La présente invention concerne une enceinte frigorifique amovible et transportable dans un véhicule
Elle se rapporte plus particulièrement à une enceinte frigorifique apte à être aisément transportable sur des longs trajets via un véhicule, notamment automobile, tout en conservant sa température intérieure adapté aux denrées qu'elle contient
On connaît déjà des véhicules automobiles ou des camions équipés d'un système classique de réfrigération destiné à permettre le transport de denrées notamment alimentaires sur des longs trajets. Ce type de véhicules donne entière satisfaction mais nécessite pour des raisons de coût, le transport d'un volume important de denrées, nécessitant ainsi de faire appel à des sociétés spécialisées ou d'investir dans l'achat d'un tel véhicule
En outre Il s'avère, en cas d'avarie du véhicule, nécessaire de décharger la cargaison afin de la disposer dans un second véhicule de même type ce qui, outre le coût, peut occasionner une rupture de la chaîne du froid et par conséquent la détérioration de la qualité des denrées alimentaires, voire leur perte
Le but de l'invention est de proposer une enceinte frigorifique amovible et apte à être transportée au moyen d'un véhicule qui permette de résoudre tout ou partie des inconvénients précités
A cet effet, la présente invention a pour objet une enceinte frigorifique amovible et transportable dans un véhicule, notamment utilitaire, ladite enceinte comprenant un organe producteur de froid apte à être alimenté en courant alternatif à partir d'une prise murale lorsque ce dernier est déposé sur site, caractérisée en ce qu'elle comprend en outre un dispositif de pilotage de la gestion d'énergie à fournir à l'organe producteur de froid pour maintenir l'intérieur de l'enceinte à une température minimale apte à relier credit organe à une source de courant continu basse tension disponible dans le véhicule en fonction des paramètres d'état de la source de tension et de la température intérieure de l'enceinte
Suivant quelques dispositions intéressantes de l'invention - le dispositif de pilotage est constitué d'un calculateur relié d'une part à The present invention relates to a removable and transportable refrigeration enclosure in a vehicle
It relates more particularly to a refrigeration enclosure capable of being easily transportable over long journeys via a vehicle, in particular a motor vehicle, while retaining its internal temperature adapted to the foodstuffs which it contains.
Motor vehicles or trucks are already known which are fitted with a conventional refrigeration system intended to allow the transport of foodstuffs, in particular foodstuffs, over long journeys. This type of vehicle gives full satisfaction but requires for cost reasons, the transport of a large volume of food, thus requiring to call on specialized companies or to invest in the purchase of such a vehicle
In addition It turns out, in the event of damage to the vehicle, it is necessary to unload the cargo in order to have it in a second vehicle of the same type which, in addition to the cost, can cause a break in the cold chain and consequently the deterioration of the quality of foodstuffs, or even their loss
The object of the invention is to provide a removable refrigerating enclosure capable of being transported by means of a vehicle which makes it possible to resolve all or part of the aforementioned drawbacks
To this end, the subject of the present invention is a removable refrigerating enclosure which can be transported in a vehicle, in particular a utility vehicle, said enclosure comprising a cold producing member capable of being supplied with alternating current from a wall outlet when the latter is removed. on site, characterized in that it further comprises a device for controlling the energy management to be supplied to the cold-producing member in order to maintain the interior of the enclosure at a minimum temperature capable of connecting credit member to a low voltage direct current source available in the vehicle as a function of the voltage source state parameters and the interior temperature of the enclosure
According to some interesting provisions of the invention - the control device consists of a computer connected on the one hand to

- the values only! s preferred! n) es consist of a minimum temperature value and a minimum value of available battery charge and in that the minimum battery charge value takes precedence over the minimum temperature value so that below this threshold, the supply of the cold producing organ is prohibited, - the minimum temperature value is a negative temperature value, preferably equal to minus 18 degrees Celsius.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, en se référant à la figure unique annexée sur laquelle est schématisé le circuit électrique d'une enceinte frigorifique selon la présente invention
On peut voir sur cette figure la représentation schématique d'une enceinte frigorifique 1 disposée à l'intérieur d'un véhicule automobile 2 par exemple un véhicule utilitaire. The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, with reference to the attached single figure in which the electrical circuit d '' a refrigeration chamber according to the present invention
We can see in this figure the schematic representation of a refrigeration enclosure 1 arranged inside a motor vehicle 2, for example a utility vehicle.

