Ngena kwifriji, eyenzelwe ngokukodwa ukugcina nokugcina iimpahla ezifrijini, idlala indima ebalulekileyo kwi-logistics yanamhlanje ye-cold chain. Nangona kunjalo, inkqubo yokuqalisa ibaluleke ngokulinganayo; ukuqonda kunye nokuqina kwamanyathelo ayo kuchaphazela ngokuthe ngqo ukusebenza kunye nobomi bezixhobo zokugcina izinto ezibandayo. Eli nqaku liza kuchaza inkqubo yokuqalisa yokugcina izinto ezibandayo ukunceda abafundi bayiqonde ngcono.
Okokuqala, umsebenzi wokulungiselela ngaphambi kokuba uqalise ukusebenza ubalulekile. Xa ufaka i-ifriji kunye nefriji yokuhamba ngaphakathi, kubalulekile ukuqinisekisa ukuba ubushushu kunye nokufuma kwindawo yokufakela zifanelekile, kwaye azikho kwiingcolisi kunye neegesi eziphazamisayo. Ngaphezu koko, zonke izinto kufuneka ziqhagamshelwe ngokwemizobo, kwaye ukutywinwa kweendonga zangaphakathi nezangaphandle kufuneka kujongwe ukuqinisekisa ukuba isiphumo sefriji ngaphakathi kwindawo yokugcina ebandayo asichaphazeleki zizinto zangaphandle.
Ziziphi iinkqubo ezisisiseko zokufaka iyunithi yokugcina izinto ezibandayo emva kokufakelwa?
Okulandelayo, ukufakwa kwezixhobo zombane kubaluleke ngokulinganayo. Iimoto, iiteyiphu zokufudumeza, iidisplay, iiswitshi, kunye nezinye izixhobo zombane kufuneka zifakwe ngokweemfuno, kunye nazo zonke iindlela zokhuseleko ezifunekayo ukuqinisekisa ukhuseleko lombane. Ngaxeshanye, izixhobo zokujikeleza ezifrijini, ezifanaisicinezeli segumbi elibandayo,i-condenser yegumbi, iivalvu zokwandisa, kunye neevalvu zokulawula ukuhamba kwamanzi, nazo kufuneka zifakelwe kwaye zilungiswe ngokwendlela yohlobo lwesixhobo kunye nendlela yokulawula. Ukuba ngumatshini omtsha, kufuneka kongezwe isixa esifanelekileyo sefriji entsha.
Emva kokufakela, isigaba sokulinganisa iiparameter siqala. Ngokusekelwe kwiimfuno zokwenyani zomthengi, iiparameter ezahlukeneyo, ezifana nexesha lokuphumla kunye namaxesha okuqalisa/ukuvala, ziyalinganiswa ukuqinisekisa ukuba indawo yokugcina ebandayo isebenza phantsi kweemeko zobushushu ezimiselweyo kunye nokufuma. Ngeli xesha, kusetyenziswa izixhobo ezithile ukulinganisa ubushushu kwiipayipi zomoya kunye neendawo zokugcina. Ngokusekelwe kumlinganiselo, ukusebenza kwefriji kuyaphuculwa, kwaye inkqubo yokungenisa umoya ijongiwe ukuba isebenza kakuhle na.
Uvavanyo lokusebenza luyinxalenye ebalulekileyo yokuqaliswa kokugcinwa kwento ebandayo. Ixesha lokusebenza limiselwe ukuba lide kancinci ukuze kuvavanywe ngokupheleleyo uzinzo lokusebenza kwento ebandayo. Ngeli xesha, ukusebenza kwecompressor kufuneka kujongwe ngononophelo, kujongwe ukuhamba kweoyile kunye nenqanaba layo, kwaye kuqinisekiswe ukubaiyunithi yokukhenkcisakwaye isiphumo sokupholisa se-evaporator siyahlangabezana neemfuno. Ukuba kukho naziphi na iingxaki ezifunyenweyo, kufuneka kwenziwe uhlengahlengiso ngokukhawuleza.
Ngaphambi kokusetyenziswa ngokusemthethweni, kufuneka uqaliso lokuqalisa. Qhagamshela izixhobo zokubeka esweni kwaye uphucule ngakumbi ukusebenza kwendawo yokugcina ebandayo ngokusekelwe kwidatha yokubeka esweni. Kwangaxeshanye, cwangcisa imizobo, amaxwebhu, kunye nedatha evela kwinkqubo yokubeka esweni, kwaye ugcwalise ingxelo efanelekileyo yokubeka esweni ukuze ubhekisele kuyo kwixesha elizayo kwaye uyigcine.
Ukugcinwa kwemihla ngemihla kwendawo yokugcina izinto ezibandayo kubaluleke ngokulinganayo. Ngexesha lokusetyenziswa, inxalenye nganye kufuneka igcinwe rhoqo ukuqinisekisa ukuba ukusebenza kwayo akuchaphazeleki. Ngaphezu koko, isiphumo sokutywinwa kunye nokuqandisa kwendawo yokugcina izinto ezibandayo kufuneka sihlolwe rhoqo, kwaye naziphi na iingxaki kufuneka zichongwe kwaye zisonjululwe ngokukhawuleza.
Ngamafutshane, ukugunyaziswa kokugcinwa kwezixhobo ezibandayo yinkqubo enzima kodwa efunekayo. Ukuqonda kunye nokuqina kwamanyathelo ayo kuchaphazela ngokuthe ngqo isiphumo sokusebenza kunye nobomi bezixhobo zokugcina izixhobo ezibandayo. Ke ngoko, ngexesha lokugunyaziswa kwezixhobo, kubalulekile ukulandela ngokungqongqo iinkcukacha kunye nokuqinisekisa ukuba inyathelo ngalinye lenziwa ngokufanelekileyo. Kungale ndlela kuphela apho ukusebenza okuzinzileyo kwezixhobo zokugcina izinto ezibandayo kunokuqinisekiswa, kubonelela ngenkxaso enamandla kwizixhobo zokugcina izinto ezibandayo.
