Calculating percentage of liquid in a coil?
Calculating percentage of liquid in a coil?
(OP)
I'm currently designing a unit that's performance is very sensitive to the charge of refrigerant. I have a spread sheet that calculates the charge of refrigerant needed based on operating conditions, however the one part that remains a dark art is the percentage of liquid in the evaporator and condenser coils. This seems to have a major effect on the total charge of the unit.
Does anyone know a method of calculating the percentage of liquid refrigerant in the coils?
