Lub hauv paus ntsiab lus ua haujlwm ntawm evaporator yog siv txoj kev evaporation los ua kom sov cov tshuaj thiab vaporize thiab tshem tawm qee cov kuab tshuaj los txhim kho cov tshuaj concentration. Cov evaporator yog cov khoom siv cua txias hauv lub tub yees. Lub refrigerant evaporates nyob rau hauv lub evaporator thiab absorbs lub tshav kub ntawm qhov nruab nrab kub kub qhov nruab nrab kom ua tiav lub hom phiaj ntawm lub tub yees. Cov evaporators muaj xws li: tag nrho cov kua evaporator, qhuav evaporator, circulating evaporator thiab tshuaj tsuag evaporator. Cov evaporator feem ntau yog tsim los ntawm cov cua sov chamber thiab cov evaporation chamber. Cov cua sov chamber muab cov cua sov uas yuav tsum tau ua rau evaporation ntawm cov kua, thiab txhawb cov boiling thiab vaporization ntawm cov kua. Tom qab vaporization, cov kua mus txog lub evaporation chamber nyob rau hauv ib qho chaw loj. Cov kua dej no tuaj yeem raug cais tawm ntawm chav dej los ntawm lawv tus kheej condensation lossis lub luag haujlwm ntawm demister.
