Kungani i-CO2 incubator yami inomswakama?
Uma sisebenzisaIsithwali se-CO2Ukuze sihlakulele amaseli, ngenxa yomehluko enanini loketshezi olungeziwe kanye nomjikelezo wokukhuliswa, sinezidingo ezahlukene zomswakama ohlobene ku-incubator.
Ekuhlolweni okusetshenziswa amapuleti okukhulisa amaseli angu-96 anomjikelezo omude wokukhulisa, ngenxa yenani elincane loketshezi olufakwe emthonjeni owodwa, kunengozi yokuthi ikhambi lokukhulisa lizokoma uma lihwamuka isikhathi eside ku-37 ℃.
Umswakama ophezulu ohlobene ku-incubator, isibonelo, ukuze ufinyelele ngaphezu kuka-90%, unganciphisa ngempumelelo ukuhwamuka koketshezi, nokho, kuvele inkinga entsha, ososayensi abaningi besayensi yamasiko amaseli bathole ukuthi i-incubator kulula ukuyikhiqiza ezimweni zomswakama ophezulu, ukukhiqizwa kwe-condensate uma kungalawulwa, kuzoqongelela kakhulu, ukuze isiko lamaseli lilethe ingozi ethile yokutheleleka ngamagciwane.
Ngakho-ke, ingabe ukukhiqizwa kokujiya ku-incubator kungenxa yokuthi umswakama uphezulu kakhulu?
Okokuqala, sidinga ukuqonda umqondo womswakama ohlobene,umswakama ohlobene (Umswakama ohlobene, i-RH)okuqukethwe kwangempela komhwamuko wamanzi emoyeni kanye nephesenti lokuqukethwe komhwamuko wamanzi ekugcwalisweni kokushisa okufanayo. Kuvezwe kule fomula:

iphesenti lomswakama ohlobene limelela isilinganiso sokuqukethwe komhwamuko wamanzi emoyeni nokuqukethwe okuphezulu kakhulu okungenzeka.
Ngokuqondile:
* 0% RH:Akukho mphunga wamanzi emoyeni.
* 100% RH:Umoya ugcwele umhwamuko wamanzi futhi awukwazi ukubamba umhwamuko wamanzi owengeziwe futhi kuzokwenzeka ukujiya.
* 50% RH:Kubonisa ukuthi inani lamanje lomhwamuko wamanzi emoyeni liyingxenye yenani lomhwamuko wamanzi ogcwele kulelo zinga lokushisa. Uma izinga lokushisa lingu-37°C, khona-ke ingcindezi yomhwamuko wamanzi ogcwele icishe ibe ngu-6.27 kPa. Ngakho-ke, ingcindezi yomhwamuko wamanzi kumswakama ongu-50% icishe ibe ngu-3.135 kPa.
Umfutho wamanzi ogcweleingcindezi ekhiqizwa umhwamuko esigabeni segesi lapho amanzi acwebezelayo kanye nomhwamuko wawo kusesilinganisweni esiguquguqukayo ekushiseni okuthile.
Ngokukhethekile, lapho umhwamuko wamanzi namanzi acwebezelayo kuhlangana ndawonye ohlelweni oluvaliwe (isb., i-incubator ye-Radobio CO2 evaliwe kahle), ama-molecule amanzi azoqhubeka nokushintsha kusuka esimweni soketshezi kuya esimweni segesi (ukuhwamuka) ngokuhamba kwesikhathi, kanti nama-molecule amanzi acwebezelayo azoqhubeka nokushintsha abe isimo soketshezi (ukujiya).
Ngesinye isikhathi, amazinga okuhwamuka kanye nokujiya ayalingana, kanti ingcindezi yomhwamuko kulelo phuzu ingcindezi yomhwamuko wamanzi agcwele. Ibonakala ngokuthi
1. ukulingana okuguquguqukayo:lapho amanzi nomhwamuko kuhlangana ndawonye ohlelweni oluvaliwe, ukuhwamuka kanye nokujiya ukuze kufinyelelwe ukulingana, ingcindezi yomhwamuko wamanzi ohlelweni ayisashintshi, ngalesi sikhathi ingcindezi ingumfutho womhwamuko wamanzi ogcwele.
2. ukuncika kwezinga lokushisa:Umfutho womoya ogcwele uyashintsha ngokushisa. Lapho izinga lokushisa likhuphuka, amandla e-kinetic ama-molecule amanzi ayanda, ama-molecule amanzi amaningi angabalekela esigabeni segesi, ngakho-ke umfutho womoya ogcwele uyakhuphuka. Ngokuphambene nalokho, lapho izinga lokushisa lehla, umfutho womoya ogcwele uyancipha.
3. Izici:Umfutho wamanzi agcwele uyisici esibalulekile kuphela, asixhomekile enanini loketshezi, kodwa kuphela ngokushisa.
