Abstract：

A　design　method　of　a　flat　plate　solar　water　heating　system　is　presented.　By　analyzing　the　thermal　efficiency　of　the　whole　system,　it　is　obtained　that　daily　radiant　exposure　is　inversely　proportional　to　the　system　efficiency.　The　condition　that　the　heat　gain　in　the　system　is　proportional　to　the　daily　radiant　exposure　is　achieved.　The　influencing　factors　of　the　appearance　time　of　the　maximum　temperature　in　the　water　tank　are　obtained.　The　applicability　of　the　double　loop　solar　water　heating　system　in　Beijing　is　demonstrated　in　the　experiments,　and　the　system　efficiency　is　59.5%.　©　2011　IEEE.
