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 nezimo ezicindezelayo zokushisa kwezinkathi ezithile zonyaka - kusukela ekushiseni okushisayo ehlobo kuye kumakhaza angaphansi kwezinga-qhwa ebusika—amafidi ambalwa ngaphansi kobuso bomhlaba umhlaba uhlala usezingeni lokushisa elingashintshi. Ngokuya ngobubanzi, 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.
Izinhlobo ze-Geothermal Heat Pump Systems
Kunezinhlobo ezine eziyisisekelo zezinhlelo ze-ground loop. Okuthathu kwalokhu - okuvundlile, okuqondile, kanye nechibi/ichibi - kuyizinhlelo ezivaliwe. Uhlobo lwesine lwesistimu inketho ye-open-loop. Izici eziningana ezifana nesimo sezulu, izimo zenhlabathi, umhlaba otholakalayo, nezindleko zokufakwa kwendawo zinquma ukuthi yikuphi okungcono kakhulu kwesiza. Zonke lezi zindlela zingasetshenziselwa izicelo zokwakha zokuhlala nezohwebo.
I-Closed-Loop Systems
Amaphampu amaningi okushisa ohlobo lwe-geothermal avaliwe azungeza isixazululo se-antifreeze ngokusebenzisa iluphu evaliwe - ngokuvamile eyenziwe ngamashubhu ohlobo lwepulasitiki aminyana kakhulu - agqitshwe phansi noma acwiliswe emanzini. Isishintshi sokushisa sidlulisa ukushisa phakathi kwesiqandisi empompini yokushisa kanye nesixazululo se-antifreeze ku-loop evaliwe.
Olunye uhlobo lwesistimu eyiluphu evaliwe, ebizwa ngokuthi i-direct exchange, ayisebenzisi isishintshi sokushisa futhi esikhundleni salokho iphampa isiqandisi ngamashubhu ethusi agqitshwe emhlabathini ngokuvundlile noma ukumiswa okuqondile. Izinhlelo zokushintshisana ngqo zidinga i-compressor enkulu futhi zisebenza kahle enhlabathini emanzi (ngezinye izikhathi zidinga ukuchelelwa okwengeziwe ukuze inhlabathi ihlale imanzi), kodwa kufanele ugweme ukufaka enhlabathini egqwala kumashubhu ethusi. Ngenxa yokuthi lezi zinhlelo zizungeza isiqandisi phansi, imithetho yendawo yendawo ingase ivimbele ukusetshenziswa kwazo kwezinye izindawo.
Evundlile
Lolu hlobo lokufakwa ngokuvamile luyonga kakhulu ukufakwa kwendawo yokuhlala, ikakhulukazi ukwakhiwa okusha lapho kutholakala indawo eyanele. Idinga imisele okungenani amafidi amane ukujula. Izakhiwo ezivame kakhulu zisebenzisa amapayipi amabili, elinye ligqitshwe ngamafidi ayisithupha, kanti elinye lingamamitha amane, noma amapayipi amabili abekwe ngapha nangapha ngamamitha amahlanu emhlabathini emiseleni engamafidi amabili ububanzi. Indlela ye-Slinky™ yokuluphu ipayipi ivumela ipayipi elengeziwe kumsele omfushane, owehlisa izindleko zokufakwa futhi wenze ukufakwa okuvundlile kwenzeke ezindaweni lapho kungeke kube khona izinhlelo zokusebenza ezivundlile ezivamile.
