Description

For the channel switching device and airhandling equipment in fluid line

Technical field

The present invention relates to airhandling equipments, and in particular, to a kind of channel switching device in fluid line, this Outside, the invention further relates to a kind of airhandling equipments.

Background technique

Atmosphere polluting problem has increasingly been highlighted in today's society, seriously endangers the health of people, in order to cope with Worsening atmosphere polluting problem, all kinds of airhandling equipments are widely used in family, office building, hospital, school etc., Middle aeration device is using a kind of airhandling equipment more stronger than wide, practicability.Product is main in fresh air industry at present Based on central fresh air system, in addition to this, wall-hanging, cabinet type new blower, the new blower of wall-penetrating type are also applied more.

Central fresh air system includes the host and blast pipe and discharge pipe for being installed on indoor top, foul indoor air warp Discharge pipe discharge is indoor, and outdoor fresh air is sent into interior through blast pipe after the main emission controls by improving combustion of fresh air.One inside fresh air host As blower and filter screen, blower is arranged includes air-introduced machine and exhaust blower to realize two-way circulating for air-flow, some further include full heat Exchanger realizes the portion temperature exchange of room air and outdoor air and adjusting air humidity.

Wall-hanging and cabinet type new blower are that the components such as blower and strainer are integrated in a machine to be formed on host, the host It is typically mounted at interior, by being connected into and out of pipeline with outdoor, general pipeline is shorter, is hidden in invisible in wall.Wind Machine is divided into air-introduced machine and pressure fan, and air-introduced machine introduces foul indoor air by the air port around host shell and room is discharged when work Outside, pressure fan introduces outdoor fresh air feeding interior after filter assemblies (generally multistage strainer) by admission line. In addition, higher wall-hanging is configured and cabinet type new blower generally installs total-heat exchanger additional, to realize room air and outdoor air Portion temperature exchange and adjusting air humidity.

The new blower of wall-penetrating type, is generally mounted on wall or glass, by punching (general diameter on wall or glass 15cm or more) so that new blower is placed in wall or inside glass, outdoor air is introduced by inner fan and passes through filter assemblies (strainer) is sent into interior, and this new blower of wall-penetrating type is generally the one-way flow of air-flow, some products are by controlling fan just The a degree of intermittent interior of reversion realization is exchanged with outdoor air.

Above-mentioned center fresh air system, needs to install a large amount of blast pipes and air-exhausting duct, destroys family's interior trim, greatly occupancy man Front yard space.For wall-hanging and cabinet type new blower, although saving ventilation shaft to a certain degree, its take up space it is larger, Machines cumbersome, power is also larger, consumes energy excessively high, uses very uneconomical.The new blower of wall-penetrating type generally pass through strainer into Row filtering, the low efficiency once filtered, it is difficult to meet the requirement of fresh air, and due to needing integral installation in wall hole, for The diametric requirements of wall hole are excessively high, and practicability reduces, and seriously affect the selection of consumer.

In addition, above-mentioned center fresh air system, wall-hanging and cabinet type new blower are in addition to using strainer as air deduster Except, it is some of also using electrostatic dust collection equipment as air deduster, but these electrostatic dust collection equipments be confined to it is quiet The natural mode that electric field is formed uses the plate of traditional parallel interval opposed type to form electrostatic field, leads to these new blowers It is bulky, occupied space is excessive, and the air stream to dedusting it is straight quickly through, frequently result in air cleaning efficiency compared with Low, the New atmosphere quality of introducing is often inferior, influences human health, this causes using the new blower of these electrostatic dust collection equipments in city Acceptance is relatively low on field.In addition, using the new blower of electrostatic dust collection equipment, there is also some influence human healths, those skilled in the art Long-term indiscoverable recessive hazard factor, leading to these new blowers, there are biggish security risks.

