Umehluko Phakathi Kwesiqandisi Nesiqandisi (Kuchaziwe)

Ukupholisa nesiqandisi kuyindaba ehluke kakhulu. Umehluko wabo mkhulu. Isipholisa ngokuvamile sisetshenziswa ohlelweni lokupholisa. Isiqandisi ngokuvamile sisetshenziswa ohlelweni lwesiqandisi. Thatha isibonelo esilula, uma unemoto yesimanje ene-air conditioner, ufaka isiqandisi ku-compressor ye-air conditioner; engeza into epholile ethangini lokupholisa labalandeli.

Incazelo ye-coolant

Isipholisi siyinto, ngokuvamile ewuketshezi, esetshenziselwa ukunciphisa noma ukulawula izinga lokushisa lesistimu. Isipholile esikahle sinamandla okushisa aphezulu, i-viscosity ephansi, sinezindleko eziphansi, asinabuthi, asizinzi ngamakhemikhali futhi asibangeli noma sikhuthaze ukugqwala kwesistimu yokupholisa. Ezinye izinhlelo zokusebenza nazo zidinga ukuthi isipholile sibe isivikelo sikagesi.

Incazelo yesiqandisi

Isiqandisi siwuketshezi olusebenzayo olusetshenziswa emjikelezweni wesiqandisi wezinhlelo zokupholisa umoya kanye namaphampu okushisa lapho ezimweni eziningi beshintshana ngokuphindaphindiwe kwesigaba besuka oketshezini baye egesini bese bebuyela emuva futhi. Iziqandisi zilawulwa kakhulu ngenxa yobuthi bazo, ukuvutha kanye negalelo leziqandisi ze-CFC ne-HCFC ekucekeleni phansi kwe-ozone kanye neziqandisi ze-HFC ekushintsheni kwesimo sezulu.
