In addition, in the end of a side of indoor set (from the front of indoor set in left end, bypass flow path 22 sides of the partition wall 46c that back will be narrated) be provided with for the scavenger fan unit 16 that room air is taken a breath, be provided with the electrostatic atomization apparatus 18 with the air-cleaning function that produces the static mist and purify the air of a room at the rear of scavenger fan unit 16.
In addition, Fig. 1 expresses the state after the body cover (not shown) that covers front panel 4 and main body 2 is removed, and Fig. 2 expresses the state that the electrostatic atomization apparatus 18 that will be housed in main body 2 inside for the link position of clear and definite indoor set main body 2 and electrostatic atomization apparatus 18 separates with main body 2.Electrostatic atomization apparatus 18 is actual is presented on the shape shown in Fig. 3,, as Fig. 1 or shown in Figure 4, is arranged on the left side of main body 2.
as shown in Figure 2 to 4, electrostatic atomization apparatus 18 from front suction inlet 2a and above suction inlet 2b via heat exchanger 6, be located at the bypass flow path 22 of heat exchanger 6 and indoor fan 8 bypass midway in indoor fan 8 grades and primary flow path 20 that blow-off outlet 10 is communicated with, upstream side in bypass flow path 22 is provided with high-tension transformer 24 and the bypass blowing fan 26 that becomes high-voltage power supply, be provided with electrostatically atomizing unit 30 and the silencing means 32 of the radiating part 28 with the heat radiation that promotes electrostatically atomizing unit 30 in the downstream of bypass flow path 22, and then in the downstream of silencing means 32, be provided with the static mist guiding parts 22d of the static mist guiding blow-off outlet 10 that will be produced by electrostatically atomizing unit 30 as the bypass discharge pipe.Therefore, under the state that has configured successively high-tension transformer 24, bypass blowing fan 26, radiating part 28, electrostatically atomizing unit 30 and silencing means 32 from upstream side, it is contained in the housing 34 of a part that forms bypass flow path 22.Like this, by being contained in housing 34, assembleability improves, and due at the interior formation stream of housing 34, so realize save space, and the air stream that bypass blowing fan 26 is produced contact reliably as high-tension transformer 24 and radiating part 28 polarity of heating part cooling, simultaneously, the static mist that produces from electrostatically atomizing unit 30 can be imported the blow-off outlet 10 of air conditioner reliably via static mist guiding parts 22d, can be with the static mist of generation to being emitted in air conditioning chamber.Particularly by static mist guiding parts 22d is set, thereby the setting position of electrostatically atomizing unit 30 is not restricted, and electrostatically atomizing unit 30 can be arranged at and hold easy-to-assemble position, thereby have advantages of that productivity and maintainability are improved.
In addition, housing 34 is according to the front from indoor set main body 2, make the direction mode parallel with respect to the direction of the air stream that flows through primary flow path 20 of the air stream that flows through housing 34 inside, longitudinally configuration, can, in the position disposed adjacent overlapping with scavenger fan unit 16, further save space from the front of indoor set main body 2 thus.
In addition, high-tension transformer 24 not necessarily will be housed in housing 34, but for the ventilation that utilizes bypass flow path carry out cooling, suppress temperature rise or save space this on the one hand, preferably be housed in housing 34.
, at this, with reference to Fig. 5 and Fig. 6, existing known electrostatically atomizing unit 30 is described.
As shown in Figure 5, electrostatically atomizing unit 30 by have radiating surface 36a be connected with cooling surface 36b a plurality of Peltier elements 36, the above-mentioned radiating part (for example radiator fan) 28 that is connected with the hot driving fit of radiating surface 36a ground, erect the sparking electrode 38 that is arranged at cooling surface 36b, comparative electrode 40 formations that separate the predetermined distance configuration with respect to this sparking electrode 38 via the hot driving fit of electrically insulating material (not shown) ground.
In addition, as shown in Figure 6, electrostatic atomization apparatus 18 has near the control part 42 (with reference to Fig. 1) that is disposed at scavenger fan unit 16, be electrically connected with Peltier driving power 44 and high-tension transformer 24 at this control part 42, Peltier element 36 and sparking electrode 38 are electrically connected to Peltier driving power 44 and high-tension transformer 24 respectively.
