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 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 hluav taws xob nrog compressed cua thiab cua txias nruab nrab, lub tub yees compressor yuav yog qhov tsis tshua muaj siab (tsawg kub) refrigerant nyob rau hauv lub tshav kub exchanger rau hauv lub compressor lub tog raj kheej, lub refrigerant chav yog compressed, lub siab thiab kub. Lub siab kub thiab txias txias vapor yog nias mus rau lub condenser, nyob rau hauv lub condenser, lub siab kub refrigerant chav thiab cov dej txias los yog cua nrog ib tug kuj tsis tshua muaj kub exchanged, lub tshav kub ntawm lub refrigerant yog muab tshem tawm los ntawm 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 while maintaining the same pressure, uas ua rau muaj ntau ntawm 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.
