1. Kodi mungasunge bwanji firiji ya malo osungiramo zinthu zozizira?
(1) Poyamba kugwiritsa ntchito chipangizo choziziritsira, samalani ngati mulingo wa mafuta a compressor uli 1/2 kuchokera pagalasi lowonera mafuta; ngati ukhondo wa mafuta odzola uli wabwino. Ngati zapezeka kuti mulingo wa mafuta watsika kuposa muyezo kapena mafuta odzola ndi odetsedwa kwambiri, ziyenera kuthetsedwa mwachangu kuti mafuta asawonongeke.
(2) Pa chipangizo choziziritsira mpweya: yeretsani pamwamba pa choziziritsira mpweya pafupipafupi kuti chikhale pamalo abwino osinthira kutentha.
(3) Pa chipangizo choziziritsidwa ndi madzi: madzi ozizira ayenera kuwonedwa pafupipafupi. Ngati madzi ozizira ndi odetsedwa kwambiri, ayenera kusinthidwa.
(4) Samalani kuti muwone ngati madzi ozizira a chipangizocho akuyenda, akutuluka, akudontha kapena akutuluka. Ngati alipo, ayenera kuthetsedwa nthawi yake.
(5) Kaya momwe pampu yamadzi imagwirira ntchito ndi yabwinobwino; ngati chosinthira cha valavu cha makina oziziritsira madzi chikugwira ntchito bwino; ngati momwe nsanja yoziziritsira ndi fani zimagwirira ntchito ndi zabwinobwino.
(6) Pa evaporator yoziziritsidwa ndi mpweya: ndikofunikira kuwona ngati mkhalidwe wa kusungunuka kwa madzi uli wabwinobwino; ngati mphamvu ya kusungunuka kwa madzi ili yabwino, ndipo ngati pali vuto, liyenera kuthetsedwa nthawi yake.
(7) Samalani kuti muwone momwe compressor ikuyendera, onani ngati kutentha kwa utsi ndi mphamvu ya mpweya zili mkati mwa mulingo woyenera, ndipo thananani nazo pakapita nthawi ngati pali vuto lililonse.
2. Dziwani ngati momwe condenser imagwirira ntchito ndi yachibadwa
Ngati simukudziwa ngati momwe condenser imagwirira ntchito ndi yabwinobwino, mutha kuwona ngati ikugwira ntchito bwino mwa kuzindikira kusiyana kwa kutentha pakati pa condenser ndi malo ozizira. Kutentha kwa condenser yoziziritsidwa ndi madzi ndi kokwera ndi 4 ~ 6 ℃ kuposa kutentha kwa madzi ozizira, ndipo kutentha kwa condenser yoziziritsidwa ndi evaporative kumakhudzana ndi kutentha kwa mpweya, komwe kuli kokwera ndi pafupifupi 5 ~ 10 ℃ kuposa kutentha kwa babu lonyowa lakunja. Kutentha kwa condenser yoziziritsidwa ndi mpweya ndi kokwera ndi 8 ~ 12 ℃ kuposa kutentha kwa mpweya.
3. Kulamulira kutentha kwa compressor suction
Kutentha kwamphamvu kwa compressor mu makina oziziritsira nthawi zambiri kuyenera kulamulidwa mkati mwa 5 mpaka 15 °C, ndipo kutentha kwa compressor mu makina oziziritsira a Freon nthawi zambiri kuyenera kukhala pafupifupi 15 °C kuposa kutentha kwa nthunzi, koma kwenikweni, sikuyenera kupitirira 15 °C. Chifukwa kutentha kwa nthunzi kwa makina oziziritsira m'malo osiyanasiyana ozizira ndi kosiyana, kutentha kwa nthunzi nakonso ndi kosiyana.
4. Kuopsa kwa kutentha kwa compressor komwe kuli kokwera kwambiri kapena kotsika kwambiri
Ngati kutentha kwa compressor kuli kokwera kwambiri, kuchuluka kwa compressor komwe kumayamwa kudzawonjezeka, mphamvu yozizira idzachepa, ndipo kutentha kwa utsi kudzawonjezeka;
Ngati kutentha kwa compressor kuli kotsika kwambiri, madzi ambiri akhoza kuperekedwa ku makina oziziritsira, ndipo firiji yamadzi sidzaphikidwa mokwanira mu evaporator, zomwe zingayambitse kunyowa. Samalani kusintha nthawi iliyonse.
5. Ndiyenera kuchita chiyani ngati makina oziziritsira a m'chipinda chosungiramo zinthu zozizira ali ndi fluorine yokwanira?
Pa nthawi yogwira ntchito ya makina oziziritsira m'malo osungiramo zinthu zozizira, nthawi zambiri, makina oziziritsira amatuluka chifukwa cha kusowa kwa makina oziziritsira kapena panthawi yokonza (monga kusintha mafuta, kutulutsa mpweya, kusintha choumitsira fyuluta, ndi zina zotero), zomwe zimapangitsa kuti makina oziziritsira asakwanire. Pakadali pano, ayenera kuwonjezeredwa nthawi yake kuti atsimikizire kuti makina oziziritsira akugwira ntchito bwino.
