Kodi condenser imagwira ntchito bwanji?

Chotenthetsera mpweya chimagwira ntchito podutsa mpweya kudzera mu chubu chachitali (nthawi zambiri chimakulungidwa mu solenoid), zomwe zimathandiza kuti kutentha kutayike mumlengalenga wozungulira. Zitsulo monga mkuwa zimakhala ndi mphamvu yotenthetsera kutentha kwambiri ndipo nthawi zambiri zimagwiritsidwa ntchito kunyamula nthunzi. Pofuna kukonza bwino ntchito ya chotenthetsera, ma heat sink okhala ndi mphamvu zabwino zotenthetsera kutentha nthawi zambiri amawonjezeredwa m'mapaipi kuti awonjezere malo otenthetsera kutentha kuti afulumizitse kutentha, ndikugwiritsa ntchito mafani kuti afulumizitse mpweya kuti achotse kutentha.

Kuti tikambirane za mfundo ya condenser, choyamba mvetsetsani lingaliro la condenser. Panthawi yothira, chipangizo chomwe chimasintha nthunzi kukhala madzi chimatchedwa condenser.

Mfundo yoziziritsira ya ma condenser ambiri: ntchito ya compressor yoziziritsira ndi kukanikiza nthunzi yotsika mphamvu kukhala nthunzi yotsika mphamvu, kotero kuti voliyumu ya nthunzi ichepe ndipo kupanikizika kuchuluke. Compressor yoziziritsira imapumira nthunzi yamadzimadzi yogwira ntchito yotsika mphamvu kuchokera ku evaporator, kukweza kupanikizika, ndikutumiza ku condenser. Imapindika kukhala madzi othamanga kwambiri mu condenser. Pambuyo poponderezedwa ndi valavu yopondereza, imakhala madzi okhudzidwa ndi kupanikizika. Madziwo atatha kutsika, amatumizidwa ku evaporator, komwe amatenga kutentha ndi kusungunuka kukhala nthunzi yokhala ndi kupsinjika kochepa, potero amamaliza kuzungulira kwa kuzizira.

1. Mfundo zazikulu za dongosolo loziziritsa

Pambuyo poti madzi oziziritsa atenga kutentha kwa chinthu chomwe chikuziziritsidwa mu evaporator, amasanduka nthunzi kukhala nthunzi yotsika komanso yotsika, yomwe imayamwa mu compressor yoziziritsira, kukakamizidwa kukhala nthunzi yotsika komanso yotsika, kenako n’kutulutsidwa mu condenser. Mu condenser, imaperekedwa ku malo ozizira (madzi kapena Mpweya) omwe amatulutsa kutentha, kusungunuka kukhala madzi othamanga kwambiri, kukakamizidwa kukhala refrigerant yotsika komanso yotsika ndi valavu yothira mpweya, kenako n’kulowa mu evaporator kachiwiri kuti itenge kutentha ndi nthunzi, kukwaniritsa cholinga cha kuzizira kwa kayendedwe ka mpweya. Mwanjira imeneyi, refrigerant imamaliza kuzungulira kwa kuzizira kudzera m’njira zinayi zoyambira monga kuzizira, kupsinjika, kuzizira, ndi kutsekereza m’dongosolo.

Mu dongosolo loziziritsira, evaporator, condenser, compressor ndi throttle valve ndi magawo anayi ofunikira a dongosolo loziziritsira. Pakati pawo, evaporator ndi chipangizo chomwe chimanyamula mphamvu yozizira. Refrigerant imatenga kutentha kuchokera ku chinthu chomwe chikuziziritsidwa kuti ikwaniritse firiji. Compressor ndi mtima ndipo imagwira ntchito yoyamwa, kukanikiza, ndi kunyamula nthunzi ya refrigerant. Condenser ndi chipangizo chomwe chimatulutsa kutentha. Chimasamutsa kutentha komwe kumayamwa mu evaporator pamodzi ndi kutentha komwe kumasinthidwa ndi ntchito ya compressor kupita ku malo ozizira. Valavu ya throttle imakoka ndikuchepetsa kupsinjika kwa refrigerant, imawongolera ndikulamulira kuchuluka kwa madzi oziziritsira omwe akuyenda mu evaporator, ndikugawa dongosololi m'magawo awiri, mbali ya kuthamanga kwambiri ndi mbali ya kuthamanga kochepa. Mu machitidwe enieni oziziritsira, kuwonjezera pa zigawo zinayi zazikulu zomwe zili pamwambapa, nthawi zambiri pamakhala zida zina zothandizira, monga ma solenoid valves, ogawa, owumitsa, osonkhanitsa, ma fusible plugs, owongolera kuthamanga ndi zigawo zina, zomwe zimagwiritsidwa ntchito kukonza magwiridwe antchito. Zotsika mtengo, zodalirika komanso zotetezeka.

2. Mfundo yosungira kutentha kwa nthunzi

Dongosolo loziziritsira la nthunzi lokhala ndi gawo limodzi limapangidwa ndi zigawo zinayi zazikulu: compressor yoziziritsira, condenser, evaporator ndi throttle valve. Amalumikizidwa motsatizana ndi mapaipi kuti apange dongosolo lotsekedwa. Refrigerant imazungulira mosalekeza mu dongosolo, imasintha momwe zinthu zilili, ndipo imasinthanitsa kutentha ndi dziko lakunja.

3. Zigawo zazikulu za dongosolo loziziritsa

Magawo oziziritsira akhoza kugawidwa m'mitundu iwiri malinga ndi mawonekedwe a condensation: magawo oziziritsira oziziritsidwa ndi madzi ndi magawo oziziritsira oziziritsidwa ndi mpweya. Malinga ndi cholinga chogwiritsira ntchito, akhoza kugawidwa m'mitundu iwiri: gawo limodzi loziziritsira ndi mtundu wa firiji ndi kutentha. Kaya mtundu wanji wapangidwa, umapangidwa ndi izi. Uli ndi zigawo zazikulu.

Chokondensa ndi chipangizo chomwe chimatulutsa kutentha. Chimasamutsa kutentha komwe kumayamwa mu evaporator pamodzi ndi kutentha komwe kumasinthidwa ndi ntchito ya compressor kupita ku malo ozizira. Valavu yolumikizira imakoka ndi kuchepetsa kuthamanga kwa refrigerant, ndipo nthawi yomweyo imawongolera ndikulamulira kuchuluka kwa madzi oziziritsa omwe amalowa mu evaporator, ndikugawa dongosololi m'magawo awiri, mbali ya kuthamanga kwambiri ndi mbali ya kuthamanga kochepa.
