DISPOSITIF DE CONTROLE D'UNE INSTALLATION DE CHAUFFAGE OU DEVICE FOR CONTROLLING A HEATING PLANT OR
DE CLIMATISATION D'UN LOCAL OF AIR CONDITIONING OF A LOCAL
DOMAINE DE L'INVENTION FIELD OF THE INVENTION
La présente invention concerne les systèmes de régulation de la température, et plus particulièrement les systèmes de climatisation, de climatisation réversible ou de chauffage et leurs moyens de contrôle. The present invention relates to temperature control systems, and more particularly the air conditioning, reversible air conditioning or heating systems and their control means.
Particulièrement, la présente invention est utile pour contrôler la température dans une ou plusieurs pièces d'un bâtiment comprenant une multitude de pièces tel qu'un immeuble ou encore un hôtel. In particular, the present invention is useful for controlling the temperature in one or more rooms of a building comprising a multitude of rooms such as a building or a hotel.
ARRIERE-PLAN TECHNIQUE TECHNICAL BACKGROUND
Les systèmes de climatisation ou de chauffage existants sont généralement constitués d'une unité ventilateur / convecteur ou convecteur seul, qui est alimentée par le réseau. Elles sont commandées par un thermostat pouvant être actionné par l'utilisateur qui en détermine la consigne (froid, chaud, température, vitesse de ventilation etc .). Dans des bâtiments regroupant plusieurs pièces, tels qu'un hôtel où les résidents changent fréquemment, ces installations nécessitent d'être contrôlées. La température des ventilo-convecteurs est ainsi prédéfinie et l'utilisateur vient modifier la température s'il le souhaite lorsqu'il prend possession des lieux ou au cours de son séjour.  Existing air conditioning or heating systems typically consist of a fan / convector or convector unit alone, which is powered by the network. They are controlled by a thermostat that can be operated by the user who determines the setpoint (cold, hot, temperature, ventilation speed, etc.). In multi-room buildings, such as a hotel where residents change frequently, these facilities need to be controlled. The temperature of the fan convectors is thus predefined and the user changes the temperature if he wishes when he takes possession of the premises or during his stay.
La demande européenne EP-A-2 088 383 décrit un exemple d'installation conventionnelle dans un hôtel comprenant plusieurs pièces à climatiser. L'installation comprend une ou plusieurs automates primaires situées dans les pièces à climatiser et un automate central (ou maître) distant. L'automate central permet de contrôler à distance chacun des automates locaux et de contrôler ainsi centralement des ventilo-convecteurs individuels ou des groupes de ventilo-convecteurs.  European application EP-A-2 088 383 describes an example of a conventional installation in a hotel comprising several rooms to be air-conditioned. The installation includes one or more primary PLCs located in the rooms to be conditioned and a central controller (or master) remote. The central controller allows remote control of each of the local PLCs and thus centrally control individual fan coil units or fan coil units.
Typiquement, ce type d'installation contrôlée (ou Gestion Techniques Contrôlées) est fourni par un même installateur (solutions dites propriétaires). Ainsi, les différentes unités de l'installation communiquent entre elles dans un même langage propriétaire ou via des cartes de communication avec un protocole commun type KNX, habituellement à l'aide de cartes de communication électroniques. La température mesurée et les autres informations du thermostat sont alors rendues exclusives lorsqu'elles sont reprises par les différentes unités de l'installation. En outre ces systèmes de contrôle gèrent également le fonctionnement du convecteur lui-même. L'installation devient alors difficilement modifiable et/ou évoluable sans utiliser des matériels communicants le plus souvent de même marque. Typically, this type of controlled installation (or Controlled Technical Management) is provided by the same installer (so-called proprietary solutions). Thus, the different units of the installation communicate with each other in the same proprietary language or via communication cards with a common KNX protocol, usually using electronic communication cards. The measured temperature and other information of the thermostat are then made exclusive when they are taken up by the different units of the installation. In addition, these control systems also manage the operation of the convector itself. The installation then becomes difficult to modify and / or evolve without using communicating materials most often of the same brand.
