Definitions

  • the invention relates to a heating system with a hydraulic switch in the preamble of Claim 1 mentioned type.
  • Heating systems include a producer circuit and a consumer circuit.
  • the producer group contains At least one heat generator, the consumer group at least one heat consumer.
  • the Independent sizes of the heating system are the temperatures in the flow and the return of the Consumer circuit, as well as the volume flow in the consumer circuit, while the temperatures in Flow and return of the producer circuit, as well as the volume flow in the producer circuit as that dependent sizes are to be considered.
  • Volume flow at the volume flow required by the heat consumers are the producer circuit and the consumer circuit is decoupled by a hydraulic switch. In practice, this has the following Effects: If the volume flow in the generator circuit is greater than the volume flow in Is consumer circuit, then a preliminary admixture takes place in the Generator circuit, causing the return temperature in the generator circuit to rise.
  • the return temperature be as low as possible. If the volume flow in the generator circuit is smaller than the volume flow in the consumer circuit, then a return mixture is added in the consumer circuit, whereby the flow temperature in the consumer circuit drops. For Coverage of the heat demand from the consumer must then either the volume flow in Consumer group are increased, whereby the return admixture in the consumer group still amplified, or the flow temperature of the generator circuit must be increased.
  • the invention has for its object in a heating system with a hydraulic switch the volume flow flowing in the generator circuit depending on the flow in the consumer circuit To control volume flow so that the return temperature in the generator circuit is as low as possible.
  • the generator circuit 1 shows a heating system with a generator circuit 1, a consumer circuit 2 and a hydraulic switch 3 for the hydraulic decoupling of the generator circuit 1 and the consumer circuit 2.
  • the generator circuit 1 comprises a flow line 4 and a return line 5, between which at least one heat generator 6 is arranged is.
  • a means 7 is used to control the volume flow V E flowing through the generator circuit 1.
  • the means 7 is a controllable pump or a throttle valve which is built into the return line 5 of the generator circuit 1.
  • the consumer circuit 2 also comprises a flow line 8 and a return line 9, between which a single or several heat consumers 10 are arranged.
  • the volume flow V E flowing through the load circuit 2 flows to the volume flow V V. If the volume flows V E and V V are different, then a volume flow V W also flows through the hydraulic switch 3.
  • the positive flow direction of the volume flows is marked with arrows in FIG. 1.
  • the size of the volume flow V V required by the heat consumers 10 is determined, depending on the design of the heating system, by mixing valves, thermostatic valves, pumps, taps, etc. arranged on the consumption side. According to the invention, the return temperature in the generator circuit 1 becomes minimal when the volume flow V W flowing through the hydraulic switch 3 almost disappears.
  • TV E denotes the temperature in the flow line 4 of the generator circuit 1
  • TV V denotes the temperature in the flow line 8 of the consumer circuit 2
  • TR V denotes the temperature in the return line 5 of the consumer circuit 2
  • TR E denotes the temperature in the return line 9 of the generator circuit 1.
  • the temperatures TV E , TR E , TV V and TV E are not independent of one another, but depend on the volume flow V W caused by the hydraulic Soft 3 flows. This dependency is used according to the invention in order to minimize the volume flow V W.
  • all four temperature measuring points TV E , TR E , TV V and TV E are equipped with a temperature sensor.
  • the temperatures TV E , TR E , TV V and TV E are recorded by a control and regulating device 11.
  • the control and regulating device 11 controls and / or regulates the means 7 for controlling the volume flow V E flowing in the generator circuit 1 in such a way that the volume flow V E is reduced, provided that TR E > TR V and that the volume flow V E is increased, if TV E > TV V.
  • At least the two temperature measuring points TV E and TV V are equipped with a temperature sensor.
  • the control and regulating device 11 controls and / or regulates the volume flow V E with the means 7 in such a way that the difference TV E - TV V is as small as possible, but larger than a positive value dT 1 .
  • At least the two temperature measuring points TR E and TR V are equipped with a temperature sensor.
  • the control and regulating device 11 controls and / or regulates the volume flow V E with the means 7 in such a way that the difference TR E - TR V is as small as possible, but larger than a value dT 2 .
  • the regulation on the value TR E - TR V 0 not sensible, since the volume flow V W through the switch 3 could then become arbitrarily large negative.
  • the advantage of the invention is that the temperature TR E on the generator side of the return line 5 is as low as possible.
  • the walls of the combustion chamber are as cool as possible and therefore the condensation of the exhaust gases produced during combustion is maximal and the heat loss due to escaping warm exhaust gases is minimized.
  • an advantage of the invention is that the flow temperature of the generating circuit 1 can be kept as low as possible, since no or only a little cool water is added to the flow. The efficiency of the heat generator 6 is thus increased thanks to the invention.
  • the temperature sensors were arranged in the supply and return lines 4, 8, 5 and 9. In practice, it often happens that the temperature sensor for measuring the temperature TV E of the flow line 4 of the generator circuit 1 is arranged directly in the heat generator 6.
  • the teaching according to the invention can also be used if one of the two temperature sensors for measuring TV E or TV V and / or one of the two temperature sensors for measuring TR E or TR V is suitably placed in the hydraulic switch 3.
  • the control and regulating device 11 is set up, the heating system in quasi-stationary operation or at to control or regulate slowly changing conditions in the manner described. While the start-up phase of the heating system or, for example, when changing from normal temperature to Lowering temperature, it can be advantageous not to use the control according to the invention, since it could then be counterproductive.
  • the increase in the volume flow V E in the first step for example by 10%, therefore causes warm water flows through the hydraulic switch 3 into the return line 5, since the volume flow V V through the heat consumers 10 remains unchanged.
  • the temperature TR E thus increases.
  • the volume flow V E is reduced again in discrete steps, for example in steps of 2%.
  • the warm volume flow V W is reduced again by the hydraulic switch 3, so that the temperature TR E decreases again.
  • the temperature TR E can only decrease as long as warm water is still flowing through the hydraulic switch 3 and is mixed with the cooler return water. If the temperature TR E no longer decreases, then the volume flow V E may no longer be reduced, since otherwise cold water would flow through the hydraulic switch 3 in the opposite direction.
  • This method has the advantage that only a single temperature sensor is required. It is particularly applicable when the volume flow V V required by the consumer is not subject to major fluctuations. The frequency with which the method is carried out is therefore preferably adapted to the needs of the users. In practice, this method is particularly interesting when the heating system has only a single heat generator 6.
