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的高效空气源热泵的技术可行性，这些空气源热泵通过太阳能空气集热器或在适当情况下利用废气流动对空气源热泵进行预热，从而实现与传统空气源热泵相比在性能上的显著改进。我们会考虑在住宅和商业楼宇内兴建新楼宇和加装现有楼宇的概念是否可行。新型高效热泵的应用将用于建筑物中的可再生供暖和制冷(与热力驱动的制冷系统结合使用)。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侧模型，制定控制和调节策略，调查系统组件的优化(特别关注工质、流体流量、蒸发器、冷凝器和控制器)，计算系统在不同气候下的理论性能，并进行成本效益分析。

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.
