Ezihlokweni ezedlule sikhulume ngazo Ukushisa kwe-geothermal. Kuyo, sakhuluma ngesinye sezinto ezidingekayo zokusebenzisa lolu hlobo lokushisa futha ukushisa geothermal. Ukusebenza kwayo kuyefana nokwempompo evamile yokushisa. Noma kunjalo, amandla okushisa ayisebenzisayo akhishwa emhlabathini.
Ngabe ufuna ukwazi ngokujula ukusebenza nezimpawu zepompo yokushisa kwe-geothermal? Lolu lwazi lungasiza kakhulu uma uzofaka ukufudumeza ekhaya lakho 🙂
Impompo yokushisa kwe-geothermal
Ukuvuselela imiqondo kancane futhi sisebenzise yonke i-athikili kahle, sizobuyekeza incazelo yokushisa kwe-geothermal. Luhlelo lokushisa lapho sisebenzisa khona amanzi ashisayo ukushisa ingaphakathi lesakhiwo. Lokho kushisa kuvela emadwaleni noma emanzini angaphansi komhlaba futhi uyakwazi ukusebenzisa i-generator kagesi. Kungumqondo, ngakho-ke, emkhakheni wamandla we-geothermal.
Iphampu yokushisa kwe-geothermal ingasebenza noma kuphi. Lokhu kusetshenziswa bekusakazeka kuwo wonke umphakathi, kufinyelela ezingeni lokuthi ikhula ngama-20% minyaka yonke. Lapho sithinta amashubhu ngemuva kwesiqandisisi, siyabona ukuthi ukushisa kumuncwa kusuka ngaphakathi kukasetshenzisi bese kukukhipha kukhishi lonke. Impompo yokushisa isebenza ngendlela efanayo, kepha ibuyela emuva. Iyakwazi ukuthatha ukushisa okungaphandle futhi ikukhiphele ngaphakathi. Kunjengokungathi uzama ukupholisa ingaphandle.
Ukusebenza
Kuwo womabili amafriji nempompo yokushisa, kunamashubhu ajikelezisa uketshezi lwefriji. Lolu ketshezi luyakwazi ukushisa uma lucindezelwe futhi luphole lapho lunwetshwa. Uma sifuna ukufudumeza indlu ukuze ihlale kahle ebusika, uketshezi olushisayo olucindezelwe luzohamba ngomshini wokushisa oshisa umoya ondla uhlelo oluqhubayo.
Ungathi uketshezi seluvele "lusetshenzisiwe." Ngemuva kwalokho, iyaphola futhi inwebe, ihlangane ne- umthombo we-geothermal "owugcwalisa kabusha" ngokushisa. Le nqubo iphindaphindwa kaninginingi ngokushisa okuqhubekayo.
Into okufanele uyikhumbule ukuthi ukumpompa uketshezi kudinga ugesi. Iphampu yokushisa kwe-geothermal isebenza kahle kakhulu kunamanye amaphampu noma ezinye izindlela zokushisa. Izinhlelo ezikhona njengamanje Bayakwazi ukukhiqiza kuze kufike ku-4 kW wokushisa kuwo wonke ama-kW kagesi akhiqizwayo. Lokhu kuzenza zisebenze kahle kakhulu, ngoba azidingi ukukhiqiza ukushisa, kepha ukuzikhipha ngaphansi komhlaba.
Ngokuphambene nalokho, awekho amaphampu kuphela ashisa indlu. Ungafaka futhi ifriji endlini ukuthi ipholile ngesikhathi sasehlobo. La mapampu abizwa ngokuthi amaphampu okushisa ashintshekayo. Kulokhu, i-valve iyona elawula ukuqondiswa koketshezi. Ngakho-ke, ukushisa kungazungeza ngezindlela ezimbili.
Izindlela zokukhipha amandla we-geothermal
Abantu abaningi abasebenzisa lolu hlobo lokushisa sebevele bajwayele amaphampu okushisa okushisa phansi. Inzuzo enkulu ukusebenzisa umoya ovela ngaphandle ukushisa ikhaya. Ukushisa komhlaba akunamkhawulo, ngakho kubhekwa njengohlobo lwamandla avuselelekayo. Ungaba nokushisa noma kunini lapho ukudinga futhi ngendlela entofontofo kakhulu futhi eshibhile. Ngaphezu kwalokho, uzobe usiza ekunakekeleni imvelo futhi wehlise ukukhishwa kwegesi ekhipha ukushisa emoyeni. Ngale ndlela sizobe sinciphisa imiphumela emibi yokuguquka kwesimo sezulu kanye nokufudumala komhlaba.
