Typical air stream is come illustrated by the figure under each terminal device 22 of Fig. 7 A-9B to pressure differential characteristic.Be to be understood that air velocity rate and the maximum air velocity rate of minimum will depend on size and the specification of selected air throttle regulator 71,72,73 and 74 respectively.User will depend on that system 10 is used for environment wherein or application for the selection of suitable constant air throttle regulator 71-74.In a kind of illustrative embodiment shown in Fig. 7 A-7B, minimum air flow speed can be in the magnitude of at least 10 cubic feet/min (" CFM "), and the air velocity rate of maximum can be less than or equal to about 400 cubic feet per minute, but these will be different according to described application.

Return Fig. 5, it should be noted that when air throttle 58 is in the closed position shown in Fig. 6, air throttle 58 comprises the flat elements 58b of the usual circle be positioned in the first plane P 1.Time in the opening 59 that the wall 58d that constant air throttle regulator 72 is contained in flat elements 58b limits (Fig. 4), this constant air throttle regulator 72 is arranged in the first plane P 1 or is directly in the air flow path (Fig. 4) of air of the opening 32 flowing into shell 24.When air throttle 58 is in the closed position shown in Fig. 5 and 6, air stream regulates and controls, allows or control to constant rate of speed by this constant air throttle regulator 72, and this speed is represented by the specification of user-selected constant air throttle regulator 72.Therefore, be to be understood that when air throttle 58 starts to open position from closed position (as shown in the shade of Fig. 5 and the diagram of Fig. 7 A-7B and 8A-8B), air throttle regulator 72 is removed by from air flow path, removes minimum or constant air throttle regulator thus from opening 32 with from section or the air flow path between region 14 and pipeline 18.

Be to be understood that one of constant air throttle regulator 72 and 74 or two can to use with different combinations, the such as present illustrative combination will described about Fig. 7 A-9B.Be to be understood that to be easy to expression, the diagram of Fig. 7 A-9B shows element or the carrier 42 of motion valve assemblage 40 (Fig. 4) and the usual U-shaped removed from shell 24.

In the embodiment shown in Fig. 7 A-7B, constant air throttle regulator 72 is arranged in each air throttle 58 be connected with each section or region 14.Constant air throttle regulator 74 is arranged in each pipeline 18, as directed.In the diagram of Fig. 7 A-7B, fan 16 runs continuously with the first fan speed, provides the constant draft air stream of first rate.As shown in Figure 7 A, when air is from section or region 14 flow ipe 18, this air flows through both constant air throttle regulator 72 and constant air throttle regulator 74.When the discharge air from fan 16 is such as forced through pipeline 18 from each section or region 14, constant air throttle regulator 72 provides the first constant air flow that is predetermined or minimum level and regulates and controls.When requiring or need to increase the ventilation in far field 14, such as, when the user's starting switch 54 in a region 14 is to open position (as shown in Figure 7 B), the air throttle 58 in region 14 is needed to be driven into open position by engine 52.This demand of fan 16 perception, and speed is increased to the second fan speed.Air throttle 58 in other far fields 14 maintains the closed position, shown in as shown in Figure 7 B two leftmost air throttle regulators 72.These adjusters 72 provide constant air current control or the regulation and control of the first predetermined or minimum level, and it is represented by the specification of those constant air throttle regulators 72.It should be noted that the air stream increased through those constant air throttle regulators 72 result in blade 72a (Fig. 4) partially enclosed (as shown in Figure 7 B), thus air current control or regulation and control are arrived the speed expected.Substantially simultaneously, it should be noted that in Fig. 7 B of right hand portion, constant air throttle regulator 72 in air throttle 58 has started to open position and has removed from air flow path, allows thus to increase the air stream entering and pass pipeline 18 from region 14, as directed.Second constant air throttle regulator 74 is by air current control or regulation and control to the second predetermined maximum horizontal, and the constant air throttle regulator 72 be connected with other sections or region 14 is by air current control or regulate and control to first or minimum level.

