Definitions

  • ABSTRACT A first housing is provided, together with a similarly dimensioned second housing. Heat exchange elements V are provided in the first housing for the purpose of conditioning the ambient air, and a humidifying arrangement is provided in the interior of the second housing and occupies a substantial portion of this intenor.
  • the present invention relates generally to installations for the conditioning of air, and more particularly to an installation capable of heating and/or cooling the ambient air.
  • a further development of this type of unit is provided in addition with a ventilating means, usually arranged in a bottom portion of the casing and most frequently constructed as radial-flow blowers.
  • the purpose here is to provide for a significantly improved heating of the ambient air due to the movement of the ambient air by the blower as opposed to ordinary air movement by convection.
  • each unit as a separate entity, and to connect as many of the units as are necessary for obtaining a desired heating and/or cooling effect, that is as many as are necessary to heat and/or cool a given room area.
  • the cases or housings of these units are usually placed close together or into abutment, being connected with one another by screws or similar connecting means, and the conduits in the-individual units are connected with one another for circulation of the heat exchange fluid therein.
  • Another object of the invention is to provide such an installation which provides for the desired humidification of the air, and which is either free from or at least requires only minimum maintenance and at the same time serves to remove pollutants from the ambient air.
  • one feature of the invention resides, in an installation for the conditioning of air, in a combination which briefly stated comprises a first housing and a similarly dimensioned second housing. Heat exchange means is provided in the first housing for conditioning the ambient air, and humidifying means is provided in and occupies a substantial portion of the interior of the second housing.
  • the second housing can be used in effect as a component or module in the construction of an installation for the conditioning of air. If it is assumed, for instance, that two of the first housings with their associated heat exchange means are required for providing the desired amount of heating and/or cooling of a given space, then the second housing with the humidifying means according to the present invention can be combined with them in the manner of a module, to thereby provide the desired humidifying action.
  • the invention provides for considerable freedom of a combination, that is if for instance two of the first housings with their associated heat exchange means are provided, then the second housing with the humidifying means may be located between the two first housings, at one end of a row composed of the three housings, at the other end, or in any desired relationship.
  • the second housing may be composed of two sections, one of which is provided with the humidifying means and in the other of which a blower means is provided.
  • the two sections may be so constructed that they can be releasably connected and that the section provided with the humidifier means can be employed by itself in conjunction with one or more first housings. This makes it possible to first provide the section having the humidifying means and, if it is found later to be necessary to provide in addition the section having the blower means, or if for instance financial consideration dictate that the section provided with the blower means be acquired only later, the section with the blower means can then be connected with the section having the humidifying means.
  • the second housing may be provided with at least two conduits of which one is to be connected at its opposite ends with the supply conduit of the heat exchange means in the first housing or housings, whereas the other conduit is to be connected with the returnflow conduit of the heat exchange means in the first housing or housings.
  • the second housing can be located freely wherever desired with respect to the first housing or housings, that is at one or the other side of the first housing, between two of the first housings, or in any desired location. The freedom of positioning of the second housing with reference to the first housing or housings of the installation is therefore vastly increased.
  • FIG. 1 is a somewhat diagrammatic perspective illustrating an embodiment of the invention, with parts broken away for clarity;
  • FIG. la is a fragmentary sectional detail view, showing a portion of FIG. 1;
  • FIG. 2 is a diagrammatic front elevation showing an installation utilizing the invention
  • FIG. 3 is a view similar to FIG. 2 but showing a different installation utilizing the invention
  • FIG. 4 is a vertical fragmentary section illustrating a detail of an embodiment of the invention.
  • FIG. 5 is a fragmentary detailed, on an enlarged scale, illustrating another embodiment of the invention.
  • FIGS. 1-3 DESCRIPTION OF THE PREFERRED EMBODIMENTS Discussing the drawing in detail, and firstly referring to the embodiment illustrated in FIGS. 1-3 thereof, it will be seen that the invention is here illustrated as a module or unit having a housing 1 of substantially boxshaped configuration.
  • the configuration and dimensioning of the housing I is the same as that of the other housings of the installation (see for instance FIG. 2) with which it is to be combined.
  • the housing 1 accommodates in its lower portion a blower 2 which may be of any desired type but which advantageously is a well-known radial-flow blower.
  • a blower 2 which may be of any desired type but which advantageously is a well-known radial-flow blower.
  • the reason for utilizing radial-flow blowers is that they are relatively narrow and long in construction, and provide in a very small space a rather significant air-circulating capacity.
