Mavavu wamba mu dongosolo air conditioning madzi mavavu wamba mu mpweya mpweya dongosolo madzi ndi valavu butterfly, valavu valavu, valavu globe, valavu mpira, etc., ntchito yeniyeni imene valavu, tiyenera choyamba kumvetsa chapakati mpweya dongosolo madzi. Dongosolo lamadzi lapakati pa air conditioning system limaphatikizapo madzi ozizira ndi madzi ozizira / madzi otentha (nthawi zambiri chitoliro chimodzi, kuyendayenda madzi oundana m'chilimwe ndi madzi otentha m'nyengo yozizira). Mpweya woziziritsidwa kapena mpweya wozizidwa ndi mtundu wa pampu wotenthetsera umaphatikizapo firiji/madzi otentha okha.
Air conditioning madzi mavavu ambiri ntchito valavu gulugufe, valavu cheke, valavu globe, valavu mpira, etc., ntchito yeniyeni imene valavu, tiyenera choyamba kumvetsa chapakati mpweya mpweya dongosolo madzi.
Dongosolo lamadzi lapakati pa air conditioning system limaphatikizapo madzi ozizira ndi madzi ozizira / madzi otentha (nthawi zambiri chitoliro chimodzi, kuyendayenda madzi oundana m'chilimwe ndi madzi otentha m'nyengo yozizira). Mpweya woziziritsidwa kapena mpweya wozizidwa ndi mtundu wa pampu wotenthetsera umaphatikizapo firiji/madzi otentha okha. Dongosolo la madzi ozungulira ndi gawo lofunikira kwambiri pakatikati pa air conditioning system.
Chigawo chapakati chowongolera mpweya chimakhala ndi magawo atatu: makina ozungulira madzi ozizira, makina ozungulira madzi ozizira ndi injini yayikulu:
Chilled madzi kufalitsidwa dongosolo
Gawoli limapangidwa ndi chilled pampu, fan yamkati ndi chitoliro chamadzi ozizira. Madzi ozizira otentha otsika kuchokera ku evaporator ya makina ochitira alendo amakanikizidwa mu chitoliro cha madzi ozizira (madzi otulutsira madzi) ndi mpope wa refrigerant, amalowa m'chipinda chosinthira kutentha, amachotsa kutentha m'chipindacho, ndikubwerera ku evaporator. makina osungira (madzi obwerera). Chokupizira chamkati chimagwiritsidwa ntchito powomba mpweya kudzera papaipi yamadzi ozizira kuti muchepetse kutentha kwa mpweya ndikufulumizitsa kusinthana kwa kutentha kwamkati.
Kuzizira madzi kufalitsidwa gawo
Mbali imeneyi wapangidwa ndi kuzirala mpope, kuzirala chitoliro madzi, yozizira nsanja madzi, etc. Chilled madzi kufalitsidwa dongosolo m'nyumba kutentha kuwombola pa nthawi yomweyo, adzachotsa zambiri m'nyumba kutentha. Mphamvu ya kutentha imasamutsidwa kumadzi ozizira kudzera mufiriji mu injini yaikulu, kotero kuti kutentha kwa madzi ozizira kumakwera. Pampu yozizira idzatenthetsa madzi ozizira ozizira mu nsanja yamadzi ozizira (madzi), kuti athe kusinthanitsa kutentha ndi mlengalenga, kuchepetsa kutentha ndikubwereranso ku injini yaikulu ya condenser (kubwezeretsa madzi).
Olandila alendo
Injini yayikulu imapangidwa ndi kompresa, evaporator, condenser ndi refrigerant (firiji). Njira yake yogwirira ntchito ndi motere:
Choyamba, refrigerant yotsika kwambiri ya gaseous imapanikizidwa ndi kompresa mu condenser ndipo pang'onopang'ono imasinthidwa kukhala madzi othamanga kwambiri. Panthawi ya condensation, refrigerant imamasula mphamvu zambiri zotentha, zomwe zimatengedwa ndi madzi ozizira mu condenser ndikutumiza ku nsanja yoziziritsa kunja, ndipo potsirizira pake imatulutsidwa mumlengalenga. Ndiye pamene mkulu kuthamanga madzi refrigerant mu condenser umayenda mwa throttling ndi sitepe-pansi chipangizo pamaso evaporator, ndi vaporized chifukwa cha mwadzidzidzi kusintha kuthamanga, kupanga mpweya wamadzi osakaniza ndi kulowa evaporator. Refrigerant imatenthedwa nthawi zonse mu evaporator, ndipo imayamwa kutentha kwa madzi owundana kuti madzi oundanawo afike potsika kutentha. ***, refrigerant mu evaporator pambuyo gasification amakhala otsika-anzanu mpweya, amalowanso kompresa, ndi zina zotero.
Valavu yowongolera yomwe imagwiritsidwa ntchito m'madzi owongolera mpweya imadziwikanso kuti valavu yowongolera, ili m'mapaipi kuti isinthe chida chowongolera madzi kapena gasi. Kusintha kumeneku kumatheka mwa kusintha kutsegulidwa kwa ma valve olamulira omwe amagwirizanitsidwa mndandanda ku dongosolo la mapaipi, motero kusintha kukana kwamadzimadzi.
Kusankhidwa kwa valavu yolamulira ndikofunika kwambiri kupititsa patsogolo kukhazikika kwa dongosolo, kutalikitsa moyo wautumiki wa valve yolamulira ndikupulumutsa mphamvu. Popanda valavu yoyenera, njira yoyendetsera madzi yomwe imayendetsedwa yokha sichigwira ntchito bwino. Kuchulukirachulukira kwa valavu kungayambitse kuwongolera koyipa, kungapangitse dongosolo kugwedezeka kapena kugwedezeka, ndikuwononga ndalama; Pang'onopang'ono valavu ya valve idzafuna kuti dongosololi lipereke kusiyana kwakukulu kwapakati kuti pakhale kuyenda kokwanira, kuti pampu yolemetsa ikhale yolemetsa, pamene valavu ili pangozi yowonongeka, ndipo sangapereke mphamvu yofunikira; Zonsezi zidzabweretsa kusokoneza kukonza ndikufupikitsa moyo wautumiki wa valve yolamulira.
Kuchokera kuzomwe zili pamwambazi, tinganene kuti ma valve omwe amagwiritsidwa ntchito kwambiri pamadzi oyendetsa mpweya ndi awa: valavu ya butterfly, valavu ya butterfly yamagetsi, anti-condensation butterfly valve, butterfly check valve, valve control valve, valve yodula, etc. Komanso ayenera mphira zofewa kugwirizana, fyuluta ndi Chalk zina chitoliro.