Cette enceinte 1 est constitué de manière classique d'un organe producteur de froid 3 tel que par exemple un compresseur associé à un évaporateur 4. Ce compresseur 3 est apte à être alimenté en courant alternatif à partir d'une prise murale 5 classique lorsqu'il est déposé sur site.  This enclosure 1 is conventionally constituted by a cold producing member 3 such as for example a compressor associated with an evaporator 4. This compressor 3 is able to be supplied with alternating current from a conventional wall outlet 5 when it is deposited on site.

Selon la présente invention, ce compresseur 3 est également apte à être alimenté en courant continu basse tension disponible dans le véhicule au moyen d'un dispositif de pilotage 6 de la gestion d'énergie à fournir au compresseur pour maintenir l'intérieur de l'enceinte 1 à une température minimale.  According to the present invention, this compressor 3 is also able to be supplied with low-voltage direct current available in the vehicle by means of a device 6 for controlling the energy management to be supplied to the compressor to maintain the interior of the enclosure 1 at a minimum temperature.

Ce dispositif de pilotage 6 permet ainsi de transformer le courant basse tension de l'ordre de 12 ou 24 Volts fourni par au moins une battene 7 afin d'alimenter correctement le compresseur 3 lors du transport de l'enceinte frigorifique 1.  This control device 6 thus makes it possible to transform the low voltage current of the order of 12 or 24 Volts supplied by at least one battery 7 in order to correctly supply the compressor 3 during the transport of the refrigerating chamber 1.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

A cet effet, le dispositif 6 est relié au moyen de cordons électriques 8 aux bornes de la batterie 7 du véhicule qui, de manière connue, est associée à l'alternateur 9 constituant en partie le groupe motopropulseur du véhicule.  To this end, the device 6 is connected by means of electrical cords 8 to the terminals of the battery 7 of the vehicle which, in known manner, is associated with the alternator 9 constituting in part the powertrain of the vehicle.

Le dispositif de pilotage 6 est constitué d'un transformateur 10 du courant continu en courant alternatif afin de permettre l'alimentation du compresseur 3 et d'un calculateur 11 permettant la mise sous tension ou non du compresseur 3 en fonction de différents paramètres établissant l'état du système composé de l'enceinte et du véhicule
Ainsi, le calculateur 11 reçoit des informations transmises d'une part par une sonde thermique 12 disposée à l'intérieur de l'enceinte et d'autre part par un capteur de la charge de la batterie, non représenté. Ce calculateur 11 est avantageusement relié également à un moyen de détection, non schématisé, du type d'énergie, courant alternatif ou continu alimentant l'enceinte frigorifique
Le calculateur 11 compare les différents paramètres (type d'énergie, température, valeur de la charge batterie) qui lui sont transmis périodiquement aux différentes valeurs seuils de déclenchement d'une alimentation ou non. The control device 6 consists of a transformer 10 from direct current to alternating current in order to allow the supply of the compressor 3 and of a computer 11 allowing the compressor 3 to be powered up or not depending on different parameters establishing the state of the system consisting of the enclosure and the vehicle
Thus, the computer 11 receives information transmitted on the one hand by a thermal probe 12 disposed inside the enclosure and on the other hand by a battery charge sensor, not shown. This computer 11 is advantageously also connected to a means of detection, not shown diagrammatically, of the type of energy, alternating or direct current supplying the refrigeration enclosure.
The computer 11 compares the different parameters (type of energy, temperature, value of the battery charge) which are transmitted to it periodically with the different threshold values for triggering a supply or not.

Ces valeurs seuils sont constituées d'une valeur minimale de température Tmin et d'une valeur minimale de charge de batterie disponible Ubat.  These threshold values consist of a minimum temperature value Tmin and a minimum battery charge value available Ubat.

Cette valeur minimale de charge de batterie Ubat est prioritaire par rapport à la valeur minimale de température Tmin et est définie de telle sorte qu'en dessous de ce seuil, l'alimentation du compresseur est interdite afin de donner la priorité au bon fonctionnement du véhicule.  This minimum battery charge value Ubat has priority over the minimum temperature value Tmin and is defined so that below this threshold, compressor power is prohibited in order to give priority to the proper functioning of the vehicle .

Selon un mode de réalisation préféré non limitatif, le dispositif de pilotage 6 permet de maintenir à intérieur de l'enceinte une température négative, dont la valeur minimale est de préférence égale à moins 18 degrés Celsius.  According to a preferred nonlimiting embodiment, the control device 6 makes it possible to maintain inside the enclosure a negative temperature, the minimum value of which is preferably equal to minus 18 degrees Celsius.

