Purge Tank Subsystem
Any non-condensables that have accumulated from the
refrigerant vapor are left behind to collect in the purge
tank. As the quantity of non-condensables increases,
the heat transfer efficiency of the purge evaporator coil
is reduced, causing the purge compressor suction
temperature to decrease.
A float switch, mounted in the bottom of the purge
tank, indicates if there is excessive accumulation of
liquid refrigerant in the tank. A liquid level sensor,
which resides in the purge control panel, monitors the
status of the float switch.
If the normally closed float switch is open for more
than 20 minutes, the purge controls will turn off the