  • Humidifying means here illustrated in form of a receptacle 3, is located in the upper portion of the housing 1.
  • Air circulation openings are provided in the housing 1, in the illustrated embodiment in the front panel at the lower region thereof. These air circulation openings may be in form of elongated slots or in any other desired configuration. It is advantageous to locate behind the openings 10 a removable filter, for instance in form of a filter plate 4 which is retained in a frame 4a (see FIG. la), so that the air which enters through the openings 10 under the aspirating effect of the blower 2, will be filtered before it reaches the latter.
  • filters are already well known and may for instance be in the form of glass fiber mats or the like.
  • the housing 1 may be of two sections, for instance the upper section la and the lower section 1b, with the plane of separation where the two sections meet being indicated at reference numeral It.
  • the upper section la accommodates the humidifying means 3
  • the lower section lb accommodates the blower 2.
  • the arrangement may be such that the upper section la with the humidifying means 3 may be used in conjunction with the other modules of the installation without the lower section 1b and the associated blower 2.
  • the upper section In may be so used and the lower section lb and the blower 2 be omitted permanently, or the lower section lb with its blower 2'may be supplied later if a need for them is found to exist, or if financial considerations make the supplying of the lower section lb and of the blower 2 possible only at a later time.
  • a stationary guide baffle 12 may be provided in the lower section 1b, covering a portion of the blower 2.
  • the baffle 12 may serve to guide and direct air.
  • the baffle 12 may also be provided with adjustable baffles, for instance the adjustable baffles 5 and 6 which in the illustrated embodiment are pivotable about the axis 13 and 13', respectively.
  • the baffles 5 and 6 regulate the supply of incoming air and the supply of outgoing air, respectively.
  • the housing 1 further accommodates two transversely extending pipes 7 and 8. These are to be connected with the supply conduit and return-flow conduit, respectively, of the heat exchange system in other housings of the installation which accommodate the heat exchange portion of the installation.
  • the other housings which will be discussed with respect to FIGS. 2 and 3
  • the pipes 7 and 8 are to be connected with these in order for instance to make it possible to accommodate the housing 1 with its associated components between two housings accommodating heat exchange means, so that the circulation and return flow of heat exchange fluid can take place from a heat-exchange housing at one side of the housing I through the latter to a heatexchange housing located at the opposite side of the housing 1.
  • FIG. 4 shows by way of example how the baffles 5 and 6 can be displaced about their pivot axes 13 and 13', respectively.
  • the pivot axes l3, 13' are constituted by shafts,
  • a threaded spindle 24 connected via a universal or cardanic joint 25 with a turnable knob 26.
  • the spindle 24 is mounted in a nut 27. It will be appreciated that when the knob 26 is turned in one direction the spindle 24 shifts axially of itself due to the fact that it is threaded through the nut 27, causing the arm 60 (on which the nut 27 is pivotably mounted) to become displaced in one direction.
  • FIG. 2 shows how the embodiment according to the present invention can be utilized as part of the installation for the conditioning of air.
  • the housings 1 and 11 are of identical configuration and in the illustrated embodiment they each have an upper portion and a lower portion lb, with the lower portion in each instance accommodating a blower 2.
  • the blowers 2 can all be coupled with one another and in this case only one of them need be connected with the diagrammatically illustrated motor 14 which then drives them all.
  • Only a single blower could be provided in the lower portion 1b of the housing 1.
  • the inlet conduit is identified with reference numeral 2], being controlled by suitable valves 20, and the outlet conduit with reference numeral 22.
  • inlet conduit 21 is connected with one end of the pipe 7 in the housing 1, whereas the other end of the pipe 7 in the housing 1 is connected with the portion of the inlet conduit which is located in the left-hand housing 1 1.
  • the two portions of the outlet conduit 22 provided in the two housings 11 are connected with the opposite ends of the pipe 8 in the housing 1.
  • FIG. 3 another possibility is shown how the housing 1 and its associated components can be combined with two housings 11, it being understood that more than two housings or only a single housing 11 can of course also be provided.
  • the separate lower housing sections accommodating the blowers 2 have been omitted, so that each housing is here of only one section. It is clearly seen that the housings 11 and 1 form a row at one end of which the housing 1 is located.
  • the humidifying means be totally or substantially maintenance free.
  • a contact element 15 extending into the receptacle 3 and closing an electric circuit when the water in the receptacle 3 reaches a certain predetermined level.
