Mafiriji owonetsera zakumwa pazitseko zagalasi ndi ofunikira kwambiri m'makampani ogulitsa zinthu ku HORECA ndi ogulitsa. Amaonetsetsa kuti chakudya ndi zakumwa zimazizira komanso zimakopa makasitomala. Komabe, mayunitsi awa amatha kukhala ndi zolakwika zomwe zimachitika nthawi zambiri. Bukuli likufotokoza mavutowa ndi mayankho awo. Kupatula kuthetsa mavuto a mafiriji owonetsera zakumwa omwe ali ndi vuto, kukonza mafiriji owonetsera zitseko zagalasi ndikofunikiranso. Kudziwa momwe mungathetsere ndikusamalira mafiriji owonetsera awa kumatsimikizira kuti amakhala nthawi yayitali komanso kuti amagwira ntchito bwino.

 

Kusagwira bwino ntchito koziziritsa (chifukwa cha kuchepa kwa mafiriji, ma condenser coils akuda, ndi vuto la compressor)

Kuthetsa mavuto a firiji yoziziritsa yoyipa:

• Yang'anani kuchuluka kwa zinthu zoziziritsira mufiriji ndikuziwonjezeranso ngati pakufunika kutero.
• Tsukani ma coil a condenser nthawi zonse
• Funsani katswiri wa zaukadaulo kuti akukonzereni compressor

   

Kusakhazikika kwa kutentha (chifukwa cha thermostat yosagwira ntchito bwino, kutuluka kwa madzi mufiriji, kutseka zitseko molakwika)

Kuthetsa mavuto a firiji yowonetsera yokhala ndi kutentha kosakhazikika:

• Sinthani kapena sinthani thermostat
• Konzani kutayikira kulikonse kwa firiji
• Sinthani zitseko zowonongeka

 

Phokoso Lochuluka (chifukwa cha compressor yosakhazikika, mavuto a fan, phokoso la kayendedwe ka refrigerant)

Kuthetsa mavuto a firiji yowonetsera yokhala ndi phokoso lalikulu:

• Limbitsani compressor ngati yamasuka
• Tsukani kapena sinthani mafani omwe ali ndi vuto
• Konzani zinthu bwino kuti muchepetse kufalikira kwa phokoso

  

Kuundana kwa Chipale Chofewa Kwambiri (chifukwa cha ma coil a evaporator odetsedwa, refrigerant yambiri, kutentha kochepa)

Kuthetsa mavuto a firiji yokhala ndi chisanu chochuluka

• Tsukani nthawi zonse ma coil a evaporator
• Tulutsani firiji yochulukirapo ngati pakufunika
• Sinthani makonda a kutentha kuti musaundane ndi chisanu

  

Kuzizira kwa Galasi (chifukwa cha kusiyana kwa kutentha komwe kumayambitsa kuzizira kwa galasi, kutseka bwino)

 Kuthetsa mavuto a firiji yowonetsera zakumwa yokhala ndi galasi:

• Gwiritsani ntchito filimu yotenthetsera kapena waya kuti mupewe kuzizira
• Onetsetsani kuti chitseko cha kabati chatsekedwa bwino kuti muchepetse kulowa kwa chinyezi

 

Chisindikizo Chosasuntha cha Chitseko (chifukwa cha ukalamba, kusintha, kapena kuwonongeka kwa mzere wosindikizira)

 Kuthetsa mavuto a firiji yokhala ndi chitseko chomasuka:

• Yang'anani ndikusintha zisindikizo zakale kapena zopindika
• Pewani kukakamiza kwambiri pakhomo
• Lumikizanani ndi kampani yogulitsa zinthu zina pambuyo pogulitsa

  

Kulephera kugwira ntchito bwino kwa magetsi (chifukwa cha mababu oyaka, mavuto a switch, mavuto a circuit)

 Kuthetsa mavuto a kuwala kolakwika kwa firiji yowonetsera:

• Sinthani mababu oyaka mwachangu
• Konzani kapena kusintha ma switch olakwika
• Konzani mavuto aliwonse a dera
