Iziqandisi

Ama-HVAC, ama-Refrigerator nama-air conditioner avame ukusetshenziswa emadolobheni amaningi, emakhaya nasezimotweni. Ama-Refrigerator nama-air conditioner enza ingxenye enkulu yokuthengiswa kwemishini yasekhaya. Inani lama-refrigerator nama-air conditioner emhlabeni liyinani elikhulu. Isizathu sokuthi ama-refrigerator nama-air conditioner angaphola kungenxa yengxenye eyinhloko, i-compressor. I-compressor isebenzisa i-refrigerant ukuthutha amandla okushisa ngesikhathi sokusebenza. Ama-refrigerator anezinhlobo eziningi. Amanye ama-refrigerator avamile asetshenziswa kusukela kudala alimaza ungqimba lwe-ozone futhi athinta ukufudumala komhlaba. Ngakho-ke, ohulumeni nezinhlangano balawula ukusetshenziswa kwama-refrigerator ahlukene.

 

Isivumelwano saseMontreal

Isivumelwano saseMontreal siyisivumelwano somhlaba wonke sokuvikela ungqimba lwe-ozone loMhlaba ngokuqeda amakhemikhali aluqeda. Ngo-2007, i-The Decision XIX/6 edumile, eyathathwa ngo-2007, ukulungisa i-Protocol ukuze kusheshiswe isigaba sokuphuma kwama-Hydrochlorofluorocarbons noma ama-HCFCs. Izingxoxo zamanje nge-Montreal Protocol zingase zilungiswe ukuze kube lula ukususwa kwama-hydrofluorocarbons noma ama-HFCs.

 

I-GWP

I-Global Warming Potential, noma i-GWP, iyisilinganiso sokuthi ukungcola kwesimo sezulu kubhubhisa kangakanani. I-GWP yegesi ibhekisela kumnikelo ophelele ekufudumaleni komhlaba obangelwa ukukhishwa kweyunithi eyodwa yaleyo gesi uma kuqhathaniswa neyunithi eyodwa yegesi ebhekiselwe kuyo, i-CO2, enikezwe inani elingu-1. Ama-GWP angasetshenziswa futhi ukuchaza umthelela wamagesi okushisa umhlaba azoba nawo ekufudumaleni komhlaba ngezikhathi ezahlukene noma ngezikhathi ezahlukene. Lokhu kuvame ukuba yiminyaka engama-20, iminyaka eyi-100, kanye neminyaka engama-500. Isikhathi seminyaka eyi-100 sisetshenziswa abalawuli. Lapha sisebenzisa isikhathi seminyaka eyi-100 eshadini elilandelayo.

 

I-ODP

I-Ozone Depletion Potential, noma i-ODP, iyisilinganiso sokuthi ikhemikhali ingadala umonakalo ongakanani ongqimbeni lwe-ozone uma kuqhathaniswa nesisindo esifanayo se-trichlorofluoromethane (CFC-11). I-CFC-11, enekhono lokunciphisa i-ozone elingu-1.0, isetshenziswa njengesibalo esiyisisekelo sokulinganisa ikhono lokunciphisa i-ozone.

 

Isikhathi Sokuphila Esisemkhathini

Isikhathi sokuphila kwezinhlobo zezilwane silinganisa isikhathi esidingekayo ukuze kubuyiselwe ukulingana emkhathini ngemva kokwanda noma ukwehla ngokuzumayo kokuhlushwa kwezinhlobo ezikhulunywa ngazo emkhathini.

 

Nasi ishadi elibonisa i-GWP, i-ODP kanye ne-Atmospheric Lifetime yamafriji ahlukene.
