Definitions

  • the invention relates to a Temperieranlagenverteiler according to the preamble of claim 1 and a method for collecting and distributing heat transfer fluid according to the preamble of claim 12.
  • radiator heaters are fed with warmer liquids than underfloor heating or the tempering liquids heated by condensing boiler higher than by heat exchangers of solar systems.
  • Temperieranlagenverteiler known for connecting system circuits with flow and return lines for Temperier mickeiten with different temperature levels. From these documents it is apparent to build the distributor for this purpose from different temperature chambers.
  • system circuits can each be supplied with appropriately tempered heat transfer fluids and the returning heat transfer fluids are collected in appropriately tempered chambers, so that little heat energy is wasted unused.
  • the system circuits are consumer circuits and source circuits, where Consumer groups such as radiator heaters, underfloor heating or water heaters and source circuits condensing boilers, heat pumps or refrigerators may include.
  • the AT 411 190 B describes a heating system with a cylinder-shaped container as a distributor with several superimposed chambers.
  • the individual chambers are each tempered differently and have in the radial direction inlet and outlet connections for return or flow lines of the system circuits.
  • it can be fed with heat transfer fluid of a certain temperature level and the liquid return flow can be returned to a corresponding chamber.
  • the chambers are each interconnected by overcurrent connections with check valves. Due to the structure with different temperatures chambers results already discussed in terms of the prior art and known advantages.
  • An object of the invention is thus to provide a manifold having multiple temperature levels for temperature control systems with a smaller footprint and easy-to-install connecting lines for system circuits.
  • Another object of the invention is to improve a predictability of the temperature of the heat transfer fluid, so that undesirable temperature differences between the tempering liquids flowing into the system circuits are reduced.
  • An inventive Temperieranlagenverteiler is composed of a plurality of elongated, tubular containers, which are referred to as stages and provide different temperature levels of the heat transfer medium, constructed.
  • the steps each have three areas along their longitudinal axes.
  • At an inflow part which is designed to collect heat transfer fluids from the return lines of the system circuits, at least one, preferably a plurality of return line connections are arranged.
  • the inflow part is followed by a mixer part for the mixing of heat transfer fluids flowing from the inflow part into a discharge part, in particular temperature differences.
  • the discharge part following the mixer part has at least one, preferably a plurality of supply line connections and is therefore designed to distribute heat transfer fluid at a defined predefinable mixing temperature into the system circuits.
  • the heat transfer fluids collected in the inflow section are forcibly guided through the mixer before they can reach the supply lines of the system circuits via the outflow section. This ensures an improved mixing of the heat transfer fluids and thus an improved, more accurate predictability of the discharge target temperature.
  • the Temperieranlagenverteiler of three, four or five stages is constructed, which are arranged one above the other with spaced parallel longitudinal axes, wherein the three regions of adjacent stages are each arranged along the longitudinal axis in opposite order.
  • This allows a straightforward arrangement of overcurrent connections between the stages, i. from the inflow parts to the outflow parts of adjacent stages, respectively.
  • the stages are ordered by their respective target discharge temperature so that overcurrent flows are directed to the adjacent stages with the least temperature differential.
  • the steps may be formed as an elongated tube of, for example, circular, oval or rectangular cross-section, the longitudinal axes preferably being horizontally aligned.
  • a plurality of pipe sockets arranged as connections for return lines of system circuits sequentially sequentially along the longitudinal axis.
  • the pipe sockets designed as return line connections can protrude slightly into the interior of the step tube. This area of the step forms the inflow part.
  • the third fifth of the stage is designed, for example, as a mixer and for this purpose has an arrangement of flow line plates in the interior of the step tube, as is known to those skilled in the art, whereby the mixing of liquid flowing from the inlet part into the drain part is supported and thus the temperature is evened out.
  • the last two-fifths of the tube have pipe sockets as connections for flow lines of system circuits, which are sequentially arranged sequentially along the longitudinal axis.
  • the pipe sockets designed as feed line connections are flush with the step tube wall. This part of the step thus forms the drainage part.
  • the individual pipe sockets are generally arranged at right angles to the longitudinal axis of the step, wherein the cross sections of the pipe sockets are preferably formed to match the cross sections of the corresponding system circuit lines.
