Definitions
- the present invention relates to the field of thermal regulation of a room.
- thermal performance of buildings is at the heart of the issues and depends on the quality of the insulation, the quality of the internal heating but also the external conditions in order to offer good thermal comfort.
- An external condition to take into account is the thermal contribution of solar radiation, impacting the comfort in a building.
- the solar flux is first absorbed by the materials. Then, with accumulation, the absorptive capacity of the materials decreases. At the beginning, the heat transmitted to the building/room is lower than the instantaneous contributions by sunshine. The heat then increases gradually to become maximum after a certain time. When the sunshine has ceased, all the heat stored by the walls is gradually released.
- the greater the thermal inertia of the building, i.e. a heavy structure the lower the maximum real contributions due to the sun will be, and the more it will be delayed in relation to the instantaneous flux passing through the glazing. This is different in the case of a 100% glass structure of the veranda type.
- Veranda-type buildings and structures with low thermal inertia, light type will therefore be much more sensitive to overheating in the event of significant and/or direct sunlight. There is therefore a risk that the solar flux is added to the interior heating of the building and causes a feeling of thermal discomfort.
- the present invention therefore proposes to solve these drawbacks by providing a system and its method making it possible to obtain better thermal management of a room.
- the invention relates to a system for regulating the temperature of a room integrated into a building, such as a veranda, equipped with one or more external glazing, functional, activatable by electric current, distributed by group(s) comprising:
- At least one sensor configured to measure at least one quantity representative of the external solar radiation at the level of each group of glazing
- At least one sensor configured to measure the outside temperature and at least one sensor configured to measure the inside temperature
- At least one power supply box connected to each sensor and configured to power each glazing unit individually according to a current and/or a voltage that can be varied
- control box connected to each power supply box, so that the control box receives the signals corresponding to the measurements made by the sensor(s) connected to each power supply box, and that it emits electrical control signals to each electrical supply unit according to the quantities measured by the sensor(s) of the corresponding glazing.
- the system comprises two sensors configured to measure the interior temperature making it possible to limit at least two distinct zones for which the electrical control signals differ.
- the sensor configured to measure at least one quantity representative of the external solar radiation measures the illumination.
- the sensor configured to measure at least one quantity representative of the external solar radiation measures the quantity of energy of the solar radiation.
- the system further comprises an infrared sensor 18 allowing the measurement of the different infrared radiation emitted by the bodies of the people in the room, said control box using this measurement of the different infrared radiation emitted by the bodies of the people in the room. to generate the electrical drive signals to each power supply box
- the invention further relates to a method for controlling a system according to one of the preceding claims, the room being equipped with at least heated exterior glazing, the method comprising the steps consisting in: a) defining a setpoint temperature and a comfort temperature, lower than the set temperature; b) defining an outside temperature threshold value and a threshold value of a quantity representative of the outside solar radiation; c) measuring at least one temperature inside the room and comparing it to the setpoint temperature; d) if the temperature inside the room is lower than the set temperature, determine the electrical power to be applied to the heated glazing and apply it, e) measure the outside temperature and the quantity representative of the outside solar radiation and compare them with the threshold values; g) adapt the power level if the temperature inside the room is higher than the comfort temperature, if the outside air temperature is above the threshold value of the outside temperature and if the quantity representative of the outside solar radiation is greater than the threshold value the quantity representative of the external solar radiation.
- the system comprises two sensors configured to measure the interior temperature making it possible to limit at least two distinct zones and to provide two measurements of the ambient temperature, the power level of each group of glazings of each zone being adapted if the temperature ambient air temperature of the zone is greater than the comfort temperature, if the outdoor air temperature is greater than the outdoor temperature threshold value and if the quantity representative of the exterior solar radiation is greater than the threshold value the representative quantity external solar radiation.
- the power level of each zone is adapted if the ambient air temperature of the zone is higher than the comfort temperature, if the outside air temperature is higher than the threshold value of the outside temperature and if the magnitude representative of the exterior solar radiation is greater than the threshold value the magnitude representative of the exterior solar radiation.
- the power level is adapted if the ambient air temperature of the zone is higher than the comfort temperature, if the outside air temperature is higher than the value threshold of the outside temperature and if the magnitude representative of the exterior solar radiation is greater than the threshold value the magnitude representative of the exterior solar radiation.
