Njengenxalenye ebalulekileyo yenkqubo yokugcina ifriji ebandayo, i-air cooler iqala ukubanda kumphezulu we-evaporator xa i-air cooler isebenza kubushushu obungaphantsi kwe-0℃ nangaphantsi kwe-air dew point. Njengoko ixesha lokusebenza lisanda, umaleko we-frost uya kuba mkhulu ngakumbi nangakumbi. Izizathu zokuqandisa i-air cooler (i-evaporator)
1. Ukungabikho komoya owaneleyo, kubandakanya ukuvaleka kombhobho womoya obuyayo, ukuvaleka kwesihluzo, ukuvaleka komsantsa wephini, ukungasebenzi kakuhle kwefeni okanye isantya esiphantsi, njl.njl., okubangela ukutshintshiselana kobushushu okwaneleyo, uxinzelelo oluphantsi lokuphuma komphunga, kunye nobushushu obuphantsi bokuphuma komphunga;
2. Iingxaki ngesixhobo sokutshintsha ubushushu ngokwaso. Sisetyenziswa rhoqo isixhobo sokutshintsha ubushushu, kwaye ukusebenza kotshintsho lobushushu kwehla, nto leyo enciphisa uxinzelelo lokuphuma komphunga;
3. Ubushushu bangaphandle buphantsi kakhulu. Ifriji eqhelekileyo ayiweli ngaphantsi kwama-20℃, ifriji kwindawo enobushushu obuphantsi iya kubangela ukutshintshiselana kobushushu okwaneleyo kunye noxinzelelo oluphantsi lokuphuma komphunga;
4. Ivalvu yokwandisa ivalekile okanye inkqubo ye-pulse motor elawula ukuvulwa kwayo yonakele. Kwinkqubo yokusebenza ixesha elide, ezinye izinto ezimdaka ziya kuyivala i-expansion valve port kwaye zenze ingakwazi ukusebenza ngokuqhelekileyo, nto leyo enciphisa ukuhamba kwe-refrigerant kwaye yehlise uxinzelelo lokuphuma komphunga. Ulawulo olungaqhelekanga lokuvula luya kubangela ukwehla kokuhamba kwayo kunye noxinzelelo;
5. Ukugoba kwesibini, ukugoba imibhobho okanye ukuvaleka kwenkunkuma ngaphakathi kwi-evaporator kubangela ukugoba kwesibini, okubangela ukuba uxinzelelo kunye nobushushu behle kwindawo emva kokugoba kwesibini;
6. Ukuhambelana kakubi kwenkqubo. Ukuchaneka, i-evaporator incinci okanye imeko yokusebenza kwe-compressor iphezulu kakhulu. Kwimeko enjalo, nokuba ukusebenza kwe-evaporator kusetyenziswe ngokupheleleyo, imeko yokusebenza kwe-compressor ephezulu iya kubangela uxinzelelo oluphantsi lokufunxa kunye nokwehla kobushushu bokufuma;
7. Ukungabikho kwe-refrigerant, uxinzelelo oluphantsi lokuphuma komphunga kunye nobushushu obuphantsi bokuphuma komphunga;
8. Umswakama oqhelekileyo kwindawo yokugcina izinto uphezulu, okanye i-evaporator ifakwe kwindawo engalunganga okanye ucango lokugcina izinto ezibandayo luvulwa kwaye luvalwe rhoqo;
9. Ukunyibilikisa okungaphelelanga. Ngenxa yexesha elaneleyo lokunyibilikisa kunye nendawo engafanelekanga yeprobe yokubuyisela ukunyibilikisa, i-evaporator iqaliswa xa inganyibiliki ngokupheleleyo. Emva kwemijikelo emininzi, umaleko weqabaka wendawo ye-evaporator uyaqina ube ngumkhenkce kwaye uqokeleleke kwaye ube mkhulu.
Iindlela zokunyibilikisa i-frost yokugcina ubushushu 1. Ukunyibilikisa umoya oshushu – kufanelekile ukunyibilikisa imibhobho yeendawo zokugcina ubushushu obukhulu, obuphakathi nobuncinci: Vumela ngokuthe ngqo i-ejenti yokunyibilikisa igesi eshushu enobushushu obuphezulu ingene kwi-evaporator ngaphandle kokuthintela, kwaye ubushushu be-evaporator buyanyuka, nto leyo ebangela ukuba umaleko weqhwa kunye ne-pipe joint zinyibilike okanye ziphume. Ukunyibilikisa umoya oshushu kungabizi kwaye kuthembekile, kulula ukuyigcina nokuyilawula, kwaye ubunzima bayo botyalo-mali kunye nokwakha abubukhulu. 2. Ukunyibilikisa i-water spray – esetyenziswa kakhulu ekunyibilikiseni ii-air coolers ezinkulu neziphakathi: Sebenzisa amanzi obushushu obuqhelekileyo rhoqo ukutshiza nokupholisa i-evaporator ukuze inyibilikise umaleko weqhwa. Nangona ukunyibilikisa i-water spray kunefuthe elihle lokunyibilikisa, ifanelekile ngakumbi kwii-air coolers kwaye kunzima ukuyisebenzisa kwii-coils ezikhupha ubushushu. Ungasebenzisa isisombululo esinobushushu obuphezulu be-freeze point, njenge-5% ukuya kwi-8% ye-brine exineneyo, ukutshiza i-evaporator ukuthintela ukwakheka kweqhwa. 3. Ukunyibilikisa umbane – iityhubhu zokufudumeza zombane zisetyenziswa kakhulu kwii-air coolers eziphakathi nezincinci: Iintambo zokufudumeza zombane zisetyenziswa kakhulu ekunyibilikiseni umbane kwiipayipi ze-aluminium kwiindawo zokugcina ezibandayo eziphakathi nezincinci. Kulula kwaye kulula ukuzisebenzisa kwii-air coolers; kodwa kwiindawo zokugcina ezibandayo zeepayipi ze-aluminium, ubunzima bokwakha bokufaka iintambo zokufudumeza zombane kwiiphini ze-aluminium abuncinci, kwaye izinga lokungaphumeleli kwixesha elizayo nalo liphezulu, ukugcinwa nokulawulwa kunzima, ukusebenza kakuhle kwezoqoqosho akukuhle, kwaye ukhuseleko luphantsi. 4. Ukunyibilikisa ngesandla ngesandla – ukunyibilikisa umbhobho omncinci wokugcina ubanda kuyasebenza: Ukunyibilikisa ngesandla iipayipi zokugcina ubanda kubiza kakhulu kwaye yindlela yokuqala yokunyibilikisa. Akukho ngqiqweni ukusebenzisa ukunyibilikisa ngesandla kwiindawo zokugcina ubanda ezinkulu. Kunzima ukusebenza intloko ithe tye, kwaye amandla omzimba asetyenziswa ngokukhawuleza. Kuyingozi empilweni ukuhlala kwindawo yokugcina impahla ixesha elide kakhulu. Akulula ukunyibilikisa ngokupheleleyo, okunokubangela ukuba i-evaporator yonakale, kwaye kunokonakalisa i-evaporator kwaye kubangele ingozi yokuvuza kwefriji.
