    Title: Pump module for use in an underfloor heating distributor
    The present invention relates to a pump module for use in a floor heating distributor, which distributor comprises a pump, a tube for supplying fluid to at least one tube of the floor heating, and a tube for receiving fluid from at least one tube of the underfloor heating.
    Underfloor heating systems and distributors for use in such systems are known. In general, floor heating comprises at least one pipe positioned under a floor. The underfloor heating is used by transporting hot fluid through the pipe, causing the floor to radiate heat. A practical example of a fluid that can be used in underfloor heating is water.
    The distributor has various functions in the underfloor heating, including connecting the pipe to a heat source and an associated supply of fluid, and to an outlet of fluid. In many practical cases the discharge of fluid is connected to the heat source, so that there can be a continuous cycle of discharged fluid that is heated by the heat source, supplied to the tube and used for releasing heat, and again to the heat source is disposed of. Furthermore, for cases where the supply of fluid has a temperature that is actually too high for a desired operation of the floor heating, the distributor is arranged to allow a connection between the supply of fluid and the discharge of fluid, so that the fluid becomes can be used to cool the fluid that will be used to perform the heating function of the floor heating. For that reason, the distributor comprises a valve or the like, which can be opened or closed to an appropriate degree, based on a result of a measurement of a temperature of the fluid that has passed the heat source. By controlling the valve or the like, it is possible to achieve a situation in which there are practically no variations in the heat output of the floor heating, or to achieve a decrease or increase in the heat output in the event that a user of the underfloor heating changes the temperature setting.
    In the case that the floor heating comprises more than one tube, the distributor also has a function in distributing the incoming fluid over the various tubes. In that case, a controllable valve or similar means for opening and closing a pipe in accordance with a desired operation of the floor heating is provided at the inlet of each pipe.
    In many practical examples of underfloor heating, a circulation pump is used to realize fluid flows through the distributor and the at least one pipe of the underfloor heating, in a manner as desired.
    In general it can be said that the pump is arranged at a position between on the one hand the heat source and the supply of fluid to the distributor, and on the other hand the inlet of the at least one tube. In order to connect an inlet of the pump and an outlet of the pump to the appropriate components of the distributor, suitable connecting means are used, such as tube segments and connection blocks. A terminal block is a component that includes an internal space, and at least two terminal openings that provide access to the internal space from outside the terminal block, and which is used to connect at least two components to each other in such a way that it is possible to is that fluid flows from one component to another. For that reason, each of the components is connected to the positions of the connection openings on the connection block. Due to the use of the terminal block, the various components can be mounted at suitable positions without the need for alignment or direct connection.
    A problem associated with prior art distributors is that for each type of distributor and each type of pump used with the distributor, it is required to provide a specific design of the connection of the pump to the other components of the distributor to have. It is common that the various components are made of steel, and this means that specific molds must be made, which entails relatively high costs. A disadvantage of using steel is that the components must be subjected to consideration processes before they are ready for use.
    It is an object of the present invention to provide a new approach to component design for connecting a pump to other components of a distributor, which approach involves a reduction of costs over the conventional situation, while a compromise with regard to the functionality of the components is avoided. The object is achieved by means of a pump module which comprises the following: an internal space, a valve seat located in the internal space, and a number of connection openings giving access to the internal space from outside the pump module, one side of which the valve seat has at least two connection openings, one of which is intended to be connected to the pump of the distributor, and wherein there are at least three connection openings on another side of the valve seat, one of which is intended to receive a temperature meter, and of which another is intended to be connected to a sleeve of the distributor.
    The present invention provides a pump module that is suitable for use in various distributors, and which offers many possibilities. Based on the fact that the pump module has a valve seat, it is possible to use a valve arrangement in the pump module if desired. Furthermore, the pump module has various connection openings, which makes many different applications of the pump module possible. Each of the connection openings can be connected to a component of a distributor in such a way that it is possible for fluid to flow from the component to the internal space of the pump module, or vice versa. If a connection opening is not used, it can be closed by any suitable sealing means.
