Abstract

The method involves remotely controlling a power supply and an energy source e.g. gas or fuel oil, with respect to needs of a heating system of a room to be heated by deactivating and activating an electrical heat pump (10) based on needs of the system during winter season, to generate peaks of electrical consumption. The heat pump is deactivated by remotely controlling regulation of a control device of heating installation by a radio or wired Ethernetline (24). An independent claim is also included for a device for control and power disconnection of an electrical network remotely from a mixed energy heat unit, comprising an electrical heat pump.

Description

L'invention concerne un procédé et un dispositif de contrôle et de délestage du réseau électrique à distance d'une unité thermique à énergie mixte et son application à la facturation de la consommation par le fournisseur d'énergie. The invention relates to a method and a device for controlling and offloading the remote electricity network of a mixed energy thermal unit and its application to the billing of consumption by the energy supplier.

On connaît déjà différents moyens permettant d'optimiser, au niveau du consommateur, le coût de l'énergie qui lui est délivré pour le conditionnement d'air de locaux et de bâtiments faisant appel au gaz selon un cycle thermodynamique à gaz frigorigène, dont la fonction chauffage est assurée par un échangeur gaz et la fonction réfrigération par un groupe réfrigérant pour sélection automatique de la forme d'énergie la plus appropriée en fonction de son coût. Un tel dispositif est décrit dans la demande de brevet européen n° 08006964.4/1980794, avec lequel l'optimisation est obtenue par l'intermédiaire d'une batterie d'échange comportant un clapet de by-pass évitant à l'air de le traverser par temps froid, lorsque l'appareil fonctionne au gaz. Le fonctionnement du dispositif étant contrôlé par un boîtier électronique, asservi au coût des formes d'énergie utilisées. Various means are already known for optimizing, at the level of the consumer, the cost of the energy which is delivered to him for the air conditioning of premises and buildings using gas according to a thermodynamic cycle with a refrigerant gas, whose Heating function is provided by a gas exchanger and the refrigeration function by a refrigerant group for automatic selection of the most appropriate form of energy according to its cost. Such a device is described in the European patent application No. 08006964.4 / 1980794, with which the optimization is obtained via an exchange battery comprising a bypass valve avoiding air to cross it. in cold weather, when the appliance is running on gas. The operation of the device being controlled by an electronic box, subject to the cost of the forms of energy used.

Par contre, rien n'a été fait jusqu'alors au niveau du concessionnaire électrique pour commercialiser une énergie thermique plutôt qu'une énergie électrique, par délestage du réseau par mise hors service des pompes à chaleur au profit d'une source d'énergie secondaire telle que le gaz ou le fioul. On the other hand, nothing has been done so far at the level of the electric concessionaire to commercialize a thermal energy rather than an electric power, by offloading the network by putting out of service of the heat pumps in favor of a source of energy. secondary such as gas or fuel oil.

La présente invention a pour but de remédier à cet inconvénient. Cette invention, telle qu'elle se caractérise, résout le problème consistant à définir un procédé et à créer un dispositif permettant sa mise en oeuvre à distance, en vue d'obtenir une mise hors service des pompes à chaleur au profit d'une autre source d'énergie, afin de ne pas avoir à utiliser des centrales thermiques pour palier les carences des centrales nucléaires en hiver lorsque la demande d'électricité est trop importante, ainsi que pour limiter la puissance transportée sur les lignes de distribution électrique. The present invention aims to overcome this disadvantage. This invention, as it is characterized, solves the problem of defining a method and creating a device for its remote implementation, to obtain a shutdown heat pumps for the benefit of another energy source, so as not to have to use thermal power plants to overcome the deficiencies of nuclear power plants in winter when the demand for electricity is too great, as well as to limit the power transported on power distribution lines.

Le procédé de contrôle et de délestage du réseau électrique à distance au profit d'une autre source d'énergie lors des surcharges du réseau résultant de conditions climatiques hivernales rigoureuses, concernant les unités thermiques à énergie mixte comportant une pompe à chaleur électrique et une chaudière à gaz ou au fioul, se caractérise, selon l'invention, en ce qu'il consiste à contrôler à distance une alimentation électrique et une source énergétique secondaire par rapport au besoin du réseau de chauffage du local à chauffer par mise hors service de la pompe à chaleur au profit de la chaudière alors en service, en fonction du besoin du réseau de chauffage lors de la période hivernale, générant des pics de consommation électrique. The method of controlling and releasing the remote electricity network for the benefit of another source of energy during network overloads resulting from severe winter weather conditions, with regard to the mixed-energy thermal units comprising an electric heat pump and a boiler gas or oil, is characterized, according to the invention, in that it consists in remotely controlling a power supply and a secondary energy source with respect to the need for the heating network of the room to be heated by putting out of service the heat pump in favor of the boiler then in service, according to the need of the heating network during the winter period, generating peaks of electricity consumption.

