Ziziphi iimfuno zokusebenza eziqhelekileyo zeefriji?

Ukuba i-chiller inokusebenza ngokuqhelekileyo kwaye ikhuselekile, ifriji iyimfuneko. Yindlela yokusebenza ejikelezayo kwi-chiller system yefriji yokufikelela kwifriji, kwaye ikwabizwa ngokuba yi-refrigeration medium medium okanye ifriji. Ngoko ke, zeziphi iimfuno eziqhelekileyo zokusebenza kwesikhenkcisi kwizikhenkcezisi zemijikelo eyahlukeneyo yesikhenkcisi?

1. Iimpawu zeThermodynamic [plating chiller]

1. Kufuneka ibe noxinzelelo oluphakathi olugcwele umphunga. Uxinzelelo oluphuma emoyeni kufuneka lungabi ngaphantsi kunoxinzelelo lwe-atmospheri ukunqanda ukuvuza komoya kwisixokelelwano (thatha i-screw chiller/i-air-cooled chiller/i-chiller epholiswe ngamanzi njengomzekelo); Uxinzelelo lokunciphisa akufanele lube phezulu kakhulu, ngaphandle koko iimfuno zokuchasana noxinzelelo lwenkqubo ziya kuchaphazeleka. Ukwandisa, kwaye kuya kwandisa ukusetyenziswa kwamandla; ukongeza, umlinganiselo woxinzelelo loxinzelelo kuxinzelelo oluphuma ngumphunga akufanele ube phezulu kakhulu, kungenjalo kuya kubangela ukunyuka kweqondo lobushushu lecompressor lechiller.

2. Kufuneka ibe nobushushu obuphezulu obuphezulu (ngaphezu kobushushu be-ambient), ukwenzela ukuba i-liquefied kwiqondo lokushisa eliqhelekileyo okanye ukushisa okuqhelekileyo okuphantsi, kunye nokulahlekelwa kwe-throttling kuya kuncitshiswa.

3. Kufuneka ibe nobushushu obuphantsi bokuqina. Oku kuthintela isikhenkcezisi ekubeni sikhe sibe ngumkhenkce kubushushu obuphuphumayo.

4. Kufuneka ibe ne-thermal conductivity ephezulu. Oku kunokonyusa i-coefficient yokuhambisa ubushushu kwi-chiller (thatha i-screw chiller / i-air-cooled chiller / i-water-cooled chiller njengomzekelo), ukunciphisa indawo yokudlulisa ubushushu, kunye nokunciphisa iindleko zokuvelisa kunye nokusebenza.

5. Kufuneka kubekho isalathisi esincinci se-adiabatic. Oku kunokwenza inkqubo yoxinzelelo idle amandla amancinci, kwaye ubushushu bokukhutshwa kwecompressor abuyi kuba phezulu kakhulu.

6. Umthamo wobushushu obuthile bolwelo lwefriji buncinci. Oku kunokunciphisa ukulahleka kwenkqubo ye-throttling.

2. Ukusebenza komzimba kunye neekhemikhali [i-air-cooled chiller]

1. Kufuneka ibe noxinano oluncinci kunye ne-viscosity, enokunciphisa ilahleko yokumelana nokuhamba kwefriji kwiyunithi yefriji yeyunithi (thatha i-screw chiller / i-air-cooled chiller / i-water-cooled chiller njengomzekelo).

2. Kufunwa ukuba kungabi nokutsha, kuqhume, kungabi netyhefu, kwaye kungabi lula ukubola phantsi kobushushu obuphezulu, kwaye akukho lula ukutshabalalisa iindawo zetsimbi ze-chiller.
