The negative impacts of the increasing number of air conditioning systems in Australia include excessive strain on grids and associated blackouts, higher electricity costs and associated carbon emission issues. The installation of sustainable cooling technologies such as solar absorption cooling systems provides a promising alternative. However, the feasibility of the system for the Australian subtropical climate has not systematically studied. The paper aims to investigate the feasibility of implementing solar absorption cooling technology in student residential building in Australia's subtropical climate region. The feasibility study allows the user to determine if the solar cooling system is technically, economically and environmentally sustainable in the long term. Through the simulation, the key performance parameters such as power consumption data and component performance details were determined. The simulation results showed that the solar absorption chiller can provide comfort in the building by maintaining room temperature within 20–24 °C. The system's performance optimisation studies were conducted, and it was found that the collector area 20 m² paired with a storage ratio of 0.02 m³/m² had provided a high solar fraction (SF) of 0.91. The economic analysis is also carried out to determine the annual savings in energy cost, carbon emission reduction, and the payback period.

澳大利亚空调系统数量增加的负面影响包括电网过度紧张和相关停电、电力成本增加和相关碳排放问题。太阳能吸收冷却系统等可持续冷却技术的安装提供了一个有前途的替代方案。然而，该系统对于澳大利亚亚热带气候的可行性尚未系统研究。本文旨在探讨在澳大利亚亚热带气候区的学生住宅楼中实施太阳能吸收冷却技术的可行性。可行性研究允许用户确定太阳能冷却系统在技术、经济和环境方面是否具有长期可持续性。通过模拟，确定了关键性能参数，例如功耗数据和组件性能细节。模拟结果表明，太阳能吸收式制冷机可以通过将室温保持在 20–24 °C 内为建筑物提供舒适度。对该系统进行了性能优化研究，发现集热面积20 m²与 0.02 m ³ /m ²的存储比配对提供了 0.91 的高太阳能分数 (SF)。还进行经济分析以确定每年节省的能源成本、碳排放量和投资回收期。
