Kodi firiji mufiriji ndi chiyani?

Ambiri aife timaona mafiriji ngati chinthu chosavuta. Timaganiza kuti tikafuna chakumwa chozizira kapena ayisikilimu, timangotsegula firiji kapena firiji ndikudzithandiza tokha. Komabe, pankhani ya mafiriji amalonda, mwina mumaona kuti ndi ofunika kwambiri. Mumadalira kuti azisunga chakudya pamalo otentha kuti ateteze makasitomala anu ku matenda.

Koma kodi munayamba mwadzifunsapo kuti mafiriji ndi mafiriji anu amagwira ntchito bwanji? Amadalira chinthu chotchedwa refrigerant kuti aziziziritsa. Pano, tifotokoza momwe mafiriji omwe ali mufiriji ndi mafiriji amagwirira ntchito.

Kodi firiji ndi chiyani?

Kawirikawiri amatchedwa molakwika kuti Freon, refrigerant ndi chinthu chomwe chimagwiritsidwa ntchito kuziziritsa zipangizo, kuphatikizapo mafiriji, mafiriji onyamulika, ma air conditioner, ma heat pump, ndi zina zambiri. Freon ndi dzina la kampani, kotero sikutanthauza kuti imagwira ntchito pa ma refrigerant onse. Ngati firiji yanu siikusunga chakudya chanu chozizira, n'zotheka kuti refrigerant iyenera kudzazidwanso.

Mafiriji amayamwa kutentha ndikusiya mpweya wozizira kudzera mu njira ya thermodynamic yomwe imasintha nthawi zonse firiji kuchoka pamadzimadzi kupita ku mpweya ndikubwerera kumadzimadzi. Mafiriji ambiri omwe ali ndi ma hydrofluorocarbons (HFC) nthawi zambiri sakhala oteteza chilengedwe, pomwe mafiriji omwe ali ndi ma hydrocarbons amaonedwa kuti ndi abwino kwambiri pa chilengedwe.

N’chifukwa chiyani kuli kofunika kwambiri kusunga chakudya chozizira?

Kutentha kozizira kumachepetsa chiopsezo cha mabakiteriya oopsa kukula. Kumachepetsa liwiro la mabakiteriya kuberekana, zomwe zimathandiza kuti chakudya chikhale chotetezeka kwa nthawi yayitali. Mafiriji amasunga chakudya chozizira mwa kusamutsa kutentha nthawi zonse kuchokera m'zipinda. Chinthu chachikulu chomwe chimasunga chakudya chonse chozizira ndi refrigerant.

Kufalikira kwa Magazi ndi Kutuluka kwa Nthunzi

Mafiriji amazungulira firiji kuti kutentha kukhale kochepa. Popeza mpweya wofunda umalowetsedwa nthawi zonse chitseko chikatsegulidwa, firiji imafunika kuti itenge ndikuchotsa mpweya wofunda. Kuyenda kwa mpweya kumafunika kuti firiji isinthe kuchoka pamadzi kupita ku mpweya kuti ithandize kuyendetsa kutentha kudzera mu ndondomeko ya nthunzi. Chinachake chikaphwa, chimayambitsa kuzizira.

Mwachitsanzo. Ichi ndichifukwa chake timatuluka thukuta, Tikatentha kwambiri, timatuluka thukuta, ndipo kutuluka kwa thukuta kumathandiza kuziziritsa thupi. Pa mafiriji ndi mafiriji, kuti tiyambe njirayi, kuthamanga kwa refrigerant kumachepa. Izi zimayendetsedwa ndi chotulutsira chotchedwa capillary chubu. Ngati izi n'zovuta kuziganizira, ganizirani zomwe zimachitika mukagwiritsa ntchito mankhwala a aerosol monga chotsitsimutsa mpweya. Mukakankhira nsonga ya kupopera, imatulutsa zomwe zili mkati mwake pamalo otseguka opanda mphamvu, zomwe zimasintha kuchoka pamadzimadzi kupita ku mpweya, zomwe zimapangitsa kuti zomwe zili mkati mwake zituluke.

Kupsinjika

Popeza kuziziritsa kumadalira kusintha kumeneku kuchoka pamadzi kupita ku mpweya, firiji yanu iyenera kusintha madzi kukhala mpweya nthawi zonse kenako mpweya kubwerera kukhala madzi. Izi zimafuna kupsinjika kuti mpweyawo ukhale wotentha kwambiri komanso wopanikizika. Compressor ya firiji imagwira ntchito ngati pampu ya njinga, ndikupanga kutentha pamene ikupompa ndi kupondereza mpweya.

Pamene compressor ikugwira ntchito bwino, mpweya umakhala ndi mphamvu zambiri ndipo umatenthanso. Choncho popeza tsopano yatentha, condenser iyenera kuziziritsa kuti isinthe kukhala madzi. Refrigerant imatha kubwerera ku evaporator ngati madzi kotero kuti njirayi imayambanso.

Zogulitsa za Colku zokhala ndi Refrigerant

Ambiri mwa ma colku denga la galimotondi firiji yagalimotoGwiritsani ntchito ma refrigerant awiri, R134a ndi R410a, omwe ndi zinthu za HFC, kotero sawononga ozone layer ndipo ndi ma refrigerant abwino kwambiri. Ndi ma refrigerant abwino kwambiri omwe amadziwika ndi kuvomerezedwa ndi mayiko ambiri padziko lonse lapansi. Ngati mukufuna, tithanso kupereka zofunikira. satifiketipa mitundu ya zinthu zovomerezeka. Chifukwa chake mukagula colku's zoziziritsa mpweya za galimotondi mafiriji a magalimoto, simuyenera kuda nkhawa kuti mabungwe oteteza zachilengedwe akumaloko angakulangizeni kugwiritsa ntchito ma refrigerant osayenerera.

Ngati mukufuna ma air conditioner a galimoto ya colku ndi mafiriji a magalimoto, Dinani kuti mulumikizane nafe.
