摘　　要：针对一种太阳能空气-水双集热功能的平板式集热器开展研究。将集热器与具有蓄热特性的建筑南墙结合,建立实验平台,并构建了集热器被动采暖空气集热模式的瞬态理论模型。利用数值迭代方法对模型进行求解,并将计算结果与实验数据进行对比,对理论模型进行实验验证。结果表明,计算结果和实测数据结果吻合良好,模型可以准确模拟被动采暖模式下集热器、房间围护结构和空气的温度场以及温度随变化的变化情况。The dual-function solar collector which can work in either air heating or water heating mode is investigated. The collector was integrated with southern wall of the building and mathematical model of the system working in passive heating mode was set up. The results of the numerical simulation were compared with the experimental results. It shows that numerical results are well consistent with the experimental results. Temperatures of each component of the collector and building can be calculated by the numerical simulation correctly.
