本文提出了一种创新的水光伏集热器原型。这种系统的主要新颖之处之一是通过低成本材料获得的经济可承受性。该集热器在帕特雷大学（希腊）建造并进行了实验测试，由一个多晶光伏模块组成，该模块连接到11个用于水加热的塑料管，位于铝盒中的光伏板下方。该样机可为建筑提供生活热水和电力，适合于建筑一体化。为了评估系统在不同天气条件下和不同建筑用途下的能源、经济和环境性能，开发了一个合适的动态模拟模型，并与实验数据进行了验证。为了研究所提出的原型的方便性和开发的软件的潜力，一个合适的案例研究。特别地，光伏集热器耦合到分层热水存储箱，用于向位于三个不同的欧洲气候区（弗赖堡、那不勒斯和阿尔梅里亚）的单户住宅供应家用热水。通过对一些设计和运行参数的能量和经济敏感性分析，对系统布局进行了优化。获得了有用的设计准则和有趣的能源和经济结果。(C)2019爱思唯尔有限公司版权所有。
This paper presents an innovative water photovoltaic thermal collector prototype. One of the main novelties of such system is its economic affordability, obtained through low-cost materials. The collector, constructed and experimentally tested at the University of Patras (Greece), is composed of a poly-crystalline photovoltaic module coupled to eleven plastic pipes for water heating, located under the PV panel in an aluminium box. The prototype, suitable for building architectonical integration, can provide domestic hot water and electricity to the building. In order to assess the energy, economic and environmental performance of the system under different weather conditions and for diverse building uses, a suitable dynamic simulation model was developed and validated vs. experimental data. To investigate the convenience of the presented prototype and the potentiality of the developed software, a suitable case study is presented. In particular, the photovoltaic thermal collector is coupled to a stratified hot water storage tank for supplying domestic hot water to a single-family house located in three different European weather zones: Freiburg, Naples and Almeria. The system layout optimization was also performed through an energy and economic sensitivity analysis to some design and operating parameters. Useful design criteria and interesting energy and economic results were obtained. (C) 2019 Elsevier Ltd. All rights reserved.
