Definitions

  • the invention relates to a device for heating domestic water, consisting of a domestic hot water tank and one in the domestic hot water tank arranged heat exchanger, the at least one with the Hot water in the hot water tank directly in the heat exchange has a standing pipe coil with several turns for a heating medium, which extend over the bottom of the domestic hot water tank Area.
  • a heat exchanger (FR-B 2 301 795) Form flow channels between two profiled sheet metal walls, which in an annular area are bent in spiral turns. The between the flow channels formed in parallel with the sheet metal walls are therefore superimposed on what is related to the vertical between the individual turns of the sheet metal walls Flow paths for the liquid to be heated a vertical flow this liquid supports and thus in the case of domestic water heating destroys the stratification of the process water. Besides, it is due to the flow channels lying one on top of the other determining height of the heat exchanger not possible, the storage volume of the domestic hot water tank as usable volume. Additional to that, that in the area of the upper flow channels for the heating medium, the process water already has a higher temperature, so that in this area Heat transfer from the heating medium to the domestic water is impaired.
  • the invention is therefore based on the object of avoiding these deficiencies and a device for heating domestic water of the aforementioned Art to improve so that essentially the entire storage volume of the domestic hot water tank is available as usable volume and a good heat transfer from the heating medium to the domestic water ensured becomes.
  • the invention solves the problem in that the at least essentially Windings of the pipe coil distributed over the entire floor area form only one turn layer in height.
  • the overall height of the heat exchanger essentially on the cross-sectional dimensions of the pipe coil forming Pipe are limited so that with an arrangement of the heat exchanger immediately above the bottom of the domestic hot water tank Usable volume essentially the storage volume of the domestic hot water tank corresponds.
  • there is a particularly good use of heat of the heating medium because of the Heat exchanger according to its arrangement in an over the bottom of the domestic hot water tank extending surface can always be in the area of cold water.
  • the coils of the pipe coil are in one over the other
  • the coils of the surface formed by the coil do not need to be parallel to the ground To be cross-sectional level.
  • the coil from a constricted in terms of its cross-section from two opposite sides, upright pipe.
  • This "dragonfly-like" cross-sectional shape increases the heat exchange area in relation to the volume of the heating medium and due to the upright arrangement of these pipes, one is necessary for heat transfer advantageous water flow between the pipe coils.
  • the laying of the coil in the form of a spiral can be due to thermal expansion or external influences to undesirable shifts of the individual Lead turns against each other.
  • To such shifts in turns can avoid the turns of the spiral coil in a holder are held with star-shaped bracket arms that directly with the Domestic hot water tank, for example by welding, can be connected.
  • the device shown for heating domestic water consists essentially for the sake of clarity only shown in the floor area Domestic hot water tank 1 and one arranged in this domestic hot water tank Heat exchanger 2, which is located directly above the drain line 3 connected bottom 4 of the domestic hot water tank 1 is arranged.
  • This Heat exchanger 2 is formed by a coil 5, which has several turns 6 is laid in the form of a single-layer spiral, which extends over the bottom in a extending cross-sectional plane.
  • These turns 6 are from a bracket 7 added, which consists of star-shaped bracket arms 8, in which Slots 9 are provided for receiving the individual turns 6.
  • For installing the heat exchanger 2 in the hot water tank 1 only need the bracket arms 8 on the Wall of the domestic hot water tank 1 to be welded.
  • the coil 5 was made from an initially round tube, which in Area of the turns 6 was compressed from opposite sides, in order to obtain a dragonfly-like cross-sectional shape, as is particularly shown in FIG. 2 can be seen.
  • This cross-sectional shape of the coil 5 brings not only because the upright alignment makes bending the spiral easier, but also leads to a significantly cheaper heat transfer, because initially the Cross-sectional area is reduced compared to the cross-sectional circumference and between the individual turns 6 advantageous flow channels for the warming water result in a cold water pipe 11 in the hot water tank 1 flows, the one covering the drain line 3 Baffle plate 12 opens. As can be seen in FIG.
  • the heat exchanger is located 7 in the cold water area of the hot water tank 1 immediately above the Bottom 4, so that the resulting usable volume above the heat exchanger 7 of the domestic hot water tank 1 is hardly less than the total tank volume.
  • the extension of the heat exchanger 2 in advantageous hot water heating over the entire tank cross-section which results in an optimal stratification of the water.
