    METHOD AND DEVICE FOR HEATING A BUILDING AND CONTROL UNIT FOR ROOM HEATING
    In recent decades, the efficiency of space heating installation has increased. In the 1980s, high-efficiency boilers (HR) were introduced on a large scale in the Netherlands. If the return water from a high-efficiency boiler reaches a temperature of approximately 53 ° C, the high efficiency is reduced and unnecessary heating energy is lost via the flue gas channel.
    It is also known to heat buildings on the basis of so-called weather-dependent control, possibly with room temperature sensing (RTC), whereby the temperature of the central heating water is determined depending on the outside temperature. When a heating curve is used, use can also be made of so-called radiator thermostats or group controls, whereby the temperature of each room is set.
    According to the present patent application, a method is provided for heating a building comprising a number of spaces, comprising the following steps: predetermining the desired amount of heated fluid for each space based on the temperature desired in that space as well as by calculations or measurements to certain properties of that space or zone, supplying fluid heated thereby from a heat source; measuring the outside temperature and / or wind force and / or wind direction, the temperature of the fluid also being adjustable on the basis thereof; measuring the temperature in each of the spaces or zones to the control unit connected by the heat appliance is delivered; and controllably supplying the amount of fluid with the desired temperature to the heating elements in each of the spaces.
    It will be clear that the measurement of the outside temperature, wind force and wind direction can also be done by a weather service, and is available for example via the internet.
    According to preferred embodiments of this method, calculations are made in advance of the relevant space to be brought to a specific temperature. This concerns fixed values, for example (not limited to) the content of the room or zone, the capacity of the one or more heat emitters such as radiators, etc. placed therein, the insulation value of the walls, roof, floors and windows as well as the all then there is no presence of a ventilation system, a type thereof, the humidity and air quality, etc. For a certain room, the setting can even be changed, until a sensor determines that a sensor window has been opened, etc. etc.
    Preferably, an optimum CH water temperature is determined within one or more rooms in a given room on the basis of the calculations made beforehand, the outside temperature and the desired temperature. The capacity of the CV can be adjusted with this. By calculating the spaces in advance together with the desired temperature, it is possible to calculate how much heat a particular space requires. This allows losses to be limited.
    The outside temperature and / or the wind direction and wind speed are preferably measured by sensors arranged on the outside of the building. In this context, it is noted that the north side of a building generally requires more heat than the south side. Naturally, the wind direction and wind speed can significantly influence the heat demand.
    Preferably in each of the zones or the radiators (or other heat emitters) are provided with controllable valves, whereby zones or spaces where there is no significant heat requirement these valves can completely close the radiators.
    Preferably, use is also made of a variable flow rate, wherein by controlling the controllable valves per space the predetermined amount of fluid can be supplied in a controllable manner.
    An advantage of using a variable flow rate is that the return water water temperature of the water flowing out of the radiators can be lowered, which can increase the efficiency. When using a variable flow rate with controllable valves per space, a further advantage is that mixing valves become superfluous. This also makes it possible to control the supply of the predetermined amount of fluid with greater precision.
    The radiators are preferably supplied with fluid of relatively low temperature at an early stage, so that losses are limited and the efficiency is further increased.
    In further preferred embodiments of systems according to the present invention, depending on the existing situation, considerable savings can be realized starting from approximately 30% less consumption to approximately 70%.
    Further advantages, features and details of the present invention will be elucidated with reference to the following description of a drawing of a preferred embodiment thereof, in which:
    FIG. 1 is a schematic view of a building in which the embodiment of the method and system according to the present patent application is arranged;
    FIG. 2 is a schematic view of the control system according to the present invention;
    FIG. 3 is a block diagram of the control system according to a preferred embodiment of the present patent application; and
    FIG. 4 is a flow chart of a portion of control from FIG. 3.
    For example, in a building 10 (Fig. 1) consisting of two floors with an attic, which can be an office, business premises, a residential home, a basement or attic, radiators 30, 31 ... are provided in most rooms. A temperature sensor 40.41 ... is also arranged in more than one room. The supply of the heat fluid to the radiators is controllable with the aid of a remote, wired or wireless control valve, which can also be arranged for a specific zone that comprises two or more spaces, such as a storey, attic, basement and the like.
    In the present example there are, for example, six rooms on the ground floor, for example two offices on the north side 11,12 a toilet group 13, a general room 14, a reception room 15 and a reception 16 on the south side and an office enclosed between the reception and an office on the north side.
    When adjusting the system according to the present patent application, the capacity of the on-site heating, e.g. 4.5 kW, 6 kW, 12 kW and 5 kW, as well as the degree of insulation and content of the room so that it is possible to set what is most efficient for the radiator in a certain room. For example, it may be desirable for the water temperature on the north side to be (considerably) higher than on the south side, e.g. 72 ° C vs. 60 ° C, while it is also important that a central heating boiler 28 remains in condensing operation, that is to say that the return temperature is preferably below 50-55 ° C as much as possible, or - often - below 53 ° C.
    In an even more preferred embodiment, when only one heating device is used, the temperature of the heating water and the power are connected by a control unit at any desired time.
    Furthermore, the building according to the present patent application is provided with a temperature sensor 21 on the outside and an anemometer 22. On the basis of the outside sensor, existing temperature installations often determine the temperature of the water that comes out of the heating installation, whereby either on the north side it is too cold, but no doubt energy is wasted on the south side of the room.
    In the present exemplary embodiment, the building is provided with three central heating boilers 28, 28 ", 28", for example with a capacity of 20 kW each (kilowatts). The measured or calculated data of the room and the radiators are entered in a control unit; With the help of a (wireless) connection, for example via WiFi, with a tablet computer or a PC, the desired temperature in the room can be obtained at any desired time.
    For this purpose a voltage to resistance value converter is placed between the control unit and each of the central heating boilers which is connected to the outside sensor input of the central heating boiler, in the present preferred embodiment comprising a pulsating, light-emitting diode (LED) light source 26 (Fig. 2) as well as a light-sensitive resistor (LDR) 27 which is connected to the input of the central heating boiler where normally the signal from the outside sensor, i.e. the NTC resistor, is connected.
    It will be clear to a person skilled in the art that the connection is also very possible with the aid of other (digital) techniques, such as a processor in cooperation with bus technology etc. etc.
    For example, the present example uses water temperature of 72 ° C on the north side and water temperature of 60 ° C on the south side, water temperature of approximately 35 ° C in the reception (underfloor heating), a water temperature of 55 ° C in the clamped office on the east side and a water temperature of approximately 45 ° C in the toilet group on the south side. A water temperature of 65 ° C is used in the general area as calculations have shown that, given the degree of insulation, this gives the best heating of the rooms. If certain areas are hardly occupied, or hardly at all, during a certain time, the temperature can of course be reduced, which can result in considerable savings, especially in offices and schools.
    Because one or more central heating boiler (s) are included in the system, they can each be operated with a different water temperature; of course it is a mixer that is controlled from the electronics to place in different zones (one or more spaces) and to adjust and control the temperature via the control unit 20. The output of the control unit determines the power of a boiler to be delivered which will be determined to a considerable extent by the outside temperature and information of the desired temperature increase, while the temperature of the water can be adjusted via the voltage to resistance value converter whereby certain zones and the like can be reduced with CV water of reduced temperature heated.
    The capacity of the three boilers is calculated at an outside temperature of -10 ° C at 15 m / s wind speed. If boilers have a modulation rate of 25%, the minimum power to be supplied is 5 kW. If it is determined in the morning that the outside temperature is -10 ° C, and the inside temperature is 10 °, a signal of 6 V can be output from the control unit on a scale of 0-10 V, the first boiler then burns at 60%.
    With the aforementioned example of a light-sensitive resistor and an LED, a certain resistance value is offered from the control unit, as a result of which the boiler thinks that the outside temperature CH requires water of 65 ° C. The photosensitive resistance is influenced by causing the LED to flash with a pulse width modulated signal and the resistance value will then be varied as desired depending on the pulse width.
    For example, if more office space needs to be heated, the first boiler starts running at full capacity (10V = 100%) and the delivery temperature remains at 75 ° C. In a particular preferred embodiment, an electronic mixing valve may be included in the circuit for admixing colder water in order to prevent supply water that is too hot.
    If more heat is required, calculations will be made in the control units or, for example, two boilers will run at 50%, which may be advantageous in terms of efficiency.
    Furthermore, pump speeds can of course be set and a central heating boiler can be set to intermittent if the degree of modulation has become too low.
    Further improvements in efficiency and comfort can be achieved by applying a variable flow rate within the heating system. As a result, within a heating installation it can be controlled dynamically by the control unit that the desired amount of heated fluid is available at the desired location. The controllable valves per zone / space are herein preferably chosen such that the positions of the controllable valves substantially determine the flow per space / zone. In the case of a variable flow rate, a controllable or demand-driven pump is preferably used, e.g. a pressure-controlled pump. In addition, in the case of a variable flow rate, depending on the heat demand and calculated properties of the zones / rooms, the central control unit can control the central heating water temperature so that as little energy as possible is used.
    Expectedly and depending on the starting position, an energy saving can be obtained with a method and device according to the present patent application of at least 30% and it cannot be excluded that this can be twice as much in certain buildings (30-70%).
    If the control unit, which generally comprises at least one processor and a memory, reaches a request for heat demand in space 1,2,3, etc., schematically indicated by 40, 41 and 40, respectively. 42, calculations are made based on the fixed values for the heat capacity of the respective spaces as stored at 51 while, for example, calculations are also made with the aid of the variable values that appear from the measured temperature and wind speed and direction.
    After the calculation, the control unit controls the CV devices 28, 28 ', 28 ”as indicated in Figure 2, that is to say with a first signal for indicating the power demand on a scale of 0-10 V and with the other signal via a voltage-to-resistance converter so that the water temperature can be controlled. In addition, on the basis of the calculations 40-42 for the rooms, mixing valves for mixing the heated radiator water with return water are controlled as schematically indicated with 63, 64 and 65 respectively, and shut-off valves arranged at each radiator are also opened, respectively. closely controlled depending on the heat demand. At 61 it is indicated that underfloor heating can also be controlled without a mixing valve, since underfloor heating is provided with its own pump.
    After calculating the fixed and variable value as indicated in figure 4 (70), a signal of 0-10 V as well as a pulse width modulated (PWM) signal is sent to the LED in order to control CV device 28 (28 ') (71 ).
    The position of the mixing valve is adjusted at 72. At 73 it is determined whether a certain set value has been reached after, for example, 15 minutes. At 74 it is checked whether the temperature is too high, at 75 whether the temperature is too low for the loop to be repeated through 72. At 76 the desired end temperature of the room has been reached.
    Such a flow chart can also be set up with a floor heating system, although a mixing valve does not have to be controlled, since a floor heating system has its own pump and control valve.
    It is clear from the above that the newly proposed system is both cost-effective and comfort-enhancing. In the described preferred embodiment, a central heating device is used, but it will be clear that other heat sources are conceivable, such as district heating or other systems.
    If there are two heating sources in a room, for example underfloor heating and air heating and a ventilation system without heat recovery, the system will be set up in such a way that floor heating is not used, which is generally more efficient: the system knows there that the ventilation system prior to the heat demand the room will ventilate for example for half an hour.
    Preferably the desired supply temperature of the fluid is obtained by a mixing valve which continuously adjusts the degree of mixing of the return water and the central heating water of higher temperature.
    Because the system makes it possible to accurately control which temperature must be supplied with which capacity, it is also possible to optimally control at night, during the weekend or during the week, for example in ecclesiastical spaces, so that much energy can be saved.
    The present invention is not limited to the above described preferred embodiments thereof; the rights sought are defined by the following claims within the scope of which many modifications are conceivable.
