My question is. How can an expansion feed into a header and still feed may be twenty or more tubes equally.
Experimental Research and CFD Simulation on
Microchannel Evaporator Header to Improve Heat
"Obviously, the single inlet header concentratedly distributes refrigerant into middle portion of microchannel
coil; the dual inlet header significantly improves the refrigerant distribution uniformity inside inlet coil header; and
the distributor inlet header performs the most uniformed refrigerant distribution."
