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.

拟议的项目旨在研究一种创新的热泵，利用爱立信热力学循环在早期概念阶段。该系统是一项新技术，可以减少许多地区的能源需求。提议的项目适合发动机和热力学循环的范围，和能源效率。由于设计的独特创新，利用爱立信热力学循环的机械热泵将具有接近卡诺循环的理想效率：1)创造最佳热交换面积的扁平转子；2)独立的感应电机发电机允许连续可变转子转速，从而实现压缩比、体积和压缩率，实现近等温压缩和膨胀；3)流体的连续循环允许在不同条件下进行近等压热交换；4)高效简单的感应发电机-无需机械连接，设备与内部定子完全密封，大大提高了使用寿命；5)独立的压缩室，热交换器和膨胀室意味着没有浪费在“死空气”上的工作，并且设备各部分之间没有热蠕变，从而消除了其他系统的效率损失；6)连续循环，流体不断压缩、换热、膨胀，不同于其他系统；7)使用间隙密封消除了传统的密封问题。只有四个运动部件，没有阀门，和密封装置，并允许很长的使用寿命。拟议中的爱立信热泵将提供高效和环保的冷却。今天，大多数冷却器、冰箱和空调都是基于使用氟利昂的蒸汽压缩循环。氯氟烃的使用虽然有效，但对环境有严重的有害问题，因此必须停止使用。爱立信提出的系统将提供极低的维护，高效的发动机，能够从太阳能，地热，废热和大多数其他能源中获取能量。这种发动机静音且无振动，因此适用于许多其他应用。拟议中的爱立信热泵/发动机的开发将为英国提供巨大的全球市场机会，英国可以开发和发展创新业务，提供世界领先的解决方案。这一发展中的未知因素和风险使合作伙伴难以承担，而Innovate UK的资金将提供必要的支持，使联盟的专业领域能够聚集在一起，创造一个新的系统，在整个供应链中创造许多就业机会，每单位能耗降低40%，投资回报时间：1.5至3年，每单位每年节省约20吨二氧化碳（5kW），实现英国政府的目标。