    The pump module according to the present invention can be manufactured in mass production, which is very favorable, since such a method of production entails relatively low production costs. In a distributor, the pump module can be mounted on an inlet side of the pump and on an outlet side of the pump. It is therefore possible for a distributor to be equipped with more than one pump module.
    If the pump module is installed on an inlet side of the pump, the following connections can be made: - a connection to the pump and a connection to a fluid supply at the distributor, on the side of the valve seat where there are at least two connection openings and which will hereinafter be referred to as pump side; and - a connection to a sleeve of the distributor that is used to receive fluid from the at least one pipe of the floor heating, a connection to a discharge of fluid from the distributor, and a connection to a temperature meter, on the side of the valve seat where there are at least three connection openings, and which will hereinafter be referred to as the tubular side.
    If the pump module is installed on an outlet side of the pump, the following connections can be made: - a connection to the pump and a connection to a fluid drain from the distributor, on the pump side; and - a connection to a sleeve of the distributor that is used to supply fluid to the at least one pipe of the floor heating, and a connection to a temperature meter, on the sleeve side.
    The pump module can be used as an end component mounted at one end of a sleeve of the manifold. In a practical embodiment of the pump module, the orientation of the connection on the sleeve is perpendicular to the orientations of the other connections, that is, the direction of a flow of fluid through the connection opening where the sleeve is connected to the pump module is perpendicular to the directions of fluid flows through the other connection openings.
    In view of the fact that two pump modules can be used in a distributor, each of the pump modules being mounted on a different side of the pump, in a mirrored configuration, it is advantageous to have two connection openings intended for a temperature meter and located at opposite positions in the pump module. In this way it is possible to have a temperature meter in each of the pump modules, the two temperature meters being arranged on the same side of the distributor, so that they can be seen from one side of the distributor. If the pump module has the said two opposite opening, then one connection opening is used to receive a temperature meter, and another connection opening is closed.
    The pump module is preferably made of a composite material, instead of the conventional steel. In general, the composite material may comprise a polymer matrix and a reinforcing material. An example of a suitable material is polyamide that contains up to 30% glass. This is an extremely hard material that can withstand temperatures from -40 ° C to 140 ° C and pressures up to 30 bar (30 * 105 Pa). The material is thus very well able to function under all possible circumstances that can prevail in floor heating. An advantage of using a composite material as mentioned is that balancing processes are not necessary during the manufacturing process of the pump module. As a result, the manufacturing process can be faster and cheaper.
    For attaching the pump module to other components of the distributor, such as a sleeve on one side and a closing plate on the other side, it is favorable for the pump module to be provided with openings for receiving threaded ends, which openings extend over extend an entire length of the pump module. At the ends of the pump module, where the pump module is to be positioned against another component, sealing means such as O-rings can be provided to ensure a fluid-tight connection.
    When the present invention is put into practice, a pump module is provided that can be used in many types of underfloor heating and distributors. Depending on the specific requirements, the pump module may or may not be used in combination with a valve construction. Furthermore, various connections can be made, such as a connection to a pump, a connection to a sleeve of a distributor, a connection to a supply of fluid to a distributor, a connection to a discharge of fluid from a distributor, and a connection to a thermometer. On the basis of an application of the pump module according to the present invention, costs can be saved compared to conventional situations in which there are tailor-made connections between the various components of a distributor.
    The present invention relates to a pump module as described in the foregoing. The present invention furthermore relates to an assembly of a pump module and a valve arrangement which is located at the level of the valve seat in the pump module. The present invention also relates to an underfloor heating distributor, comprising a pump, a tube for supplying fluid to the underfloor heating, a tube for receiving fluid from the underfloor heating, and at least one pump module, wherein a connection opening of the pump module is connected to the pump, a temperature meter being included in another connection opening, and yet another connection opening being connected to a tube of the distributor. In the distributor, yet another connection opening can be connected to a supply of fluid to the distributor or a discharge of fluid from the distributor. Another device that falls within the scope of the present invention is a floor heating system, comprising at least one pump module, in particular a distributor which is equipped with at least one pump module.
