Definitions
- the present invention relates to a method of controlling an electric heater. More specifically, the present invention relates to the management of rapid drops in temperature, for example when opening a door or window.
- Document EP0175125 describes a method of heating regulation which, in the case of a rapid decrease of ambient temperature, triggers a limitation phase during which the heat emission is limited to a value present before said rapid decrease. This value is then gradually increased until the set temperature is reached or until an increase in the ambient temperature, which triggers the stopping of the limiting phase.
- a disadvantage of this method is that it does not allow to anticipate the rapid drop in temperature, since the limiting phase is not triggered before a rapid decrease in said temperature.
- the invention aims to solve this problem. More specifically, the invention relates to a method of controlling an electric heater, said apparatus comprising a probe adapted to measure an ambient temperature of a room receiving the apparatus, said method comprising the following steps: the temperature ambient is measured at three successive times; then the temperature change rates are compared over a first and a second consecutive time interval; then, if the ambient temperature decreases on both intervals and if the rate of decrease is higher on the second interval, then a heat emission by the apparatus is limited to a value present before the first time.
- the heat emission is limited as soon as the acceleration of the temperature drop is observed, ie from the beginning of this decrease if an opening on the outside air has been put in place in the room.
- the method then comprises the following steps: the ambient temperature is measured at a fourth time; then the temperature change rates are compared on the second time interval and a third interval between the third and fourth time; then, if the ambient temperature decreases on both intervals and if the rate of decrease is higher on the third interval, then the heat emission is still limited to a minimum value lower than the value present before the first time. Said minimum value may be zero, i.e. the heating is off.
- the ambient temperature does not increase on the third interval and if the rate of decrease on the third interval is not greater than the rate of decrease on the second interval, it is possible, according to an embodiment of the invention. invention, to maintain the heat emission at the present value before the first time. The heat emission can then be limited to the minimum value after a further measurement of the ambient temperature, if the latter continues to fall.
- the ambient temperature can only go up if the opening period has been short and if the walls of the room have accumulated enough of heat to warm the air.
- a preferred form of the invention provides that if the minimum value of heat emission is zero, and if the ambient temperature does not increase over a first duration greater than an interval between the first and fourth times, the heat emission value is increased.
- Said first duration is preferably chosen much higher than the intervals between the first and fourth times.
- the invention further relates to an electric heating apparatus, comprising a probe adapted to measure an ambient temperature of a room receiving the apparatus, said apparatus being provided with means for implementing a method as described herein. -above.
- the single figure shows a schematic view of an electric heater according to one embodiment of the invention.
- the apparatus 10 comprises a means 1 1 for heating, comprising for example a heating electric resistance.
- the apparatus 10 further comprises a regulating device 12, to which is connected a probe 13 which measures the ambient temperature Ta of a room 18 in which the apparatus 10 is located.
- the device 12 comprises in particular a microprocessor 14, a program memory 15, a memory 16 of data, these elements being connected by at least one bus 17.
- the probe 13 measures the ambient temperature Ta of the local 18, at regular intervals, for example of a duration of the order of half a minute or minute.
- the heating means 11 1 delivers a certain amount C of heat, which varies over time according to the heating requirements of the room.
- This operating mode corresponds to a default programming of the device 10.
- the program memory 15 also contains a program 19 which makes it possible to regulate the operation of the apparatus 10 in the event of communication of the interior of the room 18 with the outside air, for example when opening a room. window 20.
- the probe 13 measures the ambient temperature T a o at a first time to, corresponding to the moment of the opening of the window 20.
- the probe again measures the ambient temperature (Tai, Ta2) at a second time ti and a third time .2 successive.
- the decrease in the ambient temperature generally triggers an increase in the amount of heat emitted by the heating means, in order to raise the temperature towards the set point.
- the detection of the contact with the outside air triggers a limitation of the quantity C of heat emitted by the apparatus 1 1 to a value Co, corresponding to the amount of heat emitted before the first time to.
- the program 19 prevents the opening of a window 20 from triggering an increase in the energy consumption of the apparatus 10.
- the limitation intervening at the detection of an acceleration of the temperature drop, said limitation takes place very quickly after opening the window.
- the value Co corresponds to a significant amount of heat, resulting in a significant waste of energy if this Co value is maintained throughout the opening time of the window 20.
- the program 19 provides that the probe 13 measures the ambient temperature Ta3 at a fourth time .3, after the time .2.
- the heat emission is still limited to a minimum value Cmin, stored in the data memory.
- Cmin is less than the value Co.
- Cmin may be zero or correspond to an "out-free" mode of the apparatus 10.
- the program 19 can then provide to move to the Cmin value after a further measurement of the ambient temperature, if the latter continues to fall. More precisely, the ambient temperature Ta4 is measured at a fifth time t 4 . If Ta4 is less than Ta3 then the heat emission is limited to the Cmin value.
- the window 20 is closed again.
- the heat emission of the apparatus 10 is limited to the value Cmin. If the probe 13 detects a rise in the ambient temperature of the room 18, the device 12 considers that the window 20 is closed and then returns to its default program, which aims to maintain the set temperature Te in the room. The heating means 1 1 then increases its heat emission.
- the temperature of the room 18 can increase only if the walls 21 of said room are able to release accumulated heat, so as to heat the indoor air of said room.
- the window 20 has been open for a long time, the walls 21 have cooled down and the ambient temperature of the room 18 will not rise after closing the window. This closure will not be detected and heat remission of the device 10 will not be restarted.
- the program 19 preferably provides for a rise phase of the heat emission, after a time ⁇ much greater than the time intervals between two measurements of the ambient temperature.
- the value C of heat emission is then increased. It is for example reduced to the value Co present before the drop in ambient temperature.
- the emission of heat at the value Co is maintained over a duration ⁇ 2, recorded in the data memory and in particular calculated according to the parameters of the local 18 and the apparatus 10.
- This duration ⁇ 2 must allow the ambient temperature to rise if the window 20 has actually been closed.
- the probe 13 measures the ambient temperature at the end of ⁇ .2. If the ambient temperature has increased, the default program is reactivated, so as to bring T a to the set temperature T c .
- the device 12 If the ambient temperature has not increased after ⁇ 2, the device 12 considers that the interior of the room 18 is still in contact with the outside air.
- the heat emission value C is again limited to the value Cmin.
- the temperature rise phase can be periodically reactivated, for example at regular ⁇ intervals, as long as the ambient temperature does not increase.
- a second form of the invention aims to minimize the energy waste associated with the temperature rise phase.
- the device 12 measures the duration ⁇ between the passage of the value C to the value Co and the detection of a possible rise in temperature by the probe 13. In fact, if the room 18 is always in contact with the outside air, the duration ⁇ will be greater than if the window 20 is closed.
- the device 12 considers that the window 20 is still open.
- the heat emission value C is again limited to the value Cmin.
- the duration ⁇ .2 may be chosen shorter than in the first form.
- the temperature rise phase can be periodically reactivated, for example at regular ⁇ intervals, as long as the ambient temperature does not increase.
