Passive Strategies for Improving Energy Efficiency of Buildings - Optimisation of a low-energy ventilation façade with novel integration of Helical Co

建筑环境通过其采暖、通风和空调（HVAC）需求占全球能源消耗的30-40%，这是人们在建筑物中度过约90%日常生活的结果。这占全球碳排放量的40-50%，因此需要在建筑居民消耗能源的方式以及提供和利用能源的技术和建筑服务方面进行重大改变。该项目解决了增加新的、创新的低能耗HVAC技术的研究和开发的动机。具体来说，本研究项目的主要目的是研究和优化低能耗的加热和冷却通风系统，采用螺旋盘管传热装置（HCHTD）的新型集成，以英国为重点气候。研究的重点是通过对螺旋线圈的各种几何特征进行详细的参数化研究，以优化HCHTD的效率。通过完成这一优化，以及对传统通风立面结构的重新设计以改善通风性能，我将能够为风洞测试和实地研究验证目的制作最终概念的缩放原型。本研究涉及的主要方法是文献综述、利用ANSYS软件包进行计算流体动力学（CFD）建模、风洞试验和生命周期评估（LCA）。该项目的长期目标是在技术上和经济上发展这一概念，以获得专利和商业化。

The built environment represents a significant 30-40% of global energy consumption through its Heating, Ventilation and Air-Conditioning (HVAC) demands which are resultant of people spending around 90% of their daily lives in buildings. This contributes 40-50% of global carbon emissions, and therefore there needs to be a drastic change in the way that building inhabitants consume energy and, in the technology, and building services which provide and utilise it. This project addresses the motive for increasing the research and development of new, innovative low energy HVAC technologies. Specifically, the main aim of this research project is to investigate and optimise a low-energy heating and cooling ventilation façade with novel integration of Helical Coil Heat Transfer Device (HCHTD) using the UK as the focus climate. The research will focus on the optimisation of the HCHTD for maximum efficiency through a detailed parametric study of various geometric features of the helical coils. By completing this optimisation, as well as a re-design of the traditional ventilation façade structure to improve ventilation performance, I would be able to produce a scaled prototype of the final concept for wind tunnel test and field study validation purposes. The main methodologies involved in this research are literature review, Computational Fluid Dynamics (CFD) modelling through ANSYS package, Wind Tunnel tests and Life Cycle Assessment (LCA). The long-term objective of this project is to developing the concept technologically and economically for patent and commercialisation.
