Definitions

  • the present invention relates to a pump module for use in a manifold for a floor heating system, which manifold has a pump, a duct for supplying fluid to at least one pipe of the floor heating system, and a duct for receiving fluid from the at least one pipe of the floor heating system.
  • a floor heating system comprises at least one pipe which is positioned under a floor.
  • the floor heating system is operated by transporting hot fluid through the pipe, as a result of which the floor is made to radiate heat.
  • a practical example of a fluid which can be used in the floor heating system is water.
  • the manifold has various functions, including connecting the pipe to a heat source and an associated supply of fluid, and to a discharge of fluid.
  • the discharge of fluid connects to the heat source, so that there can be a continuous cycle of discharged fluid being heated by the heat source, being supplied to the pipe and being used for supplying heat, and being discharged towards the heat source again.
  • the manifold is adapted to allow for communication of the supply of fluid with the discharge of fluid, so that the fluid which is discharged can be used for cooling down the fluid which is about to be used for performing the heating function of the floor heating system.
  • the manifold comprises a valve or the like, which can be opened to a suitable extent, or closed, on the basis of an outcome of a measurement of a temperature of the fluid which has passed the heat source.
  • a valve or the like By controlling the valve or the like, it is possible to achieve a situation in which there are practically no variations in the heating performance of the floor heating system, or to achieve a decrease or increase of the heating performance in case a user of the floor heating system changes temperature settings.
  • the manifold also has a function in distributing the incoming fluid over the various pipes.
  • a controllable valve or similar means for opening or closing a pipe in accordance with a desired operation of the floor heating system is arranged at the entrance of each pipe.
  • a circulation pump is used for realizing flows of fluid through the manifold and the at least one pipe of the floor heating system as desired.
  • the pump is arranged at a position between the heat source and the supply of fluid to the manifold on one side, and the entrance of the at least one pipe on another side.
  • suitable connecting means are applied, such as duct segments and connecting blocks.
  • a connecting block is a component which comprises an internal space and at least two connection openings allowing for access to the internal space from outside of the connecting block, and which is used for interconnecting at least two components in such a way that fluid is allowed to flow from one component to another.
  • each of the components is connected to the connecting block, at the positions of the connection openings. Due to the use of the connecting block, the various components can be arranged at suitable positions without a need of alignment or direct connection.
  • a problem associated with manifolds according to the state of the art is that for each type of manifold and each type of pump applied with the manifold, a specific design of the connection of the pump to the other components of the manifold is required.
  • the various components are made in steel, and this means that specific moulds need to be made, which involves relatively high costs.
  • a disadvantage of the use of steel is that the components need to be subjected to finishing processes before they are ready for application.
  • a pump module comprising an internal space, a valve seat which is located in the internal space, and a number of connection openings which provide access to the internal space from outside of the pump module, wherein at least two connection openings are located at one side of the valve seat, one of which is destined to be connected to the pump of the manifold, and wherein at least three connection openings are located at another side of the valve seat, one of which is destined to receive a temperature gauge, and another of which is destined to be connected to a duct of the manifold.
  • the present invention provides for a pump module which is suitable to be used in various manifolds, and which offers many possibilities. On the basis of the fact that the pump module has a valve seat, it is possible to apply a valve element in the pump module if so desired. Furthermore, the pump module has various connection openings, which allows for many different applications of the pump module. Each of the connection openings may be connected to a component of a manifold, in such a way that fluid is allowed to flow from the component to the internal space of the pump module, or the other way around. 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 made in mass production, which is very advantageous, as relatively low production costs are involved with such way of producing.
  • the pump module can be arranged at an inflow side of the pump and at an outflow side of the pump.
  • a manifold may be equipped with more than one pump module.
  • the pump module may be used as an end component which is arranged at one end of a duct of the manifold.
  • the orientation of the connection to the duct is perpendicular to the orientations of the other connections, i.e. the direction of a flow of fluid through the connection opening where the duct is connected to the pump module is perpendicular to the directions of flows of fluid through the other connection openings.
  • two pump modules may be used in a manifold, wherein each of the pump modules is arranged at another side of the pump, in a mirrored configuration, it is advantageous to have two connection openings which are destined to receive a temperature gauge, and which are located at opposite positions in the pump module. In that way, it is possible to have a temperature gauge in each of the pump modules, wherein the two temperature gauges are arranged at the same side of the manifold, so that they can be seen from one side of the manifold. If the pump module has the two opposite connection openings as mentioned, one connection opening is used for receiving a temperature gauge, and another connection opening is closed.
  • the pump module is made of a composite material instead of the conventional steel.
  • the composite material may comprise a polymer matrix and a reinforcement material.
  • a suitable material is polyamide containing glass to an extent of 30%. This is an extremely hard material, which can withstand temperatures ranging from -40°C to 140°C, and pressures up to 30 bar (30 * 10 5 Pa).
  • the material is very well capable of functioning under all possible conditions prevailing in a floor heating system.
  • An advantage of using a composite material as mentioned is that finishing processes are not needed during the manufacturing process of the pump module. As a result, the manufacturing process can be faster and cheaper.
  • the pump module For the purpose of attaching the pump module to other components of the manifold, such as a duct on the one side and a closing plate on the other side, it is advantageous for the pump module to be provided with openings for receiving studs, which openings are extending along an entire length of the pump module.
  • sealing means such as O-rings may be provided at the ends of the pump module where the pump module is to be positioned against another component in order to guarantee a fluid-tight connection.
  • a pump module which is applicable in many types of floor heating systems and manifolds.
  • the pump module may be used in combination with a valve construction, or not.
  • various connections can be made, such as a connection to a pump, a connection to a duct of a manifold, a connection to a supply of fluid to a manifold, a connection to a discharge of fluid from a manifold, and a connection to a temperature gauge.
  • costs can be saved with respect to conventional situations in which custom-made connections between the various components of a manifold are present.
  • the present invention relates to a pump module as described in the foregoing. Furthermore, the present invention relates to an assembly of the pump module and a valve element which is located in the pump module at the position of the valve seat. Also, the present invention relates to a manifold for a floor heating system, comprising a pump, a duct for supplying fluid to the floor heating system, a duct for receiving fluid from the floor heating system, and at least one pump module, wherein one connection opening of the pump module is connected to the pump, wherein a temperature gauge is received in another connection opening, and wherein yet another connection opening is connected to a duct of the manifold.
  • connection opening may be connected to a supply of fluid to the manifold or a discharge of fluid from the manifold.
  • a floor heating system comprising at least one pump module, particularly a manifold which is equipped with at least one pump module.
  • Figure 1 shows a manifold 1 for use in a floor heating system.
  • a floor heating system is not shown as a whole in the figures, but it is well-known that besides a manifold 1, such a system comprises at least one pipe which is positioned under a flour, and which is suitable for transporting fluid.
  • the at least one pipe which will hereinafter be referred to as heating pipe, can have any desired shape and length, wherein it is advantageous if as much as possible of a given floor is covered by the heating pipe, and if lengths of the heating pipe closest to the entrance of the heating pipe are alternated with lengths of the heating pipe closest to the exit of the heating pipe, in order to realize an even distribution of heat over the floor.
  • the manifold 1 is suitable to be used in a floor heating system having seven heating pipes (not shown).
  • a general description of the construction and the functioning of the manifold 1 will be given, wherein it is assumed that the fluid which is used in the floor heating system is water.
  • the manifold 1 comprises a number of components, including
  • the pump module 2 which is arranged at the outlet side of the pump 11 will be referred to as supply pump module 2a, and the pump module 2 which is arranged at 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 of the pump modules 2 is a composite material.
  • FIGS 2-4 show a pump module 2 in more detail.