- the sensor configured to measure at least one quantity representative of the external solar radiation measures the illumination.
- the sensor configured to measure at least one quantity representative of the external solar radiation measures the quantity of energy of the solar radiation
- the threshold value of the quantity representative of the external solar radiation is at least 80000 Lux, preferably at least 90000 Lux.

- the measurement of the illumination is associated with a measurement of the duration of illumination, the threshold value of the duration of the illumination being between 5 and 15 minutes, preferably equal to 10 min.

- FIG. 1 -figures 1 to 4 are schematic representations of a room provided with electrically controllable glazing according to the invention and variants.
- FIGS. 5 and 6 are illustrations of the first variant of the invention.
- FIG. 7 is an illustration of the second variant of the invention.
- FIGs 1 and 2 is shown a room 1 using the system according to the invention.
- This room can be of the veranda type.
- the veranda 1 comprises a plurality of panes 3 which can be activated by electric current.
- Each glazing 3 is then provided with a functional layer which, when energized, allows a function to be performed.
- the function operated is a heating function.
- the functional layer is a metal layer deposited by known deposition methods such as PVD or CVD.
- Each pane 3 is electrically powered individually by a power supply box 5, as shown in Figure 2. Thus, depending on the level of current sent to the pane, the latter provides a certain amount of heat.
- each power supply box 5 electrically supplies at least two panes 3 via a separate electrical connection for each pane 3.
- a single power supply unit 5 could also supply a single pane 3, or even three panes or more.
- the glazings 3 can be powered alone or in groups of at least two.
- the regulation system comprises for each glazing 3, an electrical connection assembly.
- Each electrical connection assembly is configured to electrically connect a glazing 3 to the power supply unit 5 which supplies it, when the sash carrying the glazing 3 is in the closed position.
- the connection assembly is configured to electrically disconnect the glazing from its power supply box 5. This advantageously makes it possible to cut off the power supply to a glazing, in particular to a heated glazing, when an opening of the sash is made.
- the system is equipped with one or more indoor temperature sensors 15 to improve the management of the thermal comfort of the room.
- the system regulation comprises at least two interior temperature sensors 15, for example located at two opposite ends of the room as visible in FIG. 4. This makes it possible to measure a possible temperature gradient of the air inside the room and, at using this information, to optimize the heating of the room.
- the system can also include an outside temperature sensor 16 making it possible to know the outside temperature and used to improve the management of the heating of the room.
- the temperature sensors 15, 16 are connected to a control box 7 as shown in Figure 3.
- the connection between the sensors 15, 16, the power supply box 5 and the control box 7 is of the wireless type.
- the transmission of data between the power supply boxes 5, the sensors 15, 16 and the control box 7 then advantageously does not require any physical installation. In addition to simplifying the installation of the control system, this also makes it possible to modify the location of the control box 7 in the veranda without significant constraint.
- the control unit 7 thus comprises the control algorithm for the glazings 3 in order to regulate the temperature of the room.
- the control unit 7 comprises a memory space in which a setpoint value Te for the interior temperature of the room.
- This set value Te allows the control box 7 to control said glazing 3 that can be activated by electric current.
- the control unit 7 is able to send one or more commands to the windows 3 in order to supply them with electric current in order to activate the functions of these windows, here a heating function.
- each pane 3 or group of panes is associated with a measurement module 9.
- This measurement module 9 is configured to include at least one sensor 90 able to measure a quantity representative of the external solar radiation.
- Each measurement module 9 is connected to the power supply unit 5 via an electrical connection assembly, in order to transmit the measurements to the control unit 7.
- the control box 7 is thus able to use at least this quantity information representative of the external luminous flux to refine the control of the glazings. More precisely, the control unit 7 and the regulation are such that this quantity information representative of the external luminous flux makes it possible to adapt the level of current sent to the glazings 3 and therefore the heat emitted.
- the memory space of the control box 7 includes a threshold value VL of the quantity representative of the external solar radiation. This threshold value VL is chosen as a function of the geographical location of the room.
- the quantity representative of the external solar radiation is the illumination, expressed in lux.
- the horizontal illumination can exceed 100,000 lux, while in the spring it will be around 80,000 lux.
- a value of 90000 lux for the threshold value VL of the quantity representative of the external luminous flux can be chosen.
