Portion port, air accumulator 3 is connected to bottom port, and when air-conditioning normal use, bottom port is closed, and hydrogen inputs or defeated from top port
Go out chamber；And when the dusting degree of the detection of air-conditioning metal hydride in the present invention, first make detected metal hydride hydrogen release,
The indoor hydrogen of chamber to be discharged, then closure tip port and bottom port is opened, and be filled with into chamber from bottom port
Inert gas, this kind have the advantage that, the light specific gravity due to hydrogen than inert gas, so upon completion of the assays, passing through
Open top part port and bottom port, it is the top in chamber to re-fill the indoor hydrogen of chamber, and inert gas is to be in chamber
Inert gas can be gradually expelled to from bottom port in air accumulator 3 by the lower part of room with increasing for chamber, to not
On the basis of influencing the normal hydrogen conveying of air-conditioning, the storage again of inert gas can also be realized, to meet the need of repeated detection
It wants.
Inert gas of the present invention includes the gas types such as helium, neon, argon, krypton, xenon and radon, it should be noted that this
The gas being filled with when invention detection can not also be limited to inert gas, not reacted with hydrogen, not by metal as long as disclosure satisfy that
