Definitions
- the invention relates to a device for heating Sanitary water with a container for sanitary water in order around which there is a space delimited by walls, in which a tortuous plumbing pipe with some Coils are added that are connected to the container is.
- Such a device also referred to below as a "dispenser” is known from DE-A-19526862.
- the dispenser according to the prior art comprises a relatively large container for sanitary water with a Side wall, around which an annular heating water room is appropriate.
- the helical line extends between the side walls of the heating water room, causing heating water (in countercurrent) helically through the heating water room flows parallel to the sanitary water pipe.
- a disadvantage of the known dispenser is the fact that the heat transfer between the heating water and the sanitary water is not optimal because the heating water only in contact with part of the sanitary water pipe stands.
- Another disadvantage of the known dispenser is in that it is very cold from an initial state takes a long time (namely until the sanitary water in the container was replaced) until heated sanitary water was supplied can be.
- the invention intends to create a dispenser, both a cold and a warm one Initial state quickly the desired amount of sanitary water can deliver at the desired stable temperature.
- Another goal is to create a dispenser, at which the temperature of the heated sanitary water supplied is relatively insensitive to fluctuations in the flow rate of the sanitary water.
- Another object of the invention is to reduce or Prevent limescale from settling on the water parts of the dispenser in contact.
- Yet another object of the invention is to create it a dispenser that is compact and cheap, and that with only a small pressure drop for the heating water and the sanitary water works.
- the device of the type mentioned according to the invention characterized in that the Sanitary water pipe at a certain distance from the Walls of the heating water room.
- the heating water can so the plumbing water pipe, whose turns preferably, but not necessarily, in a certain distance from each other, rinse completely, so that an optimal heat transfer of the heating water to the sanitary water can take place. That can go on Heating water in this way both in parallel and flow across the turns of the sanitary water pipe, what benefits heat transfer and for a low one Pressure drop in the heating water in the dispenser provides.
- the supply temperature of the heating water for example from a A burner's heat exchanger comes down. This avoids local hot zones in the sanitary water, what reduces limescale deposits in the dispenser or avoids.
- the temperature of the sanitary water in the dispenser is smaller. It also improves the tap efficiency.
- a lower heating water discharge temperature increases the energy from the heating water at its Warming can be absorbed.
- Sanitary water discharge temperature thanks to the low supply temperature the heating water less sensitive to fluctuations in the flow rate of the sanitary water.
- a temperature sensor in the drained sanitary water which is usually for temperature control of the discharged sanitary water is dispensed with and submit for the purpose of such a regulation Temperature sensor off, which is usually already in the Heating water supply is available.
- spacers The distance between the sanitary water pipe and the Walls of the boiler room, including the wall of the Container, is ensured by spacers.
- the Spacers formed by locally removing the walls of the Boiler room deformed, separate spacers can but also remedy, preferably in the form of elongated elements as if attached to the walls Ribs that run across the turns of the Sanitary water pipe extend.
- the Sanitary water pipe at least two helical winding line parts, which are coaxial to each other are arranged. This distribution of Sanitary water pipe in pipe parts provides one significant enlargement of the heat-exchanging surface.
- the individual line parts are preferably in interconnected annular spaces arranged, with an annular wall between the line parts is appropriate.
- the heating water in the ring-shaped Can be crossed in countercurrent to the sanitary water flow the line parts, so that a very good Heat transfer and a very large heating capacity is achieved. This allows the length of the Sanitary water pipes are limited, which only one low pressure loss of the sanitary water over the Conveyor vessel has the consequence, and that too Heating water must travel a limited way, so that the pressure drop in the heating water over the Dispenser is small.
- Integrating a container with sanitary water into the Dispenser leads to a warm initial condition fast delivery of hot sanitary water because it is in the Container is kept in stock, especially if a Sanitary water inlet opens and enters the tank Sanitary water outlet with the end facing away from the container the sanitary water pipe is coupled.
- the limescale in the dispenser is also in accordance with the Invention by its relatively low Operating temperature reduced, first because immediately after Sanitary water was tapped and the tapping was stopped, cold water in the tank the average temperature decreased. Second is thanks to the in the heating water room located container a relatively small amount Heating water available in the dispenser, which is additional can contribute to the fact that the average temperature in Dispenser is lowered. Third, the temperature of the Heating water in the dispenser during dispensing thanks to the improved heat transfer in the dispenser is lower his.
- the ratio is Amount of sanitary water in the dispenser to the amount of heating water got bigger.
