Definitions
- the present invention relates to a fitting assembly for a central heating system which comprises substantially a heat source, a plurality of heater units such as radiators, and a system of supply and return conduits between the heat source and the heater units.
- the supply and return conduits are incorporated into the finishing floors during the building of a private house or an industrial building and, at suitable places, fitted with connector pipes that are connected to the main conduits for example, via tees. Then the finishing floor is poured and further finished.
- the connection pipes for the central heating that at a later stage must be connected to the heater units often protrude from the floor of a private house or building in progress. These pipes often cause problems, because they are not noticed during the building process, people trip over them or they are damaged in other ways, with detrimental consequences.
- the connection of the pipes to the various heater units is time-consuming and, therefore, expensive, too, as all individual connections must be made to size.
- group distributors are used in this system, i.e. several connections to heater units must be led to these group distributors, which demands relatively a lot more additional material and, moreover, increases the risk of leakage, etc.
- European document EP-B-0934492 describes a connector box for heating installations, such as radiators and, in particular, under-floor heating, which comprises a housing with a cover element that is provided with holes for the connection of supply and return conduits for the central heating installation. Furthermore, the described device comprises a bypass, and control elements to control the branching of the flow through the heater unit or to short-circuit the flow when no heating effect is required of the heater unit.
- EP-A-0695916 discloses a metal or plastic distributor body which is able to be mounted in a twin conduit (flow and return) central heating system so as to allow the out and return flows to pass through the distributor block, and this block includes two tapping passages for flow pipes to and from a heater unit such that one of the tapping pipes communicates with the nearer of the two (flow and return) conduits while the other is able to pass in sealed manner through that nearer conduit and communicate with the remote one of the two (flow and return) conduits to permit flow linking the flow and the return conduits by way of the heater unit and the control valve which will be at the heater unit.
- This is a fixed configuration distributor block.
- a fitting-assembly which comprises (a) at least one fitting-unit incorporated into the system of supply and return conduits, the or each said fitting unit comprising a connection point to a supply conduit and a connection point to a return conduit of the supply and return system between the heat source and the heater units, and (b) at least one "fitting-block" that is functionally connected to a respective said fitting-unit and includes a housing in which is contained at least one supply chamber having a connection for a supply conduit from the fitting-unit and a return chamber with at least one connection for a return conduit to said respective fitting-unit, said supply chamber further comprising a connection for coupling to the inlet of a heater unit of the central heating system, and said return chamber further comprising a connection for coupling to the outlet of a heater unit of the central heating system.
- a fitting-block for a central heating system comprising a housing with a supply chamber having at least one connection for a supply conduit from the central heating system and a return chamber with at least one connection for a return conduit to the central heating system, the supply chamber further comprising a connection for coupling to the inlet of a heater unit of the central heating system, and the return chamber further comprising a connection for coupling to the outlet of a heater unit of the central heating system.
- This fitting-block can be part of the complete fitting- assembly of the first aspect defined above, by connecting it to a fitting-unit of this assembly.
- the fitting-block can, however, also be used separately by connecting it in a different way to the supply and return conduits of the central heating system.
- the fitting-block is connected directly to the inlet and/or outlet of a heater unit of the central heating system. More preferably, the fitting-block is fitted to the outlet of a heater unit. Then the connection between the fitting-block and the inlet of the heater unit can be realised easily, too, and can also be standardised. If desired, the fitting-block on the heater unit can be prefabricated, after which the supply and return conduits of the fitting-block need only be connected to the first fitting-unit of the fitting- assembly according to the first aspect of the invention, or otherwise.
- the fitting-block is fitted crosswise to the heater unit, with the result that the connections to the supply and return conduits of the central heating system are in principle always short, without the need to arrange the pipes in an untidy X-shaped crossover between a fitting unit and a fitting block.
- the fitting-assembly according to the invention allows replacement of the pipe system incorporating group distributors, which is predominantly used up to now, and the resulting multiple connections, by a double ring conduit system along the walls or windows where the heater units, such as radiators, are intended and to provide these ring conduit systems at the locations of the intended connections with tees, in order to form in this way the fitting-units as defined above.