    The present invention will be further elucidated on the basis of the following description of an underfloor heating distributor and a pump module used therein, with reference to the drawing, in which like reference numerals indicate like or similar components, and in which: Figure 1 shows a front view of a floor heating distributor, which distributor is shown in a normal, functional orientation; Figure 2 shows a perspective view of a pump module that is part of the distributor as shown in Figure 1; Figure 3 shows a side view of the pump module; Figure 4 shows another side view of the pump module; Figure 5 shows a side view of a longitudinal section through the pump module; and Figure 6 shows a perspective view of an assembly of the pump module and a valve arrangement, the pump module being shown in a transparent manner.
    Figure 1 shows a distributor 1 for use in floor heating. A floor heating system is not shown as a whole in the figures, but it is known that such a system, in addition to a distributor 1, comprises at least one pipe positioned under a floor and suitable for transporting fluid. The at least one tube, which will hereinafter be referred to as heating tube, can be of any desired shape and length, it being advantageous if a given floor is covered as much as possible by the heating tube, and as pieces of the heating tube that are closest to located at the inlet of the heating pipe are interspersed with sections of the heating pipe that are closest to the outlet of the heating pipe in order to achieve an even distribution of heat over the floor. In the example shown, the distributor 1 is suitable for use in floor heating with seven heating pipes (not shown). In the following, a general description of the construction and functioning of the distributor 1 will be given, assuming that the fluid used in the underfloor heating is water.
    The distributor 1 comprises a number of components, including - a supply pipe 10 for supplying water to the distributor 1, in particular water that has passed a heat source (not shown) and has a relatively high temperature; - a pump 11 for realizing an actual displacement of water through the distributor 1 and the heating pipes; - a drain 12 for draining water from the distributor 1 if desired; - a tube 13 for supplying water to the heating pipes, which tube 13 will hereinafter be referred to as supply tube 13, and which tube 13 comprises connection openings 14 for connecting the tube 13 to the heating tubes, and controllable valves 15 for opening and closing the connection openings 14 in accordance with actual heating requirements; - a control unit 16 for controlling the operation of the valves 15 of the supply duct 13; - a tube 17 for receiving water from the heating tubes, which tube 17 will hereinafter be referred to as return tube 17, and which tube 17 comprises connection openings 18 for connecting the tube 17 to the heating tubes, and tap valves 19 for manual opening and closing the connection openings 18; - a drain pipe 20 for draining water from the distributor 1, which can lead to the heat source to ensure that the water can be reheated after it has been used in the floor heating; - two temperature meters 21, wherein one temperature meter 21 is arranged at a position for detecting the temperature of the water in the supply duct 13, and wherein another temperature meter 21 is arranged at a position for detecting the temperature of the water in the return sleeve 17; and - two pump modules 2, wherein one pump module 2 is arranged at a position for connecting the supply duct 13 to an outlet of the pump 11, and wherein another pump module 2 is arranged at a position for connecting the return duct 17 to a inlet of the pump 11.
    For the sake of clarity, in the following, the pump module 2 mounted on the outlet side of the pump 11 will be referred to as supply pump module 2a, and the pump module 2 mounted on the inlet side of the pump 11 will be referred to as return pump module 2b.
    The pump modules 2 are identical, and are preferably manufactured in mass production in order to be as cheap as possible. A suitable material for the pump modules 2 is a composite material.
