Amaphampu okushisa angaphansi komthombo
Amaphampu okushisa omthombo ophansi asebenzisa umhlaba noma amanzi angaphansi njengomthombo wamandla ashisayo kumodi yokushisisa, nanjengosinki ukuze enqabe amandla lapho ekwimodi yokupholisa. Lezi zinhlobo zamasistimu ziqukethe izingxenye ezimbili ezibalulekile:
- I-Ground Heat Exchanger: Lesi isishintshi sokushisa esisetshenziselwa ukwengeza noma ukususa amandla ashisayo emhlabeni noma emhlabathini. Ukucushwa okuhlukahlukene kwesishintshi sokushisa kungenzeka, futhi kuchazwe kamuva kulesi sigaba.
- Iphampu Yokushisa: Esikhundleni somoya, amaphampu okushisa omthombo waphansi asebenzisa uketshezi olugeleza kwisishintshi sokushisa esiphansi njengomthombo wawo (ekushiseni) noma usinki (ekupholiseni).
Ohlangothini lwesakhiwo, zombili izinhlelo zomoya kanye ne-hydronic (zamanzi) zingenzeka. Amazinga okushisa okusebenza ohlangothini lwesakhiwo abaluleke kakhulu ekusetshenzisweni kwe-hydronic. Amaphampu okushisa asebenza kahle kakhulu lapho eshisisa emazingeni okushisa aphansi angaphansi kuka-45 kuya ku-50°C, okuwenza afanelane kangcono nephansi elikhazimulayo noma amasistimu wamakhoyili efeni. Kufanele kuqashelwe uma kucatshangelwa ukusetshenziswa kwawo nama-radiator okushisa aphezulu adinga amazinga okushisa amanzi angaphezu kuka-60°C, njengoba lawa mazinga okushisa ngokuvamile edlula imikhawulo yamaphampu okushisa amaningi okuhlala.
Ngokuya ngokuthi iphampu yokushisa kanye nesishintshi sokushisa esiphansi zisebenzisana kanjani, izigaba ezimbili ezihlukene zesistimu zingenzeka:
- Iluphu yesibili: Uketshezi (amanzi angaphansi komhlaba noma i-anti-freeze) isetshenziswa kusishintshi sokushisa esiphansi. Amandla ashisayo adluliswa esuka phansi kuya oketshezini alethwa epompo yokushisa ngesishintshi sokushisa.
- Ukunwetshwa Okuqondile (DX): Isiqandisi sisetshenziswa njengoketshezi esitsheni sokushisa esiphansi. Amandla okushisa akhishwa yisiqandisi emhlabathini asetshenziswa ngokuqondile iphampu yokushisa - akukho mshini wokushisa owengeziwe odingekayo.
Kulezi zinhlelo, isishintshi sokushisa esiphansi siyingxenye yephampu yokushisa ngokwayo, esebenza njenge-evaporator kumodi yokushisisa kanye ne-condenser kumodi yokupholisa.
Amaphampu okushisa omthombo ophansi anganikeza izidingo zokunethezeka ekhaya lakho, okuhlanganisa:
- Ukushisisa kuphela: Iphampu yokushisa isetshenziswa kuphela ekushiseni. Lokhu kungabandakanya kokubili ukushisisa isikhala nokukhiqizwa kwamanzi ashisayo.
- Ukushisisa “ngokupholisa okusebenzayo”: Iphampu yokushisa isetshenziswa kukho kokubili ukushisisa nokupholisa
- Ukushisisa “ngokupholisa okwenziwayo”: Iphampu yokushisa isetshenziswa ekushisiseni, futhi yeqe ekupholiseni. Ekupholiseni, uketshezi oluphuma esakhiweni lupholiswa ngokuqondile kusishintshi sokushisa esiphansi.
Ukushisisa kanye “nokupholisa okusebenzayo” kuchazwa esigabeni esilandelayo.
Izinzuzo Ezinkulu ze-Ground-Source Heat Pump Systems
Ukusebenza kahle
E-Canada, lapho izinga lokushisa lomoya lingehlela ngaphansi kuka-30°C, amasistimu omthombo ophansi ayakwazi ukusebenza kahle kakhulu ngoba asebenzisa ngokunenzuzo amazinga okushisa aphansi futhi azinze kakhudlwana. Amazinga okushisa avamile amanzi angena empompini yokushisa yomthombo waphansi ngokuvamile angaphezulu kuka-0°C, anikeza i-COP ecishe ibe ngu-3 kumasistimu amaningi phakathi nezinyanga zasebusika ezibanda kakhulu.
