Pampu yotentha yapansi panthaka

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 dzikolo amakhala ndi kutentha kwambiri kwa nyengo - kuchokera pa kutentha kotentha m'chilimwe mpaka kuzizira kwambiri m'nyengo yozizira.- mamita angapo pansi pa nthaka nthaka imakhalabe pa kutentha kosasintha. Kutengera latitude, kutentha kwa nthaka kumachokera pa 45°F (7°C) mpaka 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.
