CoolerSun: creating a clean and reliable cooling, heating, water treatment and electricity in Sub-Saharan Africa

预计住宅制冷行业在21世纪将增长10倍以上，其中大部分增长在热带和新兴国家，受到全球变暖的进一步影响。到2018年底，仅用光伏发电为制冷行业供电就需要全球光伏装机容量的20倍[Peters 19]。CoolerSun是一种智能解决方案，其制冷效率是光伏发电的三倍，制冷服务覆盖率高达80%。这可以通过使用热高效太阳能聚光器，加上能量储存和冷却器来实现。提出的解决方案可以提供水净化、食品储存、灵活供暖、热水和电力，并将重点放在撒哈拉以南非洲和南亚的发展中国家。CoolerSun智能地使用标准的20‘或40’集装箱，用于运输工厂部件，也用于永久托管技术设备（净水器，冷水机，储能）和支持太阳能集热器。集装箱化的解决方案，预先安装电缆和管道，允许快速和可靠的安装。标准化的布局和布线使设备维护和远程控制变得容易。该系统可以从一个站点移除并重新安置到其他地方。CoolerSun工厂标准配备了FocalSun的太阳能聚光器和存储设备，并可根据当地需要定制冷却器和水净化机械，为当地社区提供各种服务：低温食品保存、环境加热/冷却、热水、水处理以及满足社会和工业需求的电力。CoolerSun可以批量生产；通过多个相互连接的模块化单元，可以为城市和农村地区的客户产生所需的冷却和水净化需求。CoolerSun重量轻，是第一个可以安装在屋顶上的集中太阳能交钥匙解决方案。第一阶段可行性项目将探索在撒哈拉以南非洲城镇的工业平屋顶上安装CoolerSun解决方案的市场潜力和设计要求。该项目的第一阶段将允许该财团为特定应用开发CoolerSun系统设计，模拟其输出并评估其市场潜力。第一阶段还将确定CoolerSun解决方案最重要的要求和优先事项，这些要求和优先事项将为赞比亚当地客户增加最大的经济和社会价值。

The residential cooling sector is expected to grow by more than 10-fold during the 21st century, with most of the growth in tropical and emerging nations, further impacted by global warming. Powering the cooling sector with PV alone would require 20 times the global PV capacity installed at end 2018 [Peters 19].CoolerSun is a smart solution able to generate cooling power with up to three times the efficiency possible with PV, and better cooling service coverage up to 80%. This is made possible by using thermal high-efficiency solar concentrators, coupled with energy storage and chillers. The proposed solution can provide water purification, food storage, flexible heating, hot water, electric power and is focused on developing countries of Sub-Saharan Africa and South Asia.CoolerSun makes smart use of standard 20' or 40' containers, used to ship plant parts, but also to permanently host technical equipment (water purifier, chiller, energy storage) and supporting the solar collectors. The containerised solution, with pre-installed cabling and piping, allows fast and reliable installation. The standardised layout and cabling make easy the plant maintenance and remote control. The system can be removed from a site and relocated elsewhere.CoolerSun plants have the FocalSun's solar concentrators and storage come as standard and can be customised to also have chillers and water purification machinery, depending on the local need, providing a variety of services to local communities: low-temperature food conservation, ambient heating/cooling, hot water, water treatment, and electric power for social and industrial needs. CoolerSun can be mass-produced; with multiple interconnected modular units can generate the required needs for cooling and water purification for customers in urban and rural areas. CoolerSun is lightweight and is the first concentrated solar turnkey solution that can be installed on a rooftop.The Phase 1 Feasibility project will explore the market potential and design requirements to install the CoolerSun solution on industrial flat roofs in the towns and cities in Sub-Saharian. Phase 1 of the project will allow the Consortium to develop CoolerSun system design for the specific applications, modelling its output and assess its market potential. Phase 1 will also ascertain what the most important requirements and priorities for CoolerSun solution that will add the most economic and social value to local Zambian customers.
