This is information I found on it.
A POA Valve is a pilot operated absolute valve. It is in the suction line. It keeps the evap pressure at about 30 psi so it is cold , but not cold enough to freeze up and restrict air flow (ice).
If you had a GM car in the late 60's-70's it had one. They were about 8 in. long, and went bad often. When the POA became bad they turned into a expensive orfice tube. Most cars are orfice tube systems now. (GM uses a variable displacment compressor) Neat!

I'll take a guess at this, point of access.
