STUDY ON CONTROL STRATEGY FOR SOLAR AIR COLLECTOR INTEGRATED WITH BUILDING

该研究利用可调控的风机和风门,对两种类型集热模块的热输送过程进行了优化实验研究,系统探讨了在供热模式下空气循环方式、模块类型以及质量流率等因素对模块内部空气升温速度、供热量及集热效率等的影响,并提出集热模块运行控制的基本策略。同时通过对模块的简化计算模型进行理论分析,提出了集热模块的运行控制参数方程,为实现模块运行的优化控制提供理论依据。

Indoor air temperature is directly affected by heat transport of the solar air collector integrated with buildings.The adjustable fans and vents were used to optimize the heat transport process for two types of solar air collector by experiment in the paper. The effects of air circulating mode, collector type and mass flow rate on air temperature rise, heat supplied, as well as heat efficiency of collectors were discussed in detail, and the control strategy for solar air collector integrated with buildings was developed. Meanwhile, theoretical analysis was done by using a simplified model, in which the governing equations were proposed. The results can provide theoretical foundation for optimizing the control strategies of solar air collector integrated with buildings
