Pampu Zotentha Zochokera Pansi
Mapampu otentha apansi panthaka amagwiritsa ntchito nthaka kapena madzi apansi ngati gwero la mphamvu zotenthetsera potenthetsa, komanso ngati sinki kuti akane mphamvu mukamazizira. Mitundu ya machitidwewa ili ndi zigawo ziwiri zazikulu:
- Ground Heat Exchanger: Ichi ndi chotenthetsera chomwe chimagwiritsidwa ntchito kuwonjezera kapena kuchotsa mphamvu zotentha padziko lapansi kapena pansi. Zosintha zosiyanasiyana zosinthira kutentha zimatha, ndipo zafotokozedwa pambuyo pake m'gawoli.
- Pampu Yotentha: M'malo mwa mpweya, mapampu otentha apansi amagwiritsira ntchito madzi oyenda pansi pa kutentha kwapansi monga gwero lawo (potentha) kapena kuzama (pozizira).
Kumbali yomanga, machitidwe onse a mpweya ndi hydronic (madzi) ndizotheka. Kutentha kogwira ntchito kumbali yomanga ndikofunika kwambiri pakugwiritsa ntchito hydronic. Mapampu otenthetsera amagwira ntchito bwino kwambiri akatenthetsa kutentha kochepera pansi pa 45 mpaka 50 ° C, zomwe zimapangitsa kuti zigwirizane bwino ndi pansi powala kapena makina amakoyilo a fan. Chisamaliro chiyenera kutengedwa ngati kuganizira kugwiritsa ntchito kwawo ndi ma radiator otentha omwe amafunikira kutentha kwa madzi pamwamba pa 60 ° C, chifukwa kutentha kumeneku kumadutsa malire a mapampu ambiri otentha omwe amakhalamo.
Kutengera momwe pampu yotenthetsera ndi kutentha kwapansi zimalumikizirana, magawo awiri amitundu yosiyanasiyana ndizotheka:
- Sekondale Loop: Madzi (madzi apansi kapena anti-freeze) amagwiritsidwa ntchito posinthanitsa kutentha kwapansi. Mphamvu yotentha yomwe imasamutsidwa kuchokera pansi kupita kumadzimadzi imaperekedwa ku mpope wa kutentha kudzera pa chotenthetsera kutentha.
- Kukula Mwachindunji (DX): Refrigerant imagwiritsidwa ntchito ngati madzi mu chowotcha chapansi. Mphamvu yotentha yomwe imatulutsidwa ndi firiji kuchokera pansi imagwiritsidwa ntchito mwachindunji ndi mpope wa kutentha - palibe chowonjezera chowonjezera chotentha chomwe chimafunika.
M'machitidwe awa, chowotchera kutentha pansi ndi gawo la mpope wotentha womwewo, womwe umakhala ngati evaporator mu Kutentha mode ndi condenser mu kuzizira mode.
Mapampu otentha apansi panthaka amatha kukhala ndi zosowa zapanyumba panu, kuphatikiza:
- Kutentha kokha: Pampu yotentha imagwiritsidwa ntchito potenthetsa. Izi zitha kuphatikizira kutenthetsa malo komanso kupanga madzi otentha.
- Kutentha ndi "kuzizira kogwira": Pampu yotentha imagwiritsidwa ntchito potentha ndi kuziziritsa
- Kutenthetsa ndi "kuzizira kopanda": Pampu yotentha imagwiritsidwa ntchito potenthetsa, ndipo imadutsa pozizira. Mu kuzirala, madzimadzi kuchokera m'nyumba utakhazikika mwachindunji pansi kutentha exchanger.
Kutentha ndi "kuzizira kogwira ntchito" akufotokozedwa mu gawo lotsatirali.
Ubwino Waukulu wa Pampu Pampu Yochokera Pansi
Kuchita bwino
Ku Canada, komwe kutentha kwa mpweya kumatha kutsika pansi -30 ° C, makina oyambira pansi amatha kugwira ntchito bwino chifukwa amapezerapo mwayi wotentha komanso wokhazikika. Kutentha kwamadzi komwe kumalowera pampopu yochokera pansi pamadzi nthawi zambiri kumakhala kopitilira 0 ° C, kumapereka COP yozungulira 3 pamakina ambiri m'miyezi yozizira kwambiri.