Therefore, system 10 in the embodiment of Fig. 7 A-7B provides means, for by the air stream regulation and control in non-required region or section 14 or control to the first predetermined or minimal flow speed, and needing in section or region 14 is being needed to regulate and control in process in period between the first predetermined or minimum-rate and the second predetermined or maximum rate.In other words, the constant air throttle regulator 72 in Fig. 7 A-7B is conducive to passing the air current control of each pipeline 18 or regulating and controlling or minimum-rate predetermined to substantial constant.Need the ventilation needs in region 14 (need to increase and ventilate) interim here at those, such as, when user's starting switch 54, air throttle 58 starts to open position.As shown in Fig. 7 B rightmost assembly, at least one fan 16 or ventilation blower 17 response pressure reduce and fan speed increases, cause air stream with increase or the speed increase that needs, it is responded.The ventilation which results in from region 14 (needing the ventilation increased here) increases and passes pipeline 18, and finally arriving the discharge duct 19 be connected with building 12.The while of substantially, constant air throttle regulator 72 in two leftmost pipelines (when from left to right observing in figure 7b) regulates and controls and controls the air stream through pipeline 18, and therefore air stream continues with the substantially invariable speed of height to minimum air flow speed (it is represented by selected constant air throttle regulator 72).Air stream in system 10 be each by adjuster 72 and 74 under figure come illustrated.

When the air throttle 58 in Fig. 7 A-7B is closed, maximum air flow restriction or regulation and control are arrived this specification by constant air throttle regulator 72 or 74 (it has minimum maximum air flow specification).If the constant air throttle regulator 72 in such as Fig. 7 A allows maximum 10 cubic feet per minute, and constant air throttle regulator 74 allows maximum air flow 50 cubic feet per minute, then when air throttle 58 is in the closed position, in the figure shown in Fig. 7 A, air stream will by regulation and control to 10 cubic feet per minute.When one of air throttle 58 in system 10 is opened, be arranged on constant air throttle regulator 72 on this air throttle by from air flow path except going to (Fig. 4) in opening 32, allow the air stream being greater than 10 cubic feet per minute thus.When fan 16 or ventilation blower 17 cause air stream to increase, the air stream through pipeline 18 regulates and controls to height to aforementioned maximum 50 cubic feet per minute speed by adjuster 74.Air stream is illustrated by the figure relevant to the air throttle 58 shown in Fig. 7 A-7B to pressure characteristic.

Return see Fig. 9 A and 9B, show another illustrative embodiment.In such an implementation, adjuster 74 is arranged in pipeline 18, but adjuster 72 is not in air throttle 58.In such an implementation, air throttle 58 and wall 58d are solid, and only adjustment in use device 74.At normal operation period, when do not require or need to ventilate or exhaust time, such as allow air throttle 58 to be solid, to maintain the closed position and not through the ventilation of pipeline 18.Fan 16 or ventilation blower 17 provide air stream or open, and to respond user's starting switch 54, it causes engine 52 and air throttle 58 is driven into open position from closed position.When requiring or need to be vented, user's starting switch 54 and air throttle 58 starting switch 62 (as previously mentioned) open fan 16 or ventilation blower 17, air stream are increased to the speed of needs.In such an implementation, the leftmost ducted air stream of two shown in Fig. 9 B lasts till and to be closed by solid air throttle 58.The rightmost air throttle 58 of opening of Fig. 9 B is opened, but air current control or regulation and control are arrived aforesaid second predetermined or maximum rate by adjuster 74.The air stream specific pressure that the figure relevant with air throttle 58 shows this embodiment is poor.

Fig. 8 A and 8B shows another embodiment.In this illustration, constant air throttle regulator 74 removes from system 10.When air throttle 58 is in the closed position, adjuster 72 allows the minimal flow speed entering pipeline 18.When an air throttle 58 is driven into open position by engine 52, as shown in air throttle 58 rightmost in Fig. 8 B, then in the pipeline 18 be connected with the air throttle 58 of this opening, allow the air stream do not regulated and not controled.Constant air throttle regulator 72 in other air throttles 58 provides air current control and regulates and controls to the first predetermined or minimum level, if the air stream in Fig. 8 A and 8B is to shown in tonogram.

