Description

L'invention concerne un dispositif destiné à maintenir, dans un volume déterminé, une pièce d'habitation par exemple, la température ambiante relativement constante.The invention relates to a device intended to maintain, in a determined volume, a living room for example, the ambient temperature relatively constant.

Elle concerne plus précisément un climatiseur capable d'accomplir au moins deux fonctions, celle de réchauffer l'air lorsque la température ambiante a tendance à s'abaisser, et celle de le refroidir lorsque cette température a tendance à s'élever.It relates more precisely to an air conditioner capable of performing at least two functions, that of heating the air when the ambient temperature tends to drop, and that of cooling it when this temperature tends to rise.

On connaît la climatisation dite par évaporation à l'aide d'appareil essentiellement constitué d'un filtre imbibé d'eau, filtre traversé par un courant d'air produit par un motoventilateur qui aspire, à travers le filtre, l'air chaud extérieur à l'arrière de l'appareil, et refoule à l'avant de l'appareil l'air rafraîchi chargé d'humidité. Ce type de climatiseur présente par rapport à la climatisation obtenue par recyclage de l'air sur des éléments froids, l'avantage d'éviter le risque pour l'utilisateur de respirer à la longue un air confiné et desséché. Les climatiseurs par évaporation sont simples, facilement transportables. Malheureusement, dans l'état actuel de la technique, ils ne marchent que dans un sens, à savoir le refroidissement.Known air conditioning said by evaporation using a device essentially consisting of a filter soaked in water, filter crossed by a current of air produced by a fan which draws, through the filter, the hot air outside at the back of the device, and expels the cooled air charged with humidity at the front of the device. This type of air conditioner has, compared to air conditioning obtained by recycling air on cold elements, the advantage of avoiding the risk for the user to breathe confined and dried air over time. Evaporative air conditioners are simple, easily transportable. Unfortunately, in the current state of the art, they only work in one direction, namely cooling.

Si la température a tendance à baisser, on doit donc avoir recours à un autre type d'appareil. Il s'agit alors le plus souvent de dispositifs aspirant l'air froid, ici encore à l'aide d'un motoventilateur, pour le mettre en contact avec des éléments chauffants avant de le refouler, ainsi réchauffé, à l'avant de l'appareil.If the temperature tends to drop, you have to use another type of device. Most often these are devices which draw in cold air, again using a fan, to bring it into contact with heating elements before discharging it, thus heated, in front of the 'apparatus.

Les éléments chauffants peuvent être des résistances électriques blindées ou des éléments chauffants en céramique semi-conducteurs à résistance à coefficient positif.The heating elements may be shielded electrical resistors or semiconductor ceramic resistance resistors with a positive coefficient.

Ces plaquettes communément appelées PTC présentent l'avantage d'une part, d'avoir une puissance de chauffe modulée par le débit d'air qui les traverse, d'autre part d'apporter toute sécurité quant au fonctionnement de l'appareil car, par principe, leur température maximale est autorégulée à une valeur déterminée par le point de Curie du matériau les constituant.These plates commonly called PTC have the advantage on the one hand, of having a heating power modulated by the air flow which passes through them, on the other hand of bringing all security as for the operation of the device because, in principle, their maximum temperature is self-regulated to a value determined by the Curie point of the material constituting them.

Malheureusement, pour obtenir les deux résultats: réchauffement de l'air d'une part, refroidissement de l'air d'autre part, on doit faire appel à deux appareils distincts qui l'un et l'autre nécessite la mise en oeuvre de moyens de même nature, tels qu'un motoventilateur, un filtre, une pompe...Unfortunately, to obtain the two results: warming of the air on the one hand, cooling of the air on the other hand, we must use two separate devices which both require the implementation of means of the same type, such as a fan, a filter, a pump ...

Le groupement dans un appareil unique capable d'accomplir ces deux fonctions s'est toujours heurté aux difficultés liées à l'humidité véhiculée par les climatiseurs dits à évaporation, humidité qui risque à tout moment d'être incompatible, voir rendre dangereux le fonctionnement des éléments chauffants.The grouping in a single device capable of performing these two functions has always encountered the difficulties linked to the humidity conveyed by the so-called evaporation air conditioners, humidity which risks at all times to be incompatible, see making the functioning of the heating elements.