- the integration of one leads Container with sanitary water in the dispenser at one cold initial condition to a quick delivery warm Sanitary water, since there is relatively little heating water in the Dispenser is located, which flows quickly.
- the Sanitary water pipe the container which is a very compact, simple and therefore cheap construction results.
- the container is centrally located in the heating water room, so that following the tap of sanitary water if that Cones finished, direct and very effective
- the sanitary water in the tank is heated.
- the heating water and the sanitary water in heat is removed from the sanitary water pipe cool evenly, causing limescale in the dispenser reduced. Even if several times in quick succession Sanitary water is tapped, it becomes an undesirably high Temperature prevented.
- the Container is annular, and is the Sanitary water pipe surrounded by the tank. Also in this Fall finds direct heating of the sanitary water instead, but inside out (assuming that the sanitary water first through the tank and then flows through the sanitary water pipe and the heating water in cross-counterflow to the sanitary water flows). The warmest heating water is in the central part of the device so that the Cooling losses are relatively low.
- the container can on the top and bottom of the device extend further by means of a double wall.
- Figures 1 and 2 show a dispenser, the one cylindrical jacket 1, for example made of steel an upper wall 1a and a lower wall 1b.
- the shell 1 Within the shell 1 are three concentric annular partitions 2a, 2b and 2c for example made of steel.
- the partitions 2a and 2c are attached to the bottom wall 1b of the jacket 1, a annular gap between the top of each Wall 2a, 2c and the top wall 1a of the jacket 1 open remains.
- the partition 2b is on the Top wall 1a attached, the annular gap between the lower edge of the partition 2b and the Bottom wall 1b of the jacket 1 remains open.
- the Partitions can also be placed in the column continue and there with one or more Perforations are provided.
- the spiral 4 comprises three helical parts: a first Part lies between the partitions 2a and 2b the second part lies between the partitions 2b and 2c and a third part lies between the intermediate wall 2c and the side wall of the jacket 1.
- the centrally located Container 3 and the parts of the spiral 4 are such connected that sanitary water to be heated, that flows into the jacket 1 on one Sanitary water inlet 7 first in the container at the Bottom flows in and from the top of the container 3 out into the top turn of the first part of the Spiral 4 flows. Then the sanitary water flows from the lowest turn of the first part of the spiral 4 to the lowest turn of the second part of the spiral 4 and from the top turn of the second part of the Spiral 4 to the top turn of the third part of the Spiral 4.
- the sanitary water leaves the jacket 1 through one Sanitary water outlet 8.
- the sanitary water and the heating water can also in opposite directions to those previously described flow in the respective directions through the dispenser.
- the jacket 1 and the Partitions 2a, 2b and 2c each with ribs 9 for Example made of plastic or metal.
- Ribs 9 ensure that the turns of the spiral in one certain distance from the jacket 1, the partitions 2a-2c and the container remain for optimal flow of the dispenser through the heating water and a optimal heat transfer between the heating water and to ensure the sanitary water.
- the container 3 can be provided with ribs 9 to the partition 2a to keep at a certain distance.
- the ribs or other spacers can also be formed by the respective wall in a deep-drawing process appropriately deformed.
- FIG. 3 shows a dispensing vessel, which comprises: a jacket 1 with an upper wall 1a and a lower wall 1b, one Partition wall 2d, which on the lower wall 1b of the jacket 1 is attached, with an annular gap between the Partition wall 2d and the top wall 1a is released; a centrally arranged cylindrical container 3, a spiral 4 with two helically wound Line parts that are arranged concentrically and have adjacent turns, one Heating water inlet 5, a heating water outlet 6, a sanitary water inlet 7, which extends to the upper part of the container 3 extends into a sanitary water outlet 8 and ribs 9.
- the sanitary water flows in the dispenser from Sanitary water inlet 7 to the sanitary water outlet 8 while the heating water from the heating water inlet 5 to Heating water outlet 6 flows.
- FIG. 4 shows a dispensing vessel, which comprises: a jacket 1 with an upper wall 1a and a lower wall 1b, one Partition 2e, which on the top wall 1a of the jacket 1 is attached, with an annular gap between the Partition 2e and bottom wall 1b is left free, an annular container 3 located on the side wall of the jacket 1 extends a centrally arranged spiral 4, a heating water inlet 5, a Heating water outlet 6, a sanitary water inlet 7, a sanitary water outlet 8 and a spacer 10.
