Definitions

  • a temperature of at least 50 °C is a great advantage because legionella bacteria found in drinking water multiply particularly well at temperatures between 25 °C and 45 °C, while at least 50 °C there is no more multiplication and the bacteria from 55 °C are killed.
  • the solution can also be used to keep a cold water distributor cold.
  • the circulation line transports cold water and the heat conduction device conducts heat from the water distributor or connection area to the circulation line. If both a circulating cold and a circulating hot water supply are present, there can be parallel heat conducting devices for cooling the cold water manifold and for heating the hot water manifold. If there is a combined cold/hot water distributor, the hot water part can be heated and the cold water part cooled accordingly.
  • Transfer piece contacted both the circulation line and / or the supply line and the heat conducting device.
  • This transition piece enables efficient heat transfer between the circulation line and the heat conducting device, and it can also be designed in such a way that it can be easily mounted on the circulation line and/or the adjacent section of the supply line.
  • the heat-conducting device is preferably fastened by means of a clamp connection.
  • the transmission piece comprises two half-shell-like elements which together form an elongate, e.g. B. cylindrical end portion of the heat conducting device.
  • the two half-shell-like elements are braced against each other and against the end section, resulting in secure mechanical attachment with good heat transfer.
  • Suitable valves are known per se, they are based, for example, on the Venturi principle or dynamic differential pressure elements.
  • the transfer piece is arranged in the return of the circulation line, no outlet for the supply line is required in the transfer piece. However, it is still possible to structurally combine the transfer piece for the return with a branch from the flow into the supply line. In this way, the individual fluid-conducting and thermal connections to and from the circulation line can be created with a single component for part of a building.
  • Discharge lines 7.1, 7.2, 7.3, 7.4 lead from the water distributor 10 to four consumers 8.1, 8.2, 8.3, 8.4, the example shown being a washstand (consumer 8.1), a shower (consumer 8.2), a sink (consumer 8.3) and a bathtub (consumer 8.4).
  • the other supply lines are in the figure 1 shown only in outline, but designed analogously to the supply line 4.
  • the figure 3 shows in a schematic way the connection of the heat pipe of the water distribution.
  • the shut-off element and the water meter are not shown in the supply line 4, which leads from the circulation line 1 to the water distributor 11.
  • a direct connection is shown, whereas a transfer piece is used within the scope of the exemplary embodiment.
  • the curve 61 qualitatively represents the temperature profile from the center point of the circulation line 1 to the interior 43 of the heat pipe 40.
  • the other leg of the transfer piece 130 has a first area in which two line sections 138, 139 run parallel next to one another, a second section in which the two line sections 138, 139 are connected to one another, and a supply connection 137 for connection to the water distribution system of the Supply line leading to parts of the building.
  • a flow divider valve 70 is arranged in the first leg between the supply line termination 135 and the discharge line termination 136 .
  • the flow divider valve 70 opens so that a large part of the flow passes through it, i.e. the water flows in a straight line from the supply connection 135 to the discharge connection 136 .
  • the water flows from the supply line connection 135 first along the line section 138 with a sector ring-like cross-section, then after a deflection by 180° in the second area of the corresponding leg along the line section 139 with a circular cross-section to the discharge connection 136.
  • the water flows from the first line section 138 directly through the supply connection 137 into the supply line.
  • the start of the heat pipe 40 is accommodated in a receptacle 132, a conductive paste also being applied here between the heat pipe 40 and the transmission piece 130 before assembly.
  • the heat pipe 40 extends in a straight line from the transfer piece 130, being arranged to have an inclination of about 3° to the horizontal, rising from the transfer piece 130. As shown in FIG.
  • the supply connection 137 is offset laterally to the heat pipe 40 .
  • the figure 9 shows a comparison of the temperature profile in a supply line with and without temperature control of the water distributor using a heat pipe. It represents comparative measurements based on a realistic functional model.
  • the temperature was measured at the following points, among others: location Distance from the circulation line [mm] circulation line 0 Beginning of supply line 102 in front of shut-off valve 516 in front of water distributor 930 Center water distributor 1213
  • the invention is not limited to the exemplary embodiments shown.
  • the dimensioning of the heat-conducting device can be selected differently, and the connection to the circulation line and/or the water distributor can take place in a different way.
  • the line sections in the transfer piece can be provided with inward profiling, e.g. B. rib-like profiles.
