Description

Improve the low noise broad sense air-conditioning system of air filtration combination property significantly

The invention belongs to improvement to the broad sense air-conditioning system.The broad sense air-conditioning is meant except the various piece of the air-conditioning system of ordinary meaning, also comprise the room that installs an air-conditioner, the place, and the quilt of air-conditioning system is transferred object, as the room, building, the vehicles etc., air-conditioning system can be for industrial, commercial using, family expenses, office central air conditioner system or the simplest room air conditioner, and air conditioning system for automotive vehicles or the like.Central air conditioner system is divided into centralized again, and half is centralized, the distributing air-conditioning system.

Along with the use more and more widely of various air-conditioning systems, people are to promoting and the air filtering function of expanding air-conditioning system, reduce the secondary pollution of air-conditioning system, improve IAQ, reduce indoor dust stratification degree and reduce the air-conditioning noise more and more deep understanding, more and more stronger requirement have been arranged.This also becomes current air-conditioning in the nature of things and makes boundary, building circle, health circle, various circles of society's discussion topic more and more deeply concerned, more and more popular.

Study according to the parties concerned: respiratory system is the weakest organ pipe of human body defence, is subjected to various germs, the erosion of all contaminations the easiliest.People exempts from the hot rod bacterium as long as 10～50 of inspirations are exempted from the hot rod bacterium and will be fallen ill and eat into 100,000,000, and human body just can be infected, and both differ 2,000,000～10,000,000 times.(consult 2002 the 5th phases of " HVAC " magazine, Shen Jinming, " secondary pollution of air-conditioning system and the bacterial control " of Xu Zhonglin work) air conditioner or air-conditioning duct are inner dark unglazed, humidity is near 100% during refrigerating operaton, dust in air is as easy as rolling off a log accumulates gathering, become the assorted prolific hotbed of bacterium of disease, the a large amount of germs that produce can mix with air becomes the aerosol that carries disease germs, be dispersed into indoor, indoor air quality is seriously descended, become and cannot see, can not touch, all the time, immanent stealthy killer.This never is vertical tin an of alarming talk, air conditioner disease, and the uncomfortable disease of air-conditioning has been fast rise trend in China.Also must be pointed out, this contamination hazard more seriously with the passive protective physical fitness, the immunity that reduce people, be easy to flu, reduce physique, the form that the state etc. that makes human body be in inferior health is difficult for discovering exists in a large number, it is anti-that people's air defense is unequal to, and has no way out.Its potential social harm makes the national economy loss very huge.

The noise that produces together with air conditioner ventilation is the able-bodied stealthy killer of well-known harm people equally.

House dust is accumulated in addition, and particularly Winter-Spring sand season, the spring and summer intermittent drizzles in the rainy season time indoor several days of season will be gone up ash, go up mouldly, make us very helpless, and along with the increase of people's living space, upholster superior, complicated, this daily cleaning work is more apparent cumbersome and heavy.

Therefore, no matter from above-mentioned that on the one hand, the filtration cleaning of the air in dwelling house, building and all air-conditioning places being carried out low noise is not an inessential minor issue.Have the clean quiet dwelling house of low cost, universalness, clean quiet working environment has become affluence, thirsts for the basic demand the broad masses of the people that improve the quality of living aspect all.Clean quiet finger herein is clean, quiet.

Yet present situation is: the clean ability of the air filtration of our various air-conditioning and construction things, air-conditioner vehicle, and serious deficiency, or more originally do not have.Vast residential building just much less, be exactly those important buildings, comprise many office buildings, the commerce and trade building, the air filtering function of restaurant's mansion also is a deficiency very, very unreasonable, the air filtration precision of the air-conditioning system that those are local, generally should be for about European standard EN779 criteria for classification F7 level, (in the following article with the Direct Mark rank) consulted " clean quiet and air-conditioning technical " magazine fourth phase in 2002, table 1 and the continuous table 1 of Cai Jiezhu " air cleaner special topic lecture (continuous) ".But the air-conditioning unit in many buildings has does not simply use the air filtration core, and what have only uses the filter net sheet that does not have filtering accuracy together; Promptly use, the secondary air of many air-conditioning systems is crossed the meter heavy filtration precision of filter core and is also had only below 85%, is equivalent to the G2 level.What more make us the tear funeral is: many air-conditioning operators often take out the air filtration core in the air-conditioning unit need not, reason is that wherein main air is spent the filter core stage of replacement and had only about fortnight usually, how grey creep into dark during replacing again, carry out the narrow air conditioning box body inside that can't bear, really be inconvenient, uneconomical.The air filter that is used for the room air conditioner of vast residential building mostly is the filter net sheet that one deck does not have filtering accuracy.It is pointed out that external design at present, part adopts in the building of centralized central air-conditioning, beginning is installed thick plate type air of imitating and is crossed filter core and come the filtered air dust on the wall face at ventilating system air intake place, but not general.Also has lorry, car, the vehicles such as passenger vehicle travel on the highway that stirs up a cloud of dust, air filtration also is a big problem, many chauffeurs are in order to reduce dust, the have to outer gas air door of closing automobile air-conditioning, gas circulates and carries out air-treatment in relying on, and stands the interior air of abominable car that no new wind replenishes.

Can so why, these situations appear for a long time? at first this is because existing various air-conditioning systems, the air-conditioning unit, air conditioner is subjected to machine overall dimension and structural limitations, be subjected to the filtering material performance limitations, be difficult to make in the air filtration, by filtering accuracy, filtration resistance, dust containing capacity and this group of filtration cost are crucial and conflicting, the raising of the free broken property of the synthetic filter performance indications that the index of mutual restriction constitutes.This will mention my three patent applications from submission in 2002, and the scheme of wherein mentioning can be used for improving extremely effectively the air filtration integrated performance index of various broad sense air-conditioning systems.

I have proposed a kind of organization plan of air conditioner in No. 02238820.6 utility model patent of ZL " the horizontally disposed multi-layer air filter of filtering surface ": it is characterized in that air filtration face wherein is horizontally disposed with.Thereby can improve its air filtration front face area very significantly, and effectively improve the area utilization of air conditioner, volume utilization reduces running noises.

