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. 廣州市華德工業(yè)有限公司羿歌空調(diào)技術(shù)參觀活動順利舉行。 這次的參觀學(xué)習(xí)活動共有26名成員參加，我們的到來受到了李志明總裁熱烈的歡迎。作為參觀的開端，他為我們做了一個(gè)羿歌空調(diào)的技術(shù)介紹。 李志明總裁給我們介紹的是一種新型的環(huán)保的蒸發(fā)冷卻式中央空調(diào)。華德羿歌空調(diào)是第一家將蒸發(fā)冷卻式技術(shù)運(yùn)用到商業(yè)空調(diào)領(lǐng)域的企業(yè)，蒸發(fā)冷卻式技術(shù)結(jié)合了水冷和風(fēng)冷的優(yōu)勢。 在空調(diào)內(nèi)部，高溫的氣態(tài)冷媒通過板管冷凝器，被板管冷凝器表面的水膜吸收熱量。內(nèi)置的風(fēng)扇提高了板管冷凝器和高溫氣態(tài)冷媒之間的熱交換效率。 這種新型的中央空調(diào)整合了冷凝器和冷水塔到一個(gè)系統(tǒng)里面，因?yàn)槲覀儾恍枰渌?，所以連接冷凝器和冷卻塔的水管和水泵也不需要了。因此羿歌空調(diào)可以有效地節(jié)約能源，水資源和建筑面積。 相比于水冷式中央空調(diào)，羿歌蒸發(fā)冷卻式中央空調(diào)節(jié)約了大約50%的水和15%的能耗。相比于風(fēng)冷式中央空調(diào)，羿歌蒸發(fā)冷卻式中央空調(diào)降低了大約30%的能耗。 另外，智能控制系統(tǒng)和自動管道清潔系統(tǒng)讓羿歌空調(diào)維持高效率的運(yùn)作并且降低了機(jī)組維護(hù)成本。技術(shù)員也分享了蒸發(fā)冷空調(diào)在不同領(lǐng)域的項(xiàng)目運(yùn)行狀況，并且指出了可能存在的一些問題和解決的方案。 技術(shù)講解過后，我們進(jìn)入了互動的問答環(huán)節(jié)，雙方對空調(diào)領(lǐng)域的一些經(jīng)驗(yàn)和見解做出了交流，并參觀了空調(diào)的生產(chǎn)車間。最后我們參觀了被安裝在商業(yè)大廈樓頂，正在運(yùn)行的羿歌蒸發(fā)冷卻式大功率空調(diào)機(jī)組。在控制機(jī)房里，技術(shù)員給我們詳細(xì)介紹了羿歌蒸發(fā)冷卻式中央空調(diào)的數(shù)據(jù)控制裝置。所有參觀的工程師都對蒸發(fā)冷卻式中央空調(diào)的運(yùn)作方式表達(dá)濃厚的興趣，并且通過互動討論，提高了他們對蒸發(fā)冷卻式空調(diào)的優(yōu)勢了解。 這次代表所有參觀人員，感謝華德羿歌的總裁和他的員工給了我們一個(gè)專業(yè)的技術(shù)講解并且?guī)覀儏⒂^工廠生產(chǎn)線和現(xiàn)場的項(xiàng)目。通過這次的參觀，我們的會員深入地了解了創(chuàng)新型的中央空調(diào)技術(shù)和該技術(shù)對社會技術(shù)進(jìn)步，環(huán)境的美化和經(jīng)濟(jì)進(jìn)步的意義。 轉(zhuǎn)載自香港工程師學(xué)會 |