    Figures 2-4 give a more detailed representation of the pump module 2. A striking feature of the pump module 2 is that it has different connection openings 22, 23, 24, 25, 26, 27. Based on that data, the pump module 2 can be used in many ways. In particular, in the example shown, one connection opening 22 of the pump module 2 is used for connection to the pump 11. Two other connection openings 23, 24 of the pump module 2, which are arranged at opposite positions of the pump module 2, are used to receive a temperature meter 21. In each of the pump modules 2a, 2b used in the distributor, one of the connection openings 23, 24 is in fact provided with a temperature meter 21, while another of the connection openings 23, 24 is closed. A relatively large connection opening 25 of the pump module 2 is used for connection to a tube 13, 17. Two other connection openings 26, 27 of the pump module 2 are used for connection to a supply or drain of water. In the supply pump module 2a, one of these connection openings 26, 27 is used for connection to the drain 12, while another of these connection openings 26, 27 is closed. In the return pump module 12b, one of these connection openings 26, 27 is used for connection to the supply pipe 10, while another of these connection openings 26, 27 is used for connection to the discharge pipe 20.
    It is advantageous if the connection openings 22, 23, 24, 25, 26, 27, with the exception of the connection opening 25 for connection to a tube 13, 17 of the distributor 1, are provided with suitable means such as internal screw thread for easy connection to other components of the distributor 1.
    An advantage of using the identical pump modules 2 in the distributor 1 is that there is no need for tailor-made connecting means. Furthermore, the pump modules 2 can still be used when the design of the distributor 1 is changed to meet new requirements, based on the fact that the pump modules 2 can have various connection openings 22, 23, 24, 25, 26, 27, in conveniently chosen positions. In addition to the connection openings 22, 23, 24, 25, 26, 27, the pump module 2 has another feature that increases its ability to be used to make various connections in various types of distributors 1. This feature is a valve seat 28 disposed in an interior space 29 of the pump module 2, as shown in Figure 5.
    In the pump module 2 the position of the valve seat 28 is chosen such that two parts of the internal space 29 can be distinguished, a first part 29a of the internal space 29 being a part where the connection opening 22 for connection to the pump 11, and the connection opening 26 for connection to a supply or drain of water are located, and wherein a second part 29b of the internal space 29 is a part where the connection openings 23, 24 for receiving a temperature meter 21, the connection opening 25 for connection on a tube 13, 17, and another connection opening 27 for connection to a supply or drain of water.
    Figure 6 illustrates how a valve arrangement 30 can be arranged in the pump module 2. For the sake of completeness, it is noted that the valve provision 30 is adapted to block a passage 31 through the valve seat 28 in one position, and to leave said passage 31 open in another position. To achieve this, the valve arrangement 30 in the example shown has support components 32 for supporting the valve arrangement 30 on the valve seat 28, and a closure component 33 for closing the passage 31, flexible connections being made between the support components 32 and the closure component 33, and wherein an operating rod 34 is provided to bring the closure component 33 into a desired position.
    The operating rod 34 of the valve arrangement 30 can be used in any suitable manner. The return pump module 2b contains the valve provision 30 for controlling the extent to which returned water is mixed with supply water. In that case, the operating rod 34 can be manipulated on the basis of an output from the temperature meters 21. Depending on the extent to which a new supply of water is to be cooled, the passage 31 becomes in the return pump module 2b, which is located between the side of the pump module 2 where water is received from the supply pipe 10 and transported to the inlet of the pump 11, and the side of the pump module 2 where water is received from the return duct 17 and transported to the discharge pipe 20 to a greater or lesser extent opened / closed.
    For the sake of completeness, it is noted that the pump module 2 does not necessarily have to be used with a valve arrangement 30. However, due to the presence of the valve seat 28 in the pump module 2, there is the possibility of doing so, thereby extending the functionality and applicability of the pump module 2.