Kupulumutsa Mphamvu
Makina oyambira pansi achepetsa mtengo wanu wotenthetsera ndi kuziziritsa kwambiri. Kuwotcha mphamvu zopulumutsa mphamvu poyerekeza ndi ng'anjo magetsi ndi mozungulira 65%.
Pa avareji, makina opangira gwero lopangidwa bwino adzapereka ndalama zomwe zimakhala pafupifupi 10-20% kuposa zomwe zingapatsidwe ndi apamwamba kwambiri mkalasi, pompa yotentha yochokera kumphepo yoziziritsa yotentha yokulirapo kuti itseke zambiri zotenthetsera nyumbayo. Izi ndichifukwa choti kutentha kwapansi panthaka kumakhala kokwera kwambiri m'nyengo yozizira kuposa kutentha kwa mpweya. Chotsatira chake, pampu yotentha yochokera pansi imatha kupereka kutentha kwambiri m'nyengo yozizira kusiyana ndi mpweya wotentha wa mpweya.
Kupulumutsa mphamvu zenizeni kudzasiyana malinga ndi nyengo ya m'deralo, mphamvu ya makina otenthetsera omwe alipo, mtengo wamafuta ndi magetsi, kukula kwa pampu yotenthetsera yomwe yaikidwa, kamangidwe ka borefield ndi mphamvu yamagetsi a nyengo, komanso kagwiritsidwe ntchito ka pampu yotentha ku CSA. mikhalidwe mlingo.
Kodi Ground-Source System Imagwira Ntchito Motani?
Mapampu otentha apansi panthaka amakhala ndi magawo awiri akulu: Chosinthira kutentha pansi, ndi pampu yotenthetsera. Mosiyana ndi mapampu otentha opangira mpweya, komwe chowotcha chimodzi chimakhala panja, m'makina oyambira pansi, pampu yotentha imakhala mkati mwa nyumba.
Mapangidwe a kutentha kwapansi atha kugawidwa motere:
- Lupu Lotsekeka: Makina otsekeka amatenga kutentha kuchokera pansi pogwiritsa ntchito mipope yotsekera pansi. Njira ya antifreeze (kapena refrigerant ngati DX ground-source system), yomwe yatenthedwa ndi firiji ya pampu yotentha mpaka madigiri angapo kuzizira kuposa nthaka yakunja, imazungulira papaipi ndikuyamwa kutentha kwa nthaka.
Mipope yodziwika bwino pamakina otsekeka amaphatikiza zopingasa, zoyima, zozungulira ndi ma dziwe/nyanja (makonzedwe awa akukambidwa pansipa, pansi pa Zolinga Zopangira). - Tsegulani Loop: Tsegulani makina amapezerapo mwayi pakutentha komwe kumasungidwa m'madzi apansi panthaka. Madziwo amatungidwa m’chitsime molunjika kumalo otenthetsera kutentha, kumene kutentha kwake kumachokera. Madziwo amachotsedwa kumadzi a pamwamba pa nthaka, monga mtsinje kapena dziwe, kapena kubwereranso kumadzi omwewo apansi pa nthaka kudzera pachitsime china.
Kusankhidwa kwa mapaipi akunja kumadalira nyengo, malo a nthaka, malo omwe alipo, ndalama zoyikapo malo pamalopo komanso malamulo a municipalities ndi chigawo. Mwachitsanzo, makina otsegula amaloledwa ku Ontario, koma saloledwa ku Quebec. Ma municipalities ena aletsa machitidwe a DX chifukwa gwero lamadzi la municipalities ndilo aquifer.
Kutentha Kuzungulira
Ndemanga:
Zina mwazolemba zatengedwa pa intaneti. Ngati pali kuphwanya kulikonse, chonde titumizireni kuti tichotse. Ngati mumakonda zinthu zopopera kutentha, chonde omasuka kulumikizana ndi kampani yapompopi yotentha ya OSB, ndife chisankho chanu chabwino.
