An　adsorption　bed　based　on　the　evacuated　tube　of　solar　radiation　collector　has　been　developed　and　tested　on　spot　for　its　thermal　performance.　By　analyzing　the　evolution　of　the　bed　temperature　and　the　corresponding　weather　records,　the　relevance　between　them　is　interpreted.　The　difference　of　the　thermal　performance　of　the　inclined　and　the　leveled　deployment　of　the　adsorption　bed　is　discussed.　Upon　analyzing　the　relationship　of　the　maximum/average　temperature　of　the　bed　with　the　gross　solar　radiation　heat　in　a　day,　it　is　revealed　that　there　exists　roughly　linearly　correlation　between　them.　The　test　results　show　that　the　bed　temperature　varies　along　the　circumference　less　than　along　the　radial　direction.　The　axial　non-uniformity　of　the　bed　temperature　is　attributed　to　the　end-cooling　effect　of　the　extending　part　of　the　alloy　tube.　The　time　delay　of　the　maximum　bed　temperature　with　respect　to　the　maximum　solar　radiation　is　variable　with　the　weather　condition.　The　time　delay　ranges　from　1　to　4　hours　approximately.　In　addition,　a　numerical　simulation　to　the　temperature　change　of　the　bed　for　the　2-D　case　has　been　conducted　and　the　preliminary　numerical　results　are　presented.
