Definitions

  • the present invention relates to a ventilation device for climate control systems.
  • Computer rooms, and in general any site that contains several items of electronic equipment and racks i.e., supporting frames for a plurality of electrical, electronic and similar instruments, generally enclosed within appropriately provided ventilated cabinets
  • require continuous climate control suitable to prevent the heat generated by the computers and electronic instruments from accumulating, generating temperatures that are so high as to damage the internal components of the electronic instruments and the like.
  • underfloor climate control systems are generally installed in computer rooms and are increasingly widespread particularly in environments provided on a raised floor.
  • the interspace between the floor slab and the raised floor can in fact be equipped easily not only for the distribution of the cables for connecting and supplying power to the racks and computers but also as a plenum, i.e., as a passage space for air conditioning, said plenums conveying the air to the overlying environments by means of floor-mounted grilles.
  • the transfer of the cooled air from the plenum to the environment to be climate-controlled occurs mainly by so-called displacement, a principle according to which the stratification of the air according to temperature is used and its penetration into the overlying environment is facilitated by way of the difference in relative density with respect to the warmer air that is already present in the environment.
  • climate control systems for computer rooms which are capable of inducing a forced motion of the cooled air instead of leaving its diffusion to natural stratification are becoming increasingly widespread.
  • these systems are provided not only with the central ventilation unit, which propels the conditioned air into the plenum under the floor, and with the floor-mounted grilles adapted to make said conditioned air flow out into the environment, but also with auxiliary ventilation units, which are arranged predominantly within the interspace between the raised floor and the floor slab, which acts as a plenum.
  • auxiliary ventilation units intensify the efficiency of the central ventilation unit, reducing climate control times.
  • the ventilation devices that constitute such auxiliary units are adapted to convey the conditioned air generically upward, with the risk of obtaining excessive cooling for the computers and racks that lie closer and insufficient cooling, or at least slow cooling, for the computers and racks that are located further from said devices.
  • the aim of the present invention is to provide a ventilation device particularly for climate control systems installed in floors, walls, ceilings and the like, which is capable of obviating the drawbacks shown by known types of ventilation device.
  • an object of the present invention is to provide a ventilation device which can optimize the distribution of the conditioned air in the environment to be climate-controlled.
  • Another object of the present invention is to provide a ventilation device whose configuration can be changed easily even by a user who does not have particular prior training.
  • Another object of the present invention is to provide a ventilation device which can be installed in known panel-type raised floors.
  • Another object of the present invention is to provide a ventilation device which is compact and can be installed even in small interspaces between the floor slab and the raised floor.
  • a further object of the present invention is to provide a ventilation device whose effectiveness and efficiency are at least equal to those of conventional devices.
  • a still further object of the present invention is to provide a ventilation device particularly for climate control systems installed in floors, walls, ceilings and the like, which can be manufactured with known systems and technologies.
  • a ventilation device particularly for climate control systems installed in floors, walls, ceilings and the like, characterized in that it is constituted by a supporting frame for at least one oscillating basket, which is adapted to contain at least one motorized fan for aspirating the conditioned air from a plenum with which said device is associated, said at least one oscillating basket being in turn coupled to said frame with means for the rotation of said basket about at least one axis, said basket being arrangeable with a preset inclination with respect to the arrangement of the floor, wall or ceiling in which the device is flush-mounted.
  • a ventilation device particularly for climate control systems installed in floors, walls, ceilings and the like according to the invention is generally designated by the reference numeral 10.
  • the device 10 is constituted by a supporting frame 11 for two oscillating baskets, respectively 12 and 13.
  • Each of the two baskets 12 and 13 contains two motorized fans.
  • the first basket 12 contains two first fans, which are arranged inside blowers 14 and 15, and the second basket 13 contains two second fans, each arranged inside two additional blowers 16 and 17.
  • the blowers 14, 15, 16 and 17 are adapted to draw conditioned air from a plenum with which the device 10 is associated; the conditioned air reaches said plenum from a central climate control unit, which is not shown for the sake of simplicity.