Dongosolo loziziritsira limawonjezeredwa ndi refrigerant, ndipo kukonzekera musanayike chaji ndi chimodzimodzi ndi mfundo yaikulu yoyikira chaji yatsopano, kupatula kuti pali refrigerant mu dongosololi musanayike chaji, ndipo compressor ikhoza kugwirabe ntchito.
Dongosolo loziziritsira limawonjezeredwa ndi refrigerant, yomwe nthawi zambiri imayikidwa kuchokera kumbali ya compressor yomwe imakhala ndi mphamvu yochepa.
Njira yogwiritsira ntchito makina oziziritsira ozizira imakhala ndi fluorine yocheperako: compressor ikayimitsidwa, ikani silinda yoziziritsira pansi, gwiritsani ntchito mapaipi awiri a fluorine mukadzaza firiji, lumikizani valavu yokonza motsatizana pakati pawo, kenako Lumikizani mbali imodzi ya chitoliro cha fluoride ku silinda, ndi mbali inayo ku njira yogwiritsira ntchito zinthu zambiri ya valavu yoziritsira ya compressor. Choyamba tsegulani valavu ya silinda ya freon, gwiritsani ntchito nthunzi yoziziritsira kuti mutulutse mpweya mu chitoliro cha fluorine, kenako limbitsani kulumikizana pakati pa chitoliro cha fluorine ndi njira yogwiritsira ntchito zinthu zambiri ya valavu yoziritsira ya compressor.
Tsegulani njira yogwiritsira ntchito zinthu zambiri ya valavu yopopera compressor m'njira zitatu. Pamene valavu yoyezera kuthamanga kwa mpweya ikuwoneka kuti yakhazikika, tsekani kwakanthawi valavu ya silinda ya freon. Yambitsani compressor kuti igwire ntchito kwa mphindi pafupifupi 15, ndikuwona ngati kuthamanga kwa mpweya kuli mkati mwa mulingo wofunikira. Ngati kuthamanga kwa mpweya sikungatheke, valavu ya silinda ya freon ikhoza kutsegulidwanso, ndipo firiji ipitiliza kuwonjezeredwa mu dongosolo loziziritsira mpaka kuthamanga kwa mpweya kufikire. Popeza njira iyi yowonjezerera mpweya mufiriji ndi yakuti firiji imayikidwa mu mawonekedwe a nthunzi yonyowa, ndikofunikira kutsegula valavu ya silinda ya Freon bwino kuti compressor isatuluke mu nyundo yamadzimadzi. Kuchaja kukakwaniritsa zofunikira, tsekani nthawi yomweyo valavu ya silinda ya freon, kenako lolani firiji yotsala mu chitoliro cholumikizira kuti ilowe mu dongosolo momwe mungathere, ndipo potsiriza tsekani njira yogwiritsira ntchito zinthu zambiri, siyani kugwira ntchito kwa compressor, ndipo ntchito yochaja mpweya mufiriji yatha. Njirayi ili ndi liwiro lofulumira kuyitanitsa, koma ili ndi chitetezo chabwino pamene firiji yomwe ili mufiriji siili yokwanira ndipo ikufunika kuwonjezeredwa.
6. Kodi ndiyenera kuchita chiyani ngati ndikufuna kukonzanso desiccant ya silica gel?
Mlingo wa kuyamwa kwa chinyezi wa silica gel desiccant ndi pafupifupi 30%. Ndi kristalo yopanda poizoni, yopanda fungo komanso yosawononga yokhala ndi ma pores osalala, ma pores osalala, mtundu woyambirira ndi kusintha kwa mtundu. Silica gel yokhala ndi ma coarse-pored imayamwa chinyezi mwachangu, ndi yosavuta kukhuta, ndipo imakhala ndi nthawi yochepa yogwiritsira ntchito: silica gel yokhala ndi ma pores osalala imayamwa chinyezi pang'onopang'ono ndipo imagwiritsidwa ntchito nthawi yayitali; silica gel yosintha mtundu imakhala yabuluu ikakhala youma, ndipo pang'onopang'ono imasintha kukhala buluu wopepuka, wofiirira-wofiira, ndipo pamapeto pake ikakhala yofiirira ikayamwa chinyezi imakhala yofiira ndipo imataya mphamvu ya hygroscopic.
Kukonzanso kwa desiccant ya silica gel kungachitike poika silika gel yokonzeka kuumitsidwa ndikusinthidwanso mu uvuni kuti itenthedwe ndikubwezeretsedwanso. Ikani kutentha kwa uvuni kufika pa 120 ~ 200 °C, ndikuyika nthawi yotenthetsera kufika pa maola 3 ~ 4. Pambuyo pokonzanso, desiccant ya silica gel imatha kuchotsa chinyezi chomwe chimalowa mkati ndikubwezeretsa momwe chinalili poyamba. Pambuyo potseka tinthu tating'onoting'ono tosweka, imatha kuyikidwa mu fyuluta yowumitsa kuti igwiritsidwe ntchito mobwerezabwereza.