  • the overcurrent connections which are respectively disposed between the discharge parts and the supply parts of adjacent stages, may be tubular.
  • the distributor works as a hydraulic switch.
  • the overflow connections cause a Compensation of the mass flows, since the mass flows in the inflows of a stage do not correspond to the mass flows of the outflows. Due to the presence of the overflow connections, each system circuit has a closed circuit in itself, the flow resistance of which is caused only by the pipelines and various installations. The pumps installed in the system circuits only have to overcome this flow resistance.
  • the overcurrent connections have check valves or pressure compensation valves.
  • pressure equalizing valves for example, conventional spring-loaded pressure compensation valves can be used. But it is also possible to use pressure compensation valves, which are electronically controlled via pressure sensors. These pressure compensation valves have a passage direction in which they open above a certain, optionally adjustable, pressure difference. In the opposite direction these valves close in the manner of a check valve.
  • suitable liquids especially water
  • these can each be lined with insulating material, which compared to a one-piece, barrel-shaped design of the distributor with chamber partitions a lower energy loss can be realized.
  • the sum of the cross-sectional areas of the inflows approximately corresponds to the cross-sectional area of the tubular step
  • the skilled person corresponding to the dimensions and the number of stages and the pipe socket can adjust the flow rates and the number of system circuits.
  • the cross-sectional areas of the overflow connections are also designed by the person skilled in the art, so that a sufficient size for a short circuit is present. Even at high flow rates, the diameter of the tube-like steps can be kept small, so that the steps can be easily inserted through common door openings and through narrow aisles. Due to the parallel arrangement of the individual stages to one another and by arranging the system circuit line connections sequentially one behind the other along the longitudinal axes of the stages, the system circuit flow and return lines can be laid with little effort and space.
  • the in FIG. 1 illustrated Temperieranlagenverteiler 1 for collecting, mixing and distributing a heat transfer fluid has three stages 10,20,30 with predetermined discharge target temperatures of the heat transfer fluid.
  • the three stages are each formed as elongated, tubular containers with a longitudinal axis and - arranged in order of their respective outflow target temperature - arranged successively spaced, wherein the longitudinal axes of the steps 10,20,30 are parallel to each other.
  • Each of the stages 10, 20, 30 has an inflow part 11, 21, 31, a mixer part 13, 23, 33 and a discharge part 12, 22, 32, which follow one another along the longitudinal axis.
  • the mixer parts 13, 23, 33 of the stages 10, 20, 30 follow, in each case, the inflow parts 11, 21, 31, the mixer parts 13, 23, 33 being forced by the heat transfer fluid flows through in a predetermined direction.
  • the mixer parts 13,23,33 Strömungsleitbleche, so that the heat transfer fluid actively mixed when flowing through the mixer parts 13,23,33 and their temperature is made uniform to the discharge target temperature.
  • the overflow connections 5 connect the outflow part 12 of the first stage 10 with the inflow part 21 of the second stage 20, the outflow part 22 of the second stage 20 with the inflow parts 11, 31 of the first and third stages 10,30 and the discharge part 32 of the third stage 30 with the inflow part 21 of the second stage 20. Therefore, it is advantageous to successive stages each to arrange in a mirror-inverted manner, so that in each case below an inflow part of a stage, a drainage part of the adjacent stage follows and vice versa.
  • the overflow connections 5 each have a check valve or a non-return valve with a passage direction from the discharge parts 12, 22, 32 to the supply parts 11, 21, 31. Equally possible is a design of the overcurrent connections 5 with ball valves or motor valves for controlling overflow flow rates of the heat transfer fluid.
  • the steps 10, 20, 30 are in each case essentially the same size and functionally identical and have in the in FIG. 1 shown embodiment on a square cross-section.
  • the illustrated mixer sublimiting lines are shown purely for the purpose of illustration, for example, the steps can each be formed in one piece. However, it is also possible to form the parts of the steps separately and to arrange them further apart, wherein the heat transfer fluid is collected in an inflow part, passed through a mixer part and distributed via a discharge part into the system circuit lines.
  • FIG. 2 shows a sectional view of a formed as an elongated tubular container stage 10.
