Definitions
- the present invention relates to a method of self-balancing a heating device.
- a heating device can be used both for heating air in premises and for heating sanitary water. It will be developed the case of a device for heating the air of a room, the method according to the invention can easily be adapted by those skilled in the art to other known heating devices.
- a heating device comprises at least one heat emitter, for example an electric radiator.
- the heater includes a probe and a thermostat to maintain a substantially stable ambient temperature.
- the purpose of the sensor is to inform the heating device of the ambient temperature.
- Said probe may be an outdoor sensor, an indoor sensor, or any other type of probe for giving the heating device a reference temperature.
- the function of the thermostat is to determine a temporal charge rate of the heat emitter. This charge rate must be such that it makes it possible to maintain the ambient temperature substantially equal to a temperature desired by the user. Said temperature desired by the user is called the set temperature or setpoint.
- the temporal charge rate of the heat emitter represents the operating ratio of the heat emitter, ie for example that a load ratio of 30% represents a heat emission of the heat emitter during 30% of its running time.
- the thermostat allows a user of the heater to adjust the set temperature.
- the thermostat comprises a control box, typically a mechanical or electronic device.
- a mechanical control box it may be a graduated dial.
- an electronic control unit it may be a control box comprising a display device as well as adjustment buttons such as a "plus” button and a "minus” button. Such buttons allow to increase or decrease the set temperature. The set temperature is then displayed via the display device.
- the heater may include one or more heat emitters.
- the thermostat can be a single general thermostat for controlling one or more heat emitters or an individual thermostat incorporated in each heat emitter, or a combination of these devices.
- a single probe can provide information on the ambient temperature one or more thermostats.
- the room sensor raises the ambient temperature.
- the data recorded by the probe are sent to the thermostat.
- the thermostat compares the temperature read by the sensor to the set temperature defined by the user using the thermostat.
- the thermostat regulates the room temperature by setting the time charge rate of the heat emitter. Said regulation is performed according to regulation parameters well known to those skilled in the art. The temperature difference between the setpoint temperature and the ambient temperature is one of these control parameters.
- the regulation can, for example, be a "all or nothing" type regulation, a proportional type of regulation, a proportional integral type regulation or other. The case of a proportional type regulation will be studied later, the method according to the invention being easily adaptable by those skilled in the art to other types of regulation.
- Proportional type control has the advantage of providing a stable control of the ambient temperature by changing the time charge ratio of the heat emitter as a function of the temperature difference between the set temperature and the ambient temperature. Such regulation is carried out within a temperature range. This temperature range is called the proportional band.
- the proportional band defines a standard deviation between the setpoint temperature and the ambient temperature for which the thermostat control type is applied.
- the thermostat sets a nominal load rate of 100% or 0%, depending on whether the ambient temperature is above or below the temperatures in the proportional band. This nominal load rate at 100% or at 0% returns as quickly as possible to the ambient temperature in values belonging to the proportional band.
- the thermostats according to the state of the art whatever the type of regulation applied, increase or decrease the charge rate of the heat transmitter to the maximum; that is to say that said thermostats according to the state of the art define and apply a nominal load rate of 100% or 0%.
- stationary charge rate is meant the charge rate in regulation at a constant setpoint temperature preceding the setpoint temperature change.
- a high stationary charge rate is for example of the order of 75%.
- Transition charge rate means the charge rate defined by the thermostat during an increase in the set temperature such that the ambient temperature is outside the proportional band.
- the heat emission of the heating device during the transition period is only slightly greater than the heat emission of the stationary period heating device.
- the transitional period is the period during which the thermostats according to the state of the art define and apply the nominal charge rate to reach the new setpoint temperature. This small difference between the charging rates therefore causes a small rise in the ambient temperature.
- the difference between the stationary charge rate and the transient charge rate is important.
- the transient heat emission is then much more important than the stationary heat emission.
