Infrapunas\u00e4teily mainitaan usein eri artikkeleissa, erityisesti hiilikuituisten infrapunal\u00e4mp\u00f6putkien yhteydess\u00e4, s\u00e4teilyl\u00e4mmityksen muotona. Mit\u00e4 siis on s\u00e4teilyl\u00e4mmitys? T\u00e4n\u00e4\u00e4n annan yksityiskohtaisen selityksen l\u00e4mp\u00f6s\u00e4teilyst\u00e4, joka on yksi kolmesta l\u00e4mm\u00f6nsiirtotavasta.<\/p>\n\n\n\n
S\u00e4teily on energiansiirtomenetelm\u00e4, jossa k\u00e4ytet\u00e4\u00e4n s\u00e4hk\u00f6magneettisia aaltoja. Kohteet l\u00e4hett\u00e4v\u00e4t s\u00e4teily\u00e4 eri syist\u00e4, ja l\u00e4mp\u00f6s\u00e4teilyksi kutsutaan ilmi\u00f6t\u00e4, jossa s\u00e4teily\u00e4 l\u00e4htee l\u00e4mm\u00f6n vuoksi. Luonnossa jokainen esine l\u00e4hett\u00e4\u00e4 jatkuvasti l\u00e4mp\u00f6s\u00e4teily\u00e4 ymp\u00e4r\u00f6iv\u00e4\u00e4n tilaan ja imee samanaikaisesti muiden esineiden l\u00e4hett\u00e4m\u00e4\u00e4 l\u00e4mp\u00f6s\u00e4teily\u00e4. Infrapunaskannerin alla kaikki kohteet n\u00e4ytt\u00e4v\u00e4t jonkinlaisen l\u00e4mp\u00f6tilamerkinn\u00e4n tai skannauskuvan, lukuun ottamatta teoreettisesti puhdasta mustaa kappaletta, jolla ei ole l\u00e4mp\u00f6s\u00e4teily\u00e4.<\/p>\n\n\n\n
Luonnolliset s\u00e4teily- ja absorptioprosessit johtavat yhdess\u00e4 kohteiden v\u00e4liseen l\u00e4mm\u00f6nsiirtoon s\u00e4teilyn avulla, joka tunnetaan yleisesti my\u00f6s nimell\u00e4 infrapunas\u00e4teilyn l\u00e4mm\u00f6nsiirto. Kun kohde on l\u00e4mp\u00f6ep\u00e4tasapainossa ymp\u00e4rist\u00f6ns\u00e4 kanssa, s\u00e4teilev\u00e4 l\u00e4mm\u00f6nsiirto on nolla. T\u00e4m\u00e4 ei kuitenkaan tarkoita sit\u00e4, ett\u00e4 ymp\u00e4rist\u00f6ss\u00e4 ei olisi s\u00e4teilynvaihtoa; pikemminkin ymp\u00e4rist\u00f6n kohteiden s\u00e4teilem\u00e4 energia on yht\u00e4 suuri kuin niiden absorboima energia, jolloin saavutetaan suhteellinen tasapaino, jossa s\u00e4teily- ja absorptioprosessit ovat jatkuvasti aktiivisia.<\/p>\n\n\n\n
Toisin kuin s\u00e4teily, kaksi muuta l\u00e4mm\u00f6nsiirtotapaa, johtuminen ja konvektio, vaativat energian siirt\u00e4miseen v\u00e4liaineen, kuten kiinte\u00e4t aineet, ilman, veden tai muut kaasut ja nesteet, mukaan lukien niiden seokset. S\u00e4teily ei vaadi v\u00e4liaineen k\u00e4ytt\u00f6\u00e4, ja se voi tapahtua jopa tyhji\u00f6ss\u00e4, mik\u00e4 tekee siit\u00e4 tehokkaimman l\u00e4mm\u00f6nsiirtomenetelm\u00e4n tyhji\u00f6olosuhteissa. T\u00e4m\u00e4 ero on olennainen ominaisuus, joka erottaa s\u00e4teilyn johtumisesta ja konvektiosta. Kun tyhji\u00f6 erottaa kaksi kohdetta toisistaan, johtumista tai konvektiota ei voi tapahtua, vaan l\u00e4mm\u00f6nsiirto on mahdollista vain s\u00e4teilyn avulla.<\/p>\n\n\n\n
Auringonvalon kuljettama energia siirtyy avaruuden valtavan tyhji\u00f6n l\u00e4pi Maahan l\u00e4mp\u00f6s\u00e4teilyn avulla, jossa kaikki el\u00e4v\u00e4t olennot imev\u00e4t sen itseens\u00e4 ja hy\u00f6dynt\u00e4v\u00e4t sit\u00e4. Termospullojen ja tyhji\u00f6eristettyjen mukien kaltaisissa arkip\u00e4iv\u00e4isiss\u00e4 esineiss\u00e4 hy\u00f6dynnet\u00e4\u00e4n tyhji\u00f6eristyksen periaatetta l\u00e4mp\u00f6eristyksen ja l\u00e4mp\u00f6tilan erottamisen saavuttamiseksi. S\u00e4teilyl\u00e4mm\u00f6nsiirtoon liittyy my\u00f6s se, ett\u00e4 siin\u00e4 ei ole kyse pelk\u00e4st\u00e4\u00e4n energian siirrosta vaan my\u00f6s energiamuotojen muuntamisesta; energiaa vapautuu s\u00e4teilyenergiana ja muuntuu takaisin l\u00e4mp\u00f6energiaksi absorboitumisen yhteydess\u00e4.<\/p>\n\n\n\n
Kokeet ovat osoittaneet, ett\u00e4 kappaleen kyky s\u00e4teill\u00e4 riippuu l\u00e4mp\u00f6tilasta, ja samassa l\u00e4mp\u00f6tilassa eri kappaleiden s\u00e4teily- ja absorptiokyky vaihtelee. Ihanteellinen materiaali, jota kutsutaan mustaksi kappaleeksi, voi absorboida kaiken s\u00e4teilyenergian, vaikka t\u00e4llaiset materiaalit ovatkin harvinaisia tosiel\u00e4m\u00e4ss\u00e4. T\u00e4m\u00e4 infrapunas\u00e4teilyn absorption vaihtelevuus eri materiaaleissa on syyn\u00e4 siihen, miksi erityyppiset l\u00e4mmitysputket valitaan tuotteen mukaan, kun hiilikuitul\u00e4mmitysputkia k\u00e4ytet\u00e4\u00e4n materiaalien kuivaamiseen.<\/p>\n\n\n\n
