Firiji ndi njira yotseguka yomwe imatulutsa kutentha kuchokera kumalo otsekedwa kupita kumalo otentha, kawirikawiri khitchini kapena chipinda china.Pochotsa kutentha m'derali, kutentha kumachepa, zomwe zimapangitsa kuti chakudya ndi zinthu zina zikhalebe pamalo ozizira.Mafiriji amawoneka kuti akuphwanya Lamulo Lachiwiri la Thermodynamics, koma chifukwa chachikulu chomwe samachitira ndi chifukwa cha ntchito yofunikira monga kulowetsa ku dongosolo.Iwo kwenikweni ndi mapampu kutentha, koma ntchito kuziziritsa dera m'malo kutentha izo.
Momwe amagwirira ntchito
Malinga ndi Lamulo Lachiwiri la Thermodynamics, kutentha kumangoyenda zokha kuchokera kotentha kupita kuzizira, osati mwanjira ina.Firiji imapangitsa kutentha kutuluka kuchokera kuzizira kupita ku otentha polowetsa ntchito, zomwe zimaziziritsa malo mkati mwa furiji.Imachita izi potsatira njira zomwe zili pansipa, zomwe zitha kuwoneka mothandizidwa ndi Chithunzi 1:
Ntchito imalowetsedwa (Win) yomwe imakanikiza choziziritsira, kukulitsa kutentha kwake kuposa kutentha kwachipindacho.
Kutentha kumayenda kuchokera ku chozizirira ichi kupita ku mpweya wa m'chipinda (QH), kumachepetsa kutentha kwa choziziritsira.
Choziziriracho chimakula, ndipo chimazizira pansi pa kutentha mkati mwa furiji.
Kutentha kumayenda kuchokera mufiriji kupita ku ozizira (QC), kuchepetsa kutentha mkati.
Njirayi ndi yozungulira, ndipo imalola mafiriji kuti aziyendetsedwa kwa nthawi yayitali ngati pakufunika.Ntchito yofunikira pa dongosolo imaperekedwa ndi equation
Kupambana=QH−QC
ndi zosintha zomwe zikuwonetsedwa mu Chithunzi 1. Kufanana uku kukuwonetsa kuti firiji iyenera kutulutsa kutentha kwambiri kuchipinda kuposa momwe imachotsera mkati.Izi zimakhala ndi tanthauzo lalikulu ngati mungathe kuziziritsa chipinda posiya chitseko cha firiji chitseguke kapena ayi.
Kuchita bwino
Kuchita bwino kwa firiji kwayenda bwino kwambiri m'zaka zapitazi.Masiku ano mafiriji aku US amadya zosakwana 500 kWh / chaka, zocheperapo kuposa 1800 kWh mu 1972. Kuwongolera kunapangidwa ndikupitilizabe kupangidwa mu kutchinjiriza, kugwiritsa ntchito kompresa, kusinthanitsa kutentha mu evaporator ndi condenser, mafani, ndi zigawo zina za firiji.
Mafiriji otsimikiziridwa ndi US Energy Star ayenera kugwiritsa ntchito magetsi ochepera 20% kuposa muyezo wocheperako waku US wamafiriji.Pali chowerengera (chomwe chingapezeke apa) chomwe chimakulolani kuti muwerengere ndalama zapachaka kuchokera ku furiji yovomerezeka ya Energy star, poyerekeza ndi chitsanzo chomwe muli nacho, kutengera zomwe mumalipira magetsi.
Coefficient of performance (Kuchita bwino)
nkhani yaikulu
Kwa firiji, wopanga angafune kuti malowo azikhala ozizira pomwe akugwira ntchito yochepa momwe angathere.Pochita ntchito yochepa yoziziritsira chipangizocho, firiji ikhoza kukhala pa kutentha komwe ikufunidwa pamene ikugwiritsa ntchito magetsi ochepa, motero, kupulumutsa mwiniwake ndalama.Nambala yomwe ikufotokoza lingaliro ili ndi coefficient of performance, K, yomwe kwenikweni ndi muyeso wa magwiridwe antchito.Equation kwa izo ndi
K=QCWin
Kukwera mtengo uku kumakhala bwino, chifukwa zikutanthauza kuti ntchito yochepa ikuchitika kuti muziziritsa firiji.
Monga mukuwonera Kampani yathu ya AirBrisk ili ndi zida zamakono zopanga ndi satifiketi.Mutha kutipatsa chidaliro chanu.Simuyenera kuda nkhawa ndi vuto lazinthu zathu.Monga mphamvu zogwiritsira ntchito gasi zipangizo ndi zina zotero.Satifiketi yathu inali itawonetsa mphamvu za kampani yathu.
Chifukwa chake timapanga mafiriji amitundu yambiri.Dzuwa ngati firiji ya khomo limodzi, firiji ya pamwamba pazitseko ziwiri, firiji yapansi pazitseko ziwiri ndi firiji ya zitseko zambiri.
Pali mitundu yambiri ya firiji yomwe mungagule posankha.Chifukwa chake musazengereze chitanipo kanthu titumizireni funso lanu tsopano.Ngati muli ndi funso lokhudza mankhwala athu.Mutha kulumikizana nafe patsamba lathu lakampani.Tidzapereka yankho lokwanira munthawi yake.
