The project aims to develop a novel energy efficient dew point air cooler and associated manufacturing process, throughthe close collaboration among the leading UK/China Universities with the most advanced air cooling technologies and thetop China/UK companies having strong manufacturing capacities in instruments and fans. It involves four technical tasks:(1) development of the cooler design and optimization tool and determination of cooler performance data (Month 1-6, led byHull, with Tsinghua and ebm-papst); (2) construction and testing of a 4 kW rated cooler, and identification of associatedmanufacturing machines/tools (Month 7-14, led by Hull, with ebm-papst and Sinogreen); (3) development of amanufacturing process with a computerised energy management system, and production of a 20 kW rated cooler (Month 7-18, led by Sinogreen, with Tsinghua, ebm-papst and Hull); and (4) installation, real-time measurement, publicdemonstration and marketing preparation of the cooler (Month 19-24, led by Sinogreen, with Tsinghua and Hull).It is expected that (1) a combination of the energy management system and modular/numerical manufacturingmachines/tools will reduce energy use of the manufacturing process by around 20%; (2) the new cooler will achieve around25% higher cooling efficiency and 40% higher COP, compared with existing dew point air coolers. This exciting leapforwardin technological development could create a new type of air cooler that has comparable price/size to traditionalvapour compression air conditioners but significantly higher COP over the traditional ones (7 to 8 times higher). Thisdistinguished technological advance should open up an enormous new global business in the air conditioning sector, thuscreating considerable impact on the economy, industry and the environment within the UK, China and beyond.
