Geothermal vs. Air-Source Kutentha Pampu

Njira yopulumutsira mphamvu ya ng'anjo yamoto yoyaka moto, pampu yotentha ndi yabwino kwa eni nyumba omwe ali ndi bajeti, wosamalira zachilengedwe. Koma kodi muyenera kusankha pampu yotenthetsera yotsika mtengo kapena kuyika ndalama mu geothermal system?

Momwe Mapampu Otentha Amagwirira Ntchito

Pampu yotentha imagwira ntchito mosiyana kwambiri ndi ng'anjo yachikhalidwe. M'malo mowotcha mafuta kuti apangitse kutentha, pampu yotenthetsera imangosuntha kutentha kuchokera pamalo amodzi ("gwero") kupita kumalo ena. Mapampu otenthetsera mpweya amasonkhanitsa ndi kusamutsa kutentha kuchokera mumlengalenga pomwe mapampu otentha a geothermal amasonkhanitsa ndikusamutsa kutentha kuchokera pansi. Mitundu yonse iwiri ya mapampu otentha amathanso kugwira ntchito ngati njira zozizirira m'chilimwe, kusamutsa kutentha kuchokera mkati kupita kunja. Poyerekeza ndi ng'anjo zakale ndi zoziziritsira mpweya, mapampu otentha amafunikira mphamvu zochepa kuti agwire ntchito ndikuchepetsa kwambiri mpweya woipa.

Geothermal vs. Air-Source Kutentha Pampu

Pankhani yogwira ntchito bwino, mapampu otentha a geothermal ndi apamwamba kwambiri kuposa magwero a mpweya. Izi zili choncho chifukwa kutentha kwa pansi pa nthaka kumakhala kokhazikika poyerekeza ndi kutentha kwa mpweya pamwamba pa nthaka. Mwachitsanzo, kutentha kwapansi pa kuya kwa 10 mapazi kumatha kukhala pafupifupi madigiri 50 Fahrenheit nyengo yonse yachisanu. Pa kutentha uku, pampu yotentha imagwira ntchito bwino kwambiri. M'malo mwake, mkati mwa kutentha koyenera, mapampu otenthetsera abwino kwambiri a mpweya amatha kugwira ntchito pafupifupi 250 peresenti. Izi zikutanthauza kuti pa $ 1 iliyonse yomwe mumagwiritsa ntchito magetsi, mumalandira $ 2.50 ya kutentha. Komabe, kutentha pamwamba pa nthaka kukatsika pansi pafupifupi madigiri 42, mapampu otentha a mpweya amayamba kugwira ntchito bwino. Ayezi adzayamba kupanga panja, ndipo pampu yotentha imayenera kulowa mumsewu wosakwanira wa defrost pafupipafupi kuti ulipire. Chifukwa pampu ya kutentha kwa geothermal imatulutsa kutentha kuchokera ku gwero ndi kutentha kosasinthasintha, ikugwira ntchito mosalekeza pamlingo wake wothandiza kwambiri - pafupifupi 500 peresenti yogwira ntchito bwino. N'chimodzimodzinso m'chilimwe pamene kutentha kwa nthaka nthawi zambiri kumakhala pakati pa 60 ndi 70 madigiri. Ngakhale pampu yotentha yochokera ku mpweya imatha kugwira ntchito ngati njira yozizirira bwino pa kutentha pang'ono, imakhala yochepa kwambiri kutentha kumakwera, kunena kuti, madigiri 90 kapena kupitilira apo. Malinga ndi EPA, makina otenthetsera ndi kuziziritsa a geothermal amatha kuchepetsa kugwiritsa ntchito mphamvu ndi mpweya wofanana ndi 40 peresenti poyerekeza ndi pampu yotentha yochokera ku mpweya, komanso kupitilira 70 peresenti poyerekeza ndi zida zotenthetsera ndi zoziziritsa.
