The project's objectives are to assess the technical feasibility of developing a new range of high efficiency AirSource Heat Pumps (ASHPs) that achieve a significant improvement in performance compared to conventionalASHPs by virtue of the air supply to the ASHPs being pre-heated either by solar air collectors or, whereappropriate, by use of exhaust air flows. We will consider the feasibility of the concept for both new build andretrofit to existing buldings within both the residential and commercial sectors. The application of the newrange of high efficiency ASHPs will be for the supply of renewable heating and cooling (where used inconjunction with thermally driven cooling systems) in buildings. The project's activities will include appraisal ofsystem design options, development of a detailed thermodynamic system design model and demand-sidemodel, formulation of control and modulation strategies, investigation into optimisation of system components(with particular attention to working fluids, fluid flow rates, evaporator, condenser and controller), calculationof theoretical system performance in different climates and undertaking of cost benefit analysis.

该项目的目标是评估开发一系列新的高效空气源热泵（ASHP）的技术可行性，与传统的ASHP相比，通过太阳能空气收集器或适当的废气流预热空气供应到ASHP，实现性能的显着改善。我们会考虑这个概念在新建楼宇和改装现有楼宇方面的可行性，包括在住宅和商业楼宇方面。高效ASHP的最新应用将用于建筑物中的可再生加热和冷却（与热驱动冷却系统结合使用）。该项目的活动将包括评估系统设计方案、开发详细的热力系统设计模型和需求方模型、制定控制和调节策略、调查系统部件的优化（特别注意工作流体、流体流速、蒸发器、冷凝器和控制器）、计算不同气候条件下的理论系统性能以及进行成本效益分析。
