Ua manaʻo ʻia nā pākahi anti-solar e hana i ka uila i ka pō

No ka nui o kā mākou makemake e hoʻololi i nā kumu ikehu hiki ke hoʻololi ʻia, loaʻa iā lākou nā hemahema. ʻO nā panela lā, no ka laʻana, hana wale i nā hola o ke ao. I ka pō, hana ʻole lākou, a huki ʻia ka ikehu mai nā pākahi i hoʻopaʻa ʻia i ke ao. ʻO nā panela pāhawewe wela i hana ʻia e nā ʻepekema e kōkua i ka hoʻopuni ʻana i kēia palena.

E like me ka manaʻo o ka punaewele punaewele Hoʻopiʻi, Ua noi nā mea noiʻi mai ke Kulanui o Kaleponi Davis i ka manaʻo o nā paneli "anti-solar" hiki ke hoʻoulu i ka uila ma o ka hoʻokuʻu ʻana i ka wela i mālama ʻia mai nā paneli iā lākou iho (infrared radiation). Ma muli o ka emi ʻana o ka ikehu ma mua o ka pāhawewe ʻike ʻia, e hoʻopuka nā panela anti-solar a hiki i ka 25% o ka uila o nā panela lā maʻamau o ia wahi. Akā ʻoi aku ka maikaʻi o kēia ma mua o ka ʻole, ʻeā?

ʻOkoʻa ka hana ʻana o nā paneli Thermoradiant i ka uila ma mua o nā panela lā. I nā paneli maʻamau, ʻike ʻia ka mālamalama ʻike ma ke ʻano o nā photons e komo i ka semiconductor o ka photocell a pili pū me ka mea waiwai. hoʻoili i kona ikaika iā ia. ʻO nā mea thermoradiation i manaʻo ʻia e ka poʻe ʻepekema e hana ma ke ʻano like, hoʻohana wale lākou i ka ikehu o ka radiation infrared. Ua like ka physics, akā, ʻokoʻa nā mea i loko o nā mea, e like me ka ʻōlelo a nā ʻepekema ma ka ʻatikala pili i ka puke pai. ACS Photonics.

ʻO ka nīnau e pili ana i ka hana o ka mea thermoradiation i ke ao e wehe ʻia, ʻoiai hiki ke hana ʻia nā kūlana no kāna hana i ka lā. I ka pō, ʻo ka mea thermoradiation, wela i ke ao, e hoʻomālamalama ikaika i ka wela i hōʻiliʻili ʻia i kahi ākea ākea. I ke kaʻina hana o ka radiation infrared i loko o ka mea o ka mea thermoradiation, ua hoʻololi ʻia ka ikehu o nā mea i hoʻokuʻu ʻia i ka ikehu uila. Ma ke kumu, hiki i ia mea hoʻololi ke hoʻomaka e hana i ka wā e hāʻule ai ka mahana ambient ma lalo o kona wahi mehana.

I kēia manawa, ʻaʻole mākaukau nā ʻepekema e hōʻike i kahi prototype o kahi mea thermoradiation a ke hoʻokokoke wale nei i kāna hana. ʻAʻohe ʻikepili e pili ana i kahi mea e makemake ai no ka hana ʻana i nā mea thermoradiation. Ke kamaʻilio nei ka ʻatikala e pili ana i ka hoʻohana ʻana i nā mea hoʻohui mercury, kahi e noʻonoʻo ai mākou i ka palekana. I ka manawa like, he mea hoʻowalewale ka loaʻa ʻana o nā cell i hiki ke hoʻohua i ka uila ʻaʻole wale i ka lā, akā i ka pō.