Ce procédé de contrôle et de délestage est appliqué par pilotage à distance de la régulation du dispositif de contrôle de l'installation ; ce pilotage à distance pouvant être effectué par ligne Ethernet, ou filaire, ou par radio. Le dispositif de mise en oeuvre du procédé selon l'invention se caractérise en ce qu'il est constitué d'une armoire de contrôle et de régulation, à régulateur pilotable à distance en fonction des besoins thermiques du réseau de chauffage. 20 Le dispositif est asservi à un moyen de mesure de la température de la source (eau ou air) où sont puisées les calories par la pompe à chaleur, associé à un moyen de contrôle du fonctionnement de ladite pompe selon les besoins thermiques de l'installation de chauffage, de façon que, lorsque lesdits besoins 25 sont supérieurs à ceux dissipés par celle-ci, la chaudière soit mise en service, et que, lorsque la température de ladite source où sont puisées les calories par la pompe est trop basse, celle-ci soit mise hors service, tout en conservant la chaudière en service ; la mise hors service de la pompe à chaleur et la mise ou le maintien de la chaudière en service pouvant être obtenus à distance par le 30 concessionnaire électrique, par action directe sur le régulateur, pour faire face15 à un pic de demande de son réseau, quelles que soient alors les conditions de fonctionnement de l'installation. This control and load shedding method is applied by remotely controlling the regulation of the control device of the installation; this remote control can be performed by Ethernet, or wired, or by radio. The device for implementing the method according to the invention is characterized in that it consists of a control and regulation cabinet, controllable remote controller according to the thermal needs of the heating network. The device is slaved to a means for measuring the temperature of the source (water or air) where the heat pump is pulsed, associated with a means for controlling the operation of said pump according to the thermal needs of the pump. heating system, so that when said needs are greater than those dissipated by it, the boiler is put into operation, and when the temperature of said source where the calories are drawn by the pump is too low, this one is put out of service, while keeping the boiler in service; the putting out of service of the heat pump and the putting or maintaining of the boiler in operation which can be obtained remotely by the electric dealer, by acting directly on the regulator, to cope with a peak demand of his network, whatever the operating conditions of the installation.

Ce dispositif permet la facturation, par le fournisseur d'énergie, non pas de l'électricité ou de l'énergie secondaire, mais de l'énergie sortant de l'unité. Le consommateur a donc à payer un prix fixe de l'énergie, sans avoir à tenir compte de l'énergie utilisée pour la transformer en chauffage. This device allows the billing, by the energy supplier, not electricity or secondary energy, but energy coming out of the unit. The consumer therefore has to pay a fixed price for energy, without having to take into account the energy used to transform it into heating.

Les avantages obtenus, grâce à cette invention, consistent, pour l'essentiel, en ce qu'elle permet de commercialiser une énergie thermique et non une source d'énergie (électrique et secondaire), d'optimiser le coût de l'énergie délivrée grâce au mixte pompe à chaleur et énergie secondaire et en ce que, grâce au délestage électrique, elle permet de réduire les coûts d'investissement en centrale électrique d'appoint et en ligne de distribution du concessionnaire électrique. The advantages obtained, thanks to this invention, consist, essentially, in that it makes it possible to commercialize a thermal energy and not a source of energy (electrical and secondary), to optimize the cost of the energy delivered. thanks to the combined heat pump and secondary energy and in that, thanks to the electric load shedding, it makes it possible to reduce the costs of investment in electric power station and in line of distribution of the electric dealer.

D'autres caractéristiques et avantages apparaîtront dans la description qui va suivre d'une unité thermique à énergie mixte et à délestage électrique piloté à distance, réalisée selon l'invention, donnée à titre d'exemple non limitatif, au regard des dessins annexés, représentant : Other features and advantages will appear in the following description of a mixed-energy thermal unit and remote controlled electric shedding, carried out according to the invention, given by way of non-limiting example, with reference to the accompanying drawings, representative:

- figure 1 une vue schématique de l'ensemble de l'installation, - Figure 1 a schematic view of the entire installation,

- figure 2 une vue schématique de l'installation reliée au réseau d'électricité et 25 à un bâtiment à chauffer. - Figure 2 a schematic view of the installation connected to the electricity network and 25 to a building to be heated.

