Kufanele ukwazi lokhu ngesiqandisi esilayishwe efrijini!

Hlobo luni lwamafriji akhona? Eqinisweni, isithwali esijwayelekile sefriji ngamanzi, anezici ezilandelayo:

Okokuqala, intengo yamanzi ishibhile kakhulu.

Njengoba intengo yamanzi ishibhile, kungukukhetha kokuqala kwama-chiller, futhi namanzi kulula kakhulu ukuwathola. Ezindaweni eziningi lapho imithombo yamanzi ingasweleki kakhulu, ukusebenzisa amanzi njengesiqandisi kuyisinqumo esingcono kakhulu.

Ngaphezu kwalokho, njengamanzi abandayo, ukusetshenziswa kwamanzi ngeke kube kukhulu kakhulu. Mayelana nokusetshenziswa kwemali kwebhizinisi jikelele, kungachazwa njengokwehla kwebhakede. Ngakho-ke, ilungele kakhulu noma yisiphi isiqandisi kanye nebhizinisi elidinga ukukhiqiza amafriji angaphezu kuka-0 degrees Celsius.

Okwesibili, ikhwalithi yamanzi iqinisekiswa kalula.

Yize kunemithelela eminingi kwikhwalithi yamanzi, izinga lamanzi empeleni kulula kakhulu ukuliqinisekisa, kufaka phakathi umjovo wamaphilisi ahlanzekile wamanzi, noma ukuhlunga kwamanzi okulula ukuqinisekisa ikhwalithi yamanzi. Amanzi uhlelo olusebenziseka kalula lokupholisa othwala. Umenzeli.

Okwesithathu ukuthi amanzi awanabungozi futhi ayaziqhumane.

Amanzi yisiphathi sefriji esiphephe kakhulu samafriji. Isiqandisi akuyona ukuphela kwohlobo lweFreon. Ngakho-ke, amanzi afriziwe futhi ayi-carrier efrijini, futhi alukho uhlobo olulodwa kuphela. Ngaphezu kwamanzi, kunezinye izinhlobo, njengamanzi anosawoti avame kakhulu, kanye neziphuzo ezifana ne-ethylene glycol, i-methanol noma i-ethanol. Uma nje ungamanzi futhi uhlangabezana nezimpawu nezidingo zamanzi abandayo (isithwali sefriji) sesiqandisi, singasetshenziswa ngokujwayelekile.

Endabeni yamanzi anosawoti, kufanele kusetshenziswe amanzi anosawoti angavamile. Umehluko omkhulu phakathi kwamanzi angenasawoti kasawoti namanzi ukuthi owokuqala angasebenza emazingeni okushisa angaphansi kuka-0 degrees Celsius, kanti amanzi, njengoba sonke sazi, i-0 degrees Celsius iyindawo yawo yokuqandisa. Ibandisiwe ngakho-ke ayikwazi ukusebenza.

Okweziqandisi ezifana ne-ethylene glycol, yize amathuba okusetshenziswa kwayo ephansi uma kuqhathaniswa namanzi, kusenesabelo esithile semakethe. Kodwa-ke, lolu hlobo lwamanzi afriziwe (ifriji) kufanele anake ukuvimbela umlilo nokushisa.
