, this document relates to a cooling tower, which is a different area from that of heat pumps and the arrangement of the vertical blades is chosen in order to promote the formation of a vortex in the tower; this provision is not intended to, and in any event, is not intended to shield flow passages from the impact of wind or of solar radiation and bring an air flow without load variations.

L'invention a pour but de remédier aux inconvénients des pompes à chaleur air-eau ou air-air connues en les dotant de moyens d'entrée d'air qui, tout en restant de conception simple et d'emploi commode, sont insensibilisés à l'irrégularité des facteurs climatiques.The invention aims to remedy the drawbacks of air-water or air-air heat pumps known by providing them with air intake means which, while remaining simple in design and convenient to use, are rendered insensitive to the irregularity of climatic factors.

Ce but est atteint au moyen d'une pompe à chaleur air-eau ou air-air du type défini en tête de la description et dans laquelle, selon l'invention, les moyens d'entrée d'air comprennent des lames disposées à intervalles réguliers et ménageant entre elles des canaux d'é- coulement d'air ; et les lames offrent une section transversale comprenant une large branche extérieure et une branche intérieure profilée et sont disposées mutuellement afin, d'une part, de soustraire les canaux à l'impact du vent et l'évaporateur à l'impact du rayonnement solaire et, d'autre part, d'autoriser une entrée tangentielle et régulière de l'air vers l'évaporateur.This object is achieved by means of an air-water or air-air heat pump of the type defined at the head of the description and in which, according to the invention, the air inlet means comprise blades arranged at intervals regular and leaving between them E- channels co ul air ement; and the blades offer a cross section comprising a wide outer branch and a profiled inner branch and are arranged mutually so as, on the one hand, to shield the channels from the impact of the wind and the evaporator from the impact of the solar radiation and , on the other hand, to allow a tangential and regular entry of air to the evaporator.

De la sorte, le serpentin de l'évaporateur reçoit tangentiellement un débit d'air constant et n'est plus soumis à des surchauffes locales.In this way, the evaporator coil receives tangentially a constant air flow and is no longer subject to local overheating.

Plusieurs modes de réalisation de l'ensemble de lames verticales peuvent être envisagés.Several embodiments of the set of vertical blades can be envisaged.

La protection contre le vent et le soleil est obtenue par exemple en juxtaposant les lames de manière que la branche extérieure d'une lame cache en partie la branche intérieure de la lame adjacente.Protection against wind and sun is obtained for example by juxtaposing the blades so that the outer branch of a blade partially hides the inner branch of the adjacent blade.

Le profil des lames peut être en S de manière que la branche extérieure du S d'une lame recouvre en partie la branche intérieure du S de la lame adjacente, ce qui permet d'améliorer l'effet tangentiel recherché pour l'introduction de l'air, tandis que la branche intérieure offre sa convexité au flux d'air pour le régulariser.The profile of the blades can be S-shaped so that the outer branch of the S of a blade partially covers the inner branch of the S of the adjacent blade, which improves the tangential effect sought for the introduction of the air, while the inner branch offers its convexity to the air flow to regulate it.

Chaque lame peut être réalisée en une seule pièce moulée ou extrudée ou, en variante, en deux parties verticales séparées dont l'une comprend la branche extérieure et l'autre la branche intérieure. Les parties de lames extérieures et intérieures forment alors deux ensembles distincts concentriques.Each blade can be produced in a single molded or extruded part or, as a variant, in two separate vertical parts, one of which comprises the outer branch and the other the inner branch. The outer and inner blade parts then form two separate concentric assemblies.

Les lames peuvent être regroupées en plusieurs persiennes verticales.The slats can be grouped into several vertical louvers.

