Definitions

  • the allocation of the fan speed depending on the exhaust gas or supply air temperature is determined by a compensation characteristic stored in a control unit. This is composed of empirical values that are supplemented by parameters determined by the heater itself before the start of the first heating process, such as the internal flow resistance. This ensures that a fan speed required in accordance with the compensation is assigned to each exhaust gas or supply air temperature during operation.
  • FIG. 1 shows the heating device according to the invention for carrying out the control method according to the invention
  • FIG. 2 shows a compensation characteristic from which the fan speed required for a constant supply air mass flow rate can be determined as a function of the exhaust gas temperature or the supply air temperature
  • FIG. 3 shows a functional sequence plotted over time After the heater has been switched on, it shows a) the signal for the heat request, b) the fan speed, c) the signal for the ignition, d) the condition of a pressure cell and e) the gas supply.
  • the exhaust gas 27 which is produced during combustion is released into the open via the exhaust line 26.
  • the supply air line 16 and the exhaust gas line 26 run coaxially to one another and are connected to the environment via an opening 40 in the housing 10.
  • the temperature of the fan 24 changes conveyed exhaust gas volume flow.
  • the exhaust gas temperature changes as a function of the change in the supply temperature of the heating water in the heat exchanger 38 and as a function of the device state from which the start was made (cold / warm).
  • the temperature of the exhaust gas 27 is also influenced by temperature changes in the supply air 17.
  • General heating of the heater, as well as the coaxial routing of the supply air line 16 to the exhaust gas line 26 and the fan 24 arranged for cooling in the supply air line 16 bring about a temperature increase in the supply air and thus also an increase in the temperature of the exhaust gas 27 during combustion.
  • exhaust gas 27, that is, the fan is running there is combustion.
  • the designation nominal speed means that the blower works with 100% output taking into account the necessary compensation of the speed due to the different exhaust gas temperatures.
  • the fan 24 is started up first when a heat is requested via the control unit 42.
  • the exhaust air volume flow conveyed by the fan 24 corresponds to a specific supply air volume flow.
  • the difference in the pressures detected by the control lines 50, 52 in the channel-shaped line 18 is a measure of the delivered supply air volume flow.
  • the contacts of the pressure cell 54 attached between the control lines 50, 52 close at a point in time t1.
  • the speed of the fan 24 which in this case corresponds to 80% of the nominal speed of the fan 24 and the temperature by the Sensor 46 detected exhaust air 27 stored in the control unit 42.
  • the speed of the fan 24 is detected with the aid of a sensor 44 attached to the fan 24.
  • the sensor 46 is arranged on the inside of the housing 25 of the fan 24. He is thus directly exposed to the temperature of the exhaust gas 27 being conveyed.
  • PTC resistors, thermocouples or NTC resistors can be used as temperature sensors. The latter have the advantage that they have a relatively large linear characteristic range.
  • the sensor 46 consists of two NTC resistors with different resistance values, preferably 10 k ⁇ for a temperature range from 0 ° to 90 ° C and 100 k ⁇ for a temperature range from 90 ° C to 200 ° C.
  • the fan 24 ' is arranged in the supply air duct 18, the combustion chamber 36 and the exhaust gas-carrying parts must be designed to be tight.
  • the control procedure is just as little on Restricted gas heaters, but can in principle also be used for heaters with other energy sources, such as oil.