De fait, il est fréquent que ces dispositifs électroniques tombent en panne tant au niveau de l'unité centrale que des automates locaux. Cela affecte le dispositif de régulation et il devient alors impossible de maintenir le contrôle de la température dans les pièces, qui ne sont plus reliées ou bien dans les pièces dans lesquels les automates locaux sont défectueux, voire d'utiliser le convecteur/climatiseur lui-même. D'autre part, compte tenu de la complexité des systèmes électroniques de communication et de la disponibilité des solutions propriétaires, il est souvent nécessaire de patienter de longues semaines avant de recevoir un élément de remplacement, de pouvoir procéder aux réparations ou bien encore de disposer des évolutions ou programmes. Dans ce type de système, les coûts et délais sont imposés par le fabricant et/ou l'installateur, seuls susceptibles d'intervenir sur leur solution propriétaire. Le même type de contrainte apparaît avec des dispositifs de contrôle standards.  In fact, it is common for these electronic devices to fail both at the level of the central unit and local controllers. This affects the control device and it becomes impossible to maintain control of the temperature in the rooms, which are no longer connected or in the rooms in which local controllers are defective, or even to use the convector / air conditioner itself. even. On the other hand, given the complexity of electronic communication systems and the availability of proprietary solutions, it is often necessary to wait for long weeks before receiving a replacement item, to be able to carry out repairs or to have developments or programs. In this type of system, the costs and deadlines are imposed by the manufacturer and / or the installer, the only ones likely to intervene on their proprietary solution. The same type of constraint appears with standard control devices.
En outre, il apparaît que ces systèmes de contrôle centralisés ne sont pas satisfaisant puisqu'ils font communément varier les températures par anticipation en fonction de l'occupation prévisible des locaux mais ne permettent en réalité pas d'adapter le contrôle au planning réel de l'occupation des pièces. Ainsi, de nombreux ajustements supplémentaires de température supplémentaires restent nécessaires. RESUME DE L'INVENTION  In addition, it appears that these centralized control systems are not satisfactory since they commonly vary the temperatures in anticipation according to the foreseeable occupancy of the premises but do not actually allow to adapt the control to the actual planning of the premises. occupation of the rooms. Thus, many additional additional temperature adjustments are necessary. SUMMARY OF THE INVENTION

Les résidents restent alors maîtres chez eux et gardent la main sur le thermostat et donc sur le système de régulation. D'autre part, les dispositifs selon l'invention s'adaptent en parallèle sur des systèmes de climatisation/chauffage primaires, sans qu'il soit nécessaire de les insérer dans la chaîne de commande ou de régulation du système de contrôle existant, ni modifier l'installation déjà en place ou d'engendrer des travaux supplémentaires.

Elle concerne également les installations agissant sur une ventilation qui propulse l'air au travers de la batterie pour chauffer ou refroidir une pièce. Typiquement, des exemples d'installations compatibles avec la présente invention sont les radiateurs électriques, les VMC double flux, les plafonds rafraîchissants, les plafonds chauffants ou bien les climatisations. De préférence la présente invention s'applique à des installations de climatisation de climatisation réversible, ou bien de chauffage. The present invention relates to an installation for regulating the temperature of a room. It applies to any type of heating or air conditioning system using air or water as heat transfer fluid to heat or cool a room. It relates to conventional radiators heating parts by convection or radiation without the provision of a fan and with a control acting only on a solenoid valve to let the heat transfer fluid through the battery. It also relates to facilities acting on a ventilation that propels air through the battery to heat or cool a room. Typically, examples of installations compatible with the The present invention is electric heaters, dual flow VMCs, cooling ceilings, heating ceilings or air conditioning. Preferably, the present invention applies to reversible air conditioning or heating air conditioning installations.
La présente invention est utilisable pour une pièce ou un groupe de pièces destinés au même type d'exploitation, tels que des bureaux, salles de réunions, ou bien destinés à accueillir une même catégorie de résidents (collaborateurs, familles, clients portés sur la réclamation). De façon préférée, la présente invention est particulièrement utile dans des hôtels, pour lesquels les systèmes de régulation de la température sont essentiels pour le confort des résidents et très souvent onéreux.  The present invention is usable for a room or group of rooms intended for the same type of operation, such as offices, meeting rooms, or intended to accommodate the same category of residents (employees, families, customers on the claim) ). Preferably, the present invention is particularly useful in hotels, where the temperature control systems are essential for the comfort of residents and very often expensive.
