But not quite for the reason stated:
" With a low charge, you only get a dribble of liquid into the evap,
which is
at too low a temp because of the too-low suction pressure "

The evaporator temperature is a result of the vaporization of the
refrigerant, not "too-low suction pressure".

It's a result of the vaporization under too-low of a suction pressure.
More to the point, it's a result of the coil's skin temperature dropping below
freezing, because of the vaporization under too low of a suction pressure.

This is Turtle.

What you spoke about here has been on my mine for YEARS and ties into the
evaperator coils on hvac system up at 38 psi to 42 psi in Louisiana and other
lower humidity areas at 50 psi. Do you know any places where a fellow could read
up on this freezing of the coil at lower temp and pressures of the evaperator
coil.
