Definitions

  • the invention relates to a continuous heater for a Nutz sometimeskeit with a storage container which receives a heat-emitting liquid.
  • Such continuous heaters are known.
  • the term means that the use liquid is heated by flowing inside through the tubes of a heat exchanger, which is heated from the outside.
  • the useful liquid is therefore not heated by the fact that a larger reservoir of the liquid is constantly heated.
  • a practical application for the continuous heater according to the invention is the provision of utility or service water in residential buildings.
  • the service water is needed there for the purposes of the household, the kitchen and in the bath for bathing or showering.
  • the special feature of domestic water abstraction is that at irregular intervals highly fluctuating amounts of hot water are to be taken.
  • the available amount of removable liquid is often insufficient.
  • FIG DE 41 42 488 A1 An example of a prior art continuous-flow heater is shown in FIG DE 41 42 488 A1 ,
  • the heating of the useful liquid is combined with the heating of the heating water.
  • the exhaust gases of a gas burner flow through a coiled tube, which is formed from a coaxial tube.
  • a storage container for the useful liquid is connected downstream of the coaxial tube heat exchanger.
  • This storage container is a working according to the displacement principle stratified storage; the useful liquid is conveyed by a charge pump in circulation through the coaxial heat exchanger and the stratified storage. The removal of the useful liquid takes place from the stratified storage.
  • FIG. 1 Another embodiment shows a continuous-flow heater according to the DE 198 07 657 C1 ,
  • a heat exchanger made of coiled tubes is arranged in a storage container.
  • the storage container is filled with water, which is heated by various means.
  • a built-in or adjacent boiler can serve.
  • a solar system or a heat pump can be used to heat the storage water.
  • No own storage is provided for the useful liquid.
  • the storage tank In order for the heat capacity of the storage water is sufficient to always heat a sufficient amount of liquid, the storage tank must be sufficiently large, and it must be possible to heat it up briefly strong.
  • a large-sized storage heater is used to hold the service or use liquid.
  • a heat exchanger made of coiled pipes is also installed in the storage container.
  • the tubes are arranged in the manner of a cylindrical thread.
  • a first section of the heat exchanger is provided with coaxial tubes, wherein an inner tube is arranged in an outer tube.
  • an inner tube enters the cold liquid and enters the inside of the storage container at the end of the inner tube.
  • a heat-emitting liquid is performed, which initially fills the entire cross-section of the outer tube and is then guided in the annular space between the outer and inner tube.
  • the heat-emitting liquid flows in countercurrent to the use liquid.
  • the incoming heat-emitting liquid thus first heats the already in the storage container used useful liquid and then in heat exchange with the inner tube of the coaxial also directly the incoming cold liquid.
  • the heat-releasing liquid becomes thereby already well utilized; but it is still a very large storage tank for the liquid used required.
  • a temperature influencing of the respective other heat-emitting medium is achieved via the fresh water flowing in the annular space of the co-axial heat exchanger. It may happen that an overheated coolant by heat transfer to the fresh water, which further warms the carrier medium in the interior.
  • DE 195 35 265 C1 shows a located in a container of a hot water heater two-chamber heat exchanger, which is formed of two co-axial helical coiled tubes.
  • a useful liquid is displaced into an inner tube of the two-chamber heat exchanger by supplying fresh water in the container, and flows through an outflow, which is connected to the inner tube, from the hot water heater.
  • fresh water flows countercurrently into the container.
  • a disadvantage of this device is that the entire water in the container must be kept at a certain temperature level, so that water can be removed from the container a certain temperature.
  • the invention has for its object to provide a continuous flow heater for a Nutz gallkeit with a storage container which receives a heat-emitting liquid, which can be dispensed by improving the heat transfer to a storage for the Nutz alloykeit.
  • a continuous flow heater for a Nutz specialkeit with a storage container which receives a heat-releasing liquid, and with a Koaxialrohr heat exchanger, which is arranged in the storage container and consists of a coiled outer tube and an inner tube located therein, wherein the inner tube is flowed through by the same heat-emitting liquid contained in the storage container, while the ring cross-section between the inner and outer tube is flowed through by the Nutzenberg deviskeit and the inner and outer tube after liquid management and connections are completely separated.
  • the useful liquid flowing through the coaxial-tube heat exchanger is simultaneously heated from the inside and from the outside.
  • the heating from inside is done by the heat-emitting liquid flowing through the inner tube of the coaxial tube.
  • the heating from the outside is carried out by the heat-releasing liquid in the storage container.
  • the heat transfer can make very cheap, and also the storage container for the heat-emitting liquid must not be excessively large.
  • the embodiment of the invention also has the advantage that not a storage container for the useful liquid (service water), in which the liquid is more often, must be kept clean and germ-free, but only the annulus of the coaxial heat exchanger, which is easier to accomplish with the usual technical and chemical means.
