Definitions

  • the invention relates to an apparatus as defined in the introductory portions of claims 1 and 9 and to a method as stated in the introductory portions of claims 6, 7 and 8.
  • a heating regulation principle is known in heating systems in which a room sensor and a floor sensor measure room temperatures which are subse- quently used as a basis for a regulation of the room temperature.
  • the desired room temperature can be set by a user, following which the system ensures that both floor temperature and room temperature are above or equal to the values set by the user.
  • the determination of the con- trol parameters for the floor sensors is a fixed constant relationship which is statically associated with the room temperature set by the user.
  • a drawback of the system of the above-mentioned type is that it does not allow for the circumstance that the com- fort criteria of persons in the room concerned do not depend uniquely on the threshold values . This leads to several drawbacks, one being that the system frequently "overregulates “ in several situations so that the consumption of energy is increased inexpediently. Alterna- tively, depending on calibration and control strategy, the system will perform a control which results in "overregulation” in some situations and “underregulation” in other cases, thereby reducing the comfort as the temperature is felt to be too low.
  • the object of the invention is to provide a space heating system which provides a pleasant and comfortable room temperature, it being another object of the invention to achieve an energy-saving heating strategy.
  • the invention relates to a heat regulation device for the regulation of the temperature in a room by heating means in response to at least one room temperature representing signal and at least one predetermined or user-settable reference temperature, said heat regulation device being adapted to control heating means, said heat regulation device being adapted to adjust or weight the reference temperature or the room temperature representing signal directly or indirectly in response to one or more addi- tional temperature representing signals fed to the device.
  • a very advantageous regulation of space heating is obtained according to the invention.
  • a very important ad- vantage of the invention is that the heat regulation makes it possible to provide a comfort temperature which is pleasant for the persons who might be present in the heated room.
  • the invention instead of weighting entered or predefined "compulsory criteria", the invention rather provides an advantageous heat regulation which takes it into account that the mean temperature of the room "goes" vertically up and down in the room, depending on the current need for energy supply to the room, so that the comfort for the persons present in the room is not only determined on the basis of a fixed temperature, but can be weighted relatively to a temperature measured in the vicinity of the floor of the room, the current energy need and the room temperature .
  • a further and very important advantage of the invention is that the improved comfort is achieved with a strongly reduced energy consumption.
  • the saving should be seen in the light of the fact that, to a great extent, the human body does not perceive lower temperatures in the higher strata of air as being unpleasant if reasonably high temperatures occur in the vicinity of the floor. According to the invention, this fact makes it possible to down- weight the room temperatures desired by the user and to save energy thereby without this being at the expense of the heating comfort .
  • a further aspect of the invention is that the regulation strategy may be implemented by means of two sensors placed in the room, i.e. a room temperature sensor and a floor temperature sensor, in contrast to other systems which require the use of an outdoor sensor.
  • a regulation system according to the invention is simple and inexpensive to manufacture, just as the mounting and putting-into-service costs are limited because of the limited physical extent of the system.
  • An important advantage according to the invention is thus that, in dependence on the surrounding environment, i.e. e.g. type of insulation, degree of ventilation, etc., the properties of the room in terms of temperature can be derived from the algorithm without using more than two out- door sensors in the optimum embodiment.
  • the room temperature representing signal is typically measured by one or more sensors which are placed 5-10 cm down in the floor. Other positions, however, are also possible .
  • the heating means are floor heating means
  • a special advantage is achieved according to the invention, since the heating strategy gives by far the best result with low-positioned heating means which radiate uniformly in the room.
  • vector heating a quite special synergy must be achieved when the invention is used for the control of floor heating.
  • sensors e.g. one onboard sensor for meas- uring room temperature and one external sensor for measuring floor temperature or a temperature near the floor.
  • a really good comfort is achieved, since the temperature distribution can be controlled uniformly over the entire floor face of the room.
  • Heating means broadly mean heating means such as electrical heating wires , heating pipes , etc .
  • fig. 1 shows a room with a heating system according to the invention
  • figs. 2A-2C show how the temperature is regulated in accordance with an example according to the invention.
  • Example Fig. 1 shows a room 1 with a floor 2.
  • Heating means 3 in the form of electrical heating wires are embedded in the floor. It will be appreciated that other heating means may be used in a corresponding manner .
  • the heating means 3 are controlled by a heat regulator 4 having an onboard temperature sensor (not shown) which currently measures the room temperature .
  • An advantageous mounting height may e.g. be about 1 m, typically determined by the height at which the user wants to use the regulator.
  • the regula- tor 4 is additionally connected with a temperature sensor 6 which measures the temperature in the vicinity of the floor 2. This sensor may advantageously be placed 5-10 cm down in the floor. Positions on or just above the floor are also possible.
  • the position of the floor temperature sensor according to the invention is very important since the basis for the regulation is precisely this sensor, while the room temperature sensor may be considered as being secondary.
  • the temperature sensor 6 is connected to the heat regulator 4 wirelessly or via fixed cabling (not shown) .
  • the heat regulator 4 is provided with a button 7 for setting a user-defined room temperature or more par- ticularly comfort temperature.
  • a heat regulator according to the invention will be described more fully below.
  • Figs. 2A-2C show an example of how a heat regulator ac- cording to the invention is arranged.
  • the regulator 4 is arranged in accordance with a very simple embodiment, the floor temperature measured by the sensor 6 and the room temperature measured by the onboard sensor being incorporated as simple on/off values. That is the heating means 3 are activated if both of the two determined threshold values have been reached. According to the invention, however, an additional internal weighting of the desired room temperature programmed by the user is carried out in response to the measured floor temperature. This weighting will be illustrated below with reference to figs. 2A-2C.
  • the floor temperature has been measured to be +20 °C by the sensor 6.
  • the room temperature has likewise been measured to be +20 °C by the onboard sensor (not shown) in the regulator 4.
  • An outdoor state that might e.g. provide the shown situa- tion may e.g. be +10 °C .
  • the algorithm according to the invention performs no correction of the threshold values, but activates the heating means 3 in a simple manner if both threshold values have not been exceeded.
  • the floor temperature has been measured to be +22 °C by the sensor 6, and the room temperature threshold value has therefore been weighted internally in the regulator 4 by -0.2 °C for each 1 °C the floor temperature exceeds +20 °C .
  • the automatically adjusted value of the value of +20 °C set by the user has thereby been reduced to +19.6 °C .
  • the algorithm according to the invention thus performs a correction of the room temperature threshold value and activates the heating means 3 in a simple manner if both threshold values have not been exceeded, i.e. +19.6 °C and 22 °C .
  • An outdoor state that might e.g. provide the shown situation may e.g. be 0 °C .
  • the floor temperature has been measured to be +24 °C by the sensor 6, and the room temperature threshold value has therefore been weighted internally in the regulator 4 by -0.2 °C for each 1 °C the floor temperature exceeds +20 C.
  • the algorithm according to the invention thus performs a correction of the room temperature threshold value and activates the heating means 3 in a simple manner if both threshold values have not been exceeded, i.e. +19.2 °C and 24 °C .
  • An outdoor state that might e.g. provide the shown situa- tion may e.g. be -10 °C .
