Definitions

  • the invention relates to a device for heating service water in the course of a heat exchanger connected on the one hand to a service water line and on the other hand to a guided over a heat storage heat transfer circuit and with a depending on the flow rate of the service water circulating pump for the heat transfer circuit.
  • the heat exchanger provided for this purpose at a demand for hot water via the flow of the heat storage hot heat transfer medium, usually water, be supplied, in one of the heat demand for Domestic water heating dependent amount.
  • This dependence is ensured in known devices of this type in that the usually electrically driven circulation pump for the heat transfer circuit is turned on by a provided in the course of the service water flow switch, so that with the removal of hot water through the heat exchanger this a suitably heated heat transfer from the heat storage is supplied ,
  • the heat carrier quantity required in each case for a given service water temperature is determined on the basis of the service water temperature and the heat carrier temperature and adjusted by means of a controller which regulates either the delivery rate of the circulation pump or a quantity valve. In both cases, however, the control and regulatory effort is great, what is more, a significant energy needs for the operation of the circulation pump.
  • the invention is therefore based on the object, a device for heating of process water of the type described in such a way, that a simple, reliable and less susceptible to interference control for the heat transfer circuit is made possible without having to do without an economic adjustment of the heat exchanger with the aid of the heat transfer amount of heat to the required heat for domestic water heating.
  • the invention achieves the stated object by providing a service water, which can be acted upon by service water and is connected to the circulation pump by a drive-connected turbine, in the service water line.
  • the invention makes the fact to own, that in domestic water pipes usually a pressure of 2 to 6 bar prevails, so that this pressure when removing domestic water to drive a turbine can be used, which in turn drives the circulation pump for the heat transfer circuit with the advantage that the flow rate of the heat carrier depends directly on the flow rate of the hot water to be heated, because the speed of the turbine is determined by the flow rate of the service water and the speeds of the turbine and the circulation pump for the heat carrier in a predetermined ratio to each other.
  • the heat transfer medium supplied to the heat exchanger for heating the process water is always adapted to the quantity of service water removed via the heat exchanger, which is independent of the removal quantity, provided that the flow of the heat storage for the heat carrier has a predetermined temperature , Constant hot water temperature leads, and without additional energy to promote the warm heat transfer medium through the heat exchanger.
  • the subject invention is for example shown, namely a device according to the invention for the heating of process water in the flow is shown in a simplified block diagram.
  • the illustrated apparatus for heating service water has a heat exchanger 1 operated in the sense of a continuous flow heater, which is connected, on the one hand, to a service water line 2 and, on the other hand, to a heat transfer circuit 3.
  • the heat transfer circuit 3 comprises a heat storage 4 for a heat transfer medium, usually water, wherein the flow 5 of the heat accumulator 4 is connected to the heat exchanger 1.
  • a circulation pump 7 is arranged, with the help of the heat exchanger 1 hot heat carrier is supplied, when hot service water of the service water pipe 2 is removed via a removal valve 8.
  • the circulation pump 7 is not driven by a complicated control via an electric motor, but by means of a turbine 9, which is turned on in the service water pipe 2.
  • the prevailing in the service water pipe 2 pressure is used in a withdrawal of service water for the drive of the turbine 9, which is drivingly connected to the circulation pump 7.
  • the wheels of the turbine 9 and the circulation pump 7 can sit on a common shaft 10, as indicated in the drawing.
  • the turbine 9 and the circulation pump 7 can be combined in a common housing 11 to form a structural unit, which is then only connected to the service water pipe 2 and to the heat transfer circuit 3.
  • the service water flow requires a drive of the turbine 9 and thus of the circulation pump 7 so that inevitably hot heat transfer medium is supplied to the heat exchanger 1 via the supply line 5, in a quantity dependent on the dispensing quantity of the service water. Because of this determined by the turbine drive flow rate of the heat carrier can be ensured in a simple manner, a predetermined, independent of the respective tap quantity removal temperature for the process water. Not only the advantage of a simple control of the heat carrier circuit 3 is used, but also achieved an independence of the control of the heat carrier circuit 3 of an external energy, so that, for example, the heating of the service water through the heat exchanger 1 is not affected by a power failure.
