- Ka hoʻokaʻawale ʻana o ka mahana mālama anu:
ʻO ka maʻamau, ua māhele ʻia ka mālama anu i ʻehā mau ʻano: ke kiʻekiʻe o ka mahana, ka waena a me ka haʻahaʻa o ka mahana, ka haʻahaʻa o ka mahana a me ka haʻahaʻa loa.
Pono nā huahana like ʻole i nā mahana like ʻole.
A. Ka mālama anu ʻana i ka mahana kiʻekiʻe
ʻO ka mālama anu wela kiʻekiʻe ka mea a mākou e kapa nei he mālama anu. Hoʻopili i ka mahana maʻamau ma kahi o 0°C, a hoʻoluʻu ea me kahi peʻahi hoʻoluʻu.
B. Ka mālama anu ʻana i ka mahana waena a me ka haʻahaʻa
ʻO ka mālama anu waena a me ka haʻahaʻa haʻahaʻa ka mālama anu kiʻekiʻe o ka mahana, ʻo ka mahana maʻamau i loko o -18°C, a hoʻohana nui ʻia e mālama i ka ʻiʻo, nā waiwai wai a me nā waiwai kūpono no kēia pae mahana.
C, mālama anu haʻahaʻa haʻahaʻa
ʻO ka mālama anu haʻahaʻa wela, i ʻike ʻia hoʻi ʻo ka mālama hau ʻana, ka mālama anu ʻana, ʻo ka mahana mālama maʻamau ma kahi o -20°C ~ -30°C, a hoʻopau ʻia ka hoʻopaʻa ʻana o ka meaʻai e ka ea hoʻoluʻu a i ʻole nā lako hoʻopaʻa kūikawā.
D. Ka mālama anu ʻana i ka mahana haʻahaʻa loa
ʻO ka mālama anu ʻana i ka mahana haʻahaʻa loa, ≤-30 °C mālama anu, hoʻohana nui ʻia no ka meaʻai hau wikiwiki a me nā kumu kūikawā e like me nā hoʻokolohua ʻoihana a me ka mālama ʻana i ke olakino. Ke hoʻohālikelike ʻia me nā mea ʻekolu i luna, pono e liʻiliʻi iki nā noi ma ka mākeke.
2. Ka helu ʻana o ka hiki ke mālama i ka mālama anu
E helu i ke kaumaha o ka waihona anu: (i helu ʻia e like me nā kikoʻī hoʻolālā o ka waihona anu a me nā kūlana aupuni pili no ka hiki ke mālama i ka waihona anu):
ʻO ka nui o loko o ka lumi hau × ka helu hoʻohana nui × ke kaumaha o ka meaʻai = ke tona o ka waihona anu.
ʻO ka hana mua, ʻo ia ka helu ʻana i ka wahi maoli i loaʻa a mālama ʻia i loko o ka waihona anu: ka wahi o loko o ka waihona anu - ka wahi alahele e pono e hoʻokaʻawale ʻia i loko o ka hale waihona, ke kūlana i noho ʻia e nā lako o loko, a me ka wahi e pono e mālama ʻia no ke kahe ʻana o ka ea o loko;
ʻO ka lua o ka hana, ʻo ia ke ʻike i ke kaumaha o nā mea hiki ke mālama ʻia no kēlā me kēia mika cubic o ka hakahaka e like me ke ʻano o nā mea waihona, a hoʻonui i kēia e loaʻa ai ka nui o nā tona o nā huahana e hiki ke mālama ʻia i loko o ka waihona anu;
500～1000 cubic = 0.40;
1001～2000 cubic = 0.50;
2001～10000 cubic = 0.55;
10001～15000 cubic = 0.60.
Nānā: Wahi a ko mākou ʻike, ʻoi aku ka nui o ka nui o ka mea hiki ke hoʻohana ʻia ma mua o ke koina hoʻohana nui i wehewehe ʻia e ke kūlana aupuni. No ka laʻana, ʻo ke koina hoʻohana mālama anu no 1000 mika cubic maʻamau o ke aupuni he 0.4. Inā kau ʻia ma ke ʻano ʻepekema a me ka maikaʻi, hiki i ke koina hoʻohana maoli ke hiki i ka 0.5. -0.6.
ʻO ke kaumaha o ka meaʻai ma ka waihona anu hana:
ʻAiʻo paʻahau: hiki ke mālama ʻia he 0.40 tone no kēlā me kēia mika cubic;
Iʻa paʻahau: 0.47 tons no ka mika cubic;
Nā huaʻai a me nā mea kanu hou: hiki ke mālama ʻia he 0.23 tone no kēlā me kēia mika cubic;
Hau i hana ʻia e ka mīkini: 0.75 tons no ka mika cubic;
Lua hipa paʻahau: hiki ke mālama ʻia he 0.25 tone no kēlā me kēia mika cubic;
ʻIʻo i wehe ʻia ka iwi: 0.60 tons no ka mika cubic;
