Definitions

  • the invention relates to gas boilers of the sealed type with forced draft and relates more precisely to a new mode of regulation by microprocessor.
  • a regulation system must also ensure a safety function both at the time of ignition but also during operation by monitoring the temperature in various places of the appliance to correct excess or insufficient temperature or secure the device if necessary. To this end, the regulation must collect and analyze at each instant as a function of the determined setpoint values, characteristic signals of deviations from these values, supplied by sensors.
  • the invention provides a microprocessor-based control system which avoids these drawbacks and provides all of the control functions. lation and safety, while allowing 1a verification at all times of the device regulation card by simulating commands.
  • this microprocessor-based regulation allows systems to be adapted by a simple change of memory without touching the components, it also provides a much finer proportional and integral proportional action regulation and also has advantages over dimensional plan.
  • the device shown is made up of a sealed enclosure 1, the bottom of which isolates the sealed part from the mechanisms and members of this regulation arranged at the bottom, the assembly being mounted on the same frame, not shown.
  • an L-shaped exhaust gas exhaust hood 2 caps a fin block 3 which constitutes the heating body of the appliance, the skirt 4 of which channels the gases coming from the burners 5.
  • an exhaust fan 6 On the vertical part of the chimney hood is fitted with an exhaust fan 6, the drive motor 7 of which occupies the space provided between the hood and the upper part of the enclosure.
  • the fan 6 extracts the combustion gases via an exhaust pipe 8 coaxial with the air intake pipe 9.
  • the latter opens into an air distributor housing 10 placed at the upper part of the sealed enclosure, itself in communication through an orifice 11 with the interior chamber.
  • the solenoid valve 12 for admitting gas to the burner supplied by a gas inlet pipe 13, by means of a circuit breaker housing 14 which ensures also the electric powering of the boiler.
  • the reversing valve 15 the closing member of which is not shown distributes the primary hot water leaving the exchanger through the conduit 16, ie towards the hot start. fage 17, with return through the conduit 20 -or towards a short circuit 18, a pump 19 being interposed on the common conduit 21 returning to the exchanger.
  • the domestic water circuit supplied by the inlet tube 22 supplies water to the draw-off points via the domestic water departure tube 23.
  • an igniter 24 supplies a spark train to the pilot 25.
  • the purpose of the microprocessor-based regulation system is to control terminal members as a function of information collected by sensors.
  • the microprocessor control unit 26 receives for this purpose information from temperature sensors such as the room thermostat 27 mounted outside the device and the heating water return sensor 28 mounted on the duct 21.
  • the information are also received from an air flow sensor 29 mounted on the air intake orifice 11 inside the sealed enclosure from the distributor housing 10.
  • These sensors except the room thermostat , deliver an analog signal (variable voltage depending on the quantity to be measured) which must be converted into digital values which can be assimilated by the microprocessor.
  • other information is provided by a sensor 30 mounted on the motor 7 of the exhaust fan.
  • Said sensor detects the passage of four magnets fixed on the end of the motor shaft or of a notched disc followed by an optoelectric reader and delivers a digital signal whose frequency is proportional to the speed of the motor.
  • information on the drawing of sanitary water is provided by a drawing contact 31 disposed at the level of the reversing valve 15.
  • a contact linked to the igniter 24 provides the housing 26 with information on the ignition cycle.
  • the terminal members capable of being thus controlled by the regulation system are the gas solenoid valve 12, the water circulation pump 19, the igniter 24, and in the sealed enclosure of the device the exhaust fan. 6.
  • a first initialization sequence aims to "teach" the microprocessor the context in which it will regulate the boiler. This sequence is as follows: - the gas inlet and the igniter 24 are inhibited; - The exhaust fan 6 is put into operation at maximum speed then the microprocessor thanks to the sensor 29 comes to read the value of the air flow rate which passes through the orifice 11 of the distributor box 10 to the interior chamber of the device. This value must be equal to a determined value below which there would be a failure to install and stop programming. If this value is therefore normal, it is stored in memory after calculation, as being the minimum flow value corresponding to the full flow rate of the exhaust fan. This fan is then passed to 50% of its maximum speed and a new flow measurement is carried out. The memorized value then represents the minimum value of air flow for the small flow of fan 6. This is then stopped; the igniter 24 is energized to light the pilot 25. The release of the push button at the circuit breaker box 14 completes this initialization sequence.
  • the purpose of these two flow measurements is to calibrate the air flow sensor so as to eliminate the influence of the position of the suction cup.
  • the microprocessor periodically reads the state of the temperature sensors at room thermostat 27 and at draw-off contact 31.
  • the circulation pump 19 remains stopped and the fan d Extraction only starts very intermittently (for example 15 seconds every 5 minutes) and at reduced speed (50% of nominal speed) to ensure the air supply to the pilot.
  • the circulation pump 19 Upon receipt of an order from the room thermostat 27, that is to say as soon as the temperature sensed is below the predetermined threshold, and there is a demand for calories, the circulation pump 19 starts working ; the gas inlet by the solenoid valve 12 and the speed of the exhaust fan 6 are then modulated by the microprocessor 26 in order to ensure a constant proportionality of the air-gas mixture and to maintain a water return temperature of heating via line 20, equal to the set temperature adjusted by the user since the power is adaptable to the needs of the installation. In the event of burner 5 stopping, it will not be able to re-ignite before a certain delay (of the order of one minute for example) in order to avoid too repeated cycles of switching on and off.
  • the pump and the exhaust fan will be kept in operation for some time (for example 45 seconds) after the gas has stopped and the ignition of the burner will only take place through a small phase. flow to ensure silent ignition.
  • the air flow sensor 29 informs the microprocessor 26 of the air flow admitted into the device through the orifice 11. If the latter is insufficient to ensure the correct combustion of the gas introduced, the gas flow will then be reduced to reach the mixture suitable for correct combustion.
  • the microprocessor Upon receipt of an order from the drawing contact 31, that is to say as soon as there is a call for calories when the user draws water, because this call has priority over during heating, the microprocessor then regulates the primary circuit (16, 21) that the reversing valve 15 distributes via the short circuit 18. This regulation of a principle analogous to that of heating operation is done at a fixed setpoint value allowing '' obtain a satisfactory temperature on the secondary drawing-off circuit.
  • This microprocessor-based control system also provides a test program making it possible to verify the operation of the control card outside the boiler by simulating the commands sent to the terminal members as a function of information applied to the inputs.
