Description

CONNECTED CLIMATIC SYSTEM

The invention relates to a connected climate system. The invention relates to both climate engineering, business intelligence and inferential computing, commonly referred to as "Big Data", aimed at determining and predicting behaviors from a mass of data, in order to optimize the operation of a system or to analyze its environment.

The term "climate system" refers to all the devices and their implementation processes allowing, at the cost of energy consumption, to modify locally a climatic environment, more particularly, but not exclusively, temperature and hygrometry. Non-exhaustively, the devices involved in a climate system include, heating devices, radiation or convection, reversible air conditioning devices or not, controlled ventilation devices and means for producing hot water.

In all industrialized countries, the energy consumption of climate systems accounts for the largest share of final energy consumption, generally around 40% of the total energy consumption of the country.

Many devices involved in a climate system are devices that consume electrical energy and generally transform this electrical energy into heat, either by direct heating of the medium, as in the case of an electric convector, a radiant panel or a water heater, or by a heat transfer, as in the case of a heat pump or an air conditioning device.

These climatic devices, in particular electrical, are capable of storing energy by using the thermal inertia of the medium or by using internal accumulation means at the climatic apparatus, for example, by using the phase change of a substance, and said climatic devices are capable of rendering, according to some embodiments, the energy thus stored. Thus, such climatic devices are means of smoothing energy consumption particularly useful in management to regulate the production and consumption of non-storable energy, such as electrical energy, and more particularly in the framework of renewable energies such as wind power or photovoltaics.

According to a first model, mostly used to date to smooth consumption, the energy operator sets up advantageous tariff ranges and penalizing tariffs, or even load shedding, to counter consumers' natural consumption trends and to smooth their energy consumption. . Recent climatic devices, such as electric radiators, include means to optimize their operation to preserve the comfort of the user and its energy consumption, in the presence of load shedding or erasure tariffs.

At the same time, the energy operator uses different energy storage technologies, mainly by pumping water, gas compression or even storage batteries. These technologies store electrical energy in another form of potential energy, mechanical or chemical, which must be converted back into electrical energy before it can be re-injected into the grid. These modes of regulation are driven by macroscopic consumptions of energy, which are predicted from also macroscopic data, such as meteorology and the behavior of populations, and by a system of market, purchase and sale of the energy between operators interconnected by the network. This model is perfectly suited to the mass production of energy, not random, by hydraulic, thermal or nuclear power plants. However, with the proliferation of renewable energy sources, influenced by phenomena at the local scale, such as wind farms, photovoltaic units or microgeneration, whose instantaneous production potential is not determinable, this type of model is potentially at fault and leads, in some cases, to negative energy sales prices and to very large fluctuations in this selling price over periods that are not related to the responsiveness of the regulatory system.

The storage and regulation of energy consumption at the consumer terminal scale offer solutions to this problem. Thus, to shed for a few seconds or a few minutes an electric heater or an air conditioning unit has no noticeable consequence for the end user. But when this shedding is performed on a large number of devices, the drop in consumption is sufficient to contribute to the erasure of a peak consumption or to purchase energy at a reduced cost production period and resell it to a higher cost production period. Likewise, the storage of electrical energy in thermal form in a climatic device makes it possible to directly restore this thermal energy without going through the reinjection of electrical energy into the network. This mode of regulation is feasible locally, at the scale of a region, a department, a village or a neighborhood. However, consumption patterns at this much finer scale must take into account more complex influencing factors than macroscopic behavior of populations. Thus, anticipating behaviors and energy consumption requires a household approach.

The document US 2001/046792 describes a climatic system comprising one or more thermostats connected to a local network, said local network comprising a computer connected to the Internet.

The invention aims to solve this problem of the prior art and concerns for this purpose a climatic system comprising:

at. a climatic device;

b. a local network, in particular wireless, comprising a computer connected to an access means to the Internet network;

vs. the climatic apparatus comprising means, said communicating means, capable of transmitting on said local network information relating to the operation of said climatic apparatus;

d. a personal terminal;

climate system in which the communicating means of the climate apparatus are able to communicate with the personal terminal and to relay the signals of the personal terminal on the local network.

