Amaphampu okushisa omhlaba (GHPs), kwesinye isikhathi abizwa ngokuthi ama-GeoExchange, amaphampu okushisa ahlanganisiwe emhlabeni, avela phansi, noma omthombo wamanzi, abelokhu esetshenziswa kusukela ngasekupheleni kwawo-1940s. Basebenzisa izinga lokushisa elingaguquki lomhlaba njengendawo yokushintshanisa esikhundleni sezinga lokushisa lomoya wangaphandle.
Nakuba izingxenye eziningi zezwe ziba nezinga lokushisa elishisayo lesizini - kusukela ekushiseni okushisayo ehlobo kuya kubanda kakhulu ebusika.- amafidi ambalwa ngaphansi kobuso bomhlaba umhlaba uhlala usezingeni lokushisa elingashintshi. Ngokuya nge-latitude, amazinga okushisa asuka ku-45°F (7°C) kuya ku-75°F (21° C). Njengomhume, lokhu kushisa komhlabathi kufudumele kunomoya ongaphezu kwawo ebusika futhi kupholile kunomoya ehlobo. I-GHP isebenzisa lawa mazinga okushisa avumayo ukuze isebenze kahle kakhulu ngokushintshanisa ukushisa nomhlaba ngesishintshi sokushisa esiphansi.
Njenganoma iyiphi impompo yokushisa, amaphampu okushisa e-geothermal nawemithombo yamanzi ayakwazi ukufudumeza, ukupholisa, futhi, uma efakwe kanjalo, anikeze indlu ngamanzi ashisayo. Amanye amamodeli wesistimu ye-geothermal ayatholakala ngama-compressor amasivinini amabili namafeni ahlukile ukuze uthole ukunethezeka okwengeziwe nokonga amandla. Ngokuphathelene namaphampu okushisa omthombo womoya, athule, ahlala isikhathi eside, adinga ukulungiswa okuncane, futhi awancikile ekushiseni komoya wangaphandle.
Iphampu yokushisa enemithombo emibili ihlanganisa iphampu yokushisa yomthombo womoya kanye nephampu yokushisa ye-geothermal. Lezi zisetshenziswa zihlanganisa okuhle kakhulu kuwo womabili amasistimu. Amaphampu okushisa anemithombo emibili anezilinganiso zokusebenza kahle kakhulu kunamayunithi omthombo womoya, kodwa awasebenzi kahle njengamayunithi we-geothermal. Inzuzo enkulu yamasistimu anemithombo emibili ukuthi abiza kancane kakhulu ukuwafaka kuneyunithi eyodwa ye-geothermal, futhi asebenza cishe ngokufanayo.
Ngisho noma intengo yokufaka yesistimu ye-geothermal ingaba izikhathi ezimbalwa kunesistimu yomthombo womoya womthamo ofanayo wokushisisa nokupholisa, izindleko ezengeziwe zingabuyiswa ngokongiwa kwamandla eminyakeni emi-5 ukuya kweyi-10, kuye ngezindleko zamandla kanye izikhuthazo ezitholakalayo endaweni yangakini. Impilo yesistimu ilinganiselwa eminyakeni engama-24 ezingxenyeni zangaphakathi kanye neminyaka engama-50+ ku-loop yaphansi. Kukhona cishe amaphampu okushisa e-geothermal angaba ngu-50,000 afakwa e-United States unyaka ngamunye.
