Mfundo yogwirira ntchito ya steam compression refrigeration system ya automobile air conditioning
Mfundo yogwirira ntchito ya makina oziziritsira mpweya wamagalimoto pamagalimoto makamaka imaphatikizapo njira zinayi zofunika: compression process, condensation process, expansion process and evaporation process.
Njira yopondereza: Compressor imakoka kutentha kochepa komanso kutsika kwa mpweya mufiriji kumbali yotsika ya evaporator, ndikuyiyika mufiriji yotentha kwambiri, kenako ndikuitumiza ku condenser kuti izizirike. Izi zimawonjezera kutentha ndi kupanikizika kwa refrigerant.
Njira ya condensation : Refrigerant yotentha kwambiri komanso yothamanga kwambiri imatayidwa ndi fani ndi mphepo yopangidwa ndi galimoto mu condenser, ndikuyika mufiriji yamadzimadzi pa kutentha kwapakati komanso kuthamanga kwambiri. Ntchito ya condenser ndi kusamutsa kutentha kwa firiji kumalo akunja kuti kuziziritsa.
Njira yowonjezera : Pamene firiji yamadzimadzi idutsa mu valve yowonjezera kapena chubu cha throttle chubu, kuthamanga ndi kutentha kumatsika kwambiri ndikukhala kutentha kochepa komanso mpweya wochepa wonyowa. Izi zimapangitsa kuti gawo lina la firiji lisungunuke, ndikupanga chisakanizo cha gasi-madzi okonzeka kuyamwa kutentha.
Njira ya evaporation : Kusakaniza kwa gasi-madzi a furiji kumalowa mu evaporator, kumayamwa kutentha m'ngoloyo, ndipo kumasanduka nthunzi mufiriji yotentha kwambiri komanso yotsika mphamvu. The evaporator ndi bwino kutentha exchanger, amene amachotsa kutentha otengedwa ndi refrigerant mu evaporation ndondomeko kuchokera chonyamulira kudzera mu chitoliro chamkati, kuti akwaniritse kuzirala .
Zigawo za makina opangira mpweya wotenthetsera mpweya wamagalimoto amaphatikizapo compressor, condenser, valavu yokulitsa (kapena chubu lopumira), evaporator ndi zinthu zowongolera zomwe zimayenderana. Pamodzi, zigawozi zimapanga njira yotsekedwa yotsekedwa yomwe firiji imayenda mosalekeza, ndikumaliza kusintha kuchokera ku gasi kupita kumadzi kupita ku gasi .
Kagwiritsidwe ntchito ka steam compression refrigeration system ya automobile air conditioning makamaka ndi makina oziziritsira mpweya m'galimoto. Kupyolera mu dongosololi, mpweya wa galimoto ukhoza kuchepetsa kutentha m'galimoto ndikupereka malo oyendetsa bwino.
Makina otenthetsera mpweya wagalimoto yamagalimoto ndi chipangizo chomwe chimagwiritsa ntchito firiji kuti chizizungulira munjira yosinthira kutentha, chomwe chimagwiritsidwa ntchito kwambiri kuchepetsa kutentha kwagalimoto. Dongosololi limapangidwa makamaka ndi zigawo izi: kompresa, condenser, valavu yowonjezera, evaporator ndi mapaipi ndi mavavu olumikiza mbali izi.
Mfundo yogwira ntchito
Njira yophatikizira: Compressor imakoka kutentha pang'ono komanso kutsika kwa mpweya mufiriji mu evaporator, ndikuyiyika mufiriji yotentha kwambiri ndi mpweya wambiri, kenako ndikuitumiza ku condenser kuti izizirike.
Njira ya condensation : Kutentha kwambiri komanso kuthamanga kwambiri kwa mpweya mufiriji mu condenser kupita ku sing'anga yozizira (nthawi zambiri mpweya kapena madzi) kutulutsa kutentha, kulowa mufiriji yamadzimadzi.
Njira yowonjezera : Pamene firiji yamadzimadzi idutsa mu valve yowonjezera, kuthamanga ndi kutentha kumatsika ndikukhala kutentha kochepa komanso kutsika kwa mpweya wonyowa.
Njira ya evaporation: kutentha kochepa komanso kutsika kwa mpweya wonyowa mu evaporator, kumatenga kutentha m'galimoto, kumasanduka nthunzi mufiriji ya mpweya, kenako kumakokedwanso ndi kompresa kuti amalize kuzungulira mufiriji.
firiji
Refrigerant wamba ndi R-134a (tetrafluoroethane), yomwe imatenga kutentha kwambiri ikasinthidwa kuchoka kumadzi kupita ku gasi mu evaporator, zomwe zimapangitsa kuzirala.
Mbiri yakale komanso chitukuko chaukadaulo
Mfundo yaikulu ya galimoto yoyendetsa mpweya wa refrigeration system ndi yofanana ndi ya air conditioning ya m'nyumba, yomwe imagwiritsa ntchito kusintha kwa dziko la firiji kuti ikwaniritse firiji. Ndi chitukuko chaukadaulo, makina amakono owongolera mpweya wamagalimoto alinso ndi masensa osiyanasiyana ndi machitidwe owongolera kuti akwaniritse kuwongolera kutentha komanso kugwiritsa ntchito mphamvu moyenera.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