Le fonctionnement du dispositif de pilotage de l'enceinte frigorifique selon la présente invention qui découle de manière évidente de la description cidessus, va maintenant être explicité en relation avec la figure unique.  The operation of the device for controlling the refrigeration chamber according to the present invention, which clearly follows from the description above, will now be explained in relation to the single figure.

L'utilisateur désireux de transporter ses denrées alimentaires par exemple entreposées à l'intérieur de l'enceinte frigorifique déposée dans son local dans un second local situé à distance, déplace l'enceinte dans un véhicule automobile du type utilitaire et relie le dispositif de pilotage à la batterie au moyen du cordon  The user wishing to transport his foodstuffs, for example stored inside the refrigerated enclosure deposited in his room in a second room located at a distance, moves the enclosure in a motor vehicle of the utility type and connects the control device to the battery by means of the cord

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

Au cours du trajet, le calculateur reçoit périodiquement les informations de température de l'intérieur de l'enceinte frigorifique et de la charge de la batterie. During the journey, the computer periodically receives temperature information from the interior of the refrigeration chamber and from the battery charge.

Dans le cas où la température de l'enceinte est en dessous du seuil Tmin et que la charge de la batterie Ubat est suffisante, le calculateur active le compresseur jusqu'à ce que sa température chute dans une fourchette de températures souhaitées
Lors de cette manoeuvre, le calculateur 11 surveille constamment la valeur de la charge de batterie afin éventuellement de désactiver le compresseur 3 dans le cas où la valeur de charge atteint la valeur minimale nécessaire au bon fonctionnement du véhicule. In the event that the temperature of the enclosure is below the threshold Tmin and that the charge of the Ubat battery is sufficient, the computer activates the compressor until its temperature drops within a range of desired temperatures
During this maneuver, the computer 11 constantly monitors the value of the battery charge in order to possibly deactivate the compressor 3 in the event that the charge value reaches the minimum value necessary for the proper functioning of the vehicle.

Arrivé à destination, l'utilisateur décharge l'enceinte frigorifique et alimente le compresseur en courant alternatif à partir d'une prise murale.  When they reach their destination, the user unloads the refrigeration chamber and supplies the compressor with alternating current from a wall outlet.

On comprend également qu'en cas d'arrêt du véhicule, le dispositif de pilotage continue de contrôler et de piloter la température intérieure de l'enceinte.  It is also understood that in the event of the vehicle stopping, the control device continues to control and control the interior temperature of the enclosure.

Selon une variante de réalisation, le dispositif de pilotage est relié à l'intérieur du véhicule à au moins une batterie supplémentaire 14 relié à la batterie du véhicule afin d'être rechargée éventuellement par l'alternateur 9.  According to an alternative embodiment, the control device is connected inside the vehicle to at least one additional battery 14 connected to the vehicle battery so as to be possibly recharged by the alternator 9.

Afin de permettre une manipulation aisée de l'enceinte lors des phases de chargement et déchargement, ladite enceinte repose sur des roulettes 13 dont au moins une comporte un frein.  In order to allow easy handling of the enclosure during the loading and unloading phases, said enclosure rests on rollers 13, at least one of which includes a brake.

On comprend à la lecture de la description ci-dessus que l'enceinte frigorifique selon la présente invention est relativement simple à réaliser et permet avantageusement de ne pas rompre la chaîne du froid des denrées alimentaires En outre, on comprend également que du fait que l'enceinte soit aisément amovible, ceci ne nécessite pas une manipulation fastidieuse des denrées contrairement aux solutions classiques
Par ailleurs, cette enceinte permet de s'affranchir de tout risque de perte des denrées alimentaires dû à une avarie du véhicule les transportant. It will be understood from reading the description above that the refrigerating chamber according to the present invention is relatively simple to produce and advantageously makes it possible not to break the cold chain of foodstuffs. In addition, it is also understood that due to the fact that the enclosure is easily removable, this does not require tedious handling of the food unlike conventional solutions
In addition, this enclosure eliminates any risk of loss of foodstuffs due to damage to the vehicle transporting them.

Bien que l'invention ait été décrite en liaison avec deux modes de réalisation particuliers elle comprend tous les équivalents techniques des moyens décrits Although the invention has been described in conjunction with two particular embodiments, it includes all the technical equivalents of the means described
