This　study　aims　to　develop　a　solar　multi-surface　air　collector　with　double-receiver　tubes　for　an　active-passive　ventilation　wall　with　phase　change　materials　(PCM),　in　order　to　reduce　the　dependence　on　fossil　energy　for　the　overwintering　production　in　the　solar　greenhouse,　thereby　to　improve　the　utilization　rate　of　solar　energy　resources.　A　mathematical　model　was　proposed　to　quantitatively　analyze　the　influence　of　complex　outdoor　conditions　on　the　heat　transfer　performance　of　the　developed　device.　An　evaluation　of　heating　and　configuration　requirements　was　made　when　the　device　was　used　as　a　heating　system　component　in　the　early　stage,　particularly　on　modifying　the　problem　for　the　separate　evaluation　of　the　thermal　performance　of　collectors　in　previous　most　studies.　According　to　the　characteristics　of　optical　structure　in　the　collectors,　LightTools　optical　software　was　selected　to　analyze　the　change　rule　of　sunbeams　convergence　rate　of　the　collector　with　the　receiving　angle.　The　results　showed　that　the　total　sunbeams　convergence　coefficient　of　collector　was　between　0.74　and　1,　with　the　average　value　of　0.90,　without　a　sun-tracking　device,　when　the　solar　radiation　incidence　angles　in　the　range　from　0-±20°.　In　addition,　the　ratio　of　solar　energy　received　by　each　receiver　tubes　in　the　collector　can　be　vary　with　the　change　of　receiving　angle.　A　mathematical　model　was　finally　established　with　seven　reasonable　simplified　conditions　in　the　heat　transfer　process　using　the　energy　conservation　theory,　according　to　the　optical　structure　characteristics.　Prior　to　the　mathematical　model,　two　conditions　needed　to　be　considered:　without　or　a　certain　thickness　thermal　insulation　layer　attached　to　the　outside　surface　of　reflector.　The　reason　was　that　the　thermal　insulation　layer　was　often　necessary　on　the　outside　surface　of　reflector,　in　order　to　reduce　the　emission　of　solar　energy　to　the　external　environment　via　the　reflector　in　the　cold　area　of　north　China.　A　thermal　performance　test　and　engineering　application　were　conducted　to　verify　the　proposed　model　for　the　solar　multi-surface　air　collector　with　double-receiver　tubes.　The　test　results　revealed　that,　no　matter　whether　the　outside　of　reflector　was　attached　to　the　insulation　layer　or　not,　the　average　absolute　error　was　±　0.9,　the　average　relative　error　was　3.7%,　and　the　error　analysis　index　reached　0.994.　The　average　absolute　error　along　the　length　of　collector　was　±(1.3-2.7),　verified　by　the　actual　engineering　application　of　16m　solar　multi-surface　air　collectors　with　double-receiver　tubes,　where　the　average　relative　error　was　5.4%-7.0%,　and　the　error　analysis　index　was　0.988-0.994.　Therefore,　the　results　demonstrated　that　the　mathematical　model　of　collector　can　have　a　high　prediction　effect　under　different　outdoor　meteorological　parameters,　series　length,　inlet　air　temperature,　and　air　flow　rate.　The　findings　can　guide　the　optimal　configuration　of　collector　system,　and　thereby　to　optimize　the　air　speed　of　collector,　according　to　the　changeable　outdoor　meteorological　conditions,　particularly　in　the　cold　area:　of　solar　greenhouse.　©　2020,　Editorial　Department　of　the　Transactions　of　the　Chinese　Society　of　Agricultural　Engineering.　All　right　reserved.
