Abstract


  • This paper presents the performance evaluation and design optimization of a ceiling ventilation system with

    integrated solar photovoltaic thermal (PVT) collectors and phase change materials (PCMs) by using a hybrid

    Particle Swarm Optimization and Hooke-Jeeves Pattern search (PSO-HJ) algorithm. In this novel ceiling

    ventilation system, the PVT collectors are used to generate electricity and provide the low-grade heating

    energy for buildings by using the winter daytime solar radiation, while the PCM is integrated into the building

    ceiling as part of the ceiling insulation and at the same time, as a centralized thermal energy storage unit to

    temporally store the low-grade thermal energy collected from the PVT collectors and use it later when

    needed. The benefit of using this proposed PVT-PCM integrated ceiling ventilation system in active buildings

    with air-conditioning systems was evaluated in terms of the total power consumption of the house for space

    heating. Further optimization was performed in order to identify the optimal values of the key design

    parameters. In the hybrid PSO-HJ algorithm used in the design optimization, the PSO is first used to identify

    the optimal region of the design variables while the HJ algorithm is then used to perform a local search to

    identify the “global” optimal values. The results showed that the integration of PVT collectors and PCMs with

    the ceiling ventilation can greatly reduce the power consumption of the house for space heating in winter. By

    employing the optimal design identified using PSO-HJ algorithm, the power consumption of the house can

    be further reduced.
