Development of a new generation of high efficiency heat pumps using pre-heated air supply

该项目的目标是评估开发一系列新型高效空气源热泵（ASHPs）的技术可行性，与传统的空气源热泵相比，由于空气源热泵的空气供应由太阳能空气收集器预热，或者在适当的情况下使用废气流，从而实现性能的显著改善。我们会考虑在住宅及商业界别内兴建新楼宇及改造现有楼宇的可行性。新型高效空气源热泵的应用将用于建筑物的可再生供暖和制冷（与热驱动冷却系统一起使用）。该项目的活动将包括评估系统设计方案、制定详细的热力系统设计模型和需求侧模型、制定控制和调制策略、调查优化系统组件（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。

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.