L'une au moins des persiennes est rigide et peut pivoter autour de gonds ou d'axes verticaux solidaires du châssis de l'évaporateur afin de prendre soit la position fermée de fonctionnement normal, soit une position d'ouverture ménageant un passage limité entre deux persiennes adjacentes. Il en résulte que même en cas d'obstruction des canaux de chaque persienne par le givre ou la neige, un écoulement d'air suffisant peut passer entre les persiennes vers le serpentin.At least one of the louvers is rigid and can pivot around hinges or vertical axes integral with the chassis of the evaporator in order to take either the closed position for normal operation, or an open position providing a limited passage between two adjacent shutters. As a result, even if the channels of each louver are obstructed by frost or snow, sufficient air flow can pass between the louvers towards the coil.

De plus, lorsque la pompe à chaleur est du type monobloc à habillage cylindrique d'axe vertical et contient par conséquent, outre l'évaporateur, le compresseur et son bloc de régulation ainsi que le condenseur, il est prévu pour l'une au moins des persiennes une position de pleine ouverture permettant d'accéder facilement à l'intérieur de l'habillage pour réparer ou remplacer le bloc de régulation ou le compresseur.In addition, when the heat pump is of the monobloc type with cylindrical casing of vertical axis and therefore contains, in addition to the evaporator, the compressor and its regulating block as well as the condenser, it is provided for at least one louvers a fully open position allowing easy access to the interior of the cabinet to repair or replace the control unit or the compressor.

The description which follows with reference to the appended drawings will make it possible to understand by way of example how the invention can be put into practice.
  • FIG. 1 represents, in diagrammatic elevation, a unitary air-water heat pump according to the invention.
  • Figure 2 is a sectional view of Figure 1 along the horizontal plane II-II.
  • Figures 3 and 4 are also sectional views through the same plane, showing the louvers with vertical blades respectively in the limited open position fully open position.
  • Figure 5 shows on a larger scale the detail A of Figure 2.

Dans le mode de réalisation illustré sur les figures, l'évaporateur selon l'invention est intégré à une pompe à chaleur monobloc à compression avec les avantages qui seront mis en évidence ci-après mais il pourrait bien entendu être construit séparément en tant qu'élément extérieur d'une pompe à chaleur air-eau ou air-air dont le compresseur, le condenseur et la régulation seraient dès lors regroupés à l'intérieur du bâtiment à chauffer (version dite "split system").In the embodiment illustrated in the figures, the evaporator according to the invention is integrated into a one-piece compression heat pump with the advantages which will be highlighted below, but it could of course be constructed separately as external element of an air-water or air-air heat pump whose compressor, condenser and regulation would therefore be grouped inside the building to be heated (so-called "split system" version).

La pompe à chaleur 10 présente un châssis à socle Il abritant le condenseur et un habillage 12 cylindrique constitué par un ensemble de lames verticales 13, par exemple en aluminium extrudé, réparties régulièrement sur la périphérie d'un évaporateur 14 formé par un serpentin hélicoïdal dont l'axe général vertical est sensiblement le même que celui de l'habillage.The heat pump 10 has a base frame It houses the condenser and a cylindrical casing 12 constituted by a set of vertical blades 13, for example made of extruded aluminum, distributed regularly over the periphery of an evaporator 14 formed by a helical coil of which the general vertical axis is substantially the same as that of the covering.

Un liquide caloporteur mis en circulation dans le serpentin est porté à ébullition par prélèvement de la chaleur de l'air qu'un ventilateur 15 force à passer dans les canaux 16 entre les lames 13 et à lécher le serpentin avant de l'expulser par une ouverture non représentée.A heat transfer liquid circulated in the coil is brought to a boil by drawing heat from the air which a fan 15 forces to pass through the channels 16 between the blades 13 and to lick the coil before expelling it by a opening not shown.