In addition, as electrostatically atomizing unit 30, in order making from sparking electrode 38 electrions, to produce the static mist, also comparative electrode 40 can not to be set.For example, if sparking electrode 38 is connected with a terminal of high voltage source, its another terminal is connected with framework, can discharge between the part of the close sparking electrode 38 of the structure that is connected to framework and sparking electrode 38.In this structure, the structure that this can be connected to framework is regarded comparative electrode 40 as.
In the electrostatically atomizing unit 30 of said structure, control Peltier driving powers 44 in Peltier element 36 during current flowing by control part 42, heat moves to radiating surface 36a from cooling surface 36b, because sparking electrode 38 temperature reduce on sparking electrode 38 dewfall.In addition, by control part 42, control high-tension transformer 24, while to the sparking electrode 38 that is attached with dew, applying high voltage, can electric discharge phenomena occur in dew and produce the static mist that particle diameter is nano-scale.In addition, in the present embodiment, owing to using negative high voltage power source as high-tension transformer 24, so static fog belt negative electricity.
in addition, in the present embodiment, as shown in Figure 7, primary flow path 20 is by the rear wall 46a of the stand 46 that forms main body 2, the two side of from the both ends of this rear wall 46a, forwards extending (only having expressed left side wall Fig. 7) 46b, the rear wall 48a of the rear guide part (air-supply guide part) 48 that forms below stand 46, two side (only expressing left side wall Fig. 7) 48b that forwards extends with the both ends from this rear wall 48a forms, form by a sidewall (left side wall) 46b of stand 46 and a sidewall (left side wall) 48b of rear guide part 48 the partition wall 46c that bypass flow path 22 is separated from primary flow path 20.And, form the bypass suction inlet 22a of bypass flow path 22 at sidewall 46b of stand 46, on the other hand, form the bypass blow-off outlet 22b of bypass flow path 22 at a sidewall 48b of rear guide part 48.
When air conditioner refrigeration, the relative humidity of the Cryogenic air of the heat exchanger 6 by indoor set is high, when in the situation that possess in electrostatic atomization apparatus 18 be used to the Peltier element 36 that keeps the skin wet, be easy to not only at the pin-shaped sparking electrode 38 of Peltier element 36 but also at whole Peltier element 36, produce dewfall.On the other hand, when air conditioner heats,, because the relative humidity of the high temperature air by heat exchanger 6 is low, therefore at the sparking electrode 38 of Peltier element 36, the possibility of dewfall does not occur very high.
Therefore, as above-mentioned formation, be located in bypass flow path 22 by the electrostatic atomization apparatus 18 that primary flow path 20 is separated by next door 46c with bypass flow path 22 and will produce the static mist, with obstructed over-heat-exchanger 6 and the air of polarity temperature and humidity regulation is not supplied with to electrostatic atomization apparatus 18.Thus, when refrigeration, effectively prevent from producing on the whole dewfall at the Peltier element 36 of electrostatically atomizing unit 30, security improves thus.In addition, when heating, can produce reliably the static mist.This point is also that the effect that static mist guiding parts 22d brings is set.Namely, if be made as the formation of offering the static mist discharge port of electrostatically atomizing unit 30 self at blow-off outlet 10, electrostatically atomizing unit 30 is positioned near blow-off outlet, easily be subject to the impact of the air of the air of low temperature or high temperature, but owing to having static mist guiding parts 22d, thereby electrostatically atomizing unit 30 self can be spaced apart from blow-off outlet 10, can get rid of the air of low temperature or high temperature air impact and the static mist stably occurs.
At this, if above-mentioned static mist guiding parts 22d is set, its advantage is large, but produces to the amount decay of the static mist of blow-off outlet 10 guiding, can not be efficiently to indoor shortcoming of emitting and so on.Namely, such as before record, the static mist that produces from electrostatically atomizing unit 30 due to by in static mist guiding parts 22d to by the indoor of air-conditioning, being emitted, so absorbed and decay by this static mist guiding parts 22d by this static mist guiding parts 22d the time.
The present invention has also eliminated such shortcoming, can be durable in practicality.Its formation below is described.
