Mafiriji azachipatala amagwiritsidwa ntchito m'magawo azachipatala ndi asayansi makamaka kuti asunge ndi kusungira ma reagents, zitsanzo zamoyo, ndi mankhwala. Chifukwa cha katemerayu, akuchulukirachulukira padziko lonse lapansi, akuchulukirachulukira.
Pali zinthu zosiyanasiyana ndi zosankha zomwe zikupezekamafiriji azachipatalaKutengera ndi nthawi zosiyanasiyana zogwiritsira ntchito, Magawo ambiri opangidwa ndi cholinga amagawidwa m'magulu asanu:
Kusungira Katemera
Zipangizo Zamankhwala
Banki Yosungira Magazi
Laboratory
Chromatography
Kusankha firiji yoyenera yachipatala kwayamba kukhala kofunika kwambiri. Pali zinthu zingapo zofunika posankha firiji yoyenera yachipatala.
Kukula kwa Firiji
Kupeza kukula koyenera ndi gawo lofunika kwambiri pakusankha. Ngati chipinda choziziritsira chachipatala chili chachikulu kwambiri, zidzakhala zovuta kusunga kutentha kwa mkati mkati mwa malo ake ofunikira. Chifukwa chake, ndi bwino kuyang'ana chinthu chomwe chingakwaniritse zosowa zosungira. Kumbali ina, zipinda zomwe ndi zazing'ono kwambiri pa zosowa zosungira zingayambitse kuchulukana kwa anthu komanso mpweya woipa wamkati - zomwe zingapangitse kuti zinthu zina zilowe kumbuyo kwa chipindacho, ndikufooketsa mphamvu ya katemera kapena zitsanzo zina mkati.
Nthawi zonse ganizirani kuchuluka kwa zinthu zomwe zidzasungidwe mufiriji iliyonse yachipatala. Ngati n'kotheka, yesani kuganizira kusintha komwe kungachitike pakusungirako, kuti mukonzekere.
Malo Osungiramo Firiji
Zingamveke ngati zokayikitsa koma malo oikamo ndi chinthu chofunikira kuganizira, chifukwa malo oikamo adzasankha ngati chipangizocho chidzamangidwa mkati, kapena chokhazikika.
Pa malo okhala ndi malo ochepa, tikulimbikitsidwa kugwiritsa ntchito mayunitsi ang'onoang'ono, chifukwa amatha kulowa mosavuta mkati kapena pansi pa ma countertop ambiri; pomwe firiji yayikulu komanso yoyimirira ndi yoyenera bwino malo ogwirira ntchito omwe safunika kusunga malo pansi. Kupatula izi, ndikofunikiranso kuonetsetsa kuti pali malo okwanira ozungulira chipangizocho kuti mpweya uziyenda bwino - pafupifupi mainchesi awiri kapena anayi mbali zonse. Chipangizocho chingafunikenso kuyikidwa m'chipinda china komwe chingasungidwe bwino kuti chisawonongeke ndi kutentha kosiyanasiyana masana.
Kusinthasintha kwa Kutentha
Mfundo ina yofunika yomwe imasiyanitsa firiji yachipatala ndi firiji yapakhomo ndi kuthekera kwake kulamulira kutentha kolondola. Pali kutentha kofanana kwa +/-1.5°C. Zipangizo zoziziritsira zachipatala zimapangidwa kuti zitsimikizire kuti zitsanzo ndi zinthu zachipatala zimasungidwa mkati mwa kutentha kwina kuti zikhalebe ndi moyo. Tili ndi kutentha kosiyana kotsatiraku m'magulu osiyanasiyana.

Mwachitsanzo,firiji ya katemeraNthawi zambiri kutentha kumasunga kutentha pakati pa +2°C mpaka +8°C (+35.6°F mpaka +46.4°F). Kusintha kwa kutentha kungakhudze mphamvu zawo kapena kuwononga kafukufuku yemwe adatenga khama lalikulu komanso ndalama zambiri. Kuwongolera kutentha kosakhazikika kungatanthauzenso kutayika kwa magazi m'mabanki amagazi komanso kusowa kwa mankhwala ofunikira kuzipatala ndi zipatala, pomwe mabungwe ofufuza angasankhe mafiriji omwe angasunge zitsanzo m'mikhalidwe yodziwika bwino. Kwenikweni, mayunitsi apadera oziziritsira azachipatala angagwiritsidwe ntchito pazinthu zosiyanasiyana, bola ngati ntchito zawo zikugwirizana ndi zosowa za malo.