I propose to use a kind of compound nonwoven air filting material in No. 02238819.2 utility application of ZL " intermediate effcient that dust containing capacity increases considerably and high-efficiency air filtering core and filter paper "; The windward side of this material is one deck manmade dust meter heavy filtration precision less than 60% fiber loft layer.The advantage of this composite air filtering material is that dust containing capacity is big, long service life, and filtering accuracy can be from G3 more than H14.

The excessive problem of filter material thickness that the air filter material that I propose at No. 022388192 utility model patent of ZL in No. 2004100030982 applications for a patent for invention " the high slim compound nonwoven air filter material of dirt and method for making and the relevant air filtration core of holding " exists has carried out further improving improving.

Through being 55% to a kind of superficial layer meter heavy filtration precision, bottom is the actual measurement of imitating the compound nonwoven air filting material of nonwoven material layer in one deck, has verified that the synthetic filter performance of these two kinds of composite air filter materials has breakthrough leap to improve really.Its data are as follows: grammes per square metre: 440g/m ², price is less than 30 yuan/m ²During filtration velocity 1m/s, its inceptive filtering resistance is 75Pa, and when whole resistance was 188Pa, the manmade dust dust containing capacity was 1362g, the heavy precision of manmade dust meter is 92%, please note: its dust containing capacity index is shockingly high, surpasses more than 120% of similar nonwoven air filting material, and its performance indications collocation, its synthetic filter performance is extremely excellent, and this belongs to the breakthrough raising to existing nonwoven filtering material performance undoubtedly; Consult Tongji University's heating ventilation and air conditioning laboratory " test report " TJ2002-07-30 number, this composite filter material can have multiple variety type, its air filtration precision can be thick effect, the middle effect, in efficient, efficiently, below it is called especially compound nonwoven air filting material of high dust containing capacity and the compound nonwoven air filting material of slim high dust containing capacity.

The purpose of invention: adopt value analysis, the method of system engineering, comprehensive consideration comprises building, the vehicles etc. are transferred the airfiltering process of broad sense air-conditioning system and the performance of object, to improve the raising IAQ is purpose with getting twice the result with half the effort, comprehensive adopt the technical scheme that comprises above-mentioned two patent applications the whole bag of tricks, the relative section of broad sense air-conditioning system is carried out necessary improvement.

Attention: " good " in getting twice the result with half the effort comprises that volume is small and exquisite, reduces noise, and easy to use and good looking appearance etc. are main to reduce noise again.Because noise and air conditioner ventilation, comprise that air filtration is inseparable, noise belong to one of IAQ subsidiary but be important index, this has a lot of arguments, noise is the same with air quality to belong to the hard nut to crack that air-conditioning system is difficult to overcome." Shenzhen office building indoor air quality subjective assessment and the correlation analysis " that will mention below consulting.

Total inventive method: under the situation of crossing filter core of the air filter that as far as possible adopts the general single-stage that reaches the compound nonwoven air filting material making of slim high dust containing capacity simplification, air filtration core display is moved away by the place ahead distortion of the surface of the surface cooler in the air conditioner, horizontal plane and other face upwards that move to goes, and moves to self getting on of various buildings or automobile.

Illustrate: this moving is actually extension from the prerequisite of the structure of simplifying filter to building that the front end face of air conditioner has been carried out not having any how much restrictions under.Its basic point of departure is with the transsexual energy of volume: ventilate with volume and filter this moving of combination property (comprising performances such as energy-conservation, noise reduction) and mean also that air-conditioning system and building are got in touch more closely and integrated.The filter core number of air filtration core display is the integer more than or equal to 1.

B, adopt airduct or fixed or movable tuyere, the air port (29) of loosing is guided the air inlet that be installed in indoor apparatus of air conditioner (30) in room or room (28) or air outlet near by minor diameter wind hole (27) new wind or guide the central core position of room or room into;

C, in each room or room (28), as far as possible away from the place in indoor set or tuyere, the air port (29) of loosing, be provided for discharging transom window, the air gap of the fixing or c /v area of air, air guided into the middle house (being generally hallway in an old Chinese house, passageway) of each standard width of a room in an old-style house;

D, between the back shotgun house of dwelling house or suite (24) or the lavatory (32) of central longitudinal depths, exhaust fan or the smoke exhaust ventilator (34) establishing exhausting window in the kitchen (33) or have the free exhaust function, the air of the basic air quantity that will advertise from mini fan (26) is finally discharged a whole set of dwelling house or suite (24), or offers adjustable exhaust apertures or blast pipe towards the external world in each room;

E, each air conditioner (30) can adopt existing various air conditioner; Or the underflow type air conditioner (30) that adopts described meta of claim 7 or low level to install so as to form efficiently in relevant room, displaced type air-conditioning air-flow clean, low noise;

F, comprise that the housing or the sound insulation casing (53) of the electrically ventilating device (57) of air conditioner (30), Rose Box (37), secondary blower fan (52), outdoor machine of air-conditioner can adopt the good wall body building material manufacturing of sound insulation, can fuse with body of wall, the floor of building, form incorporate overall structure.

Dwelling house or inner room (24) also can be the industry and commerce room.What needs one were carried is corridor formula building, and as a big suite can be regarded whole one deck building in the middle corridor type house of particularly seeing in the curtain buildings more, also can regard a certain house of side, corridor as a little suite, and all depend on the circumstances.

