Definitions

  • the invention relates to an enclosed by an insulation hot water tank in conjunction with at least one mounted on it hydraulic module for thermal storage loading and unloading.
  • Hot water storage tanks are used to store thermal energy. In most cases, heating or service water is stored in them. In order to supply the storage thermal energy, is often located in the hot water tank, a helical heat exchanger, which is traversed by a heating medium. Another possibility is that the hot water tank from the lower area is withdrawn cool water, which is heated in an external heat exchanger and then returned to the memory. If the hot water storage tank contains heating water, the heat from the heating water for DHW heating must be transferred to the service water in a heat exchanger. For this purpose, on the one hand can be arranged within the hot water tank, a helical heat exchanger, which is flowed through by the hot water. Another possibility is to remove warm heating water from the hot water tank and transfer part of its thermal energy in an external plate heat exchanger to the hot water.
  • hydraulic modules are used for loading and / or unloading a hot water storage tank.
  • These hydraulic modules represent a structural unit and contain, in addition to a housing, at least one circulating pump and a secondary heat exchanger, which is usually designed as a plate heat exchanger.
  • the secondary heat exchanger is connected to the hot water tank with two connections, so that water can be withdrawn or supplied and thus heat can be introduced into the hot water tank or withdrawn.
  • hydraulic modules are fastened to the outside of a hot water tank by means of screws, then the hydraulic lines of the hydraulic modules are connected to the connections of the hot water tank.
  • EP 784192 A1 the connection of a hot water tank with a heating device is known in which the hot water tank rails for connecting to the housing of the heater and hydraulic connections are mounted so that the heater must be inserted only in the rail for connection and bolted to the terminals.
  • GB 2241564 A shows a heater with prefabricated connections for connection to an outside of the heater housing mounted circulation pump and a switching valve.
  • the invention has for its object to simplify the suspension and attachment of hydraulic modules to hot water tanks and to reduce the heat losses.
  • the figures show a hot water tank 1 with four hydraulic connections 5, 6, 7, 8 at different height level, wherein the hydraulic connections 5, 6, 7, 8 penetrate a wall 4 of the hot water tank 1 on one side.
  • the hot water tank 1 is enclosed by an insulation 15, wherein the insulation 15 at the location of the hydraulic connections 5, 6, 7, 8 has recesses.
  • the hydraulic connections 5, 6, 7, 8 have on the outside of the hot water tank threaded. In this thread of the hydraulic connections 5, 6, 7, 8 engage four connecting pipes 9, 10, 11, 12 and thus penetrate the insulation 15th
  • the rear walls 16, 17 of the hydraulic modules 2, 3 have openings, which surround the connection pipes 9, 10, 11, 12.
  • On the side facing away from the hot water tank 1 side of the connecting pipes 9, 10, 11, 12 are external thread, which serve to secure the rear walls 16, 17 of the hydraulic modules 2, 3 to the hot water tank 1 by means of appropriate nuts.
  • the connecting pipes 9, 10, 11, 12 have on the memory-facing side within the thread via radially circumferential grooves 13, in each of which a radial seal 14 is arranged.
  • the connecting pipes 9, 10, 11, 12 are first in the grooves 13 of the connecting pipes 9, 10, 11, 12 radial seals 14 inserted. Then the connecting pipes 9, 10, 11, 12 are inserted through the openings in the insulation 15 and screwed to the hydraulic connections 5, 6, 7, 8.
  • the radial seals 14 seal off the transitions waterproof. Are the connecting pipes 9, 10, 11, 12 screwed, so they protrude beyond the insulation 15 of the hot water tank 1 addition.
  • the connecting pipes 9, 10, 11, 12 have on the side facing away from the hot water tank 1 side over a larger diameter than on the hot water tank 1 associated side.
  • the hydraulic modules 2, 3 are now placed such that the passages in the rear walls 16, 17 of the hydraulic modules 2, 3 are slipped over the connecting pipes 9, 10, 11, 12.
  • connection pipes 9, 10, 11, 12 are connected to the pumps 18, 19 and the plate heat exchangers 20, 21 of the hydraulic modules 2, 3.
  • the secondary side of the plate heat exchanger 20 of the hydraulic module 2 is connected to a solar collector, so that the hydraulic module 2 serves as a solar station.
  • the secondary side of the plate heat exchanger 21 of the hydraulic module 3 is connected to service water pipes, so that the hydraulic module 3 serves as a fresh water station.
  • the hydraulic piping can also be used as a fastener. This not only provides a simple way of mounting. Rather, a better insulation of the hot water tank 1 is achieved because except the piping penetrate no further thermal bridges for fixing the hydraulic modules 2, 3 between the hot water tank 1 and the environment, the insulation 15.
