-25 ℃ Ka mālama anu haʻahaʻa haʻahaʻa

Nā kiʻi o ka lumi mālama mahana haʻahaʻa ʻO ka mahana mālama o ka lumi mālama mahana haʻahaʻa maʻamau: -22～-25℃. 

No ka mea, pono e mālama ʻia kekahi mau meaʻai e like me ka ice cream a me nā meaʻai kai a me nā huahana ʻiʻo ʻē aʻe ma ka mahana o -25°C ma mua o ko lākou pala ʻana, inā e mālama ʻia ka ice cream ma lalo o 25°C, e nalowale kona ʻala; ʻOi aku ka ʻino o ka ʻono a me ka ʻono; ʻo ke ʻano o ka mālama ʻana i ka mahana haʻahaʻa: hoʻokomo mālie ʻia ka meaʻai i loko o ka mālama anu i kēlā me kēia manawa. Ma hope o kekahi manawa, hiki ka mahana o ka mālama anu i -25℃. ʻAʻohe koi kūikawā no kēia wā. He mau koi koʻikoʻi ko ka mahana mālama, ma waena o -22℃～25℃, he mālama mahana haʻahaʻa maʻamau kēia.

Ke ʻano helu ʻana i ka hiki ke mālama anu

● Ka helu ʻana o nā tona waihona anu:

1. Tonnage mālama anu = ka nui o loko o ka lumi mālama anu × kumu hoʻohana nui × kaumaha o ka meaʻai.

2. ʻO ka nui o loko o ka lumi mālama anu o ka waihona anu = ka lōʻihi o loko × ka laulā × ke kiʻekiʻe (cubic)

3. Ka nui o ka hoʻohana ʻana i ka nui o ka mālama anu:

500～1000 mika kūpika = 0.40

1001～2000 cubic = 0.50

2001～10000 mika kūpika = 0.55

10001～15000 mika kūpika = 0.60

● Kaumaha o ka ʻāpana meaʻai:

ʻAiʻo paʻahau = 0.40 tons/cubic

Iʻa paʻahau = 0.47 tons/cubic

Nā huaʻai a me nā mea kanu hou = 0.23 tons/m3

Hau i hana ʻia e ka mīkini = 0.75 tons/cubic

Lua hipa paʻahau = 0.25 tons/cubic

ʻAi ʻiʻo a i ʻole nā ​​huahana ʻaoʻao ʻole = 0.60 tons/cubic

Manu i hoʻopaʻahau ʻia i loko o nā pahu = 0.55 tons/m3

● Ke ʻano helu o ka nui o ka waihona mālama anu:

1. Ma ka ʻoihana waihona, ʻo ke ʻano hana no ka helu ʻana i ka nui o ka waihona:

Ka nui o ka ʻike kūpono (m3) = ka nui o ka ʻike holoʻokoʻa (m3) X0.9

Ka nui o ka mālama ʻana (tona) = ka nui o loko (m3)/2.5m3

2. Ka nui maoli o ka mālama ʻana o ka waihona anu kelepona

Ka nui o ka ʻike kūpono (m3) = ka nui o ka ʻike holoʻokoʻa (m3) X0.9

Ka nui o ka mālama ʻana (tona) = ka nui o loko (m3) X (0.4-0.6)/2.5m3

Hoʻoholo ʻia ʻo 0.4-0.6 e ka nui a me ka mālama ʻana o ka waihona anu.

3. Ka nui o ka mālama ʻana i kēlā me kēia lā i hoʻohana ʻia

Inā ʻaʻohe hoʻolālā kūikawā, ua helu ʻia ka nui o ka waihona i kēlā me kēia lā ma 15% a i ʻole 30% o ka nui o ka waihona (tona) (ma ke ʻano maʻamau ua helu ʻia he 30% no ka poʻe ma lalo o 100m3).
