Abstract
Description
Nouveau dispositif de récupération de l'eau dans les installations domestiques et son utilisation La présente invention se rapporte au domaine des nécessités dans la vie et plus particulièrement au domaine des installations de distribution de l'eau domestique. Elle a plus précisément pour objet un nouveau dispositif de récupération de l'eau dans les installations sanitaires ou hygiéniques domestiques de distribution de l'eau chaude, notamment sur les lavabos, les éviers, les cabines de douche, les baignoires, les buanderies et les laveries. The present invention relates to the field of necessities in life and more particularly to the field of domestic water distribution installations. More specifically, it relates to a new device for recovering water in domestic sanitary or hygienic hot water distribution installations, in particular on washbasins, sinks, shower stalls, baths, laundry rooms and washrooms. laundries.
Spécifiquement la présente invention se rapporte à un dispositif destiné à stocker temporairement l'eau qui, lorsqu'elle n'a pas été soutirée depuis un certain temps, a refroidi dans la canalisation reliant l'équipement de production d'eau chaude et le point de prélèvement et ensuite il la redistribue en priorité dès que de l'eau froide est soutirée. Specifically, the present invention relates to a device for temporarily storing water which, when it has not been withdrawn for some time, has cooled in the pipe connecting the hot water production equipment and the point sampling and then redistribute it as soon as cold water is withdrawn.
Pour des raisons de confort, certaines grandes installations (hôtels, immeubles collectifs, etc...) sont équipées de systèmes de circulation continue d'eau chaude qui permettent d'avoir en permanence de l'eau chaude à proximité des points de prélèvement (généralement : cuisines, salles d'eau, etc...). Ce dispositif fonctionne à l'aide d'un circulateur électrique qui consomme de l'énergie et implique d'avoir une conduite de retour supplémentaire et ce pour chaque point de prélèvement, selon le schéma de la figure n°1 jointe en annexe. For reasons of comfort, some large installations (hotels, multi-family buildings, etc.) are equipped with continuous hot water circulation systems that allow hot water to be kept close to the sampling points ( usually: kitchens, bathrooms, etc ...). This device operates using an electric circulator that consumes energy and involves having an additional return line and this for each sampling point, according to the diagram of Figure No. 1 attached.
Malheureusement, ceci n'est généralement pas le cas dans les habitations individuelles où, l'utilisateur qui a besoin de soutirer de l'eau chaude, laisse couler l'eau dans l'évier ou le bac de douche en passant la main au travers du jet jusqu'à l'obtention de la température désirée. Cette eau, froide ou tiède mais propre, part directement à l'égout par le siphon sans avoir été utilisée. Unfortunately, this is usually not the case in single-family homes where the user who needs to draw off hot water, lets the water flow into the sink or shower tray by passing the hand through from the jet until the desired temperature is reached. This water, cold or warm but clean, goes directly to the sewer by the siphon without having been used.
Au fil des jours, cela représente un volume d'eau gaspillée considérable. Il est directement proportionnel à plusieurs paramètres qui sont principalement : • La longueur de tuyauterie concernée. • La qualité de son isolation thermique. • La température ambiante extérieure à cette tuyauterie. • La récurrence à laquelle est utilisée l'eau chaude. Over the days, this represents a considerable amount of wasted water. It is directly proportional to several parameters which are mainly: • The length of piping concerned. • The quality of its thermal insulation. • The ambient temperature outside this piping. • The recurrence at which hot water is used.
Certains utilisateurs plus économes récupèrent cette eau dans un récipient propre afin de l'utiliser ultérieurement dès qu'ils auront besoin d'eau froide. Cependant cette façon de procéder n'est pas générale et laisse en suspens le souci essentiel d'économiser l'eau. Some more efficient users collect this water in a clean container for later use as soon as they need cold water. However this way of proceeding is not general and leaves in suspense the essential concern to save water.
Il existait donc un problème de distribution de l'eau domestique avec le souci de limiter les dépenses en eau. There was therefore a problem of distribution of domestic water with the concern to limit water expenses.