Thus, the climate system that is the subject of the invention makes it possible to collect data on the operating conditions of climatic apparatuses of a location corresponding to the extent of the local network, that is to say more commonly a home, discriminate information or behavior relating to each room in the home in which a climate device is installed, and transmit information derived from these data via the internet to a consumer control service energy or any other service. The system that is the subject of the invention does not require the climatic devices to have a static IP address and the transmission means are adaptable to an existing installation from which they benefit from the power supply. The nature of the data transmitted via the internet is determined by the computer. Thus, the climate system of the system object of the invention is able to relay the information of a personal terminal, such as a cell phone, or to issue information to this terminal to inform the owner of said terminal on the mode of operation of the system, and more generally, to interact with the owner of said terminal while the communicating means make it possible to control the system by said personal terminal. Thus, the system object of the invention takes advantage, on the one hand, of the presence in almost all parts of a dwelling of a climatic device to relay the signals of the personal terminal and dialogue with it. Since the computer of the local network is connected to the Internet, the functions of the system are shared between the climate apparatus and its own control and automation means, the local computer, a user authority connected to the computer via the internet and possibly the personal terminal. Thus, these functions are scalable and adaptable to different needs. Thus, the climatic apparatuses of the climatic system which is the subject of the invention, in addition to their primary climatic function, constitute relays between the user, provided with his personal terminal, and a much larger system, via the Internet, the functions being distributed. between these three systems.

The term computer is here used in a broad sense and it is a device comprising a processor of the input and output ports and interfaces with the local network and the access means to the Internet network, as well as than memory means.

These data are advantageously usable to refine the conditions of occupation of said premises but also for security purposes for example.

According to an advantageous embodiment, the communicating means of the system which is the subject of the invention are able to receive information from the local network.

Advantageously, the computer of the system object of the invention comprises in memory a location information of the climatic apparatus.

Thus, the system takes into account this location in the management of the different functions.

According to an advantageous embodiment of the system which is the subject of the invention, the computer is integrated in the climatic apparatus. Thus, the integration of such a climate apparatus into a room makes it possible to communicate the climate system of said local, the communication between the devices of said climate system being performed according to known means of the prior art, for example by a pilot wire or by signals carried by the power supply network.

Advantageously, the climatic system which is the subject of the invention according to this last embodiment comprises a plurality of climatic apparatuses comprising a housing for the connection of a piloting cassette, one of the plurality of apparatus comprising a suitable piloting cassette. performing the functions of the computer and other devices of the plurality comprising a cassette adapted to perform the functions of the communicating means. Thus, each of the plurality of devices is configurable to make said system communicating. This embodiment makes it possible to change the climate system that is the subject of the invention between an autonomous mode of operation and a communicating mode of operation.

The invention also relates to a method for the collection and transmission of energy data implementing a climate system according to the invention and a recipient, said user authority, which method comprises the steps of: i. obtain, via the local network, data on the operation of the climate apparatus;

ii. recording, at the computer level, said data in memory;

iv. transmit said profile on the Internet to the user authority; v. issuing from the user authority a request triggering steps iii) and iv), said request comprising information on the combination mode of the data of step iii) used to define the profile transmitted in step iv).

Thus, the process that is the subject of the invention takes advantage of the information from the system that is the subject of the invention to establish a profile of the behavior of the final consumer. This profile is advantageously used by the user authority, including, but not limited to, modeling and forecasting of energy consumption. More particularly, my behavioral profile information of the user of the climate system that is the subject of the invention is transmitted to the user authority at the moment when the latter requires it, which makes it possible to obtain a fine image of the behavior of said user.

The system object of the invention being able to dialogue, via the computer, with a user authority, said authority is able to offer services based on the information exchanged and extend the usefulness of the climate system. beyond its primary use of heating or air conditioning.

Thus, according to an example of use, a system which is the subject of the invention and whose climate apparatus includes a sensor able to evaluate a parameter relating to the quality of the air, is used for monitoring and adjusting the quality. from the air of a local.

In another example, the sensor is able to detect a presence, and the system object of the invention is used for the detection of an intrusion in a room.