  • the device 10 is recessed in a raised floor 19, in an interspace 22 between panels 42 that compose it and the floor slab 23; the interspace 22 provides the plenum for feeding conditioned air.
  • Each oscillating basket 12 and 13 in turn is coupled to the frame 11 by way of means for the rotation of said basket about an axis.
  • the two baskets 12 and 13 each rotate about an axis which is parallel to the rotation axis of the other basket.
  • the baskets 12 and 13 therefore can be rotated and positioned with a preset inclination with respect to the plane of arrangement of the floor 19 (or wall or ceiling) in which the device 10 is recessed.
  • Each basket 12 and 13 can be inclined independently with respect to the other basket 12 and 13.
  • the frame 11 has lips 24 for resting on cross-members 20 of the raised floor 19 in which the device 10 is recessed, so that said device is arranged, as mentioned, in the interspace 22 between the floor 19 and the underlying surface, i.e., the floor slab 23; the interspace 22, as mentioned, forms the plenum by means of which the conditioned air reaches the device 10.
  • each basket 12 and 13 are constituted by two coaxial pivots 25 and 26, as shown in Figure 4.
  • the pivots 25 and 26 are adapted to couple rotatably the respective basket 12 and 13 (the first basket 12 is visible in the cross-section of Figure 4) to two supporting brackets 27 and 28, which are mutually opposite with respect to the baskets that they support.
  • the brackets 27 and 28 are rigidly coupled to the supporting frame 11.
  • brackets 27 and 28 are made of punch-cut and bent sheet metal and are fixed to the frame by means of additional threaded elements 36.
  • Each of the pivots 25 and 26 is formed by a threaded element, which is adapted to pass through two holes 29 and 30: the first hole 29 is provided in the bracket 27 and 28, and the second hole 30 is provided in a facing connecting flap 31 of the basket 12 and 13.
  • Each threaded element is screwed to a corresponding complementarily threaded locking female thread element 32.
  • the female thread element 32 is fixed inside the connecting flap 31 of the basket 12 and 13.
  • Each basket 12 and 13 is constituted by a cover made of sheet metal, respectively designated by the reference numerals 12a and 13a, to which the connecting flaps 31 belong; the cup-shaped bodies of the motorized blowers, respectively 14, 15, 16 and 17, hang from the covers 12a and 13a.
  • the covers 12a and 13a have a grille-shaped portion 12b and 13b at each of the underlying fans.
  • the means for the rotation of the baskets 12 and 13 also comprise means for maintaining the configuration on the part of the baskets 12 and 13.
  • Said means for maintaining configuration are constituted by two protrusions 33 and 34, which protrude from the connecting flaps 31 with which each basket 12 and 13 is provided.
  • Each protrusion 33 and 34 is adapted to be inserted reversibly in selectively one of a plurality of holes 35 arranged in a circular arc in the vicinity of the first hole 29 on the facing bracket 27 and 28.
  • Reversible insertion is obtained by elastic deformation of the brackets 27 and 28 and/or the flap 31 on which the protrusions are provided.
  • each connecting flap 31 has two protrusions 33 and 34, which are symmetrical with respect to the rotation axis of the basket 12 and 13 to which they belong.
  • each pair of protrusions 33 and 34 can be inserted reversibly in a corresponding pair of symmetrical holes, designated by the reference numerals 35a and 35b in Figure 3 by way of example, selected among a plurality of pairs of holes.
  • Said plurality of pairs of holes is formed by two arcs of holes 35, which are symmetrically mutually opposite with respect to the axis of the first hole 29, on the facing supporting bracket 27 and 28.
  • Each one of the protrusions 33 and 34 is formed by a stud, which is obtained on the connecting flap 31 to which the protrusions belong, the flap 31 being made of sheet metal, like the cover 12a and 13a, on which the flaps are obtained by bending.
  • the supporting frame 11 is constituted by a box-like body made of sheet metal, which is open on the side directed toward the environment to be climate-controlled.
  • the box-like body is provided with intake grilles 37 and 38 for protection against the suction of any foreign objects from the plenum with which the device 10 is associated.
  • the plenum is provided by the interspace 22.
