Kodi pali kusiyana kotani pakati pa firiji ya mankhwala ndi firiji ya m'nyumba?

Mafiriji a m'nyumba ndi odziwika bwino kwa anthu. Ndiwo zipangizo zapakhomo zomwe zimagwiritsidwa ntchito kwambiri tsiku ndi tsiku. Ngakhale kutimafiriji a mankhwalasizigwiritsidwa ntchito kwambiri ndi mabanja. Nthawi zina mumatha kuwona chitseko chagalasimafiriji a mankhwalam'masitolo ogulitsa mankhwala.mafiriji a mankhwalanthawi zambiri amakhala ndi zitseko zowonekera bwino zagalasi, zowala bwino komanso zopanda chisanu pazitseko kapena kulikonse mkati. Izi zimafotokoza bwino kusiyana pakati pamafiriji a mankhwalandi mafiriji apakhomo. Komabe, ndikufuna kufotokoza kusiyana kwakukulu kwa mafiriji poyerekezera magulu awiriwa a mafiriji.

 

 

 

Kutentha

 

Mankhwala wamba nthawi zambiri amatha kusungidwa kutentha kwa chipinda pakati pa 15°C ndi 25°C (59°F mpaka 77°F), pamalo ozizira komanso ouma, komabe chonde tsatirani malangizo awo osungira.Mafiriji a pharmacyndikofunikira kuti kutentha kukhale pakati pa 2°C ndi 8°C (36°F ndi 46°F). Uwu ndi mtundu wokhazikika wa kutentha womwe umalola kusinthasintha pang'ono chifukwa cha chitseko chomwe chikutsegulidwa. Kukhazikika kwapakati pa 5°C (41°F) ndi lamulo labwino. Mankhwala osungidwa mufiriji sayenera kuzizira.

 

 

Njira Yokhazikitsira Kutentha

 

Thermostat ya digito, yomwe imatchedwanso thermostat yamagetsi, imapereka njira yowongolera kutentha kwa mafiriji molondola kuposa momwe thermostat yamakina imachitira. Mafiriji ena apakhomo amagwiritsanso ntchito thermostat ya digito koma mafiriji azachipatala onse amagwiritsa ntchito ma thermostat a digito. Kuwongolera kutentha koyenera ndikofunikira chifukwa katemera ndi mankhwala amafunika kusungidwa kutentha koyenera, popanda kusiyana kwakukulu. Mafiriji ambiri azachipatala amabweranso ndi chiwonetsero cholondola cha kutentha kwakunja chomwe chimalola anthu kuwona kutentha kwenikweni kwamkati popanda kutsegula firiji. Chiwonetserochi chimatha kuwonetsa kutentha kochepa komanso kwakukulu kwamkati komanso kutentha kwamakono. Mafiriji achipatala amtundu uwu ali ndi deta yolemba kapena chojambulira cha makina chojambulira kutentha.

 

Kuphatikiza apo, kutentha kwawo kumasiyananso. Mafiriji apakhomo amakhala ndi kutentha kovomerezeka, pomwe mafiriji ambiri azachipatala amakhala ndi kutentha kosiyanasiyana komwe kulipo. Izi zimathandiza zinthu zomwe zimafunika kusungidwa kutentha kozizira kwambiri. Mafiriji ozizira nthawi zambiri amaikidwa kutentha monga -20 °C, -40 °C kapena -80 °C. Pomwe mafiriji apakhomo nthawi zambiri amakhala ndi kutentha kotsika kwa -18 °C.

Mpweya wabwino ndi kuyenda kwa mpweya

 

Mafiriji apakhomo amagwiritsa ntchito njira yoziziritsira mwachindunji kapena njira yoziziritsira mpweya. Koma mafiriji azachipatala onse amagwiritsa ntchito njira yoziziritsira mpweya, ndipo ena mwa iwo amagwiritsa ntchito njira yoziziritsira mpweya yolimbikitsidwa. Kuziziritsa mwachindunji kungapangitse kutentha kosagwirizana m'bowo lonse. Chifukwa chake, kuziziritsira mwachindunji si njira yabwino yoziritsira zachipatala. Mu njira yoziziritsira mpweya, mafani ogwira ntchito amathandiza kuchepetsa kutentha msanga chitseko chikatsegulidwa. Mafiriji azachipatala amakondanso kukhala ndi mashelufu a waya omwe amawonjezera kuyenda kwa mpweya, pomwe mafiriji apakhomo amakhala ndi mashelufu agalasi kapena apulasitiki omwe ndi osavuta kuyeretsa koma amatseka mpweya. Ma ducting a mafiriji azachipatala amakonzedwanso kuti kutentha kukhale kofanana, chifukwa amapangidwa kuti kutentha kukhale pafupi momwe angathere mpaka pomwe akukonzekera. Mafiriji apakhomo amakondanso kukhala ndi zitini zouma zomwe, ngakhale zothandiza posungira chakudya, zimatsekanso kuyenda kwa mpweya ndikupanga kutentha kwamdima.

 

Zinthu Zamakina

 

Mafiriji azachipatala nthawi zambiri amakhala ndi zitseko zodzitsekera zokha komanso ma alamu a zitseko omwe amamveka bwino chifukwa kusiya chitseko cha firiji yachipatala chotseguka kungakhale koopsa kwambiri ndipo kumakhudza thanzi la odwala ambiri. Mafiriji a m'nyumba nthawi zambiri samakhala ndi zinthu izi. Ndizachilendonso kuti mafiriji azachipatala azikhala ndi maloko otsekeredwa pazitseko zawo, zomwe ndi zachilendo kwambiri m'mafiriji a m'nyumba, komanso ma pedal otsegulira zitseko. Mafiriji a m'nyumba amakhala ndi mapulagi wamba omwe amatha kuchotsedwa mosavuta m'makoma, pomwe mafiriji azachipatala nthawi zambiri amakhala ndi mapulagi "obiriwira" ndi zingwe zoyendetsera zachipatala kuti magetsi asayende bwino. Mafiriji azachipatala alinso ndi zitseko zapamwamba kwambiri m'zitseko zawo, zomwe zimaletsa kulowa kwa mpweya mkati.