That is, static mist guiding parts 22d of the present invention is by the high material forming of insulating properties.The static mist is charged particle, and therefore, when static mist guiding parts 22d had electric conductivity, charged particle was absorbed and reduces.Therefore, preferred charged particle be the static mist guiding parts 22d that passes through of static mist by the high material forming of insulating properties, more specifically the preferred volume intrinsic resistance is 10
12More than Ω cm.Such as in the situation that use the material of the electric conductivity such as metal, the static mist is due to by static mist guiding parts 22d absorption, so it is significantly decayed.
In addition, charged particle be the static mist not only because of insulating properties, and sometimes because of the charged impact that brings of its stream, decay.Therefore, in the present invention, be made as the material of the impact of considering that also this is charged.
That is, above-mentioned static mist guiding parts 22d fastens by plastics and forms in productive pass, but common known plastic display case band electric array as shown in Figure 8.
Shown in Figure 8 is to make the material of easy positively charged to easy electronegative material sequence side by side with electric array, in other words, with electric array, refers to the sequence of easy ejected electron or the sequence of easy metal electron.In Fig. 8,, from the upper band electric array that represents in order PUR (polyurethane), POM (polyacetals), PC (Merlon), PA (polyamide), ABS (ABS resin), PS (polystyrene), PE (polyethylene), PP (polypropylene), PET (PETG), PVC (polyvinyl chloride), PVDF (Kynoar), be (easily ejected electron) material of the easy positively charged of material of top.In addition, the easy positively charged of common known ABS, PS is easily electronegative, in Fig. 8, between ABS-PS for easily being with respectively plus-minus electric border.
The static mist of this embodiment uses electronegative static mist.Therefore, by with easy positively charged materials'use in static mist guiding parts 22d, the decay that can alleviate the static mist.
Fig. 9 is by PC, ABS, PS shaping static mist guiding parts 22d and has measured the figure of the coal caving ratio of static mist.In addition, the 100%th, the static mist coal caving ratio while not using static mist guiding parts 22d, be the benchmark of the chart of Fig. 9.Learn according to its result, in the situation that used PC, ABS, coal caving ratio is more than 90%, slight fading, and on the other hand, in the situation that PS, coal caving ratio is below 20%, fierce decay.Therefore, the material of static mist guiding parts 22d preferably uses with the easy material of the band positive electricity more upper than ABS (in Fig. 8 material) more upper than ABS of electric array.
Particularly in the situation that use the induced air of the primary flow path 20 of automatic heat-exchanger 6 upstream sides to emit the static mist, wind speed in static mist guiding parts 22d reduces, and caliber is also less, and therefore, the material of static mist guiding parts 22d is large on the impact of static mist decay.In this embodiment, wind speed in static mist guiding parts 22d is below 0.5m/sec sometimes, in this case, the impact that the material of static mist guiding parts 22d brings is very large, preferably by the material of the positive electricity more upper than ABS of the charged sequence band take above-mentioned, particularly form as ABS, PA, PC, POM, PUR etc.
By emitting to primary flow path 20 in static mist guiding parts 22d and from the static mist that static mist guiding parts 22d is induced to primary flow path 20.In this primary flow path 20, because wind speed is high and stream is also wide, so be difficult to the impact of the material that is subject to forming.Therefore,, even formation primary flow path 20 and the rear guide part 48 of blow-off outlet 10, the material of rear wall parts 48a, sidewall 48b etc. are freely selected, also can make the minimizing of static mist lighter.Therefore, consider from the viewpoint of low decayization, by above-mentioned material, particularly good by shapings such as PC, ABS, but it is slight that the static mist of considering primary flow path 20 and blow-off outlet 10 reduces, also can be by height insulation and the cheap shapings such as PS, thus, can alleviate the static mist and reduce, and can be with low cost fabrication.
In addition, opposite in the situation that produce positively charged static mist, preferably use high insulation and PS and than the easy electronegative material of PS, particularly PS, PE, PP, PET, PVC, PVDF etc.
In addition, in this embodiment, to being released to indoor formation via blow-off outlet 10, the static mist is illustrated, but much less, can certainly be open at the suitable position of indoor set for making static mist guiding parts 22d, with its open-ended emitting from static mist guiding parts 22d.
Bypass suction inlet 22a between prefilter 5 and heat exchanger 6, namely be positioned at the downstream of prefilter 5 and the upstream side of heat exchanger 6, due to utilize prefilter 5 can effectively remove from front suction inlet 2a and above the dust that contains the air that sucks of suction inlet 2b, therefore can suppress dust and invade electrostatic atomization apparatus 18.Thus, can effectively prevent dust accretions at electrostatically atomizing unit 30, and release electrostatic mist stably.
