Definitions
- the present invention relates in general to the field of refrigeration systems and of air conditioning apparatuses. More particularly, the invention relates to a vertical discharge air condenser for such systems and apparatuses.
- Refrigeration and air conditioning systems use refrigerant circuits based on the circulation of a fluid between an evaporator and a condenser connected by special pipes, in which the fluid exiting from the evaporator is fed towards the condenser by means of a compressor and the fluid coming out from the condenser recirculates towards the evaporator passing through a rolling valve.
- the condenser In a refrigeration and conditioning system the condenser is typically a unit located outside the room to be cooled, which exploits the air of the surrounding environment as a means for cooling the gas circulating in the refrigeration circuit.
- the air flow through the condenser depends on the configuration of its structure. For example, capacitors are known in which the air flow is substantially horizontal, i.e. parallel to the ground or to a support plane, and condensers in which the air flow is axial or vertical, i.e. perpendicular to the ground or to a support plane.
- capacitors are known in which the air flow is substantially horizontal, i.e. parallel to the ground or to a support plane
- condensers in which the air flow is axial or vertical, i.e. perpendicular to the ground or to a support plane.
- several air condensers can be placed side by side and connected to each other.
- An axial or vertical flow condenser typically comprises a cylindrical or polygonal heat exchanger with finned walls, which rests on a base and is surmounted by a suction device provided with a motorized fan.
- the suction device creates in the heat exchanger a depression such as to axially suck a flow of air which enters transversely or radially through its finned walls. The air removes heat by convection from the finned walls of the heat exchanger, cooling the gas flowing in the refrigerant circuit housed therein and allowing condensation.
- US patent US 8627670 describes an example of a vertical discharge air condenser of this type, in which the walls of the heat exchanger comprise bundles of coplanar micro channels crossed by a refrigerating fluid.
- the bundles of micro ducts connected at their ends by inlet/outlet conduits that act as uprights, are arranged parallel in the vertical direction and have spaced fins through which the air is sucked.
- the use of micro conduits allows to obtain a large heat exchange surface whilst limiting the overall weight and the overall size of the heat exchanger and therefore of the condenser.
- Heat exchangers that employ micro conduits are typically constructed using panels consisting of a pair of conduits for feeding a refrigerant gas between which bundles of micro conduits alternated with fins transversely extend, which are suitably curved or bent to realize the perimeter walls of a chamber with a generally cylindrical or polygonal shape.
- the panels may be not only arranged adjacent to each other in a circumferential or perimetral direction, but also vertically overlapped, creating a tower structure surmounted by the suction device, whose height depends on the number of overlapping panels as well as on their respective heights.
- the power of the suction device must be chosen according to the height of the heat exchanger itself. It is known that, for allowing the passage of an air flow transversely through the walls of the heat exchanger throughout its whole height, it is necessary to generate a depression level such to compensate for the pressure drop distributed in the vertical direction of the same heat exchanger.
- the maximum height of the condenser is therefore limited by the airflow that may be sucked by the motorized fan of the suction device provided for it.
- An increase of the rotation speed of the motorized fan in order to increase the flow rate of the air flow that may be sucked involves a greater noise level of the condenser as a whole, i.e. of the heat exchanger and of the suction device mounted thereon, which is not acceptable or generally allowed by present regulations.
- the present regulations also limit the maximum power of electric motors that can be used in suction devices.
- the presence of the panels along the walls of the heat exchanger undesirably increases the noise of the air condenser as a whole.
- the technical problem posed and solved by the present invention is therefore that of supplying a vertical discharge air condenser that allows to overcome the aforementioned drawbacks with reference to the prior art.
- the configuration of the distributor element and the arrangement of the openings passing in the vertical direction is such to equalize the flow rate from the base to the top of the heat exchanger, minimizing concentrated pressure drops.
- flow regulators may be associated, for example with lamellae. This offers the advantage of allowing variations and fine adjustments of the air passage areas in order to optimize flow along the walls of the heat exchanger.
- Figure 1 is a perspective view showing a set comprising two air condensers according to the present invention
- Figure 2 is a partially sectional perspective view of an air condenser of the set of Figure 1 ;
- Figure 3 is a top plan view of the air condenser of Figure 2;
- Figure 4 shows a longitudinal section of the air condenser of Figure 3;
- Figure 5 schematically shows openings for the passage of air flow aspirated through a distributor element inserted in the heat exchanger of the condenser according to the present invention.
- a vertical discharge air condenser is generally indicated by the reference number 100 and is shown in a three-dimensional reference system in which a X direction and a Y direction, which are perpendicular to each other, define a parallel horizontal plane to the ground, and a Z direction, perpendicular to the X direction and to the Y direction, represents a vertical direction along which gravity acts.
- Figure 1 shows in particular a set comprising two air condensers 100 arranged side by side and arranged on a frame 200 comprising a base 210 and a plurality of uprights 220 which extend in the vertical direction Z.
