Metering device?
Basically this is the system I'm working on atm, it's my little project.
I'll be using a 3/4hp LPB R404A compressor, with a co-axial water cooled condenser. The refrigerant pump with be a bronze 1/3hp gear pump, and the refrigerant will be R410A.
My question is: What type of metering device would give the greatest performance in a system similar to this? I'm not sure if a tev would work. I was thinking about using cap tube with a solenoid valve on the liquid line and a liquid level sensor in the liquid separator. Simply I have to always maintain the column of liquid on the pump inlet to avoid cavitation.
Any thoughts?
