Abstract

Highlights The hybrid solar heating systems help in increasing energy savings. However, an optimal configuration along with suitable control strategies will be required to enhance the thermal performance of the system. Abstract In the present work, a hybrid solar-gas heating system is built up in Algiers, Algeria, to investigate its thermal performances and thus highlight the annual solar coverage rate. The system consists essentially of two flat plate solar collectors, a gas boiler, and a hot water storage tank. The operation of the installation is controlled by data acquisition card through LabVIEW software. For this purpose, experiment tests have been conducted for different weather conditions on which the hybrid system was operating under three different scenarios simulating working days and weekends. It has been found that temperatures of the storage tank water can reach 36, 34 and 27 °C for days with a global horizontal irradiation of 390, 400 and 533 W/m^2, respectively. These preliminary results showed that temperatures of the tank under the steady state operating modes might contribute to the reduction of energy consumption for a given space heating application.

混合太阳能-燃气加热系统的实验开发

混合太阳能加热系统有助于增加能源节约。然而，优化配置以及合适的控制策略将需要提高系统的热性能。在本工作中，在阿尔及利亚阿尔及尔建立了一个混合太阳能-燃气供暖系统，以研究其热性能，从而突出年太阳能覆盖率。该系统主要由两个平板太阳能集热器、一个燃气锅炉和一个热水储存罐组成。通过LabVIEW软件控制数据采集卡的安装操作。为此，在模拟工作日和周末的三种不同情况下，对混合系统运行的不同天气条件进行了实验测试。研究发现，在全球水平辐照量分别为390、400和533 W/m^2的情况下，储罐水的温度可达36、34和27℃。这些初步结果表明，在稳态运行模式下的储罐温度可能有助于减少给定空间加热应用的能耗。图形抽象
