This disclosure relates generally to air diffusion, and more particularly to a system operating with an air conditioning facility, for generating uniform diffusion of conditioned air with the ambient air.
Use of air conditioning for cooling or heating purposes in residential premises, offices, gyms, supermarkets, hospitals etc. has been gaining popularity. Air conditioning systems installed in these premises include some openings provided in a wall or under the ceiling from which conditioned air is forced to exit into the premises. Further, some fixed or movable wings may be provided near the openings to help direct the flow of conditioned air (cold or hot) in a particular direction. However, the flow of conditioned air is majorly in only one direction. As such, the entire flow of the conditioned air is concentrated in a specific area in the direction of the air flow. This concentrated flow of conditioned may cause discomfort and health issues to the persons occupying that specific area.
Further, openings for air conditioning are generally placed at the top region of the wall or are mounted on the ceiling. For heating it would be more effective to introduce the flow of hot air from bottom of the openings, since hot air tends to go up. However, the conventional diffusors lack any provisions for selectively changing the point of introduction of the conditioned air for maximum effectiveness.
Therefore, it is desired to provide a mechanism for wide diffusion of the conditioned air inside the premises and also selectively regulating the flow of conditioned air independent of the air conditioning facility.
In an embodiment, a system for generating uniform diffusion of air is disclosed. The system may include a diffuser tube having a first elongated profile and a first surface extending along a longitudinal length of the diffuser tube and defining a first enclosed space. The diffuser tube may receive conditioned air within the first enclosed space. The first surface includes a first plurality of openings that allow movement of air across the first surface. The longitudinal length of the diffuser tube is changeable. The system may additionally include an external casing having a second elongated profile and a second surface extending along a longitudinal length of the external casing and defining a second enclosed space. The external casing may encase the diffuser tube. The second surface may include a second plurality of openings that allow movement of air thereacross. The external casing may be rotatable relative to the diffuser tube.
In another embodiment, a diffuser tube for generating uniform air diffusion is disclosed. The diffuser tube may include a first elongated profile defining a first surface extending along a longitudinal length of the first elongated profile and a first enclosed space. The first surface may include a first plurality of openings. The diffuser tube may be configured to receive conditioned air within the first enclosed space via at least one inlet. Each of the first plurality of openings may be configured to allow movement of air across the first surface. The longitudinal length of the diffuser tube may be changeable.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate exemplary embodiments and, together with the description, serve to explain the disclosed principles.
Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims. Additional illustrative embodiments are listed below.
As discussed above, it may be desired to provide a mechanism for wide diffusion of the conditioned air inside premises. To this end, the present disclosure provides for a system for generating uniform diffusion of air in the surroundings of the system. Further, the system of the present disclosure provides for increasing or reducing the amount of conditioned air supplied by the system.
The system includes a diffusor tube having openings all around it. These openings may be selectively covered, to thereby allow for reducing or increasing the air flow. To this end, the diffuser tube may include an assembly of telescopic tubes, each of which is slidable relative to the remaining of the telescopic tubes, to thereby change the length of the diffuser tube. Alternately, the diffuser tube may include a helicoidal structure which is collapsible and expandable to change the longitudinal length of the diffuser tube. An orientation of the openings of the diffuser tube may not be exactly perpendicular to the surface of the diffuser tube and the sizes of these openings may vary relative to each other, to further help in the uniform diffusion of air. Further, in some embodiments, the diffuser tube may be rotatable on its axis to generate a better air circulation. An actuating mechanism may be provided to cause change in the length of the diffuser tube and therefore increase or reduce the air flow.
Additionally, the diffusor tube may be encased within an external casing. The external casing may include several openings all around it. Further, the external casing may be rotatable on its axis to generate a better air circulation. Furthermore, an orientation of the openings of the external casing may not be exactly perpendicular to the surface of the external casing and the sizes of these openings may vary relative to each other, to further help in the uniform diffusion of air. Moreover, the openings may add to the external aesthetics of the system.

The system 100 may include a diffuser tube 102. In some embodiments, as shown in
The diffuser tube 102 may be configured to receive conditioned air within the first enclosed space S1 via at least one inlet 114. For example, as shown in
The diffuser tube 102 may further include a first plurality of openings 106 provided on the first surface 104 of the first elongated profile. The first plurality of openings 106 may be distributed along the entire longitudinal length of the diffuser tube 102. Each of the first plurality of openings 106 may be configured to allow movement of air across the first surface 104. In other words, the first plurality of openings 106 may allow for crossing of the conditioned air from within the first enclosed space S1 across the first surface 104, to outside of the first enclosed space S1. Further, the first plurality of openings 106 may be uniformly distributed along the entire longitudinal length of the diffuser tube 102, so as to allow uniform dispersion of the conditioned air from within the first enclosed space S1 to outside of the first enclosed space S1.
