摘要
太阳能热水器是一种收集太阳辐射并转换成热能的装置。重点回顾了近年来太阳能热水器高效利用技术的研究和发展状况,主要包括太阳能集热器的优化改进、热水器运行策略制定、将太阳能热水系统与其他能源设备的结合使用等方面。通过综述近年来的相关文献资料发现,提高太阳能热水器集热和换热性能仍是提高太阳能热水器效率的最直接措施,但基于现有技术改善太阳能热水器的运行方式,以及协调使用太阳能与其他能源的热水器也能提高热水器的效率。最后笔者从运行控制策略的角度提出了针对太阳能热水器高效利用的设想和潜在的研究方向。
Solar water heater is a kind of device that collects solar radiation and converts solar into heat for heating the water. This paper focuses on the research and development of efficient utilization of solar water heaters in recent years, including the optimization and improvement of solar collectors, the operation strategy of water heaters and the combination of solar water heating systems and other energy equipment. By reviewing relevant literatures in recent years, it is found that improving the heat collecting and heat transfer performance of solar water heaters is still the most direct measure to enhance the efficiency of solar water heaters. However, the operation mode of solar water heaters based on the prior technology and the use of solar water heaters combined with other energy can also improve the efficiency of water heaters. Finally, the author proposes the idea and potential research directions for high efficient utilization of solar water heaters from the perspective of operational control strategy. Keywords：solar energy; solar water heater; high efficient utilization
