Definitions

  • the invention relates to a device for heating circulating heating water and process water.
  • heat exchangers which can be used for combined heating systems (heating, domestic water preparation).
  • a domestic water heat exchanger around which the heating water flows is provided within the heating heat exchanger.
  • This improves, among other things, heat transfer processes compared to a secondary heat exchanger for domestic water heating.
  • Combined heating systems with separate heat exchangers for domestic hot water preparation and for heating without a separate domestic hot water tank are also known (AT 2489/90), in which the start-up phase of domestic hot water preparation is improved in that a heating water tank is provided in an internal heating circuit.
  • the required final hot water temperature is reached faster than in the heating system in which the heating water buffer volume in the heating water tank is directly coupled to the hot water preparation.
  • the heating water volume in the heating water reservoir can be selected to be smaller and / or the temperature can be kept at a lower temperature level during the downtimes.
  • the heating water reservoir located in an internal heating circuit On or off. If it is switched off during the night (downtime), the heating water in the heating water tank does not need to be kept at a high temperature level; if hot water is nevertheless required, the hot water can then be provided in a conventional manner without involving the heating water tank.
  • the control device which is connected to the inner heating circuit for the optional switching on or off of the heating water store is advantageously designed as a four-way valve, which at the same time serves to provide hot water for the heating and / or the supply of process water.
  • control device for switching the heating water reservoir on or off is the arrangement of a controllable bypass channel directly in the heating water reservoir.
  • a valve arranged in the bypass duct the heating water in the heating water tank can either be included in the internal heating circuit or not.
  • the heating water storage tank is designed as a side of an expansion vessel which carries heating water and is a necessary part of every heating system.
  • FIG. 1 shows a schematically represented device for heating heating water and process water, a second embodiment of the device being shown in dashed lines.
  • Figures 2 and 3 show an enlarged section of the device according to the invention in a third embodiment in two different switching states.
  • a device for heating circulating heating water and process water has a heating heat exchanger 10 arranged in a heating circuit and through which the heating water flows, the fins 11 of which are directly affected by the combustion gases of a burner 12 are acted upon.
  • the heating heat exchanger 10 supplies a heating device, for example a radiator 18, arranged between a forward section 14 and a return section 16 of the heating circuit, with a circulation pump 20 for conveying the circulating heating water being arranged in the return section 16.
  • a hot water heat exchanger 22 which is arranged in the heating heat exchanger 10 and around which the heating water flows is provided.
  • a hot water supply device connected to the hot water heat exchanger 22 feeds one or more tapping points with hot water via a cold water connection 24, a water switch 26 and a hot water connection 28.
  • a three-way valve 30 arranged in the return section 16 of the heating circuit 14, 16 and a reversing line 32 of the heating circuit 14, 16 separated.
  • a heating water reservoir 34 is arranged in a reversing line 32 connecting the forward section 14 and the return section 16 of the heating circuit, bypassing all or part of the heating device 18.
  • the heating circuit which leads from the heating heat exchanger 10 via the flow section 14, changeover line 32 and heating water tank 34, three-way valve 30, return section 16 and pump 20 back to the heating heat exchanger 10, is referred to below as the inner heating circuit 34, while the heating circuit, that of Heater heat exchanger 10 via flow section 14, radiator 18 and return section 16 back to Heater heat exchanger 10 leads, hereinafter referred to as the outer heating circuit 38.
  • the device for heating circulating heating water and process water works in the following way:
  • the burner 12 is ignited and the outer heating circuit 38 is activated with the aid of the circulation pump 20, the heating elements 18 arranged in the outer heating circuit 38 being charged with heating water.
  • the command for hot water heating is given.
  • the burner 12 is ignited at a certain differential pressure generated by the water switch 26 and the circulation pump 20 is switched on.
  • the three-way valve 30 is switched so that the heating water circulates in the inner heating circuit 36. Due to the heat transfer from the circulating heating water to the hot water, 28 hot water can be drawn from the hot water connection.
  • the heating heat exchanger 10 and the heating water located in the inner heating circuit 36 cool down relatively quickly, so that if a service water request were made, it would take some time until hot service water could be drawn off.
  • FIGS. 2 and 3 show an arrangement in which, instead of the four-way valve 40 and the control line 42 for the optional activation or deactivation of the heating water reservoir 34, a bypass duct 46 provided with a valve 44 is arranged directly in the heating water reservoir 34.
  • the bypass duct 46 connected to the changeover line 32 of the inner heating circuit 36 draws when the valve 44 is closed (FIG. 2) Via auxiliary openings 48 arranged on the bypass duct 46, the heating water located in the heating water reservoir 34 is also introduced into the inner heating circuit 36. If the bypass channel 46 is opened by the valve 44 (FIG. 3), the heating water in the heating water reservoir 34 is not included in the inner heating circuit 36 if the valve 44 and the secondary openings 48 are suitably dimensioned.
  • the heating system is designed so that in this position there are no pressure differences between the heating water flowing in the inner heating circuit 36 and the heating water located in the heating water storage 34, so that practically no heating water flows through the secondary openings 48 of the bypass duct 46 from the heating water storage 34 into the inner heating circuit 36 can flow.
  • the heating water reservoir 34 consists of a housing half 50 which carries the heating water and is separated from a housing half 52 which holds a gas volume.
  • An elastic membrane 54 is arranged between the two housing halves 50, 52, so that the volume changes occurring in the entire heating device due to temperature fluctuations can be compensated for.
  • the heating water reservoir 34 which is then simultaneously designed as an expansion vessel, contributes to a particularly compact design of the heating device.
