Description

Installation de transfert de fluide frigorigène des installations Installation of refrigerant transfer from installations
frigorifiques par pompe à chaleur. heat pump refrigerators.
L'invention a pour objet une installation de transfert de fluide frigorigene des installations frigorifiques, par pompe à chaleur. The subject of the invention is an installation for transferring refrigerant from refrigerating installations, by heat pump.
On connait déjà des installations de vidange du fluide d'installations frigorifiques comportant un groupe de transfert équipé d'un compresseur aspirant le gaz de l'installâtion.De tels dispositifs ne donnent pas toute satisfaction en raison des problèmes posés par la lubrification du compresseur.  There are already known installations for draining the fluid from refrigeration installations comprising a transfer group equipped with a compressor sucking the gas from the installation. Such devices are not entirely satisfactory because of the problems posed by the lubrication of the compressor.
On a proposé également des pompes de transfert de liquide pour vidanger les réserves de liquide frigorigene des groupes de froid.Les risques de cavitation de la pompe et la non possibilité de récupérer le gaz en rend difficile l'utilisation.  Liquid transfer pumps have also been proposed to drain the refrigerant reserves from the refrigeration units. The risks of cavitation of the pump and the inability to recover the gas makes it difficult to use.
Lorsque les installations actuelles sont utilisées pour récupérer le fluide des installations frigorifiques, des tuyauteries d'équilibrage de gaz sont nécessaires rendant complexe la récupération et ne permettant pas de l'appliquer à tous les types d'installations frigorifiques, la pesée du fluide récupérée n'est pas souvent très simple à effectuer et les risques de remplissage excessif des bouteilles de récupération peuvent rendre l'opération dangereuse.  When current installations are used to recover the fluid from refrigeration installations, gas balancing pipes are necessary, making recovery complex and not allowing it to be applied to all types of refrigeration installations, weighing the recovered fluid n It is not often very simple to perform and the risks of overfilling the recovery bottles can make the operation dangerous.
Par ailleurs on a également proposé des systèmes de charge en fluide frigorigene des installations frigorifiques celles ci ne permettent pas d'utiliser directement les bouteilles fournies par les fabricants de fluide ou se contentent d'une pesée et éventuellement d'un réchauffage électrique de la bouteille de fluide.Les systèmes de charge actuels nécessitent le plus souvent un transvasement du fluide dans un autre récipient tel un cylindre de charge.La complexité des procédés actuellement utilisés pour la charge ou la vidange des fluides frigorigèneε conduit le plus souvent à des pertes de gaz ou de liquide frigorigene, ce qui a des effets très néfastes sur l'environnement avec la destruction de la couche d'ozone et l'augmentation de l'effet de serre.  In addition, refrigerant charging systems have also been proposed for refrigeration installations, these do not allow the bottles supplied by the fluid manufacturers to be used directly or are content with weighing and possibly electric heating of the bottle. Current charging systems most often require a transfer of the fluid to another container such as a charging cylinder. The complexity of the processes currently used for charging or draining refrigerants most often leads to gas losses. or refrigerant, which has very harmful effects on the environment with the destruction of the ozone layer and the increase in the greenhouse effect.
C'est d'une manière générale un but de l'invention de fournir une installation qui ne présente pas les inconvénients, rappelés ci dessus des installations connues.  It is generally an object of the invention to provide an installation which does not have the drawbacks, recalled above of known installations.
C'est en particulier un but de l'invention de fournir une installation de charge permettant de chauffer la bouteille de fluide frigorigène grâce à une pompe à chaleur et d'en effectuer simultanément la pesée. It is in particular an object of the invention to provide a charging installation for heating the bottle of refrigerant using a heat pump and weighing it simultaneously.
C'est encore un but de l'invention de fournir une installation de vidange permettant de refroidir la bouteille de fluide de récupération grâce à une pompe à chaleur, et d'en effectuer simultanément la pesée.  It is also an object of the invention to provide a drainage installation making it possible to cool the bottle of recovery fluid using a heat pump, and to simultaneously weigh it.
Une installation de transfert de fluide frigorigene selon l'invention, est caractérisée en ce qu'elle comporte un système de pompe à chaleur permettant de refroidir ou de réchauffer une bouteille standard, par convection, au moyen d'un circuit d'air comportant un ventilateur, un echangeur et une enceinte dans laquelle se place la bouteille.  A refrigerant transfer installation according to the invention is characterized in that it comprises a heat pump system making it possible to cool or heat a standard bottle, by convection, by means of an air circuit comprising a ventilator, an exchanger and an enclosure in which the bottle is placed.
Selon une autre caractéristique de l'invention le socle de l'enceinte comporte une bascule permettant de poser la bouteille de fluide et d'en effectuer la pesée.  According to another characteristic of the invention, the base of the enclosure comprises a rocker making it possible to place the bottle of fluid and to weigh it.
