[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.%[目的]提高日光温室主动蓄热能力,使温室内热环境得到保障.[方法]提出一种新型双集热管多曲面槽式空气集热器,将此集热器与日光温室后墙结合构成主-被动式墙体体系,将此墙体体系应用于新疆日光温室,研究该集热器在日光温室中应用的可行性及应用效果.[结果]在集热器长度为16 m、集热器单支玻璃管接收器内空气流速为2.5 m/s的条件下,集热器出口温度可达75℃,集热效率可达50%.该集热系统通过日光温室墙体主动蓄热方式,在冬季实测期间累计可为日光温室提供约为2 400 MJ的太阳能.[结论]该结果可为集热器的推广应用提供参考.