Les lames rectilignes et verticales 13 protègent le serpentin 14 du vent et du rayonnement solaire tous azimuts et elles permettent en outre une introduction tangentielle de l'air vers le serpentin 14 (flèche 25 sur la figure 5). Les lames 13 sont groupées en trois persiennes incurvées 13a, 13b, 13c enveloppant étroitement le serpentin et montées à pivotement sur des gonds ou axes verticaux 17a, 17b, 17c. Les lames de chaque persienne sont fixées à leurs extrémités à un arceau inférieur et à un arceau supérieur respectifs montés pivotants sur l'axe vertical correspondant. Les persiennes peuvent occuper une position fermée de fonctionnement normal (figure 2), une position de semi-ouverture (figure 3) et, pour au moins l'une d'entre elles, une position de pleine ouverture (figure 4).The rectilinear and vertical blades 13 protect the coil 14 from wind and solar radiation in all directions and they also allow a tangential introduction of air to the coil 14 (arrow 25 in Figure 5). The blades 13 are grouped into three curved louvers 13a, 13b, 13c tightly enveloping the coil and pivotally mounted on hinges or vertical axes 17a, 17b, 17c. The slats of each louver are fixed at their ends to a respective lower hoop and upper hoop mounted pi voters on the corresponding vertical axis. The shutters can occupy a closed position for normal operation (Figure 2), a semi-open position (Figure 3) and, for at least one of them, a fully open position (Figure 4).

Dans la position de la figure 3, la persienne laisse dégagée une ouverture 18 entre elle-même et la persienne adjacente pour procurer un cheminement à l'air même en cas d'obstruction des canaux 16 par le givre ou la neige.In the position of Figure 3, the louver leaves an opening 18 open between itself and the adjacent louver to provide a path to the air even if the channels 16 are obstructed by frost or snow.

Dans la position de la figure 4, la persienne 13a permet l'intervention par l'ouverture 19 sur le compartiment 20 contenant le compresseur 21, le bloc de régulation 22, .....par exemple le démontage et le retrait de ces composants selon la flèche F.In the position of FIG. 4, the louver 13a allows intervention by the opening 19 on the compartment 20 containing the compressor 21, the regulation block 22, ..... for example the disassembly and removal of these components according to arrow F.

La figure 5 montre la forme et l'agencement des lames 13 profilées de protection d'une des persiennes 13b. Le profil des lames 13 est sensiblement en forme de S aplati tel que la branche extérieure 23 de chaque S recouvre la branche intérieure 24 du S de la lame adjacente ; l'écoulement de l'air s'effectue ainsi dans les canaux 16 ménagés entre la branche 23 d'une lame et la branche 24 de la lame adjacente selon la flèche 25 et l'on constate que le flux d'air parvient tangentiellement et régulièrement au serpentin hélicoïdal 14 après glissement sur la convexité 26 de la branche 24, quelles que soient la force et la direction du vent. De plus, la chaleur due au rayonnement solaire est absorbée par les lames 13 et elle est restituée indirectement au serpentin 14. La largeur de chaque lame est d'environ 10 cm.FIG. 5 shows the shape and arrangement of the profiled blades 13 for protecting one of the louvers 13b. The profile of the blades 13 is substantially in the form of a flattened S such that the outer branch 23 of each S covers the inner branch 24 of the S of the adjacent blade; the air flow thus takes place in the channels 16 formed between the branch 23 of a blade and the branch 24 of the adjacent blade according to arrow 25 and it can be seen that the air flow reaches tangentially and regularly with the helical coil 14 after sliding on the convexity 26 of the branch 24, whatever the force and the direction of the wind. In addition, the heat due to solar radiation is absorbed by the blades 13 and it is returned indirectly to the coil 14. The width of each blade is approximately 10 cm.

Dans une variante non représentée, chaque lame 13 peut être montée pivotante sur des gonds verticaux tandis que la rotation autour de l'axe général de l'habillage 12 d'une couronne reliée aux lames permet de modifier l'orientation des lames.In a variant not shown, each blade 13 can be pivotally mounted on vertical hinges while the rotation about the general axis of the covering 12 of a crown connected to the blades makes it possible to modify the orientation of the blades.

Dans une autre variante non représentée, les lames 13 sont chacune en deux parties séparées, l'une formant la branche 23 et l'autre formant la branche 24. Les branches intérieures et extérieures constituent alors deux couronnes concentriques.In another variant not shown, the blades 13 are each in two separate parts, one forming the branch 23 and the other forming the branch 24. The inner and outer branches then constitute two concentric rings.
