I.Izicelo:
Idivayisi yokuhlola ukucindezeleka kwemvelo isetshenziselwa ikakhulukazi ukuthola isenzakalo sokuqhekeka nokubhujiswa kwezinto ezingezona ezensimbi ezifana namapulasitiki kanye nerabha ngaphansi kwesenzo sesikhathi eside sokucindezeleka ngaphansi kwephuzu layo lokukhiqiza. Ikhono lezinto zokumelana nokulimala kokucindezeleka kwemvelo liyalinganiswa. Lo mkhiqizo usetshenziswa kakhulu kumapulasitiki, irabha nezinye izinto zokwakha ze-polymer, ucwaningo, ukuhlola nezinye izimboni. Ibhavu ye-thermostatic yalo mkhiqizo ingasetshenziswa njengesisetshenziswa sokuhlola esizimele ukuze kulungiswe isimo noma izinga lokushisa lamasampula okuhlola ahlukahlukene.
