Definitions

  • Distribution unit for heating and / or cooling systems working with a flowable heat exchange medium for connecting a plurality of branch lines to main flow and return lines, with a plurality of identical or similar distribution elements which are fitted with fittings of a controlled system such as shut-off, throttling, regulating and deflection elements, feed pumps and.
  • a controlled system such as shut-off, throttling, regulating and deflection elements, feed pumps and.
  • the task of these individual supply and return groups is to supply the medium flowing through, regulated and controlled according to the requirements, to the consumer units.
  • thermal systems such as Central heating systems demand that the heat generated be passed on to the heat consumer as quickly as possible and without losses.
  • the distributor sticks and the vertical individual groups e.g. in central heating systems in the boiler room, pipe insulation against heat loss must be provided in accordance with the standard.
  • the valves, pump bodies, regulator bodies, flanges and sleeves are insulated against heat loss almost exclusively in large systems. In smaller thermal systems, this important insulation is mostly dispensed with for all economic reasons and because of the difficult to install total thermal insulation across all fittings.
  • a very essential heat-conducting intermediate element in the form of heat distribution systems is connected between heat generation and heat dissipation, which in known systems does not meet today's requirements for saving thermal energy. It is also not possible to meet the requirements with conventional materials and structures at the construction site.
  • the control group of a medium-sized hot water central heating system includes: 2 flow valves, 2 return valves, 1 control valve, 1 circulation pump, a total of 6 valves for each control group.
  • each central heating system has two control groups with 12 valve bodies, which lead to a heat loss of 1080 watts / h (with non-insulated valve bodies).
  • the object of the invention is to further develop this unit in such a way that the flow processes are economically improved and the losses in thermal energy are substantially reduced with simplified and less expensive production.
  • the distributor elements of individual flow circuits are combined to form uniform distributor columns with integrated fittings and at least one flow chamber and one return chamber.
  • the entire distribution unit can be designed to be extraordinarily compact with a small volume and a correspondingly small outer surface, and therefore to be insulated from the outside as a whole in a simple manner.
  • the heat-emitting surfaces are further reduced by the fact that almost all of the fittings required for the different control and regulating processes are accommodated within the walls of the individual distributor columns, and therefore cannot themselves emit any heat to the outside. It is therefore generally not necessary to pull in any connecting lines between the immediately adjacent column chambers. Since the flow and return chambers directly adjoin each other, only the heat shift necessary anyway in the respective flow circuits occurs by raising the return temperature before it is introduced into the boiler.
  • the individual distributors can be almost completely completed by the manufacturing company. They are only to be attached to a bracket, with each other and with theirs To connect external connections. In this way, manufacturing on an industrial basis is made extremely easier and cheaper, and yet it can be adapted to a wide variety of requirements.
  • the distribution columns can also be designed so that the flow processes can largely run optimally against low resistances, and the heat transfer volume can be very precisely and economically on the heat generators, consumers and. Vote. Therefore, pumps, regulating and control devices, valves, heat protection and. Dimension particularly economically. As a result of the smaller overall surface, the insulation is simplified overall and the heat losses are reduced.
  • the entire unit can be precisely aligned by bumping against the ceiling, so that the pipe connections on the distributor unit and on the building can also be assigned to each other exactly at the specified height. So you can lay it before the unit is delivered and installed. Its manufacture is in turn simplified by the compact arrangement regardless of how it is constructed and controlled.
  • the entire unit can easily be provided with a dense, heat-insulating covering and also installed in the building, protected against heat loss.
  • thermal insulation can be carried out after the panel has been completed, in principle also at the construction site, but preferably during pre-assembly, and in the last method in particular, it is recommended that the hollow columns be prefabricated, at least on the outer surface of the panel, with a solid wall provided 1Värmedämmlage with openings only for the necessary connection of display and control elements.
  • the individual distribution columns which can also be oriented horizontally, can basically be arranged in one piece in a common hollow plate which is divided into individual, adjacent flow channels by numerous partition walls.
  • this can result in heat transfers between switched on and switched off circuits.
  • the double-chamber hollow columns assigned to each flow circuit are expediently provided at intervals between them and insulated from one another, in particular under thermal insulation layers firmly attached to their side surfaces.
  • each distributor column can thus be encased circumferentially with an insulating shell, which reduces the heat emission practically in all directions.
  • cross distributors for total flow and return are expediently connected, in particular molded on.
  • Such cross distributors can also be prefabricated and, if necessary, connected to corresponding transition openings in the hollow columns with clamp connections, but they can also be formed in one piece.
