IIziqandisi eziqondilekanti iziqandisi ezivundlile emakethe zisebenzisa ukupholisa umoya, ukuqandisa, njll., kodwa zonke ziyizinhlobo ezahlukene zeziqandisi i-R600A ne-R134A. Vele, "i-catalyst" lapha ibhekisela ekudlulisweni kwamandla, okungukuthi, ukuhwamuka kanye nokufinyela ukuze kufezwe ukudluliselwa kokushisa. Kubantu abavamile, sidinga ukuqonda kuphela ukuthi kuyingxenye ebalulekile yokuqandisa isiqandisi.
Ukuze kube lula ngawe ukuqonda, isimiso esiyisisekelo sokuqandisa sincike ekujikelezeni kweCarnot okuphambene ngezinyathelo ezine ezibalulekile:
(1) Ukucindezela (izinga lokushisa eliphezulu kanye negesi ecindezelekile ephezulu)
I-compressor icindezela igesi efrijini enokushisa okuphansi kanye nokucindezela okuphansi ibe yigesi enokushisa okuphezulu kanye nokucindezela okuphezulu, okwenza izinga lokushisa layo lenyuke kakhulu (isb. kusukela ku--20 ° C kuya ku-100 ° C).
(2) Ukufinyela (ukushabalaliswa kokushisa kuba uketshezi)
Igesi yokushisa ephezulu kanye nomfutho ophezulu ingena kwi-condenser, ikhipha ukushisa ngefeni yokupholisa, bese iphenduka ibe uketshezi lokushisa olujwayelekile kanye nomfutho ophezulu ngemva kokupholisa.
(3) Ukwandiswa (i-endothermic yokufudumeza umoya encishisiwe)
Ngemva kokuba uketshezi olunomfutho ophezulu ludlule ku-valve yokwandisa, umfutho wehla kakhulu, uphefuzele kancane futhi umunce ukushisa okuzungeze i-evaporator, okwenza ingaphakathi lesiqandisi liphole.
(4) Ukuhwamuka (izinga lokushisa eliphansi kanye negesi ephansi yokucindezela)
Uketshezi oluqandisayo olusezingeni lokushisa eliphansi kanye nomfutho luphehlwa ngokuphelele ku-evaporator, lumunce ukushisa okusesiqandisini, bese lubuyela ku-compressor ukuze luqedele umjikelezo.
Kuleli qophelo, indima ebalulekile yesiqandisi ibonakala ekumuncweni kokushisa okushintsha isigaba kanye ne-exotherm, futhi inqubo yokumuncwa kokushisa ngomhwamuko izopholisa isiqandisi.
Qaphela:Isiqandisi siphinde sisetshenziswe ohlelweni oluvaliwe futhi sisetshenziswa ngokuphindaphindiwe ngaphandle kokudliwa. Izakhiwo zaso zomzimba (isb. izinga eliphansi lokubila, ukushisa okuphezulu okucashile) zinquma ukusebenza kahle kokupholisa.
Lapha ngidinga ukukuchazela ukuthi abasebenzisi bangase badide umqondo we-"catalyst" ne-"medium". Ama-refrigerant awahlanganyeli ekusabeleni kwamakhemikhali, kodwa adlulisela amandla ngokushintsha kwesigaba somzimba, kodwa ukusebenza kwawo kuthinta ngqo umphumela wokupholisa (njengokusebenza kahle, izinga lokushisa), njengokubaluleka kwama-catalyst ekusabeleni kwamakhemikhali, kodwa lezi zindlela ezimbili zihlukile ngokuphelele.
Izici:
(1) Kulula ukufudumeza nokudonsa ukushisa ekamelweni lokushisa (isb. i-R600a yokubilisa - 11.7 ° C), izinzile ngamakhemikhali, futhi akulula ukuyibolisa noma ukuyidla imishini.
(2) Ubungane nemvelo: Nciphisa umonakalo ongqimbeni lwe-ozone (isib. i-R134a ithatha indawo ye-R12).
Ama-refrigerant ayindlela eyinhloko yokubanda esiqandisini sezentengiselwano. Adlulisela ukushisa ngokushintsha kwesigaba, okufana “nabathwali bokushisa”, abakhipha ukushisa ngaphakathi esiqandisini ngaphandle ngokujikeleza, ngaleyo ndlela balondoloze indawo ephansi yokushisa.
