Chifukwa chiyani compressor yosungiramo zinthu zozizira imafunika?

1-Zida zosungiramo zinthu zozizira: Chipale chofewa pa doko la ndege yobwerera ya compressor chimasonyeza kuti kutentha kwa mpweya wobwerera kwa compressor kuli kotsika kwambiri. Ndiye n’chiyani chingapangitse kutentha kwa mpweya wobwerera kwa compressor kukhala kotsika kwambiri?

Ndizodziwika bwino kuti ngati kuchuluka ndi kuthamanga kwa mtundu womwewo wa refrigerant zasinthidwa, kutentha kudzakhala ndi magwiridwe osiyanasiyana. Izi zikutanthauza kuti, ngati refrigerant yamadzimadzi imatenga kutentha kochulukirapo, kuthamanga, kutentha ndi kuchuluka kwa mtundu womwewo wa refrigerant kudzakhala kwakukulu. Ngati kutentha kumayamwa pang'ono, kuthamanga, kutentha ndi kuchuluka kudzakhala kochepa.

Izi zikutanthauza kuti, ngati kutentha kwa mpweya wobwerera kwa compressor kuli kotsika, nthawi zambiri kumawonetsa mpweya wobwerera wochepa komanso kuchuluka kwa mpweya wozizira komweko. Chifukwa chachikulu cha vutoli ndichakuti firiji yomwe ikuyenda kudzera mu evaporator singathe kuyamwa kutentha komwe kumafunika kuti ikule yokha mpaka kufika pamlingo wokhazikika wa kuthamanga ndi kutentha, zomwe zimapangitsa kuti kutentha kwa mpweya wobwerera, kuthamanga ndi kuchuluka kwake kukhale kochepa.

Pali zifukwa ziwiri za vutoli:

1. Kupereka madzi mufiriji ya throttle valve ndi kwabwinobwino, koma evaporator singathe kuyamwa kutentha mwachizolowezi kuti ipereke kukulitsa kwa refrigerant.

2. Evaporator imayamwa kutentha mwachizolowezi, koma mphamvu ya refrigerant ya throttle valve ndi yochuluka kwambiri, ndiko kuti, madzi otuluka mu refrigerant ndi ochuluka kwambiri. Nthawi zambiri timamvetsa kuti fluorine yochuluka kwambiri, ndiko kuti, fluorine yochuluka kwambiri ingayambitsenso kupanikizika kochepa.

2- Zipangizo zosungiramo zinthu zozizira: Mpweya wobwerera ku compressor chifukwa cha fluorine yosakwanira

1. Chifukwa cha kuchuluka kochepa kwa madzi mufiriji, firijiyi imayamba kufutukuka pamalo oyamba ofutukuka ikatuluka kumbuyo kwa valavu yopukutira. Chipale chofewa kwambiri pamutu wogawa madzi kumbuyo kwa valavu yofutukuka nthawi zambiri chimachitika chifukwa cha kusowa kwa fluorine kapena kusakwanira kwa valavu yofutukuka. Kufutukuka kochepa kwa firiji sikudzagwiritsa ntchito malo onse a evaporator, ndipo kutentha kochepa kokha ndiko kudzapangidwa m'deralo mu evaporator. Madera ena adzafutukuka mofulumira chifukwa cha kuchuluka kochepa kwa refrigerant, zomwe zimapangitsa kuti kutentha kwa m'deralo kukhale kochepa kwambiri, zomwe zimapangitsa kuti evaporator ifumbwe.

Pambuyo pa chisanu chapafupi, chifukwa cha kupangika kwa gawo loteteza kutentha pamwamba pa evaporator ndi kusinthana kwa kutentha kochepa m'derali, kufutukuka kwa refrigerant kudzasamutsidwira kumadera ena, ndipo evaporator yonse idzazizira pang'onopang'ono kapena kuzizira. Evaporator yonse ipanga gawo loteteza kutentha, kotero kufutukukako kudzafalikira ku chitoliro chobwezera compressor, zomwe zimapangitsa kuti compressor ibweze mpweya ku chisanu.

2. Chifukwa cha kuchuluka kochepa kwa refrigerant, kuthamanga kwa evaporator kumakhala kochepa, zomwe zimapangitsa kutentha kochepa kwa evaporator, zomwe zimapangitsa kuti evaporator isungunuke ndikupanga gawo loteteza kutentha, ndipo malo okulirapo adzasamutsidwira ku mpweya wobwerera wa compressor, zomwe zimapangitsa kuti compressor ibwerere ku chisanu. Mfundo zonse ziwiri zomwe zili pamwambapa ziwonetsa kuti evaporator yatenthedwa isanatenthedwe mpweya wobwerera wa compressor.
Ndipotu, nthawi zambiri, pa chochitika cha frosting, mumangofunika kusintha valavu yodutsa mpweya wotentha. Njira yeniyeni ndikutsegula chivundikiro chakumbuyo cha valavu yodutsa mpweya wotentha, kenako gwiritsani ntchito wrench ya hexagonal No. 8 kuti mutembenuzire nati yosinthira mkati mozungulira wotchi. Njira yosinthira siyenera kukhala yachangu kwambiri. Nthawi zambiri, idzayimitsidwa mutatembenuza theka la bwalo. Lolani dongosolo liziyenda kwakanthawi kuti muwone momwe frosting ilili musanasankhe ngati mupitiliza kusintha. Yembekezerani mpaka ntchitoyo itakhazikika ndipo frosting ya compressor itatha musanamange chivundikiro cha kumapeto.
Kwa mitundu yosakwana ma cubic metres 15, popeza palibe valavu yodutsa mpweya wotentha, ngati vuto la frosting ndi lalikulu, kuthamanga koyambira kwa switch ya pressure ya fan condensing kumatha kuwonjezeredwa moyenera. Njira yeniyeni ndikupeza kaye switch ya pressure, kuchotsa chidutswa chaching'ono cha pressure switch adjustment nati, kenako gwiritsani ntchito screwdriver yopingasa kuti muzungulire mozungulira wotchi. Kusintha konse kuyeneranso kuchitika pang'onopang'ono. Sinthani theka la bwalo kuti muwone momwe zinthu zilili musanasankhe ngati mungasinthe.
