Description

La présente invention concerne un dispositif permettant une installation facile, rapide, économique et esthétique des compresseurs d'une installation de chauffage ou de climatisation par circuit frigorifique. The present invention relates to a device allowing an easy, fast, economical and aesthetic installation of the compressors of a heating or air conditioning installation by refrigeration circuit.

On connait déja les pompes à chaleur caractérise;es en ce que l'évaporateur est constitué d'épingles horizontales ou verticales enterres à l'extérieur et où le condenseur est constitué d'épingles horizontales noyées directement dans le plancher du local à chauffer. We already know the heat pumps characterized; es in that the evaporator consists of horizontal or vertical pins buried outside and where the condenser consists of horizontal pins embedded directly in the floor of the room to be heated.

L'évaporateur et le condenseur sont généralement constitués de plusieurs épingles raccordées sur plusieurs compresseurs formant ainsi plusieurs circuits frigorifiques complétement séparés pour faciliter la régulation et augmenter la sécurité. The evaporator and the condenser generally consist of several pins connected to several compressors thus forming several completely separate refrigeration circuits to facilitate regulation and increase safety.

Pour chauffer une maison de dimensions moyennes, on réalise entre 2 et 10 circuits frigorifiques indépendants. To heat a medium-sized house, there are between 2 and 10 independent refrigeration circuits.

C'est donc 2 à 10 compresseurs frigorifiques qui doivent être rassemblés en 1 ou 2 endroits. It is therefore 2 to 10 refrigeration compressors which must be gathered in 1 or 2 places.

On peut constater que le raccordement de 2 à 10 compresseurs représente en travail important et difficile par le nombre de tubes à raccorder. We can see that the connection of 2 to 10 compressors represents in important and difficult work by the number of tubes to be connected.

On peut constater que le reroupement des compresseurs en
I ou 2 endroits présente les inconvénients suivants
- les liaisons de tubes sont longues entre le compresseur et la zone qu'il doit chauffer,
- les liaisons rendent difficiles l'utilisation de raccords operculables donc de charge en usine,
- la surface au sol limite le nombre d'emplacements possibles,
- le raccordement des tubes du condenseur et de l'évaporateur est délicat compte tenu du peu d'accéssibilité,
- le service après vente et l'entretien sont également difficile,
- une isolation des tubes est nécessaire sur une grande longueur pour limiter les pertes de chaleur,
- l'isolation des compresseurs est difficile et affecte le coêfficient de performance de l'installation,
- le niveau sonore n'est pas touors négliable,
- la perte d'énergie dans les liaisons n'est pas négligeable.We can see that the grouping of the compressors in
I or 2 places have the following disadvantages
- the tube connections are long between the compressor and the zone which it must heat,
- the connections make it difficult to use sealable fittings, therefore factory-loaded,
- the floor space limits the number of possible locations,
- the connection of the condenser and evaporator tubes is tricky given the poor accessibility,
- after-sales service and maintenance are also difficult,
- tube insulation is required over a long length to limit heat loss,
- the insulation of the compressors is difficult and affects the performance coefficient of the installation,
- the noise level is not negligible,
- the loss of energy in the links is not negligible.

Le dispositif selon l'invention permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

C'est d'une tanière générale un but de l'invention de fournir un appareil qui ne présente pas les inconvenients des appareils connus et rappelés ci-dessus. It is generally a goal of the invention to provide an apparatus which does not have the disadvantages of the known apparatuses and recalled above.

C'est un but de l'invention de fournir un appareil et uninstallation facile à réaliser, esthétique, dissimulant les tubes et dont les performances sont améliorées. It is an object of the invention to provide a device and uninstallation that is easy to carry out, aesthetic, concealing the tubes and whose performance is improved.

C'est un but de l'invention de fournir un appareil standardisé sur lequel peuvent être raccordés indifférement
- une ou plusieurs boucles de tube enterré à 1 'extérieur ou noyé dans la dalle,
- un récupérateur sur les eaux usées pour prélever ou évacuer de la chaleur,
- un réservoir d'eau pouvant être chauffé ou refroidi,
- un radiateur, un connecteur ou un ventilo-convecteur,
- un récupérateur sur l'air extrait d'un logement. It is an object of the invention to provide a standardized device to which can be connected either
- one or more loops of tube buried outside or embedded in the slab,
- a recuperator on waste water to extract or remove heat,
- a water tank that can be heated or cooled,
- a radiator, a connector or a fan coil,
- a recuperator on the air extracted from a dwelling.

Le dispositif selon l'invention est caractérisé en ce que tous les éléments du circuit frigorifique qui ne participent pas à l'échange de chaleur sont regroupés dans une enveloppe étanche, isolée thermiquement et phoniquement. The device according to the invention is characterized in that all the elements of the refrigeration circuit which do not participate in the heat exchange are grouped in a sealed envelope, thermally and phonically insulated.

Cette enveloppe étanche sera généralement placée dans le sol extérieur, près du local à chauffer ou à climatiser. This waterproof envelope will generally be placed in the outside ground, near the room to be heated or air conditioned.

Le dispositif selon l'invention figure 1 comprend une enveloppe 1 en matériau plastique soit isolant thermiquement, soit non isolant. Dans ce dernier cas, une isolation 2 est appliquée sur la paroi intérieure de l'enveloppe 1. A l'intérieur de l'enveloppe 1 se trouvent. compris tous les éléments d'un circuit frigorifique, qui ne participent pas a l'échange de chaleur. Le compresseur 3 refoule le gaz sous pression dans le silencieux 4 connecté à un raccord operculable 5 situé de préférence à la limite de l'enveloppe 1.  The device according to the invention in FIG. 1 comprises an envelope 1 made of plastic material either thermally insulating or non-insulating. In the latter case, insulation 2 is applied to the interior wall of the enclosure 1. Inside the enclosure 1 are located. including all the elements of a refrigeration circuit, which do not participate in the heat exchange. The compressor 3 delivers the pressurized gas into the silencer 4 connected to a sealable connector 5 preferably located at the limit of the envelope 1.

Le raccord operculable 6 reçoit le fluide frigorigéne liquide qui est stockée dans la réserve de liquide 7 puis traverse le déshydrateur et le détendeur 9. Le fluide détendu sera envoyé vers l'évaporateur par l'intermédiaire du raccord operculable 10. A son retour de l'évaporateur, le fluide frigorigéne gazeux arrive au quatriéme raccord operculable 11 puis traverse la bouteille anti-coups 12 de liquide avant d'être aspiré par le compresseur et recommencer un nouveau cycle. L'enveloppe 1 fermée, etanche et isolée thermiquement et phoniquement constitue ainsi un ensemble modulaire pouvant être placé dans différents lieux ou positions et sur lequel on peut raccorde divers évaporateur ou condenseurs. Le circuit selon la figure 1 peut être complété par une vanne d'inversion de cycle.The sealable connection 6 receives the liquid refrigerant which is stored in the liquid reserve 7 then passes through the dehydrator and the pressure reducer 9. The expanded fluid will be sent to the evaporator via the sealable connection 10. On its return from the 'evaporator, the gaseous refrigerant arrives at the fourth sealable connection 11 then passes through the anti-blow bottle 12 of liquid before being sucked in by the compressor and start a new cycle. The closed envelope 1, sealed and thermally and phonically insulated thus constitutes a modular assembly which can be placed in different places or positions and to which various evaporators or condensers can be connected. The circuit according to Figure 1 can be completed by a cycle reversing valve.

L'ensemble selon la figure 1 est nommé module dans la suite de la description.The assembly according to FIG. 1 is named module in the following description.
