Definitions

  • the invention relates to a device for heating of circulating heating water and process water.
  • heat exchangers for combined Heating systems (heating, hot water preparation) can be used. It is within the Heating heat exchanger a flowed around by the heating water Domestic hot water heat exchanger provided. Thereby are under other heat transfer processes versus one Secondary heat exchanger for hot water preparation improved.
  • From document GB-2 262 593 A is a device for Heating of circulating heating water and process water known with a heating heat exchanger that has a heating circuit supplied with hot water.
  • the heating circuit is provided in advance with a control device that the Heating circuit via a changeover line into an inner one Heating circuit and an outer, provided with radiators Circuit separates.
  • the buffer tank and the hot water tank are each surrounded with bypass lines that serve the purpose that the Efficiency for supplying hot water to the domestic water pipe is increased.
  • a simplified version is given in document AT 398 831 B.
  • a heater with an internal heating circuit and an outer heating circuit, with a buffer memory in A changeover line is integrated, one from the heating heat exchanger separately arranged domestic water heat exchanger supplied with heating water.
  • the required Final hot water temperature reached faster than with Heating system which is in the heating water tank located heating water buffer volume directly to the Process water preparation is coupled.
  • Heating system which is in the heating water tank located heating water buffer volume directly to the Process water preparation is coupled.
  • the arrangement according to the invention can do this in the heating water tank heating water volume can be selected smaller and / or the temperature during the downtimes be kept at a lower temperature level.
  • the for switching on or off the Heating water storage connected to the internal heating circuit Control device is advantageously a four-way valve trained that at the same time providing Hot water for heating and / or hot water supply serves.
  • control device for switching the heating water tank on or off is the Arrangement of a controllable bypass channel directly in the Heating water tank.
  • the valve can be the heating water in the heating water tank optionally included in the inner heating circuit or not.
  • FIG. 1 shows a schematically represented Device for heating heating water and Process water, being a second embodiment of the Device is shown in dashed lines.
  • Figures 2 and 3 show an enlarged section of the invention Device in a third embodiment in two different switching states.
  • An exemplary device for heating circulating heating water and process water has an in arranged in a heating circuit and from the heating water flowed through the heat exchanger 10, the fins 11 of the combustion gases of a burner 12 directly are acted upon.
  • the heating heat exchanger 10 supplies one between a lead section 14 and one Return section 16 of the heating circuit arranged Heating device, e.g. a radiator 18 with Heating water, in the return section 16 a Circulation pump 20 for conveying the circulating heating water is arranged.
  • a Circulation pump 20 for conveying the circulating heating water is arranged.
  • an im Heating heat exchanger 10 arranged and from the heating water flow around hot water heat exchanger 22 is provided.
  • Process water supply device feeds one or more Dispensing points via a cold water connection 24, one Water switch 26 and a hot water connection 28 with Process water.
  • Heating water to the in the domestic water heat exchanger 22 flowing hot water can take place is via an in Return section 16 of the heating circuit 14, 16 arranged three-way valve 30 and one Changeover line 32 of the heating circuit 14, 16 separated.
  • a heating water tank 34 is arranged in one the forward section 14 and the return section 16 of the heating circuit connecting reversing line 32 is bypassing all or part of the Heating device 18, a heating water tank 34 is arranged.
  • the device for heating circulating heating water and process water works in the following way:
  • the burner 12 is ignited and with With the help of the circulation pump 20, the outer heating circuit 38 activated, the in the outer heating circuit 38th arranged radiator 18 can be charged with heating water.
  • the hot water device becomes the command DHW heating is given.
  • the burner 12 is at one determined differential pressure generated by the water switch 26 ignited and the circulation pump 20 turned on.
  • the three-way valve 30 is switched so that the heating water in inner heating circuit 36 circulates. Through the heat transfer from the circulating heating water to the hot water can on Hot water connection 28 hot water can be removed.
  • Heating water tank 34 the heating water volume over the internal heating circuit 36 at a certain temperature, for example 70 ° C, ensures that too after longer pauses in the heating heat exchanger 10 and the hot water heat exchanger 22 by the from Heating water storage 34 removed heating water immediately be heated up and warm by heat transfer Domestic water can be removed. A few seconds after The hot combustion gases have hot water start acted fins 11 of the heat exchanger 10th reached their operating temperature, so now through primarily the combustion heat supplied by the burner 12 Domestic water is heated. This is the hot water supply no longer from the heat potential of the heating water dependent in the heating water tank 34, so that be Storage volume can be chosen very small.
  • Heating water tank 34 from the inner heating circuit 36 separate. It only gets in the morning Heating water tank 34 back to the inner Heating water circuit 36 connected and be Storage volume on the inner heating circuit 36 on the preset temperature brought. Through the optional or switching off can further reduce energy costs become.
  • Figures 2 and 3 show an arrangement in which instead of the four-way valve 40 and the control line 42 for the optionally switch on or off the heating water tank 34 with a valve 44 bypass channel 46 directly in the Heating water tank 34 is arranged.
  • the one with the Reversal line 32 of the inner heating circuit 36 connected Bypass channel 46 relates when valve 44 is closed (FIG. 2) via arranged on the bypass channel 46 secondary openings 48 in Heating water storage 34 located heating water in the inner heating circuit 36.
  • the bypass channel 46 through the valve 44 is opened (Fig. 3), so when appropriate Dimensioning of the valve 44 and the secondary openings 48 that in the heating water storage 34 heating water is not in the inner heating circuit 36 included.
  • the heating system is designed so that in this position none Differences in pressure between that in the inner heating circuit 36 flowing heating water and that in the heating water tank 34 located heating water exist, so that practically no Heating water from the secondary openings 48 of the bypass duct 46 the heating water reservoir 34 in the inner heating circuit 36 can flow.
  • the heating water tank 34 consists of a heating water leading housing half 50 by a gas volume receiving housing half 52 is separated. Between the two Housing halves 50, 52 is an elastic membrane 54 arranged so that in the entire heater volume changes due to Temperature fluctuations can be compensated. The one then trained at the same time as an expansion vessel Heating water tank 34 contributes to a particularly compact Construction of the heater.
  • the inner heating circuit 36 and the outer heating circuit 38 can be fed with heating water at the same time. It makes sense such a rule, especially if the Outside temperatures are very low and at the same time Domestic hot water supply to the radiators 18 necessary is.
