Definitions

  • the invention relates to a method for controlling a heating system with a primary heat exchanger that can be heated by a burner and to the flow of the primary heat exchanger via a three-way valve connected to the heating water circulation lines for heating a secondary heat exchanger arranged in a domestic hot water tank and at least one radiator, with a first temperature sensor in one for the secondary heat exchanger of the hot water tank leading branch of the flow line of the primary heat exchanger and a second temperature sensor are arranged in or on the hot water tank or its tap line and to control the three-way valve and a valve regulating the fuel supply to the burner, the two temperature sensors via signal lines to a common, via control lines with which the fuel supply to The burner regulating valve and the regulator connected to the three-way valve are connected.
  • this process water temperature is also dependent on the respective draw-off quantity and on the temperature of the cold water flowing from the supply line to the storage tank.
  • the object of the invention is therefore to provide a method in which there is a guarantee of a constant, arbitrarily selectable hot water temperature which is independent of the respective cold water temperature and the respective tap quantity, in particular when the system is operated by means of a single-stage burner.
  • the object is achieved in that, in the case of hot water tapping or recharging, the output of the burner is regulated as a function of the temperature detected by the first temperature sensor and its deviation from a target value, this target value depending on the difference between a set hot water temperature and the temperature measured by the second temperature sensor.
  • a preselectable outlet temperature of the domestic water at the tap can be guaranteed regardless of the temperature of the incoming cold water and regardless of the respective tap quantity.
  • a flow switch can be arranged in its cold water supply line or in its tap line, which starts the burner regardless of the instantaneous temperature of the storage water. If the burner is equipped with a combustion air or exhaust gas blower, the blower is operated continuously from the first burner cycle until the end of the tap cycle in order to achieve a delay-free cycle of the burner and thus to limit the fluctuations in the flow temperature to a minimum.
  • the water heating system comprises a burner that heats a water-carrying heat exchanger 1, preferably a gas burner 2 Fuel gas is supplied via a gas supply line 3 and a valve 4 regulating the gas supply.
  • This primary heat exchanger 1 emits heating water via a supply line 5 and is connected to a return line 6, which returns the cooled heating water.
  • a three-way valve 7 is arranged, which either opens the way to a heating circuit 8 in which there is at least one heating element 9, or - during the continuous or recharging operation - the flow flowing from the primary heat exchanger the way to a secondary heat exchanger 11 of a hot water tank 12 via the circulation line 10 opens.
  • a tap line 13 with at least one tap valve 14 and a tap point 15 starts from the hot water tank 12.
  • the hot water tank 12 is supplied with cold water from the supply line 16.
  • the flow switch 17 can be arranged, which is connected to the controller 22 via a signal line 25 and starts the continuous operation of the domestic hot water tank 12 as soon as a tap is taken.
  • the system comprises at least two temperature sensors, namely a temperature sensor 18 in the flow line 10 of the heating water heating the hot water tank 12 and a temperature sensor 19 arranged in or on this hot water tank 12 itself or on the tap line 13.
  • temperature sensors 18 and 19 are connected via signal lines 20 and 21 to a common controller 22 which controls the valve 4 regulating the fuel supply to the burner 2 via the control line 23 and the three-way valve 7 via the control line 24, depending on the two of them measured values transmitted by the temperature sensors 18 and 19.
  • the controller 22 is assigned a preselection device 26 for the desired hot water temperature and connected to it via a control line 27.
  • Figure 2 shows the head area of the domestic hot water tank 12 on a larger scale, together with the connection of the hot water circulating line 10 and the outlet of the tap line 13 and with part of the coil forming the secondary heat exchanger 11.
  • the output of the burner 2 is regulated as a function of the temperature detected by the temperature sensor 18 in the flow line 10 and its deviation from a predetermined target value.
  • This target value is formed by the controller 22 as a function of the difference between the hot water temperature set on the preselection device 26 and the temperature measured on the sensor 19.
  • the target value for the flow temperature is reduced, thus ensuring a hot water temperature that is independent of the cold water temperature and the flow rate (draw-off volume).
  • this temperature sensor 19 also takes over the function of a mechanical thermostat that regulates the temperature of the storage water and starts or ends a recharging of the domestic water storage.
