He aha nā hydrocarbons (HCs)

ʻO nā Hydrocarbons (HCs) he mau mea i haku ʻia me nā ʻātoma hydrogen i hoʻopaʻa ʻia i nā ʻātoma kalapona. ʻO nā laʻana, ʻo ia ka methane (CH4), propane (C3H8), propene (C3H6, i ʻike ʻia hoʻi ʻo propylene) a me ka butane (C4H10).

He mau mea lapalapa kēia a ʻaʻohe mea ʻawahia e like me ka hoʻokaʻawale palekana ASHRAE 34: ʻo ko lākou papa palekana ʻo A3, me ka "A" ʻo ia hoʻi "haʻahaʻa ka ʻawahia" a ʻo ka "3" ʻo ia hoʻi "kiʻekiʻe ka lapalapa ʻana".

 

 

Nā Pōmaikaʻi o nā HC e like me nā refrigerants

ʻEkolu mau pono nui:

Ka emi ʻana o ka hiki ke hoʻomehana honua

He haʻahaʻa loa ka hiki o nā HC ke hoʻomehana honua, no laila kōkua ia i ka hōʻemi ʻana i ka CO2₂nā hoʻokuʻu ʻana inā hoʻohana mākou i nā hydrocarbons ma ke ʻano he refrigerant.

Mai ke kūlohelohe mai ka ʻano maoli

Hoʻokaʻawale ʻia nā HC mai ka lepo, me ka ʻaila pū kekahi. He nui loa ko lākou mau waihona ma ka Honua. A he mea maʻalahi hoʻi ke hoʻohana ʻana iā lākou, ʻoi aku ka haʻahaʻa o ko lākou kumukūʻai ma mua o nā refrigerants synthetic ʻē aʻe.

Hana maikaʻi o ka refrigerant

 Hana maikaʻi nā HC i ka hoʻomaʻalili/hoʻomehana ʻana ma ke ʻano he refrigerant ma mua o nā mea ʻē aʻe. ʻO ka ʻoiaʻiʻo, ʻoi aku ka pālua o ko lākou wela latent o ka vaporization ma mua o nā refrigerants synthetic ʻē aʻe, ʻo ia hoʻi ka hopena hoʻomaʻalili/hoʻomehana kiʻekiʻe me ke kahe like o ka nui o ka refrigerant.

 Ka hoʻomaikaʻi ʻana i ka pono o ka ikehu

Ua hōʻike ʻia nā haʻawina hihia hiki i ka neʻe ʻana mai ka HFC R404A i ka refrigerant kūlohelohe R290, ma ka awelika, ke ʻae i ka hoʻomaikaʻi ʻana i ka mālama ʻana i ka ikehu a hiki i ka 10 pakeneka.

ʻOi aku ka maikaʻi o ka ʻōnaehana wela ma ka makemake o ka compressor

Ma ke ʻano like me nā refrigerants kūlohelohe, aia nā hui synthetic hou i loaʻa ma ka mākeke me ka GWP haʻahaʻa, i ʻike ʻia hoʻi ʻo A2Ls. Hōʻike ka papa (kiʻi) i nā pae nui e pono e noʻonoʻo ʻia i ka wā e hoʻoholo ai. ʻO kekahi o kēia mau pae, ʻo ia ke ʻano thermal, ʻoi aku ka maikaʻi ma nā refrigerants kūlohelohe, ʻo ia hoʻi, ʻaʻole ia e hoʻomehana i ka compressor e like me nā A2Ls. Hāʻawi kēia ʻano i ka pono o ka ikehu a me ka hilinaʻi o ka compressor.
