Tshem tawm cov kua kab Kub Kub los ntawm Cov Kua Dej Saturation Kub thiab koj tau txais Subcooling ntawm 15. "Feem ntau" ntawm TXV systems the Superheat yuav nyob nruab nrab ntawm 8 txog 28 degreesnrog Qhov ntsuas kub ntawm 10 txog 15 degrees. Subcool ntau yam ntawm TXV systems yuav muaj li ntawm 8 txog 20.
Koj suav superheat li cas?
ntsuas qhov ntsuas qhov ntsuas kub thiab qhov nqus siab ntawm qhov nqus sab qhov kev pabcuam valve. Xyuas kom lub ntsuas kub ntsuas yog insulated los ntawm ib qho kev cuam tshuam sab nraud. Hloov lub ntsuas qhov siab mus rau qhov kub thiab txias thiab rho tawm qhov kub ntawm qhov nqus kab kub. Nov yog tag nrho superheat.
Yuav ua li cas yog tus qauv rau subcooling?
Xaiv cov subcooling raws li hauv qab no: subcooling=CT – T. Rau cov tub yees sib xyaw siv cov kua dej saturated (npuas) kub raws li qhov ntsuas kub. Subcooling feem ntau yuav tsis tshwm sim hauv lub condenser tshwj tsis yog cov kua rov qab rau hauv lub condenser.
Dab tsi yog qhov zoo tshaj plaws superheat thiab subcooling?
Feem ntau cov cua sov thiab cua txias yuav tsum ua haujlwm ntawm superheat ntawm 10F ntawm lub evaporatorthiab ntawm 20F txog 25F ntawm lub compressor. Yog tias koj lub HVAC system muaj qhov ntsuas kub ntawm qhov ntsuas kub (TXV), lub subcooling yuav tsum nyob nruab nrab ntawm 10F thiab 18F.
Lub hom phiaj zoo superheat yog dab tsi?
Qhov tsawg kawg nkaus pom zoo lub hom phiaj superheat rau feem ntau cov kab kos yog nruab nrab ntawm 4F txog 5F rau qhov chaw ib puag ncig uas tsis muaj qhov muag ntub hauv tsev thiab qhov muag sab nraum zoov qhuav.