In such embodiment, constitute the prefilter that doubles as electrostatic atomization apparatus 18 and primary flow path 20 with prefilter 5, only prefilter 5 is cleaned and safeguards just passablely thus, owing to not needing to carry out each other nursing, so can simplify maintenance.Further, in the air conditioner that possesses prefilter automatic cleaning device as described later, do not need prefilter 5 is safeguarded especially, thereby can realize non-maintaining.
On the one hand, bypass blow-off outlet 22b be positioned at heat exchanger 6 and indoor fan 8 downstream blow-off outlet 10 near, constitute from the static mist of bypass blow-off outlet 22b ejection and be full of whole room along with the air stream diffusion of primary flow path 20.Such bypass blow-off outlet 22b is configured in the downstream of heat exchanger 6, because if while being configured in the upstream side of heat exchanger 6,, because heat exchanger 6 is metal, as the major part (about more than 8～9 one-tenth) of the static mist of charged particle, can be absorbed into heat exchanger 6.In addition, bypass blow-off outlet 22b is configured in the downstream of indoor fan 8, because if while being configured in the upstream side of indoor fan 8, because can there be turbulent flow in the inside of indoor fan 8, the part (about about 5 one-tenth) of air static mist in the process with each position of indoor fan 8 bumps of the inside by indoor fan 8 can be absorbed.
In addition, primary flow path 20 sides at a sidewall 48b of the rear guide part 48 that is provided with bypass blow-off outlet 22b, by utilizing indoor fan 8 to make air stream have the speed of regulation, primary flow path 20 sides and bypass flow path 22 sides at sidewall 48b produce pressure reduction, make with respect to bypass flow path 22, primary flow path 20 1 sides become the negative pressure section of relatively low pressure, thereby from bypass flow path 22 to primary flow path, 20 attract air.Therefore, bypass blowing fan 26 can have low capacity, also bypass blowing fan 26 can be set according to circumstances.
In addition, static mist guiding parts 22d with the junction of two streams with primary flow path 20 (bypass blow-off outlet 22b) point to respect to the air stream in primary flow path 20 roughly the mode of the direction of quadrature be connected with partition wall 46c (the sidewall 48b of rear guide part 48).This is to produce the static mist because electrostatically atomizing unit 30 utilizes electric discharge phenomena as above, therefore must follow discharge sound, and discharge sound (discharge sound) has directive property.Therefore, locate in bypass flow path 22 and the junction of two streams (bypass blow-off outlet 22b) of primary flow path 20, do not make as far as possible discharge sound point to the people who is in indoor set the place ahead or oblique the place ahead by bypass flow path 22 being connected with front panel 4 almost parallel ground, can constituting, thereby reduced noise.
In addition, as shown in figure 10, static mist guiding parts 22d is connected with respect to partition wall 46c with the junction of two streams place of primary flow path 20 obliquely at it, when the mode of the air stream directed upstream side with respect in primary flow path 20 connects, has the effect that further reduces the noise that causes due to discharge sound.
In addition, even in the situation that the pointing direction of static mist guiding parts 22d points to the downstream direction of the air stream in primary flow path 20 and connects, its extended line is so long as not from blow-off outlet 10, to outside, stretching out, the discharge sound that produces directly passes from blow-off outlet 10 can be less to the amount of outside,, because the sound that directly enters user's ear is also less, therefore can obtain to reduce the effect of noise.
as mentioned above, owing to partition wall 46c, primary flow path 20 being separated with bypass flow path 22, the electrostatic atomization apparatus 18 that produces the static mist is arranged on the bypass flow path 22 that heat exchanger 6 bypass are communicated with primary flow path 20, thereby to electrostatic atomization apparatus 18, do not supply with and do not carry out by heat exchanger 6 air that humiture is adjusted, therefore can effectively prevent from, at the whole Peltier element 36 of electrostatically atomizing unit 30, dewfall occurs when refrigeration, improved security, and can produce reliably the static mist when the heating operation, can with the operation mode of air conditioner irrespectively, namely with irrespectively stably produce the static mist season.
