Solar　energy　is　a　kind　of　renewable　energy　with　abundant　resources　and　enormous　reserves.　Meanwhile,　adsorption　cooling　technology　can　utilize　natural　refrigerants,　thus　also　making　this　technology　environmentally　friendly.　If　solar　energy　can　be　effectively　collected　and　utilized　for　heating　in　winter,　then　the　environmental　pollution　caused　by　electricity　and　fossil　energy　consumption　can　be　reduced.　More　importantly,　considering　engineering,　the　same　solar　device　could　provide　cooling　in　the　summer　and　heating　in　the　winter.　This　study　used　parabolic　trough　and　glass-metal　vacuum　heat　collectors　to　conduct　solar　adsorption　cooling　and　solar　air　heating　experiments　in　summer　and　winter,　respectively,　to　facilitate　the　complete　and　appropriate　use　of　solar　energy.　Experimental　results　of　solar　adsorption　cooling　with　silica　gel　as　the　adsorbent　revealed　that　the　coefficient　of　performance　of　the　system　reached　0.329.　In　addition,　the　influences　of　air　flow　rates　and　heat　storage　medium　on　the　performance　of　the　solar　air　heating　system　were　investigated.　Results　revealed　that　the　average　and　instantaneous　efficiencies　of　the　system　considerably　increased　with　the　heat　storage　medium　(i.e.,　water)　filling　in　the　annular　cavity　of　the　evacuated　tube.　The　extended　heating　time　also　markedly　increased　by　up　to　170　min　and　was　therefore　of　considerable　practical　value.
