Access Port
An access port is used to add refrigerant to the system or for measurement.
An access port is typically installed in the liquid line in a convenient location
and is used to charge the system with liquid refrigerant. It is also used to
measure subcooling.
The suction line typically includes two access ports. One is installed near the
compressor and is used to measure suction pressure. The other is located near
the external equalizer-line connection for the expansion valve, and is used to
measure superheat when checking or adjusting the expansion valve setting.