- Such a difference in heat emission causes a significant rise in temperature and abrupt.
- the heat emitter still provides additional heat for a short period of time. During this time, the ambient temperature exceeds the set temperature, it is an overheating. The lower the charge rate of the old set temperature, the greater the overheating.
- One possible solution to solve this problem may be to keep in a memory changes in the rate of charge for all possible changes of instructions.
- the memory would have for each setpoint change, between the old setpoint temperature and the new setpoint temperature, a variation of the charge rate to prevent overheating or overcooling.
- the invention provides a method for regulation during a rapid setpoint change and avoiding overheating or over-cooling in the room.
- the method according to the invention does not require a large storage of data allowing such a regulation.
- the method according to the invention adapts to all kinds of setpoint changes, and this, regardless of the room in which is installed the heater.
- the method according to the invention provides for breaking down the heating time of the heating element in cycles. These cycles are intended to observe the behavior of the heater over a short period of time.
- the charge rate of the heat emitter is calculated at each new cycle.
- the method according to the invention defines a transient temporal charge rate which is not necessarily 100%, or 0%. More particularly, the method according to the invention calculates a temporal charge rate by means of the regulation system and modulates this temporal charge rate. Typically, the control parameters are changed during the transition period. These modified parameters are applied throughout the transition period.
- the charge rate calculated by the thermostat control system is calculated with modified control parameters to prevent overheating.
- the calculated charge rate is modulated by taking into account the charge rate of the heat emitter before the change in the set temperature. Such a modulated charge rate is then applied to the heat emitter.
- the subject of the invention is therefore a method of heating using a heating device comprising a thermostat, a probe and a heat emitter, the method comprising:
- a step during which the energy supply of the heat emitter is regulated by means of the heating command said heating command comprising a temporal charge rate defined as a function of regulation parameters, said parameters being stored in a data memory, a difference between the ambient temperature and a set temperature being one of these parameters, - a step during which the set temperature is modified, characterized in that:
- the operating time of the heating device is decomposed into heating cycles, the temporal charge rate being calculated for each cycle by a control program, the said charge rate being equal to a proportion of the cycle during which the heat is emitted
- a step is performed during which the control program is modulated to calculate a transient load rate different from a nominal load rate as a function of a stationary load ratio, said stationary load ratio corresponding to the charging rate the heater before changing the set temperature,
- the transient charge rate is applied to the heat emitter.
- modulation of the control program takes place only during cycles during which the ambient temperature is outside a proportional band, said proportional band defining a standard deviation between the ambient temperature. and the setpoint temperature, for which the regulation is carried out without modulation.
- a preferred embodiment of the invention provides that the The modulation for each cycle is based on the change in temperature difference between the room temperature and the set temperature.

- the radiator 3 comprises a resistor 6 emitting heat. This resistor 6 heats the ambient air as a function of heating commands transmitted by the thermostat 5 to the radiator 3. Typically, the thermostat 5 defines a temporal charge rate to be applied by the radiator 3.
- the purpose of the probe 4 is to record a reference temperature, for example an ambient temperature. This temperature reading is carried out regularly during a step of the method according to the invention.

- the button 24 for changing the operating mode can allow to influence the operating program selected in the program memory 12 which is used by the microprocessor 10. It is known, for example, thermostats with operating programs for an economic mode, a comfort mode or a mode frost free. These operating programs are defined in the program memory 12 of the thermostat 5.
- the data processing by the microprocessor 10 is performed by different operating programs according to the selected operating mode.

Once the data on the charge rate 16 to be applied defined by the microprocessor 10, these data are sent via the bus 9 to the 8 output interface. The heating commands are then sent to the radiator 3. A control box 25 of the radiator 3 receives the heating commands. This control unit 25 can also be used to receive the power supply 2 necessary for the proper functioning of the heat emitter. The heating commands are analyzed by the control box 25 which causes said commands to be executed on the radiator 3.