The invention is explained below according to its preferred embodiments, in no way limiting, and with reference to FIGS. 1 to 4 in which:

- Figure 1 illustrates in a schematic representation an embodiment of the climate system object of the invention;

FIG. 2 is a logic diagram of an exemplary method for implementing the climate system that is the subject of the invention;

FIG. 3 is a logic diagram of another example of a method of implementing the climate system that is the subject of the invention;

and FIG. 4 illustrates an exemplary embodiment of the system that is the subject of the invention in which the computer is integrated with one of the climate devices.

Figure 1, according to an exemplary embodiment, the system object of the invention comprises a device (1 10, 140) climatic. According to this particular example, said apparatus is an electric radiator (1 10) or a water heater (140). Alternatively or from complementary way the system object of the invention comprises a climatic device such as air conditioning, reversible or not, mechanical ventilation controlled single or double flow or a fuel burning stove or a cogeneration boiler without this list is exhaustive. Generally, several types of climate apparatus are present in the system which is the subject of the invention. According to this embodiment, said electric heater comprises a temperature sensor (not shown) driving a thermostat, and an additional sensor (1 1 1), for example a presence sensor, a hygrometry sensor, a carbon dioxide sensor. carbon (C0 ₂ ), a motion detector or a smoke detector. The climatic apparatus is connected to the electrical network and comprises means (1 15) for connection to a computer (130) via a local area network, in particular wireless, of the WLAN type, or a personal network of WPAN type. According to an exemplary embodiment, this link to the network is made by a transceiver according to the WiFi® protocol, the connection means being powered by the power supply of the device. According to other embodiments, the local network is a wired network, for example using powerline on the electrical distribution network of the building or a bus ^® KNX.

In a complementary manner, the climate apparatus comprises means (not shown) for connection to a personal network, for example in the form of a transmitter according to ZigBee® KNX® or Bluetooth® standards. Thus, according to this exemplary embodiment, the climatic apparatus is capable of being connected, via this personal network, to a personal terminal (120) enabling this type of connection, for example a cellular telephone or a tablet PC. Thus, the climatic apparatus is able to relay on the local network the information exchanged with said personal terminal (120). According to another embodiment, the personal terminal is a badge comprising an electronic radio frequency tag and the climatic device (1 10) comprises means for reading said tag when it is close to said apparatus. A computer (130) is connected to the local area network and the internet, for example via a router (135). Alternatively the router (135) and the computer are the same device. The connection via the Internet is thus carried out by a wired network, by a mobile telephone network or by means of a specific cellular network for connected objects of the SIGFOX ^® type. Thus, the devices (1 10, 140) climatic system object of the invention are visible only in the local network, and only the computer has an IP address in the Internet. The entire system is installed in the same fireplace or building. Said computer (130) is able to address data and to communicate via the Internet with one or more servers (151, 152) known as "user authorities". Said user authorities (151, 152) use the formatted and calculated data transmitted to them by the computer (130). These data make it possible to establish a profile of the hearth or the building equipped with the system object of the invention, and according to the information collected, a profile of the inhabitants of the household or the users of the building.

According to one embodiment, the computer of the local network accesses information of a home automation component other than a climatic device, for example a switch, a shutter control, a smoke detector, or an anemometer, said component being directly connected to said local network, for example by means of the KNX bus, or that this home automation component is connected to said local network via a so-called personal network established with the climate apparatus.

According to a simple example of embodiment, the climatic apparatus is an electrical convector comprising an electrical resistance, a thermostat and means for controlling the supply cycles of said resistor according to the setting of the thermostat. This type of equipment is widespread in a large number of homes. The system that is the subject of the invention is adaptable to an existing installation, by equipping such a climatic device with a transmission module (115) able to broadcast on the network the instants during which the resistance of the apparatus is electrically powered and the times during which said resistor is not powered. The computer (130) easily calculates from this data and the power of the apparatus stored in its memory, the energy used for heating and the time slots during which this energy is dissipated. These data, sent to the user authority (151, 152), when associated with other data, for example the outside temperature at the location of the furnace, make it possible to determine, during a heating period, the occupation of the home and thus, for example to differentiate a secondary residence from a main residence, or to classify the home according to its actual energy performance. Most climatic devices also include sensors and advanced control means, to adapt the operating conditions of the device according to its environment or the habits of the user. Thus, most electric heaters have a temperature sensor for closed-loop control of their operation according to a target temperature. By way of example, the document FR 2 982 346 describes a climatic apparatus, adapted to adapt its operating conditions according to the actual use of the living room in which it is installed, and which comprises:

a presence, noise and vibration detector;

- environmental sensors such as hygrometry or carbon dioxide, the presence of pollutants or a light sensor;

- a window or door opening detector.

