Chiyambi

Makina ogwiritsira ntchito centrifugal amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo makina a HVAC, ma compressor a mpweya, ndi makina a mafakitale. Makinawa amadalira kusamutsa bwino kutentha kuchokera ku sing'anga imodzi kupita ku ina, ndipo kugwiritsa ntchito ma refrigerant ndikofunikira kwambiri pa njirayi. Ma refrigerant amagwira ntchito yofunika kwambiri pakusunga kutentha kwabwino ndikuwonetsetsa kuti makina ogwiritsira ntchito centrifugal akuyenda bwino.

Kumvetsetsa Makina a Centrifugal

Makina oyendera magetsi (centrifugal) ndi mtundu wa makina ozungulira omwe amagwiritsa ntchito mphamvu ya centrifugal kusuntha madzi kapena mpweya. Amapangidwa ndi zigawo zosiyanasiyana, kuphatikizapo impeller, casing, ndi ma bearing. Impeller imagwira ntchito yofunika kwambiri popanga mphamvu ya centrifugal yofunikira, pomwe casing imathandiza kuwongolera kuyenda kwa madzi. Makina awa apangidwa kuti azigwira ntchito yothamanga kwambiri pamene pakufunika kusamutsa kutentha kosalekeza komanso kogwira mtima.

Ntchito Yofunika Kwambiri ya Mafiriji

Mafiriji ndi zinthu zomwe zimakhala ndi mphamvu ya thermodynamic zomwe zimawathandiza kuyamwa kutentha kuchokera ku chinthu china ndikuchitulutsa mu china. Amagwiritsidwa ntchito kwambiri mu air conditioner, mafiriji, ndi ma heat pump. Mafiriji amasinthidwa pang'onopang'ono kuchokera ku madzi kupita ku gasi ndi kumbuyo, zomwe zimawalola kuyamwa ndi kutulutsa mphamvu ya kutentha bwino. Ndiwo makamaka omwe ali ndi udindo wosunga kutentha komwe kukufunika mu dongosolo.

Malo Owonjezera Ma Refrigerant mu Makina a Centrifugal

Mu makina ozungulira, ma refrigerant nthawi zambiri amawonjezedwa pamalo enaake kuti azitha kusamutsa kutentha komanso kugwiritsa ntchito bwino makina. Malo ofala kwambiri owonjezerera ma refrigerant ndi gawo la evaporator la makina, komwe refrigerant imayamwa kutentha kuchokera ku sing'anga yomwe ikuzizira.

Mkati mwa gawo la evaporator, refrigerant imazungulira mosalekeza, kutenga mphamvu ya kutentha ndi kupsa kukhala mpweya. Mpweya uwu umapita ku compressor, komwe umakanikizidwa kuti uwonjezere kutentha ndi kupanikizika kwake. Kuchokera ku compressor, mpweya wopanikizika kwambiri umapita ku condenser, komwe umatulutsa kutentha kumalo ozungulira ndikuwunjikananso kukhala madzi. Pomaliza, refrigerant yotsekedwa imabwerera ku evaporator kuti ibwerezenso kayendedwe kake.

Zinthu Zomwe Zimakhudza Njira Yowonjezerera Mafiriji

Zinthu zingapo zimakhudza njira yowonjezeramo refrigerant mu makina ozungulira. Mtundu wa refrigerant yomwe ikugwiritsidwa ntchito, momwe imagwiritsidwira ntchito, ndi kutentha komwe kumafunidwa zonse zimathandiza pakudziwa njira yabwino kwambiri yowonjezeramo refrigerant. Kuphatikiza apo, zinthu monga kapangidwe ka makina, kusintha kwa katundu, ndi momwe zinthu zilili zingakhudzire mphamvu ya refrigerant komanso momwe makinawo amagwirira ntchito.

Zigawo Zofunika Kwambiri Zokhudzana ndi Kuwonjezera kwa Refrigerant

1. Vavu yokulitsa: Vavu yokulitsa imalamulira kuyenda kwa refrigerant mu evaporator, kuonetsetsa kuti kuchuluka koyenera kwa refrigerant kumalowa mu dongosolo. Imawongolera kuthamanga kwa refrigerant ndikusunga liwiro lokhazikika kuti kutentha kusamutsidwe bwino.

