Definitions

  • the invention relates to a heater for heating and heating of process water with a circulating in a circulating heat transfer medium.
  • a heater is known from the patent application DE 10 2007 029 971 , Such a heater comprises a burner for generating heat, a primary heat exchanger for transmitting the heat generated by the burner to the heat transfer medium and a connection for the flow and the return of a heating circuit to which an external heat sink, for example in the form of one or more radiators is connected ,
  • a generic heater comprises a secondary heat exchanger for transferring the heat from the heat transfer medium to the hot water to be heated.
  • the external heat sink and the secondary heat exchanger in the heating circuit are connected in parallel.
  • the heat transfer medium generated by the burner can be passed either through the secondary heat exchanger or through the external heat sink.
  • a heater according to the preamble of claim 1 is known from the patent DE102 44 339 A1 known.
  • the heating water storage tank is heated by a low-temperature heating device, for example a solar system or geothermal heat, and / or by a high-temperature heating device, for example a burner.
  • the heating water storage tank in the case of heating by the high-temperature heater by a three-way valve hydraulically downstream of the external heat sink, in usually the radiators of the building to be heated to be connected in series. With sufficient energy through the low-temperature heating or low heat demand of the heat sink, the heat demand of the heat sink can be covered from the Schuungswasser notes with switched off high-temperature heating. Since the heating water storage tank sheathes the process water storage tank, a heat exchanger takes place between the two storage tanks.
  • the degree of utilization or the efficiency of the heat transfer depends on the temperature level of the heat transfer medium flowing into the primary heat exchanger.
  • the condensing technology also results in efficiency advantages at a low temperature of the heat transfer medium by a higher condensation rate.
  • the secondary heat exchanger is arranged as part of a heating system so that in operation with a heat transfer medium filled circuit and running pump, the heat transfer medium is first heated in a first valve position in the primary heat exchanger, then passed through the heat sink and then passed through the secondary heat exchanger.
  • heat transfer medium is first heated in a first valve position in the primary heat exchanger, then passed through the heat sink and then passed through the secondary heat exchanger.
  • the residual heat of the return of the heat sink can be used advantageously, on the other hand, the temperature of the heat transfer medium compared to the prior art can be further lowered, which improves the efficiency of heat transfer in the primary heat exchanger, since the condensation rate increases in a heater with condensing technology.
  • Another advantage is that the minimum heat output that can be delivered to the heat sink is reduced. For reasons relating to the stability of the mixture formation for the burner, the ratio between maximum and minimum burner output is limited. The possibility of extracting heat from the heat transfer medium and using it for the process water increases the ratio between maximum and minimum power delivered to the heat sink.
  • valve is transferred to a second valve position, so that the output of the burner is available exclusively for hot water heating.
  • FIG. 1 shows the diagram of a heating system with a heater 1 according to the invention.
  • the heater 1 comprises the burner 2, the heat in the primary heat exchanger 3 to a heat transfer medium, usually water transfers.
  • the heat transfer medium is circulated by means of the pump 6.
  • the valve 7 can in a first Valve position are switched so that the heat transfer medium circulates in the valve flow direction 18.
  • the heat transfer medium will first flow through the heat sink 17, which are connected to the connections for flow 9 and return 10.
  • the heat sink 17 is, for example, radiators, floor heating et cetera for heating a building. In the heat sink 17, the heat transfer medium cools down. Thereafter, the heat transfer medium flows through the secondary heat exchanger 4 and gives off more heat to the hot water.
  • the pump 11 circulates the service water stored in a stratified storage 14 via the connections 12, 13 and heats it in the secondary heat exchanger 4.
  • the stratified storage 14 has a cold water inlet 16 for supplying cold process water and a hot water connection 15 for the removal of heated process water. Due to the different density of hot and cold water forms within the stratified storage 14, a temperature stratification. In extreme cases, the temperature in the lower region of the stratified storage 14 can assume the temperature of the water flowing in via the cold water inlet 16. This may be, for example, 10 ° C, so that the secondary heat exchanger 4 is supplied via the terminal 13 up to 10 ° C cold hot water.
  • the circulating 5 circulating heat transfer medium after it has left the heat sink 17, additionally cooled, so that the primary heat exchanger 3, a colder heat transfer medium flows than is the case with heaters according to the prior art.
  • a higher efficiency of the heat transfer in the primary heat exchanger 3 is achieved or a condensing effect with a higher condensation rate is achieved and the modulation range of the heater is expanded with respect to the heat sink 17.
  • the secondary heat exchanger 4 would lead to a heat extraction of the process water.
  • the pump 11 can be switched off in such cases in the valve flow direction of the first valve position 18.
  • valve position between the first 18 and the second valve position 19. This serves to increase the ratio between maximum and minimum power delivered to the heat sink.
  • heater 1 Another advantage of the heater 1 according to the invention is that the same components can be used for all components 2, 3, 4, 6, 7, as they are used for heating devices according to the prior art. This has advantages in terms of costs and stocking spare parts.
  • modular heaters can be produced, which can be configured by another piping of the circuit 5 either as conventional heaters according to the prior art or as heaters 1 according to the invention.