In some embodiments, an orientation of each of the first plurality of openings 106 may be oblique to the first surface 104 associated with the diffuser tube 102. In other words, the first plurality of openings 106 may not be exactly perpendicular to the first surface 104 associated with the diffuser tube 102 to allow for effective diffusion of the conditioned air passing through the first plurality of openings 106.
By way of an example, the first plurality of openings 106 may include 1000-2500 openings per square meters of area of the front surface 104. Further, by way of an example, each of the first plurality of openings 106 may have a circular profile, having a diameter of 0.3-0.5 millimeters depending on the size of the diffusor and on the amount of air flow to diffuse. However, the above is only one exemplary embodiment, and in alternate embodiments, openings 106 having different or mixed size can also be implemented. Alternatively, each of the plurality of openings may have any other shape profile including that of a square, rectangular, ovular, etc. In some embodiments, the longitudinal length of the diffuser tube 102 may be changeable. This is explained in detail in conjunction with
The system 100 may further include an external casing 108. The external casing 108 may have a second elongated profile and may include a second surface 110. The second surface 110 may extend along a longitudinal length of the external casing 108 and may define a second enclosed space S2. The external casing 108 may be configured to encase the diffuser tube 102 within the second enclosed space S2.
In some embodiments, as shown in
The external casing 108 may be configured to receive conditioned air within the second enclosed space S2 from the diffuser tube 102, via the first plurality of openings 106. As such, the conditioned air dispersed through the first surface 104 may enter into the space second enclosed space S2. As will be understood, the second enclosed space S2 may include overall volume defined by the second elongated profile minus the volume defined by the diffuser tube 102.
The second surface 110 may define a second plurality of openings 112 provided on the second surface 110 of the second elongated profile. The second plurality of openings 112 may be distributed along the entire longitudinal length of the external casing 108. Each of the second plurality of openings 112 may be configured to allow movement of air across the second surface 110. In other words, the second plurality of openings 112 may allow for crossing of the conditioned air from within the first enclosed space S2 across the second surface 110, to outside of the second enclosed space S2. Further, the second plurality of openings 112 may be uniformly distributed along the entire longitudinal length of the external casing 108, so as to allow uniform dispersion of the conditioned air from within the second enclosed space S2 to outside of the second enclosed space S2.
In some embodiments, an orientation of each of the second plurality of openings 112 may be oblique to the second surface 110 associated with the external casing 108. In other words, the second plurality of openings 112 may not be exactly perpendicular to the second surface 108 associated with the diffuser tube 102 to allow for effective diffusion of the conditioned air passing through the second plurality of openings 112.
By way of an example, the second plurality of openings 112 may include 15-20 openings per square meters of area of the second surface 110 depending on the size of the diffusor and on the amount of air flow to diffuse. However, the above is only one exemplary embodiment, and in alternate embodiments, openings 112 having different or mixed size can also be implemented. Further, by way of an example, and as shown in
The external casing 108 may be rotatable relative to the diffuser tube 102. In particular, the external casing 108 may be rotatable about a central axis XX′ defined parallel to the longitudinal length of the external casing 108. By way of rotation, the external casing 108 may cause a uniform circulation of the conditioned air in the vicinity of external casing 108, i.e. outside the external casing 108. Moreover, in some embodiments, the diffuser tube 102 may as well be configured to rotate about its axis, for uniform dispersion of the conditioned when it is flowing from the diffuser tube 102 into the external casing 108.
In some embodiments, the axis of rotation XX′ of the external casing 108 may be inclined at an angle to an axis associated with the longitudinal length of the diffuser tube 102. In other words, the axis of rotation XX′ of the external casing 108 may not be parallel to the longitudinal length of the diffuser tube 102, for effective diffusion of the conditioned air.
In some embodiments, in order to cause the rotation of the external casing 108 relative to the diffuser tube 102, the system 100 may include a first actuator (not shown in

Further, each of the plurality of telescopic tubes 204 may include a curved surface along its longitudinal length, defining the cylindrical profile. Further, the curved surface of each of the plurality of telescopic tubes 204 may define one or more openings 206, such that each of the one or more openings 206 is configured to allow movement of air across the first surface. It should be noted that the curved surfaces of the plurality of telescopic tubes 204 in combination may define the first surface (corresponding to the first surface 104) of the diffuser tube 202.