Le dispositif, selon l'invention, permet principalement de rediriger l'eau de puisage encore froide, vers un récipient de stockage étanche situé en dérivation sur le circuit d'eau froide en amont du point de prélèvement. Cette eau ainsi stockée ne sort pas par le robinet et n'est donc pas déversée dans l'égout. Ensuite le même dispositif redistribue cette eau en priorité dès qu'on soutire de l'eau froide au robinet. L'eau est ainsi stockée pour de très courtes durées, ce qui écarte les risques de développement de contaminations de type légionellose ou autres bactéries. Le dispositif a l'avantage de ne pas avoir besoin d'autre énergie que la pression déjà présente dans le circuit sanitaire. The device, according to the invention, mainly allows to redirect the still cold water to a sealed storage container located bypass on the cold water circuit upstream of the sampling point. This stored water does not come out of the tap and is not discharged into the sewer. Then the same device redistributes this water first as soon as cold tap water is withdrawn. The water is thus stored for very short durations, which eliminates the risk of developing contaminations of legionella type or other bacteria. The device has the advantage of not needing any other energy than the pressure already present in the sanitary circuit.
Le dispositif selon l'invention peut être décliné sous diverses configurations qui le cas échéant, ne nécessitent que des modifications limitées de l'installation existante de l'habitation. The device according to the invention can be declined in various configurations which, if necessary, require only limited modifications of the existing installation of the dwelling.
Le dispositif selon l'invention se caractérise donc par la présence de trois éléments principaux qui opèrent conjointement ou successivement pour résoudre le problème énoncé ci-dessus : 1. Un élément de régulation de pression (1) installé le long de la conduite d'eau froide, en amont des robinets et du récipient de stockage décrit ci-dessous. Cet élément, grâce à son mode de conception, fait aussi fonction de clapet anti-retour. 2. Un récipient de stockage (2) étanche, d'un volume adapté à la longueur de tuyau à purger et à réchauffer . Il est installé en dérivation le long de la conduite d'eau froide et en aval du régulateur de pression (1). Cet élément peut être assimilé à un vase d'expansion équipé d'une vessie interne ou membrane (4), pourvu qu'il soit de qualité sanitaire (ACS) et qu'il réponde aux exigences des normes relatives aux équipements sous pression (DESP). La vessie peut par exemple être en caoutchouc Butyle alimentaire et la paroi interne peut posséder un revêtement ou une peinture époxy alimentaire. La vessie (4) (ou membrane) est pré-gonflée avec un gaz compressible, généralement de l'azote mais aussi de l'air, le gaz carbonique, les gaz rares et/ou le Fréon, à une pression égale ou légèrement supérieure à la pression du circuit d'eau froide et occupe tout le volume intérieur du récipient de stockage. 3. Un élément de dérivation (3) reliant les conduites d'eau chaude et d'eau froide. Il est idéalement placé au plus près du point de prélèvement. Il comporte un moyen de manoeuvre dont les commandes d'ouverture et de fermeture sont manuelles, semi-automatiques ou automatiques. Afin de réduire la distance au maximum, cet élément est de préférence intégré au robinet quelque soit son type (robinet, mitigeur, vanne, robinet thermostatique, etc...). L'élément de dérivation est de préférence équipé d'une commande à enclenchement et déclenchement thermostatique. The device according to the invention is therefore characterized by the presence of three main elements that operate jointly or successively to solve the problem stated above: 1. A pressure regulating element (1) installed along the water pipe cold, upstream of the faucets and the storage container described below. This element, thanks to its design, also acts as a non-return valve. 2. A sealed storage container (2) of a volume adapted to the length of pipe to be purged and heated. It is installed as a bypass along the cold water line and downstream of the pressure regulator (1). This element can be likened to an expansion vessel equipped with an internal bladder or membrane (4), provided that it is of sanitary quality (ACS) and that it meets the requirements of the standards for pressure equipment (PED). ). The bladder may for example be butyl rubber food and the inner wall may have a coating or epoxy food paint. The bladder (4) (or membrane) is pre-inflated with a compressible gas, usually nitrogen but also air, carbon dioxide, rare gases and / or Freon, at equal or slightly greater pressure at the pressure of the cold water circuit and occupies the entire interior volume of the storage container. 3. A bypass element (3) connecting the hot and cold water pipes. It is ideally placed closer to the point of sampling. It comprises a maneuvering means whose opening and closing commands are manual, semi-automatic or automatic. In order to reduce the distance to the maximum, this element is preferably integrated in the tap whatever its type (faucet, mixing valve, valve, thermostatic valve, etc ...). The bypass element is preferably equipped with a thermostatic engagement and tripping control.
