Abstract

The air conditioning system uses a centralized network which after adding a heat exchanger and adapting the circuits enables the air conditioning of the premises to retain its original characteristics. The loop uses recovery from town water of the heating or cooling necessary for individual air conditioning. The water is used simultaneously for heating and domestic purposes.

Description

L'invention proposée est destinée à utiliser un réseau de chauffage existant pour alimenter en eau les condenseurs d'un ensemble de climatiseurs réversibles ou non pendant que le chauffage est à l'arrêt.The proposed invention is intended to use an existing heating network to supply water to the condensers of a set of air conditioners, reversible or not, while the heating is off.

La récupération des frigories, et accessoirement des calories pour les systèmes réversibles, s'effectue sur l'eau de ville (E.V) dans la version 1 et sur un forage aquifère pour la version 2. The recovery of frigories, and incidentally calories for reversible systems, is carried out on city water (E.V) in version 1 and on an aquiferous borehole for version 2.

L'invention permet dans sa version 1 (schéma 1) - de rafraîchir 1 ou plusieurs pièces d'une habitation à partir d'un climatiseur individuel eau-air le plus souvent, mais aussi eau-eau, en utilisant les frigories contenues dans l'eau de ville utilisée pour les besoins domestiques avec appoint éventuel en eau perdue. The invention makes it possible in its version 1 (diagram 1) - to cool 1 or more rooms of a dwelling from a room air-water air conditioner most often, but also water-water, by using the frigories contained in the city water used for domestic needs with possible back-up of lost water.

- de chauffer ces mêmes locaux avec un appareil réversible qui, dans ce cas, récupère des calories sur le même réseau, notamment pendant l'intersaison où le chauffage collectif n'est pas en service et où la T"C extérieure nécessite un appoint chauffage pour améliorer les conditions de confort.- to heat these same premises with a reversible device which, in this case, recovers calories from the same network, in particular during the off-season when the collective heating is not in use and where the external T "C requires additional heating to improve comfort conditions.

L'eau de ville n'est pas consommée tant que la T"C du réseau n'atteint pas 25"C. Elle est gratuite lorsque les soutirages d'eau chaude ou d'eau froide sanitaire refroidissent le réseau par passage préalable dans l'échangeur (5). Elle est consommée et rejetée à l'égout lorsqu'aucun soutirage n existe (la nuit par exemple). City water is not consumed until the network T "C reaches 25" C. It is free when the withdrawal of hot water or domestic cold water cools the network by prior passage through the exchanger (5). It is consumed and rejected in the sewer when no racking exists (at night for example).

Version 2 (schéma 2)
Dito version 1 avec non plus de l'eau de ville mais de l'eau d'un forage aquifère si le site le permet. Dans ce cas, la récupération sur l'eau de ville est illusoire. Elle est abandonnée.Version 2 (diagram 2)
Dito version 1 with no longer city water but water from an aquifer if the site allows it. In this case, recovery from city water is illusory. She is abandoned.

Ces climatiseurs individuels eau-air ou plus rarement eau-eau ou encore air-air sont en général utilisés - directement en eau de ville en ce qui concerne les appareils eau-air ou eau-eau à partir d'un robinet de cuisine ou de salle de bain et rejet le plus souvent dans
WC, évier, lavabo, etc... Ces installations nécessitent des liaisons souples qui traversent les locaux avec tous les inconvénients que cela comporte (encombrement, condensation, esthétique...) - en entrebâillant une fenêtre pour évacuer, à l'extérieur, les calories des climatiseurs air-air. Le rendement global (fenêtre entrouverte) est évidemment plus mauvais et ce type d'appareil n'offre que des performances médiocres.These room air-water conditioners or more rarely water-water or even air-air are generally used - directly in tap water for water-air or water-water devices from a kitchen tap or bathroom and rejection most often in
WC, sink, sink, etc ... These installations require flexible connections which cross the premises with all the drawbacks that this entails (size, condensation, aesthetics ...) - by opening a window to evacuate, outside, calories from air-to-air conditioners. The overall performance (half-opened window) is obviously worse and this type of device offers only poor performance.

- sur des boucles d'eau rafraîchies par des aeroréfrigérants et réchauffées par des générateurs quelconques pour les installations réversibles. Dans ce cas, la T"C de la boucle reste trop élevée (autour de 40 C) ce qui générerait de la chaleur sur tous les radiateurs de l'installation, il est donc nécessaire soit d'isoler les tuyauteries, soit de les faire cheminer en dehors du volume chauffé, ce qui n'est pas le cas des installations existantes.- on loops of water cooled by air coolers and heated by any generators for reversible installations. In this case, the T "C of the loop remains too high (around 40 C) which would generate heat on all the radiators of the installation, it is therefore necessary either to insulate the pipes, or to make them route outside the heated space, which is not the case with existing installations.

- avec de l'eau de forage selon le même principe que celui de l'invention mais sur un réseau distinct.- with drilling water according to the same principle as that of the invention but on a separate network.

L'invention consiste à créer un réseau mixte
ETE/HIVER à partir des conduites existantes et d'installer
Dans la version l : 1")1 échangeur sur le réseau existant (repère 4 des schémas l et 2) destiné à récupérer les frigories ou les calories nécessaires aux climatiseurs individuels.The invention consists in creating a mixed network
SUMMER / WINTER from existing pipes and install
In version l: 1 ") 1 exchanger on the existing network (item 4 of diagrams l and 2) intended to recover the frigories or calories necessary for room air conditioners.

