Report for Technical Visit to ETCO Chiller Factory in Guangzhou

     The technical visit to ETCO Chiller Factory was successfully organized on 9 August 2014. A total of 26 members joined the visit. Upon arrival, we are warmly welcome with given a technical presentation by Mr. Li Zhi Ming CEO of the Guangzhou Wide Industrials Co; Ltd.as a start.
 

     A new type of environmentally friendly evaporative cooled chiller was introduced.ETCO is the first company applying this technology to combine the functions of water cooled and air cooled chiller. Inside the chiller unit, high temperature gas refrigerant passes through the condensing plate-tube and cool down as the water film on the plate-tube absorbs the heat. This process is enhanced by the fansinstalled to improve the heat exchange rate between the condensing plate-tube and the refrigerant. As this new type chiller integrates condenser and cooling tower into onesystem, cooling tower is not required and hence the water pipe between the condenser and cooling tower can be eliminated. Therefore, evaporative condenser can reduce energy, water usage and the building area. When compared with water cooled chiller, there is about 50% water saving and 15% energy saving for evaporative cooled chiller. It also saves about 30% energy comparing with air cooled chiller. In addition, intelligent control systemand automatic tube cleaning system were also designed to help the central air-conditioning to maintain high efficiency and save maintenance cost. The speaker also shared different projects using evaporative cooled chiller and pointed out some problems facing in the real application.After the presentation,an interactive experience sharing was exchanged through question-and-answersession. Then we are led to visit the chiller products in the show room.
 

     Finally,we were led to visit a commercial building where the mega evaporative friendly chiller plant has been installed on the roof and in operation. In the control room, the digital control on evaporative chiller plant is also introduced. The participants expressed much interest in the operation of evaporativecold chiller and the interactive discussions were carried out to enhance their understanding of evaporative cooled chiller and its advantages. On behalf of Materials Division and the participants, we would like to thank the CEO and his staff to give us a good technicalpresentation and also led us for the visit. Through out the visit, our members can learn how innovative and creative on the products would benefit and enhance social, environment and economic development.

2022卡塔尔世界杯官网羿歌空调技术参观活动顺利举行。

    这次的参观学习活动共有26名成员参加，我们的到来受到了李志明总裁热烈的欢迎。作为参观的开端，他为我们做了一个羿歌空调的技术介绍。

    李志明总裁给我们介绍的是一种新型的环保的蒸发冷却式中央空调。华德羿歌空调是第一家将蒸发冷却式技术运用到商业空调领域的企业，蒸发冷却式技术结合了水冷和风冷的优势。

    在空调内部，高温的气态冷媒通过板管冷凝器，被板管冷凝器表面的水膜吸收热量。内置的风扇提高了板管冷凝器和高温气态冷媒之间的热交换效率。

    这种新型的中央空调整合了冷凝器和冷水塔到一个系统里面，因为我们不需要冷水塔，所以连接冷凝器和冷却塔的水管和水泵也不需要了。因此羿歌空调可以有效地节约能源，水资源和建筑面积。

    相比于水冷式中央空调，羿歌蒸发冷却式中央空调节约了大约50%的水和15%的能耗。相比于风冷式中央空调，羿歌蒸发冷却式中央空调降低了大约30%的能耗。

    另外，智能控制系统和自动管道清洁系统让羿歌空调维持高效率的运作并且降低了机组维护成本。技术员也分享了蒸发冷空调在不同领域的项目运行状况，并且指出了可能存在的一些问题和解决的方案。

   技术讲解过后，我们进入了互动的问答环节，双方对空调领域的一些经验和见解做出了交流，并参观了空调的生产车间。最后我们参观了被安装在商业大厦楼顶，正在运行的羿歌蒸发冷却式大功率空调机组。在控制机房里，技术员给我们详细介绍了羿歌蒸发冷却式中央空调的数据控制装置。所有参观的工程师都对蒸发冷却式中央空调的运作方式表达浓厚的兴趣，并且通过互动讨论，提高了他们对蒸发冷却式空调的优势了解。

   这次代表所有参观人员，感谢华德羿歌的总裁和他的员工给了我们一个专业的技术讲解并且带我们参观工厂生产线和现场的项目。通过这次的参观，我们的会员深入地了解了创新型的中央空调技术和该技术对社会技术进步，环境的美化和经济进步的意义。
