IIziqandisi eziqondilekanye neziqandisi ezivundlile emakethe zisebenzisa ukupholisa umoya, isiqandisi, njll., kodwa zonke ziyizinhlobo ezahlukene zeziqandisi u-R600A no-R134A. Yiqiniso, "i-catalyst" lapha ibhekisela ekudlulisweni kwamandla, okungukuthi, i-vaporization kanye ne-condensation ukuze kuzuzwe ukudluliswa kokushisa. Kubantu abavamile, sidinga kuphela ukuqonda ukuthi yingxenye ebalulekile yesiqandisi esiqandisini.
Ukwenza kube lula kuwe ukuqonda, umgomo oyisisekelo wesiqandisi uncike kumjikelezo weCarnot ophambene ngezinyathelo ezine ezibalulekile:
(1) Ukucindezelwa (izinga lokushisa eliphezulu kanye negesi yomfutho ophezulu)
I-compressor icindezela igesi epholile enezinga lokushisa eliphansi kanye ne-low-pressure refrigerant ibe yigesi ephezulu yokushisa kanye ne-high-pressure, okwenza izinga lokushisa layo likhuphuke kakhulu (isb. ukusuka -20 ° C kuya ku-100 ° C).
(2) Ukujiya (ukuncibilika kokushisa kuba uketshezi)
Izinga lokushisa eliphezulu kanye negesi yomfutho ophezulu ingena ku-condenser, ikhiphe ukushisa ngesiphephetha-moya esipholile, bese iphenduka izinga lokushisa elivamile noketshezi olunomfutho ophezulu ngemva kokupholisa.
(3) Ukunwetshwa (i-pressure vaporization endothermic eyehlisiwe)
Ngemva kokuba uketshezi olunomfutho ophezulu ludlule ku-valve yokwandisa, ukucindezela kwehla kakhulu, kuhwamuke kancane futhi kubambe ukushisa okuzungeze i-evaporator, okubangela ukuthi ingaphakathi lesiqandisi liphole.
(4) Ukuhwamuka (izinga lokushisa eliphansi kanye negesi enomfutho ophansi)
Uketshezi oluyisiqandisi ekushiseni okuphansi nokucindezela kuhwamuka ngokuphelele ku-evaporator, kubambe ukushisa esiqandisini, bese kubuyela ku-compressor ukuqedela umjikelezo.
Kuleli qophelo, indima ebalulekile yesiqandisi ibonakala ekushintsheni kwesigaba sokushisa nokukhishwa kwe-exotherm, futhi inqubo yokufaka ukushisa kwe-vaporization izopholisa isiqandisi.
Qaphela:Isiqandisi sigaywa kabusha kusistimu evaliwe futhi sisetshenziswa ngokuphindaphindiwe ngaphandle kokudliwa. Izici zayo ezibonakalayo (isb. indawo ephansi yokubilisa, ukushisa okucashile okuphezulu) kunquma ukusebenza kahle kokupholisa.
Lapha ngidinga ukukuchazela ukuthi abasebenzisi bangase badide umqondo we-“catalyst” nethi “medium”. Iziqandisi azibambi iqhaza ekuphenduleni kwamakhemikhali, kodwa zidlulisela amandla ngezinguquko zesigaba somzimba, kodwa ukusebenza kwazo kuthinta ngokuqondile umphumela wokupholisa (njengokusebenza kahle, izinga lokushisa), njengokubaluleka kwama-catalyst ekuphenduleni kwamakhemikhali, kodwa lezi zindlela ezimbili zihluke ngokuphelele.
Izici:
(1) Kulula ukuhwamuka nokumunca ukushisa ekamelweni lokushisa (isb. R600a indawo abilayo - 11.7 ° C), inokuqina kwamakhemikhali, futhi akulula ukubola noma ukugqwala kwezinto zokusebenza.
(2) Ubungane bemvelo: Yehlisa umonakalo ongqimbeni lwe-ozone (isb. i-R134a ithatha indawo ka-R12).
Iziqandisi ziwumthombo oyinhloko wesiqandisi sokuhweba. Badlulisa ukushisa ngokushintsha kwesigaba, okufana "nabathwali bokushisa", abakhulula ukushisa ngaphakathi kwesiqandisi ngaphandle ngokujikeleza, ngaleyo ndlela kugcinwe indawo yokushisa ephansi.
