Definitions

  • the invention relates to a domestic water heater for mobile applications, with a water heater. Furthermore, the invention relates to a method for heating process water in mobile applications.
  • Gas is relatively widespread as an energy source for heating process water.
  • the not always guaranteed availability of the gas as well as the danger of fire and explosion due to improper use and / or in the absence of regular maintenance have proven to be disadvantageous.
  • the gas storage bottles require not inconsiderable storage space and reduce the potential load capacity of the motorhome.
  • a domestic hot water heater for mobile applications which uses heated by a heating device heated air to heat the service water.
  • the already available for the vehicle heated air is also used to heat the service water.
  • a disadvantage is, inter alia, that when using the heated air exclusively for heating the service water with air, a medium having a relatively low specific heat capacity is used. This can have an adverse effect on the efficiency or on the size of the hot water heater.
  • the invention has the object of developing the generic hot water heaters so that they ensure a reliable independent of the energy sources gas or electricity heating of the service water in a simple and efficient manner.
  • the hot water heater according to the invention builds on the generic state of the art in that the hot water heater has a fluid / hot water heat exchanger, wherein the fluid heat energy by a Zu- rate heater can be supplied and the heat energy of the fluid through the heat exchanger is at least partially transferable to the hot water. It can be used in an advantageous manner to already existing components such as an auxiliary heater or an already used fluid. By using a fluid as a heat carrier for heating the process water, in particular a heat transfer medium with a high specific heat capacity can be used. Furthermore, the hot water heater according to the invention has the advantage that by means of the additional heater, the fluid can be brought within a selected frame to an arbitrary temperature and thus also for the service water a possibly desired high heating can be realized.
  • the fluid can absorb any waste heat that may be present in the engine of the motorhome and use it to heat the service water.
  • the hot water and the fluid can be separated from each other to take into account food concerns.
  • the fluid / hot water heat exchanger may be configured as a countercurrent heat exchanger to produce an efficient heat transfer.
  • other designs such as a heat exchanger according to the continuous flow heater principle are conceivable in which the process water is conducted in thermal contact with the fluid within it or a heat exchanger in which the fluid, conducted inside the process water, gives off this heat energy.
  • the fluid forms a heat transfer medium of a closed heat transfer medium circuit.
  • the heat transfer circuit may be, for example, a coolant circuit of a motorhome.
  • the domestic water heater can be integrated in an existing circuit.
  • the closed heat transfer medium circuit can be heated independently of the domestic water energy requirement by means of the auxiliary heater and additionally or exclusively used for heating the service water by means of the fluid / hot water heat exchanger.
  • the closed nature of the circuit allows a material separation of fluid and service water with simultaneous thermal contact.
  • the heat carrier circuit comprises solenoid valves.
  • the solenoid valves can be used to control the heat transfer from fluid to service water. For example, in the case of a high service water demand, the fluid flow through the fluid / service water heat exchanger may be increased, while possibly other energy consumers of the heat transfer circuit may also be allocated a smaller fluid flow or may possibly be completely decoupled. Alternatively, the. Fluids / hot water heat exchangers are completely removed from the heat transfer fluid circuit by appropriately switched valves, if no further hot water heating is desired.
  • a likewise preferred embodiment of the invention results from the fact that the additional heater is operable with a liquid fuel.
  • the additional heater is operable with a liquid fuel.
  • the fuel can be taken directly from the fuel tank of the motorhome be removed and so a simple supply of the auxiliary heater and thus the domestic water heater in stand mode as well as while driving the motorhome be achieved.
  • the heat exchanger is disposed within the hot water tank. This arrangement facilitates the contacting of a relatively large surface of the heat exchanger with the process water. For example, the service water, directly flow around areas or surfaces of the heat exchanger. If necessary, parts of the heat exchanger can protrude directly into the service water and thus enable a good heat transfer.
  • the heat exchanger forms a pipe section of the heat transfer medium circuit.
  • the pipe section can, for example, dive directly into the hot water tank and heat the hot water by means of the heat transfer fluid flowing through it.
  • the pipe section is helical.
  • the helical configuration enlarges the surface of the heat exchanger which is available for emitting the heat energy and thus improves the thermal contact between heat transfer fluid and service water.
  • the hot water tank has an insulation. This ensures a supply of hot domestic water for a longer time after switching off the hot water heater.
  • the hot water tank has a cylindrical tank. Such a shape allows a cost-effective production due to a small number of welds.
  • the invention further relates to a method for heating service water of mobile applications, comprising the following steps:
  • the invention is based on the knowledge to use an already existing in a motorhome auxiliary heater, such as a heater, for heating domestic hot water.
  • a coolant / hot water heat exchanger is incorporated into the coolant circuit connected to the auxiliary heater. This can for example be designed as a spiral or helical pipe section and in the service water tank hin- - -
  • a control of the energy delivered to the hot water can be done for example via solenoid valves, which supplies the heating power of the auxiliary heating of the domestic water heating, the heating of the interior or both.
  • FIG. 1 shows a hot water heater according to the invention
  • Figure 2 is a block diagram of a closed heat transfer circuit with a hot water heater according to the invention.
  • FIG. 3 shows a flowchart for explaining an embodiment of the method according to the invention
  • the hot water heater 10 has a hot water tank 12. This has a circular cylindrical basic shape and is arranged horizontally in the present embodiment. On its underside, the hot water tank 12 has a service water inlet pipe 60, on its upper side a service water outlet pipe 62. These are arranged in the vicinity of the opposite end faces of the circular cylinder and are thus diametrically opposite. Within the service water tank 12 is the service water 20 to be heated. This is opposite to the environment of the service water tank 12 by a ge suitable thermally insulating wall 32 protected against heat energy loss.

  • the heat exchanger inlet 68 and the heat exchanger outlet 70 are connected to the flange connection piece 64.
  • a coolant 16 At the hot water tank 12 side facing the Flanschan gleich Swisss 64, a pipe section 28 of the heat exchanger 14 connects. This extends substantially U-shaped within the hot water tank 12, wherein the heat exchanger outlet 70 associated leg is formed as a helix 30.
  • the heated coolant 16 flows via the pipe section 28 into the interior of the service water tank 12.
  • the coolant 16 flows through, inter alia, the coil 30.
  • the coil 30 is completely surrounded by service water 20 and is thus over the wall of the tube of the helix 30 in close thermal contact with the coolant 16. This can thus a part of its heat energy to the hot water 20th submit.
  • FIG. 2 shows a block diagram of a closed heat transfer circuit with a hot water heater according to the invention.
  • the illustrated block diagram shows the integration of the heat exchanger 14 in a closed coolant circuit.
  • This is formed by an auxiliary heater 18 and a vehicle engine 46 of the motorhome and corresponding lines.

  • a fuel 26 is burned, which is also used by the engine 46 for driving the motor vehicle.
  • the fuel 26 may be, for example, diesel oil. to act the gas.
  • the fuel 26 is located in a fuel tank 48 and is supplied via the lines 80, 82 to the auxiliary heater 18 and the internal combustion engine 46.