- this single quantity information representative of the external solar radiation is insufficient to allow effective control.
- this unique quantity information representative of the external luminous flux it is understood that if the measured value is greater than or less than the threshold value then the level of current sent to the glazing is adapted: it is lowered or increased.
- the disadvantage is that this information alone can lead to a drop in the heating power of the glazing even when the temperature inside the room is too low.
- the memory space of the control unit 7 also includes a threshold value Ti representative of a comfort temperature and a threshold value Te representative of the outside temperature.
- the comfort temperature Ti is the temperature at which a person feels good.
- the threshold value representative of a comfort temperature Ti is chosen to be lower than the setpoint temperature value Te.
- the comfort temperature Ti is chosen to be at least 1°C lower than the setpoint temperature.
- the threshold value representing a comfort temperature Ti is set at at least 19°C.
- the comfort temperature is set at 20°C.
- the outside temperature is used because, as mentioned before, a room of the veranda type is a room with low thermal inertia. If this means that the external heat is quickly transmitted to the interior of the room, this also means that the cold is also quickly transmitted to the room. It is therefore necessary that the adaptation of the level of current sent to the glazings 3 does not take place to the detriment of the heating of the room.
- the threshold value representative of an outside temperature is set at at least 16°C, preferably set at 18°C. This temperature is similar to the average temperature in Paris during the summer.
- control unit 7 is arranged to perform a measurement of the outside temperature via the outside temperature sensor 16, a measurement of the inside temperature via the inside temperature sensor 15 and a measurement of a quantity representative of solar radiation. outside.
- the control unit 7 can thus compare the measured value of the exterior temperature with the corresponding threshold value, the measured value of the interior temperature with the corresponding threshold value and the measured value of a quantity representative of the exterior luminous flux with the corresponding value and generate a control signal to be sent to the power unit 5 of the glazings.
- VL i.e. 90000 Lux
- control unit 7 deduces from this that the external temperature and lighting conditions and the internal temperature conditions are such that there is a risk of overheating. Indeed, if the interior temperature is equal to or higher than the comfort temperature and if the exterior temperature reaches or exceeds the value of 18°C and if the level of illumination is at a high level with at least 90000 lux then the conditions of the room are such that the contribution of heat due to the illumination of the sun can be added to the heat in the room and cause overheating knowing that the heated windows 3 are active.
- the control box 7 thus generates a control signal to adapt the current level in the glazings 3.
- This control signal is thus sent to the power supply boxes of the glazings so that they adapt the current level to reduce it or even set it to zero.
- This decrease in the level of current in the glazing causes a drop in thermal energy and therefore in the heat released by the these glazings 3. Consequently, the heat given off by the glazings does not overlap less or no longer overlaps with that generated by the external luminous flux so that the thermal comfort in the room is better.
- Measurements of the outdoor temperature of the indoor temperature via the indoor temperature sensor 15 of the illuminance are carried out at regular intervals. Thus, when the temperature, interior temperature and lighting conditions are no longer met, then the control unit 7 generates and sends a control signal to increase the level of current in the glazing.
- the criterion on the level of illumination is coupled with a time criterion.
- the lighting is subject to the vagaries of the weather and in particular to the clouds which could move and position themselves opposite the sun, lowering the level of lighting. In doing so, the condition of the illumination value could no longer be fulfilled causing the generation of a new control signal from the control box 7.
- a time condition can be associated with this illumination condition. This association makes it possible to prevent a temporary drop in lighting from modifying the control of the glazing.
- This time condition is therefore a time delay lasting between 5 and 15 minutes, preferably 10 min. consequently, if the duration of illumination, the value of which is greater than the threshold value, is greater than a threshold value previously defined at 10min and the other conditions are met, then the adaptation of the power level is carried out.
- a second embodiment is such that the magnitude sensor representative of the exterior solar radiation 90 is a solar radiation sensor.
- These solar radiation sensors are able to measure the quantity of energy of the direct and diffuse solar thermal flow (W/m2).
- W/m2 the quantity of energy of the direct and diffuse solar thermal flow
- This second execution advantageously makes it possible to overcome a possible cloud passage since these sensors make it possible to measure the power of the flux different from the notion of illumination.
- the amount of solar thermal flux energy (W/m2) depends on various criteria such as geographical position, exposure / orientation of the collector.
