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.

广州市华德财产无限公司羿歌空调手艺观赏勾当顺遂进行。

    此次的观赏进修勾当共有26名成员参与,咱们的到来遭到了李志明总裁强烈热闹的接待。作为观赏的初步,他为咱们做了一个羿歌空调的手艺先容。

    李志明总裁给咱们先容的是一种新型的环保的蒸发冷却式中心空调。华德羿歌空调是第一家将蒸发冷却式手艺应用到贸易空调范畴的企业,蒸发冷却式手艺连系了水冷微风冷的上风。

    在空调外部,低温的气态冷媒经由过程板管冷凝器,被板管冷凝器外表的水膜接收热量。内置的电扇前进了板管冷凝器和低温气态冷媒之间的热互换效力。

    这类新型的中心空调剂合了冷凝器和冷水塔到一个体系外面,由于咱们不须要冷水塔,以是毗连冷凝器和冷却塔的水管和水泵也不须要了。是以羿歌空调能够有用地节俭动力,水资本和修建面积。

    比拟于水冷式中心空调,羿歌蒸发冷却式中心空调理俭了约莫50%的水和15%的能耗。比拟于风冷式中心空调,羿歌蒸发冷却式中心空调下降了约莫30%的能耗

    别的,智能节制体系和主动管道洁净体系让羿歌空调保持高效力的运作并且下降了机组保护本钱。手艺员也分享了蒸发冷空调在差别范畴的名目运转状态,并且指出了能够存在的一些题目和处置的打算。

   手艺讲授事后,咱们进入了互动的问答关键,两边对空调范畴的一些经历和看法做出了交换,并观赏了空调的出产车间。最初咱们观赏了被装配在贸易大厦楼顶,正在运转的羿歌蒸发冷却式大功率空调机组。在节制机房里,手艺员给咱们具体先容了羿歌蒸发冷却式中心空调的数据节制装配。一切观赏的工程师都对蒸发冷却式中心空调的运作体例抒发稠密的乐趣,并且经由过程互动会商,前进了他们对蒸发冷却式空调的上风领会。

   此次代表一切观赏职员,感激华德羿歌的总裁和他的员工给了咱们一个专业的手艺讲授并且带咱们观赏工场出产线和现场的名目。经由过程此次的观赏,咱们的会员深切地领会了立异型的中心空调手艺和该手艺对社会手艺前进,情况的丑化和经济前进的意思。