  • Such a cross distributor can be attached at the front end at the upper end and another at the front end at the lower end, that is to say it can be completely classified into the outline shape of a panel.
  • the distributor assembly should have at least one main distributor column arranged in its plane along the individual distribution columns for passing through the entire heat transfer medium for all branch lines to be connected. In this way, a presetting or regulation in the entire heating or cooling circuit of the system is possible without this causing significant heat losses or appearing to be disruptive to the outside. Even though the same cross-sections are normally sought for the individual hollow columns and their chambers, it can be done form these chambers within the distribution unit of different widths and thus adapt them to the volume of the flowing media.
  • a thermostatically controllable feed pump can be installed in each of the distribution columns, in particular the connecting parts for the drive motor mounted on the outside being led through the front insulation. You can activate the individual flow circuits depending on the heat requirement or influence the temperatures of the flowing media.
  • connecting pipe sockets can be led through the insulating sleeve to the outside and preferably surrounded by a molded insulating jacket socket. After the pipe connections have been made, the insulation only needs to be completed at a distance from the hollow column.
  • Each distribution column can be assigned heat transfer means for transferring heat from a column chamber, through the level of a partition, into the adjacent column chamber. While this usually made separate, mostly exposed line connections necessary, there is only one easy barrier to overcome. In this way, the return temperature can be raised before it is introduced into the boiler, so that the dew point in the heat generator is not exceeded
  • At least one through-opening can be provided between the two column chambers, in particular in the partition, and this can be assigned adjusting means for setting or regulating the flow through this through-opening.
  • the passage opening can also be configured as a bypass, in particular channel-shaped, connecting both column chambers with at least one shut-off element, in particular a throttle element.
  • Flow guide means for guiding the flow in the column chamber / downstream of the passage opening can also be assigned to the passage opening.
  • these guide means for example lamellae, can have guide elements provided in the downstream column chamber upstream of the passage opening and oriented along the column chamber for largely laminar introduction of the main flow and downstream of the passage opening to the longitudinal direction of the column chamber with differently inclined vortex and / or mixer guide elements.
  • the two partial flows can be brought together and into each other in the shortest possible way in the desired manner and then mixed thoroughly, so that the possibly under a short distance from the mixing elements and therefore in a matter of seconds. can measure the temperature required for further control processes. In this way, the length of the controlled system or the columns can be shortened.
  • the or one further passage opening between the two column chambers is preferably assigned a thermostatically controllable mixing valve which automatically adjusts the guide flow according to a sensed temperature and can optionally be controlled electronically.
  • the mixing valve is expediently designed as a multi-way valve which is connected to at least one column chamber by means of two separate connections. In this way, a four-way valve can be fitted in the passage opening and connected to the upstream and downstream parts of both column chambers.
  • a separate shut-off device for changing the function can also be assigned to a valve connection as a three-way valve. It is even better to bridge the multi-way valve in a column chamber, in particular the return chamber, by means of a short-circuit connection and to design the shut-off element as a switching element that either blocks the short-circuit connection or the valve connection.
  • the walls of the four-way valve can be divided into two pillar chambers by means of the connections thereof, the end parts of the two pillar chambers which are provided at a lateral spacing from one another expediently star-shaped. mig start from the four-way valve.
  • At least one distribution column can also have a heat meter with temperature sensors in both column chambers.
  • the heat transfer means in divided longitudinal shafts of both chambers of the distributor column, at least in the main distributor column. At least in the divided longitudinal shaft of one of the two column chambers, the or a feed pump can then be attached, which can be connected to its shaft on the suction or pressure side.
  • the two longitudinal shafts can also be delimited at one end by a common deflection bend which delimits the opening. It is therefore possible to start a reversing control by switching on the pump, which transfers part of the flow from the flow chamber into the return chamber on a U-shaped loop.
  • a mixing device for mixing the shaft flow with the remaining chamber flow should then again be provided, if possible.
  • a further embodiment of the invention is characterized by the design of the heat transfer means as thermally connecting the two column chambers, in particular an intermediate partition arranged therebetween, which essentially has a fluid-tight passage and has large heat exchanger surfaces in both longitudinal shafts.
  • Such heat transfer means are known per se and do not require any special energy supply in order to improve the heat transfer, but they can be activated by switching on a pump on at least one side, since in this way the heat gradient and thus the heat transfer current is increased. In any case, it is not necessary to divert the heat transfer medium from one chamber to the other, but only to heat it up (or cool it down) through the partition.