Dans le cas où un seul robinet d'eau entre en ligne de compte, le dispositif selon l'invention est conçu d'une manière compacte et est logé à proximité d'un élément de puisage (par exemple placé dans un meuble sous un évier de cuisine ou un lavabo, ou encore intégré dans une colonne de douche ou de lavabo). L'équipement est monté en ligne entre les arrivées d'eau et le robinet et aucune modification de la tuyauterie n'est à prévoir si les raccordements sont effectués par flexibles avec raccords à visser. In the case where a single water tap is taken into account, the device according to the invention is designed in a compact manner and is housed near a drawing element (for example placed in a cabinet under a sink kitchen or sink, or built into a shower or sink column). The equipment is mounted in-line between the water inlets and the tap and no modification of the piping is to be expected if the connections are made by hoses with screw connections.
Dans le cas d'une installation multiple dans laquelle plusieurs points de prélèvement de l'eau chaude doivent être pris en compte comme par exemple dans une maison d'habitation, dans un immeuble comportant une multiplicité d'appartements, dans un hôtel ou dans un lieu d'hébergement, le dispositif peut être séparé et dans ce cas, le régulateur de pression (1) est à installer en amont de tous les robinets à prendre en compte. Le récipient de stockage (2) est à installer en dérivation sur la conduite d'eau froide reliant tous les robinets situés en aval du régulateur de pression (1) et on doit trouver un élément de dérivation (3) au pied de chaque point de prélèvement. In the case of a multiple installation in which several points for taking hot water must be taken into account, for example in a dwelling house, in a building with a multiplicity of apartments, in a hotel or in a building. accommodation, the device can be separated and in this case, the pressure regulator (1) is to be installed upstream of all the faucets to be taken into account. The storage container (2) is to be installed as a bypass on the cold water line connecting all the valves located downstream of the pressure regulator (1) and a bypass element (3) must be located at the foot of each pressure point. sample.
Selon des modes particuliers de réalisation de l'invention le dispositif peut être défini de la manière suivante : (Les valeurs étant données à titre d'exemple afin de faciliter la compréhension du système) According to particular embodiments of the invention the device can be defined as follows: (The values being given by way of example in order to facilitate understanding of the system)
À l'état initial : La pression P1 du circuit d'eau chaude est d'environ 4bar; La pression P2 du circuit d'eau froide est régulée par le régulateur de pression (1) taré de façon à ce que P2 soit sensiblement inférieure à PI (ex. P2 = environ 2bar) ; Tous les robinets (8 et 9) sont fermés ; Tous les robinets de dérivation (3) sont fermés ; La pression interne P3 de la vessie (4) du récipient de stockage (2) est égale ou légèrement supérieure à la pression P2 du circuit d'eau froide (soit environ 2bar) ; Le volume du récipient de stockage (2) est occupé par la vessie (4) et ne contient pas d'eau ; Il existe une différence de pression égale à Pl û P2 entre l'amont et l'aval de chaque robinet de dérivation (3) (soit environ 2bar). In the initial state: The pressure P1 of the hot water circuit is about 4bar; The pressure P2 of the cold water circuit is regulated by the pressure regulator (1) calibrated so that P2 is substantially less than P1 (eg P2 = about 2 bar); All faucets (8 and 9) are closed; All bypass valves (3) are closed; The internal pressure P3 of the bladder (4) of the storage container (2) is equal to or slightly greater than the pressure P2 of the cold water circuit (ie approximately 2 bar); The volume of the storage container (2) is occupied by the bladder (4) and does not contain water; There is a difference in pressure equal to Pl-P2 between the upstream and downstream of each bypass valve (3) (about 2bar).
