Definitions

  • the invention relates to a drinking water line system for a building with at least one cold water line and preferably a hot water line and a fresh water connection to the supply network and a method for cooling the drinking water in a cold water line of a building, the cold water line having a ring line containing at least one consumer, the consumer at least is connected to the cold water pipe and a cooling section.
  • cooling section for cooling the cold water is laid in the ground, the drinking water being circulated in the cold water pipe and a heat exchange being generated between the cooling section arranged in the ground and the drinking water in the cold water pipe.
  • the drinking water line system according to the invention for a building with at least one cold water line and preferably one hot water line and one Fresh water connection to the supply network has a cold water line which is designed as a ring line.
  • the drinking water pipeline system has a cooling section, the cooling section being laid in the ground for cooling the cold water. Since the temperature fluctuations in the ground are moderate over the entire seasons and at a depth of approx. 2 - 13 m there is a temperature between 5 - 18 ° C over the entire year, this can be used to cool the cold drinking water or for a Bring temperature below 25 ° C.
  • the cooling section is preferably formed by a section of the cold water line.
  • part of the cold water line which is designed as a ring line to allow the cold drinking water to circulate in it, runs through the ground, preferably at a depth between 2-13 m, especially preferably between 3-10 m Preferably laid in loops so that enough pipe meters can be inserted into the ground in a narrow space in order to achieve an optimal heat exchange between the lower temperature soil and the higher temperature cold drinking water.
  • At least 1 meter is laid in the ground as a cooling section.
  • the heat exchange between the ground and drinking water takes place in the pipeline via the surface of the pipeline, which lowers the temperature in the drinking water.
  • the cooling section of the pipeline is preferably made of a material that enables good heat exchange.
  • the wall thickness is preferably made as thin-walled as possible so as not to have a highly insulating layer between the soil and the drinking water.
  • the cooling section can preferably also be designed as a separate circuit which is not connected to the drinking water line, the heat exchange between the separate cooling section and the cold water line or the cold drinking water preferably taking place by means of a heat exchanger.
  • the separate circuit is also sunk into the ground, the separate circuit preferably containing a coolant as the cooling liquid. This has the advantage that the temperature difference between the separate circuit, which is used as a cooling section functions is larger and thus more efficient cooling can be exerted on the drinking water.
  • the cold water line has a pump for circulating the cold drinking water. This ensures a regular or constant exchange between the already heated and stagnant drinking water and the drinking water cooled by the cooling section.
  • a preferred embodiment is that the cooling section, which is designed as a separate circuit, has a pump, this enables an exchange between the coolant in the ground and that which flows through the heat exchanger and absorbs the heat of the drinking water or the cold of the coolant the drinking water gives off.
  • the drinking water is circulated in the cold water pipe and a heat exchange is generated between the cooling section arranged in the ground and the drinking water in the cold water pipe.
  • the heat exchange can take place in the drinking water itself, which means that the cooling section forms a section of the ring line of the cold drinking water line and the circulation of the drinking water causes a circulation, whereby the drinking water, which has given off the heat in the cooling section, mixes with the warmer drinking water which lowers the temperature.
  • the cooling section is designed as a separate circuit and the heat of the drinking water can preferably be given off to the cooling section by means of a heat exchanger, whereby the drinking water is cooled.
  • the system 1 has a cold water line 2, which includes a ring line.
  • the drinking water can circulate in the cold water line 2 through the ring line or can be circulated to avoid an increase in the growth of microbes.
  • the drinking water system 1 preferably has a hot water line 3, a pump 9 being arranged in the hot water circuit in order to ensure that the consumers have hot water.
  • a hot water generator 8 is arranged in the hot water circuit, to which fresh drinking water from the supply network 7 is fed.
  • At least one consumer 4 is arranged on the ring line, with the one shown in the figure Figure 1 several consumers 4 are connected, these can also be assigned to different apartments and the drinking water system 1 is connected over the entire building by means of a ring line.
  • the consumers must be connected to one another with at least one ring line so that the drinking water at the consumers or in their feed lines is regularly circulated and the temperature is thereby reduced.
  • the drinking water line system 1 has a cooling section 5, which is laid in the ground and is therefore at a lower temperature. By regularly circulating the water in the cold water pipe 2, the temperature in the drinking water can be kept below 25 ° C.
  • Variants I and II in Fig. 1 show possible ways of laying the cooling section 5 in the ground.
  • Variant I shows that the course of the cold water line 2 is led through the ground and so the subsection 10 of the cold water line 2 forms the cooling section 5, that is, the drinking water circulates directly through the Cooling section, as a result of which the lower temperature in the ground is transferred to the drinking water in the cooling section, which then flows on to the consumers and thereby the drinking water is circulated in the cold water pipe.
  • the circulation through the cooling section prevents the temperature in the drinking water from rising to over 25 ° C.
  • a separate circuit is shown which is arranged in the ground as a cooling section 5. It is advantageous if this cooling circuit has a cooling liquid, preferably glycol, as the circulating medium.
  • the separate cooling circuit 11 then absorbs the low temperatures of the ground or cools down over the ground and can preferably cool the drinking water in the drinking water line in a heat exchanger 12 or absorbs its heat.
  • a pump 13 is preferably arranged there.