Les systèmes de climatisation réversibles considérés dans la présente invention, sans être limité portent sur les systèmes reliés à des réseaux d'eau à deux ou quatre tuyaux. Typiquement un réseau à deux tuyaux permet d'acheminer soit de l'eau froide soit de l'eau chaude tandis qu'un réseau à quatre tuyaux permet de faire passer à travers une batterie double soit de l'eau dans la batterie chaude soit de l'eau dans la batterie froide du ventilo-convecteur.  The reversible air conditioning systems considered in the present invention, without being limited, relate to systems connected to water networks with two or four pipes. Typically a two-pipe network can convey either cold water or hot water while a four-pipe network can pass through a dual battery is water in the hot battery or the water in the cold battery of the fan coil.
Dans le cadre de la présente invention, le terme de « ventilo- convecteur » se réfère à l'élément de l'installation de climatisation ou de chauffage capable de propulser de l'air chauffé ou refroidi dans une pièce à tempérer. Il s'agit d'un élément terminal dans l'installation de la climatisation réversible.  In the context of the present invention, the term "fan coil" refers to the element of the air conditioning or heating system capable of propelling heated or cooled air into a room to be tempered. This is a terminal element in the installation of reversible air conditioning.
Dans le cadre de la présente invention, le terme de « thermostat » s'entend d'un élément de l'installation, typiquement un boîtier de commande électronique ou électromécanique permettant à l'utilisateur de forcer la création de chaleur ou de froid dans la pièce. De façon avantageuse, le thermostat comprend un écran digital indiquant diverses informations telles que la température de la pièce, la date, l'heure, la vitesse de ventilation etc .. De façon avantageuse, le thermostat permet à l'utilisateur de rentrer directement la température qu'il souhaite dans la pièce, à l'aide d'un bouton molette ou digitalement.  In the context of the present invention, the term "thermostat" refers to an element of the installation, typically an electronic or electromechanical control unit allowing the user to force the creation of heat or cold in the room. Advantageously, the thermostat comprises a digital screen indicating various information such as room temperature, date, time, ventilation speed, etc. Advantageously, the thermostat allows the user to enter the room directly. temperature it wants in the room, using a knob or digitally.
Dans le cadre de la présente invention, un automate local, c'est à dire qui se situe dans la pièce à tempérer, est ajouté à un système de régulation existant. Il est ajouté en place du système de contrôle initial de l'installation. Elle On entend par « initial », le système de contrôle initialement adapté à l'installation. Typiquement, le système de contrôle initial est du type Gestion Techniques Centralisées et se constitue d'éléments communiquant entre eux par le biais de cartes de communication de systèmes propriétaires, c'est-à- dire communiquant dans un langage qui est propre au fabricant de l'installation. La plupart des GTC qui sont installées se contentent d'imposer une température dans une pièce. Certaines plus complexes multiplient les capteurs, par exemple au niveau des fenêtres pour de couper la climatisation lorsqu'une la pièce est ouverte. Ce type de système primaire augmente donc le risque de panne ou de disfonctionnement. Ils sont donc très difficiles à gérer au quotidien. In the context of the present invention, a local controller, ie which is located in the room to be tempered, is added to an existing control system. It is added in place of the initial control system of the installation. It means "initial", the control system initially adapted to the installation. Typically, the initial control system is of the Centralized Technical Management type and consists of elements communicating with each other through communication cards of proprietary systems, ie communicating in a language that is specific to the manufacturer of the installation. Most GTCs that are installed simply impose a temperature in a room. Some more complex multiply sensors, for example at the windows to cut air conditioning when a room is open. This type of primary system therefore increases the risk of breakdown or malfunction. They are very difficult to manage on a daily basis.