- the fitting-units are placed into a box, a cabinet or a similar enclosure that is preferably incorporated into the floor and provided with a cover plate in which, if required, one or more recesses are made for connecting conduits with a fitting-block.
- the supply and return conduits of the central heating system are fitted with jacket pipes, for example, protected ribbed pipes, which are connected to the boxes, cabinets, etc. of the fitting-units.
- jacket pipes for example, protected ribbed pipes
- the conduits are preferably connected to the tees of the fitting-unit by means of push-in fittings or compression fittings. This also applies to the connections to the fitting-block, usually except the tailpiece, which is, for example, connected to the bottom (outlet) of the heater unit by means of a compression fitting joint.
- the fitting-block comprises a changeover device enabling reversal of the flow direction within the block.
- This allows fitting of the heater units with the fitting-blocks turned either "clockwise” or “anticlockwise”, obviating the need for complicated facilities or crossover connection pipelines.
- the changeover device is fitted in the housing of the fitting-block in such a way that it can be rotated, and preferably in such a way that the device can easily be operated from the outside, for example, by one or several setscrews that are connected to the changeover device by means of a spindle.
- the changeover device is implemented in such a way that the flow can be not only reversed, but also stopped, or that the flow rate can be controlled by rotation.
- the fitting-block further comprises one or more measuring and/or control means for controlling one or more physical parameters in the block, such as, for example, the flow rate and/or temperature.
- Figure 1 is a front elevation of a fitting-block according to the invention.
- Figure 2 is an end elevation of the fitting block of Figure 1.
- Figure 3 is a schematic cross section of a fitting-block embodiment according to the invention, taken on the line Ill-Ill of Figure 2.
- Figure 4 is a schematic cross section of a fitting-block embodiment according to the invention, taken on the line IV-IV of Figure 1.
- Figure 5 is a sketch of a fitting-block according to the invention, connected to the bottom part of a central heating unit.
- Figure 6 is a sketch of an embodiment of a first fitting-unit ("poured-in box") that is part of a fitting-assembly according to the invention. It is to be noted that the same reference numbers in the various Figures refer to the same elements, which, however, are sometimes shown in a different view.
- a fitting-block also called “bottom block” which comprises a housing 1 with openings 2 and 3 for connection to a supply pipeline and a return conduit respectively of the central heating system.
- Housing 1 furthermore comprises an opening 4 for connection to the inlet of the heater unit associated with the bottom block, as well as at the rear a tailpiece with an opening 6 for preferably direct connection of the bottom block to the outlet of its heater unit.
- the bottom block is preferably fitted crosswise to the heater unit, as can be seen best in Figure 5.
- two cover caps 5 are indicated that are fixed detachably to the housing and that provide access to the control elements that control a flow changeover device 7 (please refer to Figures 3 and 4).
- FIG. 3 provides a clear schematic view of the most essential parts of the fitting- block. Besides the already discussed parts - i.e. housing 1 , openings 2, 3 and 4 for connection to the various conduits, and cover caps 5 - there is here shown the rotatable flow changeover device 7 having a central chamber partitioned by a separating wall 11 , which allows reversal of the flow direction in the housing 1. Rotation is achieved by means of a control element 28, for example a setscrew, which is connected to the changeover device 7 by means of a spindle 8.
- a control element 28 for example a setscrew
- connection conduits 21 that are connected to housing 1 preferably by means of push-in fittings 22, a supply chamber 31 , and a supply chamber 32, which are functionally connected to the inlet of a heater unit and to the outlet of a heater unit respectively.
- the central heating water flows from the conduit system into the housing 1 through inlet opening 2 to supply chamber 31.
- Changeover device 7 occupies such a position that the water flows further past separating wall 11 and leaves the housing at outlet opening 4. Opening 4 is functionally connected to the inlet of a heater unit, as can be seen best in Figure 5. From this heater unit the water arrives again back at the housing 1 through the tailpiece opening 6. Then it flows through changeover device 7 to return chamber 32 and leaves the housing via opening 3 to a return conduit of the central heating system.