    In the shown example of a distributor 1, the end of each pump module 2 that is opposite the end where the pump module 2 is connected to a tube 13, 17 is closed by means of a suitable closing plate 35. In order to prevent leakage of water, sealing means such as an O-ring are placed between the end of the pump module 2 and the closing plate 35. To fix the pump module 2 at a position between the closing plate 35 and the appropriate sleeve 13, 17, use can be made of threaded ends or the like (not shown), since the pump module 2 is provided with through openings 36 for receiving such connecting means .
    When the distributor 1 with the two pump modules 2 as described above is used, the water follows the path as will be described below. The water enters the distributor 1 via the return pump module 2b, in particular the side of the pump module 2b that is connected to the pump 11. The water flows through the pump 11, and flows through the supply pump module 2a to the supply tube 13. From the supply tube 13, the water flows through one or more heating tubes, and returns to the distributor 1 at the return tube 17. Eventually, the water flows from the return sleeve 17 to the return pump module 2b. Depending on the position of the valve provision 30, the water exits the distributor 1 via the connection opening 27 of the return pump module 2b which is connected to the drain pipe 20 and / or flows to the side of the return pump module 2b where the incoming water is received.
    Like conventional distributors, the distributor 1 with the two pump modules 2 as described above and shown in Figure 1 is generally U-shaped, the sleeves 13, 17 being considered the legs of the U, and the pump 11 is mounted in the base of the U. In a normal orientation as shown in Figure 1, the sleeves 13, 17 have a substantially horizontal orientation. In the shown example of the pump module 2, the connection opening 25 for connection to a tube 13, 17 allows a water flow in a direction that is substantially perpendicular to a direction in which other connection openings 22, 23, 24, 26, 27 allow water flows. This is not essential, but practical in the given embodiment, in which the orientation of the tubes 13, 17 of the distributor 1 is substantially horizontal, as mentioned, and wherein the orientation of the supply pipe 10, the drain 12, the discharge pipe 20 and a passage between the inlet and the outlet of the pump 11 is substantially vertical.
    It will be clear to a person skilled in the art that the scope of the present invention is not limited to the examples discussed above, but that various modifications and modifications thereof are possible without going beyond the scope of the invention, such as those in the appended claims has been defined.
    It is noted that underfloor heating as described can not only be used for heating purposes, but also for cooling purposes if desired. In such a case, the supply water is relatively cold, and the return water is of a higher temperature. The present invention is suitable for use in any floor heating, and in any application of floor heating, even if the cooling function of floor heating is used.
    If a valve arrangement 30 is used with the pump module 2, then depending on the requirements, the valve arrangement 30 may be of any suitable type, including a check valve required in district heating systems.
    The pump module 2 does not necessarily have continuous openings 36 for its connection to other components of a distributor 1. In the case that the pump module 2 is provided with connecting means, other possibilities can be used, including openings which are provided with wire and which do not fully extend through the pump module 2, i.e., blind screw openings.
    The present invention can be summarized as follows. A pump module 2 for use in an underfloor heating distributor 1 comprises an interior space 29, a valve seat 28 located in the interior space 29, and a number of connection openings 22, 23, 24, 25, 26, 27 which are outside the pump module 2 given access to the internal space 29. The pump module 2 can be used in combination with a valve arrangement 30 for opening / closing a passage 31 through the valve seat 28. Furthermore, various components of the distributor 1, including a pump 11, a tube 13 for supplying water to pipes of the floor heating, and a tube 17 for receiving water from said tubes, via the connection openings 22, 23, 24, 25, 26, 27 are connected to the pump module 2, at suitable positions on the pump module 2. The pump module 2 is widely applicable, and offers advantages over specially designed connections in a distributor 1, including the advantage of reduced costs.
    The functionality of the pump module 2 according to the present invention can be described as follows: - transporting water or another suitable medium, which can be hot or cold, and which can be provided with an additive such as glycol; - establishing a connection between heat source, pump 11, supply duct 13, and return duct 17; - the realization of thermal control and mixing of the medium; - the realization of flow control and mixing of the medium; and - controlling flow direction of the medium.