Selon la présente invention, l'automate local est relié à une sonde autonome, c'est-à-dire distincte de la sonde comprise dans le thermostat du système de régulation de la température pour offrir une information fiable à l'automate local. La sonde autonome est alors disposée dans la même pièce ou espace à ventiler que le thermostat. Les sondes appropriées sont celles généralement connues de l'homme du métier et conventionnellement utilisées dans le domaine. Typiquement, la sonde peut être fixée à l'emplacement du thermostat existant ou dans celui-ci de façon à minimiser les travaux d'installation. La sonde peut avantageusement être fixée au thermostat existant à l'aide d'un cavalier et un connecteur deux fils. De façon à limiter d'avantage les travaux, le fil servant à relier la sonde autonome à l'automate local peut également venir se loger dans la gaine ou câble du thermostat initialement posés pour l'installation de régulation initiale.  According to the present invention, the local PLC is connected to an autonomous probe, that is to say separate from the probe included in the thermostat of the temperature control system to provide reliable information to the local controller. The autonomous probe is then placed in the same room or space to ventilate as the thermostat. Suitable probes are those generally known to those skilled in the art and conventionally used in the field. Typically, the probe can be attached to the location of the existing thermostat or in it to minimize installation work. The probe can advantageously be attached to the existing thermostat using a jumper and a two-wire connector. In order to limit further work, the wire used to connect the autonomous probe to the local controller can also be housed in the sheath or cable of the thermostat initially installed for the initial control installation.
L'ensemble automate local/sonde, constitue un dispositif de régulation redondant, c'est-à-dire qui est installé en parallèle d'un premier dispositif de régulation. Le terme implique que les deux dispositifs sont installés en parallèles et peuvent fonctionner alternativement l'un avec l'autre. Les figures 1 e 2 schématisent un dispositif selon l'art antérieur et un dispositif selon la présente invention dans lequel on observe que l'automate local et la sonde sont disposés et reliés en parallèle du système existant.  The local controller / probe assembly constitutes a redundant control device, that is to say which is installed in parallel with a first control device. The term implies that the two devices are installed in parallel and can work alternately with each other. FIGS. 1 and 2 schematize a device according to the prior art and a device according to the present invention in which it is observed that the local automaton and the probe are arranged and connected in parallel with the existing system.
En cas de panne, la présente invention correspond à un système robuste, simple et économiquement avantageux qui permet de surmonter la panne et de continuer à climatiser ou chauffer la pièce malgré la panne du système primaire de contrôle. Cela devient particulièrement avantageux dans les immeubles tels que les hôtels dans lesquels il est coûteux de ne pas pouvoir utiliser une pièce mal tempérée et entraine des plaintes de clients. Typiquement, les dispositifs selon l'invention permettent de réduire de 70 à 80% les coûts de maintenance d'une installation contrôlée conventionnelle. Elle est également, plus économique à l'installation avec une réduction des coûts de l'ordre de 20 à 30% par rapport à une installation contrôlée conventionnelle. In case of failure, the present invention corresponds to a robust, simple and economically advantageous system that overcomes the failure and continue to cool or heat the room despite the failure of the primary control system. This becomes particularly advantageous in buildings such as hotels where it is expensive to not be able to use a poorly tempered room and causes complaints from customers. Typically, the devices according to the invention can reduce from 70 to 80% the maintenance costs of a conventional controlled installation. It is also more economical to install with a reduction of costs of the order of 20 to 30% compared to a conventional controlled installation.
L'automate local est susceptible d'être relié à un système de contrôle parallèle au premier système, lequel peut éventuellement être déposé lors de l'installation des dispositifs de l'invention. De façon avantageuse, plusieurs automates et donc dispositifs peuvent être reliés ou groupés sur des relais qui sont eux-mêmes connectés au système de contrôle.  The local PLC is likely to be connected to a control system parallel to the first system, which may possibly be deposited during the installation of the devices of the invention. Advantageously, several automata and therefore devices can be connected or grouped on relays which are themselves connected to the control system.
A l'aide de ce deuxième système de contrôle, l'automate peut être activé ou désactivé à distance pour prendre le contrôle ou bien au contraire laisser possibilité au résident de contrôler la température localement. Il est également envisageable de permettre à l'automate local de désactiver le système de contrôle redondant manuellement par exemple à l'aide d'un mécanisme mécanique.  Using this second control system, the PLC can be activated or deactivated remotely to take control or on the contrary allow the resident to control the temperature locally. It is also conceivable to allow the local controller to disable the redundant control system manually, for example using a mechanical mechanism.