- the change-over device is rotated to a different position the flow direction can be reversed, so that the water does not flow into housing 1 at 2, but at 3, and then flows through the changeover device to leave the housing at opening 4.
- opening 4 is functionally connected to the inlet of a heater element and the water arrives again in the housing 1 via the outlet of the heater element and the rear opening 6 of the fitting-block, and then flows through the changeover device 7 out to the return conduit of the central heating system via the opening 2, which now functions as an outlet opening.
- the changeover device 7 the fitting-block is able to function both in the "clockwise” and the “anticlockwise” direction and there is no need for adaptations to the conduits.
- Changeover device 7 can also be set to such a position ( Figure 4) that the flow through the device is completely stopped, i.e. in both flow directions, or only blocked from the tailpiece or only blocked to the inlet of a heater unit. In all these cases it is possible to uncouple the heater unit without the need to drain the entire central heating system (in case of a complete shut-off by changeover device 7, the stop cock at the heater unit inlet or - as the occasion arises - at the heater unit outlet must be closed as well).
- Changeover device 7 is preferably fitted at both sides with a spindle 8 and a control element 28 (for example, a setscrew), so that the changeover device can be easily controlled from one of both sides.
- FIG. 4 provides a further illustration in side view of the functioning of the changeover device 7, the embodiment of separating wall being illustrated in more detail.
- Figure 4 shows the changeover device 7 rotated through 90° with respect to the configuration shown in Figure 3 in that whereas Figure 3 shows on the one hand the inlet opening 2 communicating with the outlet opening 4 to the heater unit and on the other hand the outlet opening 3 communicating with the return opening of the tailpiece 6 which communicates with the outlet from the heater unit, the separating wall shown in Figure 4 is arranged vertically and the diametrically opposed openings in the core of the changeover device 7 are no longer in register with either the outlet opening 4 or the elbow from the tailpiece 6.
- Figure 4 shows a situation where the heater unit is isolated from the central heating system whereas Figure 3 shows the heater unit in full communication with the central heating system.
- Rotation of the changeover unit core 7 from the Figure 4 position through less than a right angle will provide the desired communication between the inlet openings 2 and 3 on the one hand and the respective openings of the outlet opening 4 and the tailpiece 6 on the other hand but with a reduced flow cross-section so that some degree of flow control is achieved.
- Figure 5 shows an embodiment of a fitting-block fitted to the bottom of a central heating heater unit. Opening 4 of the fitting-block is connected to inlet 14 of the heater unit by means of a pipe, this inlet usually being governed by a control valve (for example, a thermostat valve). It is conceivable for the flow changeover device to be modified to allow for other shut-off and/or flow-permitting modes. Such a possibility is not illustrated in the drawings.
- a control valve for example, a thermostat valve
- Tee 15 preferably in a twin version (alternatively two single tees can be used), is fitted in a so-called pour-in box to be embedded in the cast floor and connected to the main supply and return conduits 19 and 20 of the central heating system.
- These conduits preferably run through fixed outer casings, as a result of which the entire system is very flexible and, if necessary, allows easy fitting and replacing of the pipes.
- the connection of conduits 19 and 20 to tee 15 can be made in any desired way, for example, by means of compression fittings or, preferably, by quick release push-in fittings.
- Tee 15 is usually connected to fitting-block 1 by connecting pipes between the inlet and outlet openings 16 and 17 of the tee and the respective inlet and outlet openings 2 and 3 of the fitting-block.
- connection pipes are preferably short and more preferably openings 2 and 3 of the fitting-block are above and perpendicular to the inlet and outlet openings 16 and 17 of the tee and the connection pipes run substantially vertically.
- the connection of the pipelines to the tee and the fitting block can be made in any desired way, as described above.
- the pour-in box is preferably covered with a cover plate 18.
