The proposed project is aimed to investigate an innovative heat pump utilizing the Ericsson thermodynamic cycle in earlyconcept stage. The proposed system is a new technology that could reduce the energy demands in many areas. Theproposed project fits the scope in engines & thermodynamic cycles, and energy efficiency.The proposed mechanical heat pump utilizing the Ericsson thermodynamics cycle would have near Carnot Cycle idealefficiency due to unique innovations of the design:1) Flat rotors that create the optimum heat exchange area;2) Independent Induction Motor Generators allow continuously variable rotor rotational velocity and thus compression ratio,volume, and compression rate, allowing near isothermal compression and expansion;3) Continuous cycling of the fluid allows for near Isobaric heat exchange in varying conditions;4) Efficient and simple Induction Motor-Generators - requiring no mechanical linkage and allowing the device to behermetically sealed with the inner stator within, greatly increasing service life;5) Separate, compression, heat exchanger, and expander chambers mean no wasted work on 'dead air', and no thermalcreep between parts of the device, thus eliminating efficiency losses of other systems;6) Continuous cycling with constant fluid compression, heat exchange, and expansion, unlike other systems;7) Use of clearance seals eliminates traditional sealing issues. Only four moving parts, no valves, and hermetically sealingthe device and allows very long service life.The proposed Ericsson heat pump would provide efficient and environmentally friendly cooling. The majority of coolers,refrigerators, and air conditioners today are based on the vapour compression cycle using CFC's (Freon). Althoughefficient, the use of CFC's has significant detrimental environmental issues and its discontinued use is mandated. Theproposed Ericsson system would provide an extremely low maintenance, highly efficient engine able to draw energy fromsolar, geothermal, waste heat, and most any other energy source. The engine would be silent and vibration free, making itapplicable to many other applications.The development of the proposed Ericsson heat pump/engine would provide huge global market opportunities for which theUK can develop and grow innovative businesses to deliver world-leading solutions.The unknown factors and risks in this development make it difficult for the partners to take on and the Innovate UK fundingwould provide the essential support to enable the consortium expertise areas to come together and create a novel systemcreating many jobs across the supply chain with energy consumption per unit cut by 40%, Payback time: 1.5 to 3 years,and saving about 20 tonnes of CO2 per unit (5kW) per year, achieving UK's Government target.

该项目的目的是研究一种创新的热泵，利用爱立信热力循环在早期概念阶段。该系统是一项新技术，可以减少许多领域的能源需求。该项目符合发动机和热力学循环以及能源效率的范围，所提出的利用埃里克森热力学循环的机械热泵将具有接近卡诺循环的理想效率，这是由于其独特的设计创新：1）扁平转子，创造了最佳的热交换面积; 2）独立感应电动机发电机允许连续可变的转子旋转速度，从而允许连续可变的压缩比、体积和压缩率，允许接近等温的压缩和膨胀;3）流体的连续循环允许在变化的条件下接近等压的热交换;4）高效和简单的感应电动机-发电机-不需要机械连接，并且允许装置与内部定子密封，大大增加使用寿命; 5）独立的压缩室、热交换室和膨胀室意味着在“死空气”上没有浪费的功，并且在装置的部件之间没有热蠕变，从而消除了其他系统的效率损失; 7）间隙密封的使用消除了传统的密封问题。只有四个运动部件，没有阀门，并且密封设备，使用寿命很长。拟议的爱立信热泵将提供高效且环保的冷却。今天，大多数冷却器，冰箱和空调都是基于使用CFC（氟利昂）的蒸汽压缩循环。尽管高效，但使用CFC具有显著的有害环境问题，并且其停止使用是强制性的。爱立信提出的系统将提供一个极低的维护，高效的发动机，能够从太阳能，地热，废热，和大多数其他能源。发动机将是无声和振动自由，使其适用于许多其他应用。拟议的爱立信热泵/发动机的开发将提供巨大的全球市场机会，英国可以为此开发和发展创新企业，为世界提供领先的解决方案。这一发展中的未知因素和风险使合作伙伴难以承担，而英国创新基金将提供必要的支持，联合体的专业领域走到一起，创造一个新的系统，在整个供应链中创造许多就业机会，单位能源消耗减少40%，投资回收期：1.5至3年，每年每单位（5 kW）节省约20吨二氧化碳，实现英国政府的目标。
