1-Kukhazikitsa malo osungiramo zinthu zozizira ndi zoziziritsira mpweya
1. Posankha malo onyamulira, choyamba ganizirani malo omwe mpweya umayendera bwino, kenako ganizirani momwe malo osungiramo zinthu ozizira alili.
2. Mpata pakati pa choziziritsira mpweya ndi bolodi losungiramo zinthu uyenera kukhala waukulu kuposa makulidwe a choziziritsira mpweya.
3. Mabotolo onse oimika a choziziritsira mpweya ayenera kumangidwa mwamphamvu, ndipo chotsekeracho chiyenera kugwiritsidwa ntchito kutseka mabowo a mabotolo ndi mabotolo oimika kuti apewe kuzizira ndi kutuluka kwa mpweya.
4. Ngati fani ya padenga ndi yolemera kwambiri, chitsulo cha ngodya cha nambala 4 kapena 5 chiyenera kugwiritsidwa ntchito ngati mtanda, ndipo lintel iyenera kufalikira padenga lina ndi mbale ya pakhoma kuti ichepetse katundu.
2-kukhazikitsa ndi kukhazikitsa chipangizo choziziritsira
1. Ma compressor onse a semi-hemetic ndi fully hemetic ayenera kukhala ndi cholekanitsa mafuta, ndipo mafuta okwanira ayenera kuwonjezeredwa mu mafutawo. Ngati kutentha kwa nthunzi kuli kotsika kuposa madigiri 15, cholekanitsa gasi ndi madzi chiyenera kuyikidwa ndipo choyezera choyenera chiyenera kuyikidwa.
Yesani mafuta oziziritsira.
2. Pansi pa compressor payenera kuyikidwa ndi mpando wa rabara woyamwa kugunda kwamphamvu.
3. Kukhazikitsa chipangizochi kuyenera kusiya malo oti chikonzedwe, zomwe ndi zosavuta kuwona momwe zida ndi ma valve zimasinthira.
4. Choyezera kuthamanga kwambiri chiyenera kuyikidwa pa tee ya valavu yosungira madzi.
3. Ukadaulo wokhazikitsa mapaipi mufiriji:
1. M'mimba mwake mwa chitoliro cha mkuwa muyenera kusankha motsatira momwe chitoliro cha compressor chimalumikizirana ndi valavu yotulutsira mpweya. Ngati kusiyana pakati pa condenser ndi compressor kupitirira mamita atatu, m'mimba mwake mwa chitolirocho kuyenera kuwonjezeka.
2. Sungani mtunda pakati pa pamwamba pa mpweya wokoka mpweya wa condenser ndi khoma kupitirira 400mm, ndipo sungani mtunda pakati pa malo otulutsira mpweya ndi chotchinga kupitirira mamita atatu.
3. M'mimba mwake mwa mapaipi olowera ndi otulutsira madzi mu thanki yosungiramo madzi muyenera kutengera m'mimba mwake mwa mapaipi otulutsira madzi ndi otulutsira madzi omwe alembedwa pa chitsanzo cha unit.
4. Chitoliro choyamwa cha compressor ndi chitoliro chobwezera cha fan yozizira sichiyenera kukhala chochepera kukula komwe kwawonetsedwa mu chitsanzo kuti muchepetse kukana kwamkati kwa chitoliro choyatsira mpweya.
5. Chitoliro chilichonse chotulutsira madzi chiyenera kudulidwa kukhala bevel ya madigiri 45, ndikuyikidwa pansi pa chitoliro cholowera madzi kuti chiyike kotala la mulifupi wa chitoliro cha malo osinthira.
6. Chitoliro chotulutsa mpweya ndi chitoliro chobwerera mpweya ziyenera kukhala ndi malo otsetsereka. Pamene malo a condenser ali okwera kuposa a compressor, chitoliro chotulutsa mpweya chiyenera kutsetsereka kupita ku condenser ndipo mphete yamadzimadzi iyenera kuyikidwa pa doko la utsi la compressor kuti isatseke.
Mpweya ukazizira ndi kusungunuka, umabwerera ku malo otulutsira utsi amphamvu, ndipo madziwo amakanikizidwa makina akayambiranso.
7. Mphepete yooneka ngati U iyenera kuyikidwa pamalo otulukira mpweya wobwerera wa fan yoziziritsira. Mphepete yobwerera iyenera kutsetsereka kupita ku compressor kuti mafuta abwerere bwino.
8. Valavu yowonjezera iyenera kuyikidwa pafupi momwe mungathere ndi choziziritsira mpweya, valavu ya solenoid iyenera kuyikidwa mopingasa, thupi la valavu liyenera kukhala loyima ndikuyang'ana mbali ya madzi otuluka.
9. Ngati kuli kofunikira, ikani fyuluta pa chingwe chobwezera mpweya cha compressor kuti dothi lomwe lili mu dongosolo lisalowe mu compressor ndikuchotsa chinyezi chomwe chili mu dongosolo.
10. Musanamange sodium ndi lock nuts zonse mufiriji, zipukuteni ndi mafuta ophikira kuti ziwonjezere kutseka, zipukuteni bwino mutazimangirira, ndikutseka chitseko chilichonse mwamphamvu.
11. Phukusi lozindikira kutentha la valavu yokulitsa limamangiriridwa pa 100mm-200mm kuchokera pamalo otulukira a evaporator ndi zipini zachitsulo, ndipo limakulungidwa mwamphamvu ndi chotetezera kutentha cha zigawo ziwiri.
12. Pambuyo poti kulumikiza makina onse kumalizidwa, mayeso oletsa mpweya ayenera kuchitika, ndipo mbali ya kupanikizika kwakukulu idzadzazidwa ndi nayitrogeni ya 1.8MP. Mbali ya kupanikizika kochepa idzadzazidwa ndi nayitrogeni ya 1.2MP. Gwiritsani ntchito madzi a sopo kuti muwone ngati pali kutuluka madzi panthawi ya kupanikizika, yang'anani mosamala malo olumikizirana, ma flange ndi ma valve, ndikusunga kupanikizika kwa maola 24 mutamaliza pang'ono popanda kuchepetsa kupanikizika.
