Air Cooling for EV Thermal Management (AIRCOOL)

供暖、通风和空调（HVAC）系统是一种能源密集型系统，对所有车辆都是一个挑战。当电力电子设备和电动机形成推进系统的关键部分时，例如在EV中，这种情况会加剧。HVAC系统通常消耗20% - 40%的电动汽车的范围取决于HVAC系统的效率，这可能会因不同的车辆而异。这个为期6个月的项目建立在最近的IDP-14可行性研究的基础上，旨在验证布鲁内尔大学进行的建模工作和小规模的内部台架测试。本研究的目的是运行FeTu的新型空气循环，一种无制冷剂冷却系统，在一个专门建造的测试台上模拟电动汽车热管理系统。以前的工作表明，FeTu的空气循环可以与传统的蒸汽压缩系统竞争，同时在空气中使用环保的工作流体。由于零部件更少、复杂性更低、寄生损耗更低等额外优势，潜在的额外应用将广泛应用于建筑环境、国防和其他交通领域，强大的开发将带来高投资回报率（ROI）。

The heating, ventilation and air-conditioning (HVAC) systems are an energy intensive and present a challenge to all vehicles. This is exacerbated when power electronics and motors form a key part of the propulsion system such as in EV's. The HVAC system typically consumes between 20% - 40% of an EV's range depending on the HVAC system efficiency which can differ across different vehicles.This 6-month project builds on a recent IDP-14 feasibility study aiming to validate modelling work undertaken by the University of Brunel and small-scale in-house bench tests. The objective of this study is to run FeTu's novel Air-Cycle, a refrigerant free cooling system, in a purpose-built test rig that simulates an electric vehicle thermal management system. Previous work suggests FeTu's air-cycle can compete against traditional Vapour Compression Systems whilst using an environmentally friendly working fluid in air. With the additional benefits of fewer parts, less complexity and reduced parasitic losses.Potential additional applications would be widespread in built environment, defence and other transportation sectors, strong exploitation will lead to a high Return on Investment (ROI).