  • the circuit may then be connected with a valve 16 in known manner, the valve 16 for instance being magnetically operated and being opened in response to the closing of the circuit to admit additional water into the receptacle 3 via a pipe 16a with which the valve 16 is connected.
  • the supply of water would then continue until a float 17, acting upon the valve 16 via the arm 17', reaches its upper position, indicating that an upper desired water level is achieved, whereupon the valve 16 would be closed.
  • the float 17 can be relied upon to control opening and closing of the valve 16 by itself, that is without the provision of the electric circuit and the contact 15. This is well known from the art and requires no further discussion.
  • the housing 1 is provided in its upper or cover wall 18 with air outlet' openings 19 which may be slotshaped or otherwise configurated, so that water can readily evaporate in the receptacle 3. Evaporation is facilitated if during the heating season hot water or steam passes through the pipes 7 and 8, that is when these are connected with the supply and return-flow conduits of the heat exchange means in the housing or housings 11 with which the housing 1 cooperates. This of course serves to raise the temperature of the water in the receptacle 3 by some degrees, and depending upon the heating effect obtained by the heat exchange means in the housings 11, the humidity in the ambient air is thus self-regulating.
  • Suitable means may of course be provided to connect the housings 1 and 11 with one another, just as suitable means may be provided for connecting the housing portions la and lb with one another.
  • the arrangement of the pipes 21 and 22, the pipes 7 and 8 and the valve 20 may be chosen otherwise than what has been illustrated without thereby departing from the scope and intent of the present invention.
  • the housing is again identified with reference numeral 1. Its rear wall is provided with an opening or cutout 21 located as desired but in the illustrated embodiment located approximately two-thirds of the height of the housing above the lower end of the latter.
  • An inlet pipe 29 extends outwardly from this opening 28, being connected therewith by a suitable flange or the like, and extending into an appropriately insulated opening 30 provided in the wall 31 bounding a room or the like.
  • the outer end of the pipe 29 is closed by a grit or screen 49 which is located at the outer side of the wall 31.
  • a blower 32 in this instance illustrated as an axial-flow blower or fan, is located in the interior of the pipe 29, being operatively associated with an induction motor 33 whose direction of rotation can be reversed in known manner.
  • the induction motor 33 is connected with a switch 35 which can be operated via knob 34, the connection being established via a circuit 36.
  • the knob 34 may be located at an appropriate point of the installation, for instance at the front side of the housing 1 if desired.
  • the closure element 37 is provided between the housing 1 and the blower 32, and the illustrated embodiment being constructed as a turnable element and having cutouts 38 which can be made to register with similar cutouts 39 provided in an intermediate wall 40.
  • cutouts 38 can be made to register with similar cutouts 39 provided in an intermediate wall 40.
  • other configurations can be provided for the element 37, for instance it can be of the sliding type or the like.
  • the embodiment in FIG. 5 omits the arrangement of the stationary and movable baffies illustrated in FIGS. 1-4 and permits a particularly ready installation in a wall of a room whose air is to be conditioned.
  • the housing 1 or the receptacle 3 itself mayaccommodate one or two level switches 41 and 42, being operatively associated with the motor 14 for the blower 2.
  • the arrangement would be such that the switch 41 interrupts the circuit for the motor 42 when the level of liquid in the receptacle 3 drops to a lower limit, and when the level is subsequently restored to an upper limit the circuit for the motor 14 would be automatically completed again by the switch 42.
  • the circuit 36 may be connected with the switches 41 and 42.
  • switches 41 and 42 may also, in connection with a solenoid valve, control the supply of water, for instance if the valve 16 is a solenoid valve which is also known from the art.
  • a combination comprising a first housing having a first side wall, and spaced-apart air inlet and outlet apertures; a second housing dimensioned and contoured similar to said first housing and having a second side wall laterally adjacent to and connected in abutment with said first side wall, said second housing also having spaced-apart air inlet and outlet apertures; heat exchange means in said first housing for thermally conditioning ambient air which enters through said inlet aperture and leaves through said outlet aperture; and humidifying means in said second housing for humidifying the ambient air, including a humidifier containing water which evaporates when heated via said heat exchange means, air circulating means for circulating air over said humidifier in said second housing, a first baffle in said second housing for guiding air entering through said inlet aperture, and a second baffle in said second housing for guiding air towards said outlet aperture.
  • said second housing comprises two discrete housing portions, said humidifier being provided in one and said air circulating means being provided in the other of said housing portions.
