Definitions

  • the present patent is related to heat regulating units or HIU type units ("Heat Interface Unit”), and in particular concerns a new heat regulating unit with at least one compact multi-circuit exchanger.
  • HIU Heat Interface Unit
  • Heat regulating units are interface units normally installed in large complexes where there are numerous separate users or residential units.
  • Each user instead of being served by its own dedicated boiler, is connected to a central boiler, or central heating plant, which supplies thermal energy to the entire complex both for heating and for the production of domestic hot water.
  • An interface unit connects the central heating plant with the domestic hot water and heating systems of each user. Therefore, it is not necessary to equip each user with its own energy source, rather, on the contrary, a single supply between the heating plant and each user is sufficient.
  • the interface units generally comprise a plate exchanger to transfer energy from a primary system fluid, which for example is sent and used in the building heating system, and a secondary fluid, normally used in the domestic hot water supply system.
  • the domestic hot water is therefore produced in an indirect way and sent to the users instantly, upon request, without requiring any storage of hot water.
  • Interface units are known where the water for heating is also produced indirectly by a specially dedicated plate heat exchanger, with the advantage of completely separating each user's system from the central system.
  • interface units comprising two separate exchangers, comprising a first exchanger, for the exchange between the primary fluid of the system and the fluid to be sent to the heating, and a second exchanger physically separate and independent of the first, for the exchange between the same primary fluid of the system and the water to be sent to the domestic hot water system.
  • the primary fluid coming from the thermal power plant enters said unit and, through dedicated valves, is normally sent to the first exchanger for heating, while, at the request of the user, it is totally or partially diverted towards the second exchanger for the production of domestic hot water.
  • an electronic controller manages the valves and/or other process fluid regulation devices.
  • Prior art includes plate heat exchangers comprising at least two separate circuits respectively for the circulation of a primary fluid and a secondary fluid, where said circuits are defined by a plurality of exchange plates with facing surfaces, featuring ridges and grooves, generally distributed in a herringbone pattern.
  • the object of the present patent is a new heat regulating unit, with at least one multicircuit compact exchanger.
  • the main object of the present invention is to simplify the components with respect to known units in the prior art.
  • the new control unit requires the use of a smaller number of pipes connecting the exchanger with respect to the currently known systems.
  • the new control unit requires a single regulation of the primary fluid entering the exchanger, thus reducing the number of regulating valves normally present in a HIU unit.
  • the new control unit simplifies the installation procedures, the systems, the thermoregulation and operating procedures in general, and the maintenance and repair operations.
  • the new control unit also has a compact shape thanks to the special exchanger installed that integrates the function of at least two exchangers in a single body, one for the heating system and one for the domestic hot water system.
  • Still another object of the present invention is to reduce to a minimum the waiting times for the supply of domestic hot water.
  • Another object of the present invention is to be structured according to the installation requirements, given that the exchanger can be sized and shaped according to the installation position in the control unit, overall dimensions, performance characteristics required, and so on.
  • One advantage of the present invention is to install a single exchanger that it is able to be sized according to the plant requirements, for example in a symmetrical way, that is, where the exchange surface to heat the heating fluid is substantially equal to the exchange surface to heat the domestic hot water system fluid, or asymmetrically.
  • the exchanger can also be structured in such a way that the exchange surface between the primary fluid and the heating fluid is different from the exchange surface between the primary fluid and the domestic hot water system fluid.
  • the two distinct areas of the heat exchanger designated for the heat exchange between the primary system fluid and each of the fluids of the heating and domestic hot water systems may have specific and predetermined performance characteristics, with regard to thermal yield, hydraulic resistance, or pressure loss.
  • the exchanger plates may also be specially shaped so that the primary fluid circuit has different characteristics than the two secondary fluid circuits of the systems.
  • One advantage of the present invention is that it maximizes energy efficiency.
  • the new heat regulating unit with at least one multi-circuit compact exchanger.
