提出了一种集成主动建筑集成热能存储（BITES）系统的设计和运行，以提高其热和能量性能的方法。结合预测控制策略，提出了一种基于边界条件的设计方法。预测控制使用频域模型和室内空气温度设定点曲线作为输入。根据有源BITES系统的热动态响应及其热区，以整体的方式改进了设定点轮廓和BITES设计。动态响应由频域模型的传递函数得到。该方法在通风系统上得到了验证。结果表明，该方法可以显着改善设计和运行的主动BITES系统，从而提高其热和能量性能。给出了不同尺寸系统的动力响应，为设计选型提供了有用的信息。结果表明，混凝土厚度以0.2- 0.3m为宜，可作为初始设计值。其他重要的应用考虑也进行了讨论。
A methodology is presented for integrating the design and operation of active building-integrated thermal energy storage (BITES) systems to enhance their thermal and energy performance. A bounding-condition based design approach is proposed in conjunction with predictive control strategies. The predictive control uses frequency domain models and room air temperature set-point profile as input. The set-point profiles and BITES design are improved in a holistic manner according to the thermal dynamic response of active BITES systems and their thermal zones. The dynamic response is obtained from the transfer functions of frequency domain models. The methodology is demonstrated on ventilated systems. The results show that the methodology can significantly improve the design and operation of active BITES systems, and hence improve their thermal and energy performance. The dynamic response of different sizes of systems is presented to provide useful information for design selection. It is shown that concrete thickness of 0.2–0.3 m is a good value to initiate design. Other important application considerations are also discussed.
