He aha ka ʻokoʻa ma waena o ka pahu hau lāʻau lapaʻau a me ka pahu hau hale

Ua kamaʻāina loa nā kānaka i nā pahu hau o ka hale. ʻO lākou nā lako hale i hoʻohana nui ʻia i kēlā me kēia lā. ʻOiai ʻo kanā pahu hau lāʻau lapaʻauʻaʻole i hoʻohana nui ʻia e nā ʻohana. I kekahi manawa hiki iā ʻoe ke ʻike i kekahi puka anianinā pahu hau lāʻau lapaʻauma nā hale kūʻai lāʻau lapaʻau. ʻO kēlā mau meanā pahu hau lāʻau lapaʻauʻo ka maʻamau ua lako me nā puka aniani moakaka, mālamalama a ʻaʻohe hau ma nā puka a i ʻole ma kahi o loko. Hōʻike maikaʻi kēia i ke ʻano o ka ʻokoʻa ma waenanā pahu hau lāʻau lapaʻaua me nā pahu hau o ka hale. Eia nō naʻe, makemake wau e hōʻuluʻulu i nā ʻokoʻa ʻano hou aʻe ma ka hoʻohālikelike ʻana i kēia mau pūʻulu ʻelua o nā pahu hau.

 

 

 

Mahana

 

Hiki ke mālama ʻia nā lāʻau lapaʻau maʻamau i ka mahana o ka lumi ma waena o 15°C a me 25°C (59°F a i 77°F), ma kahi anu a maloʻo, akā e ʻoluʻolu e hahai pono i kā lākou mau ʻōlelo kuhikuhi no ka mālama ʻana.Nā pahu hau lāʻau lapaʻaupono e mālama i ka mahana ma waena o 2°C a me 8°C (36°F a me 46°F). He pae mahana paʻa kēia e ʻae ai i nā loli liʻiliʻi ma muli o ka wehe ʻia ʻana o ka puka. ʻO kahi hoʻonohonoho waena o 5°C (41°F) he lula maikaʻi ia o ka manamana lima. ʻAʻole pono e hoʻopaʻahau ʻia nā lāʻau lapaʻau i loko o ka pahu hau.

 

 

ʻAno Hoʻonohonoho Mahana

 

ʻO ka thermostat kikohoʻe, i kapa ʻia hoʻi he thermostat uila, hāʻawi i ka kaohi mahana pololei i nā pahu hau ma mua o ka thermostat mechanical. Hoʻohana pū kekahi mau pahu hau home i ka thermostat kikohoʻe akā hoʻohana nā pahu hau lapaʻau āpau i nā thermostat kikohoʻe. He mea koʻikoʻi ka kaohi mahana pololei no ka mea pono e mālama ʻia nā lāʻau pale a me nā lāʻau lapaʻau i nā mahana kikoʻī, me ka liʻiliʻi o ka loli. Loaʻa pū ka hapa nui o nā pahu hau lapaʻau me kahi hōʻike mahana waho pololei e hiki ai i nā kānaka ke ʻike i ka mahana kūloko pololei me ka ʻole o ka wehe ʻana i ka pahu hau. Hiki i kēia hōʻike ke hōʻike i nā mahana kūloko haʻahaʻa a me ka kiʻekiʻe loa a me ka mahana o kēia manawa. Hoʻolako ʻia kēia ʻano pahu hau lapaʻau me ka mea hoʻopaʻa ʻikepili a i ʻole ka mea hoʻopaʻa pakuhi mechanical no ka hoʻopaʻa ʻana i ka mahana.

 

Eia kekahi, ʻokoʻa hoʻi kā lākou mau hoʻonohonoho mahana. Loaʻa i nā pahu hau hale kahi pae mahana i ʻae ʻia, ʻoiai he nui nā pahu hau lapaʻau i loaʻa kahi ākea o nā mahana i loaʻa. Hoʻokipa kēia i nā mea e pono ai ke mālama ʻia i nā mahana anuanu loa. Hoʻopili pinepine ʻia nā champer anuanu i loko o nā pahu hau lapaʻau i nā mahana e like me -20 °C, -40 °C a i ʻole -80 °C. ʻOiai ʻo nā pahu hau hale ka maʻamau he -18 °C ka mahana haʻahaʻa.

Hoʻohana nā pahu hau ʻohana i ka ʻōnaehana hoʻoluʻu pololei a i ʻole ka ʻōnaehana hoʻoluʻu ea. Akā, hoʻohana nā pahu hau lapaʻau a pau i ka hoʻoluʻu ea, a hoʻohana kekahi o lākou i ka hoʻoluʻu ea i hoʻoikaika ʻia. Hiki i ka hoʻoluʻu pololei ke hana i nā mahana like ʻole ma loko o ka lua. No laila, ʻaʻole koho ka hoʻoluʻu pololei no ka pahu hau lapaʻau. I loko o ka ʻōnaehana hoʻoluʻu ea, kōkua nā peʻahi ikaika e hoʻemi koke i ka mahana ma hope o ka wehe ʻia ʻana o ka puka. Loaʻa i nā pahu hau lapaʻau nā papa uea e hoʻonui ai i ke kahe ʻana o ka ea, ʻoiai he mau papa aniani a plastik paha nā pahu hau ʻohana i maʻalahi ke hoʻomaʻemaʻe akā ālai i ka ea. Hoʻonohonoho ʻia hoʻi ka ducting ma nā pahu hau lapaʻau no ke kūlike o ka mahana, i hoʻolālā ʻia e mālama i ka mahana e like me ka hiki i kahi i hoʻonohonoho ʻia ai. Loaʻa i nā pahu hau ʻohana nā ʻōpala crisper, ʻoiai he mea pono no ka mālama ʻana i ka meaʻai, ālai pū i ke kahe ʻana o ka ea a hana i nā wahi ʻeleʻele mahana.

Loaʻa i nā pahu hau lapaʻau nā puka pani ponoʻī a me nā ʻōuli puka koʻikoʻi loa no ka mea ʻo ka waiho ʻana i ka puka o ka pahu hau lapaʻau e hāmama ana hiki ke lilo i mea pōʻino maoli a loaʻa nā hopena mau loa i ke olakino o nā haneli o nā maʻi. ʻAʻole loaʻa i nā pahu hau hale kēia mau hiʻohiʻona. He mea maʻamau nō hoʻi no nā pahu hau lapaʻau ke loaʻa nā laka kī ma ko lākou mau puka, he ʻano kakaikahi loa ia i nā pahu hau hale, a me nā pedal puka e wehe ai. Loaʻa i nā pahu hau hale nā ​​plug maʻamau hiki ke wehe maʻalahi ʻia mai nā paia, ʻoiai ʻo nā pahu hau lapaʻau he mau plug "kiko ʻōmaʻomaʻo" a me nā kaula pae lapaʻau e mālama i ke kahe mana. Loaʻa i nā pahu hau lapaʻau nā sila kiʻekiʻe ma ko lākou mau puka, e pale ana i ke komo ʻana o ka ea i loko.
