Mapampu Otentha Ochokera ku Air-Source mu Nyengo Yozizira

Cholepheretsa chachikulu cha mapampu otentha a mpweya ndi kuchepa kwakukulu kwa magwiridwe antchito pomwe kutentha kwakunja kumafika kuzizira.

Mapampu otentha akutuluka ngati njira yabwino yothetsera kutentha kwa malo ndi mpweya, makamaka akagwiritsidwa ntchito m'makina oyendera mafiriji. Angathe kufanana ndi machitidwe abwino kwambiri a mpweya wozizira mumayendedwe ozizira, ndipo amatha kupikisana ndi mtengo wotsika wa kutentha kwa moto pamene akugwiritsa ntchito magetsi okha. Poyerekeza ndi chotenthetsera chokhazikika chokana, pampu yotenthetsera imakwaniritsa kusungidwa kwapakati pa 40 mpaka 80 peresenti, malingana ndi chitsanzo chapadera ndi zochitika zogwirira ntchito.

Ngakhale mapampu otentha a mpweya amasinthanitsa kutentha mwachindunji ndi mpweya wakunja, mapampu otentha apansi amatenga mwayi pa kutentha kwapansi pansi kuti akwaniritse bwino kwambiri. Poganizira za mtengo wapamwamba ndi kuyika zovuta za dongosolo lochokera pansi, mapampu otentha a mpweya ndi njira yofala kwambiri.

Cholepheretsa chachikulu cha mapampu otentha a mpweya ndi kuchepa kwakukulu kwa magwiridwe antchito pomwe kutentha kwakunja kumafika kuzizira. Akatswiri opanga mapulani amayenera kuganizira momwe nyengo ikugwirira ntchito pofotokoza pampu ya kutentha, ndikuwonetsetsa kuti makinawo ali ndi njira zokwanira zoyezera kutentha komwe kumayembekezeredwa.

Kodi Kuzizira Kwambiri Kumakhudza Bwanji Mapampu Otentha a Air-Source?

Chovuta chachikulu mukamagwiritsa ntchito pampu yotenthetsera yochokera ku mpweya yokhala ndi kuzizira kozizira ndikuwongolera kuchulukana kwa ayezi pamakoyilo akunja. Popeza chipangizocho chikuchotsa kutentha kwa mpweya wakunja womwe ukuzizira kale, chinyezi chimatha kusonkhanitsa mosavuta ndikuundana pamwamba pa makola ake.

Ngakhale kutentha kwa pampu yotentha kumatha kusungunula ayezi pamakoyilo akunja, gawoli silingathe kutulutsa kutentha kwa danga pomwe kuzungulira kumatenga. Kutentha kwakunja kumatsika, pampu yotentha iyenera kulowa munyengo ya defrost pafupipafupi kuti ibwezere kupanga ayezi, ndipo izi zimachepetsa kutentha komwe kumaperekedwa m'malo amkati.

Popeza mapampu otentha ochokera pansi sasinthanitsa kutentha ndi mpweya wakunja, samakhudzidwa ndi kuzizira. Komabe, amafuna kukumba zomwe zingakhale zovuta kuzichita pansi pa nyumba zomwe zilipo kale, makamaka zomwe zili m'matauni omwe ali ndi anthu ambiri.

Kutchula Mapampu Otentha a Air-Source a Nyengo Yozizira

Mukamagwiritsa ntchito mapampu otentha opangidwa ndi mpweya okhala ndi kuzizira kozizira, pali njira ziwiri zazikulu zolipirira kutayika kwa kutentha panthawi ya defrost:

Kuwonjezera chowotchera chosungirako, nthawi zambiri choyatsira gasi kapena chowotcha chamagetsi.
Kutchula pampu yotenthetsera yokhala ndi miyeso yomangidwira motsutsana ndi kuchuluka kwa chisanu.
Zosungirako zosungirako zotenthetsera mapampu opangira mpweya ndi njira yosavuta, koma zimakonda kuonjezera mtengo wa umwini. Zolinga zamapangidwe zimasintha kutengera mtundu wa zotenthetsera zosungira zomwe zatchulidwa:

Chowotcha chamagetsi chamagetsi chimayenda ndi gwero lamphamvu lofanana ndi pampu yotentha. Komabe, imakoka kwambiri pamoto wotenthetsera womwe wapatsidwa, womwe umafuna kuti mawaya achuluke. Kugwira ntchito kwadongosolo lonse kumatsikanso, chifukwa kutenthetsa kukana sikuthandiza kwambiri kuposa ntchito yopopera kutentha.
Chowotcha gasi chimapeza mtengo wotsika kwambiri kuposa chotenthetsera. Komabe, pamafunika kuperekera gasi ndi makina otulutsa mpweya, kuthamangitsa mtengo wa kukhazikitsa.
Makina opopera kutentha akamagwiritsa ntchito kutentha kosungirako, mchitidwe wovomerezeka ndikuyika chotenthetsera pa kutentha pang'ono. Izi zimachepetsa mafupipafupi a kuzungulira kwa defrost ndi nthawi yogwiritsira ntchito makina otenthetsera osunga zobwezeretsera, kutsitsa kugwiritsa ntchito mphamvu zonse.

