Tub yees chav tsev condenser evaporator ua hauj lwm hauv paus ntsiab lus piav qhia

Lub evaporator yog ib qho ntawm plaub feem ntawm lub tub yees chav tsev, uas yog lub tshav kub exchanger. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tub yees yog siv txoj kev evaporation kom evaporate lub tub yees (boiling), nqus cov cua sov ntawm lub tub yees, thiab ua tiav lub hom phiaj ntawm lub tub yees. Cov evaporator yog cov khoom siv txias tso tawm ntawm chav tsev tub yees. Cov evaporator feem ntau yog tsim los ntawm cov cua sov chamber thiab cov evaporation chamber. Cov cua sov chamber feem ntau muab cov cua sov uas xav tau rau cov evaporation ntawm cov kua los txhawb cov boiling thiab vaporization ntawm cov kua. Thaum lub evaporation chamber nyob rau hauv ib qho chaw loj dua tom qab gasification, cov kua yuav raug cais tawm ntawm lub chav los ntawm nws tus kheej condensation los yog lub luag hauj lwm ntawm lub defroster.

Cov evaporator yog cov khoom siv hluav taws xob sib hloov uas tso cai rau cov cua kub uas tsis tshua muaj cov kua refrigerant los pauv cov cua sov nrog qhov nruab nrab uas yuav tsum tau txias.

Cov evaporators yog: tag nrho cov kua evaporator, qhuav evaporator, circulating evaporator, tshuaj tsuag evaporator.

Vim yog lub luag haujlwm ntawm lub tub yees sib txawv, hom evaporator siv kuj sib txawv, thiab tom qab ntawd feem ntau siv tag nrho cov kua evaporator thiab cov evaporator qhuav ua piv txwv, qhia koj txog lawv lub luag haujlwm.

1. Cov kua evaporator tag nrho: Nws txoj haujlwm yog tias thaum lub tub yees tau dhau los ntawm lub tshav kub hloov pauv, cov tub yees yuav ua rau lub raj xa hluav taws xob tag nrho, thiab nws yuav evaporate sab nraum lub tshav kub pauv raj tom qab nqus cua sov. Muaj ntau tus pin-puab qhov nyob rau sab nrauv ntawm lub raj xa hluav taws xob, thiab cov hlua khi rau ntawm lub raj, uas yuav ntxiv dag zog rau qhov kub ntawm sab nraud ntawm lub raj thiab cov cua kub hloov mus rau hauv lub raj. Qhov kom zoo dua ntawm cov kua evaporator tag nrho yog tias cov cua sov hloov coefficient siab dua li ntawm cov evaporator qhuav. Nws qhov tsis zoo yog tias tus nqi ntawm cov tub yees yog qhov loj, tus nqi siab, lub tog raj kheej evaporator yuav khaws cov roj, thiab yuav tsum muaj kev ntsuas roj rov qab.

2. Qhuav evaporator: Nws lub luag haujlwm yog tias thaum cov tub yees hla hauv lub tshav kub hloov pauv, cov tub yees yuav khiav tawm sab nraud ntawm lub raj xa hluav taws xob, thiab cov khoom siv hluav taws xob hloov hluav taws xob ntawm cov khoom siv hluav taws xob no kuj tsawg. Nws qhov zoo dua yog tias nws yooj yim rov qab cov roj thiab tswj tau yooj yim, thiab qhov ntim ntawm cov tub yees yog li 1/2 txog 1/3 ntawm qhov ntim ntawm cov kua dej puv, uas yog kev lag luam ntau dua.
