CO2 incubator inoburitsa condensation, hunyoro hwehukama hwakanyanya here?
Patinoshandisa CO2 incubator kurima masero, nekuda kwekusiyana kwehuwandu hwemvura yakawedzerwa uye kutenderera kwetsika, tine zvinodiwa zvakasiyana zvehunyoro hwehukama muincubator.
Pakuedza kushandisa 96-tsime sero tsika mahwendefa ane kureba tsika kutenderera, nokuda kwehuwandu hwemvura yakawedzerwa kune imwe tsime, pane njodzi yokuti mhinduro yetsika inooma kana ikaputika kwenguva yakareba pa 37 ℃.
Higher hama humidity ari incubator, semuenzaniso, kusvika kupfuura 90%, anogona zvinobudirira kuderedza evaporation yemvura, zvisinei, dambudziko idzva ramuka, vakawanda sero tsika experimentalists vakawana kuti incubator iri nyore kubudisa condensate mumamiriro akanyanya mwando, condensate kugadzirwa kana isingadzoreki, ichaunganidza tsika yakawanda uye yakaunza humwe hutachiona hwehutachiwana hwehutachiwana hwehutachiona.
Saka, chizvarwa che condensation mu incubator nekuti hunyoro hwehukama hwakanyanya kukwirira?
Chokutanga pane zvose, tinofanira kunzwisisa pfungwa yehunyoro hunyoro,hunyoro hunoenderana (Relative Humidity, RH)ndicho chaicho chiri mukati memhute yemvura mumhepo uye chikamu chehuwandu hwemhute yemvura pakuzara patembiricha imwe chete. Inoratidzwa mufomula:

chikamu chehuwandu hwehunyoro hunomiririra reshiyo yehutsi hwemvura huri mumhepo kusvika pahuwandu hunobvira huripo.
Zvakananga:
0% RH:Hakuna mhute yemvura mumhepo.
* 100% RH:Mhepo yakazadzwa nemhute yemvura uye haigoni kubata imwe mhute yemvura uye condensation ichaitika.
50% RH:Zvinoratidza kuti huwandu hwazvino hwemhute yemvura iri mumhepo ihafu yehuwandu hwemhute yemvura yakaguta patembiricha iyoyo. Kana tembiricha iri 37°C, ipapo kuzara kwemhute yemvura kunenge kuri 6.27 kPa. Naizvozvo, mhepo yemhute yemvura pa50% hunyoro hunoenderana ne3.135 kPa.
Saturated mvura mhute pressurendiko kudzvinyirirwa kunoitwa nemhute muchikamu chegasi kana mvura yemvura nemhute zvayo zviri muhumwe hunochinja pane imwe tembiricha.
Kunyanya, kana mhute yemvura uye mvura yemvura yakabatana mune yakavharwa system (semuenzaniso, yakavharwa-yakavharwa Radobio CO2 incubator), mamorekuru emvura acharamba achichinja kubva kune yemvura kuenda kune gaseous state (evaporation) nekufamba kwenguva, nepo zvakare gaseous mvura mamorekuru acharamba achichinja kune iyo mvura mamiriro (condensation).
Pane imwe nguva, mazinga evaporation uye condensation akaenzana, uye mhute yemhepo panguva iyoyo ndiyo yakazara mvura mhute pressure. Inoratidzwa ne
1. Dynamic equilibrium:apo mvura uye mhute yemvura inogara mune yakavharwa system, evaporation uye condensation kuti isvike pakuenzanisa, kumanikidzwa kwemhute yemvura muhurongwa haisisiri kuchinja, panguva ino kudzvinyirira kwakazara kwemvura vapor pressure.
2. kutsamira kwekushisa:saturated water vapour pressure inoshanduka netembiricha. Kana tembiricha ichiwedzera, simba rekinetic remamorekuru emvura rinowedzera, mamwe mamorekuru emvura anogona kutizira kuchikamu chegasi, saka iyo yakazara mvura mhute yekumanikidza inowedzera. Sezvineiwo, kana tembiricha yadzikira, iyo yakazara mhute yemvura inoderera.
3. Hunhu:saturated water pressure is a pureely material character parameter, haibvi pahuwandu hwemvura, chete netembiricha.
