Abstract
Method of thermal management of a building, on the basis of a thermal system equipped with a low-power generator, characterized in that it comprises a step (E 3 ) of turning on the generator ahead of time in the absence of any occupant in the building so as to comply with a future comfort setpoint at a future instant (H), by taking account of the energy available (E generator — H ) at the generator up until this future instant (H) and of the energy necessary (E heating — H ) to reach the future comfort setpoint within the building at this future instant (H).
Claims
exact text as granted — not AI-modified1 . Method of thermal management of a building, on the basis of a thermal system equipped with a low-power generator, wherein it comprises a step (E 3 ) of turning on the generator ahead of time in the absence of any occupant in the building so as to comply with a future comfort setpoint at a future instant (H), by taking account of the energy available (E generator — H ) at the generator up until this future instant (H) and of the energy necessary (E heating — H ) to reach the future comfort setpoint within the building at this future instant (H).
2 . Method of thermal management of a building according to claim 1 , wherein the future comfort setpoint is a temperature setpoint and in that it comprises the following steps:
(E 1 )—Calculation of the energy available (E generator — H ) at the generator up until the future instant (H); (E 2 )—Calculation of the energy necessary (E heating — H ) to reach the setpoint temperature within the building at this instant (H); (E 3 ′)—Comparison of the above two values and turning on of the generator if E generator — H <E heating — H .
3 . Method of thermal management of a building according to claim 1 , wherein the future comfort setpoint is a maximum duration (tmax) permitted so as to reach a comfort temperature in case of necessity at the future instant (H).
4 . Method of thermal management of a building according to claim 3 , wherein it comprises the following steps:
(E 1 )—Calculation of the energy available (E generator — H ) at the generator up until the future instant (H); (E 2 )—Calculation of the energy necessary (E heating — H ) to reach the setpoint temperature within the building at this instant (H); (E 3 ″)—Comparison of the above two values and turning on of the generator if H>tmax.
5 . Method of thermal management of a building according to claim 4 , wherein it comprises a step of calculating a low setpoint temperature to regulate the operation of the generator in the absence of any occupant in the building, this low setpoint being variable over time.
6 . Method of thermal management of a building according to claim 1 , wherein it comprises a step of inputting at least one of the following data:
Inputting of at least one temperature setpoint in the case of occupancy of the building and/or in the case of non-occupancy; and/or Inputting of the periods of occupancy and/or of non-occupancy of the building; and/or Inputting of a permitted maximum duration (tmax) of operation of the generator so as to reach a certain comfort temperature in the building.
7 . Method of thermal management of a building according to claim 1 , wherein it comprises a step of evaluating the future exterior temperature over several instants (H) of a future period (P).
8 . Method of thermal management of a building according to claim 1 , wherein it comprises a step of auto-learning of the thermal characteristics of the building.
9 . Method of thermal management of a building according to claim 1 , wherein it comprises the calculation of the energy available (E generator — H ) at the generator up until the future instant (H) through the following equation:
