Definitions

  • the invention relates to a hot water heating system with a heat meter according to the preamble of claim 1.
  • a heat meter is known, which is its output signal proportional to the instantaneously supplied amount of heat by measuring the heat transfer flow and the heat transfer temperature in the flow and return to the heat exchangers and determining the difference between these two temperatures.
  • the amount of heat supplied per unit time i.e. H. the heat output over a specified period of time
  • the total heat consumption is determined and displayed. This value is then used to determine or distribute heating costs.
  • a control device for the gas-fired boiler of a hot water heating system is known from EP-A1 62856, in which on the one hand the gas quantity corresponding to the measured heat requirement is supplied to the burner via a gas control valve and on the other hand the combustion air quantity supplied to the boiler is constantly adapted to the gas quantity supplied.
  • a heat demand characterizing measured variable for the regulating device is in eizwasservorlauf H and disposed in the heating water depending on a temperature sensor and both temperature sensors are connected to the input of a Master controller connected. If the temperature difference deviates from a specified setpoint, the heating gas supply is increased or reduced accordingly using a servo pressure regulator.
  • the object of the invention is to improve the temperature control in a hot water heating system of the type mentioned, in particular to avoid strong temperature fluctuations, and to make the best possible use of the fuel supplied, or in a hot water heating system of the latter type to generate a respective heat requirement to simplify characteristic signal.
  • This object is achieved by the invention characterized in claim 1. It essentially consists in simultaneously using the heat consumption meter or heat meter for heat consumption measurement to control the respective heat output, i. H. to utilize the burner capacity in such a way that the burner or another heat source is only operated with the power that is currently sufficient to cover the currently required heat. This leads to an optimal functioning of the burner and utilization of the fuel.
  • the radiators 1a, 1b, 1c are connected via a flow line 2 as well as a circulation pump 3 and a return line 4 to the heat exchanger 5 of a boiler 6, which is heated by a burner 7. Between the heat exchanger 5 and the flow and return lines 2 and 4 the heat consumption meter 8 is switched on, which constantly measures the total amount of heat supplied to the radiators 1 and provides an output signal corresponding to this heat output on its output lines 9.
  • the gas supply to the burner 7 is controlled by a gas control device 11, in which a safety valve 14 and a main gas valve 15 are connected in series between inlet 12 and outlet 13.
  • the safety valve 14 works together with a switch-on pushbutton 16 and a restart lock 17 of known construction.
  • the closing body 15 of the main gas valve is biased in the closing direction by a closing spring 18 and can be lifted off the valve seat 21 by means of a membrane 19 by the servo control pressure in the chamber 20 against the force of the closing spring 18.
  • the control pressure for the chamber 20 is supplied via the channel 22 by a servo pressure regulator 23, the setpoint of which can be adjusted by means of an electromagnetic drive 24.
  • a room thermostat 25 In a room to be heated by the hot water heating system there is a room thermostat 25, the contact of which closes as soon as the room temperature measured by its temperature sensor falls below the setpoint set on the room thermostat. A switching signal thus arrives at the electrical controller 26, which on the one hand switches on the gas control device 11 and on the other hand controls the amount of gas supplied to the burner 7 via its electromagnetic drive 24.
  • the structure and mode of operation of the gas control device 11 are known from EP-62 856 and are therefore not explained in detail.
  • a control pressure proportional to the heat requirement builds up, which lifts the closing body 15 from the seat 21.
  • gas flows via line 52 to injector nozzle 53, which faces gas inlet 54 of burner 7.
  • the gas flow sucks at the same time Primary air and also leads it to the burner 7.
  • the pilot burner 28 is connected to the gas control valve via an ignition line 27. Its flame heats the thermocouple 29, which keeps the safety valve 14 open via the magnet insert 30.
  • a second injector nozzle 55 is provided, which faces a secondary air inlet 31 of the boiler 6.
  • the second injector nozzle 55 is connected via a line 32 to the outlet 33 of an air control valve 34, to which compressed air is supplied by a blower 35.
  • the closing body 36 of the air control valve is biased in the closing direction by a spring 37 and can be lifted by a control pressure in the chamber 38 via the membrane 39 from the valve seat 40 as soon as the pressure in the drive chamber 38 is that of the closing spring 37 and the pressure in the outlet 33 exerted forces on the membrane 39 exceeds.
  • the structure and mode of operation of this air control valve 34 are also known from FIG.
  • the amount of air supplied to the second injector nozzle 55 is controlled with the aid of the electromagnetic drive 41 acting on a servo pressure regulator.
  • an oxygen or carbon dioxide sensor 43 is provided in the flue gas outlet 42, the output signal of which is fed to a second electrical controller 44. If the excess of oxygen (excess air) in the flue gas discharge 42 falls below a predetermined setpoint value, the controller 44 supplies an output signal to the magnetic drive 41 of the servo pressure regulator 45 placed on the air control valve 34, whereby the setpoint value of this pressure regulator is increased and at the same time the air control valve 36, 40 is opened further .
  • the room thermostat 25 is usually arranged in the most important of the rooms to be heated, for example in the living room.
  • radiator thermostats 47a and 47c known per se, can be assigned to the radiators 1a and 1c there in other rooms in order to maintain a desired temperature in these rooms.
  • the room thermostat can also be equipped with a timer and devices for lowering the temperature during the night. Room thermostats of this type, so-called clock thermostats, are also known.
  • the room thermostat usually provides a simple switching signal, which indicates that the supply of heat to the room in question is required. This signal can be triggered not only by a room thermostat, but also by any other sensor. However, it does not indicate how large the heat requirement of the room or even the entire heating system is.
  • the heat output required by the burner depends on this particular heat requirement. If only a little heat is required, a full load operation of the burner would lead to an overheating of the heat transfer medium and thus to an undesired excess temperature in the space mentioned and to a waste of fuel. On the other hand If the burner is operated with too little power, it will take a disproportionate time before the desired room temperature is reached. It is therefore important both for reasons of comfort and for economic reasons, in particular for reasons of energy saving, to adapt the performance of the burner to the respective heat requirement.
  • the output signal of the heat meter 8 is used, which, for example in the form known from EP-B1 24 778, generates a signal proportional to the amount of heat currently supplied to the heating system.
  • This signal is usually integrated over time and is therefore a measure of the heat consumption or energy consumption of the heating system.
  • this signal is simultaneously used to constantly adapt the heat output of the burner to the particular heat requirement of the heating system.
  • said output signal is fed to an integrator 48 equipped with a timer, which measures the amount of heat consumed during a predetermined period of time and stores a signal corresponding to this amount of heat.
  • a comparator 49 is connected to the integrator 48, which compares the amount of heat measured during the aforementioned time period with the amount of heat measured during a previous time period of the same duration, and from this generates a signal controlling the heat output and outputs it to the controller 26 via the line 50.
  • the output signal on line 50 of comparator 49 influences the control signal of controller 26 transmitted via line 51 to electromagnetic drive 24 of gas control valve 11 for the amount of gas to be supplied to the burner.
  • the amount of air required for complete and thus optimal combustion is automatically established by, as mentioned above, measuring the excess air by means of the sensor 43 and using the controller 44 and the electromagnet 41 to control the secondary air supply to the second injector nozzle 55.
  • a major advantage of adapting the burner output to the respective heat requirement and determining this heat requirement on the basis of the quantity of heat supplied to the heating system is that all external influencing variables which change the heat requirement are automatically recorded. You do not need a separate outside temperature sensor, nor further sensors for wind speed, humidity, sunshine or the like.
  • the burner output is set in such a way that the required amount of heat is made available within a predetermined time in order to avoid undesirable temperature fluctuations. Only as much heat is generated as is actually required. This means at the same time that the burner with lower power is in operation for longer periods, which reduces the exhaust gas temperature and thus the heat loss through the chimney. The burner always works with the best possible efficiency.
  • the integrator 48 and the comparator 49 can be formed by a microprocessor, which can also be part of the electrical controllers 44 and 26. The two controllers 44 and 26 together with the integrator 48 and the comparator 49 are advantageously combined to form a common electronic control device with a common power supply.