Selon une autre carastéristique de l'invention un second echangeur permet de réaliser le transfert de chaleur de la bouteille à l'air ambiant.  According to another characteristic of the invention, a second exchanger makes it possible to carry out heat transfer from the bottle to the ambient air.
L'invention sera bien comprise par la description qui suit faite à titre d'exemple et en référence aux dessins annexés dans lequel:  The invention will be better understood from the following description given by way of example and with reference to the appended drawings in which:
- La figure 1 est un schéma d'une installation selon  - Figure 1 is a diagram of an installation according
l'invention représentée en cycle vidange.  the invention shown in the drain cycle.
- La figure 2 est un schéma d'une installation selon l'invention représentée en cycle charge.  - Figure 2 is a diagram of an installation according to the invention shown in charge cycle.
- La figure 3 est une vue de dessus en coupe permettant de voir la distribution d'air.  - Figure 3 is a top view in section to see the air distribution.
Une installation de transfert de fluide selon l'invention figure l,est montée sur un châssis 17, elle comprend un echangeur 10 jouant le rôle d'évaporateur sur lequel circule de l'air brassé par un ventilateur 11. L'echangeur 10 fait partie intégrante d'un circuit de pompe à chaleur comprenant un compresseur 12 qui aspire les gaz dans l'évapcrateur et les refoule dans un echangeur extérieur 13 jouant alors le rôle de condenseur. Ce dernier rejette la chaleur à l'air ambiant grâce au au ventilateur 14. Le liquide formé passe par la tuyauterie 25 puis est détendu dans le détendeur 16 avant d'être envoyé par la tuyauterie 20 dans l'évapcrateur 10. Ce dernier produit du froid ce qui vaporise le liquide.Le gaz formé est admis dans la tuyauterie 21 puis pénètre dans la vanne 4 voies 15 où le clapet 26 le dirige vers la tuyauterie 22 pour être aspiré par le compresseur 12. Celui ci refoule les gaz dans la tuyauterie 23 puis la vanne 4 voies les dirige vers le condenseur 13 où le liquide formé fera ensuite un nouveau cycle. L'installation de transfert est de type monobloc et assure le refroidissement d'une bouteille de récupération de fluide 30, ce qui fait baisser la pression à l'intérieur de la bouteille, celle ci comporte une vanne 34 et une sortie 35 que l'on raccordera par l'intermédiaire d'un flexible 36 à l'installation frigorifique à vidanger F. L'installation frigorifique étant à une température supérieure à celle de la bouteille 30 se vidangera d'elle même en phase liquide ou gazeuse vers la bouteille 30 où le liquide frigorigene récupéré sera stocké. Notons que la bouteille 30 est placée sur le plateau 40 d'une bascule 41,permettant ainsi de contrôler grâce à l'indicateur numérique 42 le poids de la bouteille, donc la masse de fluide récupéré. Afin de ne pas perdre de froid, l'enceinte E, dans laquelle se trouve la bouteille 30, est calorifugée par une enveloppe amovible 31. Un couvercle 32 est prévu afin de permettre le passage du flexible 36 et d'autoriser l'utilisation de bouteilles de récupération plus grandes que l'appareil de transfert; dans ce cas, on retire le couvercle 32, et la bouteille dépasse en partie supérieure. La vidange de l'installation frigorifique se réalise naturellement grâce à l'écart de pression créé par le refroidissement de la bouteille 30. A fluid transfer installation according to the invention in FIG. 1, is mounted on a chassis 17, it includes an exchanger 10 playing the role of evaporator on which air circulated by a fan 11. The exchanger 10 is part integral to a heat pump circuit comprising a compressor 12 which sucks the gases in the evaporator and discharges them into an external exchanger 13 while playing the role of condenser. The latter rejects the heat to the ambient air thanks to the fan 14. The liquid formed passes through the pipe 25 then is expanded in the pressure reducer 16 before being sent through the pipe 20 into the evaporator 10. The latter produces cold which vaporizes the liquid. The gas formed is admitted into the pipe 21 and then enters the 4-way valve 15 where the valve 26 directs it to the pipe 22 to be sucked by the compressor 12. The latter discharges the gas in the pipe 23 then the 4-way valve directs them to the condenser 13 where the liquid formed will then make a new cycle. The transfer installation is of the monobloc type and ensures the cooling of a fluid recovery bottle 30, which lowers the pressure inside the bottle, the latter comprises a valve 34 and an outlet 35 which the it will be connected via a hose 36 to the refrigeration installation to be drained F. The refrigeration installation being at a temperature higher than that of the bottle 30 will drain itself in liquid or gaseous phase towards the bottle 30 where the recovered refrigerant will be stored. Note that the bottle 30 is placed on the plate 40 of a rocker 41, thus making it possible to control, using the digital indicator 42, the weight of the bottle, therefore the mass of fluid recovered. In order not to lose cold, the enclosure E, in which the bottle 30 is located, is insulated by a removable envelope 31. A cover 32 is provided in order to allow the passage of the flexible 36 and to authorize the use of recovery bottles larger than the transfer device; in this case, the cover 32 is removed, and the bottle protrudes at the top. The refrigeration system is emptied naturally thanks to the pressure difference created by the cooling of the bottle 30.
