This paper deals with both energetic and economic studies of a new integrated collector storage with honeycomb transparent insulation (ICSHTI) which was conceived, developed, and tested in the Research and Technology Centre of Energy (CRTEn), Tunisia. Experimental and numerical studies were performed in order to evaluate the thermal and the economic performances of the new solar collector configuration. Investigations are based on the daily efficiency, the heat loss coefficient and the long‐term performances. The results showed that the ICSHTI presents a mean daily efficiency around 51.60% and a heat loss coefficient equal to 5.51 W/m²K. Results also showed that the energy loaded from the ICSHTI is about 4,669 MJ which represents about 57% of the total domestic hot water (DHW) needs by considering only solar energy. By considering different scenarios of climatic conditions, TRNSYS and SOLO investigations showed that the average solar fraction is about 67 and 28% in hot and cold regions, respectively. To evaluate the feasibility of integrating the ICSHTI in local market, a comparison against the most commercialized DHW systems namely the flat‐plate solar collector (FPC) was conducted. The results showed that the FPC is more economical than the ICSHTI with a yearly economy Y_OER and a payback period P_T equal to 120.2 US$/year and 12 years for the FPC and 102.3 US$/year and 14.3 years for the ICSHTI when we considered the P_T based on electric water heater. However, when we considered a P_T based on gas water heater, the ICSHTI system becomes more economical than the FPCDHW with a P_T equal to 18.5 years and 20.5 years, for the two systems, respectively.

新型带有蜂窝状透明绝缘材料的集成集热器储能的经济性和经济性分析（ICSHTI）

本文研究和研究了一种新型的带有蜂窝状透明绝缘材料的集成集热器储存器（ICSHTI），该储存器是在突尼斯能源研究和技术中心（CRTEn）中构思，开发和测试的。为了评估新型太阳能收集器配置的热性能和经济性能，进行了实验和数值研究。研究基于日常效率，热损失系数和长期性能。结果表明，ICSHTI的日平均效率约为51.60％，热损失系数等于5.51 W / m ²K.结果还表明，仅考虑太阳能，ICSHTI装载的能量约为4,669 MJ，约占总家用热水（DHW）需求的57％。通过考虑不同的气候条件，TRNSYS和SOLO的研究表明，炎热和寒冷地区的平均太阳分率分别约为67％和28％。为了评估将ICSHTI集成到本地市场的可行性，我们与最商业化的DHW系统即平板太阳能收集器（FPC）进行了比较。结果表明，FPC比ICSHTI更经济，年经济为O _OER，投资回收期为P _T等于120.2 US $ /年和12年的FPC和102.3 US $ /年和14.3年的ICSHTI当我们考虑的P_牛逼基于电热水器。但是，当我们考虑基于燃气热水器的P _T时，ICSHTI系统变得比FPCDHW更经济，两个系统的P _T分别等于18.5年和20.5年。