  • heat transfer elements which, in the manner of "heat pipes", each have a tubular hollow body which is filled with a flowable, rapidly reacting heat exchanger medium or refrigerant, the condensation temperature of which is somewhat above the temperature of the return chamber. A flow then forms in the upper part opposite to the flow in the lower part of the transverse hollow body, the initially vaporous refrigerant condensing in the return chamber, flowing back into the supply chamber and evaporating there again by heating at the higher temperature.
  • heat transfer elements include known from "Gesundheits Ingenieur, 1976, pp. 164-167" and need no further explanation.
  • the individual distributor columns can be provided with holding rails to be fastened to a supporting wall, in particular through a thermal insulation layer, which are preferably formed by laterally projecting connecting flanges and then, for example, with such a distance from the cor pus of the distributor column can be angled so that they grip around the edge of a thermal insulation layer and hold it.
  • thermal insulation layers of adjacent distribution columns can also be spaced apart for an intermediate space for accommodating additional devices such as electrical lines and installation parts. As a rule, these rooms do not have to be stripped, but can simply be closed off with a cover strip to the outside.
  • the connecting flanges are expediently formed in a Z-shape with overlapping edge parts. The same screws can then be used for adjacent columns.
  • U-shaped guide rails are provided for removable parts of the device, which can be easily and quickly attached and, if necessary, replaced.
  • the distribution unit is also adapted to the side of the unit with the same height (or length) and depth, in particular integrated into this, a control and regulation column with individually removable inserts for measurement, control and regulation groups. At least towards the panel, this column can also be shielded by a thermal insulation layer.
  • the invention further pursues the task of designing the cross distributor arrangement in such a way that the individual column chambers can be easily connected, and this is done according to the invention primarily in that both cross distributors have flow channels penetrating the distributor columns within their outer surfaces. These flow channels can then be arranged as desired within the distribution columns so that they can be connected to each of the two column chambers can be connected without any special throttling effect. This is relatively easy if you choose different or irregular cross sections, but even with regular cross sections this can be done without any particular difficulty.
  • connection openings are provided between each flow channel and at least one column chamber of a distributor column. If it is advisable for manufacturing reasons, such connecting openings can be provided for each of the two chambers, and one of the openings is closed. It is essential, however, that the opening cross-section for the individual flow paths can be adjusted as required for the same chamber volume and thus the respective volume flows can be preset in relation to the expected heating or cooling output.
  • the flow channels of the cross distributors can in principle be permanently integrated in the distributor columns, but they are preferably formed by individual pipe elements which can be sealed in the wall of the hollow columns.
  • the flow channels a circular cross section, in particular to form them by at least partially cylindrical tube sleeves, regardless of whether such tube sleeves are now welded or soldered to the distributor columns or can be interchangeably sealed in them.
  • the wall of the flow channels is expediently provided with a thread on the inside, which can serve various purposes.
  • the closure elements can be designed as throttle elements attached to the flow channels, in particular screwed into their walls.
  • These can be throttle bushings that can be adjusted in the longitudinal direction or pivotable throttle slides.
  • the setting is usually made before assembly, but can also be done subsequently using a nipple wrench or the like if the throttle elements have corresponding inwardly projecting cams.
  • the transverse distributors are attached to one and preferably the lower end of the column, it may still be expedient to mount them in the middle of the distributor columns projecting from there towards their outside ends to the connecting lines provided. Practically, this means that two column chambers of different, opposite, protruding columns are connected to a connection point. It must then be decided on a case-by-case basis whether the two column chambers can remain in flow connection or whether at least a limited separation is provided in the area of the cross-distributors, for example in such a way that the distribution columns are subdivided there and the two chambers through separate openings on the same flow channel or connects to different flow channels.
  • adjacent chambers can also be selected so that two hollow columns are connected to a common partition. This applies to two flow chambers, but also to the flow and return chambers of the same or a temperature-comparable flow circuit. Either the temperatures in the adjacent chambers are then at least approximately the same, or an influence which is usually sought there is achieved.
  • a double panel is formed from individual elongate structural units with a housing box which is in the longitudinal direction through one another intersecting partitions is divided into at least four sub-chambers open on opposite sides. In each such unit, two or four flow circuits can then be connected, ie the width of the panel always remains relatively small.
  • cross distributors may only have to be provided in a first panel, partial chambers being connected to subchambers of the other panel arranged in the same way by means of openings in the common partition. So you can also install one cross distributor in the first panel and the other in the second panel.
