Abstract: [Objective] In order to improve the heat storage capacity of solar greenhouse, which guaranteed the thermal environment within the greenhouse.[Method]This study proposed a new type multiple clamber trough solar air collector with dual collector tubes, combined with a solar greenhouse back wall to form active-passive wall system, which was applied in Urumqi Solar Greenhouse.The experiment was carried out to investigate the feasibility and application effects of the collector.[Result]The results showed that: when the collector length is 16m and the air velocity inside the single concentrator is 2.5 m/s, the outlet temperature of the collector could reach 75℃ and the collector efficiency could reach 50;;The heat collecting system could provide solar thermal energy about 2,400 MJ for solar greenhouse by active heat storage of the wall during the winter test period.[Conclusion]This study can provide a reference for the popularization and application of the collector.