The embodiment of the embodiment of Fig. 7 A with 7B with Fig. 8 A with 8B is compared, notice that the constant air throttle regulator 72 that is connected with the rightmost pipeline 18 shown in Fig. 7 B is removed by from the guiding air flow path entered between the section of pipeline 18 or region 14, allow thus to increase the air stream through pipeline 18.The second constant air throttle regulator 74 in Fig. 7 B is by the air current limit of the maximum through pipeline 18 to the second scheduled volume or maximum rate, and it is specified by this constant air throttle regulator 74.Substantially simultaneously, the constant air throttle regulator 72 be connected with two Far Left pipelines 18 (as seen in fig. 7b) in region or section 14 (not needing here to ventilate) continues the amount of air stream to be restricted to minimum level amount.Thus, it should be noted that the blade 72a be connected with two leftmost pipelines is closed a little, thus air stream is restricted to the specification of those constant air throttle regulators 72.

On the contrary, the embodiment in Fig. 8 A and 8B does not have adjustment in use device 74.So, the inflow that air does not regulate and control with flow through the pipeline 18 that is connected with air throttle 58 in the region needing to ventilate or section 14.In the pipeline 18 be connected with that open air throttle 58, do not provide maximum air flow to control or regulate and control.

Therefore, be to be understood that system 10 can have one or more constant air throttle regulator 72 and 74, it is in different combination and permutation from solid air throttle 58, and it has the adjuster 72 that is arranged on wherein by the air stream regulation and control in region 14 or control to the minimum and/or maximum horizontal of substantial constant.When needed, when user wishes the air stream such as vent air stream in section or such as bathroom, region 14 with increase, air throttle 58 can start to open position from closed position.

Be to be understood that adjuster 71-74 and the feature of different embodiments in Fig. 7 A-9B can mix or exchange, and be provided in individual system.A kind of combination of signal is presented in Figure 12 A-12B.Such as system 10 can have air throttle 58, and it has adjuster 71 or 72, has or do not have adjuster 73 and 74.Some air throttles 58 can have solid flat elements 58b and not have opening 59, be similar to the air throttle in Fig. 9 B, and other air throttles 58 and adjuster 72 and 74 diagram as shown in Fig. 7 A-8B can provide.

As previously mentioned, although be to be understood that the system 10 and method that show and use switch 54 (it can be started by user), but also can use other device, for energy supply and ato unit 52, air throttle 58 is driven into open position from closed position.Such as system 10 can use any suitable device to provide engine control signal, for controlling engine 52, and such as switch 54, dehumidifier or take sensor (it is sensing when occupant enters or withdraw from a room), timer, CO ²any combination of sensor or aforementioned means.

Favourable, a feature of shown embodiment be that it provides by from section or region 14 through the vent air stream regulation and control of at least one or more pipeline 18 or control to maximum air flow speed or less or minimum and maximum air flow speed.It should be noted that allow the step from the air stream of fan 16 or ventilation blower 17 to use, one or more constant air throttle regulator 72 or 74 is passive to carry out.

Favourable, foregoing embodiments provides a kind of main flow controller or adjuster, and it is in the form of air throttle 58 and at least one or other flow governors multiple or adjuster, such as constant air throttle regulator 71 and 72.These air throttle regulators can be used alone or combinationally use with another constant air throttle regulator 73 or 74.

As previously mentioned, an advantage of the embodiment of Fig. 4-6 safeguards the system being much better than prior art, because assembly 40 can remove completely from shell 24, and without the need to shell 24 or terminal 22 being taken apart with any pipeline or axle.It should also be understood that constant air throttle regulator 71-74 needs little or do not need to safeguard, this is different from electricity in the past and mechanical system.

If must carry out any repairing or maintenance, then shell 24 is without the need to taking apart from pipeline 18.Flow control apparatus such as adjuster 72 and 74 does not need directly electronic or pneumatic power source, and can by only using system pipeline pressure to regulate and control and controlling air stream.Therefore, even without the power to switch 54 or engine 52, adjuster 72 and/or 74 is also by continuation regulation and control air stream.

