Ubuchwepheshe Besiqandisi Ngezinhlelo Zokupholisa Ezisekelwe ku-Freon vs. Ezingezona Ezisekelwe ku-Freon
Ubuchwepheshe bokuqandisa, ikakhulukazi iziqandisi, sebuyingxenye ebalulekile yempilo yanamuhla. Ngokuhamba kwesikhathi, izinhlelo zokupholisa nazo ziye zashintsha kakhulu, ikakhulukazi ngokwezinto ezisetshenziswa enkambisweni yokupholisa. Ubuchwepheshe obubili obuvame ukuqhathaniswa izinhlelo zokupholisa ezisekelwe ku-freon kanye nezinhlelo zokupholisa ezisekelwe ku-freon. Lesi sihloko sizoxoxa ngobuchwepheshe bobabili ngokujulile, sihlanganisa izimiso zabo zokusebenza, izinzuzo kanye nokungalungi, kanye nomthelela wemvelo walobu buchwepheshe.
Indlela Amafriji Asekelwe Ku-Freon Asebenza Ngayo
I-Freon igama lophawu lokuhweba lezinhlobo eziningi zeziqandisi ezakhiwe yinkampani iDuPont. Lawa makhemikhali angomndeni we-chlorofluorocarbon (CFC) kanye ne-hydrochlorofluorocarbon (HCFC), futhi asetshenziswa kabanzi ezinhlotsheni ezahlukene zezicelo zeziqandisi, okuhlanganisa neziqandisi.
Isimiso sokusebenza sesiqandisi esisekelwe ku-Freon sifana nesimiso sokupholisa esivamile. I-Freon isetshenziswa njengoketshezi olusebenzayo, olugeleza ezingxenyeni ezahlukene ezifana ne-compressor, i-condenser, i-expansion valve, kanye ne-evaporator. Nazi izinyathelo ezihilelekile:
1. Ukucindezela: I-Freon ngesimo segesi icindezelwa yi-compressor ukuze izinga lokushisa layo likhuphuke.
2. Ukujiya: Igesi eshisayo ye-freon ibe isidluliswa nge-condenser. Lapha, igesi ikhipha ukushisa endaweni ezungezile bese iphenduka uketshezi.
3. Ukwanda: Uketshezi lwe-freon ludlula nge-valve yokwandisa, ekhipha ingcindezi futhi ibangele ukuthi i-freon ikhule futhi iphole.
4. Ukuhwamuka: Uketshezi olubandayo lwe-freon lugeleza nge-evaporator, lumunce ukushisa okuvela ngaphakathi esiqandisini, lwehlise izinga lokushisa ngaphakathi. I-freon ibuyela kugesi, bese umjikelezo uphinda.
Izinzuzo zeSistimu ye-Freon:
1. Ukusebenza Kokupholisa: I-Freon inamandla okupholisa amahle kakhulu, ikwazi ukufinyelela amazinga okushisa aphansi ngokushesha.
2. Ukuzinza Kwamakhemikhali: I-Freon izinzile ngamakhemikhali, ngakho-ke impilo yayo yokusebenza inde impela.
3. Umklamo Omncane: Amadivayisi anezinhlelo ze-freon ngokuvamile ancane kakhulu, okwenza abe usizo kakhulu ekusetshenzisweni ekhaya.
Izinkinga zesistimu ye-Freon:
1. Umthelela Wezemvelo: I-Freon, ikakhulukazi izinhlobo ze-CFC kanye ne-HCFC, inamandla okulimaza ungqimba lwe-ozone futhi ifake isandla emphumela wokushisa komhlaba.
2. Umthetho Oqinile: Ukusetshenziswa kwe-freon manje kulawulwa ngokuqinile yizinhlangano ezahlukahlukene zomhlaba wonke ngenxa yethonya layo emvelweni, ngakho-ke ukukhiqizwa nokusatshalaliswa kwayo kungaphazamiseka.
