Key Technologies for Enhancing Energy Efficiency of the Dew Point Air Cooler and its Manufacturing

该项目旨在通过拥有最先进空气冷却技术的领先英国大学/中国大学与拥有强大仪器和风扇制造能力的顶尖公司中国/英国之间的密切合作，开发一种新型的节能露点空气冷却器及相关制造工艺。它涉及四项技术任务：(1)开发冷却器设计和优化工具，确定冷却器性能数据(1-6月，由赫尔牵头，与清华和EBM-PAPST合作)；(2)建造和测试一台4千瓦额定冷却器，并确定相关的制造机器/工具(7-14月，由赫尔牵头，与EBM-PAPST和Sinogreen合作)；(3)开发计算机能源管理系统的制造流程，并生产20千瓦额定冷却器(7-18月，由Sinogreen牵头，与清华、EBM-Papst和Hull合作)；和(4)冷却器的安装、实时测量、公开演示和市场准备(19-24月，由Sinogreen牵头，与清华和赫尔)。预计(1)能源管理系统和模块化/数字化制造机床/工具的组合将减少制造过程中的能源消耗约20%；(2)与现有露点空气冷却器相比，新冷却器的冷却效率将提高约25%，COP将提高约40%。这一令人兴奋的技术发展飞跃可能会创造出一种新型空气冷却器，其价格/尺寸与传统蒸气压缩空调相当，但COP明显高于传统空气冷却器(高出7至8倍)。这一卓越的技术进步应该会在空调领域开辟一个巨大的全球新业务，从而对英国国内外的经济、工业和环境产生重大影响，中国说。

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.