More seriously, the generally existing defect having a single function of the new blower of the above-mentioned type only has air outer circulation Function not only aggravated the work load of new blower filter assemblies in the case where outside air serious haze, make its be easy Damage, and even it is not so good as indoor original air quality from external suction and by filtered air quality.In view of this, existing There is the new blower with interior circulatory function in technology there is also some relative coarseness, for example, some new blowers are interior in order to be formed Circulating working mode forms interior circulation pattern and outer circulation mode using two blowers respectively relatively independently, this is not only not gram The above-mentioned existing defect of existing new blower is taken, and causes new blower fan volume huger, structure is more complicated, and air duct is laid with more Add many and diverse.In addition, passing through there are also an indoor air inlet is directly opened up on some wall-hangings and cabinet type new blower indoors body The switching cover board of internal body selectively blocks indoor air inlet or connects the external air inlet of external intake stack, Lai Shixian The switching of outer circulation operating mode and interior circulating working mode, still, there is no change wall-hanging and cabinet type for this structure type The essence of new blower, the interior space is big, heavy, and the excessively high defect that consumes energy does not change, even more serious for intrinsic occupying It is this coarse way for directly opening up indoor air inlet in wall-hanging and on the indoor body of cabinet type new blower, will lead to and bang The major defects such as ring, filtration members damage, air endless loop.Specifically, due to the indoor host computer of wall-hanging and cabinet type new blower Inlet chamber is generally large, directly opens up indoor air inlet on host indoors, and indoor air inlet is closer apart from blower, through wind The room air of machine suction can be buffered unlike outside air inlet via external intake stack, directly enter the room host at a high speed Inlet chamber in, cause indoor body to tremble, even thunder, simultaneously because room air via blower powerful suction not High-speed impact filtration members through buffering, cause filtration members to be easily damaged, and can not play good filtration.Once filtration members are damaged Bad, filtration members can not effectively act as the effect of limitation air outlet velocity, and the flow velocity of air inlet and the outlet tends to be close, verifies, Easily form the endless loop of room air in the subrange around host indoors at this time, i.e. wall-hanging and cabinet type fresh air at this time The interior circulating working mode of machine can not effectively purify the air of a room substantially, be in invalid state.

The drawbacks described above of new blower has formed and has restricted the technical bottleneck that new blower further develops, some hazard factors Those skilled in the art are unaware that so far there are hidden trouble new blower specifically how is made to have both inside and outside circulation industrial On the basis of operation mode, it is effectively saved the interior space, working performance is well reliable, has become the technical problem of this field.

In preferred embodiment below, channel switching device of the invention is applied to a kind of with double working modes Airhandling equipment wall pipe in, wherein the advantages of channel switching device of the invention, will more specifically be shown.

As previously mentioned, occupying little space to realize double working modes, and compact integral structure, working performance is steadily reliable, The present invention provides a kind of novel air processing equipment, especially Two-way Cycles to embed wall hole formula airhandling equipment, at the air Reason equipment includes air hose and is exposed to indoor indoor body, as shown in figure 17.Particularly, the present invention is formed with outdoor in air hose Air pass through purification air hose internal channel and room air circulation Interior Space tracheae internal channel, from may be not present it is at random into Air hose, air-exhausting duct etc., complete machine structure is simple, compact, as shown in Figures 3 to 5.At this point, indoor body is equipped with the outlet of purification wind, room Interior air intake and air suction device 15.Wherein, air hose can be the common blast pipe of various airhandling equipment, but with In lower description taken in conjunction with the accompanying drawings, air hose is preferably the wall pipe being flush-mounted in wall hole.

Wherein, airhandling equipment further includes air duct switching device and air cleaning unit, and air duct switching device is for selecting Interior Space tracheae internal channel or purification air hose internal channel is uniquely connected to selecting property, so that airhandling equipment be made correspondingly to switch Work in interior circulating working mode or air inducing operating mode；That is:

Under interior circulating working mode, room air enters room from indoor air inlet under the effect of air suction device 15 Interior air hose internal channel is simultaneously expelled to interior from the outlet of purification wind after air cleaning unit purifies；

Under air inducing operating mode, outdoor air under the effect of air suction device 15 from the axially outer end of air hose (i.e. Fig. 1, Paper right end shown in Fig. 2, similar below) enter purification air hose internal channel and after air cleaning unit purifies from purification Wind outlet is expelled to interior.