La présente invention a pour but de résoudre ce problème et concerne un dispositif dont l'architecture des moyens permet précisément d'éviter ce risque.The present invention aims to solve this problem and relates to a device whose architecture means precisely avoids this risk.

Elle concerne plus précisément un dispositif destiné à maintenir une température relativement constante comportant un carter (10) avec un réservoir (3) de liquide (33), une pompe (2), un filtre (1) et un motoventilateur (4), constituant un circuit principal (A) de circulation d'air de l'arrière (AR) du dispositif vers l'avant (AV) de celui-ci selon la flèche (F); caractérisé en ce qu'il comporte en outre un second circuit dit circuit auxiliaire (B) séparé du circuit principal (A) au moyen d'une pièce (6) portant une pluralité de conduits (n, n₁, n₂...nn) qui traversent le filtre (1) et sont destinés à véhiculer également, en coopération avec le motoventilateur (4), l'air depuis l'arrière (AR) vers l'avant (AV) du dispositif selon la dite flèche (F).It relates more precisely to a device intended to maintain a relatively constant temperature comprising a casing (10) with a reservoir (3) of liquid (33), a pump (2), a filter (1) and a fan motor (4), constituting a main circuit (A) for air circulation from the rear (AR) of the device towards the front (AV) thereof according to the arrow (F); characterized in that it further comprises a second circuit called the auxiliary circuit (B) separated from the main circuit (A) by means of a part (6) carrying a plurality of conduits (n, n₁, n₂ ... n n ) which pass through the filter (1) and are intended to also convey, in cooperation with the fan motor (4), the air from the rear (AR) towards the front (AV) of the device according to said arrow (F) .

L'invention sera mieux comprise à l'aide de la description qui va suivre et des figures jointes parmi lesquelles:

  • - la figure 1 est une vue en coupe d'un dispositif conforme à l'invention;
  • - la figure 2 est une vue arrière du dispositif de la figure 1;
  • - la figure 3 est une représentation illustrant schématiquement une pièce du dispositif selon l'invention;
  • - la figure 4 est une section selon (SS) de la figure 3.
The invention will be better understood with the aid of the description which follows and of the appended figures among which:
  • - Figure 1 is a sectional view of a device according to the invention;
  • - Figure 2 is a rear view of the device of Figure 1;
  • - Figure 3 is a representation schematically illustrating a part of the device according to the invention;
  • - Figure 4 is a section along (SS) of Figure 3.

Pour plus de clarté, les mêmes éléments portent les mêmes références dans toutes les figures.For the sake of clarity, the same elements are given the same references in all the figures.

Comme le montre la figure 1, un dispositif conforme à l'invention est constitué d'un carter (10) dans lequel est placé un motoventilateur (4) chargé de créer un courant d'air, selon la flèche (F), depuis l'arrière (AR) jusqu'à l'avant (AV) du dispositif.As shown in Figure 1, a device according to the invention consists of a casing (10) in which is placed a fan (4) responsible for creating a current of air, according to the arrow (F), from the 'rear (AR) to the front (AV) of the device.

Selon une caractéristique importante de l'invention, l'air emprunte deux circuits, l'un dit principal (A) et l'autre dit secondaire (B). Ces deux circuits sont séparés l'un de l'autre au moyen d'une pièce (6) comportant une pluralité de conduits (n₁, n₂...nn).According to an important characteristic of the invention, the air borrows two circuits, one said to be main (A) and the other said to be secondary (B). These two circuits are separated from each other by means of a part (6) comprising a plurality of conduits (n₁, n₂ ... n n ).

Selon une première fonction du dispositif conforme à l'invention, l'air circulant à travers le circuit principal (A) suit la flèche (F₁) en traversant un filtre (1) imbibé d'eau. En effet, une pompe (2) aspire l'eau (33) contenue dans un élément du carter (10) formant un réservoir d'eau (3), pour le refouler, via une canalisation (22), dans un déversoir (23) d'où elle coule dans le filtre (1). Ce circuit principal (A) fonctionne alors en climatiseur par évaporation. L'air chaud ambiant se refroidit au niveau du filtre (1) et s'évacue vers l'avant sous forme d'un flux d'air dit principal (F₁) refroidi, humidifié. Il s'agit là d'un fonctionnement du dispositif dit "en mode froid".According to a first function of the device according to the invention, the air flowing through the main circuit (A) follows the arrow (F₁) by passing through a filter (1) soaked in water. Indeed, a pump (2) sucks the water (33) contained in an element of the casing (10) forming a water tank (3), to discharge it, via a pipe (22), into a weir (23 ) from where it flows into the filter (1). This main circuit (A) then operates as an evaporative air conditioner. The ambient hot air cools at the level of the filter (1) and is evacuated towards the front in the form of a flow of so-called main air (F₁) cooled, humidified. This is an operation of the device known as "in cooling mode".