3. Izindleko Zokuphatha: Izinhlelo ze-Freon zidinga ukulungiswa nokuphathwa ngokucophelela ukuze kuvinjelwe ukuvuza okungalimaza imvelo.
Indlela Isiqandisi Esingenawo Ama-Freeon Esisebenza Ngayo
Njengoba ulwazi olukhulayo ngokubaluleka kokuvikelwa kwemvelo lukhula, kuye kwavela ezinye izindlela zokupholisa ezingezona eze-Freon ezingasebenzisi imvelo. Lokhu kufaka phakathi ama-hydrocarbon afana ne-isobutane (R-600a) kanye ne-propane (R-290), kanye nama-hydrofluorocarbon (HFCs) afana ne-R-134a.
Empeleni, isiqandisi esingeyona i-Freon sisebenza cishe ngendlela efanayo nesiqandisi esisekelwe ku-Freon, kanti umehluko omkhulu uwuhlobo lwesiqandisi esisetshenziswayo. Ake sibheke izimiso nezibonelo zesiqandisi esingeyona i-Freon.
Izibonelo zamafriji angewona ama-Freeon:
1. Ama-hydrocarbon (HC): Amafriji asebenzisa ama-hydrocarbon afana ne-isobutane (R-600a) kanye ne-propane (R-290) aziwa ngokuba nobungane kakhulu nemvelo. Lezi zinto azilimazi ungqimba lwe-ozone futhi zinamandla aphansi okushisa komhlaba.
2. Ama-hydrofluorocarbon (ama-HFC): I-R-134a iyi-refrigerant ye-HFC esetshenziswa kakhulu. Nakuba ingawuqedi ungqimba lwe-ozone, amandla ayo okufudumala komhlaba asephezulu kakhulu, ngakho-ke kusenendawo yokuthuthukiswa kwama-refrigerant anobungani nemvelo.
3. I-Ammonia (NH3): I-Ammonia ivame ukusetshenziswa ezinhlelweni zokupholisa zezimboni futhi isiqala ukusetshenziswa eziqandisini zasekhaya. I-Ammonia ayiqedi ungqimba lwe-ozone, kodwa iyagqwala futhi inobuthi uma ivuza, idinga ukuphathwa ngokucophelela.
Izinzuzo Zezinhlelo Ezingezona Ezamahhala:
1. Okunobungani Nemvelo: Ama-refrigerant amaningi angewona ama-freon awawonakalisi ungqimba lwe-ozone futhi anamandla okushisa komhlaba aphansi kakhulu.
2. Ukuthobela Imithetho: Ukusetshenziswa kweziqandisi ezingezona ezikhululekile ngokuvamile kulula ukuziqapha nokuzilawula ngenxa yomthelela wazo omncane kwezemvelo.
3. Ukusungula Izinto Ezintsha Kwezobuchwepheshe: Izinkampani eziningi manje sezigxile ekuthuthukisweni kweziqandisi ezingezona ezivamile ukuze ubuchwepheshe kule ndawo buthuthuke ngokushesha futhi bunikeze ezinye izixazululo ezisebenzayo.
Okubi Ngezinhlelo Ezingezona Ezikhululekile:
1. Izindleko Zokuqala Eziphezulu: Ezinye izinhlelo zokupholisa ezingezona eze-freon zidinga ukutshalwa kwezimali kokuqala okuphezulu kocwaningo nokuthuthukiswa kanye nokusetshenziswa kobuchwepheshe obusha.
2. Izinkinga Zokuphepha: Ezinye iziqandisi ezingezona i-freon, njenge-hydrocarbon, ziyavutha, kanti i-ammonia iyagqwala. Lokhu kudinga izinhlelo zokuphepha ezengeziwe.
3. Ukusebenza Kahle Nokuhambisana: Amanye amafriji angewona ama-freon angase angasebenzi kahle njenge-freon ngaphansi kwezimo ezithile, noma adinge izinguquko zomklamo ezinhlelweni zokupholisa ezikhona.
