Description

TECHNIKOS SRITISTECHNICAL FIELD

Šis išradimas susijęs su oro vėdinimo sistemomis, konkrečiai, su šiose sistemose naudojamais šilumokaičiais.The present invention relates to air ventilation systems, in particular to heat exchangers used in such systems.

TECHNIKOS LYGIS io Yra žinoma keletas šilumokaičių, montuojamų vėdinimo sistemose, tipų. Dažniausiai naudojami priešpriešinių ir kryžminių srautų šilumokaičiai, kuriuose iškvėpuotas patalpos oras atiduoda šiluminę energiją iš lauko ateinančiam orui. Šilumokaičiai vaidina ypatingai didelį vaidmenį šaltojo sezono metu, kada iš vėdinamos patalpos kartu su išeinančiu prikvėpuotu oru išeina ir šiluma ir drėgmė, o į patalpas patenka sausas ir šaltas lauko oras.BACKGROUND OF THE INVENTION Several types of heat exchangers for installation in ventilation systems are known. The most commonly used heat exchangers are counter-flow and cross-flow, where the exhaled indoor air releases thermal energy to the outside air. Heat exchangers play a particularly important role during the cold season, when the ventilated rooms, together with the exhaled air, leave out heat and humidity, and the rooms enter dry and cold outdoor air.

Paprastai minėti šilumokaičiai yra gaminami panaudojant aliuminio folijos kompozicijas. Aliuminis yra geras šilumos laidininkas, tačiau visiškai nepraleidžia drėgmės. Kartais šilumokaičiuose naudojamas drėgmei ir šilumai laidus popierius, šilumokaičiuose, pagamintuose iš šio popieriaus, pakankamai gerai vyksta šilumos ir drėgmės atidavimas iš šilto ir drėgno oro šaltam ir sausam orui. Popierinių šilumokaičių pagrindinis trūkumas - tai, kad sudrėkus popieriui ilgainiui keičiasi pačio šilumokaičio forma - šilumokaitis deformuojasi, taip pat vyksta trumpalaikis grįžtamasis sudrėkusio popieriaus plėtimasis, ši popierinio šilumokaičio savybė riboja tokio šilumokaičio panaudojimą drėgnose patalpose. Svarbu paminėti, kad, gaminant priešpriešinių srautų šilumokaičius, gofruotų sluoksnių formavimui aliuminio folija netinka, kadangi, formuojant iš esmės trijų krypčių gofrus, aliuminio folija lengvai plyšta šių gofrų sudūrimuose.Generally, said heat exchangers are manufactured using aluminum foil compositions. Aluminum is a good conductor of heat, but it is completely impermeable to moisture. Sometimes heat and moisture-permeable paper is used in heat exchangers, and heat and moisture transfer from warm and humid air to cold and dry air is done well in heat exchangers made from this paper. The main disadvantage of paper heat exchangers is that when the paper gets wet, the shape of the heat exchanger itself changes over time - the heat exchanger is deformed and the wetted paper expands temporarily, this property of the paper heat exchanger restricting its use in wet rooms. It is important to note that aluminum foil is not suitable for the formation of corrugated layers in counterflow heat exchangers, because when forming essentially three-way corrugations, aluminum foil tears easily at the joints of these corrugators.

Taip pat žinomas amerikiečių patentas Nr. US2001032714, publikuotas 2001 m. spalio 25 d. Šiame patente taip pat aprašomas ventiliavimo sistemos elementas, kur pagrindinė jo funkcija yra vykdyti šiluminius mainus tarp iškvėpuoto oro ir įeinančio gaivaus oro, tuo pačiu, visiškai išvengiant šių dviejų srautų tarpusavio įo maišymosi. Tuo tikslu, oro srautų latakai suformuojami iš plastiko.Also known is U.S. Pat. US2001032714, published 2001. October 25 This patent also describes an element of a ventilation system where its primary function is to perform a thermal exchange between the exhaled air and the incoming fresh air while completely avoiding intermixing of the two streams. For this purpose, the air flow ducts are formed of plastic.

Taip pat žinoma aktuali tarptautinė patentinė paraiška VVO8607133, publikuota 1986 m. gruodžio 4 d. Šiuo išradimu sprendžiama šilumokaičio gamybos problema, kai plastikinių gofruotų sluoksnių sujungimui panaudojamas ultragarsinis arba radijo bangų suvirinimas.Also known is the current international patent application VVO8607133, published June 1986. December 4th The present invention solves the problem of manufacturing a heat exchanger using ultrasonic or radio wave welding for the connection of plastic corrugated layers.

