Definitions

  • This invention relates to a hydraulic assembly for a combined system for room heating and for the production of domestic hot water and to a wall-mounted boiler provided with such an assembly.
  • the hydraulic layout of the boiler is basically defined by the use of only three valve devices, in combination with a secondary plate heat exchanger.
  • the three valve devices are:
  • the centrifugal pump valve device basically comprises an inlet connection located on a degassing chamber, an outlet connection located on a volute body containing the centrifugal impeller and an electric motor.
  • the delivery valve device basically comprises a double rear connection for the secondary exchanger and two connections, respectively, for the primary circuit (delivery) and the secondary circuit (domestic hot water outlet).
  • the return valve device basically comprises a double rear connection for the secondary exchanger and two connections, respectively, for the primary circuit (return) and for the secondary circuit (domestic cold water inlet).
  • the secondary plate heat exchanger for the production of domestic hot water of the conventional type, also used as a hydraulic bar comprises two separate countercurrent circuits with four terminal connections located on the same plane that define the inlet and outlet of the primary and secondary circuit, respectively. On these four connections, the delivery and return valve devices are assembled so that the secondary exchanger is arranged alternately on the front or on the back of the delivery and return valve devices.
  • the air vent valve, the three-way diverter valve, the safety valve, the connection for connecting to the expansion tank, and the connection for the pressure gauge can be integrated with the centrifugal pump valve device.
  • the three-way diverter valve, the differential bypass valve, and the pressure switch can be integrated with the delivery valve device.
  • the flow sensor for controlling the sanitary removal, the system inlet valve, and the system drain tap can be integrated with the return valve body.
  • EP1188991 discloses a hydraulic assembling according to the preamble of claim 1, EP1026456 , DE20015722U1 , EP3361182 , CN102042637 , EP3370011 , and EP3252394 .
  • the research is continuously aimed at reducing the production costs of wall-mounted boilers and reducing their size (increasingly configuring them as household appliances).
  • the purpose of this invention is, therefore, to provide a hydraulic assembly for a combined system for room heating and for the production of domestic hot water that is free from the drawbacks of the state of the art and is, in particular, easy and economical to implement.
  • Another purpose of this invention is to provide a wall-mounted boiler provided with a hydraulic assembly for a combined system for room heating and for the production of domestic hot water that is free from the drawbacks of the state of the art and is, in particular, easy and economical to implement.
  • a hydraulic assembly is provided for a combined system for room heating and for the production of domestic hot water and a wall-mounted boiler provided with a hydraulic assembly according to the attached claims.
  • the reference number 1 denotes, as a whole, a combined system for room heating and for the production of domestic hot water.
  • the system 1 comprises a wall-mounted boiler 2 and a hydraulic network 3 hydraulically connected to each other.
  • the hydraulic network 3 comprises, in turn, in a known way, a primary heating circuit 4 and a secondary circuit 5 in which domestic hot water flows.
  • the primary circuit 4 comprises a pipe 6 for delivering hot water to at least one heating element 7 (preferably provided with a zone valve arranged near and immediately upstream of the heating element 7) and a pipe 8 for returning cold water to the wall-mounted boiler 2 from the heating element 7.
  • the secondary circuit 5 is joined to at least one domestic hot water dispenser body 9 (removal tap or mixer).
  • the wall-mounted gas boiler 2 comprises:
  • the secondary heat exchanger 18 is activated when there is a demand for domestic hot water, that a user detects with a flowmeter 23 through the dispenser body 9.
  • the primary circuit 4 also comprises an outlet pipe 61 for the domestic hot water from the secondary heat exchanger 18, through which the dispenser body 9 is supplied.
  • the centrifugal pump assembly 21 comprises, in turn, an electric motor 24 that rotates an impeller 25, in turn enclosed in a pump body 26.
  • Apressure switch 39 is preferably integrated with the centrifugal pump assembly 21.
  • the pump body 26 is provided with a fitting for the pressure switch 39, and a fitting 29 to connect to the return pipe 16, and a fitting 30 to connect, through the pump interface 28, to the hydraulic return valve assembly 19.
  • the hydraulic return valve assembly 19 is intended to regulate the flow of water to/from the wall-mounted boiler 2 and comprises, in addition to a corresponding one-piece support body 31, the following devices: an expansion tank 32, a safety valve 33 for the primary circuit 4 that, if needed, is predisposed to discharge the water through a drain pipe, an air vent valve 34, a three-way valve 35 intended to activate the sanitary phase of the wall-mounted boiler 2 diverting the flow towards the secondary heat exchanger 18 and having an electric motor 36, which in turn activates a corresponding deflector shutter 37 subjected to the action of a helicoidal spring 38, and a check valve 40.
  • the hydraulic return valve assembly 19 also comprises the following devices: the domestic cold water flowmeter 23, a primary heating circuit 4 inlet valve 41, a system drain tap 42 that, if necessary, drains the water through a drain pipe 43 (through which the water drains even if the safety valve 33 is controlled).