  • connection openings 26, 27 of the pump module 2 are used for connection to a supply or a discharge of water.
  • one of these connection openings 26, 27 is used for connection to the drain 12, whereas another of these connection openings 26, 27 is closed.
  • the return pump module 2b one of these connection openings 26, 27 is used for connection to the supply pipe 10, whereas another of these connection openings 26, 27 is used for connection to the discharge pipe 20.
  • connection openings 22, 23, 24, 25, 26, 27, with the exception of the connection opening 25 for the connection to a duct 13, 17 of the manifold 1, are provided with suitable means such as internal screw thread to allow for easy connection to other components of the manifold 1.
  • An advantage of using the identical pump modules 2 in the manifold 1 is that there is no need for custom-made connecting means. Furthermore, when the design of the manifold 1 is changed in order to meet new requirements, the pump modules 2 may still be used, on the basis of the fact that the pump modules 2 have various connection openings 22, 23, 24, 25, 26, 27 at well-chosen positions. Besides the connection openings 22, 23, 24, 25, 26, 27, a pump module 2 has another feature which enhances its capacity of being used for establishing various connections in various types of manifolds 1. This feature is a valve seat 28 which is arranged in an internal space 29 of the pump module 2, as shown in figure 5 .

  • the actuation rod 34 of the valve element 30 can be operated in any suitable manner.
  • the valve element 30 is present for controlling the extent to which return water is mixed with supply water.
  • the actuation rod 34 can be manipulated on the basis of an output of the temperature gauges 21.
