Definitions

  • the present invention relates to a process and a device for regulating central heating for an individual or collective residential building.
  • the object of the present invention is to implement a method which makes it possible to avoid the above drawbacks.
  • the subject of the invention is a method of regulating a central heating of a building in which at least once a day the temperature setpoint changes to a reduced value, method according to which a temperature of the heat-transfer fluid is continuously measured, and the heating control is slaved to a value of the interior temperature estimated by successive approximations from the temperature of the heat transfer fluid and the thermal properties of the heating network, characterized in that, to estimate the interior temperature, we set uses a combination of two models, a particularly precise "network” model during periods of shutdown or reduction in heating, and a particularly precise "building” model when the temperature of the fluid is high.
  • the various parameters of said models have plausible initial values that are not optimal at the time of commissioning, and they are optimized by self-learning in a few days.
  • the present invention also relates to a device allowing the implementation of the above method.
  • It includes a regulator, possibly integrated in the central heating boiler, the input of which is connected to a single device for measuring the temperature of the fluid and the output of which is connected to the control of the burner of the boiler or to a control of three- or four-way valve.
  • ⁇ 1 should not be treated as an instantaneous value, but as an average value over a sufficient time interval, or better as an average value weighted by the inertial response factors of the network, ie for example : ⁇ ' i (t) being a family of exponential memories of the instantaneous charge rate ⁇ (t), based on different characteristic times ⁇ ti: from, approached by:
  • This model involves two parameters p 1 and p 2 . These can also be established by self-learning, taking advantage of the hourly programming, as will be explained below.
  • the regulator can interrupt the heating - generally for several hours - when the setpoint changes from the normal value at reduced value; ⁇ 1 tends to zero, so that ⁇ i becomes well known, because it is close to ⁇ f.
  • the value obtained constitutes a precise reference, which can be injected into the "building" model (see below), in order to estimate with good precision what was the value of ⁇ i during the change of setpoint, and of deduce a condition from p 1 and p 2 .
  • the law f ( ⁇ i 1 , ⁇ f, ⁇ 1 ) 0 can be disturbed by local actions, such as for example the limiting actions of thermostatic valves.
  • the temperature of the fluid ⁇ f is higher at a given charge rate.
  • the application of the law f leads to an overestimation of ⁇ i , and therefore to a reduction in heating. This reduction is useful because the action of thermostatic valves means that the demand for heating is lower than the supply.
  • the regulator mainly regulates the average interior temperature of the building, with however a partial adaptation to the demand expressed by the local adjustment actions.
  • g (t) intervenes in a corrective term whose amplitude is of the order of 1 to 2 ° C. It reflects the fact that the outside temperature, the solar gain, the internal gain, are statistically higher during the day than at night. Being a corrective term, we admit on g (t) a certain degree of approximation, allowing the use of a preprogrammed function.
  • the sensitivity parameter p3 by self-learning; indeed, the indoor temperature is well known thanks to the "network” model some time (about two hours) after the heating stops due to each drop in setpoint. It then suffices to compare this temperature with the value given by the "building” model, and to correct p 3 accordingly.
  • the "building" model remains precise when the temperature of the fluid is high, provided that the reference ⁇ i 1 (to) is sufficiently recent. We can then limit the role of the "network” model to the detection of indoor temperature excursions linked to unpredictable changes in climatic conditions and occupancy.
  • the "building" model also makes it possible to implement a heating anticipation function, when the setpoint is reduced, in anticipation of the future transition to a normal setpoint: the temperature evolution should be estimated on the assumption of 'operation at full load, and to trigger said operation when the temperature estimated for the time of transition coincides with the normal setpoint.
  • the regulator continues to regularly use the self-learning functions, in order to adapt to any changes in the definition of the context.
  • the parameter P4 can undergo significant seasonal variations (higher values in mid-season than in winter), and the provisional condemnation of certain convectors can modify the parameters ⁇ p (i) ⁇ , p 1 , p 2 of the "network" model.
  • FIG. 2 represents a test result of a regulator according to the invention, applied to the heating of an inhabited dwelling, immediately after commissioning.
  • the interior temperature setpoint (curve T), the interior temperature estimated by the regulator (curve ⁇ i 3 ), the temperature of the fluid (curve ⁇ f ) has been shown;
  • the effective interior temperature ⁇ i and the sunshine (W / m 2 - curve S) are also given, which are not measured by the regulator.
  • the set temperature T is 20 ° C except between 11 p.m. and 6 a.m., where it is 17 ° C.
  • the "building" model provides a maximum correction g (t) around 3 p.m., hence the minimum temperature of the fluid, in accordance with the reduction in requirements, linked in particular to solar gains (curve S).
  • the regulator orders the heating to stop.
