Thaum superheat qhia tias cov tub yees ntau npaum li cas hauv cov evaporator (high superheat qhia tias tsis txaus, qis superheat qhia ntau dhau), subcooling qhia tias ntau npaum li cas cov tub yees nyob rau hauv lub condenser. Subcooling ntawm cov tshuab uas siv lub tshuab nqus tsev thermostatic expansion valve (TXV) yuav tsum yog kwv yees li 10F txog 18F.
superheat thiab subcooling ua haujlwm li cas?
Superheat tshwm sim thaum lub vapor yog rhuab saum nws lub boiling point. … Condensation yog thaum lub vapor poob kub thiab hloov mus rau hauv cov kua, tab sis subcooling yog thaum cov kua txias txias hauv qab qhov kub uas nws hloov mus ua kua.