Le circuit auxiliaire (B) selon l'invention, comme cela est dit ci-dessus, met en oeuvre une pièce (6) comportant une pluralité de conduits (n₁, n₂...nn) traversant le filtre (1). L'air ambiant est aspiré de l'arrière (AR) du dispositif vers l'avant (AV), selon la flèche (F), à travers cette pluralité de conduits (n, n₁...nn). L'extrémité avant de ces derniers, comme le montre la figure 4, comporte chacune au moins un élément chauffant (5).The auxiliary circuit (B) according to the invention, as said above, implements a part (6) comprising a plurality of conduits (n₁, n₂ ... n n ) passing through the filter (1). Ambient air is drawn from the rear (AR) of the device towards the front (AV), along the arrow (F), through this plurality of conduits (n, n₁ ... n n ). The front end of these, as shown in Figure 4, each has at least one heating element (5).

L'air venant de l'arrière (AR) transite à travers la pluralité de conduits (n₁, n₂...nn) de la pièce (6), et à travers les éléments (5). Il se constitue ainsi un flux d'air (F₂) à l'avant du dispositif. Dans ce mode de fonctionnement, ce flux (F₂) est dit secondaire.The air coming from the rear (AR) passes through the plurality of conduits (n₁, n₂ ... n n ) of the room (6), and through the elements (5). An air flow (F₂) is thus formed at the front of the device. In this operating mode, this flow (F₂) is said to be secondary.

Des ailettes (50), qui peuvent être directement moulées dans la pièce (6) sont adaptées pour créer une perte de charge compatible avec celle du filtre (1). Dans ces conditions, le débit d'air transitant dans le circuit principal (A) et le débit d'air traversant les conduits (n, n₁...nn) se trouvent équilibrés. Il en résulte que le débit d'air du circuit auxiliaire (B) ne perturbe pas le fonctionnement du circuit (A) en mode froid.Fins (50), which can be directly molded in the part (6) are adapted to create a pressure drop compatible with that of the filter (1). Under these conditions, the air flow passing through the main circuit (A) and the air flow passing through the conduits (n, n₁ ... n n ) are balanced. It follows that the air flow from the auxiliary circuit (B) does not disturb the operation of the circuit (A) in cooling mode.

Si la pompe (2) n'est pas mise en marche et si le filtre n'est pas imbibé, on obtient une simple ventilation de l'air.If the pump (2) is not started and the filter is not soaked, a simple ventilation of the air is obtained.

Selon une autre fonction réalisée au moyen du dispositif conforme à l'invention et correspondant à un mode dit mode de fonctionnement "chaud", les plaquettes (5) sont mises sous tension et réchauffent donc l'air qui les traverse. Un flux d'air chaud principal (F₂) est donc distribué à l'avant du dispositif. Les ailettes (50) jouent ici encore un rôle d'équilibrage qui assure une puissance de chauffe suffisante en mode "chaud", en particulier lorsque l'on utilise comme éléments chauffants (5) des plaquettes PTC dont la puissance de chauffe augmente avec le débit d'air les traversant.According to another function performed by means of the device according to the invention and corresponding to a mode known as "hot" operating mode, the plates (5) are energized and therefore heat the air passing through them. A main hot air flow (F₂) is therefore distributed to the front of the device. The fins (50) here again play a balancing role which ensures sufficient heating power in "hot" mode, in particular when using as heating elements (5) PTC plates whose heating power increases with the air flow through them.

Dans ce mode "chaud" de fonctionnement, le filtre (1) n'est pas imbibé d'eau. Parallèlement, un flux d'air (F₁) se mêle au flux d'air (F₂). Si la pompe (2) est arrêtée, ce flux (F₁) n'est pas humidifié.In this "hot" operating mode, the filter (1) is not soaked of water. At the same time, an air flow (F₁) mixes with the air flow (F₂). If the pump (2) is stopped, this flow (F₁) is not humidified.