The transmission of this information to the computer and their treatment according to an appropriate model make it possible to draw a profile of the dwelling equipped with such a system and its occupants. The precision of the profile thus obtained enables the user authority (151, 152), by means of an appropriate model, to anticipate the energy consumption of the hearth, if necessary piece by piece, and to realize a diffuse storage of energy. electric in the form of heat. The climate apparatus (110) is not directly connected to said user authority, only the computer (130) is connected to the internet. Thus, the nature, frequency and quantity of information transmitted to the user authority is determined by that computer, which includes the firewall and the security necessary to protect the privacy of the users.

FIG. 2, according to an exemplary embodiment of the implementation method of the system that is the subject of the invention, during a interrogation step (210), the computer, via the local network, interrogates the apparatus (110) or climate apparatus connected to the local area network to obtain data. Upon receiving the request, according to a transmitting step (215) the climate apparatus (110) transmits information on the local area network to the computer (130). As described above, this transmitted information consists of information on the operation of the apparatus, but also information supplied by the sensors of the climate apparatus or else information resulting from a pre-treatment carried out by the means of programming and controlling said climate apparatus (110). Each The climate apparatus is identified on the local network, for example, by means of the MAC address, or physical address, of its transmitter. When the transmitter does not have a MAC address, the climate device is identified on the network by an initial dialogue protocol with the computer. Thus, the computer is able to identify the source of these data and advantageously includes in memory the characteristics of the device, as its nature: radiator, water heater, air conditioner ... its power, its position in the building and any useful parameter. According to a recording step (220), the computer sorts the data thus received, in particular according to the date and time of reception, and stores them in a memory (225). During a request step (230) the user authority (151) sends a request to the computer (130). According to an exemplary embodiment, said request comprises both a request for data transmission and a protocol for processing these data before transmission. The user authority (151) and the computer (130) are connected via the internet and the computer (130) has an IP address. Upon receipt of this request, during a processing step (240), the computer (130) retrieves the data stored in memory (225) and applies to them the processing protocol that has been transmitted to it by the authority user (151). According to a response step (250), the computer (130) transmits the result of the applied processing over the internet and the required data to the user authority (151) which retrieves them during a receive step (260).

According to an exemplary embodiment of the system which is the subject of the invention, the computer (130) is able to control the climatic apparatus (110). Either by directly addressing, via the local network, an instruction to said climatic apparatus, or by addressing an instruction to a control means able to address an order to the climatic apparatus, for example by means of a pilot wire, or by signals carried by the power supply network.

Thus, according to this embodiment of the system that is the subject of the invention, during an analysis step (270), the user authority (151) analyzes the data transmitted by the computer (130) and more generally by the climate systems connected to it and transmits, via the internet, an instruction to the computer (130). Upon receipt of this instruction, the computer (130) issues (280) an operation order to the climatic apparatus (1 10) or climatic devices constituting the climate system of which this computer is part. This mode of implementation of the method and device objects of the invention, allows the user authority to address consumption instructions more complex than a simple erasure. For example, such an instruction is to limit the heating or cooling power of the home to a defined threshold for a defined period. The management of the climatic apparatuses of the system to achieve this is carried out by the computer (130), and not by the user authority, which computer, according to the embodiment of the climate system object of the invention, performs this management by a dialogue with the means of programming and individual control of climate devices.

The exchange protocols between the user authority and the computer are here described in a simplified manner but include, in accordance with the state of the art, all the appropriate identification and authentication steps.

The exchanges between the user authority and the system that is the subject of the invention are not limited to a use aimed at smoothing energy consumption. Thus, the transmitted profiles can be used for commercial and advertising purposes by the user authority. Indeed, more particularly when the climatic apparatus of the system object of the invention are equipped with means and advanced sensors, the method of the invention makes it possible to draw a profile of users of the system outside their connection time on the internet or on social networks, and so, for example, to target promotional operations. This is all the more advantageous as the climatic apparatuses are present in almost all the rooms of the building, that it is possible to easily deploy the system object of the invention on any existing climatic installation, by the integration of modules. the system is able to transmit data on a continuous basis and that users of the system derive benefits from its installation, particularly in terms of energy saving and comfort. As such, the computer of the system object of the invention is connected via the Internet to several user authorities able to provide different services and exploiting various information. These services include the safety of goods and people, health or the optimization of comfort without this list being exhaustive.

