Kuchepetsa kagwiritsidwe ntchito ka mphamvu pamakina otenthetsera, mpweya wabwino ndi mpweya (HVAC) kwakhala kofunika kwambiri chifukwa cha kukwera mtengo kwamafuta oyambira pansi komanso zovuta zachilengedwe.Chifukwa chake, kupeza njira zatsopano zochepetsera kugwiritsa ntchito mphamvu m'nyumba popanda kusokoneza chitonthozo komanso mpweya wabwino wamkati ndivuto lofufuza lomwe likupitilira.Njira imodzi yotsimikiziridwa yokwaniritsira mphamvu zamagetsi m'makina a HVAC ndikupanga makina omwe amagwiritsa ntchito masanjidwe atsopano azinthu zomwe zilipo kale.Chilango chilichonse cha HVAC chimakhala ndi zofunikira zamapangidwe ake ndipo chilichonse chimapereka mwayi wopulumutsa mphamvu.Makina a HVAC osagwiritsa ntchito mphamvu amatha kupangidwa pokonzanso machitidwe azikhalidwe kuti agwiritse ntchito mwanzeru magawo omwe alipo.Kafukufuku waposachedwapa wasonyeza kuti kuphatikiza kwa matekinoloje omwe alipo kale angapereke njira zothetsera mphamvu zotetezera mphamvu ndi kutonthoza kutentha.Pepalali likufufuza ndikuwunikanso matekinoloje ndi njira zosiyanasiyana, ndikuwonetsa kuthekera kwawo pakuwongolera magwiridwe antchito a machitidwe a HVAC kuti achepetse kugwiritsa ntchito mphamvu.Panjira iliyonse, kufotokozera mwachidule kumaperekedwa koyamba kenako ndikuwunikanso maphunziro am'mbuyomu, kukopa kwa njirayo pakupulumutsa mphamvu kwa HVAC kumafufuzidwa.Pomaliza, kafukufuku woyerekeza pakati pa njirazi amachitika.
Miyezo ya ASHRAE imalimbikitsa kuchuluka kwa mpweya wabwino wofunikira panyumba zosiyanasiyana.Mpweya wopanda mpweya umapangitsa kuti nyumbayo ikhale yozizirira bwino, zomwe zimapangitsa kuti magetsi azigwiritsidwa ntchito m'nyumba zonse za HVAC.Pakatikati pa chozizira chozizira, kuchuluka kwa mpweya wabwino kumatsimikiziridwa kutengera malire apamwamba a zowononga mpweya wamkati zomwe nthawi zambiri zimakhala pakati pa 10% ndi 30% ya kuchuluka kwa mpweya wotuluka [69].M'nyumba zamakono kutayika kwa mpweya wabwino kumatha kukhala oposa 50% ya kutaya kwathunthu kwamafuta [70].Komabe, mpweya wabwino wamakina ukhoza kuwononga mpaka 50% ya mphamvu zamagetsi zomwe zimagwiritsidwa ntchito mnyumba zogona [71].Kuonjezera apo, m'madera otentha ndi amvula makina opangira mpweya wabwino ndi oyenera pafupifupi 20-40% ya mphamvu zonse zomwe zimagwiritsidwa ntchito pamagetsi [72].Nasif et al.[75] adaphunzira kugwiritsa ntchito mphamvu pachaka kwa choyatsira mpweya pamodzi ndi enthalpy/membrane heat exchanger ndikufanizira ndi mpweya wokhazikika.Iwo adapeza kuti m'nyengo yachinyontho, kupulumutsa mphamvu pachaka mpaka 8% kumatheka mukamagwiritsa ntchito chojambulira kutentha kwa nembanemba m'malo mwa njira wamba ya HVAC.
Holtop okwana kutentha exchangeramapangidwa ndi pepala la ER lomwe limawoneka ndi kutha kwa chinyezi chambiri, kulimba kwa mpweya wabwino, kukana misozi, komanso kukana kukalamba.Chilolezo pakati pa ulusi ndi chochepa kwambiri, kotero kuti mamolekyu a chinyezi ang'onoang'ono ang'onoang'ono amatha kudutsamo, mamolekyu onunkhira omwe ali ndi mainchesi akuluakulu sangathe kudutsamo.Mwanjira imeneyi, kutentha ndi chinyezi zimatha kubwezeretsedwa bwino, ndikuletsa zowononga kulowa mumpweya wabwino.
