Ku Australia, ma HPWHs amapanga pafupifupi 3 peresenti ya zotenthetsera madzi zomwe zimagwiritsidwa ntchito. Pa nthawi ya malonda a 2012 panali pafupifupi mitundu 18 ndi mitundu pafupifupi 80 ya HPWH pamsika ku Australia, ndi mitundu 9 ndi mitundu 25 ku New Zealand.
Kodi Heat Pump Water Heater ndi chiyani?
Pampu yamadzi yotenthetsera imatenga kutentha kuchokera mumlengalenga ndikusamutsira kumadzi otentha. Chifukwa chake amatchedwanso 'air-source heat pump'. Amagwiritsa ntchito magetsi koma amagwira ntchito bwino kuwirikiza katatu kuposa chotenthetsera madzi wamba. Akagwiritsidwa ntchito pamalo abwino amapulumutsa mphamvu, amasunga ndalama komanso amachepetsa mpweya wowonjezera kutentha.
Zimagwira ntchito bwanji?
Pampu yotentha imagwira ntchito mofanana ndi firiji, koma m'malo motulutsa kutentha mu furiji kuti ikhale yozizira, imatulutsa kutentha m'madzi. Magetsi amagwiritsidwa ntchito kupopera firiji kudzera mu dongosolo. Refrigerant imasamutsa kutentha komwe kumachokera mumlengalenga kupita kumadzi mu thanki.
Chithunzi 1. Ntchito za mpope wa kutentha
Chithunzi chofotokozera momwe chotenthetsera madzi chimagwirira ntchito.
Mapampu otentha amagwira ntchito pogwiritsa ntchito firiji yomwe imatuluka nthunzi pa kutentha kochepa.
Pali njira zingapo pochita izi:
Refrigerant yamadzimadzi imadutsa mu evaporator komwe imanyamula kutentha kuchokera mumlengalenga ndikukhala mpweya.
Refrigerant ya gasi imapanikizidwa mu kompresa yamagetsi. Kupondereza gasi kumapangitsa kutentha kwake kuti kukhale kotentha kuposa madzi a mu thanki.
Mpweya wotenthawo umalowa mu condenser, mmene umapititsira kutentha kwake kumadzi ndi kubwereranso kukhala madzi.
Refrigerant yamadzimadzi imathamangira mu valavu yowonjezera kumene kuthamanga kwake kumachepetsedwa, kulola kuti kuziziritsa ndi kulowa mu evaporator kubwereza kuzungulira.
Pampu yotentha imagwiritsa ntchito magetsi kuyendetsa kompresa ndi fani m'malo mwake, mosiyana ndi chotenthetsera chamadzi chomwe chimagwiritsa ntchito magetsi kutenthetsa madzi mwachindunji. Pampu yotentha imatha kusamutsa mphamvu zambiri zotentha kuchokera ku mpweya wozungulira kupita kumadzi, zomwe zimapangitsa kuti zikhale zogwira mtima kwambiri. Kuchuluka kwa kutentha komwe kumatha kusamutsidwa kuchokera kumlengalenga kupita kumadzi kumadalira kutentha komwe kulipo.
Ngakhale kutentha kwakunja kumakhala kokwera kuposa firiji yozizira, pampu yotentha imatenga kutentha ndikusunthira kumadzi. Kutentha kwakunja kwa mpweya, kumakhala kosavuta kuti pampu yotentha ipereke madzi otentha. Kutentha kwakunja kumachepa, kutentha kochepa kumatha kusamutsidwa, chifukwa chake mapampu otentha samagwiranso ntchito m'malo omwe kutentha kumakhala kotsika.
Kuti evaporator ilole kutentha kulowetsedwa mosalekeza, pamafunika kukhala ndi mpweya wabwino nthawi zonse. Chofanizira chimagwiritsidwa ntchito kuthandizira kutuluka kwa mpweya ndikuchotsa mpweya wozizira.
Mapampu otentha amapezeka m'makonzedwe awiri; machitidwe ophatikizika / ophatikizika, ndi machitidwe ogawa.
Machitidwe ophatikizika / ophatikizika: kompresa ndi tanki yosungira ndi gawo limodzi.
Makina ogawanitsa: thanki ndi kompresa ndizosiyana, ngati chowongolera mpweya.