Further, at least one of the plurality of telescopic tubes 204 may be slidable relative to the remaining of the plurality of telescopic tubes 204, to change the longitudinal length of the diffuser tube 202. For example, the plurality of telescopic tubes 204 may be slidable with respect to each other along the longitudinal length of the diffuser tube 202. As such, the tube 204B may be slidable within the tube 204A, and similarly the tube 204C may be slidable within the tube 204B. Therefore, by way of sliding of the plurality of tunes 204, the longitudinal length of the diffuser tube 202 can be changed. This is further explained in detail in conjunction with

At step 302, the diffuser tube 202 is configured in fully contracted state. In the fully contracted state, the plurality of telescopic tubes 204A, 204B, 204C may be substantially collapsed into each other. In particular, the telescopic tube 204B may be substantially collapsed into the telescopic tube 204A, and the telescopic tube 204C may be substantially collapsed into telescopic tube 204B. The longitudinal length and therefore the first surface of the diffuser tube 202, in the contracted state, may be the shortest possible length. As such, while the all the openings 206 associated with the telescopic tubes 204A are exposed, only a partial umber of the openings 206 associated with the telescopic tubes 204B, 204C may be exposed. As a result, the amount of conditioned air crossing from the first enclosed space S1 (defined by the diffuser tube 202) into the second enclosed space S2 (defined by the outer casing) is of a lowest possible degree, due to the restricted overall number of openings 206 exposed. Henceforth, the amount of conditioned air crossing from within the second enclosed space S2 to outside the enclosed space S2 is of the lowest possible degree.
At step 304, the diffuser tube 202 is configured in semi-contracted state. In the semi-contracted state, the plurality of telescopic tubes 204A, 204B, 204C may be partially collapsed into each other. In particular, the telescopic tube 204B may be partially collapsed into the telescopic tube 204A, and the telescopic tube 204C may be partially collapsed into telescopic tube 204B. The longitudinal length and therefore the first surface of the diffuser tube 202, in the contracted state, may be of an intermediary length (i.e. somewhere between the shortest possible length and the longest possible length). In particular, the telescopic tube 204B may be partially collapsed into the telescopic tube 204A, and the telescopic tube 204C may be partially collapsed into telescopic tube 204B. As such, while the all the openings 206 associated with the telescopic tubes 204A are exposed, only a partial number of openings 206 associated with the telescopic tubes 204B, 204C may be exposed. In alternate embodiments, in the semi-contracted state, some of the plurality of telescopic tubes 204A, 204B, 204C may be completely collapsed into each other and some of the plurality of telescopic tubes 204A, 204B, 204C may be completely extended. In particular, in the semi-contracted state, the telescopic tube 204B may be completely collapsed into the telescopic tube 204A and the telescopic tube 204C may be completely extended. As a result, the amount of conditioned air crossing from the first enclosed space S1 into the second enclosed space S2 and from within the second enclosed space S2 to outside of the enclosed space S2 is of an intermediary degree.
At step 306, the diffuser tube 202 is configured in fully expanded state. In the fully expanded state, the plurality of telescopic tubes 204A, 204B, 204C may be fully expanded. In particular, the telescopic tube 204B may be fully expanded with respect to the telescopic tube 204A, and the telescopic tube 204C may be fully expanded with respect to the telescopic tube 204B. The longitudinal length and therefore the first surface of the diffuser tube 202, in the fully expanded state, may be of the longest possible length. As such, all the openings 206 associated with each of the plurality of telescopic tubes 204A, 204B, 204C are exposed. As a result, the amount of conditioned air crossing from the first enclosed space S1 (defined by the diffuser tube 202) into the second enclosed space S2 (defined by the outer casing) is of the highest degree possible.
