GWP, ODP uye Atmospheric Hupenyu hweMafiriji
Refrigerants
HVAC, Refrigerators uye air conditioners anowanzoshandiswa mumaguta akawanda, dzimba nemotokari.Mafiriji uye ma air conditioners anoverengera chikamu chikuru chekutengesa midziyo yemumba.Huwandu hwemafiriji nemaair conditioner munyika inhamba huru.Chikonzero nei mafiriji uye maair conditioner achigona kutonhorera imhaka yepakati kiyi chikamu, iyo compressor.Iyo compressor inoshandisa refrigerant kutakura kupisa simba panguva yekushanda.Mafiriji ane marudzi akawanda.Mamwe mafiriji akajairwa anoshandiswa kubvira kare ari kukuvadza ozone layer ine hushamwari uye inokanganisa kudziya kwepasirese.Saka, hurumende nemasangano vari kudzora kushandiswa kwemafiriji akasiyana.
Montreal Protocol
Montreal Protocol chibvumirano chepasi rose chekuchengetedza ozone layer yePasi nekubvisa makemikari anoipedza.Muna 2007, Iyo ine mukurumbira Decision XIX/6, yakatorwa muna 2007, kugadzirisa Protocol kuti ikurumidze kubuda muHydrochlorofluorocarbons kana HCFCs.Nhaurirano dzazvino pamusoro peMontreal Protocol dzingangogadziridzwa kuti dzifambise kudzika kwemahydrofluorocarbons kana HFCs.
GWP
Global Warming Potential, kana GWP, chiyero chekuparadza kusvibiswa kwemamiriro ekunze.GWP yegasi inoreva mupiro wakazara mukudziya kwepasi kunobva mukubuda kwechikamu chimwe chegasi iroro zvichienderana nechikamu chimwe chegasi rereferensi, CO2, iyo inopihwa kukosha kwe1. GWPs inogona kushandiswawo kutsanangura Kukanganisa kwemagasi egreenhouse kuchave nekudziya kwepasirese panguva dzakasiyana dzenguva kana nguva.Aya anowanzova makore makumi maviri, makore zana, uye makore mazana mashanu.Nguva yenguva yemakore zana inoshandiswa nevatongi.Pano tinoshandisa horizon yenguva yemakore zana muchati inotevera.
ODP
Ozone Depletion Potential, kana ODP, chiyero chekukuvadza kungaita kemikari kune ozone layer kana ichienzaniswa nehuremu hwakafanana hwe trichlorofluoromethane (CFC-11).CFC-11, ine ozone inopedza simba re 1.0, inoshandiswa sechiverengero chekutanga chekuyera ozone inopedza simba.
Atmospheric Lifetime
Hupenyu hwemuchadenga hwemhuka hunoyera nguva inodiwa kudzorera kuenzana mumhepo zvichitevera kuwedzera kana kuderera kwekusangana kwemarudzi ari kutaurwa mumhepo.
Heino chati kuratidza akasiyana mafiriji 'GWP, ODP uye Atmospheric Lifetime.
