Abstract Since the energy and environment issues, adsorption refrigeration technology has raised the great attention and interest by worldwide researchers and scholars, because it can efficiently use low-grade heat and its refrigerants are natural. Among the numerous working pairs of adsorption refrigeration, silica gel-water is most suitable for massive applications in solar and waste heat field, as its developed technology and low driving temperature. In this paper, application analysis of adsorption refrigeration system for solar and data center waste heat utilization and economic evaluation, based on investment of main components, operation cost and payback period, is done. For the study of solar cooling application, a validated mathematical model of silica gel-water adsorption chiller is used. For very low temperature waste heat (up to 60 °C) recovery of data center, feasibility of silica gel-water adsorption chiller has been analyzed by previous experimental study. Through the investigation, payback period of solar cooling application using adsorption chiller is too long to get any economic benefit, based on the real weather conditions of Shanghai. Data center waste heat recovery by adsorption chiller has very short payback period and this application has greater economic potential and brighter prospect in the future than solar cooling application.

太阳能及数据中心余热利用吸附式制冷系统应用分析

摘要 自能源和环境问题以来，吸附式制冷技术因其能高效利用低品位热量且制冷剂为天然材料而引起了世界范围内研究人员和学者的极大关注和兴趣。在众多的吸附制冷工作对中，硅胶-水技术发达，驱动温度低，最适合在太阳能和余热领域大量应用。本文从主要部件投资、运行成本和投资回收期等方面对太阳能和数据中心余热利用吸附式制冷系统的应用分析和经济评价。对于太阳能冷却应用的研究，使用了经过验证的硅胶-水吸附式制冷机数学模型。对于数据中心的极低温余热（高达60°C）回收，之前的实验研究分析了硅胶-水吸附式冷水机组的可行性。通过调查，根据上海的实际天气情况，采用吸附式冷水机进行太阳能制冷的投资回收期过长，无法获得任何经济效益。吸附式冷水机回收数据中心余热回收期极短，与太阳能冷却应用相比，该应用具有更大的经济潜力和更广阔的未来前景。根据上海的真实天气情况。吸附式冷水机回收数据中心余热回收期极短，与太阳能冷却应用相比，该应用具有更大的经济潜力和更广阔的未来前景。根据上海的真实天气情况。吸附式冷水机回收数据中心余热回收期极短，与太阳能冷却应用相比，该应用具有更大的经济潜力和更广阔的未来前景。