Dans la configuration de l'invention, figure 2, l'action sur le bouton de commande 43 a pour effet de faire basculer le clapet 26 de la vanne 4 voies 15 dans l'autre position par rapport à celle de la figure 1. Dans la configuration de la figure 2, le rôle des échangeurs 10 et 13 se trouve inversé et dans ce cas l'echangeur 10 joue le rôle de condenseur ce qui a pour effet de chauffer l'air brassé par le ventilateur 11. Le système de transfert est utilisé dans ce cas pour charger l'installation frigorifique à partir d'une bouteille de fluide neuf 60 équipée d'une vanne 64 et d'une sortie 65. Le chauffage de la bouteille 60 a pour effet d'en élever la pression. Celle ci est raccordée à l'installation frigorifique F' à charger, par l'intermédiaire d'un flexible 66. L'installation frigorifique étant à une température inférieure à celle de la bouteille 60, se chargera en fluide frigorigene. La bouteille 60 est placée sur le plateau 40 d'une bascule 41 permettant ainsi de contrôler la masse de fluide injectée dans l'installation F' grâce à l'indicateur numérique 42. La charge s'effectue naturellement grâce à l'écart de pression créé par le chauffage de la bouteilleIn the configuration of the invention, Figure 2, the action on the control button 43 has the effect of tilting the valve 26 of the 4-way valve 15 in the other position relative to that of Figure 1. In the configuration of FIG. 2, the role of the exchangers 10 and 13 is reversed and in this case the exchanger 10 plays the role of condenser which has the effect of heating the air stirred by the fan 11. The transfer system is used in this case to charge the refrigeration installation from a new fluid bottle 60 fitted with a valve 64 and an outlet 65. Heating the bottle 60 has the effect of raising the pressure. This is connected to the refrigeration installation F 'at charge, via a hose 66. The refrigeration installation being at a temperature lower than that of the bottle 60, will be charged with refrigerant. The bottle 60 is placed on the plate 40 of a rocker 41 thus making it possible to control the mass of fluid injected into the installation F ′ thanks to the digital indicator 42. The charging takes place naturally thanks to the pressure difference created by heating the bottle
60. 60.
La figure 3 représente une vue de dessus en coupe de l'appareil selon l'invention et permet de mieux visualiser les flux d'air et les transferts thermiques. La bouteille 30 se trouve dans une enceinte E isolée thermiquement par les parois 31 et 33. Au passage de l'echangeur 10, l'air passe de la température ta à la température tb, il est ensuite soufflé dans l'enceinte E par le ventilateur 11 sur la bouteille dont l'enveloppe extérieure 70 permet de transmettre la chaleur ou le froid à l'intérieur de la bouteille 30. De l'autre côté de l'appareil, 1 'echangeur extérieur FIG. 3 represents a top view in section of the apparatus according to the invention and makes it possible to better visualize the air flows and the heat transfers. The bottle 30 is located in an enclosure E thermally insulated by the walls 31 and 33. On passing the exchanger 10, the air passes from temperature ta to temperature tb, it is then blown into enclosure E by the fan 11 on the bottle, the outer casing 70 of which transmits heat or cold inside the bottle 30. On the other side of the device, the external exchanger
13 fait passer l'air prélevé dans l'ambiance A de la température te à la température td; le ventilateur 14 le rejette ensuite. Afin de faciliter l'utilisation de l'appareil selon l'invention, la coque extérieure 31 est démontable rapidement grâce à la présence de deux fermetures 50 et 51. 13 causes the air sampled in the atmosphere A to pass from the temperature te to the temperature td; the fan 14 then rejects it. In order to facilitate the use of the device according to the invention, the outer shell 31 is quickly removable thanks to the presence of two closures 50 and 51.
L'invention n'est pas limitée bien sûr à son application pour le transfert de fluide frigorigene en charge ou vidange, elle s'applique également au transfert d'autres types de fluide. Les bouteilles de récupération 30 ou de fluide neuf 60 peuvent être également de différentes formes et dimensions.  The invention is of course not limited to its application for the transfer of refrigerant under load or drain, it also applies to the transfer of other types of fluid. The recovery bottles 30 or new fluid 60 can also be of different shapes and dimensions.
