Muyenera kudziwa izi za firiji yodzaza mufiriji!

Kodi ndimafiriji otani omwe alipo? M’malo mwake, chofala chofala kwambiri ndimadzi, omwe ali ndi izi:

Choyamba, mtengo wamadzi ndi wotsika mtengo kwambiri.

Popeza mtengo wamadzi ndi wotsika mtengo, ndiye chisankho choyamba kwa otentha, ndipo madzi amakhalanso osavuta kupeza. M’madera ambiri momwe madzi samasowa kwambiri, kugwiritsa ntchito madzi ngati firiji ndiye chisankho chabwino kwambiri.

Kuphatikiza apo, monga madzi otentha, kumwa madzi sikudzakhala kwakukulu kwambiri. Malinga ndi momwe ndalama zonse zimagwiritsidwira ntchito, titha kunena kuti ndi dontho. Chifukwa chake, ndioyenera kwambiri kwa firiji ndi bizinesi iliyonse yomwe imayenera kupanga mafiriji pamwamba pa 0 madigiri Celsius.

Chachiwiri, mtundu wamadzi umatsimikizika mosavuta.

Ngakhale pali zambiri zomwe zimakhudza mtundu wamadzi, mtundu wa madzi ndiosavuta kuwatsimikizira, kuphatikiza jakisoni wa mapiritsi amadzi oyera, kapena kusefera kwamadzi kosavuta kuti muwonetsetse kuti madzi ndi abwino. Madzi ndi yosavuta kugwiritsa ntchito chonyamulira dongosolo kuzirala. Mtumiki.

Chachitatu ndichakuti madzi siowopsa komanso amaphulika.

Madzi ndi otetezeka kwambiri osungira mafiriji. The refrigerant si mtundu wokha wa Freon. Chifukwa chake, madzi achisanu amakhalanso chotengera chonyamulira, ndipo palibe mtundu umodzi wokha. Kuphatikiza pa madzi, pali mitundu ina, monga Madzi amchere ambiri, komanso zakumwa monga ethylene glycol, methanol kapena ethanol. Malingana ngati imakhala yamadzi ndipo imakwaniritsa mawonekedwe ndi zofunika za madzi otentha (chotengera cha refrigerant) mufiriji, itha kugwiritsidwa ntchito mwachizolowezi.

Pankhani yamadzi amchere, ayenera kugwiritsidwa ntchito madzi amchere. Kusiyanitsa kwakukulu pakati pa madzi amchere amchere ndi madzi ndikuti akale amatha kugwira ntchito pamazizira ochepera 0 digiri Celsius, pomwe madzi, monga tonse tikudziwa, 0 degrees Celsius ndiye malo ake ozizira. Ndiwowuma motero sungathe kugwira ntchito.

Kwa mafiriji monga ethylene glycol, ngakhale kugwiritsa ntchito kwake kumakhala kotsika poyerekeza ndi madzi, kumakhalabe ndi gawo lina pamsika. Komabe, madzi oundana amtunduwu (refrigerant) ayenera kusamala ndi kupewa moto komanso kuyaka.