Visi minėti išradimai remiasi įvairių medžiagų panaudojimu šilumokaičių gamyboje, tokiu būdu sprendžiant šilumos ir/arba drėgmės atidavimo tarp išeinančio iškvėpuoto oro ir įeinančio gaivaus oro problemas. Tačiau nė viename iš šių išradimų nepasiūlytas universalus variantas - kad ventiliavimo sistemose naudojamame šilumokaityje būtų atliekamas geras šilumos bei drėgmės atidavimas, tokiu būdu sumažinant šių dviejų komponentų praradimą. Tai ypač svarbu patalpoms, kuriose gyvena arba dirba žmonės. Taip pat pats šilumokaitis turėtų nesideformuoti veikiamas drėgmės. Tokį šilumokaitį, atitinkantį visus tris kriterijus galima pagaminti tik teisingai parinkus medžiagas ir jų išdėstymą. Taip pat labai svarbu, kad iš parinktos medžiagų kompozicijos būtų galima suformuoti tiek kryžminių, tiek ir priešpriešinių srautų šilumokaitį.All of the above-mentioned inventions rely on the use of various materials in the manufacture of heat exchangers, thus solving the problems of heat and / or moisture transfer between the exhaled exhaled air and the incoming fresh air. However, none of these inventions offer the versatile option of having a good heat and moisture transfer in the heat exchanger used in ventilation systems, thereby reducing the loss of these two components. This is especially important for rooms where people live or work. Also, the heat exchanger itself should not deform under the influence of moisture. Such a heat exchanger, which meets all three criteria, can only be manufactured with the correct choice of materials and their arrangement. It is also very important that a cross-flow and counter-flow heat exchanger can be formed from the selected material composition.

IŠRADIMO ESMĖTHE SUBSTANCE OF THE INVENTION

Šiuo išradimu siekiama sukurti priešpriešinių srautų šilumokaitį, skirtą oro ventiliavimo sistemoms. Šiame šilumokaityje turėtų sklandžiai vykti šilumos ir drėgmės mainai, o pats šilumokaitis turėtų santykinai mažas deformacijas veikiant šiems dviems veiksniams.The present invention seeks to provide a counter flow heat exchanger for air ventilation systems. This heat exchanger should have a smooth heat and humidity exchange and the heat exchanger itself would have relatively little deformation under these two factors.

Remiantis šiais kriterijais, sukurtas priešpriešinių srautų šilumokaitis, kurio gofruoti sluoksniai yra pagaminti iš plastiko, o pertvaros tarp šių sluoksnių suformuojamos iš drėgmei ir šilumai laidaus popieriaus. Kadangi gofruotų sluoksnių gamybai naudojamas plastikas, atsiranda papildoma galimybė suformuoti papildomus iškilimus, kurie suvienodintų oro srautų judėjimą visu skerspjūviu.Based on these criteria, a counter-flow heat exchanger is formed, with corrugated layers made of plastic and the partitions between these layers formed of moisture and heat-conductive paper. Because of the use of plastic in the production of corrugated layers, there is an additional possibility of forming additional protrusions that would smooth the movement of the air flows across the cross-section.

Šilumokaitis, atitinkantis šiuos kriterijus gali būti sėkmingai pritaikomas konstruojant kvėpavimo įrangą alpinistams, kadangi kalnų višukalnėse oras yra šaltas, o santykinė oro drėgmė labai maža; žmogus tokiose sąlygose su iškvepiamu oru netenka labai daug drėgmės, o įkvepiamame ore drėgmės procentas yra labai mažas (priklausomai nuo oro temperatūros). Kvėpavimo aparatas, pagamintas remiantis šiuo išradimu padėtų sumažinti drėgmės nuostolius. Dėl tų pačių priežasčių šie šilumokaičiai gali būti naudojami portatyvinėje kvėpavimo įrangoje, skirtoje žmonėms, sergantiems kvėpavimo takų ligomis.A heat exchanger that meets these criteria can be successfully applied to the construction of breathing equipment for mountaineers because of the cold air and the relative humidity of the air in the mountain foothills; the person loses a lot of moisture in these conditions with exhaled air and the percentage of humidity in the inhaled air is very low (depending on the air temperature). A respirator made according to the present invention would help to reduce moisture loss. For the same reasons, these heat exchangers can be used in portable respiratory equipment for people with respiratory disease.