Les figures représentent une unité thermique 1 comprenant une pompe à chaleur 10 comportant un premier échangeur 11 puisant des calories dans l'air soufflé par un ventilateur 12, relié à un second échangeur 13, à l'aval par 30 l'intermédiaire d'un compresseur 14 et, à l'amont, par un détendeur 15 ; le second échangeur 13 étant relié lui-même à la tuyauterie de retour 16 du circuit de chauffage et au circuit d'alimentation 17 de la chaudière 18, dont le brûleur 19 est muni d'un régulateur de débit 191, contrôlé par le régulateur de l'armoire de contrôle et de régulation 20, ainsi que le compresseur 14, respectivement par les liaisons électriques 21 et 22 ; l'armoire de contrôle et de régulation 20 étant reliée à une alimentation électrique 23 par le réseau 3 et à la ligne de commande à distance 24 ; l'unité thermique 1 étant reliée électriquement par l'intermédiaire de son armoire de contrôle et de régulation 20 au réseau électrique 3, lui-même relié à une centrale nucléaire 4 et à une centrale d'appoint 5, avec contrôle à distance par une ligne Ethernet 24. The figures show a heat unit 1 comprising a heat pump 10 comprising a first exchanger 11 drawing calories in the air blown by a fan 12, connected to a second exchanger 13, downstream via a compressor 14 and, upstream, by a pressure regulator 15; the second exchanger 13 being itself connected to the return pipe 16 of the heating circuit and to the supply circuit 17 of the boiler 18, the burner 19 of which is provided with a flow regulator 191, controlled by the regulator of the control and regulation cabinet 20, as well as the compressor 14, respectively by the electrical connections 21 and 22; the control and regulation cabinet 20 being connected to a power supply 23 via the network 3 and to the remote control line 24; the thermal unit 1 being electrically connected via its control and regulation cabinet 20 to the electrical network 3, itself connected to a nuclear power plant 4 and a booster unit 5, with remote control by a Ethernet line 24.

En examinant plus en détail la figure 1, on remarque que, en fonctionnement normal, le dispositif fournit une énergie thermique grâce à la pompe à chaleur 10, qui puise ses calories dans l'air (dans cet exemple) par l'intermédiaire de son premier échangeur 11 et de son ventilateur 12. By examining in more detail in FIG. 1, it will be noted that, in normal operation, the device supplies thermal energy thanks to the heat pump 10, which draws its calories from the air (in this example) via its first exchanger 11 and its fan 12.

Grâce au principe thermodynamique, l'énergie électrique consommée actionne le compresseur 14, qui augmente, par compression, la température du gaz frigorigène qui va se refroidir ensuite dans le second échangeur 13, en réchauffant l'eau du circuit de chauffage entrant dans celui-ci par la tuyauterie de retour 16 du circuit de chauffage des locaux. Le gaz ainsi refroidi traverse le détendeur 15, qui réduit sa pression et, de ce fait, réduit sa température à une valeur inférieure à celle de la source, ici de l'air, dans laquelle sont puisées les calories par l'intermédiaire du premier échangeur 11. Ce principe aérodynamique permet d'obtenir un coefficient de performance de 2 à 5 (1 kW/h consommé restituant 2 à 5 kW/h). Donc, en fonction des besoins thermiques de l'installation de chauffage, l'armoire de contrôle et de régulation 20 met en service la pompe à chaleur 10 et, si les besoins sont supérieurs à ceux dissipés, met en service, en complément, la chaudière 18 à gaz ou à fioul.30 Lorsque la température de la source est trop basse, le coefficient de performance de la pompe à chaleur 10 diminue et l'armoire de contrôle et de régulation 20 met hors service ladite pompe à chaleur 10, tout en conservant la chaudière 18 en service. Thanks to the thermodynamic principle, the electrical energy consumed actuates the compressor 14, which increases, by compression, the temperature of the refrigerant gas which will then cool in the second heat exchanger 13, by heating the water of the heating circuit entering into the latter. ci by the return pipe 16 of the space heating circuit. The gas thus cooled passes through the regulator 15, which reduces its pressure and, as a result, reduces its temperature to a value lower than that of the source, in this case air, in which the calories are drawn by means of the first exchanger 11. This aerodynamic principle makes it possible to obtain a coefficient of performance of 2 to 5 (1 kW / h consumed restoring 2 to 5 kW / h). Therefore, depending on the thermal requirements of the heating installation, the control and regulation cabinet 20 puts the heat pump 10 into operation and, if the needs are higher than those dissipated, puts into service, in addition, the When the temperature of the source is too low, the coefficient of performance of the heat pump 10 decreases and the control and regulation cabinet 20 deactivates said heat pump 10, while the temperature of the source is too low. keeping the boiler 18 in service.

On comprend que cette recherche de rentabilité de l'installation puisse être temporairement interrompue par intervention directe du concessionnaire électrique sur le régulateur de l'armoire de contrôle et de régulation 20 par l'intermédiaire de la liaison à distance 24 dont il dispose, pour obtenir la mise hors service générale des pompes à chaleur 10 situées dans le secteur qu'il dessert, afin de réduire, par délestage, l'importance de certains pics de consommation, obligeant normalement à mettre en ligne une centrale d'appoint pour faire face à des demandes exceptionnelles se manifestant par temps très froid. It is understood that this search for profitability of the installation can be temporarily interrupted by direct intervention of the electric dealer on the regulator of the control and regulation cabinet 20 via the remote link 24 at his disposal, to obtain the general decommissioning of the heat pumps 10 located in the sector it serves, in order to reduce, by load-shedding, the importance of certain consumption peaks, normally requiring the putting on-line of a booster plant to cope with exceptional demands in very cold weather.
