Thermoelectric friji

Kuwonekera kwa mitundu yatsopano ya zipangizo zam'nyumba zodziwika bwino nthawizonse kumagwirizana ndi kupereka chitetezo chaumwamba cha anthu ndi nthawi zonse pofuna kukwanitsa zofuna zake. Zili ndi cholinga chakuti malingaliro opangidwa ndi mafakitale omwe ali ndi kutentha kwa thermoelectric aonekera pa msika wa mdziko umene ungapereke mankhwala ndi zakumwa kunja kwa nyumba: paulendo kapena pa picnic.

Kodi firiji ya thermoelectric imagwira ntchito bwanji?

Ntchito yogwiritsira ntchito firiji iliyonse imakhala yogwiritsa ntchito Peltier Effect. Zimaphatikiziranso kuti pakali pano pakadutsa mpweya wotchedwa thermobattery, womwe uli ndi machitidwe awiri osiyana (ogwirizana mu mndandanda), kutentha kumatulutsidwa kapena kutengeka pamalo pomwe iwo akugwirizanitsa (malingana ndi momwe akuchitira panopa), mwachitsanzo. Kutentha kwa kutentha kumachitika kuti mbali imodzi ya bateri imakumba ndipo ina imatenthedwa.

Pofuna kugwiritsa ntchito izi, mbali yoyamba (yozizira) ya thermobattery imayikidwa mkati, yomwe imayenera kutenthedwa, ndipo yachiwiri (yotentha) - kumalo ozungulira.

Chipangizo cha firiji ndi kutentha kwa thermoelectric:

1. Fan - chifukwa cha kutaya kwa kutentha.
2. Radiator ndi mapulogalamu a aluminiyumu opangidwa ndi finali kuti azitulutsa kutentha.
3. Wotulutsa - kutulutsa chimfine mkati mwa firiji.
4. Mphamvu - kusintha mphamvu ya AC kuti ikhale yosasinthika.
5. Sinthani magetsi - njira ziwiri: kuyambira 0 mpaka 5 ° C ndi 8 mpaka 12 ° C. 6. Thupi ndi chivindikiro.

Zonsezi zimaphatikizidwa kumbuyo kwa nkhaniyi kapena zili mu chivindikiro cha firiji

Mitundu ya ozizira thermoelectric

Pali mitundu iwiri yowonongeka yotentha ya thermoelectric:

• kwa magalimoto;
• mwa mawonekedwe a thumba.

Magalimoto otentha firiji

Amagwiritsa ntchito magalimoto ndi magalimoto kuti azizizira (kapena kutenthetsa) ndi kusunga zakudya ndi zakumwa pamene akuyendetsa galimoto kapena kupaka. Firijiyi imayikidwa mu kanyumba ya galimotoyo, ndipo nthawi zina imatha kugwira ntchito.

Amapanga mafiriji awiri omwe amasinthidwa: Amagwiritsidwa ntchito kuchokera ku maunyolo kufika 12 V ndi 24 V, ndipo pogwiritsa ntchito chipangizo chobwezera, akhoza kugwirizanitsidwa ndi 220 V kapena 127 V network. Nthawi yoperekera malire imakhala yopanda malire, koma mwachibadwa, yokhala ndi nthawi zonse. Chophimba chakunja cha firiji choterechi chimadzazidwa ndi chikopa chakuda chophimba pamwamba pa chitsulo chokongoletsera, ndipo mkati mwake kumakhala ndi aluminiyamu ya zakudya. Kutsekemera kwa kutentha kumaperekedwa ndi polystyrene yowonjezeredwa. Ipezeka mu mitundu yosiyanasiyana:

• bokosi lomwe linapangidwa kukhala niche yapadera;
• tebulo laling'ono kapena gome la pambali;
• mini-friji (kwa mtsuko ndi zakumwa).

Chikwama chozizira chimbudzi

Njira yabwino kwambiri ya firiji yowonongeka, yomwe imakupatsani chisudzo chozizira ndi chakudya mukutentha. Kuti mupeze firiji yotentha mu firiji, ndi bwino kuika zonse mufiriji kale, ndipo mukhoza kuika muzizira zozizira , matumba a chipale kapena mbale zowonongeka. Ngati mukufuna chipangizochi chitha kugwira ntchito komanso ngati thermos, kuti muthetse kutentha kwa mankhwala.

Mosiyana ndi galimoto, thumba la firiji silinakonzedwe kutentha chakudya.

Mu chikwama cha thumba ndikuwonjezera:

• chingwe chautali kuti apange firiji mu thunthu;
• zophimba ziwiri: imodzi ndi zingwe ndi chosinthana, china chimakhala ndi chogwirira (chonyamula.

Ubwino wa firiji ya thermoelectric

• chisokonezo;
• kudalirika ndi kukhazikika;
• kukula kochepa;
• Kusasunthika, kusakaniza mbali ndi zovuta kugwirizanitsa mapaipi;
• kuthekera kwachindunji kuteteza kutentha;
• palibe kusowa kwa madzi kapena mpweya ozizira.

Koma, ngakhale kupindula ndi kutuluka kwa mafiriji a thermoelectric, sali otchuka kwambiri chifukwa cha mtengo wapamwamba.