Ifomula evamile esetshenziselwa ukubala umfutho wamanzi agcwele yi-equation ka-Antoine:
Ngamanzi, i-Antoine constant inamanani ahlukene emazingeni okushisa ahlukene. Isethi evamile yama-constant yile:
* A=8.07131
* B=1730.63
* C=233.426
Leli sethi lama-constant lisebenza ebangeni lokushisa elisukela ku-1°C kuya ku-100°C.
Singasebenzisa la ma-constants ukubala ukuthi ingcindezi yamanzi agcwele ku-37°C ingu-6.27 kPa.
Ngakho-ke, angakanani amanzi asemoyeni kuma-degree Celsius angu-37 (°C) esimweni sokucindezela komhwamuko wamanzi okugcwele?
Ukuze sibale okuqukethwe kwesisindo somswakama wamanzi ogcwele (umswakama ophelele), singasebenzisa ifomula yesibalo sikaClausius-Clapeyron:
Umfutho womhwamuko wamanzi ogcwele: Ku-37°C, umfutho womhwamuko wamanzi ogcwele ungu-6.27 kPa.
Ukuguqula izinga lokushisa libe yi-Kelvin: T=37+273.15=310.15 K
Ukufaka esikhundleni sefomula:

Umphumela otholwe ngokubala cishe u-44.6 g/m³.
Ku-37°C, okuqukethwe komhwamuko wamanzi (umswakama ophelele) ekugcwaleni cishe kungama-44.6 g/m³. Lokhu kusho ukuthi imitha ngayinye yama-cubic yomoya ingabamba amagremu angu-44.6 omhwamuko wamanzi.
I-incubator ye-CO2 engu-180L izophatha cishe amagremu angu-8 kuphela omhwamuko wamanzi.Uma ipani lokufaka umswakama kanye nemikhumbi yokukhulisa igcwele uketshezi, umswakama ohlobene ungafinyelela kalula emazingeni aphezulu, ngisho naseduze namanani omswakama wokugcwala.
Uma umswakama ohlobene ufinyelela ku-100%,umhwamuko wamanzi uqala ukujiya. Kuleli qophelo, inani lomhwamuko wamanzi emoyeni lifinyelela inani eliphezulu elingalibamba ekushiseni kwamanje, okungukuthi ukugcwala. Ukwanda okwengeziwe komhwamuko wamanzi noma ukwehla kwezinga lokushisa kubangela umhwamuko wamanzi ukujiya ube ngamanzi acwebezelayo.
Ukuvunda kungenzeka futhi uma umswakama udlula u-95%,kodwa lokhu kuncike kwezinye izici ezifana nokushisa, inani lomhwamuko wamanzi emoyeni, kanye nokushisa kobuso. Lezi zinto ezithonyayo yilezi ezilandelayo:
1. Ukwehla kwezinga lokushisa:Uma inani lomhwamuko wamanzi emoyeni liseduze nokugcwala, noma yikuphi ukwehla okuncane kwezinga lokushisa noma ukwanda kwenani lomhwamuko wamanzi kungabangela ukujiya. Isibonelo, ukushintshashintsha kwezinga lokushisa ku-incubator kungaholela ekwakhiweni kwe-condensate, ngakho-ke izinga lokushisa lizinzile kakhulu i-incubator izoba nomthelela wokuvimbela ekwakhiweni kwe-condensate.
2. izinga lokushisa lobuso bendawo elingaphansi kwezinga lokushisa lamazolo:izinga lokushisa lobuso bendawo liphansi kunezinga lokushisa lamazolo, umhwamuko wamanzi uzojiya ube amaconsi amanzi kulezi zindawo, ngakho-ke ukufana kwezinga lokushisa kwe-incubator kuzoba nokusebenza okungcono ekuvinjelweni kokujiya.
3. Ukwanda komhwamuko wamanzi:isibonelo, izitsha zokufaka umswakama kanye nezitsha zokukhulisa ezinoketshezi oluningi, kanye ne-incubator zivalwe kangcono, lapho inani lomhwamuko wamanzi emoyeni ngaphakathi kwe-incubator lenyuka ngaphezu komthamo walo omkhulu ekushiseni kwamanje, noma ngabe izinga lokushisa lihlala lingashintshi, kuzokhiqizwa ukuminyana.
Ngakho-ke, i-CO2 incubator enokulawula okuhle kokushisa ngokusobala inomphumela wokuvimbela ekwakhiweni kwe-condensate, kodwa lapho umswakama ohlobene udlula u-95% noma ufinyelela ngisho nokugcwala, amathuba okufiphala azokhula kakhulu,Ngakho-ke, lapho sihlakulela amaseli, ngaphezu kokukhetha i-CO2 incubator enhle, kufanele sizame ukugwema ingozi yokufiphala okubangelwa ukuphishekela umswakama ophezulu.
