He aha ngā hauwaiwaro (HC)

Ko ngā hauwaiwaro (HC) he matū i hangaia mai i ngā ngota hauwai e herea ana ki ngā ngota waro. Hei tauira, ko te methane (CH4), te propane (C3H8), te propene (C3H6, e mōhiotia ana ko te propylene) me te butane (C4H10).

He mura katoa ēnei, ā, kāore he paitini e ai ki te whakarōpūtanga haumaru ASHRAE 34: ko tō rātou akomanga haumaru ko A3, ko te tikanga o te "A" he "paitini iti" me te tikanga o te "3" he "mura nui".

 

 

Ngā painga o ngā HC hei whakamatao

E toru ngā painga matua:

Te iti o te kaha ki te whakamahana o te ao

He iti rawa te kaha o ngā HC ki te whakamahana i te ao, nō reira ka āwhina i te whakaiti i te CO2₂ngā tukunga mēnā ka whakamahia e tātou ngā hauwaiwaro hei whakamatao.

I ahu mai i te taiao i te huarahi ngāwari

Ka tangohia ngā HC mai i te oneone, me te hinu anō hoki. He nui rawa ō rātou rahui i runga i te Ao. Ā, he watea hoki te whakamahi i aua mea, he iti iho hoki te utu i ērā atu hauhautanga hangai.

He pai ake te mahi a te pouaka whakamātao

 He pai ake te mahi a ngā HC ki te whakamatao/whakamahana hei hauhautanga i ērā atu. Inaa, e rua te teitei ake o te wera huna o te mimiti i ērā atu hauhautanga hangai, ko te tikanga he nui ake te pānga whakamatao/whakamahana me te rere papatipu hauhautanga ōrite.

 Te whakapai ake i te whai huatanga o te pūngao

E whakaatu ana ngā rangahau take mā te nekehanga mai i te HFC R404A ki te hau mātao taiao R290, i te toharite, ka taea te whakapai ake i te penapena pūngao tae atu ki te 10 ōrau.

He pai ake te pūnaha wera hei painga mō te compressor

I tua atu i ngā hauhautanga taiao, kei reira anō ngā ranunga hanga hou e wātea ana i te mākete me te GWP iti, e mōhiotia ana ko ngā A2L. E whakaatu ana te ripanga (kei te pikitia) i ngā paearu matua me whai whakaaro ina whakatau ana. Ko tētahi o ēnei paearu ko te pūnaha wera, he pai ake i roto i ngā hauhautanga taiao, arā, kāore e wera nui te pūhiko pērā i ngā A2L. Ka whai wāhi tēnei āhuatanga ki te whai huatanga o te pūngao me te pono o te pūhiko.