6.Zotsatira zamakhalidwe omanga
Kugwiritsa ntchito mphamvu kwa dongosolo la HVAC sikungotengera momwe amagwirira ntchito komanso momwe amagwirira ntchito, komanso mawonekedwe a kutentha ndi kuzizira komanso momwe nyumbayo imagwirira ntchito.Katundu weniweni wamakina a HVAC ndi wocheperako kuposa momwe amapangidwira nthawi zambiri zogwirira ntchito chifukwa cha machitidwe omanga.Chifukwa chake, zinthu zofunika kwambiri zomwe zimathandizira kuchepetsa kugwiritsa ntchito mphamvu kwa HVAC mnyumba yoperekedwa ndikuwongolera koyenera kwa kutentha ndi kuziziritsa.Kuwongolera kophatikizika kwa zida zoziziritsa zomangira, monga cheza chadzuwa, kuyatsa ndi mpweya wabwino, zitha kupulumutsa mphamvu zambiri panyumba yozizirira yanyumba.Akuti pafupifupi 70% ya ndalama zopulumutsira mphamvu ndizotheka pogwiritsa ntchito matekinoloje abwinoko kuti agwirizane ndi kufunikira kwa nyumbayo ndi mphamvu yake ya HVAC.Korolija et al.adafufuza za ubale womwe ulipo pakati pa kumanga kutentha ndi katundu woziziritsa komanso kugwiritsa ntchito mphamvu kotsatira ndi makina osiyanasiyana a HVAC.Zotsatira zawo zidawonetsa kuti mphamvu yomanga nyumbayo singawunikidwe pongotengera kutentha kwanyumba ndi kuzizira chifukwa chodalira mawonekedwe amafuta a HVAC.Huang etal.adapanga ndikuwunika ntchito zisanu zowongolera mphamvu zoyendetsedwa molingana ndi momwe zimakhalira ndikugwiritsiridwa ntchito kwa makina osinthika amtundu wa HVAC.Zotsatira zawo zofananira zikuwonetsa kuti kupulumutsa mphamvu kwa 17% kumatha kukwaniritsidwa pamene dongosololi likugwiritsidwa ntchito ndi ntchito zowongolera izi.
Machitidwe ochiritsira a HVAC amadalira kwambiri mphamvu yopangidwa kuchokera ku mafuta oyaka, omwe akutha mofulumira.Izi limodzi ndi kufunikira kokulirapo kwa zomangamanga ndi zida zamagetsi zotsika mtengo zapangitsa kuti kukhazikitsidwe kwatsopano ndi kukonzanso kwakukulu m'nyumba zomwe anthu akukhalamo kuti akwaniritse mphamvu zamagetsi komanso kukhazikika kwa chilengedwe.Chifukwa chake, kupeza njira zatsopano zopangira nyumba zobiriwira popanda kusokoneza chitonthozo komanso mpweya wamkati wamkati kumakhalabe vuto pakufufuza ndi chitukuko.Kuchepetsa komwe kungatheke kwa kugwiritsa ntchito mphamvu ndi kupititsa patsogolo chitonthozo cha anthu mnyumbazo kumadalira momwe machitidwe a HVAC amagwirira ntchito.Njira imodzi yotsimikiziridwa yokwaniritsira mphamvu zamagetsi m'makina a HVAC ndikupanga makina omwe amagwiritsa ntchito masanjidwe atsopano azinthu zomwe zilipo kale.Kafukufuku waposachedwapa wasonyeza kuti kuphatikizika kwa matekinoloje omwe alipo kale atha kupereka njira zothetsera mphamvu zowonongolera mphamvu komanso kutonthoza matenthedwe.Mu pepalali njira zosiyanasiyana zopulumutsira mphamvu zamakina a HVAC zidafufuzidwa ndipo kuthekera kwawo kopititsa patsogolo magwiridwe antchito amakambidwe.Zinapezeka kuti zinthu zingapo monga nyengo, kuyembekezera chitonthozo matenthedwe, koyamba ndi likulu mtengo, kupezeka kwa magwero mphamvu ndi ntchito.