The general air filtering box (37) that is provided with mini fan (26) and air filtration core (6) that relies on of this dwelling house is blown, and also air filtration core (6) can be shifted out, and the window or the wall that are seated on these areas get on; This kind window can be installed rainproof shutter in the outside of this air filtration core (6) or have the window of air inlet in glass or window frame side, forms the double window structure.Make (37) become simple wind pushing box (37).Wind pushing box (37) can adopt special for or commercially available the quiet machine that send of FV-12NSIC type.(this is a kind of expansion to its application)

Illustrate: accompanying drawing 7 is the building floor map with accompanying drawing 8.In the drawings: represent ventilation window or ventilating fan or smoke exhaust ventilator (34) with triangle, represent tuyere or diffusing air port (29) with little garden circle, represent indoor apparatus of air conditioner (30) with little rectangle, represent mini fan (26) with little square, short-term is represented minor diameter wind hole (27), and two circles represent that overfire air fan (52) straight line represents tube connector.The building of this form is applicable to the less buildings of the density of population such as various urban and rural housings building, villa, hotel, office building, commercial building, some factory building.For some high-end residential building, every cover house has tier building, at this moment can regard each layer house as a cover main residence, and the width of general every cover dwelling house is one to four standard width of a room in an old-style house or wideer, and every standard width of a room in an old-style house has two from front to back to the three rooms room.The width in room can be equally wide before and after the every standard width of a room in an old-style house, also more have different wide, the mid portion of every standard width of a room in an old-style house fore-and-aft direction, be generally the room or have a hearing, the passageway, also popular big room from the front to the back now, as L type room etc., pattern is varied.Mini fan (26) is generally slow-speed of revolution centrifugal fan per minute 500～3000 to be changeed, and the blast pressure head is bigger like this, and noise is also less.

When using mini fan or pressure fan, because blast is too little, the diameter of ventilation duct needs big slightly.Say the basic air quantity of mini fan in the literary composition, the main residence of every cover or the suite that are meant generally have only 1～3 people, maximum 5 people, and according to the air conditioner ventilation standard, everyone only needs 15～30m ²/ h or bigger newer wind air quantity, that is to say: every house only needs 40m ²New wind air quantity about/h, as long as every cover dwelling house is 60～200m ²The new wind air quantity of/h is just enough, Here it is mini fan and every needed basic air quantity in room.(offices etc. are industrial and commercial to need more air quantity with the room)

During with many mini fans, the air quantity of every typhoon machine also will lack.

In this case, the power of the air quantity of mini fan (26) is very little, can be with various speed regulating methods commonly used; With time during control circuit, not only can control average air quantity, can also make its gauge tap time, suitable multiple different situation.Because power of fan is little, its cost also can be very cheap.

Minor diameter wind hole (27) is used to connect mini fan (26) and tuyere or diffusing air port (29), also can be used for the circulation of air of adjacent room area, should note its decorate properties, and suitable draught area.Because air quantity is less, between (27) and (29) except directly be connected with obvious the connection, can be by being positioned at wall, the hidden pipe connection under the ceiling.

Because air quantity is less, the pipeline that needs, valve, diameter will be very little.Flow in the room, resistance is also little, thereby as long as the blast head of blower fan is tens to Pa more than 100 just enough, thereby the rotating speed of blower fan can be obtained low, can adopt four utmost points, sextupole even ends of the earth motor, and like this, the work noise of blower fan may be very little.

Facts have proved: the employing rotating speed is 1500 rev/mins a little air quantity centrifugal exhausting fan blower fan, its noise can be reduced to about 30 decibels, and, noise mostly is high-frequency noise, if again in motor, fan blade, air channel, the utilization of inhaling the material of making an uproar cooperates works hard, and reduces its rotating speed as far as possible, noise can be dropped to 20～25 decibels, a kind of per minute 180m is for example arranged ³The pressure fan of flow, noise are 23 decibels, and this is very low, moreover, can also adopt the comprehensive Noise Reduction measure to reduce noise.The air filtering box (37) of mini fan can be installed again with sound-absorbing materials such as foam rubbers; Can adopt silico-calcium magnesium plate, thick sheet metal or their composite board and combined plate are made its housing, can also carry out continuous perforation on blower fan fin or Fan casing and cut down the air blast noise.Can adopt soft sound absorption airduct to connect air filtering box (37) and minor diameter wind hole (27), and it is obtained longer as far as possible, thereby make noise attentuation more more.

Fabric structure of the present invention in addition can also be arranged mini fan (26) on balcony, on the window that wafts or exterior wall is outer or staircase in, shut room noise behind the door and window and will further be reduced to inappreciable stage below 20 decibels.

Can certainly be located at indoorly, locate, be located at indoor mini fan (26) as window medial surface etc., can be simply with the bag type filtering core retainer plate on discharge pipe, remove air filtration casing (37) from.But, must pay special attention to prevent the noise measure.For example, can adopt the way that the sound insulation plenum chamber is set.At this time, and implement this kind scheme whenever all should note device of the present invention should with the house inside and outside decorate and cooperate, strengthen performance attractive in appearance.

Because basic air quantity is little, the area of crossing the filter core filtering material that needs can be obtained very little, thereby can make single pocket type, is enclosed within on the air outlet of gentle breeze machine (26), or is positioned at the front end of this Rose Box (37).Thereby make air filtering box (37) also can do very for a short time, very cheap, be easy to be provided with arrangement.

Owing to can adopt the good high dust containing capacity of synthetic filter performance or the composite air filtering material of slim high dust containing capacity to do filtering material, this air filtering box (37) only needs single-stage to filter, and just can reach the desirable filter effect of F5～F8.

Suppose that single bag type filtering core that we make is of a size of the tiny pocket of φ 80mm * 300mm, its filtering material area is about 0.13m ²Make filtering material as the material that still adopts the front to detect, when basic air quantity is 80m ³/ hour, its filtration velocity is about 0.16 meter per second, filters initial resistance and is about 10Pa, and is quite desirable.And the leeway of improving this filtering accuracy is arranged.And 0.13m ²The filter material area be very little, for the underflow type air conditioner that air filtering box of the present invention (37) and back will be narrated, the filter material area is significantly expanded, be easy to do.

Guide the new wind of trace the air inlet or the air outlet of indoor apparatus of air conditioner into, can utilize the powerful air quantity of air conditioner, carrying disperses the everywhere area of new wind to the room.

The central core part in room refers to people often movable zone in the room, and generally at the house central part, height is in 0.4～1.8 meter zone.