In order to change the longitudinal length of the diffuser tube 202, the diffuser tube 202 may be coupled with the first actuator (not shown in

For example, as shown in
In some embodiments, the sheet and therefore the plurality of helicoidal folds 404 may be flexible to undergo longitudinal translation to effect a change in the longitudinal length of the diffuser tube 402. Therefore, by way of translating of the plurality of helicoidal folds 404, the longitudinal length of the diffuser tube 402 can be changed. This is further explained in detail in conjunction with
Referring now to
At step 502, the diffuser tube 402 is configured in a fully contracted state. In the fully contracted state, the plurality of helicoidal folds 404 may be substantially collapsed into each other. The longitudinal length and therefore the first surface of the diffuser tube 402, in the contracted state, may be of the shortest possible length. As such, a minimal number of openings 406 associated with the diffuser tube 402 are exposed. As a result, the amount of conditioned air crossing from the first enclosed space S1 (defined by the diffuser tube 402) into the second enclosed space S2 (defined by the outer casing) is of a lowest possible degree, due to the restricted overall number of openings 406 exposed. Henceforth, the amount of conditioned air crossing from within the second enclosed space S2 to outside the enclosed space S2 is of a lowest possible degree.
At step 504, the diffuser tube 402 is configured in a semi-contracted state. In the semi-contracted state, the plurality of helicoidal folds 404 may be partially collapsed into each other. As such, the number of openings 406 exposed may be relatively higher than in the fully contracted state of the diffuser tube 402. As a result, the amount of conditioned air crossing from the first enclosed space S1 into the second enclosed space S2 is of an intermediary degree (relatively higher than in the fully contracted state).
At step 506, the diffuser tube 402 is configured in fully expanded state. In the fully expanded state, the plurality of helicoidal folds 404 may be fully expanded. The longitudinal length and therefore the first surface of the diffuser tube 402, in the fully expanded state, may be of the longest possible length. As such, the number of exposed in the fully expanded state may be relatively higher than in the intermediary state of the diffuser tube 402. As a result, the amount of conditioned air crossing from the first enclosed space S1 into the second enclosed space S2 is of the highest degree possible (relatively higher than in the intermediary state).
In order to change the longitudinal length of the diffuser tube 402, the diffuser tube 402 may be coupled with the first actuator (not shown in

In some scenarios, especially when the diffuser tube 606 is operating in contracted state, the entire amount of conditioned entering the diffuser tube 606 may not be exited from the diffuser tube 606 and hence from system 602, due to restricted flow via the contracted diffuser tube 606. The leftover conditioned air may therefore be exited from the system 602 via the output air duct 614 into the duct line 610.
As mentioned above, the length of the diffuser tube 606 may be changeable, depending on the amount of air flow required from the system 602. Further, the external casing 608 may be rotatable relative to the diffuser tube 606, to cause a uniform circulation of the air in the vicinity of external casing 608. In order to cause the change in length of the diffuser tube 606, the system 602 may include a first actuator 616 coupled to the diffuser tube 606. In some embodiments, as explained via
Alternately, the system 602 may further include a second actuator 618 coupled to the external casing 608. The second actuator 618 may be configured to cause the rotation of the external casing 608 relative to the diffuser tube 606. In other words, the system may include two separate actuators. The first actuator 616 may perform the functionality of changing the longitudinal length of the diffuser tube 606, and second actuator 618 may perform the functionality of rotating the external casing 608 relative to the diffuser tube 606.
The above disclosure discloses one or more techniques for generating uniform diffusion of air, for example, conditioned air received from an air conditioning facility. The above techniques provide for a system which includes a diffuser tube or a diffuser tube along with an outer casing configured in a cylindrical profile. The conditioned air (e.g. conditioned air received from the air conditioning facility) is exited (diffused) through perforations provided on the surface of the diffuser tube or the outer casing. The above system exits the conditioned air in all the directions (360°) around the cylindrical length of the diffuser tube or the outer casing, thereby uniformly diffusing the conditioned air in all directions, rather than concentrating the flow of conditioned air in only one direction. As such, the requirement of introducing hot air in downward direction is also met. In other words, the above system provides for selectively changing the point of introduction of the conditioned air for maximum effectiveness. Furthermore, the above system allows for reducing or increasing the air flow, by changing the length of the diffuser tube, using actuating mechanism. Moreover, the external casing is rotatable on its axis to generate a better air circulation. Further, by providing orientation of the openings of the diffuser tube oblique (not exactly perpendicular) to the surface of the diffuser tube and variable sizes of the openings further help in the uniform diffusion of air. Furthermore, the external casing adds to the external aesthetics of the system. Moreover, it is possible to fluidically couple multiple diffuser tubes to distribute the conditioned air therebetween to thereby optimize air conditioning, based on the regulation of each diffusor. Further, the above system provides for silent operations of diffusion.
It is intended that the disclosure and examples be considered as exemplary only, with a true scope and spirit of disclosed embodiments being indicated by the following claims.