- the air condenser 100 comprises a heat exchanger 110 which has a cylindrical or prismatic shaped structure which develops in the vertical direction Z.
- the heat exchanger 110 has, for example, an octagonal prismatic shape comprising two walls, respectively, which are constituted by a shaped panel 111 comprising a pair of inlet/outlet conduits 112, 113 for a refrigerating fluid, which extend in the vertical direction Z and act as uprights, and a plurality of bundles or turns of micro-channels alternated with fins along the vertical direction Z (not shown).
- the panels which form the walls 111 are folded so as to form four sides of the perimeter of an octagon.
- the heat exchanger 110 is formed by abutting two walls 111 in the perimeter direction.
- the heat exchanger 110 has a modular structure comprising two pairs of superimposed panels in the vertical direction Z. It will be understood that this configuration of the heat exchanger 110 is not binding for the invention.
- the condenser 100 further comprises a suction device 120 provided with a motorized fan 121 housed in a frame 122 having a generally cylindrical shape.
- This suction device 120 is disposed on the top of the heat exchanger 110.
- the frame 122 surmounts the heat exchanger 110 and is open at the bottom to allow fluid communication with it.
- a safety grid 123 is arranged between the frame 122 and the heat exchanger 110.
- the capacitor 100 further comprises a distributor element 130 with controller function F of an air flow sucked by the suction device 120 transversely through the walls of the heat exchanger 110 and then in the vertical direction Z.
- the distributor element 130 is housed inside the heat exchanger 110 coaxially with it.
- the distributor element 130 is constituted by a plurality of conduits coaxially arranged one to the other. These conduits, which in the illustrated embodiment are five, for example, and have a cylindrical shape, respectively indicated by the reference numerals 131a-131e, have a progressively increasing height from the top to the bottom of the condenser 100 and a progressively decreasing transversal dimension.
- the configuration of the distributor element 130 is such that, by starting from top towards the bottom or base of the heat exchanger 110, a plurality of through openings is defined therein in the vertical direction Z, whose areas are nominally identical, as will be explained more in detail below.
- the through openings are, for example, circular crowns.
- the frame 122 of the suction device and the first one of the conduits 131a are defined in the vertical direction Z, of the through openings A1-A5 through which the air flow F, passing through the walls of the heat exchanger 110, is axially sucked.
- the distributor element 130 is spaced from the bottom of the heat exchanger, whereby a further through opening A6 coincides with the cross-section of the conduit 131 and with a smaller transverse dimension.
- FIGS. 2 and 4 schematically show the path of the airflow F transversely through the walls 111 of the heat exchanger 110 and then axially or vertically through the through openings A1-A6 of the distributor element 130.
- the heat exchanger 110 is ideally divided into a plurality of sectors in which the suction of the air flow F is respectively managed by the through openings A1-A6.
- the overall height "H" of the heat exchanger 110 is subdivided into n sectors He 1 -Hen having nominally the same height. In the illustrated embodiment there are for example six sectors, Hcl-Hc6.
- conduits 13 la- 13 le extend respectively to the boundary between a sector Hc(i) and the subsequent sector Hc(i + 1).
- the number of conduits is equal to the number of sectors less than one, for which the last sector Hen is completely free from the distributor element 130.
- the calculation of the plan dimensions of the conduits 13 la- 13 le is carried out on the basis of the areas of the through openings. Being “Apt” the area of the opening passing through the interface between the suction device 120 and the heat exchanger 110, which represents the total or overall passage area of the air flow sucked by the suction device 120, the area of the generic through opening "Ax" is calculated according to the following formula:
- Ax Apt / (number of sectors - 1)
- the through openings are therefore nominally identical with each other.
- the conduits 131a- 131e are arranged so as to be offset from each other in the vertical direction Z, which favors the formation of air vortexes by the fan of the suction device 120. More particular the duct 131a having the larger transverse dimension and the lower height is arranged in the vicinity of the top of the heat exchanger 110 immediately under the frame 122 of the suction device 120. The other conduits 13 lb-13 le are progressively spaced from the first conduit 131a and one from the other in the vertical direction Z.
- an imaginary line s which touches the top edges of the conduits 13 la- 13 le is inclined towards the bottom of the heat exchanger 110 at an angle between 30° and 60°, for example 45° as in the illustrated embodiment.
- This configuration allows to provide an adequate volume for the formation of air vortexes by the fan of the suction device 120 without making the distributor element 130 in the vertical direction Z excessively cumbersome.
- the suction device 120 generates inside the heat exchanger 110 a depression such as to suck the air flow F through the finned walls from the outside.
- the configuration of the distributor element 130 and the arrangement of the conduits 131a- 13 le and their openings A1-A6 in the vertical direction Z is such to equalize the flow rate F from the bottom to the top of the heat exchanger 110 minimizing the concentrated pressure drops.
- le coatings made of a sound-absorbing material may be advantageously applied, for allowing a reduction of the overall noise of the air condenser 100.
