Purge system for an absorption air conditioner

摘要

Apparatus for purging non-condensable gases from an absorption system containing a purge tank connected to the system absorber for collecting non-condensables. A vacuum pump is connected to the tank for drawing the non-condensable gases from the tank and exhausting them to ambient. A solenoid actuated valve is mounted in the vacuum pumps discharge line which is arranged to close immediately when the pump is rendered inoperative during a normal shutdown or during a power failure.
