He aha nā hydrocarbons (HCs)

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

ʻO kēia mau mea a pau e hiki ke hoʻopau ʻia a ʻaʻohe mea ʻawaʻawa e like me ka ASHRAE 34 palekana: ʻo kā lākou papa palekana ʻo A3, me ka "A" ʻo ia ka "haʻahaʻa haʻahaʻa" a me ka "3" ʻo ia hoʻi "ke ahi kiʻekiʻe".

 

 

Nā pōmaikaʻi o nā HC ma ke ʻano he refrigerants

ʻEkolu mau pōmaikaʻi nui:

Hiki ke hoʻomehana honua haʻahaʻa

He haʻahaʻa loa ka hiki ʻana o ka hoʻomehana honua i nā HC, No laila kōkua ia i ka hōʻemi ʻana i ka CO₂hoʻokuʻu inā hoʻohana mākou i nā hydrocarbons e like me ka refrigerant.

Hoʻomaka maikaʻi ʻia mai ke ʻano

Wehe ʻia nā HC mai ka lepo, me ka ʻaila pū kekahi. ʻO kā lākou mālama ma ka Honua he nui loa. A ʻoi aku ka maʻalahi o ka paʻi ʻana iā lākou, ʻoi aku ka haʻahaʻa o kā lākou kumukūʻai ma mua o nā refrigerants synthetic ʻē aʻe.

ʻOi aku ka maikaʻi o ka hana refrigerant

 ʻOi aku ka maikaʻi o ka hana ʻana o nā HC i ka hoʻoluʻu a me ka hoʻomehana ʻana ma ke ʻano he refrigerant ma mua o nā mea ʻē aʻe. ʻO ka ʻoiaʻiʻo, ʻoi aku ka nui o kā lākou wela huna o ka vaporization ma mua o nā mea hoʻoheheʻe synthetic ʻē aʻe, ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o ka hopena hoʻomaha a me ka hoʻoheheʻe ʻana i ka nui like.

 Ka hoʻomaikaʻi ʻana i ka ikehu

Hōʻike nā haʻawina hiʻohiʻona i ka neʻe ʻana mai ka HFC R404A i ka R290 refrigerant maoli, ma ka awelika, hiki ke ʻae i ka hoʻomaikaʻi ʻana i ka 10 pākēneka o ka mālama ʻana i ka ikehu.

ʻOi aku ka maikaʻi o ka wela wela ma ke ʻano o ka compressor

E like me nā mea hoʻoheheʻe kūlohelohe, aia nā huila synthetic hou i loaʻa i ka mākeke me ka GWP haʻahaʻa, ʻike ʻia ʻo A2Ls. Hōʻike ka papaʻaina (kiʻi) i nā kumu nui e pono e noʻonoʻo i ka wā e hoʻoholo ai. ʻO kekahi o kēia mau pae hoʻohālikelike ʻo ke ʻano wela, ʻoi aku ka maikaʻi o nā mea hoʻoheheʻe kūlohelohe, ʻo ia hoʻi, ʻaʻole ia e wela i ka compressor e like me nā A2L. Hāʻawi kēia hiʻohiʻona i ka pono o ka ikehu a me ka hilinaʻi o ka compressor.