Another feature of embodiment is a small size for terminal device 22, and it has size 10 " × 1 " × 8 ".Terminal device 22 can be installed between floor and ceiling structure, such as, by 16 " those constructed by supercentral conventional joist.

Because system 10 can regulate and control and control the air stream in different sections or region 14 as required, therefore the whole capability requirement to central fan 16 and/or ventilation blower 17 can be reduced, because system 10 can at the air stream not needing to provide constant air flow in region 14 and need to provide in those regions of air stream or the ventilation increased desired rate wherein.This makes less fan 16 or ventilation blower can be used in system 10.

What system 10 was favourable provides flow control apparatus, and air stream regulates and controls to constant level when being exposed to the pipeline pressure of change by it.

In described diagram, the first cross section 114a (Figure 13 B) and the second cross section 114b limits the first hole 126 and the second hole 128 respectively.First and second holes 126 and 128 are normally circular, and be changed, sizing and size receives usual cylindrical sub-pipes or duct extensions 130 and 132 respectively.In figure 13a it should be noted that sub-pipes or duct extensions 130 and 132 are with fragment figure display, be easier to make its inner part see and understand.Sub-pipes or duct extensions 130 and 132 comprise radial flange 130a and 132a, and it is respectively at the cylindrical part 130b usually extended, and overall formation in 132b, as shown in the best in Figure 13 C.At the cylindrical part 130b of the extension of sub-pipes or duct extensions 130 and 132, after 132b is contained in hole 126 and 128 respectively, flange 130a and 132a connects with wall 114 and is located against it, as shown in fig. 13 c.The securing member 136 of at least one or multiple routine may be used for sub-pipes or duct extensions flange 130a and 132a to be fixed on wall 114.Also can use that other such as weld for fastening means, binding agent etc.After mounting, notice that sub-pipes or duct extensions 130 and 132 usually extend in parallel and be in Region control terminal device 102.

Favourable, described embodiment shows shell 103, and it limits pipeline, the multiple pipeline of this pipeline Bao Na, that is, sub-pipes or duct extensions 130 and 132.As previously mentioned, sub-pipes or duct extensions 130 and 132 can be same size, shape or dimension, but as directed, are to be understood that they can adopt different sizes, area, shape or dimension.Such as, they can be different length, diameter, size etc.

In described diagram, each Bao Na of cylindrical part 130b and 132b of the usual extension of sub-pipes or duct extensions 130 and 132 and contain at least one or multiple air regulator, the constant air throttle regulator of such as previously described type.Thus, it should be noted that sub-pipes or duct extensions 130 and 132 comprise at least one constant air throttle regulator 140 and 146 respectively, its substantially as relate to foregoing embodiments before this constant air throttle regulator as described in run.

In described diagram, sub-pipes or duct extensions 130 also comprise at least one air throttle 142, it comprises fixed support 142a (Figure 13 C), it is connected on air throttle 142 by driving the driving shaft 54a ' of engine 52 ', under this air throttle is in the control of switch 54 ', and air throttle 142 is started between the open position shown in the closed position shown in Figure 13 A to Figure 13 D.After this function and the operation of air throttle 142 will be described.

It should be noted that sub-pipes or duct extensions 130 also comprise at least one second air throttle regulator 146.The operation of sub-pipes or duct extensions 130 and air throttle 142 and at least one the second air throttle regulator 146 and function class are similar to and relate to before this described in the illustrative example shown in Fig. 9 B.When air throttle 142 is when starting to open position (Figure 13 D) by engine 52 ' from closed position (Figure 13 A), air stream is released and flows through the first sub-pipes or duct extensions 130, and this air stream is regulated and controled by least one second air throttle regulator 146.Therefore, be to be understood that air throttle 142 and at least one second air throttle regulator 146 are series connection, and work in coordination with to provide cubic feet per minute to arrive pressure differential, be similar to shown in Fig. 9 B.

