Abstract

The invention relates to a method for estimating the fuel supply of a boiler, for a building (2) having a boiler (4) and energy accumulation means (4′), in order to ensure a desired indoor temperature during an autonomy period P, this method including the following steps:

a) making an estimation of the average outdoor temperature during the autonomy period P,

b) determining the consumption of the building (2) in order to ensure said desired indoor temperature, depending on the previous estimation of the average outdoor temperature,

c) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required for providing this energy.

Claims

1. A method for estimating the fuel supply of a boiler, for a building having a boiler and energy accumulation means, in order to ensure a desired indoor temperature during an autonomy period P, this method including the following steps:

a) making an estimation of the average outdoor temperature during the autonomy period P,

b) determining the consumption of the building in order to ensure said desired indoor temperature depending on the previous estimation of the average outdoor temperature,

c) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required for the boiler for providing this energy.

2. The method according to claim 1, wherein step a) applies a measurement of an outdoor temperature, either instantaneous and/or conducted during a period prior to the autonomy period P.

3. The method according to claim 1, wherein step b) applies a determination of a characteristic of the building, a so-called energy signature, which represents the consumption of the building depending on the difference between an indoor temperature T_inL and an outdoor temperature T_ouL.

4. The method according to claim 3, wherein the estimated heating needs and the actual heating needs are compared for a period prior to the period P, and the energy signature is corrected depending on the result of this comparison.

5. The method according to claim 1, wherein, step c) at least takes into account:

the heating autonomy at the beginning of the period P,

the maximum amount of energy which may be stored in the accumulation means,

the minimum amount of energy which may be loaded into the boiler,

and the maximum amount of energy which may be loaded into the boiler.

6. The method according to claim 5, wherein the amount of energy to be loaded is equal to the smallest of the following two amounts:

the difference between the maximum energy which may be stored in the accumulation means and the available energy in the accumulation means;

the maximum energy which may be loaded into the boiler,

and this while being larger than the minimum energy which may be loaded into the boiler.

7. The method according to claim 1, wherein an estimation of at least one instantaneous outdoor temperature is further made during the autonomy period P, and an hourly distribution of the heating needs is estimated during this period P.

8. A device for estimating the fuel supply of a boiler having accumulation means, for a building, including a computer programmed for:

a) determining the consumption of the building in order to ensure a desired indoor temperature for an autonomy period P, from an estimation of an average outdoor temperature during the autonomy period P,

b) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required by the boiler to provide this energy.

9. A heating system for a building, including:

a boiler for carrying out combustion of a fuel, and means for accumulating energy,

a device, according to the preceding claim, for estimating the fuel supply of the boiler.

10. The heating system according to the preceding claim, further including at least one sensor measuring at least one temperature outside the building and at least one indoor temperature.

11. The system according to claim 9, further including sensors measuring the amount of energy available in the accumulation means.

12. A building having a heating system according to claim 10, and heating means.

13. A heating system for a building, including:

a boiler for carrying out combustion of a fuel, and means for accumulating energy,

a device for estimating the fuel supply of the boiler, said device including a computer programmed for;

a) determining the consumption of the building in order to ensure a desired indoor temperature for an autonomy period P, from an estimation of an average outdoor temperature during the autonomy period P,

b) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required by the boiler to provide this energy.

14. A building having a heating system, including:

a boiler for carrying out combustion of a fuel, and means for accumulating energy,

heating means,

at least one sensor measuring at least one temperature outside the building and at least one indoor temperature,

a device for estimating the fuel supply of the boiler, said device including a computer programmed for;

a) determining the consumption of the building in order to ensure a desired indoor temperature for an autonomy period P, from an estimation of an average outdoor temperature during the autonomy period P,

b) determining the amount of energy to be provided depending on the previous consumption, and the amount of fuel required by the boiler to provide this energy.