After forming purification air hose internal channel and Interior Space tracheae internal channel in air hose, the circulation path of air-flow is longer, Even if under the strong pumping effect of air suction device 15, the air-flow also purification air hose internal channel or Interior Space in air hose Comfort cushioning is obtained in tracheae internal channel, it is small to the impact of complete machine, wall-penetrating type fixed peace is mainly reflected in generating impact It is small to the impact endurance test shock of complete machine in the air hose of dress.

In addition, the air suction device 15 in the embodiment of Fig. 1 is preferably single aerofoil fan, airhandling equipment The outlet of purification wind and aerofoil fan are axially aligned in the interior shaft end of air hose, this is because purification air hose internal channel and room air Pipe internal channel is integrated in air hose, and air stream outlet need to only be arranged single all in the interior shaft end of air hose in the interior shaft end of air hose A blower, and the two fans structure of unconventional Two-way Cycle airhandling equipment, in other words, blower can share, so that structure is integrated Degree is high.In addition, following will also address, since purification air hose internal channel and Interior Space tracheae internal channel compact Layout are in air hose Interior, air flow path is long, and air cleaning unit is also able to compact Layout.

For realize design compact-sized, path length in air hose and the purification air hose internal channel that can switch in due course and Interior Space tracheae internal channel, those skilled in the art are readily apparent that the shape using built-in double parallel pipe or more in air hose Formula, however this certainly will require the caliber of air hose big, can satisfy air quantity demand.For accomplish it is compact-sized and maximize increase into Air quantity, embedded wall hole formula airhandling equipment of the invention use including inner tube 1 and outer tube cannula structure, inner tube lumen and Any one of perimetrical lumen 6 between inner and outer pipes is purification air hose internal channel, i.e. outdoor air can be from the outer shaft of air hose End enters inner tube lumen or perimetrical lumen 6, then flows out from corresponding interior shaft end.

At this point, the other of inner tube lumen and perimetrical lumen 6 constitute Interior Space tracheae internal channel or at least constitute indoor A part of air hose internal channel.When due under double working modes, purifying the connection of air hose internal channel to enter outdoor air, room Interior air hose internal channel needs to close, and similarly, when Interior Space tracheae internal channel is connected to, purification air hose internal channel needs to close. At this point, in view of in the indoor air inlet setting under interior circulation pattern indoors body, thus relatively reasonable air duct arrangement Mode is can only to enter then to wrap to interior shaft end outflow from the interior shaft part of air hose.Therefore, Interior Space tracheae internal channel may include The inner tube lumen and perimetrical lumen 6 of inner tube 1, the room air that indoor air inlet enters is via inner tube lumen and perimetrical lumen 6 One of interior shaft end enter in air hose, then from axially outer end can enter another one it is intracavitary, preferably out of this another one Shaft end outflow.Not only process is longer in this way, but also under either interior circulation or air inducing operating mode, at least part is logical in air hose Road be room air and outdoor air share flow through place jointly, to also just facilitate the densification cloth of air cleaning unit It sets, needs be only arranged in shared runner.

On this basis, to realize Interior Space tracheae internal channel and purifying the in due course switching of air hose internal channel, from function It is divided in principle, air duct switching device should include two controllable switching valves, can open in due course to introduce outdoor air It citation damper and can open in due course to be connected to inner tube lumen and perimetrical lumen 6 (thus being constituted complete Interior Space tracheae internal channel) Communicating valve.Wherein, the axially outer end end face of purification air hose internal channel should be arranged in citation damper, purify air hose internal channel at this time Interior shaft end be connected to air suction device 15, with provide power suction air enter.Meanwhile in inner tube lumen and perimetrical lumen 6 Another one interior shaft end communication chamber in air intake, the axially outer end and perimetrical lumen 6 of inner tube lumen should be arranged in communicating valve Between axially outer end.