Then, the air conditioner that also is provided with the prefilter automatic cleaning device is described, this prefilter automatic cleaning device has the suction device that attracts to be attached to the dust on prefilter 5 and remove.In reference Figure 11 the explanation scavenger fan unit 16, scavenger fan unit 16 is exclusively used in ventilation, but also can be used for suction device set in the indoor set with prefilter automatic cleaning device to the gas device.Scavenger fan unit 16 shown in Figure 11, in bypass flow path 22 sides of partition wall 46c were installed on the suction device 58 of prefilter automatic cleaning device, the prefilter automatic cleaning device was known technology in the past, therefore with reference to Figure 12, illustrated simply.Detailed construction and the method for operation of prefilter automatic cleaning device are not particularly limited to this.
As shown in figure 12, prefilter automatic cleaning device 50 possesses the attraction nozzle 52 that is free to slide along the surface of prefilter 5, attract the pair of guide rails 54 of the upper and lower side of nozzle 52 by being arranged on prefilter 5 to keep extremely narrow and small gap and move left and right glossily with prefilter 5, by attracting nozzle 52 to attract to be attached to the dust of prefilter 5 and with its removal.In addition, but attract nozzle 52 to be connected with an end of the suction tube 56 of free bend, the other end of suction tube 56 is connected with the suction device 58 that can change traffic attraction.Further, suction device 58 is connected with blast pipe 60, and to outdoor derivation.
In addition, be wound with around the above-below direction that attracts nozzle 52 along the band (not shown) that attracts nozzle 52 to be free to slide, at the face relative with prefilter 5 that attracts nozzle 52, be formed with the longitudinal length slot-shaped nozzle opening section about equally with prefilter 5, on the other hand, be formed with on tape 1/4 the slot-shaped attraction hole that length for example is the longitudinal length of prefilter 5.
The prefilter automatic cleaning device 50 of said structure cleans cleaning range A, B, C, the D of prefilter 5 as required successively, but when attracting cleaning range A, to attract hole to be fixed under the state of position of scope A at rotating band,, by attracting nozzle 52 to drive to left end from the right-hand member of prefilter 5, attract the scope A of the horizontal direction of cleaning prefilter 5 when attracting.
Then, rotating band will attract hole to be fixed on the position of scope B, and by attracting nozzle 52 to drive to right-hand member from the left end of prefilter 5 when attracting, the scope B of the horizontal direction of prefilter 5 is cleaned in current attraction in this state.Similarly, can attract to clean scope C, the D of prefilter 5.
The dust that passes through to attract nozzle 52 to attract that is attached to prefilter 5 is discharged to outdoor via suction tube 56, suction device 58 and blast pipe 60.
With further reference to Figure 11, suction path at suction device 58 is formed with peristome 62, and be provided with for the air door 64 that opens and closes this peristome 62, scavenger fan unit 16 is used as ventilation when air door 64 is opened peristome 62, when attracting cleaning, utilize air door 64 to close peristome 62, be used for attracting dust from the attraction hole of band.That is to say, can use same suction device 58 to realize attracting cleaning function and ventilatory.
In addition, do not express blast pipe 60 in Figure 11, blast pipe 60 is connected with the exhaust outlet 58a of suction device 58.
Figure 13 expresses the electrostatic atomization apparatus 18A with housing 34, and this electrostatic atomization apparatus 18A is arranged in indoor set main body 2 as shown in Figure 14 and Figure 15.With electrostatic atomization apparatus 18A be arranged on from the positive of indoor set or above see the position overlapping with scavenger fan unit 16, and make electrostatic atomization apparatus 18A be arranged on the peristome 62 of scavenger fan unit 16 and air door 64 near, thereby make it be disposed at the part that the air that attracted by scavenger fan unit 16 flows through.
Be described in further detail, the electrostatic atomization apparatus 18A one of Figure 13 is installed electrostatically atomizing unit 30 and the silencing means 32 with radiating part 28, electrostatically atomizing unit 30 parts except radiating part 28 and silencing means 32 are contained in separately housing (cell enclosure 66 and silencing means shell 68), and the end of static mist guiding parts 22d is connected and is communicated with the peristome 68a of silencing means shell 68, and the other end of static mist guiding parts 22d is connected and is communicated with primary flow path 20.In this case, that separate from primary flow path 20 by partition wall 46c and and the left surface of body cover between form and resettlement section 22e that dispose scavenger fan unit 16, electrostatic atomization apparatus 18A etc., become the parts that substitute described bypass suction line 22c and housing 34, and also accommodate static mist guiding parts 22d, as bypass flow path 22, form.
