摘要

摘要:太阳能热水器是一种高效、可持续的技术,可满足住宅和商业应用中日益增长的热水需求。本摘要通过广泛的实验研究,全面概述了太阳能热水器系统的性能评估。研究旨在评估不同太阳能热水器配置在不同运行条件下的效果和效率。实验调查涉及对太阳能集热器效率、传热效率、蓄热能力和系统整体效率等关键性能参数的测量和分析。系统地改变了一系列因素,包括太阳辐射强度、环境温度、水流量和集热器倾斜角度,以检查它们对系统性能的影响。实验研究结果表明,太阳能热水器在提供经济、环保的热水解决方案方面具有巨大潜力。研究发现,太阳能集热器的效率受太阳辐射强度的影响很大,太阳辐照度越高,产生的热能就越多。通过调整水流量和集热器倾斜角度,优化了传热效率,确保了热量从集热器到水中的高效传递。此外,该系统的蓄热能力在太阳辐射低或需求高期间保持稳定的热水供应方面发挥了至关重要的作用。研究发现,系统的整体效率在很大程度上取决于高效热交换器和保温材料的集成。根据实验结果,提出了系统设计和优化的建议,强调了适当的尺寸、选择合适的材料和适当的控制策略的重要性。实验结果还确定了未来的研究领域,如先进传热增强技术的集成和混合太阳能热水器系统的利用。

Comprehensive Performance Analysis of Hybrid Solar Water Heating Systems: Synergizing Photovoltaic and Thermal Technologies
Abstract: Solar water heaters are an efficient and sustainable technology for meeting the growing demand for hot water in residential and commercial applications. This abstract presents a comprehensive overview of the performance evaluation of solar water heater systems through an extensive experimental study. The study aims to assess the effectiveness and efficiency of different solar water heater configurations under varying operating conditions. The experimental investigation involved the measurement and analysis of key performance parameters such as solar collector efficiency, heat transfer efficiency, thermal storage capacity, and overall system efficiency. A range of factors including solar radiation intensity, ambient temperature, water flow rate, and collector tilt angle were systematically varied to examine their impact on system performance. The results of the experimental study demonstrated the significant potential of solar water heaters in providing cost-effective and environmentally friendly hot water solutions. The solar collector efficiency was found to be highly influenced by the solar radiation intensity, with higher levels of solar irradiation leading to increased thermal energy generation. The heat transfer efficiency was optimized by adjusting the water flow rate and collector tilt angle, ensuring efficient transfer of heat from the collector to the water. Furthermore, the thermal storage capacity of the system played a crucial role in maintaining a consistent supply of hot water during periods of low solar radiation or high demand. Overall system efficiency was found to be strongly dependent on the integration of efficient heat exchangers and insulation materials. Based on the experimental findings, recommendations for system design and optimization were formulated, highlighting the importance of proper sizing, selection of suitable materials, and appropriate control strategies. The results also identified areas for future research, such as the integration of advanced heat transfer enhancement techniques and the utilization of hybrid solar water heater systems