  • the stage 10 is divided into an inflow part 11, a mixer part 13 and a drain part 12.
  • three pipe sockets 15 are arranged for connection of system circuit return lines, wherein the pipe socket 15 each protrude slightly into the interior of the stage.
  • the arrows shown in the figure are intended to illustrate the flow directions of the heat transfer fluid.
  • the discharge part 12 which is designed to distribute the heat transfer liquid mixed to the outflow target temperature, three pipe stubs 17 are arranged for the connection of system circuit supply lines.
  • the pipe sockets 17, which are in the form of flow line connections, close in particular flush with the stepped container wall. Furthermore, the inflow part 11 and the outflow part 12 each have an overflow connection connection 5 with a check valve 6, via which they can be connected to outflow or inflow parts of adjacent stages.
  • stage 10 in which the collecting of the refluxes locally separated from the distribution of the heat transfer fluid in the flow lines of the system circuits, a defined flow direction results for the heat transfer fluids. This allows an improved mixing of the heat transfer fluids, so that a target discharge temperature can be specified more accurately.
  • FIG. 3 shows an embodiment of a Temperieranlagenverteilers 1 according to the invention with two stages 10,20 shown in a 3-D view.
  • seven return pipe connections 15, 25, designed as pipe sockets are arranged for collecting the heat transfer fluids flowing back into the distributor from the system circuits.
  • the discharge parts 12,22 are formed as elongated, round tubes, each with seven flow line connections.
  • the mixer parts are flowed through by the heat transfer fluids prior to distribution in the system circuits.
  • overcurrent connections 5 are arranged to compensate for the mass flows.
  • the number and the cross-sectional area of the stages can be adapted by a person skilled in the art in accordance with the number and type of system circuits present.
  • FIG. 4 shows a schematic representation of a temperature control system with an inventive distributor and connected consumer circuits 65,66 and source circuits 61,62,63,64.
  • the stages are arranged one below the other according to their target discharge temperature, with the highest outflow setpoint temperature being mixed in the uppermost stage.
  • the source circuit 61 has, for example, a condensing boiler for oil, gas or biomass, wherein the heat transfer fluid is usually heated to a temperature of more than 75 ° C.
  • the return line of the system circuit 61 is thus connected to the upper stage 10 with the highest target discharge temperature. Since a condensing boiler is most efficient when there is a large difference in temperature between supply and return, which also applies to district heating, the supply line of this system circuit to the drain part 31 of the lowest stage 30 with the lowest run-off target temperature connected.
  • the source circuit 62 has, for example, a heat pump or a heat exchanger of a solar system.
  • the headers, which are fed from the discharge part 32 of the lowest stage 30 are heated by the heat pump or the heat exchanger of the solar system to temperatures of about 25-40 ° C.
  • the refluxes are thus directed into the inflow part of the middle stage 20.
  • a log wood boiler with thermal return increase is shown as a further producer in the source circuit 63.
  • the flow temperature may be about 35 ° C, which is why the flow line is connected to a flow line connection of the discharge part 21 of the middle stage 20.
  • the heat transfer fluid is heated to about 60 ° C. The return is thus connected to the inflow part 11 of the upper stage 10.
  • the source circuit 64 has, for example, a buffer storage, which is fed with heat transfer fluid having a temperature of about 60-70 ° C, which is why the supply line to the discharge part 12 of the upper stage 10 is connected to the highest target discharge temperature.
  • a return line of the buffer memory is connected to the inflow part 11 of the stage 10, via which line the heat transfer fluid from the buffer store, which has the highest temperature, is returned to the distributor.
  • Another return line is connected to the inflow part 31 of the lower stage 30, whereby the already most cooled heat transfer liquid can be returned to the manifold via this line.
  • a system circuit 65 with a radiator heater and a system circuit 66 are shown with a floor heating example.

  • the underfloor heating is fed with heat transfer fluid from the discharge section 21 of the middle stage 20 at a temperature of up to 38 ° C.
  • the cooled refluxes are returned to the inflow part 31 of the lowest stage 30.
  • the inflows which inevitably all flow through the mixer part, can be mixed exactly to a predefinable temperature.