2") de raccorder le réseau primaire de l'échangeur directement sur le réseau arrivée eau de ville juste après compteur et, par conséquent, de faire passer la totalité du débit E.V dans le primaire échangeur. 2 ") to connect the primary exchanger network directly to the mains water supply network just after the meter and, therefore, to pass the entire E.V flow through the primary exchanger.

3 ) d'installer en lieu et place des bouchons de radiateurs existants, des vannes afin de raccorder par liaisons souples les climatiseurs individuels (repère 6). Cette version de l'installation sous entend que le débit d'eau disponible en ce point permet une irrigation du condenseur du climatiseur avec un AT C de 5 à 6". Au-delà, le radiateur chaufferait le local à traiter et annulerait, de ce fait, l'action du climatiseur. 3) to install instead of existing radiator caps, valves in order to connect flexible air conditioning to the individual air conditioners (item 6). This version of the installation implies that the water flow available at this point allows irrigation of the air conditioner condenser with an AT C of 5 to 6 ". Beyond this, the radiator would heat the room to be treated and cancel, this fact, the action of the air conditioner.

4 ) d'installer 2 tés et 2 vannes (repère 7) en amont au radiateur de la pièce à traiter lorsque le débit d'eau a été calculé en chauffage avec un AT C supérieur à 6"C.  4) install 2 tees and 2 valves (item 7) upstream of the radiator of the room to be treated when the water flow rate has been calculated for heating with an AT C greater than 6 "C.

5 ) d'installer une vannes 3 voies (repère 5) en sortie primaire échangeur permettant de réguler l'arrivée E.V en fonction de la T"C de la boucle, lorsqu'il n'y a pas de soutirage. 5) to install a 3-way valve (item 5) at the primary exchanger outlet allowing the E.V. inlet to be regulated according to the T "C of the loop, when there is no withdrawal.

Dans la version 2 l ) Dito version 1 2") Dito version 1 3 ) Dito version l 4 ) Dito version l 5 ) de réaliser un forage aquifère (repère 5 schéma 2) dont la pompe est commandée par l'information de T"C du départ ou du retour boucle.In version 2 l) Dito version 1 2 ") Dito version 1 3) Dito version l 4) Dito version l 5) to carry out an aquifer drilling (reference 5 diagram 2) whose pump is controlled by the information of T" C of the start or return loop.

6 ) d'installer un ballon tampon en un point quelconque du réseau pour éviter les démarrages fréquents de la pompe de puits (repère 8 schéma 2). 6) install a buffer tank at any point on the network to avoid frequent starts of the well pump (item 8 diagram 2).

Caractéristiques communes aux 2 versions en fonctionnement climatisation : - la chaudière (repère 1) est à l'arrêt. Characteristics common to the 2 versions in air conditioning operation: - the boiler (item 1) is stopped.

- la ou les vannes de régulation (l'installation peut en comporter plusieurs) sont positionnées de façon à ne pas irriguer la chaudière (repère 2 des schémas).- the control valve (s) (the installation may include several) are positioned so as not to irrigate the boiler (item 2 of the diagrams).

- la pompe (repère 3) est en marche.- the pump (item 3) is running.

- l'échangeur est irrigué soit par de l'eau de ville, soit par de l'eau de forage.- the exchanger is irrigated either by city water or by drilling water.

- le réseau alimentant les radiateurs existants fonctionne a: * 20"C T"C départ, + 25"C TOC retour, afin de ne pas réchauffer les locaux climatisés ou non.- the network supplying the existing radiators operates at: * 20 "C T" C outgoing, + 25 "C TOC return, so as not to heat the air-conditioned premises or not.

- l'eau primaire (E.V ou puits) rentre dans l'échangeur à 13/15"C. Elle ressort à 23"C environ.- the primary water (E.V or well) enters the exchanger at 13/15 "C. It comes out at around 23" C.

- L'installation utilise le débit eau prévu pour le chauffage avec un AT C d'origine de l'ordre de 20"C en général. L'installation climatisation fonctionne avec un AT C condenseur de 5"C à 7"C, ce qui limite à 20/25 X environ les possibilités de climatisation de l'immeuble.- The installation uses the water flow rate intended for heating with an original AT C of around 20 "C in general. The air conditioning installation works with a condenser AT C from 5" C to 7 "C, this which limits the building's air conditioning possibilities to around 20/25 X approximately.

- le fonctionnement est du type alternatif. Les pièces de nuit ou de jour ne sont pas traitées simultanément.- the operation is of the alternative type. Night or day rooms are not processed simultaneously.

- les besoins en eau de ville journaliers par individu sont de 150 litres/jour, ce qui représente pour les T"C annoncées une récupération possible de 1,4 à 2 kWh/jour/occupant pour l'ensemble de l'immeuble, y compris ceux qui n'utilisent pas le système de climatisation. Non compris l'arrosage des espaces verts et besoins annexes éventuels.- the daily city water needs per individual are 150 liters / day, which represents for the T "Cs announced a possible recovery of 1.4 to 2 kWh / day / occupant for the whole building, including including those who do not use the air conditioning system Not including watering green spaces and any additional needs.

- l'eau de ville est utilisée 2 fois (version 1 uniquement) à des fins thermiques et domestiques sans que cela devienne de l'eau tiède (T"C de distribution maximum 23"C). - city water is used twice (version 1 only) for thermal and domestic purposes without it becoming lukewarm water (T "C maximum distribution 23" C).

- avec des climatiseurs réversibles, l'installation peut être utilisée en chauffage d'appoint ou en secours.- with reversible air conditioners, the installation can be used as backup heating or as backup.

- le forage dans la version 2 peut également être utilisé pour les besoins d'arrosage ou d'eau brute éventuel. - the borehole in version 2 can also be used for irrigation or possible raw water needs.
