I-pieliction ye-pipelic ye-piholi ye-piholi yePiidile kunye nokukhethwa kwe-ping

1. Ukwaziswa kweeyunithi zefriji zefriji

Icandelo elifanayo libhekisa kwiyunithi yefriji edibanisa ngaphezulu kweengcinezelo ezimbini kwi-rack enye kwaye isebenzela amaqela amaninzi. Iingcingo zinoxinzelelo oluqhelekileyo loxinzelelo kunye noxinzelelo lwezinto zokuzimela, kunye neyunithi efanayo yokuhlengahlengisa ngokuzenzekelayo amandla ngokomthwalo wenkqubo. Inokuqaphela ukunxiba i-compressor, kwaye iyunithi yefriji ithatha indawo encinci, kwaye kulula ukufezekisa ulawulo oluphakathi kunye nolawulo olukude.

Iseti efanayo yeyunithi inokuqulunqwa ngohlobo olufanayo lweengcinezelo, okanye iintlobo ezahlukeneyo zeembambano. It can be composed of the same type of compressor (such as piston machine), or it can be composed of different types of compressors (such as piston machine + screw machine); Ingalayisha ubushushu obukhulu okanye amaqondo obushushu ahlukeneyo okuphuma. Ubushushu; Inokuba yinkqubo yenqanaba elinye okanye inkqubo yenqanaba ezimbini; Inokuba yinkqubo yomjikelo omnye okanye inkqubo ye-casasade, njl.

Iiyunithi ze-compreslel ze-comprevel compressor zingcono dibanisa umthwalo wokupholisa opholileyo wenkqubo yokwenziwa kwefriji. Ngokuhlengahlengisa ukuqala nokuma kwe-compressor kuyo yonke inkqubo, imeko ye-"ihashe elikhulu kunye nebhokisi encinci" iyathintelwa. Umzekelo, xa isicelo sokupholisa sifunekile siphantsi ebusika, i-compressor ivuliwe, kwaye ehlotyeni, imfuno yokupholisa inkulu, kwaye i-compressor iguqukele ngaphezulu. Ingcinezelo yokunikezelwa kwecandelo le-compressor ligcinwa lihlala lihleli, nto leyo ephucula kakhulu impumelelo yenkqubo. Uvavanyo lokuthelekisa iyunithi enye kunye neyunithi efanayo yenziwa kwinkqubo enye, kwaye inkqubo yeyunithi efanayo inokugcina amandla nge-18%.

Zonke iingcingo zoxinzelelo, ii-themba kunye nabakhupheli zinokujongwa kwibhokisi yombane wombane, kwaye abalawuli beekhompyuter banokusetyenziswa ukwandisa ukusebenza kwenkqubo. Ngokusisiseko, ngokugqibeleleyo ukusebenza okungapheliyo kwaye umsebenzi ode kuya kufezekiswa.

I-2. I-Pipelililine
I-Pipeliline yePidileline: Kwinkqubo yokuqhutywa kwe-freon, i-compressor ijikeleza ioyile kwiNkqubo yokuBuya kweNdawo, i-Pipeline yoMoya) kufuneka ibe nethambeka le-oyile, kufuneka libe nethambeka elithile kwi-0.5%.

Ukukhetha ububanzi be-PIM Ukuba ixabiso likhulu kakhulu, nangona ilahleko yokuchasana nombhobho inokuncitshiswa, iya kubangela ukwanda kweendleko zokuqala zotyalo-mali, kwaye kwangaxeshanye, iya kubangela ukungabuyisi kwi-oyile ye-oyile kwi-oyile ye-oyile.

Umgaqo-siseko wokukhetha i-Deametter Kwindlela yokubuya ye-air, i-velocity ye-velorant ye-pipeling the phengo yi-7-10m / s, i-valocity ye-velorant yefriji enyukayo yi-15 ~ 18m / s.

Uhlobo lohlobo lwesebe: Kukho izihloko zokuhambisa amanzi kwaye zibuyisele iintloko zomoya kwiyunithi yokuthengisa i-pharal, kwaye kukho isebe lokubonelela ngolwelo kwi-syds, kwaye enye ibuyela kwisebe lenkqubo yokubonelela ngolwelo libizwa ngokuba luhlobo lwesebe. Isibini ngasinye samasebe, oko kukuthi, isebe lokubonelela ngolwelo kunye nesebe elinokubuya kwisebe elihambelana noko, linokuba ne-Evaporator (isebe le-1) okanye iqela labakhukulisekiweyo (isebe n). Xa liqela labakhukulisekiweyo, ngokufuthi iqela labakhukulisekiweyo liqala kwaye liyekile ngaxeshanye.

I-Evaporator iphezulu kune-compressor:
Ukuba i-evaporator ingaphezulu kwe-compressor, okoko nje umgca wokubuya unethambeka elithile kwaye ukhetha ububanzi bombhobho ofanelekileyo, inkqubo inokuqinisekisa ukubuya kweoyile. However, if the height difference between the evaporator and the compressor is too large, the liquid refrigerant in the liquid supply pipeline will generate flash steam before reaching the throttling mechanism. ye-supercooling.

I-Evaporator iphantsi kune-compressor:
Ukuba i-Evaporator iphantsi kune-compressor, i-frientrantrants kwi-pipelip yokubonelela ngolwelo ayizukuvelisa i-flash steam ngenxa yomahluko wenkqubo yokuqhekeka, kodwa xa ibuyiselwe ngokupheleleyo inkqubo. Ingxaki yeoyile, ngeli xesha, imbuyekezo yeoyile kufuneka iyilwe kwaye ifakwe kwicandelo lokunyuka ngesebe ngalinye lokubuya.
