Thaum tshav kub kub Exchange Efficiency: Kev tsim cov evaporator ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub tub yees. Nws thaj chaw nto, piping layout, thiab cov ntaub ntawv yog qhov tseem ceeb. Piv txwv li, cov evaporators siv cov raj tooj liab lossis txhuas fins tuaj yeem txhim kho cov cua sov kom zoo dua vim tias tooj liab muaj cov thermal conductivity siab txog 401 W / (m·K), thaum txhuas muaj thermal conductivity ntawm 237 W / (m·K), ob qho tib si deb dua li cov hlau zoo tib yam. Tsis tas li ntawd, qhov sib nrug ntawm qhov fin (feem ntau 1.5-}3 hli) thiab cov yeeb nkab txoj kab uas hla (feem ntau 6-}12 hli) ntawm cov evaporator yuav tsum tau kho kom zoo raws li daim ntawv thov scenario kom sib npaug airflow kuj thiab tshav kub exchanger cheeb tsam. Hauv cov chaw txias txias loj, cov evaporators tuaj yeem siv cov yeeb nkab-hom tsim nrog thaj tsam ntawm ntau pua square metres los tiv thaiv qhov xav tau ntawm cov cua txias siab; Thaum nyob rau hauv tsev cua txias, evaporators yog compact, nrog ib tug nto cheeb tsam feem ntau ntawm 1 thiab 5 square meters.
Lub evaporator yog ib qho ntawm cov khoom tseem ceeb ntawm lub tub yees system. Nws txoj haujlwm yog nqus cov cua sov kom ua tiav cov txheej txheem "evaporative heat absorption" nyob rau hauv lub voj voog tub yees, yog li txo qis qhov kub thiab txias hauv ib qho chaw. Los ntawm kev pom kev, lub evaporator tau ntim nrog qhov qis -kub, qis- siab ua kua refrigerant. Thaum cov refrigerant ntws los ntawm cov evaporator cov kav dej, nws pauv cov cua sov nrog cov huab cua ib puag ncig lossis nruab nrab. Vim tias qhov kub ntawm cov kua refrigerant qis dua li qhov kub thiab txias, nws sai absorbs cua sov thiab evaporates rau hauv lub xeev gaseous; txheej txheem no hu ua "boiling evaporation." Los ntawm kev nqus cov cua kub tsis tu ncua, cov evaporator txo qis qhov kub ntawm qhov nruab nrab ib puag ncig, piv txwv li, los ntawm kev txo cov cua kub hauv tsev hauv lub tshuab cua txias lossis tswj qhov kub qis - ib puag ncig hauv cov khoom siv tub yees.
