Definitions

  • the invention is based on a method for regulated heat transfer from a primary steam network to a heat consumer, the flow of which is supplied at a predetermined excess pressure and the return of which is at a relatively low pressure, the heat taken from the steam network as a function of the heat consumption by the consumer Steam is cooled by heat extraction by means of a secondary medium while maintaining a predetermined overpressure in relation to the supply pressure of the heat consumer until it is condensed, and the excess pressure in a jet pump is then reduced to the supply pressure of the heat consumer while generating a corresponding driving energy for the supply and thereby the supply the secondary medium heated to the cooling of the steam is mixed.
  • the invention is based on a device for controlled heat transfer from a primary steam network to a heat consumer, with a heat exchanger controlled by condensate accumulation as a function of the temperature to the heat consumer, which on the steam side with the steam network and on the condensate side with the driving nozzle of one in the flow line of the heat consumer lying jet pump is connected, the driving nozzle of which is pressurized with the predetermined overpressure, the jet pump on the suction side in a secondary circuit of the heat exchanger, in which flows the steam-heated secondary medium, which flows through the jet pump in a predetermined proportion to the flow of the heat consumer is admixable.
  • the heat exchanger is connected to the steam line of the primary steam network via a multi-function valve.
  • the conduits used in the heat exchanger for condensation are connected to the jet nozzle of a jet pump, a line serving as a feed line leading from the jet pump to the heat consumer, the return of which opens via a pressure-maintaining valve to the condensate return line of the primary steam network.
  • a line branches off, with which the secondary medium is branched off from the condensate to be returned, which secondary medium is fed into the associated flow connection of the heat exchanger.
  • the secondary medium in the heat exchanger After the secondary medium in the heat exchanger has been heated by condensation of the steam, it arrives via a further connecting line to the suction side of the jet pump, from where it is then mixed with the condensate flowing out of the heat exchanger for heat transfer to the heat consumer.
  • the temperature of the flow of the heat consumer is regulated via the multi-function valve provided on the steam side, via which the condensate build-up in the heat exchanger is also regulated at the same time.
  • a pressure loss occurs at the multi-function valve, so that under certain operating situations it is necessary to provide a pressure booster pump which is electrically operated in the flow line for the heat consumer, specifically behind the jet pump.
  • the object of the invention is therefore to further develop the above-mentioned method in such a way that no pressure booster pump is required behind the jet pump while at the same time saving fittings.
  • the method is characterized according to the invention by the features of the main claim, while the device for solving the problem is characterized according to the invention by the features of claim 3.
  • the cold secondary medium can expediently be branched off from the cooled return line of the heat consumer.
  • a pressure-maintaining valve can be arranged in terms of flow behind the branching off of the secondary circuit.
  • the pressure-maintaining valve can have a further connection which is connected to the connecting line between the condensate side of the heat exchanger and the jet pump, in the steam line for the heat exchanger is a level controller controlling the pressure control valve, through which the pressure control valve can be reversed in order to remove excess condensate such that the condensate can be discharged directly into the condensate return line of the steam network, bypassing the heat consumer and the jet pump.
  • a hot water heater can be contained in the heat exchanger.
  • the illustrated steam water heating system 1 serves to transfer heat from a primary steam network 010 to a heat consumer designated by 2.
  • the heat consumer 2 can, depending on the design of the system as a heating, ventilation, air conditioning, production or hot water preparation system for radiators or registers or heating devices and the like. Like. Be trained.
  • the system has a heat exchanger 4 connected to the steam network 010 via a line 3, in which a tube coil bundle 5 is arranged, which is connected on the steam side to line 3 and on the condensate side to a connecting line 6.
  • the connecting line 6 leads from the tube coil bundle 5 to the drive nozzle connection 8 of a jet pump 9 with a variable drive nozzle 10, the collecting nozzle or the diffuser 11 of the jet pump 9 being connected to a feed line 12 of the heat consumer 2.
  • a return line 13 leads from the heat consumer 2 via a multi-function valve 14 to the condensate manifold 012 of the steam network.
  • the heat exchanger 4 also has two connections 15 and 16 for the secondary medium, which is passed through the heat exchanger 4 in a countercurrent process and is branched in terms of flow upstream of the multi-function valve 14 from the return line 13 via a line 17 and is fed into the connection 15. After flowing through the heat exchanger 4, the secondary medium flows out of the connecting piece 16 of the heat exchanger 4 and from there reaches the suction side 18 of the jet pump 9.
  • a level sensor 19 is provided above the heat exchanger 4 in the connecting line 3, said level sensor 19 having a magnet 20 of the magnetically controlled multi-function valve 14 controls, which is connected via a further connection 21 to the condensate-carrying line 6.
  • the multi-function valve 14 is designed as a pressure-maintaining valve and is controlled via a pressure transmitter 22 provided in the return line 13 so that a predetermined pressure is maintained in the line 13.
  • a temperature sensor 23 is located in the flow line 12 and is connected to a control device 25 acting on an actuator 24.
  • the actuator 24 serves to regulate the driving nozzle 10, which in the exemplary embodiment is provided with a nozzle needle 26 for changing the nozzle cross section.
  • the arrangement of the actuator 24 and jet pump 9 is such that the condensate flow into the connecting line 6 or in the flow line 12 and the heat consumer 2 is continuously adjustable between the zero flow rate and the maximum flow rate using the adjustable drive nozzle 10.
  • steam flows from the steam network 010 via the line 3 into the coils 5 of the heat exchanger 4, where it condenses while heating the secondary medium washing around the coils 5.
  • the condensate formed is essentially under the pressure of the steam network 010 and flows via line 6 to the adjustable driving nozzle 10 of the jet pump 9.
  • the adjustable driving nozzle 10 of the jet pump 9 Depending on the position of the nozzle needle 26 of the adjustable driving nozzle 10, more or less condensate flows through the jet pump or into the diffuser 11 and thus into the flow line 12 of the heat consumer 2.
  • the connecting piece 16 on the suction side 18 secondary medium heated by the condensing steam is canceled from the heat exchanger 4 and mixed with the condensate flowing into the diffuser 11 in accordance with the position of the adjustable driving nozzle 10, so that the heat consumer 2 is finally supplied with a mixture of condensate and secondary medium.
  • the flow temperature measured in the flow line 12 by the sensor 23 is above or below a predetermined setpoint, so that the control device 25 adjusts the actuator 24 and thus the nozzle needle 26 in the direction of maintaining the setpoint temperature.
  • the adjustable driving nozzle 10 is closed, with the result that more condensate is accumulated in the heat exchanger 4 and less steam is removed from the steam network 010. At the same time, the driving energy behind the driving nozzle 10 is reduced and less secondary medium is pumped out of the heat exchanger 4 and supplied to the heat consumer 2. If the temperature measured in the flow line 12 is below the target temperature, i. H. the heat consumer 2 removes more heat, so in the opposite sense the driving nozzle 10, controlled by the control device 25 and the actuator 24, is turned on and the condensate throughput and the throughput of secondary medium are increased.
  • the level sensor 19 responds, which then releases the connection 21 of the multi-function valve 14 via the magnet 20, so that condensate from the line 6 is discharged directly bypassing the jet pump 9 and the heat consumer 2 into the return line 012 of the steam network with the help of the steam pressure on the condensate.
  • the multi-function valve together with the pressure transmitter 22 serves at the same time to maintain a certain minimum pressure in the return line 13 hold and to prevent possible idling.
