Definitions

  • the invention relates to a gas boiler regulating device using a circulation pump which supplies a circuit of radiators from a heat exchanger, a device by which a stable operation of the appliance is ensured, even for requirements lower than the minimum power.
  • regulating devices allow the regulation of the water temperature according to the size of the installation and the power demanded. .
  • it must permanently receive information on the temperature of the water passing through the heat exchanger and thus be able, depending on the flow rate, to interpret these indications in the sense of a command to open or gradually close the gas supply to the burner.
  • One or more temperature sensors are then placed at the inlet or at the outlet of the exchanger, for detecting respectively the temperature of the water returning from the radiators or that of the hot water supplied by the exchanger, as described in DE-C2 3538 934.
  • the subject of the invention is a new regulation which eliminates these drawbacks, which combines the advantages of each of the regulations on the departure and on the return while avoiding placing a temperature sensor, both on the departure and on the return of the circuit that is to say downstream and upstream of the heat exchanger.
  • the invention therefore relates to a device for regulating a gas boiler comprising a heat exchanger heated by a gas burner supplied by a solenoid valve, said solenoid valve being itself actuated by a microprocessor regulating device, and comprising a hot water starting circuit leaving said exchanger to supply radiators under the action of a circulation pump and returning to said exchanger, a temperature sensor being provided on the starting pipe at the outlet of the exchanger, device according to which said sensor is a single sensor arranged in connection with an integrator and a regulating device for providing indications on the actual temperature of the hot water on the flow circuit before the burner stops and for deducing the temperature that 'would have the return water on the return circuit upstream of the exchanger from an indication of the water temperature on the circuit flow, taken after the burner has stopped and after a determined period of circulation of unheated water in the circuits, and according to which the temperature detected by the sensor is applied to the integrator which calculates the temperature difference between the water from the outgoing circuit and that from the return circuit.
  • a gas boiler 1 such as a heating body 2 constituting the heat exchanger, heated by a burner 3, itself supplied with gas by means of a solenoid valve. 4.
  • a circuit 5 for the start of hot water supplied by the exchanger feeds a plurality of radiators 6, the water returning to the exchanger by a return circuit 7 in which there is a circulation pump 8.
  • a temperature sensor 9 is placed on the circuit 5 just downstream of the exchanger 2.
  • the solenoid valve 4 is actuated by a microprocessor-based regulating device 10 to which the temperature detected by the sensor 9 is applied and which controls the gas inlet 14 to the solenoid valve 4 via a current generator 11.
  • a potentiometer 12 for adjusting the set value is also associated with the gas control 14.
  • the temperature detected is also applied to an integrator 13 which calculates the value ⁇ at switch-off, the ⁇ being the difference between the temperature of the starting water noted by the sensor 9 and that of the return water as it enters the boiler through the return circuit 7.
  • the water temperature upstream and downstream of the exchanger is identical.
  • a set temperature tc displayed by the potentiometer 12 is a desired temperature t1 and in the case where the demand for calories is less than the small power, when the boiler starts up, the temperature t1, increased by a differential value, for example of 2 °, will be reached more or less quickly depending on the installation and the water flow, therefore the circulation delay time, and the boiler will stop.
  • the pump 8 during the determined duration of the post-purge after the burner has stopped, continuing to circulate the water in the circuit between the flow and the return to the exchanger, the temperature will, during this period of time, go from a temperature t1 + 2 ° to a temperature t2.
  • the sensor 9 At the end of this post-scanning period, the sensor 9 will provide a temperature value t2 ⁇ t1, the ⁇ between these temperatures then being given by the difference (t1 + 2 °) - t2 this to the evolution of the temperature back close.
