This research program will examine the application of engineered phase change materials (PCM) in the thermal management of energy conversion devices. Recent assessments show that Canada is warming at a faster rate than most regions in the world mainly due to the greenhouse gas (GHG) emissions. The transportation, building and electricity sectors were responsible for about half of Canada's total GHG emission in 2015. Therefore, there is a huge demand on energy conversion efficiency in these sectors in order to reduce the total GHG emission.The current research aims to tackle the sources of GHG emission in transportation and electricity sectors by enhancing thermal management systems through employing advanced engineered PCM. This research program includes numerical and experimental works that will be performed on two phases. In the first phase of investigations, various equipment such as thermal conductivity analyzer, X-ray diffraction and Raman spectroscopy are employed to characterize the nano-enhanced phase change materials (NePCM).In the second phase, the effectiveness of these materials in the thermal management of battery modules and photovoltaic (PV) cells is investigated through different experimental setups. These consist of a state-of-the-art cooling/heating wind tunnel, a fully automated battery tester and an infrared solar simulator. This system will be utilized to perform indoor tests on the battery modules and PV-cells under cold temperatures and different air velocities that are common in Canada. The short-term effects of these materials on the system performance, as well as their long-term effects on the global environment will be investigated. The results of the first phase of the current program will improve the understanding of the effects of nanoparticle networks on the thermophysical properties of the based PCM. It will also broaden the knowledge on the effects of sub-zero temperature solidification on the thermal conductivity enhancement of NePCM. Completion of the second phase will provide sound capability in the establishment of design and control strategies for the advanced PCM-based thermal management systems. The results will further assist to identify which aspects and properties need to be reinvestigated and altered to achieve the optimal performance of PCM-based thermal management systems in cold climate conditions.The research program proposed provides a solution to the most persistent low thermal conductivity problem of PCM in thermal management of batteries and PV cells. Additionally, it develops new knowledge that establishes the foundations for the highly efficient synthesis of carbon-based NePCM and the wide application of these environmental-friendly technologies in the Canadian climate. This work offers training of highly qualified personnel which will benefit the automotive, environmental and renewable energy industries in Canada.

本研究计划将研究工程相变材料（PCM）在能量转换设备热管理中的应用。最近的评估表明，加拿大的变暖速度比世界上大多数地区都快，主要原因是温室气体排放。2015年，运输、建筑和电力部门约占加拿大温室气体排放总量的一半。因此，这些行业对能源转换效率的需求很大，以减少温室气体排放总量。目前的研究旨在通过采用先进的工程PCM增强热管理系统来解决交通和电力行业的温室气体排放源。该研究计划包括数值和实验工作，将在两个阶段进行。在第一阶段的研究中，采用热导率分析仪、X射线衍射仪和拉曼光谱仪等设备对纳米增强相变材料（NePCM）进行了表征;在第二阶段，通过不同的实验装置研究了这些材料在电池组件和光伏（PV）电池热管理中的有效性。其中包括一个最先进的冷却/加热风洞，一个全自动电池测试仪和一个红外太阳模拟器。该系统将用于在加拿大常见的低温和不同空气速度下对电池模块和光伏电池进行室内测试。将研究这些材料对系统性能的短期影响以及对全球环境的长期影响。当前计划第一阶段的结果将提高对纳米颗粒网络对基于PCM的热物理性质的影响的理解。这也将拓宽知识的影响，零下温度凝固的导热系数增强的NePCM。第二阶段的完成将为先进的基于PCM的热管理系统的设计和控制策略的建立提供良好的能力。研究结果将进一步帮助确定哪些方面和属性需要重新调查和改变，以实现最佳性能的PCM为基础的热管理系统在寒冷的气候conditions.The研究计划提出的电池和光伏电池的热管理中的PCM最持久的低导热系数的问题提供了一个解决方案。此外，它还开发了新的知识，为碳基NePCM的高效合成以及这些环保技术在加拿大气候中的广泛应用奠定了基础。这项工作提供了高素质人才的培训，这将有利于加拿大的汽车，环境和可再生能源行业。