Selon une troisième fonction réalisée au moyen d'un dispositif conforme à l'invention et correspondant à un mode de fonctionnement dit mode "mixte", le filtre (1) est alimenté en eau et les éléments chauffants (5) fonctionnent. On obtient ainsi à l'avant un flux (F₁+F₂) d'air chaud humidifié.According to a third function performed by means of a device according to the invention and corresponding to an operating mode called "mixed" mode, the filter (1) is supplied with water and the heating elements (5) operate. A flow (F₁ + F₂) of humidified hot air is thus obtained at the front.

On peut donc ainsi, avec un dispositif selon l'invention, équipé dans un même carter (10) d'une pompe (2), d'un réservoir d'eau (3), d'un filtre (1), d'un motoventilateur (4) et d'élément chauffant (5), grâce à la séparation du circuit principal (A) et du circuit secondaire (B), faire fonctionner le dispositif à l'aide d'une programmation appropriée, selon trois modes:

  • a) mode "froid" :
    motoventilateur (4) plus pompe (2) conduisant à l'obtention d'air froid;
  • b) mode "chaud" :
    motoventilateur (4) plus élément chauffant (5) conduisant à l'obtention d'air chaud;
  • c) mode "mixte" :
    motoventilateur (4) plus pompe (2) plus élément chauffant (5) conduisant à l'obtention d'un air chaud humidifié.
It is therefore thus possible, with a device according to the invention, equipped in the same casing (10) with a pump (2), with a water tank (3), with a filter (1), with a fan motor (4) and a heating element (5), thanks to the separation of the main circuit (A) and the secondary circuit (B), operate the device using appropriate programming, according to three modes:
  • a) "cold" mode:
    fan motor (4) plus pump (2) leading to the production of cold air;
  • b) "hot" mode:
    fan motor (4) plus heating element (5) leading to the production of hot air;
  • c) "mixed" mode:
    motor fan (4) plus pump (2) plus heating element (5) leading to the production of humidified hot air.

Le fonctionnement en mode ventilé simple est également réalisable.Operation in simple ventilated mode is also possible.

Ces trois, voire quatre, modes de fonctionnement sont possibles grâce à la nouvelle disposition des différents moyens les uns par rapport aux autres, et notamment grâce à la séparation en deux circuits distincts de l'arrivée de l'air à traiter au moyen de la pièce (6).These three, even four, modes of operation are possible thanks to the new arrangement of the different means with respect to each other, and in particular thanks to the separation into two separate circuits of the arrival of the air to be treated by means of the piece (6).

Grâce à ces conduits (n, n₁...nn) l'air est canalisé et isolé du milieu humide que constitue le filtre (1). Ainsi les éléments chauffants (5) se trouvent à l'abri de l'humidité. Ces éléments chauffants peuvent être des éléments semi-­conducteurs à résistance à coefficient positif comme cela a été décrit précédemment, mais il peut s'agir également de résistances chauffantes blindées par exemple.Thanks to these conduits (n, n₁ ... n n ) the air is channeled and isolated from the humid environment formed by the filter (1). Thus the heating elements (5) are protected from moisture. These heating elements can be semiconductor elements with a positive coefficient resistance as described above, but they can also be shielded heating resistors for example.

Dans une variante de réalisation et comme le montrent les figures 2 et 3, la pièce (6) comporte cinq conduits (n, n₁, n₂, n₃, nn) maintenus à l'aide d'un support (100) et formant un arc de cercle rendu solidaire de la grille arrière (101) (Fig. 2) fermant le carter (10) au moyen de pattes (66). Cette pièce (6) peut être réalisée par moulage en matériau plastique.In an alternative embodiment and as shown in Figures 2 and 3, the part (6) has five conduits (n, n₁, n₂, n₃, n n ) held in place by a support (100) and forming a circular arc made integral with the rear grid (101) (Fig. 2) closing the casing (10) by means of lugs (66). This part (6) can be produced by molding in plastic material.

Un dispositif conforme à l'invention trouve son application notamment pour climatiser des pièces d'habitation, l'intérieur des automobiles, et de manière générale, pour climatiser tout volume devant être maintenu à une température et à un degré d'humidité relativement constants.A device according to the invention finds its application in particular for air conditioning living spaces, the interior of automobiles, and generally for air conditioning any volume to be maintained at a relatively constant temperature and humidity.