Sub-pipes or duct extensions 132 also comprise at least one first air throttle regulator 140, and playing a role the air stream controlled through the minimum of Region control terminal device 102 and maximum, is also even like this when air throttle 142 is in the closed position shown in Figure 13 A.On the contrary, it should be noted that when air throttle 142 is in the open position shown in Figure 13 D, air is also allowed to flow through sub-pipes or duct extensions 130, and is specified through the maximum air flow speed of sub-pipes or duct extensions 130 or cubic feet per minute by least one second air throttle regulator 146 or controlled.Therefore, when air throttle 142 is in the closed position, at least one first air throttle regulator 140 controls or allows air stream that is predetermined or minimum to pass Region control terminal device 102.When air throttle 142 is in an open position (Figure 13 D), at least one second air throttle regulator 146 and at least one first air throttle regulator 140 work in coordination with to control or allow air stream through Region control terminal device 102, and at least one first and second air throttle regulator 140 and 146 works in coordination with to allow the air stream of predetermined maximum through Region control terminal device 102.Therefore, therefore the air stream being to be understood that through the predetermined maximum of Region control terminal device 102 be the maximum air flow speed sum of at least the first air throttle regulator 140 and at least one the second air throttle regulator 146.Sum up foregoing teachings, should be readily appreciated that lower Table I:

Table I

Therefore, be to be understood that when air throttle 142 is opened, at least one second air throttle regulator 146 is always connected with air throttle 142, and be parallel at least one first air throttle regulator 140, and allow the maximum air flow speed flowing through Region control terminal device 102 to be the maximum air flow speed sum of at least one first air throttle regulator 140 and at least one the second air throttle regulator 146.Such as, if each permission air traffic specification with 10-175 cubic feet per minute of these at least one first and second air throttle regulators 140 and 146, then when air throttle 142 is in the closed position shown in Figure 13 A, maximum air flow through Region control terminal device 102 is controlled by least one first air throttle regulator 140, and becomes 175 cubic feet per minute.But, if air throttle 142 has responded the needs in concrete section or region 14 ' and started to open position, then the maximum air flow through Region control terminal device 102 has become 350 cubic feet per minute (maximum air flow 175 cubic feet per minute of at least one the first air throttle regulator 140 adds maximum air flow 175 cubic feet per minute of at least one the second air throttle regulator 146).On the contrary, it should be noted that in previously described embodiment, air throttle regulator is arranged in series, and in fact minimum air flow adjuster is arranged in air throttle 142 in one embodiment.Maximum air flow speed is limited to the highest maximum air flow speed of the air throttle regulator of series connection in such embodiments.

Favourable, air throttle regulator 140,146 can have identical specification, but more typical, and they have different minimum and maximum air flow rate requirements, may be used in this embodiment.This can be conducive to Region control terminal device 102 to customize or be adapted to concrete environment or structure.Such as generally do not using, but suddenly in the environment of crowded with people or room (auditorium in such as building), desirably provide high maximum air flow speed, it allows large air stream through Region control terminal device 102.

It should also be understood that one or more features of previously described embodiment can use together with the embodiment described in Figure 13 A-13D.Such as at least one the 3rd air throttle regulator can be placed in air throttle 142, is similar to shown in embodiment shown in Fig. 6 and described.It should also be understood that other air throttle regulators one or more can be arranged in wall 114 or other sub-pipes or duct extensions (not shown), its be the mode that is similar to sub-pipes or duct extensions 130 and 132 to be installed among wall 114 or on.In other words, wall 114 may be used for supporting than the sub-pipes of two shown in Figure 13 A-13D or the more sub-pipes of duct extensions 130,132 or duct extensions.When air throttle 142 starts to open position, air throttle 142 can start air throttle switch, as previously mentioned.

It should also be understood that sub-pipes or duct extensions 130,132 can adopt other shape and form, and can be identical or different sizes.In the diagram shown in Figure 13 A-13D, the length of the first sub-pipes or duct extensions 130 and diameter are greater than the second sub-pipes or duct extensions 132.Larger diameter allows at least one second air throttle regulator 146 to be greater than at least one first air throttle regulator 140.Selectable, this sub-pipes or duct extensions can be same sizes, or same can be different sizes.In described diagram, at least one first air throttle regulator 140 is less, and has the maximum air flow speed lower than at least one the second air throttle regulator 146.