Thus, the air that sucks in main body 2 by prefilter 5 sucks resettlement section 22e from the bypass suction inlet 22a in the downstream of prefilter 5, when from front, seeing indoor set main body 2, the direction of this air stream flows abreast with respect to the direction of the air stream that flows through primary flow path 20 in the 22e of resettlement section.Can cooling heat dissipation section 28 by the air that flows in the 22e of resettlement section like this, and by the peristome (not shown) in cell enclosure 66 formation, enter electrostatically atomizing unit 30.
According to such structure, from the positive of indoor set or above see that the surrounding space of the scavenger fan unit 16 overlapping with scavenger fan unit 16 becomes bypass flow path 22, thereby can effectively utilize the resettlement section 22e of scavenger fan unit 16, electrostatic atomization apparatus 18A etc., realize saving space.In addition, for this structure, high-tension transformer 24 can be configured in any part in the resettlement section 22e of scavenger fan unit 16, electrostatic atomization apparatus 18A etc., and bypass blowing fan 26 can be set.
In addition, this bypass flow path 22, air stream forms with respect to the mode that the air stream by primary flow path 20 flows abreast when from front, seeing indoor set main body 2, can use the so simple structure of partition wall 46c with primary flow path 20 and bypass flow path 22 branches according to the mode of above describing in detail thus, therefore bypass flow path 22 can be easily formed, number of components can be reduced.
In addition,, according to this structure, can make the prefilter of electrostatic atomization apparatus 18A and the prefilter of primary flow path 20 share prefilter 5.
In addition, also can form opening 46d (with reference to Figure 11) near the bottom of the stand 46 at the rear portion that is positioned at scavenger fan unit 16, in order to draw the pipe arrangement (not shown) that connects indoor set and off-premises station.Above-mentioned bypass suction inlet 22a is an opening for the resettlement section 22e that forms with air intake resettlement section 22e and at partition wall 46c (stand sidewall 46b), outside by prefilter 5 and indoor set is communicated with, but the opening 46d that forms in the bottom of stand 46, the outside of resettlement section 22e and indoor set directly is communicated with, and becomes the opening that sucks surrounding air.In this case, resettlement section 22e becomes and makes the also bypass flow path of bypass of prefilter 5.Therefore, the air that is drawn into electrostatic atomization apparatus 18A flows into and does not pass through prefilter 5 from opening 46d, therefore also the prefilter that electrostatic atomization apparatus 18A uses can be set in addition as required.In addition, as long as in the structure that is formed with opening 46d, from the positive of indoor set or above, make electrostatic atomization apparatus 18A be arranged on the position this formation overlapping with scavenger fan unit 16 and do not change, just resettlement section 22e can be effectively utilized, space can be realized saving equally.
As mentioned above, because primary flow path 20 sides of bypass blow-off outlet 22b make air stream have the speed of regulation by indoor fan 8, thereby produce pressure reduction and become the negative pressure section that is attracted, even therefore bypass blowing fan 26 is not set, also can utilize the air cooling heat dissipation sections 28 by static mist guiding parts 22d 20 attractions from the resettlement section 22e as bypass flow path to primary flow path, will utilize the static mist that produces of electrostatically atomizing unit 30 attract primary flow path 20, and be discharged into indoor by air-conditioning.In addition, if near peristome 62 and air door 64, radiating part 28 is configured in the part that the air that is drawn into peristome 62 flows through, thereby also can is undertaken cooling by the air that is attracted by scavenger fan unit 16.
as mentioned above, according to said structure, owing to partition wall 46c, primary flow path 20 being separated with the resettlement section 22e that becomes bypass flow path, and the electrostatic atomization apparatus 18A that will produce the static mist is arranged in the 22e of resettlement section, and to electrostatic atomization apparatus 18A, do not supply with and do not carry out by heat exchanger 6 air that humiture is adjusted, therefore can effectively prevent from producing dewfall and improving security at the whole Peltier element 36 of electrostatically atomizing unit 30 when refrigeration, and can produce reliably the static mist when the heating operation, with the operation mode of air conditioner irrespectively, namely with irrespectively stably produce the static mist season.