Umthelela Wezemvelo
Izinkinga zemvelo zivame ukuba yimbangela ebalulekile yoshintsho kwezobuchwepheshe. Iziqandisi ezisekelwe ku-freon ziboniswe zinemiphumela emibi kakhulu emvelweni, ikakhulukazi ungqimba lwe-ozone kanye nesimo sezulu somhlaba wonke.
Ama-Freon, ikakhulukazi ama-CFC, ahlotshaniswa nokubhujiswa kongqimba lwe-ozone, oluvikela uMhlaba emisebeni ye-ultraviolet eningi kakhulu. Ama-HCFC, nakuba engawonakalisi kangako kune-CFC, asenemiphumela emibi. Iziqandisi ze-HFC ezifana ne-R-134a, nakuba zinganciphisi i-ozone, zinamandla amakhulu okufudumala komhlaba (i-GWP), okungabhebhethekisa ushintsho lwesimo sezulu.
Njengoba ulwazi oluningi ngezinkinga zemvelo lukhula, izinketho eziningi ze-non-freon refrigerant ezinobungani nemvelo ziya ngokuya zikhanga. Ama-hydrocarbon afana ne-isobutane ne-propane ane-GWP ephansi kakhulu futhi awanciphisi i-ozone. Kodwa-ke, ukuphepha kusalokhu kuyinto ebalulekile lapho uwasebenzisa. Ngokufanayo, i-ammonia, nakuba ingaba yingozi uma ivuza, ine-GWP ephansi kanye nokusebenza kahle okuphezulu.
Ikusasa Lobuchwepheshe Bokupholisa
Njengoba kucatshangelwa ukukhathazeka okukhulu ngezemvelo, ucwaningo kanye nokusungula izinto ezintsha kwezobuchwepheshe bokuqandisa kuyaqhubeka. Ukuthuthukiswa kwamafriji amasha asebenza kahle futhi anobungani nemvelo kuyinto ebalulekile ezikhungweni eziningi zocwaningo kanye nezinkampani zobuchwepheshe.
Kwenziwa nemizamo eqhubekayo yokuthuthukisa ukusebenza kahle kwamandla kwezinhlelo zokupholisa, okunganciphisa ukukhishwa kwe-carbon dioxide ngenxa yokusetshenziswa kukagesi. Ukusetshenziswa kwemithombo yamandla avuselelekayo kanye nokufakwa kokushisa okuthuthukisiwe nakho kungaba yingxenye yezixazululo zesikhathi esizayo.
Isiphetho
Ubuchwepheshe besiqandisi obunezinhlelo zokupholisa ezisekelwe ku-freon kanye nezinhlelo ezingezona ezisekelwe ku-freon bunezinzuzo nezinkinga zabo. Nakuba i-freon inikeza ukusebenza kahle nokuzinza, umthelela wayo emvelweni uye wanciphisa ukusetshenziswa kwayo. Ngakolunye uhlangothi, ubuchwepheshe obungezona ezisekelwe ku-freon, ngenkathi bubhekene nezinselele ezinkingeni zokuqala zezindleko nokuphepha, bunikeza ikhambi elinobungani nemvelo.
Ukukhetha phakathi kwama-refrigerant e-freon kanye nama-non-freon kuqhutshwa yintuthuko eyengeziwe kulo mkhakha kanye nokusetshenziswa kwezinqubomgomo eziqinile zemvelo. Ucwaningo nentuthuko kuyaqhubeka ukuthola i-refrigerant efanele ehlangabezana nezidingo zokupholisa ngaphandle kokulimaza imvelo. Ukushintshela kubuchwepheshe obuhlanzekile nobunobungani nemvelo akugcini nje ngokuphendula ezidingweni zamanje kodwa futhi nokutshalwa kwezimali ekusimeni okuzayo kweplanethi.
