He aha ka haʻahaʻa o ka mahu wela loa?

Hōʻike ka haʻahaʻa i ka nui kino o ka maloʻo o ka lewa. Ma kahi mahana a ma kekahi leo o ka ea, ʻo ka liʻiliʻi o ka mahu wai i loko, ʻoi aku ka maloʻo o ka ea; ʻoi aku ka nui o ka mahu wai, ʻoi aku ka haʻahaʻa o ka ea. ʻO ka degere o ka maloʻo a me ka haʻahaʻa o ka ea i kapa ʻia ʻo "humidity". Ma kēia manaʻo, hoʻohana mau ʻia nā nui kino e like me ka haʻahaʻa piha, ka haʻahaʻa pili, ka haʻahaʻa hoʻohālikelike, ka ratio hui ʻana, ka saturation a me ka wahi hau e hōʻike ai. Inā hōʻike ia i ke kaumaha o ka wai wai i loko o ka mahu mākū ma ke ʻano he pākēneka o ka nui o ke kaumaha o ka mahu, ua kapa ʻia ʻo ia ka humidity o ka mahu.

ʻO ka manaʻo o ka haʻahaʻa ka nui o ka mahu wai i loko o ka lewa. ʻEkolu ala e hōʻike ai:
1. Hōʻike ka haʻahaʻa haʻahaʻa i ka nui o ka mahu wai i loko o kēlā me kēia mika cubic o ka ea, ʻo ka ʻāpana he kg/m³;
2. ʻO ka moisture content, e hōʻike ana i ka nui o ka mahu wai i loko o ka kilokani o ka ea maloʻo, ʻo ka ʻāpana he kg / kg * ea maloʻo;
3. Hōʻike ka haʻahaʻa pili i ka ratio o ka haʻahaʻa haʻahaʻa ma ka lewa me ka haʻahaʻa piha piha i ka mahana like. He pākēneka ka helu, ʻo ia hoʻi, i loko o kekahi manawa, ua puʻunaue ʻia ka nui o ka mahu wai i loko o ka lewa ma kekahi wahi me ka nui o ka mahu wai ma ia mahana. pākēneka.

Ke hana nei ka mea hana mahu, ʻoi aku ka liʻiliʻi o ka haʻahaʻa pili, ʻoi aku ka nui o ka mamao ma waena o ka ea a me ka pae saturation, no laila ʻoi aku ka ikaika o ka hiki ʻana o ka wai. ʻO ia ke kumu e maloʻo maʻalahi ai nā lole pulu i nā lā lā i ka hoʻoilo. ʻO ka mahana wela a me ka mahana o ka ʻōpuʻu pulu E like me ka mea i ʻōlelo ʻia ma mua, ʻo ka mahu wai i loko o ka ea haʻahaʻa ʻole i hoʻopiha ʻia i kahi kūlana wela loa.

ʻO ke kaʻina hana paʻa mau o ka mahu superheated

Ua māhele ʻia ʻo ia i ʻekolu mau ʻanuʻu: ka hoʻomaʻamaʻa mua ʻana o ka wai unsaturated, ka vaporization mau o ka wai saturated, a me ka pumehana mau o ka mahu maloʻo maloʻo. ʻO ka wela i hoʻohui ʻia i ka pae hoʻomaʻamaʻa mau ʻana o ka wai unsaturated i kapa ʻia he wela wai; ʻo ka wela i hoʻohui ʻia i loko o ke kaʻina hoʻohuehu kaomi mau o ka wai kuʻuna i kapa ʻia ʻo ka wela vaporization; ʻo ka wela i hoʻohui ʻia i loko o ke kaʻina hoʻomohana mau o ka mahu maloʻo maloʻo ua kapa ʻia ʻo superheat.

(1) Māhu māhu: Ma lalo o kekahi kaomi, wela ka wai a paila, hoʻomaka ka wai māʻona e mahu, a lilo ka wai i mahu. I kēia manawa, ua like ka mahana o ka mahu me ka mahana saturation. Ua kapa ʻia ka mahu ma kēia mokuʻāina.
(2) Hoʻomau ʻia ka hoʻomehana ʻana o ka mahu ma muli o ka mahu kukū. ʻO ka mahana o ka mahu kuʻuna ma mua o kēia kaomi ʻana he mahu wela loa.