According to another aspect of the system which is the subject of the invention, the latter is able to accept the connection of a personal terminal. According to an exemplary embodiment, the climatic apparatus comprises means of connection to the local network comprising the computer for example a transceiver according to the WiFi® protocol, or wired, in particular by carrier current using the supply power supply network of the climatic device. Said climatic apparatus also comprises means of proximity connection, for example by the Bluetooth® protocol, ZigBee®, infrared or by an antenna capable of detecting an RFID type RFID tag. Thus, when a personal terminal, such as a cell phone or a badge equipped with an electronic identification tag is close to the climatic device and the user of said terminal has authorized its connection, the climatic device is able to detect the presence of this device, to exchange information with said device and to relay this information on the local network.

FIG. 3, according to an exemplary implementation of this embodiment of the climatic system which is the subject of the invention, during a connection step (310), the personal terminal (120) being in the vicinity of the apparatus (1 10) climate connects to said device. The personal terminal (120) has an identifier which is thus communicated to the climate apparatus. Upon receipt of this connection the device (1 10) climate transmits (320) on the local network connection information and the identifier of the personal terminal to the computer (130). According to a first embodiment, the identifier of said personal terminal is stored in the computer (130) and is associated with user preferences stored in the memory of said computer. As a non-limitative example, these preferences relate to ambient temperatures according to the room occupied by the user (office, living room, bedroom) and according to the time of day. Upon receipt of the identifier of the personal terminal (120) and by the knowledge of the device (1 10) climatic near which said terminal is located, the computer (130) processes this information and addresses the device climatic an operating instruction adapted to these preferences. According to a second variant embodiment, the user possessing the personal terminal (120) subscribes, as a user, to a specific service from a user authority (152). The owner of the dwelling, for example a hotel, in which the climate system object of the invention is installed, is also subscribed to this service, as a supplier, from the said user authority (152). Thus, according to this implementation variant, during step (330) of processing of the information, the computer (130) sends to the user authority via the internet the information for detecting the presence of the personal terminal. Upon receipt of this information, the user authority communicates (340) to the computer (130) the user's preferences. On receipt of these preferences, the computer processes them (350) and translates them into instructions according to the technical specificities of the climate system before transmitting them to the climate apparatus (1 10), which adjusts (360) its operation according to of the deposit. This mode of implementation allows a user subscribed to the service proposed by the user authority to find a similar climate atmosphere in all places also subscribed to said service.

The ability to detect the proximity of the climate apparatus and a personal terminal is advantageously used in combination with other sensors of the climate apparatus, such as a presence sensor, to monitor an elderly person or to reduced capacity, in particular by taking advantage of the fact that climatic devices are distributed in all the rooms of a dwelling and that their position in these rooms generally gives them an important visibility. According to an exemplary embodiment, the person wears a badge equipped with a radio frequency tag. The information of detection of the label by the climatic apparatuses, associated with other information, such as those resulting from motion sensors, sensors of window opening, temperature or production of hot water, are addressed to the computer and combined to detect suspicious or risky behavior. For example, during hot weather, the lack of window opening, high temperature, a fixed position of the badge in the housing and the absence of motion detection in several rooms of the housing are likely to generate an alarm transmitted on internet to a user authority, which intervenes accordingly.

The proximity detection of the personal terminal, or the information delivered by the presence sensor, or a combination of these two pieces of information, is advantageously used to detect the periods of vacancy of the premises in which the climatic apparatus is installed, in particular by learning . For this purpose and by way of example, the information delivered by the presence sensor and the proximity detection sensor of the personal terminal are recorded and time stamped in the memory of the computer. Information acquired over a defined period of time are analyzed from a statistical point of view to determine the periods of occupation and vacancy of the premises. The statistical models for analyzing this data are loaded from the Internet where the data is exported to the user authority processing the data and communicates to the computer the result of this processing in the form of time slots of occupation or vacancy. Advantageously, when the climate apparatus is provided, the information from the hygrometry and CO ₂ sensors are also used for this purpose.