Dongosolo Lowunikira Kutentha kwa Digito
Kusunga kutentha ndi chinthu china chofunikira kwambiri pakusunga zitsanzo zachipatala ndi katemera bwino nthawi zonse.
Bungwe la Centers for Disease Control (CDC) limalimbikitsa kugula zipangizo zoziziritsira kutentha zomwe zili ndi Temperature Monitoring Devices (TMD) ndi Digital Data Loggers (DDL) zomwe zingathandize ogwiritsa ntchito kutsatira ndikusonkhanitsa deta ya kutentha kwamkati popanda kutsegula chitseko. Kuti kuyang'anira kutentha kwa digito, makina a alamu, ndi kusungira deta zikhale zinthu zofunika kwambiri pa mafiriji azachipatala.
Mashelufu
Zipangizo zonse zoyezera matenda zimafuna malo osungira mpweya omwe amalimbikitsa kuyenda bwino kwa mpweya. Ndikoyenera kusankha mafiriji azachipatala okhala ndi mashelufu omangidwa mkati kapena osinthika mosavuta kuti zitsimikizire kuti chipangizocho chikhoza kusunga zinthu zokwanira popanda kudzaza kwambiri. Payenera kukhala malo okwanira pakati pa botolo lililonse la katemera ndi chitsanzo chachilengedwe kuti mpweya uziyenda bwino.
Mafiriji athu ali ndi mashelufu apamwamba kwambiri opangidwa ndi waya wachitsulo wokutidwa ndi PVC wokhala ndi makadi olembera ndi zizindikiro zogawa, zomwe ndizosavuta kuyeretsa.
Chitetezo:
M'malo ambiri, zinthu zamtengo wapatali zimasungidwa mufiriji yachipatala. Chifukwa chake ndikofunikira kukhala ndi chipangizo chomwe chimabwera ndi loko yotetezeka - kiyibodi kapena loko yophatikizana. Kumbali ina, iyenera kukhala ndi makina abwino kwambiri omveka komanso owoneka bwino, mwachitsanzo, kutentha kwambiri ndi kotsika, cholakwika cha sensa, kulephera kwa magetsi, batire yochepa, kutsegula chitseko, cholakwika cholumikizirana ndi mainboard kutentha kwakukulu, zitsanzo zakale, ndi zina zotero; Kuchedwa kuyamba kwa compressor komanso chitetezo choyimitsa nthawi zitha kuonetsetsa kuti ntchito ikuyenda bwino. Chowongolera chophimba chokhudza ndi chowongolera kiyibodi chili ndi chitetezo cha mawu achinsinsi chomwe chingalepheretse kusintha kulikonse kwa ntchito popanda chilolezo.
Zina zomwe muyenera kuganizira:
Dongosolo Losungunula: Dongosolo losungunula la chipangizo choziziritsira chachipatala si chinthu choyenera kunyalanyazidwa. Kusungunula firiji ndi manja kudzatenga nthawi, koma ndikofunikira pa ntchito zinazake ndi zofunikira. Kapenanso, zipangizo zosungunula zokha zimafuna kusamaliridwa kochepa komanso nthawi yochepa koma zimadya mphamvu zambiri kuposa zipangizo zoziziritsira pamanja.
Zitseko za Galasi ndi Zitseko Zolimba: Izi zidzakhala nkhani yofunika kwambiri pakati pa chitetezo ndi mawonekedwe. Mafiriji azachipatala okhala ndi zitseko zagalasi adzakhala othandiza, makamaka pamene wogwiritsa ntchito amafunika kuyang'ana mkati mwachangu osatulutsa mpweya wozizira; pomwe zitseko zolimba zimapereka chitetezo chowonjezera. Zosankha zambiri pano zidzadalira mtundu wa malo azaumoyo omwe chipangizocho chidzagwiritsidwe ntchito.
Zitseko Zodzitsekera: Zipangizo zodzitsekera zokha zimathandiza kuti zipangizo zoziziritsira m'zipatala zisasokoneze kutentha nthawi zonse.
Kusankha firiji yachipatala yoti mugule kumadalira makamaka cholinga chomwe chikuyembekezeka cha chipangizocho. Ndikofunikanso kumvetsetsa kuti kusankha chitsanzo sikungotengera zosowa za malo antchito komanso zosowa zamtsogolo. Palibe vuto poyembekezera zinthu zamtsogolo. Kuti musankhe bwino tsopano, ganizirani momwe zinthu zonsezi zingakhudzire pazaka zomwe firiji yachipatala idzagwiritsidwe ntchito.
