The UK has set an ambitious target to cut its greenhouse gas emissions by at least 80% by 2050, relative to 1990 levels. Currently, heat accounts for nearly half of the energy consumption in the UK and a third of the nation's carbon emissions. To achieve the UK's carbon reduction target, the residential heating sector has to be substantially decarbonised. A wide range of technologies are at different stage of developments but their energy efficiencies are not all satisfactory. There is clearly a big gap between the demand and supply of cost-effective heating technologies in the UK. There is a urgent need for innovation of low-carbon heating technologies in the UK.This project develops a novel, gas-powered heat pump that integrates a small-scale Rankine Cycle power generator using organic working fluids (i.e. refrigerants) with a vapour-compression heat pump by means of a novel coupling technology. Both the heat rejected by the Rankine Cycle power generator and the heat provided by the heat pump are fully utilised for heating. The novel design allows the condensing temperature of the heat pump to be much lower than that of a single electrically-powered heat pump leading to much higher energy performance. The compact heat exchangers are used to enable the heat pump much small in size. The novel design of the combustion heat exchanger enables efficient and clean combustion processes. The novel heating technology developed through this project is much more efficient than traditional heating technologies, and therefore can significantly reduce the carbon emissions from the residential heating sector in the UK, if widely installed.

相对于1990年的水平，英国设定了一个雄心勃勃的目标，将其温室气体排放量至少减少了80％。目前，热量占英国能源消耗的近一半，是该国排放量的三分之一。为了达到英国的降低碳量目标，必须实质上脱碳。广泛的技术处于发展的不同阶段，但它们的能源效率并不令人满意。在英国，需求和供应有效的供暖技术的需求和供应之间显然存在很大的差距。迫切需要在英国进行低碳加热技术的创新。该项目开发了一种新型的，燃气的热泵，该热泵使用有机工作流体（即制冷剂）与蒸气压缩热泵通过一种新型的兰型工作流体（即制冷剂）整合了小型的兰肯循环发电机。兰金循环发电机拒绝的热量和热泵提供的热量都完全用于加热。新颖的设计使热泵的冷凝温度远低于单个电动热泵的温度，导致能量性能更高。紧凑的热交换器用于使热泵的尺寸很小。燃烧热交换器的新型设计实现了有效，清洁的燃烧过程。通过该项目开发的新型加热技术比传统的供暖技术要高得多，因此，如果安装广泛，英国住宅供暖部门的碳排放量可以大大减少。