2. Accumulator: Accumulator imagwira ntchito ngati thanki yosungiramo firiji yochulukirapo panthawi yogwira ntchito ya system. Imaletsa refrigerant yamadzimadzi kulowa mu compressor, motero imaiteteza ku kuwonongeka komwe kungachitike.

3. Galasi lowonera: Galasi lowonera ndi zenera lowonekera bwino lomwe limalola kuyang'ana bwino kayendedwe ka refrigerant. Limathandiza kuzindikira zinthu zilizonse zosafunikira, monga kukhalapo kwa mpweya kapena zinthu zodetsa m'dongosolo.

4. Masensa opanikizika: Masensa opanikizika amapereka chidziwitso cha nthawi yeniyeni chokhudza kuthamanga kwa mpweya mufiriji mkati mwa dongosolo. Deta iyi imathandiza kuyang'anira ndikuwongolera njira yowonjezera mpweya mufiriji, kuonetsetsa kuti imakhalabe mkati mwa mulingo womwe mukufuna.

5. Choumitsira makina oyeretsera madzi: Chigawochi chimachotsa chinyezi, dothi, ndi zinthu zina zodetsa mufiriji chisanalowe mu evaporator. Chimathandiza kusunga magwiridwe antchito komanso moyo wautali wa dongosololi popewa kuwonongeka komwe kungachitike chifukwa cha zinthu zodetsa.

Ubwino Wowonjezera Zinthu Zozizira Bwino

Kuwonjezera ma refrigerant oyenera mu makina oyendera magetsi kumapereka ubwino wambiri. Choyamba, kumaonetsetsa kuti kutentha kumasamutsidwa bwino, zomwe zimathandiza makinawo kukwaniritsa ndikusunga kutentha komwe akufunikira nthawi zonse. Izi zimapangitsa kuti makinawo azigwira bwino ntchito komanso kuchepetsa kugwiritsa ntchito mphamvu. Kachiwiri, zimathandiza kukulitsa nthawi ya moyo wa makinawo popewa mavuto monga kutentha kwambiri kwa compressor, komwe kungachitike chifukwa cha kuchuluka kosakwanira kwa ma refrigerant. Pomaliza, kuwonjezera ma refrigerant oyenera kumachepetsa chiopsezo cha kuwonongeka kwa makina ndi kukonza ndalama zambiri, zomwe zimapangitsa kuti pakhale ntchito zambiri komanso kusunga ndalama.

Kusunga Ma Refrigerant Abwino Kwambiri

Kusamalira ndi kuyang'anira nthawi zonse ndikofunikira kuti makina oziziritsira apitirize kukhala ndi mulingo woyenera wa mafiriji m'makina ozungulira. Kuwunika pafupipafupi kuyenera kuchitika kuti zitsimikizire kuti makina oziziritsira ali ndi mphamvu yoyenera komanso kuzindikira kutayikira kapena zolakwika zilizonse. Kuphatikiza apo, ndikofunikira kutsatira malangizo a wopanga okhudza mitundu ya makina oziziritsira, mphamvu ya makina, ndi njira zosamalira zomwe amalimbikitsa. Mwa kutsatira malangizo awa ndikuthana ndi mavuto aliwonse mwachangu, moyo wautali ndi magwiridwe antchito a makina ozungulira azitha kukhala apamwamba.

Mapeto

Kuwonjezera ma refrigerant mu makina oyendera magetsi ndi njira yofunika kwambiri yomwe imatsimikizira kusamutsa kutentha bwino komanso magwiridwe antchito a makina. Kumvetsetsa malo, zinthu zomwe zimakhudza njirayi, ndi zigawo zazikulu zomwe zimakhudzidwa ndikofunikira kwambiri kuti ma refrigerant akhale ndi milingo yabwino kwambiri. Kuwonjezera ma refrigerant moyenera kumabweretsa zabwino zambiri, kuphatikizapo kugwiritsa ntchito bwino mphamvu, nthawi yayitali ya makina, komanso kuchepetsa zoopsa za kuwonongeka kwa makina. Mwa kuika patsogolo kukonza ndikutsatira malangizo a opanga, kuthekera konse kwa makina oyendera magetsi kumatha kuchitika, zomwe zimathandiza kuti pakhale kupanga bwino komanso kusunga ndalama zambiri.
