Definitions

  • the present invention relates to residential mixed systems adapted to supply both heating and sanitary water, i.e. systems in which the hot water from one or different supplies is used both for heating dwellings through radiator elements (heaters) and for producing sanitary warm water for several uses.
  • the primary hot water can be supplied either by a local gas burner, or by a centralized plant or by a station of a district heating system.
  • a hydraulic group of this kind comprises a delivery subgroup and a return subgroup connected to a water/water heat exchanger of the type comprising a plurality of plates brazed together.
  • Fig. 1 of the above mentioned patent illustrates a hydraulic diagram of a group to which the present invention could be applied.
  • the delivery subgroup is formed as a metal block, typically of brass, housing a three-way valve, a connection to the main heat exchanger, a connection to the radiator system, an outlet connection for the sanitary water, two connections to the water/water heat exchanger, as well as seats or recesses for a pressure switch and a bypass valve with associated outlet connections.
  • the return subgroup is formed as a metal block, typically of brass, housing a water flow detector that actuates the three-way valve (in the above mentioned patent a pressure drop device, and more recently a flow transducer or meter), a connection to the radiator system, an inlet connection to the sanitary water, an outlet connection to the pump, and the other two connections to the water/water heat exchanger.
  • the pump can be embedded in the second subgroup made of plastic material or anyhow secured to the second metal subgroup.
  • any constructional improvement affecting only a part of the group might result in being incompatible with the remainder of the group, to the point of requiring the replacement of the whole group.
  • the invention further relates to a hydraulic group for a system providing for both heating and sanitary water and equipped with a return subgroup of the above mentioned type.
  • unit IIA is made of brass and is preferably a "light weight" unit, i.e. formed with a small amount of metal material
  • unit or portion IIB is made of a composite material based on polyammide, i.e. comprising a polymeric base material and at least one filler.
  • a preferred material is for instance the one known as PA 6.6 GF30s comprising Polyammyde PA 6.6 filled with a 30% of glass fibers (Glass Fibers GF30).
  • Unit or portion IIB is more massive and is formed inside the pump body, or in other words the pump body PC is formed in such way as to incorporate the other group functions such as the three-way valve, the drain tap, the connection to the safety valve, etc. that will be illustrated later on.
  • the metal material from which unit IIA is formed is preferably brass (UNI EN 12165 CW617N).
  • the brass subgroup IIA is formed as a cylindrical body 11 housing a flow detector 12 of the sanitary water and providing at the opposite end for a connection 13 to the circuit of the sanitary water.
  • the flow detector 12 can be either a transducer supplying an output electric signal representative of the flow/no-flow condition, or a device metering the water flow.
  • transverse portions 16 and 18 for connecting the water-water heat exchanger to the subgroup, and a tilted portion 19 housing the tap 20 for filling the primary circuit, and also a connection 21 for the connection of the subgroup to unit IIB.
  • Portion IIB is substantially made up by the pump body PC and incorporates a three-way routing valve 22 (integrated in the pump body PC), and in accordance with an advantageous embodiment of the invention, this valve extends vertically.
  • a drain tap 24 for emptying the plant, a connection 25 (if required) to an external bypass pipe, a connection 26 to a safety valve and a connection 27 for connecting the portion IIB to the above illustrated brass group IIA.
  • the advantage of a vertical construction of the routing three-way valve 22 is that of enabling the construction of the inner functional parts of the routing three-way valve as a single component assembled so as to be completely removable (like a sort of "cartridge"). This way the worn parts can be replaced without disassembling the pump or other parts of the plant, and moreover the standard connections are maintained for the actual linear actuators.
  • the group according to the invention accomplishes the return subgroup functions partly in the light-weight brass portion or unit IIA (transducer and filling), and partly in the pump body, thus providing for a consistent reduction of the metal material (brass) while nevertheless maintaining all the functional features of a traditional return group.
  • the metal (brass) is present in all those parts mostly subjected to water hammers (particularly in the sanitary circuit) where traditionally the composite materials (plastics) would not assure an absolute reliability. Also in this case the distance between the axes of the sanitary and primary return connections 13 and 23 is maintained (65 mms).
  • the hydraulic circuit according to the invention is completely interchangeable with the existing ones and allows their advantageous replacement without modifying the parts made of metal plates of the existing boilers.