The tuyere of the activity outlet by similar sedan air conditioner, the air port of loosing, can save tuyere near indoor apparatus of air conditioner or the airduct at core position, house, make indoor succinctly attractive in appearancely, movable tuyere can make new wind throughput direction grasp flexibly according to actual conditions, actual needs.In fact this is a kind of high performance calm residence independent ventilation system that keeps a grip on.It is the displaced type ventilating system of a kind of basic air quantity or minimum air quantity.Be a kind of " minor diameter heat-exchange system " that is different from PANASONIC, be different from the mechanical supply and exhaust mode in no air channel of " the Airflow air exchange system " of Mitsubishi Electric Corporation.

Adopt the air port of loosing, air outlet is uniformly dispersed, help spreading to the house each several part, in the accompanying drawing 5, diffusing air port or tuyere can be positioned at the high position of about 1 people, both can can adapt to various situation needs towards the central core position air-supply in room again towards the air inlet or the air outlet air-supply of indoor set.Air outlet also can be made motor-driven regulation and control type, comprehensively grasps with aforesaid electronic control circuit.

Air draft transom window, air gap, the position that is arranged in room and the room (28) away from the air port of loosing is in order to make new general mood stream streamline length as best one can under the prerequisite at central core position, room of flowing through, to make new wind effect performance better.

The new wind that enters dwelling house is finally through the central hallway in an old Chinese house of complete dwelling house or suite etc., and it is outdoor to wait lavatory, the kitchen at place to discharge by back row, makes the front wind circulation of new distinguished and admirable line by dwelling house or suite (24), up to the back.Perhaps enter the hallway in an old Chinese house, passageway by staircase, through the room around them, flow to outside window or balcony, make new distinguished and admirable line reach the longest, make new wind effectiveness perform to best, new wind has obtained the use of the orderly repetition of polyphone.

For example, the general household's number of present dwelling house only has about 3 people, wherein the people of living, in front-seat room, no doubt breathed new wind, if they have arrived again between back shotgun house, because front-seat room nobody or minimizing people, in the back, they still can breathe new wind.The Jue Daduoshuo personnel clock time in a measure of only walking about wherein can not have a significant effect to the air freshness in each room.

Like this, flowing into indoor new wind has obtained reasonably, has used fully.Sending indoor new wind to, both enough use, is not again unnecessary too many, and certain surplus is arranged, the foundation of calculating that Here it is, design, control air quantity.

Resh air requirement was both enough, and inexcessive again significant advantage has:

A, can save the idle call electric weight.For example: the basic air quantity of every room or room (28) is 40m ³/ h.When the air-conditioning temperature difference was 8 ℃, the sensible heat power of its cooling air only had about 100W, is equivalent to the electric power of 30W.Only be equivalent to about 0.5m ²The needed refrigeration work consumption in area room.Can bear fully, as long as improve a bit a little on the heat-insulating property in house, the house window area reduces a bit a little, or to window sunshade a little, this wasted power just can be retrieved.In this case, can not use loaded down with trivial details and the exhaust sensible heat heat reclaim unit of obvious noise is arranged.This is than opening window seam, introduces new wind for well.Seam is not easy to control air quantity because window, and air intake and air-out have the air-flow short circuit phenomenon, needs the newer wind of volume just can satisfy the demand.It is much reasonable, much energy-conservation that air-flow of the present invention definitely draws new wind than the seam of windowing.

B, can introduce new wind throughout the year, if introduce new wind with the miniature new blower fan of commercially available indoor apparatus of air conditioner inside, the one, noise is big, and the 2nd, can only when opening, use by air-conditioning, can not use at ordinary times, the inventive method does not then have this restriction.

C, be not only when energy-conservation, can not introduce unnecessary excessive new wind more, for prevent empty in dust, prevent that the dirt mite from growing, also to control excessive new wind.

After the air in d, front-seat room flows to the room, back, still have surplus cold or waste heat, realized the secondary utilization of used heat, useless cold, useless wet energy, in fact, the air-conditioner temperature in room, back requires not have front-seat room and requires height.Enjoy the cool if be aided with fan again, the air conditioning function between back shotgun house still is pretty good.The situation of the air flow ambient room in the hallway in an old Chinese house is also similar.

E, existing building, the air intake of windowing, this air quantity can not be controlled fully, may blow into ten times of indoor resh air requirements, the hundred times of ground requirement that is above standard.So also disagreeable dust will be brought into indoorly, in rocky season, even at ordinary times, each room is crossed a couple of days even all can be amassed many dusts every day.

Current people's living standard improves, and average living space constantly enlarges, and carries out complicated fitting-ups again more, and what be afraid of most is exactly the indoor ash of going up, and has no time often to sweep.Simultaneously, the indoor ash of going up grows germ and also causes various diseases or sub-health states such as cold cough easily.

The comprehensive clean ventilatory of this building of present embodiment belongs to the improvement to the mechanical air supply air draft mode in no air channel.(China Machine Press publishes, Jiang Nengzhao, Zhang Hua chief editor's " residential central air conditioning practical technique " 13.5.2 joint and 13.5.3 joint), be a kind of mechanical air supply mode or independent ventilation mode (DOAS) that adapts to the clean no air channel of novel energy-conserving of China's actual conditions.

Its improvement has following aspect:

A, new wind flow circuit reach the longest path line, and new wind obtains series connection and uses, and also make and use the quantity of blower fan to be reduced to minimum.

B, the new wind flow of control are bare flow, not many not very little yet.

C, employing mini fan, the filter type that nearly body is advertised or aspirated.

D, the air filtration core that adopts G3 to make to the compound nonwoven air filting material of the general or slim high dust containing capacity of F7 level carry out single-stage air filtration, do not need complicated two-stage air filtration.

E, mini fan is arranged in places such as balcony, staircase, can overcome influences an exterior wall difficult problem attractive in appearance.

F, greatly reduce the air-supply noise of the house hall, might reach the following similar absolute quiet degree of 20dB (A) even 10dB (A).

G, this scheme have kept all door and windows in the design of existing building thing fully, can not limit opening of door and window.What require only is that the sealing of window is better.Can open door and window in case of necessity, close mini fan (26), freely switch to original natural ventilation system.

