Iziqandisi

I-HVAC, Iziqandisi kanye nama-air conditioner asetshenziswa kakhulu emadolobheni amaningi, ezindlini nasezimotweni.Iziqandisi nama-air conditioner zenza ingxenye enkulu yokuthengiswa kwempahla yasendlini.Inani lamafriji nama-air conditioner emhlabeni liyinombolo enkulu.Isizathu sokuthi kungani amafriji nama-air conditioner angaphola kungenxa yengxenye yokhiye oyinhloko, i-compressor.I-compressor isebenzisa isiqandisi ukuthutha amandla okushisa ngesikhathi sokusebenza.Iziqandisi zinezinhlobo eziningi.Ezinye iziqandisi ezivamile ezisetshenziswe kusukela kudala zilimaza ungqimba lwe-ozone futhi zibe nomthelela wokufudumala kwembulunga yonke.Ngakho-ke, ohulumeni nezinhlangano balawula ukusetshenziswa kweziqandisi ezahlukene.

 

I-Montreal Protocol

I-Montreal Protocol yisivumelwano somhlaba wonke sokuvikela ungqimba lwe-ozone yomhlaba ngokuqeda amakhemikhali aluqedayo.Ngo-2007, Isinqumo esidumile XIX/6, esathathwa ngo-2007, ukulungisa iProtocol ukuze kusheshiswe isigaba sokuphuma kuma-Hydrochlorofluorocarbons noma ama-HCFC.Izingxoxo zamanje nge-Montreal Protocol ezingase zichitshiyelwe ukuze kube lula ukwehliswa kwe-hydrofluorocarbons noma ama-HFC.

 

GWP

I-Global Warming Potential, noma i-GWP, isilinganiso sokuthi ukungcola kwesimo sezulu kuyingozi kangakanani.I-GWP yegesi isho inani eliphelele lokufaka ukufudumala kwembulunga yonke okuvela ekukhishweni kweyunithi eyodwa yaleyo gesi uma kuqhathaniswa neyunithi eyodwa yegesi eyinkomba, i-CO2, enikezwe inani elingu-1. Ama-GWP angasetshenziswa futhi ukuchaza amagesi abamba ukushisa azoba nawo ekufudumaleni komhlaba ngezikhathi ezihlukene noma emikhawulweni yesikhathi.Ngokuvamile lena iminyaka engu-20, iminyaka eyikhulu, neminyaka engu-500.Isikhathi esiyiminyaka eyi-100 sisetshenziswa abalawuli.Lapha sisebenzisa umkhathizwe wesikhathi weminyaka eyi-100 eshadini elilandelayo.

 

I-ODP

I-Ozone Depletion Potential, noma i-ODP, isilinganiso sokuthi ungakanani umonakalo ongadalwa yikhemikhali kungqimba lwe-ozone uma kuqhathaniswa nesisindo esifanayo se-trichlorofluoromethane (CFC-11).I-CFC-11, enamandla okuqeda i-ozone engu-1.0, isetshenziswa njengenani eliyisisekelo lokulinganisa amandla okuqeda i-ozone.

 

I-Atmospheric Lifetime

Isikhathi sokuphila somkhathi sohlobo oluthile sikala isikhathi esidingekayo ukuze kubuyiselwe ukulingana emkhathini kulandela ukwanda noma ukuncipha okungazelelwe kokuhlushwa kwezinhlobo zezilwane okukhulunywa ngazo emkhathini.

 

Nali ishadi elibonisa iziqandisi ezihlukene ze-GWP, i-ODP kanye ne-Atmospheric Lifetime.
