ʻO ka wet rent factor µ kahi palena e hōʻike ana i ka hiki o ka mea ke kūʻē i ke komo ʻana o ka mahu wai a he nui ʻole ia. ʻO ke anakahi ʻo m, ʻo ia hoʻi, ua like ia me ka permeability mahu wai o ka ea o m. Hōʻike ia i ka hana o ka mea, ʻaʻole ka hana o ka huahana a i ʻole ke ʻano.
No nā mea insulation me ka conductivity thermal mua like ʻo K akā ʻokoʻa ka µ, ʻo ke kiʻekiʻe o ka waiwai µ, ʻoi aku ka paʻakikī o ke komo ʻana o ka mahu wai i loko o ka mea, no laila e piʻi mālie ana ka conductivity thermal, a ʻoi aku ka lōʻihi o ka manawa e hiki ai i ka hāʻule ʻana o ka insulation, a ʻoi aku ka lōʻihi o ke ola lawelawe.
Ke haʻahaʻa ka waiwai µ, hiki ka conductivity thermal i ka waiwai hāʻule i ka manawa pōkole ma muli o ke komo wikiwiki ʻana o ka mahu wai. No laila, ʻo ka mānoanoa hoʻolālā mānoanoa wale nō ke hiki ke hoʻokō i ke ola lawelawe like me nā mea waiwai µ kiʻekiʻe.
Hoʻohana nā huahana Jinfulai i nā kumu hoʻolimalima pulu kiʻekiʻe e hōʻoia i ka conductivity thermal paʻa, no laila hiki i ka mānoanoa mua lahilahi ke hōʻoia i ke ola lawelawe.
He aha ka pilina ma waena o ka conductivity thermal a me ka wet rent factor o ka mea insulation?