  • a complete interior arrangement of all fittings can only be achieved if you commit yourself to certain fittings. However, due to the extensive technical development, this is not easily possible with some fittings. It may therefore be appropriate there to provide only the necessary connecting means, such as wall openings, pipe sockets or the like, in order to be able to mount the fittings in question on the outside. But it is also important that this external arrangement is only prepared and then optionally carried out as required, d. H. the distributor unit is normally supplied with fittings installed on the inside, but some of these fittings can be replaced during installation or afterwards by other fittings arranged on the outside.
  • An external arrangement again increases the heat losses.
  • This can be counteracted by a heat-insulating shield covering the space for external fittings.
  • This can be a hood that can be fitted as a whole, or isolated side walls of the panel are preferred and the opening is then closed by one or more door elements.
  • the one-piece version of the dividing column is sought, it may / may be advisable to make this column at least at one end towards such a length that the fittings in the column chambers are made accessible by lifting off, in particular, a single wall part. You then get by with fewer and easier interruptions in the column chambers. Above all, however, the assembly is simplified, since the fittings can be installed in the housing-fixed or in the removable wall part, depending on the expediency.
  • the simplest design of the subdivision is seen in the design of the removable wall part as a front cover, which is preferably attached to a one-piece double tub.
  • the distributor columns have at least two housing shells which are formed on opposite sides from a common contact plane and are held against one another in this contact plane.
  • This shell design has the particular advantage that you get by with a few, largely prefabricated housing parts and gain greater freedom of movement when attaching the internal fittings to one or the other housing part.

  • the double trough 190 is rounded at its rear longitudinal edges, and according to FIG. 22 a double trough 290 is formed by two troughs 97, which are partially cylindrically rounded on the rear.
  • both pillar chambers 11, 12 being circular and delimited by two double shells 390, 391, which are sealed against one another in a common contact plane and sealed by screws and are formed approximately symmetrically from this contact plane to two semi-cylindrical channels 971.
  • the semi-cylindrical grooves can basically merge into one another.
  • the channels 971 of the double shells 490, 491 are arranged with a larger spacing and are connected by flanges 100 drawn in between them which are more or less wide.
  • the partition elements 109 lie close together, the partition elements 209 according to FIG. 23 smaller and, according to FIG. 24, larger spacing.
  • the distributor column 101 shown there is essentially formed by a double-shell housing 104, to which two column-shaped pieces 107 and 108 are fastened by means of double-thread coupling bushings 106.
  • the mixing valve 136 designed as a four-way valve, the flow chamber 11 and the return chamber 12 are divided into upstream subchambers 11b and 12a and downstream subchambers 11a and 12b. These subchambers are each connected to the four-way mixing valve 136, they start from it in a star shape.
  • a passage 131 used as a bypass with an infinitely adjustable adjusting member 132 now extends between the two lateral subchambers 11a and 12a. In this way, the circulation flow between the two subchambers 11a and 12a in particular can be controlled.
  • connection d is bridged by a short-circuit channel 12c drawn between the subchambers 12a and 12b, in which a switching element 118 with its segment in the position shown shows the connection d and in one other position the short-circuit channel. 12c locks.
  • the four-way mixing valve 136 can be converted into a three-way mixing valve.
  • the heat exchange medium can be simply conducted up there. It becomes more difficult already at the transition from the return sub-chamber 12b to the transverse collector 172 located below.
  • the connecting line 119 must therefore, as can be seen above all in FIG. 26, be diverted around the transverse distributor 171.
  • a heat meter 120 which is primarily arranged in the return line, determines the flow and return temperature using temperature buttons 121 and, in conjunction with the amount of medium flowing through, records the amount of heat emitted between the two temperature buttons and normally feeds it to a recording device.
  • 126 denotes a thermometer
  • 127 a pressure gauge connection
  • 128 is an emptying nozzle, which can possibly also be equipped with an emptying hook.
  • the two housing shells 10, 110 can be braced against one another with sufficient sealing security by the screws 96 attached in different lateral flanges, possibly also by means of screws inserted through the flow paths. It is of course also possible to use a separate clamping frame for this purpose, which extends from the outside to the contact plane 98 acts on the housing shells.
  • the individual distributor columns can only be coupled to one another by the nipple sleeves 178 drawn into the transverse distributor 171 and transverse collector 172. They are expediently attached with circumferential spacings in an outer housing 124, the spaces being filled with thermal insulation material. Slidable throttle bushings 182 are also used here at the connections of the column chambers.