According to another example of implementation, the system object of the invention is able to ensure the management of the air quality of a building. For example, the control of the moisture content in the air in a dwelling or a building comprising several floors is complex and frequently results in an accumulation of moisture in the upper floors during the heating period and in the lower floors in the summer. . The combination of data from the sensors of the climatic apparatus of the system of the invention allows the computer to adapt the operation of the heating and mechanical ventilation, for example, so as to limit these phenomena. In addition, connecting the computer to a user authority can retrieve meteorological information and regulate the operation of the system accordingly.

According to another example of implementation, the system object of the invention allows its user, by subscription to a user authority, to manage his absence periods. Thus, according to an example of implementation, the water heater is gradually cut at the beginning of the period of absence and gradually put into operation before the end of the period of absence, the house is kept frost and gradually returned to temperature before the occupants return. In the case where the climate apparatus of the system equipping the housing are provided with presence or movement sensors, the system also makes it possible to detect an intrusion into the premises during the absence of users. This intrusion detection is complementary to a conventional alarm system. The presence of climate devices in many rooms and their ability to measure several parameters of the environment allows them to detect suspicious situations, in particular to detect a window or door opening by a temperature variation and to detect a presence in the room. the room. In the presence of such a suspicious situation, the climatic system computer, according to implementation examples, communicates directly, via a home automation bus, with the existing alarm system or triggers an alarm itself, for example by sending an abnormal activity detection message to the user authority.

According to a similar principle, the climate system that is the subject of the invention uses the environment sensors and, more generally, the dialogue capabilities of the system's climatic devices to detect and generate technical alerts, alone or in cooperation with other security systems. such as a fire alarm, a gas leak, a water leak or a power cut, without these examples being exhaustive.

Figure 4, according to a particular embodiment of the system object of the invention, said system comprises a plurality (410, 41 1) of climatic apparatus. Said climate apparatuses are provided with a housing adapted to receive a cassette (415, 430) called piloting cassette. According to an exemplary embodiment, said control cassette comprises electronic modules for controlling the apparatus alone and an autonomous operation thereof. According to another exemplary embodiment, the control cassette (415) comprises electronic modules for the operation of the apparatus in a network of climatic apparatuses and the exchange of information between these apparatuses. For example, said control cassette (415) comprises electronic modules, for example in the form of programmable logic circuits, for controlling the device (411) into which it is inserted, and electronic modules for transmitting and receiving data. information to and from other climate devices, over a wired network or over a wireless network. Such a climate system is able to operate in a coordinated manner between the various devices constituting it. Advantageously, one of the apparatuses (410) of said climate system comprises a control cassette (430) comprising a computer capable of connecting to the internet. Thus the insertion of this type of cassette in one of the climatic system climatic apparatus according to this embodiment makes the communicating climate system.

According to another example of implementation of the device of the invention, a location of climatic devices in the room where they are used is indicated at the computer. According to exemplary embodiments, said localization consists of in a simple information relating to the nature of the room in which the climatic apparatus is installed, for example: "room", "living room", "kitchen", "bathroom", possibly associated with the volume or the surface of said room. This information is entered into the computer's memory either by means of the personal terminal or directly into the computer, for example at the time of installation of said climate system. According to a complementary or alternative implementation mode, this information is associated with a positioning of the climate apparatus on a local plane. This positioning is performed, for example, by pointing on said plane by the user or the installer. According to yet another embodiment, alternative or complementary to the preceding, the climatic apparatus is geolocated. According to an exemplary embodiment, the geolocation is obtained via the personal terminal when the latter is provided with geolocation means such as a GPS, or via WiFi ^® neighboring terminals. Thus, in the most complete case, the computer has for each climatic device an installation, information relating to its nature and power, information with respect to the volume under its influence, information on its position relative to the floor plan, including the proximity of openings, and information on its relative position, including its distance, from other climatic devices of the facility. The location information of the climate apparatus is advantageously used in the detection functions, such as presence detection and intrusion detection, as well as in climate control functions.