In fact h, this draft type belong to a kind of dedicated outdoor air system (DOAS system) of suitable China's actual conditions, the DOAS system (consulting the HVAC magazine on 2003 the 6th phases, " dedicated outdoor air system (DOAS) research " that Yin Ping, stanley A.Mumma are shown) that a kind of strainability is extremely excellent.In recent years, the basic fundamental of America and Europe's in fashion DOAS system has 3: cold air distribution dedicated outdoor air system, the cold furred ceiling of radiation, new wind total-heat exchanger.And the characteristics of draft type of the present invention are long-life, single-stage air filtration efficiently, the low-noise electric ventilation unit that does not have polyphone air supply mode, second difference force feed wind mode and the whole building structure of sending airduct back to and underflow displaced type air conditioner (30) or the like.

The major advantage of the described air-conditioning and construction thing of present embodiment may be summarized to be:

Clean quiet ventilation, the many usefulness of a wind, without airduct, the noise spy is low;

The four seasons ventilate, and switch freedom, save the energy, and are cheap.

Cheap, pointed out its good economic, its performance is:

A, filter the cheap of ventilating system itself.

B, be applicable to and the house dwelling house of all forms do not resemble the ventilation by pipes system, need increase the ceiling interlayer, carry out complicated finishing, these are expensive especially, may account for 10～15% of house total price, 15～30% of finishing total price.That is to say that every square metre of dwelling house may be saved 400～2000 yuan or more.

C, do not have bulky complex, the ajutage of expense costliness and backwind tube system have greatly reduced air-conditioning system and have grown germ, the danger of secondary pollution.

D, be specially adapted to one of frequency conversion or not frequency conversion and drag cold neck and the room air conditioner in bulk of hanging of many domestic air-conditioning systems, radiation.

Frequency conversion one drags many advantages a lot, and shortcoming has two: the one, and the cost height, the 2nd, be not easy to set up ventilating system.Along with improving its price, output reduces now; Add the improvement feature of present embodiment building, set up ventilating system to become very convenient, be dirt cheap, thereby the present invention will be very favourable to promoting and developing the frequency conversion multi-split air conditioner.Same displacement ventilation system of the present invention is also extremely beneficial to the additional new wind problem that solves displaced type air-conditioning system, the cold furred ceiling of radiation or room air conditioner general in bulk.

Can also improve the electrical equipment control device of this air-conditioning system, make it can be to the described tuyere of this facility, wind valve system carries out unified control, further improves the automaticity of this air-conditioning system.

Adopt air conditioner ventilation form of the present invention, and do not mean that the optimal design that to abandon the electrical control part of air-conditioning system, on the contrary, breakthrough raising along with the performance of ventilating of various air-conditionings, optimize automatically controlled design and become more important, must not make it become the restraining factors that overall performance improves by a larger margin.

For the humidity of controlling new wind is not too high, when high humidity, can carry out dehumidifier to new wind and handle, its method can adopt in air filtering box or additional independently surface cooling or rotary-type or liquid-type dehumidifier apparatus on the differential pressure balcony.

Because it is very little to control the new wind flow that enters every cover dwelling house and each room, thereby the dehumidifier load can be not too many yet, per hour is approximately the moisture-exhausting amount of hundreds of grams.

Embodiment shown in the accompanying drawing 8 is to the explanation of differential pressure balcony, it is characterized in that:

A, balcony (25) are for being equipped with dark or the glass of reflected infrared ray rete or the enclosed balcony of external sunshade device;

B, with air filtering box (37) or mini fan (26) by air inlet (36) be located at window or exterior wall on the outdoor new wind of air filtration core (6) inspiration, flow to enclosed balcony (25) or closed cells (35), make them become the differential pressure space, thereby order about clean new wind and flow to each standard width of a room in an old-style house first row or a last sweep or room (28), begin the flow process that it uses in the series connection of a series of rooms by the minor diameter wind hole (27) that is positioned on the balcony (25).

Illustrate: this is actually has made an air filtering box with the integral body of balcony (25) or closed cells (35).

Its benefit is that balcony is in closed state, and air wherein is the filtration pure air, thereby becomes the clean balcony that is not easy ash, improved use value, and when cold day, sunlight is injected balcony by glass, can improve temperature, is equivalent to energy-conservation solar energy housing.

Its shortcoming also is because sunlight incident can elevate the temperature during hot day, causes that flowing to indoor new wind-warm syndrome spends height, is unfavorable for air conditioner energy saving.

Here it is adopts the glass or the sunshade setting of dark color or reflected infrared ray, perhaps adopts the reason of closed cells (35).When adopting air filtering box (37), balcony (25) or closed cells (35) become the malleation cell, they become negative pressure space when employing is arranged on the window of balcony (25) or closed cells (35) or air filtration core (6) on the exterior wall and wind pushing box (37), general designation differential pressure space.

The differential pressure balcony also has a benefit, and independent dehumidifier apparatus can be installed: after adopting independent surface cooler or rotary-type dehumidifier or liquid dehumidifier apparatus that the fresh air dehumidifier on the balcony is handled, send into premises.

Looking back aforesaid filtration cell (23) inside also is negative pressure state, and independent dehumidifier apparatus also can be installed in its inside.Both structures, principle have many similarities.

Flexibly how accompanying drawing (7) illustrated embodiment owing to adopted air filtering box (37), just, can be pulled on window in winter, allows balcony absorb sunlight heat energy, heats new wind.And in summer, can open the window from the new wind of extraneous inspiration normal temperature, also the inlet scoop of air filtering box (37) may be arranged near the on balcony special new air regulator hole the extraneous new wind of inspiration, for avoiding the balcony hot blast to sneak into, can establish some baffle plate guiding devices and deaden.Air filtering box (37) is placed on the platform of the window top of wafing, is equivalent to its (37) are placed on the situation of windowless balcony.

