项目摘要

This project is a feasibility study into the proposal of using solar collectors which when integrated into buildings can prewarm the air fed into ASHP (Air Source Heat Pumps)Pre-feasibility modelling indicates that by using solar air collectors to pre-heat the air supply to specially optimised ASHPswe will be able to increase the efficiency of ASHPs to the extent that 1) the carbon emissions (per kWh of heat) from theiruse will be significantly lower than the emissions associated with energy efficient gas boilers and 2) the cost of heat will(within the 2020s) become lower than that from efficient gas boilers.The findings could therefore lead to a step-change in the competitiveness of ASHPs relative to gas boilers. This willaccelerate the mainstream deployment of ASHPs in the UK, initially within new build housing and new commercialbuildings and subsequently into the existing UK building stock.The project will specifically investigate:Appraisal of system design optionsDevelopment of a detailed thermodynamic system design model and demand-side model(s),Formulation of control and modulation strategiesInvestigation into optimisation of system components (with particular attention to working fluids, fluid flow rates, heatexchanger and controller)Calculation of theoretical system performance in different climates and undertaking of cost benefit and benchmarkinganalysis.This project will contribute towards addressing the UK's energy trilemma by reducing emissions by leading to a supply ofrenewable heat with lower carbon emissions than mains gas and of renewable cooling with significantly lower emissionsthan electricity powered compressor-based cooling systems; improving security of supply by significantly reducing demandfor fossil fuels; and reducing cost by providing a high-efficiency ASHP capable of generating heat (for space heating, waterheating and cooling) at a lower cost than both mains gas and other renewable energy/"clean energy" options.

这个项目可行性研究的建议使用太阳能收集器,当集成到建筑物可以prewarm空气送入ASHP(空气源热泵)可行性预测模型表明,通过使用太阳能空气收集器预热空气供应专门优化ASHPswe能够增加ASHPs的效率在一定程度上,1)碳排放(每千瓦时的热量)theiruse将明显低于排放与能源有关高效燃气锅炉和(2)热能成本（在21世纪20年代）将低于高效燃气锅炉。因此，研究结果可能导致空气源热泵相对于燃气锅炉的竞争力的逐步变化。这将加速空气源热泵在英国的主流部署，最初是在新建住宅和新的商业建筑中，随后进入现有的英国建筑库存。该项目将具体研究：系统设计方案的评估、详细的热力学系统设计模型和需求侧模型的开发、控制和调制策略的制定、系统组件优化的研究（特别注意工作流体、流体流速、热交换器和控制器）、不同气候条件下理论系统性能的计算、成本效益和基准分析的承担。该项目将有助于解决英国的能源三难困境，通过提供碳排放量低于天然气的可再生热能和排放量显著低于电力压缩机冷却系统的可再生冷却来减少排放；通过大幅减少对化石燃料的需求来改善供应安全；并通过提供能够产生热量（用于空间加热，水加热和冷却）的高效空气源热泵来降低成本，其成本低于主要天然气和其他可再生能源/“清洁能源”选项。
