Definitions

  • This invention relates to an innovative boiler unit (termed also 'manifold') for use in gas boilers with dual function of environment heating and sanitary water heating.
  • the prior art has proposed supplying a certain grouping of the various devices so as to supply basically two monobloc bodies arranged at the two ends of the secondary exchanger.
  • This arrangement is very constraining as regards the physical sizing of the parts, the distance between the units being in practice linked to the size of the secondary exchanger.
  • various connections remain to be made between the two parts and the chances of hydraulic losses are not reduced.
  • the general purpose of this invention is to remedy the above mentioned shortcomings and other problems by making available a boiler and an innovative boiler unit bringing together in a single body the various union connections to members of the boiler and including a secondary exchanger with reduced space occupied.
  • a boiler unit for connections inside of gas boilers with primary exchanger and functions of sanitary water and radiator heating system fluid heating characterized in that it includes joined in a single body a first and a second series of unions with the first series including a union for connection to the delivery of the heating system and a union for connection to the return from the heating system and a union for sanitary water inlet and a union for outlet towards heated sanitary water users with the second series including a union toward the primary exchanger and a union for arrival from the primary exchanger with their projecting from the body a secondary exchanger for sanitary water heating with said secondary exchanger having inlets and outlets connected to other unions on said body and with the body realizing within it appropriate connections between the unions of the first and second series and with the other unions for connection with the secondary exchanger and with there being inside the body in addition a valve unit for controlled connections between unions of the first series, the second series and the other unions.
  • FIG 1 shows a boiler unit designated as a whole by reference number 10 for use in boilers for environmental and sanitary water heating.
  • the unit 10 includes a single functional and connection body 11 from which a secondary exchanger member 12 projects in feathered position and in particular like plates.
  • the unit is based on a single main body molded in brass and machined. This ensures extremely high overall rigidity accompanied by a very compact overall size.
  • the body extends longitudinally advantageously in the same direction of extension as the secondary exchanger 12.
  • a first series of aligned unions includes the union 13 for water delivery to the radiators, the union 14 for return of the water to the radiators, the union 15 for outlet of the sanitary hot water, and the union 16 for inlet of the sanitary water from the mains.
  • the second series includes a union 17 virtually aligned axially with the union 13 and connected thereto for inlet of water arriving from the primary exchanger of the boiler and a union 18 for sending of the water to the primary exchanger.
  • a connection 19 for a temperature measurement probe of the sanitary hot water axially aligned with the opposite union 15 of outlet of the sanitary hot water.
  • a motor reducer 20 for operation of a 3-way valve inside the body projects from the body 11 as clarified below.
  • a union 21 for filling the boiler can be provided above the sanitary water inlet union 16. At one end across the unions 13 and 17 there can also be provided a union 22 for connection of a known safety valve in communication with the unions 13 and 17 in case of overpressure in the heating circuit.
  • the secondary exchanger 12 has its primary branch with inlet 23 connected through a union duct 24 made in the body 11 to the internal passage between the unions 13 and 17 of the heating circuit to receive the heating water therefrom.
  • the outlet 25 of the primary branch is in turn connected through an underlying rigid tube 26 to an inlet 27 arranged beneath the body 11 to feed the water back into the circuit of the primary exchanger through the 3-way valve described below.
  • the secondary exchanger 12 has the inlet 28 for mains water to be heated connected to a union 29 that is beneath and transversal to the union 16 to flow into it as shown in FIG 5). To bring the inlet 28 back near the body 11 the connection between the inlet 28 and the union 29 is advantageously obtained by means of a deep-drawn member 30 placed as a seal on the upper external wall of the exchanger.
  • the exchanger then has a heated water outlet that connects to a union 31 below and transversal to the union 15 to flow there into.
  • unions 23, 29, 31 are connected and sealed to the corresponding passages in the exchanger thanks to the resting of the exchanger against them with interposition of appropriate gaskets (not shown). Screws 32 hold the exchanger in position against the unions and compress the seals.
  • FIG 4 shows the 3-way valve with its passages and connections.
  • the union 14 for return of the water from the radiator circuit extends in a straight line inside the body 11 until reaching a first inlet 34 of the 3-way valve 33.
  • the valve has a second inlet 35 facing opposed to the inlet 34 and connected directly the underlying inlet union 27 for inlet of water outlet from the primary branch of the secondary exchanger.
  • the 3-way valve has a chamber 36 between the two inlets 34 and 35 that is connected directly to the outlet union 18.
  • the movement can be continuous to realize a proportionate and not merely on-off valve.
  • FIG 5 shows the passage of the sanitary water from the mains inlet 16 to the inlet 29 in the secondary exchanger.
  • tubular pocket filter 39 of metal mesh inserted in the duct that is an extension of the union 16 toward the interior of the body of the unit so as to withhold any impurities from the mains.
  • a flow sensor 40 along the duct.
  • Said sensor is realized by means of an impeller 41 made to move by the flow traversing the duct.
  • a magnetic sensor (reed) 42 detects the rotation of the impeller from the outside and produces impulses signalling the existence of the sanitary water flow.
  • the signalling will be proportionate to the sanitary water requirement and as clarified below can serve to control the proportional valve 33 to shunt a larger quantity of water from the heating circuit to the secondary exchanger accordingly.
  • the unit 10 includes a cylindrical pierced-wall filter 45 inserted with its axis parallel to the passage 54 between the unions 13 and 17 (as may be seen in FIG 6) so as to not obstruct the flow between them but at the same time filter the heating circuit water directed to the duct 24 and towards the secondary exchanger. Thanks to the axial flow secured when the radiator heating circuit is active, the filter undergoes an effective cleaning function.
  • FIG 7 shows diagrammatically a boiler with the above-mentioned unit. Said figure clearly shows the connections of the unit 10 to the heating circuit (with the burner 47, the primary exchanger 48 and the circulation pump 49 on one side and the radiator system 50 on the other) and to the sanitary water circuit (with the inlet 51 from the mains and the outlet to the users 52).
  • the boiler will also include a know control circuit 53 controlling the circulation pump, lighting of the burner and the 3-way valve depending on the signals of different sensors as basically known for this type of boiler.
  • the control system commands the valve 33 to shunt all or part of the heating circuit flow to the secondary exchanger so as to heat the sanitary water required. If the burner is extinguished, the control device 53 will relight it.
  • the control system can naturally be connected to a thermostat or a chrono-thermostat 55 to control the environmental heating. There can then be all the sensors that usually are present in boilers such as for example flame detectors, sensors of the temperature of the fluids circulating in the system, for example inlet to and/or outlet from the primary exchanger, and various block detectors et cetera.
  • boilers such as for example flame detectors, sensors of the temperature of the fluids circulating in the system, for example inlet to and/or outlet from the primary exchanger, and various block detectors et cetera.
  • the plate-type heat exchanger with its flag arrangement allows very easy maintenance thereof and of the entire unit. In addition, being thus constructed, it can undergo without difficulty even large increases in volume.
  • the unit is made advantageously of a single molded and machined brass body to guarantee extremely high rigidity of the assembly accompanied by a very compact overall size and bringing together the components this way.
  • the height dimension is very limited and allows reducing the height occupied by the boiler.
