Mapampu Otentha a Geothermal——Gawo 1

Mapampu otentha a Geothermal (GHPs), omwe nthawi zina amatchedwa GeoExchange, earth-coupled, ground-source, kapena madzi-source heat pumps, akhala akugwiritsidwa ntchito kuyambira kumapeto kwa zaka za m'ma 1940. Amagwiritsa ntchito kutentha kosasinthasintha kwa dziko lapansi monga njira yosinthira m'malo mwa kutentha kwakunja kwa mpweya.

Ngakhale kuti madera ambiri a dzikoli amakhala ndi kutentha kwanyengo kwa nyengo—kuchokera pa kutentha kotentha m’chilimwe mpaka kuzizira kwambiri m’nyengo yachisanu—mamita angapo pansi pa dziko lapansi, nthaka imakhalabe yotentha kwambiri. Malingana ndi latitude, kutentha kwa nthaka kumachokera pa 45°F (7°C) kufika pa 75°F (21°C). Mofanana ndi phanga, kutentha kwa nthaka kumeneku kumakhala kotentha kwambiri kuposa mpweya umene umatuluka pamwamba pake m’nyengo yachisanu ndiponso kuzizira kuposa mpweya wa m’chilimwe. GHP imapezerapo mwayi pa kutentha kwabwino kumeneku kuti igwire bwino ntchito posinthanitsa kutentha ndi dziko lapansi kudzera mu chotenthetsera chapansi.

Mofanana ndi pampu iliyonse yotentha, mapampu otentha a geothermal ndi madzi amatha kutentha, kuziziritsa, ndipo, ngati ali ndi zida, amapereka nyumbayo ndi madzi otentha. Mitundu ina yamakina a geothermal ikupezeka ndi ma compressor othamanga awiri komanso mafani osinthika kuti mutonthozedwe komanso kupulumutsa mphamvu. Poyerekeza ndi mapampu otentha omwe amachokera ku mpweya, amakhala chete, amakhala nthawi yayitali, safuna chisamaliro chochepa, ndipo samatengera kutentha kwa mpweya wakunja.

Pampu yotentha yamitundu iwiri imaphatikiza pampu yotentha yochokera ku mpweya ndi pampu ya kutentha kwa geothermal. Zidazi zimaphatikiza machitidwe abwino kwambiri. Mapampu otenthetsera amitundu iwiri ali ndi mphamvu zambiri kuposa magwero a mpweya, koma sagwira bwino ntchito ngati mayunitsi a geothermal. Ubwino waukulu wamakina amitundu iwiri ndikuti amawononga ndalama zochepa kwambiri kuyika kuposa gawo limodzi la geothermal unit, ndipo amagwiranso ntchito mofananamo.

Ngakhale mtengo woyika ma geothermal system ukhoza kuwirikiza kangapo kuposa wa makina opangira mpweya omwe amatenthetsa ndi kuziziritsa komweko, ndalama zowonjezerazo zitha kubwezeredwa pakupulumutsa mphamvu pakadutsa zaka 5 mpaka 10, kutengera mtengo wamagetsi ndi zolimbikitsa zomwe zilipo m'dera lanu. Moyo wadongosolo umayerekezedwa mpaka zaka 24 pazinthu zamkati ndi zaka 50+ za loop yapansi. Pali pafupifupi 50,000 mapampu otentha a geothermal omwe amaikidwa ku United States chaka chilichonse.

Mitundu ya Geothermal Heat Pump Systems

Pali mitundu inayi yofunikira ya machitidwe ozungulira. Atatu mwa awa - opingasa, ofukula, ndi dziwe/nyanja - ndi machitidwe otsekeka. Mtundu wachinayi wa dongosolo ndi njira yotseguka. Zinthu zingapo monga nyengo, nthaka, malo omwe alipo, ndi ndalama zoyikirako zimatsimikizira chomwe chili chabwino pa malowo. Njira zonsezi zitha kugwiritsidwa ntchito pomanga nyumba ndi malonda.

Njira Zotseka-Loop

Mapampu ambiri otsekeka a geothermal otentha amazungulira njira yoletsa kuzizira kudzera pa chipika chotsekedwa - chomwe nthawi zambiri chimapangidwa ndi machubu amtundu wa pulasitiki - omwe amakwiriridwa pansi kapena kumizidwa m'madzi. Chosinthitsa kutentha chimasamutsa kutentha pakati pa firiji mu mpope wa kutentha ndi njira yothira kuzizira mu lupu lotsekedwa.

Mtundu umodzi wa makina otsekedwa, otchedwa kusinthana kwachindunji, sagwiritsa ntchito chowotcha kutentha ndipo m'malo mwake amapopera firiji kudzera m'machubu amkuwa omwe amakwiriridwa pansi mopingasa kapena moyima. Njira zosinthirana mwachindunji zimafunikira kompresa yokulirapo ndipo zimagwira ntchito bwino mu dothi lonyowa (nthawi zina zimafuna kuthirira kowonjezera kuti nthaka ikhale yonyowa), koma muyenera kupewa kuyika mu dothi lowononga machubu amkuwa. Chifukwa makinawa amazungulira mufiriji pansi, malamulo amderalo amatha kuletsa kugwiritsidwa ntchito kwawo m'malo ena.

Chopingasa

Kuyika kwamtunduwu nthawi zambiri kumawononga ndalama zambiri pomanga nyumba, makamaka pomanga kumene komwe kuli malo okwanira. Pamafunika ngalande zakuya zosachepera mapazi anayi. Masanjidwe ambiri amagwiritsira ntchito mipope iwiri, imodzi yokwiriridwa pa mapazi asanu ndi limodzi, ndi inayi mamita anayi, kapena mipope iwiri imayikidwa mbali ndi mbali pa mapazi asanu pansi mu ngalande ya mamita awiri. Njira ya Slinky™ yodulira chitoliro imalola chitoliro chochulukira mumchenga wamfupi, womwe umachepetsa mtengo woyika ndikupangitsa kuti kuyika kopingasa kutheke m'malo omwe sikungakhale ndi ntchito zopingasa wamba.

Zina mwazolemba zatengedwa pa intaneti. Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse. Ngati inu'ndikusangalala ndipansi gwero kutentha mpopemankhwala,chonde omasuka kulankhula ndi OSB kutentha mpope kampani,Mundi chisankho chanu chabwino.