Mention above: can make the differential pressure space to enclosed balcony (25) or sound insulation closed cells (35) or filtration cell (23) etc.Be positioned in its tangible above-mentioned dwelling house or the suite (24) on all areas on the circuit that ventilates of contacting, all exist the air pressure that successively decreases, this air pressure is to form the power that polyphone ventilates.

But the room of working as this dwelling house or suite (24) is more, the cover type big complicated or its have two-layer or two-layer above inside space or other room that does not meet perfect condition when arranging situation, only rely on the power that is positioned at its peripheral air filtering box (37), just want all rooms to a whole set of dwelling house, all areas realizations gravity flow polyphone ventilation uniformly (comprising the mixed connection ventilation) will be compared difficulty or unreasonable.Can adopt two-stage differential pressure draft type to address this problem for this reason.

The dwelling house of two-stage differential pressure draft type of the present invention or suite (24) are characterised in that:

A, on be positioned at the external wall (21) of each standard width of a room in an old-style house front or back or one or more air filtering box of being provided with of outside, roof or balcony (25) or staircase and corridor or wind pushing box (37) directly or by differential pressure balcony (25) advertise through the clean new wind that filters and form the polyphone ventilation on portion's part area within it to dwelling house or suite (24) inside; Make this part area become the secondary environment space of air cleaning;

B, only rely on air filtering box or wind pushing box (37) still to be not enough to form enough abundances from secondary environment space to one or more, the inside space pressure air blowing of enough uniformly new general mood stream or take out and draw air draught and make these inside spaces form secondary differential pressures air-supply zone with one or more secondary blower fan (52) with basic air quantity and low noise characteristic; Wherein secondary blower fan (52) can have the air filter that belongs to himself;

C, each secondary blower fan (52) can and connect, polyphone, and the mixed connection mode is to one to multiple room or room's forced draft or negative pressure induced wind;

D, the air-supply of secondary differential pressure or air inducing zone have necessary hermetically-sealed construction with respect to secondary environment space, and air gateway and corresponding valve air valve adjusting device;

E, secondary differential pressure zone can be to the room that comprises wherein, the lavatory, and the study, balcony, the secondary environment exhaust that corridor etc. are located or directly to extraneous exhaust, or simultaneously to two kinds of environment exhausts.

Illustrate: because the air filtering box (37) of the high dust containing capacity nonwoven of employing single-stage air filting material or air filtration core (6) are as previously mentioned, can have the clean performance of very high air filtration, thereby will be than the clean more ash that lacks of external environment by the secondary environment space of its air feed, thereby secondary blower fan (52) can attach filter, also therefore can adopt the suction mode.Have only when secondary environment can produce the unacceptable dust that is produced by himself, or secondary differential pressure zone is when needing cleaner air, secondary blower fan (52) can be set up the air filter that belongs to himself.

For large-scale middle corridor type tier building, particularly the industry and commerce building should notice that its basic air quantity is very big, at this moment middle corridor can be designed to secondary environmental area, can adopt ventilation shaft to provide new wind to the middle corridor of each floor.The filtration of new wind can be concentrated at ventilation shaft and be carried out, and also can carry out at each floor, and the ventilation feature of this industrial and commercial building is no airduct, does not particularly have ajutage.In curtain wall formula building, often need to discharge outmoded air from middle corridor, at this moment can utilize the smallpox interlayer of middle corridor or the blast pipe in this interlayer to carry out exhaust.

Because be mounted in the inside of dwelling house or suite, secondary blower fan (52) should be specifically noted that noise reduction, sound insulation, and biography is reduced to the noise intensity in the room of keys such as bedroom, core as far as possible.

Secondary differential pressure zone generally belongs to core rooms such as bedroom, living room, and indoor apparatus of air conditioner (30) wherein must be installed, and is called for short air conditioner (30) below.The air of regulating through humiture is discharged to secondary environmental area by this zone, is actually a kind of secondary utilization to this airborne sensible heat and latent heat, belongs to a kind of very effective very significant air conditioner energy saving mode.And the less characteristics of the member of Modern Family also make the secondary utilization of this Air Conditioning, can not cause or seldom cause the new wind deficiency in indoor some zone.The valve air valve is regulated, and can adopt the structure of sliding window and so on.

The study homalographic both can be arranged in secondary environmental area, also can be arranged in second difference nip territory, and all are on concrete condition, specifically need to decide; If be arranged in second difference nip territory, can be located at the downstream position of the air-flow in certain bedroom.

When every cover dwelling house area has two-layer above area, can on every aspect is long-pending, all arrange secondary environmental area and second difference nip territory.

How to cooperate architectural design, the decoration design of dwelling house, divide secondary environmental area and second difference nip territory, reach two aeroseal and airflow between the area, this belongs to general engineering design problem.

Can adopt Fig. 7 that secondary differential pressure zone is illustrated.Drawn two circles are just represented an overfire air fan (52) in the middle hall of Fig. 7.The pure air that its is understood in the middle Room that will belong to secondary environment is advertised the into cubicle of back.At this moment this cubicle has just become second difference nip territory.Need explanation, second difference nip territory generally will substantially exceed the area in a room, only is to say something here.Among Fig. 7,, drawn mini fan (26) etc., only to choose one or the other of these two also in the back in this bedroom.

Problem as for the reduction noise:

Purpose of the present invention is exactly to improve air quality comprising that building from interior broad sense air-conditioning system, adopts the method for value engineering, system engineering with getting twice the result with half the effort, the good good looking appearance that just comprises wherein, and noise reduces.

And the total method of the present invention, exactly the air filtration core is moved on to self getting on of building outside the surface cooler surface, this volume that is actually air-conditioning system has carried out great expansion, makes in sizable area of whole building and the air-conditioning system that volume all is included in broad sense to go.Especially modern people's housing condition is improved, and the living space expansion provides incomparable wide space for this true extension especially.

Hai Kuo is with fish dive, it high bird flies, for air-conditioning system, embody in the present embodiment, comprise air filtering box (37), secondary blower fan (52) and air-conditioning (indoor) machine (30), can also comprise the volume of air-conditioner outdoor unit can seldom scruple ground (must be certainly rational, necessary, as far as possible less) expand arbitrarily, its potentiality that reduce noise also must be extremely huge certainly.

