Polysiloxane Radiative Cooling Paints for the Decarbonisation of Cooling in the Built and Transport Environments (PolyCool)

室内空间的降温是人们获得良好健康和福祉的基本手段，但也是与人类活动相关的最耗能和高污染的过程之一。统计数据令人震惊；空调(AC)和电风扇占当今世界建筑物总用电量的20%左右，每年产生的二氧化碳排放量超过1.2GT。同样，在炎热的天气里，交流电源可能占到电动汽车电池使用量的40%。为了应对气候变化，加速向碳中性经济转型，欧盟绿色协议的首要目标是节能和可持续的室内空间和车辆冷却技术。PolyCool的总体目标是开发零能源投入、零排放(在使用过程中)辐射冷却涂料/涂料，这种涂料还结合了商业、工业和住宅建筑的成本效益和低维护。经过适当的修改，这项技术还将能够部署在汽车行业，以及更广泛的交通行业。这项拟议的技术利用了寒冷宇宙的无限热能，将其本质上转化为取之不尽的散热器，用于储存地球上建造的环境和车辆发出的热辐射。关键是，它完全是被动的，不需要电动泵、风扇或冷却器来操作。PolyCool涂层将能够提供&gt；100W/m2的冷却功率，能够满足典型住宅的至少30%的冷却需求。这个项目的主要目标是：i)开发一个大型原型(&gt；20厘米x 20厘米)。2)在实地、不同地理位置和不同气候条件下对原型进行广泛的测试。Iii)巩固强大的知识产权地位，以及(Iv)制定商业化路线图，将PolyCool技术从实验室台式平台推向市场。

Cooling of indoor spaces is a fundamental means to attain peoples' Good Health and Well Being, yet is one of the most energy intensive and highly polluting processes associated with human activity. The statistics are staggering; air-conditioners (AC) and electric fans account for ~20% of the total electricity consumed in buildings around the world today and contribute over 1.2 GT of CO2 emissions per year. Likewise, AC may be responsible for 40% of an electric vehicle's battery usage on a hot day. To combat climate change and accelerate the transition towards carbon neutral economies, paramount targets of EU's Green Deal, energy efficient and sustainable indoor space and vehicle cooling technologies are imminently required.PolyCool's overarching objective is to develop zero-energy input, zero-emissions (during usage) radiative cooling coatings/paints, which also combine cost efficacy and low-maintenance for commercial, industrial and residential buildings. With proper modifications, the technology will also be able to be deployed in the automotive and more broadly in the transportation industry as well. The proposed technology is leveraging the infinite heat capacity of the cold Universe, converting it in essence into an inexhaustible heatsink for the thermal radiation emitted by the built environment and vehicles on Earth. Crucially, it is completely passive and does not require electric pumps, fans or coolers to operate. PolyCool coatings will be able to provide a cooling power of >100 W/m2, able to cover at minimum 30% of a typical residency's cooling needs. The key objectives of this project are; i) Develop a large -scale prototype (>20 cm x 20 cm). ii) Perform extensive testing of the prototype in the field, in various geographical locations and under various climatic conditions. iii) Consolidate a strong intellectual property position and, iv) develop a commercialisation roadmap to translate PolyCool technology from the lab benchtop to the market.
