Description
Large particle accelerators, such as the LHC, ILC, and proposed CEPC, face significant challenges, including the massive energy consumption due to their high energy demands, while China strives to reduce energy pollution and promote the carbon neutrality by 2060. In this study, we conducted extensive research on waste heat recovery and reuse for CEPC. The first step is to comprehend the particular requirements for waste heat recovery and utilization in CEPC. The basics of Absorption Heat Pumps (AHP), a technology that enables the conversion of low-grade waste heat into usable high-grade energy, are then investigated. Based on this technology, a photovoltaic (PV) to heat → absorption heat pumps (AHP) scheme is proposed and the economic analysis is provided for reusing CEPC waste heat, which offers a cost-effective solution with a relatively small initial investment for substantial long-term gains. In summary, the energy recovery and reuse technology studies for large green accelerators are relatively new but crucial topic in this field. This project aims to develop the waste heat recovery technologies of the accelerator, and provide fundamental research assistance for the "green" energy-saving transformation of China's particle accelerator. Further green accelerator development & research works are still going on.