TINKAMIAUSI ĮGYVENDINIMO VARIANTAIPREFERRED EMBODIMENTS

Tinkamiausias šio išradimo įgyvendinimo variantas yra priešpriešinių srautų šilumokaitis, sudarytas iš sluoksnių (1,2), pavaizduotų Fig. 2. Kiekvienas sluoksnis (1,2) yra suformuojamas iš esmės vienodų plokštuminių matmenų popierinės tarpinės (1) ir gofruotos plastikinės tarpinės (2). Šios dvi tarpinės yra sujungiamos tarpusavyje klijavimo, suvirinimo ar kitu būdu ir sudaro vieną šilumokaičio sluoksnį. Tokie sluoksniai yra tvirtinami vienas ant kito, pasukant juos 180’ vienas kito atžvilgiu apie ašį Z. Tokiu būdu suformuojama struktūra, pavaizduota Fig. 1. Tokios struktūros kas antrame sluoksnyje oro srautas nukreiptas viena kryptimi, o likusiuose tarpiniuose sluoksniuose - priešinga kryptimi.A preferred embodiment of the present invention is a counter flow heat exchanger consisting of layers (1,2) shown in FIGS. Each layer (1,2) is formed by a paper gasket (1) of substantially uniform planar dimensions and a corrugated plastic gasket (2). These two gaskets are joined together by gluing, welding or otherwise and forming a single layer of heat exchanger. Such layers are superimposed on one another by rotating them 180 'with respect to each other about axis Z. The structure of FIG. 1. In every second layer of this structure, the air flow is directed in one direction and in the other intermediate layers in the opposite direction.

Pimame įgyvendinimo variante iškvėpuotas oras patenka į šilumokaitį pro šoną(GH), o išeina iš jo šone (C-D). Oras iš lauko patenka į šilumokaitį pro šoną(G-F) ir iš šilumokaičio išeina pro šoną (D-E). Srityse (G-H-F) ir (C-D-E) iškvėpuoto ir gaivaus oro srautai susikerta kampu artimu arba lygiu 90*, srityje (H-C-E-F) šie oro srautai yra nukreipti priešpriešiais. Kaip tik šioji sritis yra efektyviausia šilumos ir drėgmės mainams, todėl nuo jos ilgio tiesiogiai priklauso šilumokaičio efektyvumas. Šiame įgyvendinimo variante oro kelias yra nevienodas skirtinguose šilumokaičio šonuose, pavyzdžiui, iš lauko ateinančio oro kelias atkarpoje (F-E) yra daug trumpesnis nei trajektorijoje (G-H-C-D) dėl to oras, einantis atkarpa (F-E) nespėja pasiimti tiek šilumos ir drėgmės, kiek šių komponentų paima oras, einantis trajektorija (G-H-C-D). Dėl šios priežasties galimas antras išradimo įgyvendinimo variantas, pavaizduotas Fig. 3, kai gofruoto sluoksnio (2) srityje, apribotoje kontūru (4), yra suformuojami iškilimai, sukuriantys pasipriešinimą oro tekėjimui ir tokiu būdu suvienodinantys oro srautą visame šilumokaičio skerspjūvyje. Fig. 4 pavaizduotas plastikinio gofruoto sluoksnio (2) fragmentas, kuriame matomi mažų matmenų, lyginant su gofro plokštumos pločiu, nelygumai, suformuoti kaip gofrų plokštumose įspausti, skersai gofrų krypties einantys loveliai (5).In one embodiment, the exhaled air enters the heat exchanger through the side (GH) and exits the side (C-D). The outside air enters the heat exchanger sideways (G-F) and exits the heat exchanger sideways (D-E). In Areas (G-H-F) and (C-D-E), exhaled and fresh air flows intersect at an angle close to or equal to 90 *, while in Area (H-C-E-F), these air flows are directed opposite. It is this area that is most efficient for exchanging heat and humidity, so its length directly influences the efficiency of the heat exchanger. In this embodiment, the air path is unequal on different sides of the heat exchanger, for example, the outgoing air path in the section (FE) is much shorter than in the trajectory (GHCD), causing the air in the section (FE) to not absorb as much heat and moisture as these components. air following trajectory (GHCD). For this reason, a second embodiment of the invention shown in FIGS. 3, where bumps are formed in the region of the corrugated layer (2) bounded by the contour (4), creating resistance to the flow of air and thus equalizing the air flow across the cross-section of the heat exchanger. FIG. Fig. 4 shows a fragment of a plastic corrugated layer (2), showing irregularities of small dimensions relative to the width of the corrugation, formed as troughs (5) transverse to the direction of the corrugations.

Šie šilumokaičio variantai gali būti pritaikomi patalpų ventiliacijos sistemose arba kvėpavimo įrenginiuose, pavyzdžiui, alpinistų naudojamuose kvėpavimo aparatuose, ar portatyviniuose kvėpavimo aparatuose žmonėms, sergantiems kvėpavimo takų ligomis.These heat exchanger variants can be applied to indoor ventilation systems or respiratory equipment, such as mountaineering breathing apparatus, or portable breathing apparatus for people with respiratory disease.
