Mafiriji
HVAC, mafiriji nemaair conditioner zvinowanzo shandiswa mumaguta akawanda, mudzimba nemota. Mafiriji nemaair conditioner ndiwo anonyanya kutengeswa mumidziyo yepamba. Huwandu hwemafiriji nemaair conditioner pasi rose hwakawanda. Chikonzero chinoita kuti mafiriji nemaair conditioner atonhore imhaka yechinhu chikuru, compressor. Compressor inoshandisa refrigerant kutakura simba rekupisa panguva yekushanda. Mafiriji ane mhando dzakasiyana-siyana. Mamwe mafiriji akajairwa anoshandiswa kubva kare anokuvadza ozone layer uye anokanganisa kupisa kwenyika. Saka, hurumende nemasangano vari kutonga mashandisirwo emafiriji akasiyana.
Chibvumirano cheMontreal
Chibvumirano cheMontreal chibvumirano chepasi rose chekudzivirira ozone layer yepasi nekudzima makemikari anoipedza. Muna 2007, Chisarudzo chakakurumbira XIX/6, chakaitwa muna 2007, chekugadzirisa Chibvumirano kuti kukurumidzise chikamu chekubuda kweHydrochlorofluorocarbons kana HCFCs. Hurukuro dziripo paMontreal Protocol dzingangogadziriswa kuti dzibatsire kudzikiswa kwehydrofluorocarbons kana HFCs.
GWP
Kugona Kupisa Kwepasi Pose, kana kuti GWP, chiyero chekuti chinhu chinosvibisa mamiriro ekunze chinoparadza sei. GWP yegesi inoreva mupiro wese wekudziya kwepasi rose unobva mukuburitswa kweyuniti imwe chete yegesi iyoyo zvichienzaniswa neyuniti imwe yegasi rekare, CO2, iro rinopiwa kukosha kwe1. GWP dzinogonawo kushandiswa kutsanangura kukanganiswa kuchaita magasi ekupisa pasi rose pakudziya kwepasi rose munguva dzakasiyana kana nguva. Izvi zvinowanzova makore makumi maviri, makore zana, uye makore mazana mashanu. Nguva inosvika makore zana inoshandiswa nevanodzora. Pano tinoshandisa nguva inosvika makore zana muchati inotevera.
ODP
Kupera kweOzone, kana kuti ODP, chiyero chekuti kemikari inogona kukonzera kukuvara kwakadini ku ozone layer kana tichienzanisa nehuremu hwakafanana hwe trichlorofluoromethane (CFC-11). CFC-11, ine simba rekubvisa ozone re1.0, inoshandiswa sehwaro hwekuyera simba rekubvisa ozone.
Hupenyu hwese hwemumhepo
Nguva yehupenyu hwemhuka mumhepo inoyera nguva inodiwa kuti pave nekuenzana mumhepo mushure mekuwedzera kana kudzikira kwehuwandu hwemhuka dziri kutaurwa nezvadzo mumhepo.
Heino chati inoratidza mafiriji akasiyana-siyana eGWP, ODP uye Atmospheric Lifetime.