  • the frame 11 has a grille 37 on each of its faces 39 which lie transversely to the supporting brackets 27 and 28 and two additional grilles 38 on its bottom 40, at the two overlying baskets 12 and 13.
  • the frame 11 has a substantially square shape and its dimensions are such that it can be positioned on a raised floor 19 of a per se known type instead of a panel 42, which together with other identical panels 42 composes the raised floor 19.
  • the device 10 is conveniently closed in an upper region by a grille, preferably of the walkable type 43.
  • the device 10 according to the invention therefore allows to orient each basket 12 and 13 according to the type of distribution of conditioned air to be obtained in the environment to be climate-controlled.
  • the inclination is selected among a plurality of positions set by the number of holes 35 that constitute each arc of holes.
  • the inclination is changed, after releasing the bracket 27 and 28 and the flap 31 from the grip of the threaded elements 25 and 26, by applying to the basket 12 and 13 a torque which makes the protrusions 33 and 34 slide out of the holes 35a and 35b in which they are accommodated.
  • the device 10 is provided with an electric motor drive for the continuous and not stepwise rotation of each basket.
  • the motor drive also comprises the means for maintaining the set configuration.
  • Figures 5 to 8 each illustrate a possible distribution of the stream of conditioned air which can be obtained with a combination of configurations of the baskets 12 and 13.
  • This configuration allows to obtain a greater "fountain" flow, capable therefore of providing direct cooling to regions which lie higher up from the floor 19 with respect to what the baskets 12 and 13 in the configuration of Figure 5 can do.
  • the first basket 12 is parallel to the floor 19, while the second basket 13 is inclined toward the first basket 12; in this manner, the flow 50 concentrates in the region that lies above the first basket 12.
  • both baskets are oriented toward one side and the flow 50 is directed toward a region which is lateral with respect to the device 10.
  • Figures 5 to 8 show how the device 10 can be set up to provide climate control of different regions of the environment according to requirements, i.e., depending on where the computerized units, racks and other similar electronic units to be cooled are arranged and at what height they are located, or depending on the computerized stations of the operators working in a same open space.
  • the possibility to orient the baskets 12 and 13 that characterizes the device 10 according to the invention can therefore be used also to increase the well-being, and therefore the work quality, of several operators working in a single environment, such as for example an open space.
  • the device 10 is provided with a compartment 44 for accommodating a unit for controlling and managing the rotation rate of the motorized blowers 14, 15, 16 and 17.
  • the device 10 is provided with suitable holes, such as the through hole 45 on the bracket 27, for the passage of the power supply cables of the motorized fans.
  • the control and management unit can be interfaced with a network of identical devices 10, mutually controlled according to a configuration of the "master-slave" type.
  • the devices 10 accordingly behave in the same manner.
  • the control panel further allows to manage the speeds of the fans.
  • the plenum is not pressurized, for an equal speed of the fans of the various devices 10 the resulting flow-rate is in fact lower than necessary.
  • the advantage of being able to adjust the flow-rate of the air that flows out of each device 10 also allows energy saving, as in the case in which the racks are not filled to full capacity and the heat to be conditioned is lower than the standards of said racks when fully loaded.
  • the device 10 according to the invention offers maximum flexibility in use.
  • the device 10 in fact merely needs to be connected to an electric power supply, and if it is provided with a power supply cable of suitable length, it may not be indispensable to remove the plug from the socket in order to move it to another socket.
  • the present invention provides a ventilation device which is capable of optimizing the distribution of the conditioned air in the environment to be climate-controlled.
  • the present invention provides a ventilation device whose configuration can be changed easily even by a user who does not have particular prior training.
  • the present invention provides a ventilation device which can be installed in known panel-type raised floors.
  • the present invention provides a ventilation device which is compact and can also be installed in small interspaces between the floor slab and the raised floor.
  • the present invention provides a ventilation device whose effectiveness and efficiency are at least equal to those of known types.
  • the present invention provides a ventilation device particularly for climate control systems installed in floors, walls, ceilings and the like which can be manufactured with known systems and technologies.
  • the materials employed may be any according to requirements and to the state of the art.