- a threshold value of the amount of usable solar thermal flux energy (W/m2) is at least 300W/m2. This value is an estimated value for temperate zones. Of course, it is conceivable that this threshold value may vary according to the geographical area and the configuration of the veranda-type room.
- the control box is arranged to operate a finer control as a function of the quantity representative of the external solar radiation.
- the control box 7 is able to send a control signal to adapt the current level of a glazing 3 or group of glazings according to its measurement of the quantity representative of the external solar radiation.
- each measurement module 9 sends data, to the control box 7, concerning a measurement of the quantity representative of the external solar radiation.
- this measurement may vary from one glazing 3 or group of glazings to another depending on the orientation of these glazings or groups of glazings 3.
- a glazing 3 oriented East does not receive the same solar radiation as a glazing 3 facing West.
- the consequences are different for south-facing glazing and for north-facing glazing.
- control unit 7 is capable, for each pane 3 or groups of panes, of using the measurement of the quantity representative of the solar radiation in order to carry out the test using the quantity representative of the luminous flux, the interior temperature and the temperature exterior.
- the control box 7 is thus capable of sending, for each glazing or group of glazings, a control signal making it possible to adapt the level of current. In doing so, the heat given off by a glazing exposed strongly to the external luminous flux is reduced while the other glazings which are less exposed to external solar radiation will not see their control modified, or it will be modified differently.
- FIG. 5 and 6 an example is illustrated showing a part provided with four panes A, B, C and D.
- the panes A and B are exposed to the sun so that the housing pilot 7 generates a control signal for these glazings A and B in order to adapt their heating power.
- the glazings C and D are exposed to the sun so that the control unit 7 generates a control signal for these glazings C and D in order to adapt their heating power.
- the room L is divided into several zones Z, each zone Z being provided with a temperature sensor interior.
- the division of the room L can be done with respect to an axis X as shown in FIG. 7.
- the room can have dimensions or a configuration where internal temperature differences are possible. As a result, the risks of feeling overheated are not identical throughout the volume of the room.
- each glazing 3 or group of glazing is associated with an interior temperature sensor so that the test using the quantity representative of solar radiation, the interior temperature and the exterior temperature uses the interior temperature of the sensor associated with the glazing or group of glazing.
- the glazings A', B' and F' are located in a first zone while the glazings C′, D′ and E′ are located in a second zone.
- a setpoint temperature and a comfort temperature can be defined for each zone.
- the measurement module 9 further comprises a sensor able to measure a specific characteristic of the glazing.
- This specific characteristic may be the surface temperature of the glazing, an electrical resistance of the glazing or a light intensity, or a combination of these.
- This specific characteristic is used by the control box to refine the control of the current level. For example, depending on the electrical resistance of the glazing, sending a defined level of current causes a certain amount of thermal energy, this being due to the Joule effect principle (R x
- the room further comprises a sensor of the infrared sensor/camera type 18.
- This sensor of the infrared sensor/camera type 18 is oriented in the living room of the veranda-type room.
- This infrared camera 18 records the various infrared radiations (heat waves) emitted by the bodies and which vary according to their temperature to assess the temperature of the people inside the room.
- This sensor 18 is used in parallel with the sensor 90.
- This variant assumes that even if the solar radiation does not exceed the threshold triggering a modification of the heating power of the glazing, a people in the room may feel overheated. Indeed, the presence of many people in the room can cause an increase in the temperature in the room but also an increase in the temperature felt by these people.
- the sensor of the infrared sensor/camera type 18 is arranged to be pointed at the area where the people are or to be mobile and scanned the room in order to measure the various infrared radiation (heat waves) emitted by the people located there. in the premises.
- This measurement makes it possible to measure an increase in the body temperature of the people present and makes it possible to anticipate a feeling of discomfort.
- the power adaptation is done if the temperature rise is at least 2°C.
- the sensor 18 is connected to the control unit 7 so that the data from this infrared camera sensor 18 is used for controlling the heated glazing.
- the indoor temperature is higher than the comfort temperature, i.e. 19°C.
- the measured radiation value exceeds the defined threshold value or if the sensor 18 measures an increase in the body temperature of the people present in said room, preferably by at least 2°C.
- control unit may further comprise a database comprising temperature values and the quantity representative of the solar radiation for different places or climates.