Nzira yakajairika inoshandiswa kuverenga yakazara mvura vapor pressure ndiyo Antoine equation:
Kumvura, iyo Antoine isingachinji ine hunhu hwakasiyana hwemhando dzakasiyana dzetembiricha. A common set of constants ndeaya:
* A=8.07131
* B=1730.63
* C=233.426
Iyi seti yezvigadziriso inoshanda kune tembiricha kubva pa1 ° C kusvika 100 ° C.
Tinogona kushandisa zvigadziriso izvi kuverenga kuti mvura yakazadza dzvinyiriro pa37°C i6.27 kPa.
Saka, imvura yakawanda sei mumhepo pa37 degrees Celsius (°C) mumamiriro ekuzara kwemhute yemvura?
Kuverenga huwandu hwehuwandu hwehuputi hwemvura yakazara (absolute humidity), tinogona kushandisa iyo Clausius-Clapeyron equation formula:
Saturated mvura mhute pressure: Pa 37°C, yazara mvura mhute pressure i 6.27 kPa.
Kushandura tembiricha kuita Kelvin: T=37+273.15=310.15 K

mhedzisiro inowanikwa nekuverenga ndeye 44.6 g/m³.
Pa 37°C, hunyoro hwemvura (absolute humidity) pakuzara hunoita 44.6 g/m³. Izvi zvinoreva kuti cubic mita imwe neimwe yemhepo inogona kubata 44.6 magiramu emhute yemvura.
A 180L CO2 incubator inongobata magiramu masere emhute yemvura.Kana humidification pani pamwe netsika midziyo yakazadzwa nezvinwiwa, hunyoro hwehukama hunogona kusvika nyore pahukoshi hwepamusoro, kunyangwe padhuze nesaturation humidity values.
Kana hunyoro hwehukama hunosvika 100%,mhute yemvura inotanga kupera. Panguva ino, huwandu hwemhute hwemvura mumhepo hunosvika pakukosha kwainokwanisa kubata patembiricha yazvino, kureva saturation. Kumwe kuwedzera kwemhute yemvura kana kudzikira kwetembiricha kunoita kuti mhute yemvura imonere kuita mvura yemvura.
Condensation inogonawo kuitika kana hunyoro hunopfuura 95%,asi izvi zvinoenderana nezvimwe zvinhu zvakaita setembiricha, huwandu hwemhute yemvura mumhepo, uye tembiricha yepamusoro. Izvi zvinofurira zvinhu zvinotevera:
1. Kuderera kwekushisa:Kana huwandu hwemhute hwemvura mumhepo hwave pedyo nekuzara, chero kuderera kudiki kwekushisa kana kuwedzera kwehuwandu hwemhute yemvura kunogona kukonzera condensation kuitika. Semuenzaniso, kushanduka kwekushisa mu incubator kunogona kutungamirira kuchizvarwa che condensate, saka tembiricha yakanyanya kugadzikana incubator ichava ne inhibitory effect pachizvarwa che condensate.
2. Tembiricha yenzvimbo iri pasi petembiricha yedova:tembiricha yepasi penzvimbo yakadzikira pane tembiricha yedova, mhute yemvura inomonerera kuita madonhwe emvura panzvimbo idzi, saka tembiricha yakafanana yeincubator ichaita zvirinani mukudzivirirwa kwe condensation.
3. Kuwedzera kwemhute yemvura:semuenzaniso, humidification pani uye midziyo yetsika ine huwandu hukuru hwemvura, uye incubator yakavharwa zviri nani, kana huwandu hwemhute hwemhepo mumhepo mukati meincubator huchiwedzera kupfuura huwandu hwayo hwekugona panguva ino tembiricha, kunyangwe tembiricha ikaramba isingachinji, condensation ichagadzirwa.
Naizvozvo, CO2 incubator ine yakanaka tembiricha control zviri pachena ine inhibiting mhedzisiro pachizvarwa che condensate, asi kana hunyoro hwehukama hunopfuura 95% kana kutosvika pakuzara, mukana wekuti condensation uwedzere zvakanyanya.saka, patinenge tichirima masero, kunze kwekusarudza yakanaka CO2 incubator, tinofanira kuedza kudzivisa njodzi ye condensation inounzwa nekutsvaga kwekunyorova kwepamusoro.
