Lub tshuab tub yees ntawm lub tub yees tshuab yog nyob rau hauv compression tub yees, uas yog tsim los ntawm plaub yam yooj yim xws li lub tub yees compressor, condenser, tshav kub exchanger, thiab expansion valve. Lawv txuas nrog hauv lem nrog cov kav dej los tsim ib lub kaw lus kaw, cov tub yees nyob rau hauv lub kaw lus txuas ntxiv mus thiab ntws, lub xeev hloov pauv thiab hloov pauv nrog cov cua compressed thiab cua txias nruab nrab, lub tub yees compressor yuav yog qhov tsis tshua muaj siab (tsawg kub) refrigerant hauv lub tshav kub exchanger rau hauv lub compressor lub tog raj kheej, lub refrigerant chav yog compressed, lub siab thiab kub nce nyob rau tib lub sij hawm; Lub siab-siab thiab kub-kub refrigerant vapor yog nias mus rau lub condenser, nyob rau hauv lub condenser, lub siab dua kub refrigerant chav thiab cov dej txias los yog cua nrog ib tug kuj tsis tshua muaj kub yog kub exchanged, lub tshav kub ntawm lub refrigerant yog tshem tawm los ntawm lub dej los yog cua thiab condensed, thiab lub refrigerant vapor ua kua. Qhov no ntawm cov kua yog ces thauj mus rau lub expansion valve, los ntawm uas nws yog throttled mus rau hauv ib tug tsawg-kub thiab tsawg-siab kua thiab nkag mus rau lub tshav kub exchanger; Nyob rau hauv lub tshav kub exchanger, lub low-temperature, low-pressure refrigerant absorbs the heat of high-temperature, high-pressure compressed air, and the temperature of compressed air is forcedly reduces thaum tswj tib lub siab, ua rau muaj ntau yam. supersaturated dej vapor. Lub refrigerant vapor nyob rau hauv lub tshav kub exchanger yog nqus los ntawm lub compressor, thiaj li hais tias cov tub yees mus los ntawm plaub txheej txheem ntawm compression, condensation, throttling thiab evaporation nyob rau hauv lub system, yog li ua tiav ib lub voj voog.
