Mafiriji

Ma HVAC, mafiriji ndi ma air conditioner amagwiritsidwa ntchito kwambiri m'mizinda yambiri, m'nyumba ndi m'magalimoto. Mafiriji ndi ma air conditioner ndi omwe amachititsa kuti zipangizo zapakhomo zizigulitsidwa kwambiri. Chiwerengero cha mafiriji ndi ma air conditioner padziko lonse lapansi ndi chachikulu kwambiri. Chifukwa chomwe mafiriji ndi ma air conditioner amatha kuziziritsa ndi chifukwa cha gawo lalikulu la compressor. Compressor imagwiritsa ntchito refrigerant kunyamula mphamvu yotentha panthawi yogwira ntchito. Ma refrigerant ali ndi mitundu yambiri. Ma refrigerant ena omwe amagwiritsidwa ntchito nthawi zambiri amawononga ozone layer ndipo amakhudza kutentha kwa dziko. Chifukwa chake, maboma ndi mabungwe akulamulira kagwiritsidwe ntchito ka ma refrigerant osiyanasiyana.

 

Chigwirizano cha Montreal

Montreal Protocol ndi mgwirizano wapadziko lonse lapansi woteteza ozone layer ya Dziko Lapansi pochotsa mankhwala omwe amaliwononga. Mu 2007, The Famous Decision XIX/6, yomwe idachitika mu 2007, idasintha Protocol kuti ifulumizitse gawo lochotsa Hydrochlorofluorocarbons kapena HCFCs. Zokambirana zomwe zikuchitika pa Montreal Protocol zitha kusinthidwa kuti zithandize kuchepetsa ma hydrofluorocarbons kapena HFCs.

 

GWP

Mphamvu Yotentha Padziko Lonse, kapena GWP, ndi muyeso wa momwe choipitsa nyengo chimawonongera. GWP ya mpweya imatanthauza gawo lonse la kutentha kwa dziko lapansi chifukwa cha kutulutsa kwa unit imodzi ya mpweya umenewo poyerekeza ndi unit imodzi ya mpweya wotchulidwa, CO2, womwe umapatsidwa mtengo wa 1. GWPs ingagwiritsidwenso ntchito kufotokoza momwe mpweya wotentha udzakhudzire kutentha kwa dziko lapansi pa nthawi zosiyanasiyana kapena nthawi zosiyanasiyana. Izi nthawi zambiri zimakhala zaka 20, zaka 100, ndi zaka 500. Nthawi ya zaka 100 imagwiritsidwa ntchito ndi olamulira. Pano tikugwiritsa ntchito nthawi ya zaka 100 mu tchati chotsatirachi.

 

ODP

Kutha kwa Ozone, kapena ODP, ndi muyeso wa kuchuluka kwa kuwonongeka komwe mankhwala angayambitse ku ozone layer poyerekeza ndi kuchuluka kofanana kwa trichlorofluoromethane (CFC-11). CFC-11, yokhala ndi mphamvu yotha kwa ozone ya 1.0, imagwiritsidwa ntchito ngati chiŵerengero choyambira poyesa mphamvu yotha kwa ozone.

 

Moyo Wathunthu Wamlengalenga

Nthawi ya moyo wa zamoyo mumlengalenga imayesa nthawi yomwe imafunika kuti zibwezeretse mgwirizano mumlengalenga pambuyo pa kuwonjezeka kapena kuchepa kwadzidzidzi kwa kuchuluka kwa zamoyo zomwe zikukambidwa mumlengalenga.

 

Nayi tchati chosonyeza mitundu yosiyanasiyana ya ma refrigerants monga GWP, ODP ndi Atmospheric Lifetime.
