In　order　to　explore　the　application　of　solar　energy　in　heat　storage　and　heating,　a　set　of　solar-powered　open　cycle　system　of　heat　storage　was　proposed　to　investigate　experimentally　the　thermal　utility　of　solar　energy.　Experiments　were　performed　by　means　of　natural　zeolite-water　as　adsorption　medium　for　possible　application　in　winter.　Based　on　continual　observation　of　solar　radiation,　the　dynamic　properties　of　adsorption　process　or　desorption　process　of　the　natural　zeolite　heat　storage　bed　have　been　determined　and　the　amount　of　thermal　energy　available　and　thermal　efficiency　were　calculated.　It　was　showed　that　absorption　heat　and　desorption　heat　were　about　152.5　kJ　and　2126　kJ,　respectively.　Then,　thermal　efficiency　of　the　solar　energy　storage　set　was　higher　than　30%　in　present　study.
