- Ka hoʻokaʻawale ʻana o ka mahana mālama anu:
Hoʻokaʻawale pinepine ʻia ka mālama anuanu i ʻehā mau ʻano: ka wela kiʻekiʻe, ka wela haʻahaʻa a me ka mahana haʻahaʻa, ka wela haʻahaʻa a me ka wela ultra-low.
Pono nā huahana likeʻole i nā mahana likeʻole.
A. Kiʻekiʻe wela wela wela
ʻO ka mālama anu anuanu kiʻekiʻe ka mea a mākou i kapa ai i ka mālama anu anuanu. Hoʻopili i ka mahana ma kahi o 0 ° C, a ʻo ka hoʻoluʻu ʻana i ka ea me kahi mea hoʻomaha.
B. Medium a me ka haʻahaʻa wela ka mālama anu
ʻO ka mālama anu anuanu a me ka haʻahaʻa haʻahaʻa ʻo ia ke kiʻekiʻe kiʻekiʻe o ka mālama ʻana i ke anu anuanu, ʻo ka mahana maʻamau i loko o -18 ° C, a hoʻohana nui ʻia e mālama i ka ʻiʻo, nā wai wai a me nā mea kūʻai kūpono no kēia pae wela.
C, mālama anu anuanu haʻahaʻa haʻahaʻa
ʻO ka mālama anuanu haʻahaʻa haʻahaʻa, ʻike ʻia hoʻi ʻo ka mālama ʻana i ka hau, ka mālama ʻana i ke anuanu, ʻo ka maʻamau ka mahana o ka mālama ʻana ma kahi o -20 ° C ~ -30 ° C, a hoʻopau ʻia ka hoʻoheheʻe ʻana o ka meaʻai e ka ea a i ʻole nā mea hoʻoheheʻe kūikawā.
D. Ultra-haʻahaʻa wela anuanu waihona
Hoʻohana nui ʻia ka mālama ʻana i ke anuanu ultra-haʻahaʻa, ≤-30 °C no ka meaʻai wikiwiki a me nā kumu kūikawā e like me nā hoʻokolohua ʻoihana a me nā lāʻau lapaʻau. Ke hoʻohālikelike ʻia me nā mea ʻekolu i luna, pono e liʻiliʻi iki nā noi ma ka mākeke.
2. Ka helu ʻana i ka hiki ke mālama i ka mālama anu
E helu i ke tonana o ka waihona anu: (helu ʻia e like me nā kikoʻī hoʻolālā o ka waihona anu a me nā kūlana ʻāina kūpono no ka hiki ke mālama i ka waihona anu):
ʻO ka nui o loko o ka lumi i hoʻopaʻa ʻia × ka helu hoʻohana nui × ka paona o ka meaʻai = ke tonane 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: ʻo ka wahi i loko o ka waihona anu - ka wahi e pono ai e hoʻokaʻawale ʻia i loko o ka hale kūʻai, ke kūlana i noho ʻia e nā lako o loko, a me kahi e pono ai e mālama ʻia no ka holo ʻana o ka ea i loko;
ʻO ka lua o ka ʻanuʻu, ʻo ia ka ʻimi ʻana i ke kaumaha o nā mea i hiki ke mālama ʻia i kēlā me kēia mika cubic o ke ākea e like me ke ʻano o nā mea waiwai, a e hoʻonui i kēia e loaʻa ai ka nui o nā huahana 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: E like me kā mākou ʻike, ʻoi aku ka nui o ka leo hoʻohana maoli ma mua o ka coefficient hoʻohana nui i wehewehe ʻia e ke kūlana aupuni. No ka laʻana, he 0.4 ka maʻamau maʻamau 1000 cubic mika o ka hoʻohana ʻana i nā mea hoʻohana anuanu. Inā hoʻokomo ʻia i ka ʻepekema a me ka maikaʻi, hiki i ka coefficient hoʻohana maoli ke hiki i ka 0.5. -0.6.
ʻO ke kaumaha o ka meaʻai i loko o ka waihona anu.
ʻO ka ʻiʻo maloʻo: 0.40 tons hiki ke mālama ʻia i ka mika cubic;
Nā iʻa paʻa hau: 0.47 tona no ka mika cubic;
ʻO nā huaʻai hou a me nā huaʻai: hiki ke mālama ʻia 0.23 tons i kēlā me kēia mika cubic;
ʻO ka hau i hana ʻia e ka mīkini: 0.75 tons no ka mika cubic;
Ka lua hipa maloʻo: 0.25 tons hiki ke mālama ʻia i ka mika cubic;
ʻO ka ʻiʻo deboned: 0.60 tons no ka mika cubic;