  • the new heat regulating unit includes:
  • a first circuit of a primary fluid suited to yield heat, which circulates between alternating pairs of the facing plates of the entire plate pack of the exchanger
  • a second circuit of a first secondary fluid suited to receive heat from the primary fluid, wherein the second circuit is limited to a first area of the plate pack
  • a third circuit of a second secondary fluid suited to receive heat from the primary fluid, wherein the third circuit is limited to a second area of the plate pack different from the first area, the first, second and third circuits being hydraulically isolated from each other;
  • At least one connector for the introduction of said primary fluid into the first circuit of the exchanger, where said inlet connector is mounted on the exchanger and is suited to be connected to a heat source from which the primary fluid originates;
  • At least one outlet connector for said primary fluid from said first exchanger circuit where said outlet connector is mounted on said exchanger and is suited to be connected to the heat source where said primary fluid returns; at least one return connector, for the introduction of said first secondary fluid into said second exchanger circuit, where said return connector is mounted on said exchanger and is suited to be connected to a domestic hot water system, from which said first secondary fluid originates; said first secondary fluid is therefore water suitable for domestic use;
  • At least one delivery connector for the outlet of said first secondary fluid from said second exchanger circuit, where said delivery connector is mounted on the exchanger and is suited to be connected to said domestic hot water system where said first secondary fluid is conveyed;
  • At least one return connector for the introduction of said second secondary fluid in said third circuit of the exchanger, where said return connector is mounted on the exchanger and is suited to be connected to a heating system, from which said second secondary fluid originates;
  • At least one delivery connector for the outlet of said second secondary fluid from said third exchanger circuit, where said delivery connector is mounted on said exchanger and is suited to be connected to said heating system where said second secondary fluid is conveyed.
  • the new heat regulating unit also includes a first regulation valve installed on the at least one outlet connector and/or on the at least one inlet connector of the primary fluid, to control the primary fluid's circulation in said first circuit.
  • the new heat regulating unit also includes further devices, described and claimed herein, suited to regulate the flow of the secondary fluids.
  • the domestic hot water circulates by effect of the upstream pressure, as a consequence of the demand by the users.
  • said second circuit may comprise a flow switch to signal circulation.
  • Said third circuit preferably comprises at least one circulation pump, for example of the on-off or modulating type.
  • said third circuit may also optionally include a second control valve, for example installed on said at least one delivery connector or on said at least one return connector of said second secondary fluid, and where said valve is normally open, to supply the heating system.
  • Said circulation pump and/or said second valve may prevent the circulation in said third circuit when there is a demand for domestic hot water.
  • the new heat regulating unit also comprises at least one control unit for said at least one control valve of the primary circuit and of said devices to regulate the circulation of fluids, which independently manages said at least one valve and said devices according to the demands.
  • the new heat regulating unit further comprises one or more sensors or probes to determine and acquire the parameters of the fluids, for example to determine the temperature of the secondary fluids leaving the exchanger, and wherein the temperature values are sent to the heat regulating unit, which then regulates the circulation of the fluids according to the demands.
  • the second and third circuit of the exchanger can be arranged side by side or adjacent to each other, where the plates for the circulation of the fluids are in turn divided into two adjacent areas, one destined for the circulation of said first secondary fluid, where the exchange with said primary fluid occurs, and one destined for the circulation of said second secondary fluid, where the exchange with said primary fluid takes place, and where the areas are in any case hydraulically isolated from each other.
  • said second and third circuit can be arranged on top of each other in the exchanger assembly, that is so that in a first area of said plate pack the exchange between said primary fluid and said first secondary fluid occurs, while in a the second area of said plate pack the exchange between said primary fluid and said second secondary fluid takes place.
  • Said second embodiment is ideally obtainable from the first configuration by rotating said second area by 180° and superimposing it on said first area, thus obtaining a different geometry with the same functionality.
  • This configuration is especially obtainable with plates of the known type.
  • the new exchanger unit therefore enables the use of a single primary exchange fluid to disperse heat, inside a compact exchanger body, to two separate secondary fluids, wherein no heat exchange takes place between said first and second secondary fluids.
  • the circuits may be arranged so that the thermal exchange, for example in countercurrent, takes place first between said primary fluid and said first secondary fluid, for example intended to then be sent/used in a domestic hot water system, then the heat exchange, for example in countercurrent, between said first primary fluid and said second secondary fluid, for example destined to then be sent/used in a heating system.
  • FIG. 1 shows the new heat regulating unit (100), where the structure of the exchanger (1) and the circuits (11, 12, 13) are only outlined and better represented in the following figures.
