【摘要】 基于能量平衡原理对耦合中置式光伏Trombe墙的房间建立热舒适性动态评价模型,在冬季供暖模式下,对室内热舒适性进行评价,并研究了吸热板安装位置对室内热舒适性的影响。结果表明,中置式光伏Trombe墙虽能提升室内热舒适性,但仅能将室内热环境维持在基本舒适状态,从9:00到13:00室内热环境都偏冷,人体感觉不舒适。在太阳辐射强度较低时,太阳电池板和玻璃盖板形成的封闭空气夹层能使室内仍可以维持在较为舒适的温度。将吸热板安装到集热墙外表面,能在不增加成本的前提下,有效改善室内热环境,缩短室内不舒适时间1 h。采用文中构建的热舒适性评价模型可以方便地预测不同时刻室内热舒适性的变化情况,实现室内温度的动态管理。

【Abstract】 A thermal comfort evaluation model, based on energy balance principles, is developed for assessing indoor thermal comfort in a room equipped with a built-middle PV-Trombe wall during the heating season. The study also investigates how the installation location of the absorber plate affects indoor thermal comfort. Results show that while the built-middle PV-Trombe wall improves indoor thermal comfort, it maintains only a basic level of comfort overall. Between 9: 00 and 13: 00, the indoor environment remains cold, resulting in occupant discomfort. However, when solar radiation is low, the enclosed air layer formed by the photovoltaic panel and glass cover can still help maintain a more comfortable room temperature. Positioning the absorber plate on the outer surface of the massive wall enhances the indoor thermal environment, reducing discomfort duration by one hour without additional costs. The thermal comfort evaluation model constructed here allows for easy prediction of indoor thermal comfort variations over time, facilitating dynamic management of indoor temperature.
