Cov tub yees yog tsim los ntawm compressor, condenser, evaporator, ziab lim thiab expansion throttle valve nyob rau hauv series, nyob rau hauv uas ib tug tsim nyog npaum li cas ntawm cov tub yees raug txhaj, thiab cov hluav taws xob cov cuab yeej tswj lub compressor ua hauj lwm raws li ib puag ncig xav kom ua tiav lub hom phiaj ntawm tub yees thiab cua sov. hloov [4].
compressor
Lub tshuab ua kua dej uas nqa cov pa roj tsawg kom siab siab. Nws yog lub plawv ntawm lub tub yees system. Nws nqus cov pa roj tub yees nrog qhov kub thiab txias los ntawm cov yeeb nkab nqus, tsav lub piston kom compress nws los ntawm kev ua haujlwm ntawm lub cev muaj zog, thiab tom qab ntawd tso cov roj tso rau hauv tub yees nrog qhov kub thiab txias rau cov yeeb nkab kom muab lub zog rau lub tub yees, yog li Raws li kev paub txog lub tub yees lub voj voog ntawm compression → condensation → expansion → evaporation (heat absorption).
condenser
Lub high-temperature thiab high-pressure refrigerant vapor tawm ntawm lub compressor yog condensed rau hauv kua refrigerant los ntawm tshav kub dissipation. Lub tshav kub absorbed los ntawm cov tub yees los ntawm lub evaporator yog absorbed los ntawm nruab nrab (atmosphere) nyob ib ncig ntawm lub condenser.
evaporator
Ntawm no cov kua refrigerant hloov mus rau hauv ib tug roj.
Qhuav lim
Nyob rau hauv lub tub yees system, lub luag hauj lwm ntawm lub tshuab ziab khaub ncaws yog absorbed noo noo nyob rau hauv lub tub yees system, thaiv cov impurities nyob rau hauv lub system kom tsis txhob dhau mus, thiab tiv thaiv lub tub yees system pipeline los ntawm dej khov thiab av blockage. Txij li thaum lub raj capillary (los yog expansion valve) yog qhov yooj yim tshaj plaws thaiv ib feem ntawm lub cev, lub tshuab ziab khaub ncaws feem ntau yog ntsia nruab nrab ntawm lub condenser thiab lub raj capillary (los yog expansion valve).
expansion ntaus ntawv
Lub siab-siab kua refrigerant los ntawm cov kua cia tshuab yog throttled thiab depressurized, thiab cov kua refrigerant kom muaj nuj nqis nkag mus rau hauv lub evaporator yog kho thiab tswj kom hloov mus rau qhov hloov ntawm lub tub yees load. Nyob rau tib lub sijhawm, qhov tshwm sim ua kua rauj ntawm lub compressor thiab qhov txawv txav ntawm cov pa ntawm qhov hluav taws xob ntawm lub evaporator tuaj yeem tiv thaiv.