Sacrifice some careats, chamber interior volume in fact, in order to reduce significantly the ventilation noise be one extremely meaningful, extremely valuable thing be as the saying goes: " rich can't buy quietness ".Can be with limited, few money of trying one's best has been bought pure and fresh air, quiet environment, the city of prosperity was the very thing of difficulty of part in modern age.For example: clean and 2003 the 4th phases of air-conditioning magazine, among the Liu Yufeng, Shen Jin is bright to be shown " Shenzhen office building indoor air quality subjective assessment and correlation analysis " literary composition, a building was come into operation more than 10 year construction area 60000m ²Office building made the environmental quality subjective survey, the result has 53% people can not accept room noise environment subjectivity, has 24.3% people can not accept the indoor air quality subjectivity.Therefore when taking to improve the measure of indoor air quality,, also must implement the principle of saving certainly, take careat, the interior space as far as possible less, the simplified structure of trying one's best, reduce expenses in any case all must take into account the improvement of noise performance.

So, how many should specific requirements that reduces noise be? the quiet standard that general air conditioner ventilation circle is proposed is 25dB (A).Can this standard be as the lowest limit or the target that reduce noise? this is a very low standard in fact, because human body is extremely responsive, he can hear the sound near odB, particularly to the sound of high audio, the sound of 10dB, most people can very clearly hear, and blower fan, air-conditioning noise mainly are exactly high frequency noise; And for consideration energy-conservation, that save the air-conditioning investment, people are generally with the nucleus of this main noise source of air-conditioner air outlet over against the room.We feel that the air-conditioning noise is very disagreeable, unless very necessary, be reluctant in the bedroom, to move for a long time air conditioner, reason is difficult to stand for a long time exactly.The quiet standard of 25～35dB (A) never is gratifying, a high standard.And 25dB (A) is two different notions with allowing noise grade standard 25dB (N), and 25dB (N) is at the frequency band range greater than 1000Hz, less than or be significantly smaller than the fan noise of 25dB (A).Consult " architectural design data collection (1) " that Beijing industrial building design institute compiles 133 pages,

Allow the noise grade calibration curve.Require satisfying the living environment that people improve day by day from high standard all sidedly,, quiet standard should be brought up to about 10dB (A) from actual objective experience to the harm of electric fan device noise.And the criteria for noise of 10dB (A) is for the various air-conditioning products of existing structure, various ventilation blower products, and various air-conditioning and construction things all may not reach.Reach about 25dB (A), almost reached the limit that they can be accomplished, near this level, every reduction 1dB (A) is very difficult, costly, and good especially to the subjective inductive effects of human body.And adopt no volume area hard limit of the present invention combine together with building, the electrically ventilating device (57) in the airtight good broad sense air-conditioning system of surrounding air is comprised, air filtering box (37), overfire air fan (52), indoor apparatus of air conditioner (30) can reach this very high criteria for noise of 10dB (A) easily.This electrically ventilating device (57) also can comprise aforesaid filtration cell (23) and air-conditioner outdoor unit.

With the embodiment shown in the accompanying drawing 13 this is described in further detail below.

Accompanying drawing 13 is vertical section schematic diagrames.

Electrically ventilating device (57) is air filtering box (37), overfire air fan (52), and the general designation of indoor apparatus of air conditioner (30), air-conditioner outdoor unit or air-conditioning unit (17), their core component all is electrically ventilating machines.

The electrically ventilating device (57) of the low noise shown in the accompanying drawing 13 is characterised in that:

A, adopt concrete, silico-calcium magnesium, calcium silicates, building block brick, glass, stone material, plastics, rubber, plastic-aluminum, surpass the sheet material of the thick metal material of 1.8mm, or their composite board, combined plate, section bar, prefabricated section make housing, or adopt the good material of above-mentioned sound insulation value to make the sound insulation casing (53) of outsourcing or filtration cell (23), sealing cell (35) outside their housing;

B, within the above-mentioned housing or within the outsourcing sound insulation casing (53) by multiple light silencing plate or high up in the air the light silencing plate is set or bore a hole continuously abatvoix or compound be provided with above-mentioned by compound plate and plate (54) high up in the air and sound insulation guide plate (56), inlet side at above-mentioned housing or outsourcing sound insulation casing (53) can be provided with sound insulation cover plate (62);

One to four face of the housing of c, above-mentioned material or sound insulation casing, cell can adopt the wall of building, floor to replace, thereby make itself and building form incorporate overall structure; According to the position of its air outlet with respect to the floor, can be divided into a high position, meta, low level ventilation unit (57), divide according to its position with respect to the effect room, can be divided into indoor ventilator unit or next door ventilation unit (57);

D, can on the Blower Housing and rotating blade of ventilation unit (57), play the perforation of continuous distributed and carry out resonance acoustical absorption;

E, electrically ventilating device (57) can be installed on the vibration isolation sealing gasket (55) that is positioned at casing (53) middle part or bottom, and this pad (55) and the plate, frame, the step that are used to install this pad are divided into this sound insulation casing (53) inlet plenum (59) and air-out anechoic chamber (58) two parts that are positioned at upper-lower position or front and back position.

Illustrate: air filtering box (37), secondary blower fan (52), air conditioner (30) etc. all is equipped with electric fan, all belongs to the electrically ventilating device.

These several devices all need air filter, and secondary blower fan (52) can not possess the filter that belongs to self, for no other reason than that the second ring of its inspiration domestic air has passed through the filtration of air filtering box (37) etc.The pre-filtering of degree of precision such as (37) is arranged certainly, and air conditioner (30) also can not have the filter that belongs to self, does not exchange words to say, and they are equipped with the filter that belongs to self, and so, the filter effect of air can be better.

