Lub freezer ceev yog tsim los ntawm tsib ntu hauv series: compressor, condenser, evaporator, lim qhuav, thiab expansion throttle valve.Tus nqi ntawm cov tub yees raug txhaj rau hauv nws, thiab cov khoom siv hluav taws xob tswj kev ua haujlwm ntawm lub tshuab compressor raws li qhov xav tau ntawm ib puag ncig kom ua tiav cov tub yees thiab cov cua sov hloov.lub hom phiaj ntawm.
compressor
Lub tshuab hluav taws xob uas tau tsav los ua kom cov pa roj tsawg kom siab siab.Lub freezer ceev yog lub plawv ntawm lub tub yees system.Nws nqus cov pa uas tsis muaj qhov kub thiab txias txias los ntawm cov yeeb nkab suction, tsav lub piston kom compress nws los ntawm kev ua haujlwm ntawm lub cev muaj zog, thiab tso tawm cov pa kub thiab cov cua kub siab rau cov yeeb nkab kom muab lub zog rau lub tub yees. lub voj voog.Nyob rau hauv txoj kev no, lub voj voog tub yees ntawm compression → condensation → nthuav dav → evaporation (heat absorption) yog paub.
condenser
Qhov kub thiab txias txias txias vapor tawm los ntawm compressor yog condensed rau hauv cov kua refrigerant los ntawm tshav kub dissipation, thiab lub tshav kub absorbed los ntawm lub refrigerant los ntawm lub evaporator yog absorbed los ntawm nruab nrab (atmosphere) nyob ib ncig ntawm lub condenser.
Evaporator
Cov kua refrigerant hloov mus rau lub xeev gaseous ntawm no.
lim kom qhuav
Nyob rau hauv lub tub yees system, lub luag haujlwm ntawm cov lim qhuav yog nqus cov dej noo hauv lub tub yees, thaiv cov impurities hauv lub cev kom lawv tsis tuaj yeem hla, thiab tiv thaiv cov dej khov thiab qias neeg hauv lub tub yees system pipeline.Txij li thaum lub capillary (los yog expansion valve) yog qhov yooj yim tshaj plaws thaiv ib feem ntawm lub system, lub lim qhuav feem ntau yog ntsia nruab nrab ntawm lub condenser thiab lub capillary (los yog expansion valve).
Expansion throttle valve
Throttling thiab depressurizing lub siab-siab kua refrigerant los ntawm cov kua cia tshuab ziab khaub ncaws, kho thiab tswj tus nqi ntawm cov kua refrigerant nkag mus rau hauv lub evaporator, thiaj li hloov mus rau qhov hloov ntawm lub tub yees load, thiab nyob rau tib lub sij hawm tiv thaiv cov kua rauj tshwm sim ntawm lub compressor thiab vapor ntawm qhov hluav taws xob ntawm lub evaporator Tsis zoo li overheating.
