1, kuyatsa firiji musanatulutse makina oziziritsa sikokwanira
Musanayambe kuchaja firiji, makina oziziritsira mkati mwa silinda ya compressor, condenser, evaporator, ndi makina opopera akhala odzaza ndi mpweya, kuti mpweya uwu usachotsedwe musanayambe kuchaja firiji, kufunika kwa vacuum ya makina oziziritsira, nthawi zina chifukwa cha zifukwa zomveka komanso zodziyimira pawokha, makina oziziritsira sakwanira kuchapa, osati molingana ndi zofunikira za makinawo, pali mpweya wochepa mu makinawo.
2, chochaja choziziritsira ndi
Mufiriji, makina oziziritsira asanayambe kudzaza firiji, chubucho chimagwiritsidwa ntchito podzaza mpweya, chifukwa cha zifukwa zomwe anthu amapanga, monga kudzaza firiji, palibe utsi ngakhale mpweya uli mkati mwa chipindacho, wolumikizidwa mwachindunji ku makina oziziritsira, mpweya uwu ndi mphamvu imodzi yokha yoziziritsira mu makina oziziritsira.
3, mu dongosolo la firiji yokonzedwa yosakanikirana ndi mpweya wosakanizidwa ndi condensable
Makina oziziritsira amagwira ntchito kwa nthawi yayitali, ndipo amafunika kuyang'aniridwa ndi kukonzedwa kapena kutsukidwa ndi kusinthidwa, kotero nthawi zina amafunika kuchotsedwa kwa makina kapena mapaipi a mpweya nthawi zambiri amakhala akuphwanyidwa ndikuyikidwa mu makina oziziritsira, mkati.
4, kuchokera mumlengalenga wakunja kupita mu dongosolo lamkati
Mu makina ena oziziritsira, ngati kuthamanga kwa ntchito kuli kotsika kuposa kuthamanga kwa mpweya, mpweya wa mumlengalenga umalowa mu makina oziziritsira kudzera m'mipata yosiyanasiyana. Mipata iyi imagawidwa m'mitundu yosiyanasiyana ya ma valve, ma compressor, osalumikizidwa ndi malo ena ambiri.
5, kuchokera ku zotsatira za mankhwala a refrigerant
Mu dongosolo loziziritsira la ammonia, ammonia yoziziritsira pa kutentha ndi kupanikizika kwina imatha kusungunuka kukhala ammonia ndi haidrojeni ndipo kusungunuka kwake ndi kutentha kwa digiri 1 ndi kukakamizidwa kukhala ubale wabwino, kutentha ndi kupanikizika kwakukulu, kusungunuka kwa ammonia kumakhala kwakukulu. Mu dongosolo loziziritsira la Freon, Freon ikhoza kusakanikirana mu dongosolo ndi zodetsa mu reaction ya mankhwala, zomwe zimapangitsa kuti mpweya wosazizira ukhale wozizira. Mwachitsanzo, R12 imachitapo kanthu ndi madzi pansi pa mikhalidwe ina kuti ipange carbon dioxide.
