GWP, ODP a me Atmospheric Lifetime o nā mea hoʻoheheʻe

GWP, ODP a me ka Atmospheric Lifetime of Refrigerants

ʻO nā pahu hau

Hoʻohana maʻamau ʻia ka HVAC, nā pahu hau a me nā ea ma nā kūlanakauhale he nui, nā hale a me nā kaʻa.ʻO nā pahu hau a me nā ea ea no ka hapa nui o nā mea kūʻai hale.He helu nui ka helu o nā pahu hau a me nā ea ma ka honua.ʻO ke kumu e hiki ai i nā pahu hau a me nā ea ea ke hoʻolili ma muli o ke kumu kī nui, ka compressor.Hoʻohana ka compressor i ka refrigerant e lawe i ka ikehu wela i ka wā o ka hana.He nui nā ʻano o ka refrigerants.ʻO kekahi mau mea hoʻoheheʻe maʻamau i hoʻohana ʻia mai ka wā lōʻihi e hōʻino ana i ka papa ozone a hoʻopilikia i ka hoʻomehana honua.No laila, ke hoʻoponopono nei nā aupuni a me nā hui i ka hoʻohana ʻana i nā refrigerants like ʻole.

 

Kuʻikahi o Montreal

ʻO Montreal Protocol kahi ʻaelike honua no ka pale ʻana i ka papa ozone o ka Honua ma ka hoʻopau ʻana i nā kemika e hoʻopau ai.Ma 2007, ʻO ka Hoʻoholo kaulana XIX/6, i lawe ʻia i ka makahiki 2007, e hoʻoponopono i ka Protocol e hoʻolalelale i ka pae mai Hydrochlorofluorocarbons a i ʻole HCFC.Hiki ke hoʻololi ʻia nā kūkākūkā o kēia manawa e pili ana i ka Montreal Protocol e hoʻomaʻamaʻa i ka hoʻohaʻahaʻa ʻana o nā hydrofluorocarbons a i ʻole HFC.

 ODP, Ozone Depletion Potential mai ka protocol montreal

GWP

ʻO ka Global Warming Potential, a i ʻole GWP, he ana ia o ka hoʻopōʻino ʻana o ka mea haumia aniau.ʻO ka GWP o ke kinoea e pili ana i ka nui o ka hāʻawi ʻana i ka hoʻomehana honua ma muli o ka hoʻokuʻu ʻia ʻana o hoʻokahi ʻāpana o ia kinoea e pili ana i hoʻokahi ʻāpana o ke kinoea kuhikuhi, CO2, i hāʻawi ʻia i ka waiwai o 1. Hiki ke hoʻohana ʻia nā GWPs e wehewehe i ka ka hopena o nā kinoea ʻōmaʻomaʻo i ka hoʻomehana honua i nā manawa like ʻole a i ʻole nā ​​ʻaoʻao o ka manawa.He 20 makahiki, 100 makahiki, a me 500 makahiki.Hoʻohana ʻia kahi manawa o 100 mau makahiki e nā regulators.Maanei mākou e hoʻohana ai i ka manawa o 100 makahiki ma ka pakuhi aʻe.

 

ODP

ʻO ka Ozone Depletion Potential, a i ʻole ODP, he ana ia o ka nui o ka pōʻino e hiki ke hana ʻia e kekahi kemika i ka papa ozone i hoʻohālikelike ʻia me ka nui like o trichlorofluoromethane (CFC-11).Hoʻohana ʻia ʻo CFC-11, me ka hiki ke hoʻopau ozone o 1.0, ma ke ʻano he kumu kumu no ke ana ʻana i ka hiki ke hoʻemi ʻia ka ozone.

 

Ka Lewa Ola

ʻO ke ola o ka lewa o kekahi ʻano mea e ana i ka manawa i koi ʻia e hoʻihoʻi i ke kaulike i ka lewa ma hope o ka piʻi koke ʻana a i ʻole ka emi ʻana o ka ʻike o ka ʻano i nīnau ʻia i ka lewa.

 

Eia ka pakuhi e hōʻike i nā mea hoʻoheheʻe ʻokoʻa 'GWP, ODP a me Atmospheric Lifetime.

Heluhelu i nā leka ʻē aʻe

He aha ka Defrost System i loko o ka pahu hau kalepa?

He nui ka poʻe i lohe i ka huaʻōlelo "defrost" i ka wā e hoʻohana ai i ka pahu hau pāʻoihana.Inā ua hoʻohana ʻoe i kāu pahu hau a i ʻole ka pahu hau no kekahi manawa, i ka manawa ...

He mea koʻikoʻi ka mālama ʻana i nā meaʻai kūpono i mea e pale ai i ka hoʻohaumia kea...

ʻO ka mālama pono ʻole ʻana i ka meaʻai i loko o ka friji hiki ke alakaʻi i ka cross-contamination, ka mea e hopena i nā pilikia olakino koʻikoʻi e like me ka make ʻana o ka meaʻai a me ka meaʻai ...

Pehea e pale aku ai i kāu mau pahu hau ʻoihana mai ka nui loa ...

ʻO nā pahu hau ʻoihana nā mea pono a me nā mea hana o nā hale kūʻai kūʻai a me nā hale ʻaina, no nā ʻano huahana like ʻole i mālama ʻia i kūʻai pinepine ʻia ...

ʻO kā mākou huahana