  • the support body 31 is, therefore, provided with the following fittings:
  • Each pair of fittings 55, 56 is arranged on opposite sides of the support body 31.
  • the pair of fittings 55 is arranged at the front of the support body 31 while the other pair of fittings 56 is arranged at the back of the support body 31.
  • the hydraulic valve assembly 20 is also designed to regulate the water flows to/from the wall-mounted boiler 2 through two connections, respectively, for the primary circuit (delivery) and for the secondary circuit (domestic hot water outlet), and it comprises a corresponding one-piece support body 57.
  • the support body 57 is provided with the following fittings:
  • the pairs of fittings 62, 63 lie on different planes. In particular, the pairs of fittings 62, 63 lie on parallel planes. Each pair of fittings 62, 63 is arranged on opposite sides of the support body 57. In particular, as shown in Figures 3 to 5 , the pair of fittings 62 is arranged at the front of the support body 57 while the pair of fittings 63 is arranged at the back of the support body 31.
  • both one support body 31 and the other support body 57 can be provided with additional fittings, in addition to those listed, and possibly closed with appropriate caps 67.
  • a heating water course 64 is defined in the domestic water phase
  • a domestic water course 65 is defined when its removal from the dispensing element 9 is activated in countercurrent in relation to the course 64.
  • the heat exchanger 18 is, therefore, provided with four connections 66, of which, respectively, a pair of connections 66A, 66B for the inlet and outlet of the course 64 and a pair of connections 66C, 66D for the inlet and outlet of the course 65 (clearly the connections 66A, 66D for the inlet course 64 and the outlet course 65 are aligned at the same and first end of the heat exchanger 18 while the connections 66B, 66C for the inlet course 65 and the outlet course 64 are aligned at the same and a second end of the heat exchanger 18).
  • the connections 66 lie on the same plane. In other words, the connections 66 are made at the same face of the box body that defines the secondary heat exchanger 18.
  • the pairs of fittings 55, 56 are intended to selectively make the hydraulic connection with a first pair of connections 66 and, similarly, the pairs of fittings 62, 63 are intended to selectively make the hydraulic connection with a second pair of connections 66 depending on the front/rear position of the secondary heat exchanger 18 with respect to the hydraulic return and delivery valve assemblies 19, 20.
  • the secondary heat exchanger 18 is connected to pairs of fittings 55 and 62 in such a way that it is arranged in front of the support bodies 31 and 57.
  • the pairs of fittings 55 and 62 are arranged, in use, on a common plane to connect with the connections 66.
  • the secondary heat exchanger 18 is connected to the pairs of fittings 56 and 63 so that it is arranged at the rear of the support bodies 31 and 57.
  • the pairs of fittings 56 and 63 are arranged, in use, on a common plane to connect with the connections 66.
  • this second embodiment presents, overall, a reduced overall size compared to the first embodiment since the secondary heat exchanger 18 is basically arranged side-by-side with the centrifugal pump assembly 21.
  • two secondary heat exchangers 18*, 18** are provided; the secondary heat exchanger 18* is connected, respectively, to the pairs of fittings 56 and 63 so as to be arranged at the rear with respect to the support bodies 31 and 57, while the other secondary heat exchanger 18** is connected, respectively, to the pairs of fittings 55 and 62 so as to be arranged at the front with respect to the support bodies 31 and 57.
  • the hydraulic return and delivery valve assemblies 19, 20 are, in fact, prepared to connect with the secondary heat exchanger 18 in two different positions, opposite each other; the position (front and/or rear) of the secondary heat exchanger 18 with respect to the hydraulic return and delivery valve assemblies 19, 20 is chosen according to the space requirements and without needing to change the position of the other devices (in particular, the flowmeter 23 is provided with a double outlet connection and is designed to convey domestic water to the secondary heat exchanger 18 positioned either on the front or back of the valve body).
  • the deflector shutter 37 of the three-way valve 35 is controlled by the electric motor 36 and is subjected to the action of the helical spring 38 to alternatively close one way, corresponding to the fitting 53 with the primary heating circuit 4 for the domestic hot water production phase, or one way for room heating, leaving open, in any case, a hydraulic communication way with a centrifugal pump assembly 21 suction pipe.
  • the deflector shutter 37 has a differentiated section on the two closing diameters in order to reduce the pressure drop towards the main way for the room heating phase.
  • the main advantage of the assembly made up of the hydraulic return and delivery valve assemblies 19, 20 and by the secondary heat exchanger 18 consists in preparing the rational arrangement of the secondary heat exchanger 18 on the front or alternatively on the back of both the hydraulic return valve assembly 19 and the hydraulic delivery valve assembly 20. All this translates into a significant reduction in investment costs in moulds and equipment, as well as in a significant reduction in the overall size and a consequent reduction in production costs.