According to a mode of independent or complementary implementation of the above, the system object of the invention, it comprises a step of determining the dynamic behavior of the building in which said system is installed by self-learning over a period of observation and calculation. According to an exemplary implementation adapted to convection heating or radiation, temperature rises are applied by controlling the heating power and compared to the change in temperature measured by the temperature sensor of the climatic device. This information, possibly combined and refined with the geolocation information is used to evaluate the response of the local in which the climate apparatus is placed according to the controlled climatic parameter. As a result, this information makes it possible to best manage the waking periods in which the climatic environment is maintained in so-called waiting conditions, corresponding to the control of the apparatus according to a reduced instruction, and so-called comfort periods, corresponding to conditions in which the room comprising the climatic apparatus is occupied and where the apparatus is controlled according to a comfort instruction, anticipating the transitions between these periods as a function of the time constant of the local area considered vis-à-vis the controlled climatic parameter.

Thus, according to an exemplary application, this information relating to the time constant of the local is used for the implementation of a control method comprising the steps of:

- determine the dynamic behavior of the building;

- deduce according to the characteristics of the climatic apparatus, its environment and climatic conditions a time of rise in temperature;

- Acquire from the memory means of the computer the vacancy areas of the premises;

- program the reduced set periods as a function of the unoccupied ranges, the rise time and the operating periods imposed at reduced temperature.

- calculate the value of the reduced setpoint according to the conditions and predictive information obtained via the Internet;

- detect a vacancy in the room above a certain threshold and reduce the reduced setpoint so as to limit energy consumption in the event of prolonged vacancy.

The predictive information is, according to an exemplary embodiment, derived from data and algorithms collected and implemented by the user authority. Thus, the information making it possible to predict the periods of occupation or vacancy includes, for example, meteorology or even information relating to road traffic. To this end, in order to define a probability of occupation of the building and according to an exemplary embodiment, an application is installed on the mobile phone of the user of the home, which application exchanges with the user authority, the position of said mobile phone . The distance between the user and his dwelling is addressed by the user authority to the computer of the climate system, or, more advantageously, a probability of arrival of the user in his dwelling at defined times, for example:

- probability of arrival in at most 15 minutes: 0.2;

- probability of arrival in at most 30 minutes: 0.5;

- probability of arrival in no more than 60 minutes: 0.95.

The temperature setpoint is adjusted according to this probability and the time constant of the building, possibly differentially between each room of the housing according to the time.

By combining the operating principle presented above with the location information of the climate apparatus, the system that is the subject of the invention is used to implement a load shedding profile, said to be intelligent, making it possible to maintain the power at all times. consumed below a defined threshold while ensuring optimal comfort for the user. Thus, the power consumed is known at any time by a measurement made on the meter according to methods known from the prior art. Via the local network, the computer receives at any time information relating to the operating behavior of the climatic apparatuses of the installation as well as information on their environment, in particular on the occupation or the presence in the rooms in which said climatic apparatuses are installed.

As a non-limitative example, if the maximum consumption target is exceeded, the choice of the devices to be shed is done by the computer in the order of priority and the following rules:

- The temperature sensor of the climate apparatus measures an ambient temperature above a threshold value, for example 21 ° C, said threshold value can be differentiated according to the room of the housing considered;

- The room is unoccupied and the climate system is in economic mode that is to say with a reduced setpoint;

- the room is unoccupied and the climate system is in comfort mode;

- the room is occupied and the climate system is in eco mode;

- the room is occupied, and the climate system is in comfort mode;

- the climate system is in frost protection mode;

- when two climatic appliances have the same priority level, the appliance whose deviation between its set temperature and the ambient temperature of the room is the weakest is selected in priority;

- if the unloaded climate system is in a room where there are several appliances whose power demand is equal to or greater than that of the shed device, the computer controls a rotation of the load shedding order between the different appliances responding to the criterion in the room.

The above description and the exemplary embodiments show that the invention achieves the desired objectives, in particular it makes it possible to open complex, interactive and evolutive operations to a climatic system, including in the case of an existing installation and to optimize the operation of this system in order to save energy and to reduce energy consumption. The climate system and the method of the invention make it possible to analyze the behavior of the users and to anticipate consumption conditions at a local scale, while at the same time retaining the autonomous operating capacity of the climate system.
