The　application　of　greenhouse　technologies　is　rapidly　expanding　in　China　and　other　regions　of　the　world　with　the　continental　climate.　Such　technologies　are　characterized　by　a　considerable　consumption　of　fossil　fuels,　especially　in　winter　periods.　Various　renewable　energy　technologies　are　used　to　reduce　the　energy　demand　in　greenhouses,　including　solar　heating.　Simpler　designs　of　water　or　air　solar　collectors　are　preferred　without　sun-tracking　devices　and　reduced　dimensions　and　weight.　In　this　work,　a　novel　solar　multi-surface　air　collector　with　double-receiver　tubes,　which　does　not　require　a　sun-tracking　device　is　proposed　and　has　increased　concentration　ratio　and　sun　rays　convergence　and　reduced　thermal　losses.　The　laboratory　and　full-scale　prototypes　of　the　proposed　novel　collector　were　manufactured　and　tested　in　laboratory　conditions　during　the　December-January　period　as　a　part　of　the　greenhouse　with　the　active-passive　ventilation　wall　and　latent　thermal　storage,　located　in　the　Beijing　Region.　Results　of　experiments　demonstrate　that　the　solar　collector　increases　the　average　temperatures　of　the　greenhouse　north　wall　inner　surface　by　7.5　degrees　C,　indoor　air　during　the　night-time　by　1.8　degrees　C　and　indoor　soil　by　1.5　degrees　C.　The　novel　collector　provided　active　heat　gains　of　11.831　GJ　during　the　December-January　period　and　satisfied　from　11%　to　81%　of　the　heat　load.　A　lumped　parameter　mathematical　model　of　the　proposed　collector　was　developed,　and　the　comparison　of　simulation　results　and　experimental　data　demonstrate　its　high　accuracy　in　prediction　of　the　collector　performance.　The　model　was　used　to　study　the　influences　of　outdoor　meteorological　parameters,　air　velocity　in　the　receiver　tubes　and　their　length　on　the　performance　of　the　collector.　This　data　was　used　to　determine　the　rational　design　parameters　and　air　velocity　of　the　full-scale　collector.　The　model　was　also　used　to　rationalize　the　variation　of　air　velocity　in　the　receiver　tube　during　the　day.
