Definitions

  • the present invention relates to a manifold for a heating or cooling system, with an elongated, cuboid, in operation horizontally arranged housing in which a flow chamber with multiple flow ports and a return chamber with multiple return ports of secondary circuits are provided, and with a hydraulic switch for hydraulic Decoupling a connected to a flow connection and a return port of the switch primary circuit of the secondary circuits, wherein the hydraulic switch is integrated into the housing and comprises a fluidly connected to the flow chamber and the remindlaüfhunt soft space into which the supply port and the return port of the switch open in a lower part of the housing as a switch chamber is provided over at least part of the horizontal length of the housing extending turnout chamber and wherein the turnout chamber at two horizontal vonein other spaced points on the one hand to the flow chamber and on the other hand fluidly connected to the return chamber.
  • the DE 20 2004 019 873 U1 shows a distributor device for a operated with a liquid medium circuit of a heat supply system, in particular a hot water heating system, with a wall boiler as a heat source and with mixed and / or unmixed hot circles, wherein the distribution device comprises in a hollow profile a flow chamber and a return chamber.
  • the distributor device comprises a further chamber as a hydraulic switch, in which the boiler supply and -Rücklauf ein open and which in turn is connected to the flow chamber and the return chamber of the distributor device.
  • the flow chamber, the return chamber and serving as a hydraulic switch further chamber are arranged in three levels one above the other in the hollow profile. This leads disadvantageously to a relatively large height.
  • the flow connections and return connections for the heating circuits are at the top of the distributor device in a line.
  • the return connections are designed as pipe sections which are guided sealingly through the supply chamber and extend as far as the return chamber lying in a middle plane of the distributor device.
  • a flow connection from the switch chamber to the topmost flow chamber is formed as a pipe piece which is sealingly guided by the lying in the middle plane return chamber. This results in a high manufacturing and assembly costs, which makes the distribution device expensive.
  • the flow connection and the return connection for the boiler at the switch chamber are relatively close to each other, which leads to the risk of undesirable and efficiency reducing short-circuit currents in the boiler circuit.
  • the DE 42 34 960 C1 discloses a manifold with hydraulic decoupler, which is integrated between the flow chamber and the return chamber in the housing of the manifold.
  • a recess defines in connection with the housing walls a decoupling space in which the flow connection and the return connection of the primary circuit of a heating system open.
  • a disadvantage is considered in this known manifold, that it can easily lead to an undesirable circulation flow in the primary or boiler circuit, whereby the heat generated is not transferred to the desired extent to the secondary or heating circuits.
  • This has the consequence that the theoretically available heat output from one or more boilers can not be supplied in full to the heating circuits with heat consumers provided therein.
  • the reason for this is, in particular, that the flow connection and the return connection of the primary circuit to the decoupling space are relatively close to each other and that the flow of heat transfer fluid entering through the flow connection in the decoupling space, is directed towards the return port of the primary circuit and so preferably in the return, ie returned to the boiler.
  • the return temperature of the heat transfer fluid that reaches the boiler is thereby undesirably high, which is detrimental to the performance of the heating system.
  • the object is to provide a pipe distributor of the type mentioned above, which avoids the disadvantages set out above and in which is achieved in particular that generated by one or more boilers heat output or a cooling power generated by one or more refrigerators fully in the associated heating circuits or cooling circuits and thus a high efficiency of the heating or cooling system is guaranteed overall.
  • the manifold is intended to function as a hydraulic separator for decoupling the circuits fully comply.
  • the switch chamber has a compact size, in particular a low overall height, because the flow chamber and the return chamber are adjacent to each other in a plane.
  • the production is advantageously simple, because neither the flow ports nor the return ports must be passed through each unrelated chamber, as is the case with manifolds arranged one above the other flow and return chambers.
  • manifolds arranged one above the other flow and return chambers.
  • the pipe manifold according to the invention short-circuit currents in the primary circuit, here the boiler or refrigerating machine circuit. This ensures that the full heating power or cooling capacity gets into the heating circuits or cooling circuits and that while the boiler or chillers work with a high efficiency, because a large temperature difference between their supply and return is achieved.
  • the pipe distributor according to the invention easily offers the possibility of complying with a fluidically advantageous, relatively large distance between the feed connection and the return connection of the switch chamber.
  • the switch chamber is connected via two spaced flow connections on the one hand with the flow chamber and on the other hand with the return chamber, mutual disturbances of the flow and return flows in the manifold are basically excluded.
  • a pipe distributor is provided with the invention, which ensures high efficiency of the heating or cooling system, which combines the functions of the manifold and the hydraulic switch space-saving and reliable in itself and can be manufactured inexpensively.
  • a first embodiment provides that the intermediate wall is a wavy wall running and that the flow connections of the flow chamber and / or the return ports of the return chamber each open from above through the top wall into its associated chamber.
  • This corrugated partition offers the possibility not only to arrange all supply and return connections together at the top of the housing, but also to place all the supply and return connections on a straight line, with all supply and return connections only pass through the top wall. This results in a moritary-friendly layout and a very clear layout.
  • the flow ports of the flow chamber and / or the return ports of the return chamber each open laterally into its associated chamber.

  • the horizontal length of the housing is correspondingly larger and then it is sufficient a horizontal length of the switch chamber, which is smaller than the horizontal length the housing or the flow chamber and the return chamber. It is then envisaged that the switch chamber extends only over a part of the horizontal length of the housing and is fluidly connected to the flow chamber at or near a first end face of the switch chamber and with the return chamber at or near a second end face of the switch chamber. It is always essential that the horizontal length of the switch chamber is sufficiently large to avoid unwanted short-circuit currents in the primary circuit.
  • the flow connections and between the switch chamber on the one hand and the flow chamber and the return chamber on the other hand are formed by a respective opening in the separating chamber of the flow chamber and the return chamber separating wall.
  • the flow connections are very easy to produce, because they only require the attachment of openings in the partition or only a shortening of the partition is necessary in such a way that it ends at a distance from the two ends of the housing.