Enye yezingqinamba zamaphampu okushisa ajwayelekile ukuthi ukusebenza kwawo kuyancipha lapho izinga lokushisa langaphandle libanda kakhulu. Lokhu kusho ukuthi lapho ukushisa kudingeka kakhulu ngaphakathi ekhaya, ipompo linokusebenza okuncane. Noma kunjalo, lokhu akwenzeki ngepompo yokushisa okushisa phansi, ngoba ikhipha ukushisa kusuka ngaphakathi komhlaba. Ngaphansi komhlaba ukushisa kuzinzile futhi izinga lokushisa lihlala lilingana noma ngabe kubanda ngaphandle. Ngakho-ke, ayilahlekelwa ukusebenza nganoma yisiphi isikhathi.
Kuqondile futhi kuvundlile ukushisa komhlaba okushisa futha
Indlela ethandwa kakhulu yokukhipha ukushisa yimpompo yokushisa eqondile. Imvamisa ifakwa amamitha ayi-150 kuye kwangama-200 ngaphansi kobuso. Amapayipi afakwa azungeze ama-grooves ambiwa ngaphansi komhlaba. Amanzi azungeza ngawo nge-antifreeze fluid eyengeziwe ekwazi ukukhulisa ukushisa ukuze ithole uketshezi olupholile.
Enye indlela iphampu yokushisa evundlile evundlile. Kulokhu, amashubhu agcwaliswa ngamanzi futhi angcwatshwe cishe ngamamitha ayisithupha ngaphansi komhlaba. Yizinhlelo ezidinga ukunwetshwa okukhulu ukuze zikwazi ukukhiqiza ukushisa okufanelekile ukushisa isakhiwo esisemaphakathi. Noma kunjalo, izindleko zayo ziphansi kakhulu kunepompo eqondile.
Abantu abaningi bayangabaza ukusebenza kwayo ezindaweni eziseduze nemithombo yemvelo yamanzi njengamachibi, imifula namachibi. Lokhu akufani nalokhu. Iphampu yokushisa kwe-geothermal isebenza kahle eduze kwalezi zindawo njengoba ungazisebenzisa njengomthombo wokushisa wangaphandle.
Ukushintshaniswa kokushisa nendawo yangaphandle kwenziwa ngomqoqi we-geothermal, ongaba yizinhlobo ezimbili: abaqoqi be-geothermal abemi mpo nabaphezulu. Esimweni sokuqala, ukujikeleza kwamashubhu (2 noma 4) kufakwa ngaphakathi kwe-perforation to 50-100 m ukujula nobubanzi obungu-110-140 mm. Esimweni sesibili, inethiwekhi evundlile yamapayipi ibekwa ekujuleni okungu-1,2-1,5 m.
Ukutshalwa kwezimali kokuqala
Isithiyo esikhulu esime endleleni yokusebenzisa amandla avuselelekayo wukutshalwa kwezimali kokuqala. Njengasemikhakheni eminingi, kuyadingeka ukuthi utshale imali ekuqaleni bese uyihlela ngokuhamba kwesikhathi. Izindleko zokuqala zokushisa kwe-geothermal zidlula ezamasistimu wokushisa wendabuko.
Uma kuhloselwe ukwakha ngaphakathi ikhaya lomndeni lingabiza phakathi kwama-euro ayizi-6.000 nangu-13.000. Lokhu umbhedo kubo bonke labo bantu umsebenzi wabo ongabatholi amaholo amakhulu. Ngaleyo mali ungathenga imoto! Kodwa-ke, amaphampu okushisa we-geothermal anenzuzo ngokuhamba kwesikhathi. Bavumela ukunciphisa ukusetshenziswa komthethosivivinywa wamandla phakathi kuka-30 no-70% esimweni sokushisa kanye no-20-50% ekupholiseni.
Ngiyethemba ukuthi ngalolu lwazi usukulungele ukusebenzisa lolu hlobo lokushisa bese uqala ukonga manje.