De façon avantageuse, le système de contrôle redondant est géré à partir d'un automate serveur. L'automate serveur est alors connecté à internet et envoie des instructions par le réseau, à distance des automates locaux. L'automate serveur est disponible à partir de n'importe quel terminal « administrateur » connecté à internet, par exemple à l'aide d'une connexion sécurisée, De cette manière, le gérant ou les techniciens d'un bâtiment ou d'un hôtel peuvent contrôler le système via leur téléphone portable en toute liberté de mouvement. Ce système de gestion permet d'outrepasser si besoin le système de régularisation primaire d'une installation tout en gardant la main sur les dispositifs à distance. Dans le cadre d'un hôtel, un exemple de terminal peut être l'ordinateur de la réception, où sont généralement centralisées les différentes informations des chambres.  Advantageously, the redundant control system is managed from a server controller. The server PLC is then connected to the Internet and sends instructions via the network, away from the local PLCs. The server PLC is available from any "administrator" terminal connected to the internet, for example by means of a secure connection. In this way, the manager or the technicians of a building or a hotel can control the system via their mobile phone with complete freedom of movement. This management system makes it possible to override, if necessary, the primary regulation system of an installation while keeping control of the remote devices. As part of a hotel, an example of a terminal may be the reception computer, where the room information is usually centralized.
Typiquement, un logiciel de gestion est installé sur un serveur distant, c'est-à-dire situé en dehors des murs du bâtiment. L'utilisateur y accède via un terminal connecté à internet, par exemple à l'aide d'une interface sécurisée pour contrôler les différents dispositifs reliés. Le logiciel de gestion peut également être disponible via une interface web. Ainsi, les différentes mises à jour et interventions sur le logiciel de contrôle peuvent se faire à distance et en une seule fois sans qu'il soit nécessaire de se déplacer sur chacun des sites utilisant le système, comme c'est actuellement le cas pour les solutions existantes. Un exemple d'interface logiciel est donné dans la figure 3.  Typically, a management software is installed on a remote server, that is to say located outside the walls of the building. The user accesses it via a terminal connected to the internet, for example using a secure interface to control the various connected devices. The management software can also be available via a web interface. Thus, the various updates and interventions on the control software can be done remotely and in one go without the need to move to each of the sites using the system, as is currently the case for existing solutions. An example of a software interface is given in Figure 3.
Des systèmes de domotique utilisables via le réseau internet, notamment par wifi ou par le réseau téléphonique, sont connus en tant que tels et sont appliqués dans la présente invention au système de climatisation, en particulier d'un immeuble ou d'un hôtel. Home automation systems that can be used via the Internet, in particular via wifi or the telephone network, are known as Such and are applied in the present invention to the air conditioning system, in particular a building or a hotel.
Il devient alors possible de contrôler chaque dispositif individuellement, et donc de contrôler chaque pièce d'un bâtiment. Il est également possible de contrôler tout un groupe de pièces à la fois, par exemple celles qui dans un même bâtiment sont extérieures et ont la même orientation. Il est en effet utile de pouvoir agir sur l'ensemble des pièces qui sont confrontées aux mêmes conditions d'ensoleillement, de froid etc .. De façon avantageuse, il est également possible de forcer le système de contrôle redondant dans des plages horaires prédéfinies, notamment pour harmoniser les températures et optimiser le gain d'énergie.  It then becomes possible to control each device individually, and thus to control each room of a building. It is also possible to control a whole group of rooms at a time, for example those which in the same building are exterior and have the same orientation. It is indeed useful to be able to act on all the parts that face the same conditions of sunshine, cold etc. Advantageously, it is also possible to force the redundant control system within predefined time periods, in particular to harmonize the temperatures and optimize the energy gain.
Typiquement, les plages horaires suivantes peuvent être envisagées avec l'objet de la présente invention. Celles-ci correspondent aux plages horaires dans lesquelles les clients sont physiquement présents dans les chambres.  Typically, the following time slots can be envisaged with the object of the present invention. These correspond to the time slots in which guests are physically present in the rooms.

La figure 4 illustre un exemple de systèmes selon l'invention, dans lequel l'automate local de chacune des pièces d'un même groupe de pièces situées sur une même façade, sont reliées entre elles à une connexion ethernet/internet. Les autres pièces du bâtiment ne sont pas représentées sur la figure. Le logiciel de gestion, installé sur un serveur distant est alors accessible via un terminal du bâtiment, tel que l'ordinateur de la réception. FIG. 4 illustrates an example of systems according to the invention, in which the local automaton of each of the parts of the same group of parts located on the same facade, are interconnected to an ethernet / internet connection. The other parts of the building are not shown in the figure. The management software installed on a remote server is then accessible via a terminal of the building, such as the computer of the reception.
