Abstract

The integration of electric underfloor heating systems with photovoltaic (PV) panels presents a promising approach to enhance thermal efficiency and energy sustainability in residential heating. This study investigates the performance of such hybrid systems under different energy supply scenarios. Numerical modeling and simulations were employed to evaluate underfloor heating performance using three electricity sources: standard electric supply, solar-generated energy, and a combined configuration. Solar irradiance sensors were utilized to collect input solar radiation data, which served as a critical parameter for numerical modeling and simulations. The set outdoor air temperature used in the analysis represents an average value calculated from data measured by environmental sensors at the location of the building during the monitored period. Key metrics included indoor air temperature, time to thermal stability, and heat loss relative to outdoor conditions. The combined electric and solar-powered system demonstrated thermal efficiency, improving indoor air temperature by up to 63.6% compared to an unheated room and achieving thermal stability within 22 h. Solar-only configuration showed moderate improvements. Heat loss analysis revealed a strong correlation with indoor-outdoor temperature differentials. Hybrid underfloor heating systems integrating PV panels significantly enhance indoor thermal comfort and energy efficiency. These findings support the adoption of renewable energy technologies in residential heating, contributing to sustainable energy transitions.

光伏集成增强地板电采暖的数值评价。

将地板下电采暖系统与光伏（PV）板相结合，为提高住宅采暖的热效率和能源可持续性提供了一种有前途的方法。本文研究了在不同能源供应情况下，这种混合系统的性能。采用数值建模和仿真方法，对三种电源（标准电源、太阳能电源和组合配置）的地板采暖性能进行了评估。利用太阳辐照度传感器采集输入的太阳辐射数据，作为数值模拟的关键参数。分析中使用的室外空气温度设置是根据监测期间建筑物所在位置的环境传感器测量的数据计算的平均值。关键指标包括室内空气温度、热稳定时间和相对于室外条件的热损失。与未加热的房间相比，电力和太阳能组合系统显示出热效率，将室内空气温度提高了63.6%，并在22小时内实现了热稳定性。仅太阳能配置显示出适度的改善。热损失分析显示与室内外温差有很强的相关性。混合地板采暖系统集成光伏板显著提高室内热舒适性和能源效率。这些发现支持在住宅供暖中采用可再生能源技术，有助于可持续能源转型。