En fonctionnement : Avant d'ouvrir le robinet d'eau chaude (8), l'utilisateur actionne le dispositif en ouvrant le robinet de dérivation (3). Le circuit d'eau chaude étant toujours alimenté à la pression Pl par l'équipement de production d'eau chaude (5), un transfert d'eau se fait depuis la conduite d'eau chaude vers la conduite d'eau froide. La pression du circuit d'eau froide P2 s'élève en aval du régulateur de pression (1) qui stoppe donc l'arrivée d'eau froide. Le régulateur de pression (1) fait également office de clapet anti-retour et empêche l'eau transférée de rétrograder en amont de celui-ci. Enfin le gaz contenu dans la vessie (4) étant compressible, sous l'effet de la montée de pression du circuit d'eau froide, il diminue de volume et libère ainsi de l'espace pour l'eau froide qui vient de la conduite d'eau chaude. In operation: Before opening the hot water tap (8), the user actuates the device by opening the bypass tap (3). Since the hot water circuit is always supplied at the pressure P1 by the hot water production equipment (5), water is transferred from the hot water pipe to the cold water pipe. The pressure of the cold water circuit P2 rises downstream of the pressure regulator (1) which therefore stops the cold water supply. The pressure regulator (1) also serves as a non-return valve and prevents the transferred water from downshifting upstream of it. Finally, the gas contained in the bladder (4) is compressible, under the effect of the pressure rise of the cold water circuit, it decreases in volume and thus frees up space for the cold water that comes from the pipe hot water.
Au bout de quelques secondes, l'eau chaude, issue de l'équipement de production d'eau chaude (5), arrive au robinet de dérivation (3) et donc en pied de robinet d'eau chaude (8). Si le robinet de dérivation (3) n'est pas fermé au préalable, le circuit d'eau froide ainsi que la vessie (4) atteignent la pression P 1 d'environ 4bar. Si le système n'est pas équipé de commandes automatiques, l'utilisateur peut alors refermer le robinet de dérivation (3) et ouvrir le robinet d'eau chaude (8) qui coule alors spontanément. Le transfert d'eau s'effectue tant que la pression dans la vessie est inférieure à la pression P1. Le volume du récipient de stockage (2) est à adapter à l'importance de l'installation. After a few seconds, the hot water from the hot water production equipment (5) arrives at the bypass tap (3) and thus at the bottom of the hot water tap (8). If the bypass valve (3) is not closed beforehand, the cold water circuit and the bladder (4) reach the pressure P 1 of about 4bar. If the system is not equipped with automatic controls, the user can then close the bypass tap (3) and open the hot water tap (8) which then flows spontaneously. The transfer of water takes place as long as the pressure in the bladder is below the pressure P1. The volume of the storage container (2) is to be adapted to the importance of the installation.
A l'ouverture du robinet d'eau froide, (9) le circuit se retrouve à l'air libre et donc à la pression atmosphérique, ce qui permet à la vessie (4) de se détendre et de reprendre sa place dans le récipient de stockage (2) tout en repoussant l'eau contenue dans celui-ci. Le régulateur de pression (1) ne va délivrer de l'eau froide que lorsque la pression en aval sera redescendue en dessous de la pression P2, c'est-à-dire quand le récipient de stockage (2) sera vide. At the opening of the cold water tap, (9) the circuit is found in the open air and therefore at atmospheric pressure, which allows the bladder (4) to relax and resume its place in the container. storage (2) while repelling the water contained therein. The pressure regulator (1) will only deliver cold water when the downstream pressure has fallen below the pressure P2, that is to say when the storage container (2) is empty.
