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。
Construction of solar energy - phase change thermal storage - fresh air heating system used to bear the burden of building fresh air, with all-glass vacuum tube collector as a system of thermal components, phase change thermal storage as a system thermal storage components, air - water heat exchanger As the system heating end. By making the system run different modes to achieve the purpose of the unstable solar energy into a stable heating heat source. The dynamic simulation model of the coupling system is established and verified by experiments. According to this model, the optimal design parameters of the system (collector flow, phase change material quality, phase transition temperature, etc.) and operation strategy are studied.