Mapampu Otentha Okhala Ndi Njira Zomangidwira Polimbana ndi Kuzizira

Mapampu otenthetsera mpweya wochokera kwa opanga otsogola nthawi zambiri amavotera kutentha kwakunja mpaka -4°F. Komabe, mayunitsi akawongoleredwa ndi njira zoziziritsira nyengo yozizira, magwiridwe antchito ake amatha kupitilira -10 ° F kapena ngakhale -20 ° F. Zotsatirazi ndi zina mwamapangidwe omwe amagwiritsidwa ntchito ndi opanga mapampu otentha kuti achepetse kukhudzidwa kwa kuzungulira kwa defrost:

Opanga ena amaphatikiza ma accumulators a kutentha, omwe amatha kupitiliza kutulutsa kutentha pamene pampu yotentha imalowa m'nyengo ya defrost.
Palinso masanjidwe a pampu ya kutentha komwe mizere yotentha ya refrigerant imazungulira panja kuti iteteze kuzizira. Kuzungulira kwa defrost kumangoyambitsa pamene kutentha kumeneku sikukwanira.
Makina opopera kutentha akamagwiritsa ntchito mayunitsi angapo akunja, amatha kukonzedwa kuti alowe mumayendedwe a defrost motsatizana osati nthawi imodzi. Mwanjira iyi, dongosololi silitaya mphamvu yake yonse yotentha chifukwa cha defrosting.
Magawo akunja amathanso kukhala ndi nyumba zomwe zimateteza chipangizocho ku chipale chofewa. Mwanjira iyi, gawoli liyenera kuthana ndi ayezi omwe amapanga molunjika pamakoyilo.
Ngakhale kuti njirazi sizimathetsa kuzungulira kwa defrost kwathunthu, zimatha kuchepetsa zotsatira zake pakuwotcha. Kuti mukwaniritse zotsatira zabwino kwambiri ndi makina opopera kutentha kwa mpweya, chinthu choyamba choyenera ndikuwunika momwe nyengo ikuyendera. Mwanjira iyi, dongosolo lokwanira likhoza kufotokozedwa kuyambira pachiyambi; chomwe chiri chosavuta komanso chotsika mtengo chomwe chikukweza kuyika kosayenera.

Njira Zowonjezera Kupititsa patsogolo Kugwira Ntchito Pampu Kutentha

Kukhala ndi pampu yotenthetsera yopatsa mphamvu kumachepetsa ndalama zotenthetsera ndi kuziziziritsa. Komabe, nyumbayo yokhayo imatha kupangidwanso kuti ichepetse kuzizirira nthawi yachilimwe komanso kutentha kwanyengo yozizira. Envulopu yanyumba yokhala ndi zotchingira zotchingira bwino komanso zotchingira mpweya imachepetsa kufunika kotenthetsa ndi kuziziritsa, poyerekeza ndi nyumba yosatsekeredwa bwino komanso kutulutsa mpweya wambiri.

Kuwongolera mpweya kumathandizanso kutenthetsa ndi kuzizira bwino, posintha kayendedwe ka mpweya malinga ndi zosowa za nyumbayo. Pamene mpweya wabwino umagwira ntchito nthawi zonse, mpweya umene umayenera kukhala wokhazikika umakhala wapamwamba. Kumbali ina, ngati mpweya wa mpweya usinthidwa malinga ndi momwe mumakhala, mpweya wonse womwe umayenera kukhala wokhazikika umakhala wotsika.

Pali mitundu yosiyanasiyana ya kutentha ndi kuzizira komwe kungathe kutumizidwa m'nyumba. Komabe, mtengo wotsikitsitsa wa umwini umatheka pamene kuyikako kumakonzedwa molingana ndi zosowa za nyumbayo.

Ngati mukufuna kukhala ndi vuto lopanda vuto ndi vuto lotsika pakutentha kocheperako kwa zinthu zopopera kutentha, tingakhale okondwa kukudziwitsani mapampu athu otentha a EVI! M'malo mwa kutentha kwapakati -7 mpaka 43 ° C, amatha kuthamanga kwambiri mpaka -25 digiri Celsius. Khalani omasuka kulankhula nafe kuti mudziwe zambiri!
