Abstract

The solar cooling system results in a variety of technologies. It is an alternative and economical technology to conventional cooling systems and is environmentally friendly. In this work, a design of a H₂O-LiBr absorption chiller driven by a double-acting collector was proposed and studied under thermo-economic, energetic, and exergetic aspects according to Bamako climatic conditions. Higher performance was reached when the generator was operated at 85 °C, a condensing temperature of 40 °C with 8 °C as the evaporation temperature of the working fluid. The annual cooling production of the system was 52.272 MWh and the annual solar energy received on the area of the double-acting collector was 138.778 MWh. The annual energy and exergy efficiencies of the system were 0.39 and 0.025, respectively. The investment cost of the system was 36.9 k€ and the cooling cost was 0.08 €/kWh. Additionally, the simple payback period is approximately 10.4 years.

炎热地区双作用集热器辅助吸收冷却系统的设计与性能研究。

太阳能冷却系统有多种技术。它是传统冷却系统的替代技术，既经济又环保。在这项工作中，根据巴马科的气候条件，提出了一种由双作用集热器驱动的 H2O-LiBr 吸收式冷却器的设计方案，并对其进行了热经济、能耗和能效方面的研究。当发电机在 85 °C、冷凝温度为 40 °C、工作液蒸发温度为 8 °C的条件下运行时，性能更高。该系统的年制冷量为 52.272 兆瓦时，双作用集热器面积上的年太阳能接收量为 138.778 兆瓦时。系统的年能效和放能效分别为 0.39 和 0.025。该系统的投资成本为 36.9 千欧元，冷却成本为 0.08 欧元/千瓦时。此外，简单投资回收期约为 10.4 年。