Its thickness of thick metallic plate for example can be decided to be 2.5 to 3mm greater than 1.8mm.The sheet metal thickness that general household electrical appliance adopt is about 0.8～1mm.Do that like this volume of indoor Rose Box (37) and overfire air fan (52) and indoor apparatus of air conditioner is increased, but as long as need in conjunction with decoration condition, decoration, design scientifically and rationally, the increase of this volume usually has only 0.1～1m ³To be very limited, do not hinder attractive in appearance, can be received, the effect of doing sound-absorbing, sound insulation, noise reduction like this will be huge, for example:

Adopted the thick sheet metal of 3mm to increase 11dB than the sound transmission loss of the sheet material that uses the thick same material of 0.8mm.The sound transmission loss of building block brick wall or concrete wall can reach 50dB, and the sound transmission loss of the combined plate of the silico-calcium magnesium plate of two-layer 0.9 cm thick or calcium silicates plate holder one deck light silencing material can reach 45dB (consulting the operation instructions of the silico-calcium magnesium plate (the solid power plate in excellent sharp chamber) of Kunyang Building Materials (Kunshan) Co., Ltd.).

The sound insulation value of composited aluminum and plastic decking is also good.Can adopt the method for adding high-gravity filler or foaming to improve the sound insulation value or the sound absorption qualities of plastic material or elastomeric material (can be hard or soft).

Paste by multiple light silencing sheet material or the method for designing that light silencing plate, porous sound absorbing plate and sound panel are set high up in the air in inner walls, belong to the work that general audio engineering personnel are easy to accomplish, the acoustic construction of the quiet wind pushing box of FV-12NSIC type that concrete structure can be produced with reference to Songxia Jinggong Co., Ltd., Shunde City.This fan delivery reaches 180m ³/ h, static pressure reaches 113Pa, and noise content only is 23dB (A).

Just think: after this blower fan or air filtering box of the present invention (37) or certain indoor apparatus of air conditioner were carried out outsourcing with outsourcing sound insulation casing of the present invention (53), its noise content was lowered to about 10dB (A) and should be not difficult.And the price of this casing of making of general materials for wall is quite cheap.

Certainly: behind the outsourcing sound proof box, the air outlet part of air outlet and the sound proof box of reply said apparatus is tightly connected and the careful design of noise reduction sound insulation vibration isolation, tries to achieve the unobstructed harmony with the noise reduction sound insulation value of air-out.In order to reduce the noise that electrically ventilating device (57) produces, especially anti-noise here spreads out of from the air outlet of outsourcing sound insulation casing (53), can the electronics silencing means be set in the air-out position in this casing.Also can utilize the resonance acoustical absorption principle to carry out noise reduction playing the perforation of continuous distributed on the Blower Housing of ventilation unit (57) and on the rotor sheet, small perforation influences the ventilation effect of blower fan can be not big.And can adopt light silencing material sealing perforation.

Wherein note: the proportion of silico-calcium magnesium plate can only have 0.79/cm3, and can carry out veneer with paper, plastics, nonwoven etc., and also available metal thin plate or cellular insulant carry out veneer, its processing, and the performance classes of use is similar to aluminium-plastic panel.The electrically ventilating device (57) that uses above-mentioned this silico-calcium magnesium plate or its composite board or combined plate to make should be light portable, and this material should also can be used for doing the cabinet housing (1) of combined air conditioner machine, makes it improve sound insulation value greatly.

When above-mentioned air filtering box ventilation units such as (37) and their outsourcing sound insulation casing adopt material such as concrete, silico-calcium magnesium, thick metal and compound, combination thereof, they can be designed and produced integrated member with building one form.Housing wherein or outsourcing sound insulation casing can be made into prefabricated component or prefabricated shaped-section.For example can make the section bar of channel steel shape as Figure 13, it and a certain metope one amalgamation just become cabinet shape structure, can be used to make sound proof box casing (53).

The integral of this building and air conditioner ventilating system designs, is convenient to integrate the design and the building course of air-conditioning supply air system and residential building, adopt system engineering better, value engineering, relevant technologies, economic performance index that modernizations such as total quality control design, management means come to promote all sidedly, significantly building and air conditioner ventilating system.Present relatively, simple residential housing or other industrial and commercial building, this and the integrated integration mode of essence air conditioner ventilating system, existing increase air conditioner ventilation facility polyvoltine money, take the place of construction area and space more, also just like preceding described a lot of saving interior spaces, simplify and decorate structure, save the energy, promote the place of comfortableness.On the whole, can accomplish real getting twice the result with half the effort, can change money less or not change money even saving money ground realization dwelling house or the essence of building, revolutionary lifting performance and update.This design and mode of construction have height go-beyond technology economic worth, have for the building circle, decorate the boundary, furniture circle, and the numerous designers of air-conditioning circle, administrative staff deeply excavate, the broad space of giving full play to.

For example with respect to the wind pipe type air-conditioning system, this air conditioner ventilating system can be dropped to about 2.6m by 2.9m the minimum requirements of building floor height, can reduce dwelling house cover inner volume about 8% as previously mentioned, probably is every 100m ²Careat can reduce by 20～30m ³Volume reduces dwelling house and builds and decorate cost about 10%.This saving obviously is very huge, is (annotating: the acquisition expenses that does not also calculate air-conditioning system self here) well beyond the amount of money of spending more expense.

For air conditioner outdoor unit: its outsourcing sound insulation casing can be reduced to the plane that is positioned at the outer suitably distance of fan mouth or the gobo of folding face shape, in order to avoid influence its air velocity.Its noise reduction volume is smaller, and purpose is to reduce the noise jamming to self or neighbours on the direction of propagation of key.

When general air-conditioning (indoor) machine (30) is installed in the sound insulation casing (53), because be subjected to the restriction of case inner volume, door is installed, the influence of vibration isolation sealing gasket and support structure thereof, it is very difficult that the sector-meeting of replacing airstrainer is installed, should adopt simple in structure, cheap, vertical or the horizontal fan coil of no air filter (must carry out necessary repacking, to adapt to it is installed in sound insulation casing (53) by sealing vibration isolator (55) concrete condition), had better design special horizontal and vertical fan coil with the mounting structure that cooperates with sealing vibration isolator (55).