Ukonga Amandla
Amasistimu omthombo ophansi azokwehlisa izindleko zakho zokushisisa nokupholisa kakhulu. Ukonga kwezindleko zamandla okushisisa uma kuqhathaniswa neziko likagesi cishe ku-65%.
Ngokwesilinganiso, isistimu yomthombo waphansi eklanywe kahle izoletha ukonga okucishe kube ngu-10-20% ngaphezu kwalokho obekungahlinzekwa yiphampu yokushisa yomthombo womoya obandayo ehamba phambili ekilasini enosayizi wokuvala ingxenye enkulu yomthwalo wokushisisa isakhiwo. Lokhu kungenxa yokuthi amazinga okushisa angaphansi komhlaba aphezulu ebusika kunamazinga okushisa omoya. Ngenxa yalokho, iphampu yokushisa yomthombo ophansi inganikeza ukushisa okwengeziwe phakathi nobusika kunepompo yokushisa yomthombo womoya.
Ukonga kwangempela kwamandla kuzohluka kuye ngesimo sezulu sasendaweni, ukusebenza kahle kwesistimu yokushisisa ekhona, izindleko zikaphethiloli nogesi, usayizi wephampu yokushisa efakiwe, ukumiswa kwe-borefield kanye nebhalansi yamandla yesizini, kanye nokusebenza kahle kwephampu yokushisa e-CSA. izimo zokulinganisa.
Isebenza Kanjani Isistimu Yomthombo Ophansi?
Amaphampu okushisa omthombo waphansi ahlanganisa izingxenye ezimbili eziyinhloko: Isishintshi sokushisa esiphansi, kanye nephampu yokushisa. Ngokungafani namaphampu okushisa omthombo womoya, lapho isishintshi sokushisa esisodwa sitholakala ngaphandle, kumasistimu omthombo ophansi, iyunithi yepompo yokushisa itholakala ngaphakathi kwekhaya.
Imiklamo ye-Ground exchanger ingahlukaniswa ngokuthi:
- Iluphu evaliwe: Amasistimu amaluphu avaliwe aqoqa ukushisa okuvela phansi ngokusebenzisa iluphu eqhubekayo yamapayipi agqitshwe ngaphansi. Isixazululo se-antifreeze (noma isiqandisi esimweni sesistimu yomthombo waphansi we-DX), esifakwe isistimu yesiqandisi sephampu yokushisa sibe ngamadigri ambalwa okubanda kunenhlabathi engaphandle, sizungeza kumapayipi futhi simunca ukushisa emhlabathini.
Amalungiselelo amapayipi avamile ezinhlelweni eziluphu ezivaliwe ahlanganisa izinhlelo ezivundlile, eziqondile, ezidayagonali kanye nezamachibi/echibini (lezi zinhlelo kuxoxiswana ngazo ngezansi, ngaphansi Kokucatshangelwa Kwedizayini). - I-Open Loop: Amasistimu avuliwe asebenzisa ukushisa okugcinwe emanzini angaphansi komhlaba. Amanzi adonswa emthonjeni aqonde emshinini wokushisisa, lapho kukhishwa khona ukushisa kwawo. Amanzi abe esechithelwa emanzini angaphezulu komhlaba, njengomfudlana noma echibini, noma abuyele emanzini afanayo angaphansi komhlaba ngomthombo ohlukile.
Ukukhethwa kwesistimu yamapayipi angaphandle kuncike esimweni sezulu, izimo zenhlabathi, umhlaba otholakalayo, izindleko zokufakwa kwendawo endaweni kanye nemithetho kamasipala neyesifundazwe. Isibonelo, amasistimu e-loop avulekile avunyelwe e-Ontario, kodwa awavunyelwe e-Quebec. Abanye omasipala bavimbele izinhlelo ze-DX ngenxa yokuthi umthombo wamanzi kamasipala yi-aquifer.
Umjikelezo Wokushisa
Phawula:
Ezinye zezihloko zithathwe ku-inthanethi. Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze ukususe. Uma uthanda imikhiqizo yephampu yokushisa, sicela ukhululeke ukuxhumana nenkampani yephampu yokushisa ye-OSB, siyisinqumo sakho esingcono kakhulu.
