摘要
构建太阳能-相变蓄热-新风供暖系统用于承担建筑新风负荷,以全玻璃真空管集热器作为系统集热组件,以相变蓄热装置作为系统蓄热组件,以空气-水换热器作为系统供暖末端。通过使系统运行不同模式的方式达到将不稳定的太阳能变为稳定供暖热源的目的。建立耦合系统动态仿真模型并对其进行实验验证。依据此模型对系统最佳设计参数(集热系统流量、相变材料质量、相变温度等)和运行策略进行研究。
The solar energy-phase change thermal storage-fresh air heating system was built to afford building fresh air heating load. In this system, all-glass vacuum tube solar collector was taken as system＇ s heat source. The phase change thermal storage equipment was taken the core heat storage component of this system. The air-water heat exchanger was taken as the system＇ s heating end. By running the different modes of the system, the unstable solar energy was changed with the stable heat source. A model describing the transient behavior of system was first establishes in this paper and the model was validated by experiment. Then, based on this model, the system design parameters （collector system flow rate, quality of phase change materials, phase change temperature, etc. ） and operating strategies were investigated.
